Project Management - Research Paper Example Studies show that, a cost-benefit analysis is used by organizations to carry out evaluation of the total projected costs in a project concerning the expected overall benefits; in view of the viability of the proposed implementation project. costs unit entry extended Implementation process planning Hours 260 11,245 Labor contract Dollars 16000 16,000 Internal implementation labor Hours 900 38,925 Input/ capital cost Dollars 16000 16,000 Implementation cost 82,170 proceeding Operational costs Dollars/Month 1100 1,100 Maintenance cost Dollars/Month 1300 1,300 Proceeding/ongoing monthly costs 2,400 Remunerated implementation cost 1,600 Monthly cost $4,000 For an organization, which is considering the implementation of an ‘outsourcing payroll service system’, the direct revenue enhancement and cost reductions will involve increase in employee productivity. This is because the employees have now the time to focus on many productive activities, which is essence, will improve pr ofitability for the company. Concerning cost reduction, the other direct way to reduce cost is avoidance of the IRS penalties. These forfeits may come because of improper bookkeeping and outflows. Through the outsourcing services, many companies may greatly avoid such penalties; the income heightening can be reduced basing on the organizational expenses. This is where the outsourcing services allow employees to launch reimbursement claims over the internet or online, which more beneficial and time is saving. On the other hand, indirect revenue enhancement may involve the process of building brands in other countries; brand extension. In essence, this may be a case where the outsourced company uses and features the partner company`s logo branding; this allows the company to show case the company name and the logo in all customer and employee accessed pages. The best technology employment is one of the indirect methods of cost reduction. It could profit trivial industries, with less e xpertise fortes. To this end, there are risks associated with the implementation of a new payroll system in an organization. According to findings, any implementation process carries with it some degree of risks. This calls for a risk plan to be included in the implementation process. In most cases, the focus of registers has been on the technology; its functionality and the influence its failure may create on the overall project. The common risks associated with new payroll systems is, the repercussions when the system fails to deliver a live operation by a particular time the perceived contingence plan in place. The other risk is the change impact of organizational and political consequences associated with the movement from an old payroll model or system to the new system where the HR responsibility becomes more neglected. To address these risks, studies indicate that, most new systems are designed while employing best practice model. This requires great responsibility for system s and their ownership within the human resource; this allows the transfer of data being processed within the human resource payroll department, however, its working, majorly relies on the project requirements. It is only significant then to consider how to manage the interface process involving two parts of one organization with different requirements. In has been found that, in situations where there exists integrated systems, which have not been part of the operational culture or life of the human resource

Kinesin Moves by an Asymmetric Hand-Over-Hand Mechanism

Kinesin Moves by an Asymmetric Hand-Over-Hand Mechanism Introduction This review discusses the motion of kinesin, a double headed motor protein. A study was conducted to determine which of two motion patterns is the one which describes the movement of this protein: the inchworm model, or the hand-over-hand model. What is Kinesin? Kinesin is a protein in a class of motor proteins which are powered by the hydrolysis of ATP – the molecule responsible for transporting chemical energy for metabolism [1]. Kinesin transports large cargo about cells by walking along microtubules, hydrolysing one molecule of ATP per step [2]. It has been proposed than the force of the protein binding to the microtubule propels the cargo along [3]. Kinesin moves to the â€Å"plus† end of the microtubule, meaning it transports the cargo from the centre to the edge of the cell [4]. There is evidence that some kinesins have a role in mitosis (cell division), by separating microtubules or depolymerising them [5]. The Models The inchworm model describes motion with one â€Å"arm† of the protein moving forward, followed by the other, with the first arm always in the lead. There are two types of inchworm motion, symmetric and asymmetric, which are shown in the image below. The symmetric model takes smaller steps, so only one arm moves at a time. Asymmetric motion takes a single step, at the middle of which both arms move. In the hand-over-hand model, alternating arms move forward over each other. In the symmetric case, the molecule rotates in the same direction every time, but in the asymmetric case the molecule rotates in alternating directions. These models are shown in the image below. Main Results The papers main result shows that the kinesin protein moves using an asymmetric hand-over-hand mechanism. To reach this verdict, a variety of single molecule experiments were performed. They established that the individual kinesin dimers make discrete steps at random intervals along the microtubule, and may take as many as one hundred 8 nm steps before releasing. The movement is processive, meaning that the protein can make many consecutive steps without releasing the substrate (the molecule on which it acts – here, the microtubule). This motion exists even when external forces up to several pN are applied, which indicates part of the protein stays attached at all times. The active part of kinesin is composed of a dimer, with two identical heavy chains, each with a â€Å"head† attached to a common stalk. These chains join to a short â€Å"neck† composed of single polypeptide chains. The heavy chains are coiled round each other to allow the rotation necessary for the hand-over-hand model. This rotation is about the neck, but the motion of the heads turning would continue winding, summing until the heavy chains would join into a common stalk, preventing independent rotation. A study was conducted [6] showing that no significant rotation occurs of the stalk during the stepping motion. For a symmetric model, a large rotation (about 180 degrees) was expected in the hand-over-hand models. The basis for the definition of â€Å"symmetric† here was in three dimensions: the structure of the kinesin and microtubule must be identical at the start and end of each ATP hydrolytic cycle, except for the two heads having swapped places [6]. An example of this is simply the dimer rotating half a revolution about an axis perpendicular to the microtubule each step [7], hence the prediction for a rotation of 180 degrees. However this was ruled out, and an inchworm model was proposed. In this, only one of the heads is active in hydrolysis, but the possibility of an asymmetric hand-over-hand motion remained. This would mean that the head and neck move in such a way that the overall rotation of the stalk is suppressed, instead alternating between two distinct structures [8]. How They Were Obtained The step motion of individual native and recombinant (formed in the lab by combining genetic material from multiple sources) kinesin molecules was measured, using optical force-clamp apparatus. This technique uses light from a tightly focussed laser to trap small, polarisable particles in a potential well near the focal point [9]. It was found that the intrinsic stepping rates alternated between two different values for each step, meaning the molecules â€Å"limped†. The difference in steps implies there was an alternation in underlying molecular configurations, meaning the motion could not be fully symmetric (such as the inchworm and symmetric hand-over-hand motions should be). The discovery of the limp, along with other nano-mechanical properties, means the protein moves with an asymmetric hand-over-hand motion. Single molecules of kinesin were attached to microscopic beads, serving as markers for position and as handles for external forces. An optical trap was then used to capture the individual beads that diffused whilst carrying the kinesin, which were placed near the microtubules. This was while kinesin bound and moved. The motion was then tracked using nanometer level precision. A feedback-controlled force lamp was used to apply a constant backwards load during the motion, in order to reduce the Brownian fluctuations and improve the spatiotemporal resolution. It also allowed for the kinesin to move further, taking more steps, in order to show statistical significance. The Results A derivative of Drosophila melanogaster kinesin (DmK401) was shown to have an obvious limp, with large time differences in the steps despite the stochastic nature (and ensuing variability). Statistical analysis showed significant differences in the average step times for both slow and fast steps. The durations of the steps were then calculated as Ï„slow = 136  ± 6 ms and Ï„fast = 24  ± 1 ms. The limp factor, L, can then be calculated as the ratio of the mean duration of the slow stepping time to the mean duration of the fast stepping time. The distribution showed significant limping for the majority of molecules, but there was wide variation in the results. 63% of records showed L > 4, and the average was L = 6.45  ± 0.31. Some motors took many runs and had consistently higher limp factors than others, but the distribution was broad and the populations could not be separated of limping and non-limping molecules. Other kinesin molecules, such as the native squid kinesin, showed almost no evidence of limping – the same calculations were applied as to DmK401, and the times were calculated to be Ï„slow = 90  ± 4 ms and Ï„fast = 54  ± 2 ms. The difference is much smaller than that for DmK401. The limp distribution was also found to be narrower, with the average limp factor being L = 2.23  ± 0.14, only slightly higher than the estimated value for a non-limping molecule, L ~ 1.8. The test was then done with kinesin derivates of Drosophila which had increasing stalk lengths. Longer stalks mean the motors are less likely to limp. The largest stalk tested was that of DmK871, and this had a limp factor of L = 2.16  ± 0.17, which was indistinguishable from native squid kinesin. There was also a correlation between an increasing limp factor (therefore shorter stalks) and an increase in characteristic lifetime of the slow step time, whereas the fast step remained invariant. This suggests the limping comes from one head alone, and the other is indifferent. A bacterial expression of a derivative of human kinesin (HsK413) also limped, with limp factor = 2.98  ± 0.25, much greater than the native squid kinesin, but still less than DmK401 and DmK448. Rarely, squid kinesin molecules seemed to limp, making outliers – some of which limped consistently. Discussion As both native and bacterially expressed dimers from different species can limp, this behaviour may be a result of a common mechanism describing how all kinesin molecules move. The alternation between short and long step times during limping reflects an alternation between the intrinsic rate (the rate with which the population increases) and the time it takes to leave each phase where neither head is moving. This implies the structure of the kinesin-microtubule complex is different at the end of sequential steps. The mechanism describing the movement of kinesin must therefore be asymmetric, meaning the molecular configuration switches after each step. Symmetric mechanisms, by definition, cannot account for switching – inchworm models will not limp without additional (asymmetric) features, nor will symmetric hand-over-hand models. The detail of how kinesin motors move is not well known or understood, so we cannot look at how limping could relate to the structure of the motion, but there are some suggestions based on the asymmetric hand-over-hand mechanism. Limping could be caused by misalignment of the stalk coils, meaning the necks would be different lengths, hence the head with a shorter neck would need extra time to find the next binding site using a diffusional search and overall slowing the kinetics. Another option is that there could be over- or under-winding of the coils from hand-over-hand motion, causing torsional asymmetry. The energy required to coil or uncoil the stalk would be reduced, changing the equilibrium and the rate with which the head moves forward. Whilst there is no immediate explanation for the effect whereby the shorter stalks result in longer slow stepping times, it may be incorporated into later studies with further assumptions. However, these experiments have shown that more approaches are needed for single-molecule experiments to answer these questions. Despite the exact mechanism not being known, the experiments do show that the kinesin motors limp, and making the asymmetric hand-over-hand mechanism the most likely. Why is this Significant? This is a breakthrough in the field, as more detail can now be found on how biological motors move. By establishing how kinesin moves, other motors can be analysed to find their mechanisms for movement, and this helps to further our understanding of biology. The same experiment can be done with other proteins, or more experiments can be done with kinesin to better understand certain factors – for example, why the slow stepping times correlate to shorter stalks, or why limping appears to come from one head only. What Other Work has Been Done? Whilst many similar experiments have been conducted, this has improved the knowledge of kinesins movement by showing that the inchworm model does not apply. It has opened up avenues for either looking deeper into kinesins movement, or for finding the mechanisms for other motors. The experimental method used was also new, and was different from the previous study by Hua, Chung and Gelles [6], which was researching something similar. Hua, Chung and Gelles looked at the rotations in the movement of kinesin, with the null hypothesis of a symmetric hand-over-hand mechanism. This was done by immobilizing a derivative of Drosophila, and measuring the different orientations of the microtubules as it moved. Their findings were consistent with the inchworm model, which is why it was proposed initially. Conclusion The kinesin mechanism is now better understood than before, with more information gained in explaining the mechanism. This has presented more factors for consideration and created new questions to answer: the opportunity for further research is huge. Future experiments could consider different proteins movements, or look deeper into the kinesin mechanism. The discovery is significant as it has not only given more insight into biological motors, but revealed ample possibilities for more experiments in the field.

Physics of Mining Essay -- physics mining miner

Mining is a necessary component of the world we live in and it has been practiced for thousands of years. The mining industry produces billions of tons of raw product every year. The process of mining is very complicated and involves plenty of physics! Two main components of the mine cycle are: Drilling, and Blasting. Some important factors in mining are the pillars, rock elasticity, and the slope stability of the ground being mined. A basic method for destroying rock is mechanically induced stress, such as drills and erosion jets. A turbine drill for example, uses a turbine to rotate a diamond faced cutter wheel. The power output, p, can be calculated using the equation p=2 Ï€NT where N is the rotational speed of the turbine and T is the torque on the cutter wheel. As the rotary speed increases, the torque decreases. The maximum power output of a turbine drill is when the rotary speed is between 5,000 and 10,000 rev/min. Erosion jets can be classified as low speed or high speed. The low speed jets use abrasive particles, such as sand to erode rock at 10 to 200 m/s and the high speed jets use water at 200 to 1,000 m/s. The high speed jets are used for the hardest rock and require pressures up to 5,000 kg/cm ²! In underground, non coal mining, the excavation of rock is done largely by conventional percussive drills. These break the rock by indentation. The drilling machine applies a force to the drill bit, giving it a velocity which hits the rock and causes it to break. The equation for the peak stress induced by the drill bit on the rock is as follows: ÏÆ' = Ï  cv, where ÏÆ' is the maximum stress induced, and Ï , c, and v are the density, compressional wave length, and velocity of the drill bit, respectively. In coal mining, ... ... Now there is an added force from the water called pore pressure and the normal force is decreased making the slope more likely to fail. The following diagram represents this scenario with 'W' as the gravitational force downward of the upper rock, 'p' as the pore pressure from the water, and 'A' as the area that the water affects. Mines are erected by pillars, which have factors of safety. The factor of safety is the average strength divided by the average stress ratio. When this ration falls below 1.00, there is pillar instability. If one pillar in a mine collapses, the result is greater force acting on the rest which in turn increases their stress and decreases their factors of safety. If all of the pillars are highly stressed, one pillar failure could lead to a domino effect and the collapse of a mine. 1.60 is considered a good factor of safety for pillars.

Health Risks Associated with Technology Essay

The widespread use of technology has led to some important user health concerns. Some of the more common physical health risks are repetitive strain injuries, computer vision syndrome, and muscular pain. These injuries are on the rise of technology. A repetitive strain injury (RSI) is an injury or disorder of the muscles, nerves, tendons, ligaments, and joints. Technology-related RSIs include tendonitis, and carpal tunnel syndrome (CTS). Tendonitis is inflammation of a tendon due to repeated motion or stress on that tendon. CTS is inflammation of the nerve that connects the forearm to the palm. Repeated or forceful bending of the wrist can cause tendonitis or CTS of the wrist. Factors that cause these disorders include prolonged typing or mouse usage and continual shifting between a mouse and keyboard (Jones 45-48). If untreated, these disorders can lead to permanent physical damage. Computer vision syndrome (CVS) affects eyesight. Symptoms of CVS are sore, tired, burning, itching, or dry eyes; blurred or double vision; distance blurred vision after prolonged staring at a display device; headache or sore neck; difficulty shifting focus between a display device and documents; difficulty focusing on a screen image; color fringes or afterimages when looking away from a display device; and increased sensitivity to light. Eyestrain associated with CVS is not thought to have long-term consequences (Anderson and Dean). People who spend their workday using the computer sometimes complain of lower back pain, muscle fatigue, and emotional fatigue. Lower back pain sometimes is caused from poor posture. It is advisable to sit properly in a chair while working and take periodic breaks. Users also should be sure their workplace is designed ergonomically. Ergonomic studies have shown that using the correct type and configuration of chair, keyboard, display device, and work surface helps users work comfortably and efficiently and helps protect their health (Sanchez). Many physical health risks are associated with using technology. These risks include repetitive strain injuries, computer vision syndrome, and muscular pain. Users should take as many preventive measures as possible  to avoid these risks. Works cited Anderson, Cricket Finley and Stacy Anne Dean. â€Å"Computer Pains.† The Medical Update

A person who influeneced me Essay

  When reflecting on personal influences in my life, no one has had a greater impact than my father. He is and always continues to be a positive role model as a father. He always stands by my side, and whenever I fall down, he encourages me to stand up by myself and on my own feet. He has a huge impact on the way I become a person today. He has influenced my life by teaching me the lessons and showing me the right behavior and wrong behaviors In the description of my father. It is evident that language and language diversity plays a large role in critical thinking and expressions. Creative writers have the power to make the ordinary unique and the unique ordinary. My father taught me the most important lesson: how to be a man. I still remembered the day that my father sat next to me and said that â€Å"Listen son, the most important thing to help you become the successful person is your honesty. Never lie to anyone and never lie to yourself†. Read more:  Essay the person I admire is my mother After saying that, he slowly explained the value of honesty. He showed me that every bad situation in the world began with a lie. When a person steals something, he lies to the law, or when a husband cheats on his wife, he lies to his wife. My father often tells me that being a man means facing the truth. I always think back on those words when I get into trouble. My father’s teachings were a cure for my selfishness. He taught me to consider everyone as a part of my family and taught me how to love people by sharing and giving. I believe that the biggest fantasy in life is to buy someone something he really needs and watch his facial expression. From my place I am thankful for everything he taught me. He taught me things that I need or was going to in life. I am what I am because of him and whatever I will achieve in my life will be credited to him. I believe that my father will always be with me even after his soul leaves his body; he will be there through his teachings that I believe are my duty to pass on to my children.

Engineering Essay on From Electric Power Steering to the Airbag System Essays Engineering Essay on From Electric Power Steering to the Airbag System Essay Engineering Essay on From Electric Power Steering to the Airbag System Essay Bosch, Nissan, Toyota, Audi, and Oxford University. [6][7][8][9][10][11][12] As of 2013, three U. S. states have passed laws permitting autonomous cars: Nevada, Florida and California.. Vehicular communication systems Individual vehicles may benefit from information obtained from other vehicles in the vicinity, especially information relating to traffic congestion and safety hazards.Vehicular communication systems use vehicles and roadside units as the communicating nodes in a peer-to-peer network, providing each other with information. As a cooperative approach, vehicular communication systems can allow all cooperating vehicles to be more effective. According to a 2010 study by the National Highway Traffic Safety Administration, vehicular communication systems could help avoid up to 81 percent of all traffic accidents. [82] In 2012, computer scientists at the University of Texas in Austin began developing smart intersections designed for autonomous cars.The intersections will have no traffic lights and no stop signs, instead using computer programs that will communicate directly with each car on the road. [83] Public opinion surveys In a 2011 online survey of 2,006 consumers in the US and the UK conducted by Accenture, 49% of those surveyed said they would be comfortable using a driverless car. [84] According to a 2012 survey of 17,400 vehicle owners conducted by J. D. Power and Associates, 37% of all survey responders initially said they would be interested in purchasing a fully autonomous car. 85] However, that figure dropped to 20% once they learned the technology would cost an additional $3,000. With an additional cost of $3,000, 25% of the male vehicle buyers were willing to pay for a fully autonomous vehicle, while only 14 percent of women wanted the feature. [85] AIRBAG SYSTEM An airbag is a part of the safety restraint system in cars. Airbags are bags that rapidly fill with air when an accident happens. That way they can prevent injuries that occur be cause the driver hit a hard object. An airbag is a useful vehicle safety device.Airbags are used in the world increasingly because in accidents, it can help passengers reduce shock. When the sensor feels a strong shock, the gas device explodes. This gas fills the bag immediately. An airbag, also known as a Supplementary/Secondary Restraint System (SRS) or as an Air Cushion Restraint System (ACRS), is a flexible membrane or envelope, inflatable to contain air or some other gas. Air bags are most commonly used for cushioning, in particular after very rapid inflation in the case of an automobile collision. History of airbagsAn American inventor, Dr. Allen S. Breed, invented and developed a key component for automotive use. Breed Corporation then marketed this innovation first in 1967 to Chrysler. A similar Auto-Ceptor crash-restraint, brandon, developed by Eaton, Yale ;amp; Towne Inc. for Ford was soon offered as an automatic safety system in the USA. The Italian Eaton-Livia company of fered a variant with . The first patent on an inflatable crash-landing device for airplanes was filed during World War II. In the 1980s, the first commercial airbags appeared in automobiles.Since model year 1990, all new cars sold in the United States have been required to have airbags on both driver and passenger sides. To date, statistics show that airbags reduce the risk of dying in a direct frontal crash by about 30 percent. Today, some cars have six or even eight airbags. How airbags work First, moving objects have momentum (the product of the mass and the velocity of an object). If no outside force acts on an object, the object will continue to move at its present speed and direction (because of inertia). Cars consist of several objects, including the vehicle itself, loose objects in the car and, of course, passengers.If these objects are not restrained, they will continue moving at whatever speed the car is traveling at, even if the car is stopped by a collision. Stopping an objects momentum requires force acting over a period of time. When a car crashes, the force required to stop an object is very great because the cars momentum has changed instantly while the passengers has not (there is not much time to work with). The goal of any supplemental restraint system is to help stop the passenger while doing as little damage to him or her as possible.What an airbag wants to do is to slow the passengers speed to zero with little or no damage. The constraints that it has to work within are huge. The airbag has the space between the passenger and the steering wheel or dashboard and a fraction of a second to work with. Even that tiny amount of space and time is valuable, however, if the system can slow the passenger evenly rather than forcing an abrupt halt to his or her motion. Motorcycle airbag In 2006 the airbag was set up for a motorcycle. This was in the Gold Wing by Honda. 1] Air bags supplement the safety belt by reducing the chance that the occupants h ead and upper body will strike some part of the vehicles interior. They also help reduce the risk of serious injury by distributing crash forces more evenly across the occupants body. One recent study concluded that as many as 6,000 lives have been saved as a result of airbags. However, the exact number of lives saved is almost impossible to calculate. SPECIAL VEHICLES (EARTH MOVERS/ EXCAVATORS) Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform (known as the house).The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fun damentally different from cable-operated excavators.Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform (known as the house).

All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators. Configurations Excavators come in a wide variety of sizes. The smaller ones are called mini or compact excavators. Caterpillars smallest mini-excavator weighs 2,060 pounds (930Â  kg) and has 13 hp; their largest model is the largest excavator available (a record previously held by the Orenstei n ;amp; Koppel RH400) the CAT 6090, it weighs in excess of 2,160,510 pounds (979,990Â  kg), has 4500Â  hp and has a bucket size of around 52. m? depending on bucket fitted. Engines in excavators drive hydraulic pumps; there are usually 3 pumps: the two main pumps are for supplying oil at high pressure (up to 5000 psi) for the rams, swing motor, track motors, and accessories, and the third is a lower pressure (700 psi) pump for Pilot Control, this circuit used for the control of the spool valves, this allows for a reduced effort required when operating the controls. The two main sections of an excavator are the undercarriage and the house.The undercarriage includes the blade (if fitted), tracks, track frame, and final drives, which have a hydraulic motor and gearing providing the drive to the individual tracks, and the house includes the operator cab, counterweight, engine, fuel and hydraulic oil tanks. The house attaches to the undercarriage by way of a center pin, allowing the ma chine to slew 360Â ° unhindered. The main boom attaches to the house, and can be one of several different configurations: * Most are mono booms: these have no movement apart from straight up and down. Some others have a knuckle boom which can also move left and right in line with the machine. * Another option is a hinge at the base of the boom allowing it to hydraulically pivot up to 180Â ° independent to the house; however, this is generally available only to compact excavators. * There are also triple-articulated booms (TAB). Attached to the end of the boom is the stick (or dipper arm). The stick provides the digging force needed to pull the bucket through the ground. The stick length is optional depending whether reach (longer stick) or break-out power (shorter stick) is required.On the end of the stick is usually a bucket. A wide, large capacity (mud) bucket with a straight cutting edge is used for cleanup and levelling or where the material to be dug is soft, and teeth are no t required. A general purpose (GP) bucket is generally smaller, stronger, and has hardened side cutters and teeth used to break through hard ground and rocks. Buckets have numerous shapes and sizes for various applications. There are also many other attachments which are available to be attached to the excavator for boring, ripping, crushing, cutting, lifting, etc.Before the 1990s, all excavators had a long or conventional counterweight that hung off the rear of the machine to provide more digging force and lifting capacity. This became a nuisance when working in confined areas. In 1993 Yanmar launched the worlds first Zero Tail Swing excavator,[2] which allows the counterweight to stay inside the width of the tracks as it slews, thus being safer and more user friendly when used in a confined space. This type of machine is now widely used throughout the world.There are two main types of Control configuration generally use in excavators to control the boom and bucket, both of which s pread the four main digging controls between two x-y joysticks. This allows a skilled operator to control all four functions simultaneously. The most popular configuration in the US is the SAE controls configuration while in other parts of the world, the ISO control configuration is more common. Some manufacturers such as Takeuchi have switches that allow the operator to select which control configuration to use. Excavator attachmentsHydraulic excavator capabilities have expanded far beyond excavation tasks with buckets. With the advent of hydraulic-powered attachments such as a breaker, a grapple or an auger, the excavator is frequently used in many applications other than excavation. Many excavators feature a quick coupler for simplified attachment mounting, increasing the machines utilization on the jobsite. Excavators are usually employed together with loaders and bulldozers. Most wheeled, compact and some medium-sized (11 to 18-tonne) excavators have a backfill (or dozer) blade .This is a horizontal bulldozer-like blade attached to the undercarriage and is used for levelling and pushing removed material back into a hole COLLISION AVOIDANCE SYSTEMS A considerable amount of research is addressing eSafety systems of the future. Much work is being carried out on technologies such as collision avoidance systems but their usefulness in addressing high-risk crash scenarios typical of most European roads as well as their feasibility has yet to be determined.Research on collision warning and collision avoidance systems is taking place in Japan, the United States and in the European Union within the European Commissions eSafety programme. Very large estimates of the safety potential of such systems have been claimed following laboratory studies, but the range of technical and behavioural issues involved in many of the concepts require full on-road assessment. To be practical, most of the proposed systems require a well controlled traffic situation, such as that foun d on motorways, but where the casualty reduction potential is relatively low.For an overview of key issues [41]OECD, 2003 Road safety: impact of new technologies. Various systems are under development: Forward Collision Warning Is a system which comprises a visual and audible warning that the driver is too close to the vehicle in front. The warning depends on how long the distance is between the vehicle and the vehicle ahead. The level of warning changes from safe to critical as the following distance decreases. The Reverse Collision Warning System Is a visual and audible system which warns drivers about the likelihood of collision with an object behind the vehicle by means of sensors in the rear bumper.The warning intensifies when the distance between the vehicles rear and the object decreases. Adaptive Cruise Control (ACC) Enhances automatic cruise control found in many new vehicles by automatically maintaining a set following distance to the vehicle in front. The distance to the preceding vehicle is measured by radar, laser systems or both. When the speed of the vehicle in front is slower than the adjusted speed, the ACC system adjusts vehicle speed to allow a safe distance to the lead vehicle. Collision Mitigation by brakingIs an evolution of ACC with the addition of a braking system that increases headway by braking; these systems may also detect obstacles within the road and brake accordingly. The speed and separation distance at which the systems operate is determined by the arrangement and type of sensors and the recognition ability of the systems. Lane-Keeping Devices Are electronic warning systems that are activated if the vehicle is about to veer off the lane or the road. Times to collision in safety-critical lane changes are normally much less than one second.Since mean driver reaction time is about one second, there is not sufficient time for a driver to respond to a warning before crashing. Because there is insufficient time for reaction to a war ning, lane change and merging crashes can probably only be avoided by intervening systems. But these have their own problems: how to detect driver intentions and how to intervene. This may be by taking over the steering from the driver or by providing feedback through the steering wheel. The technical and operational feasibility of such systems has still to be demonstrated. Most existing systems are warning only systems.

The Sociology of Religion Childhood Indoctrination

The Sociology of Religion Childhood Indoctrination Childhood indoctrination is one of the ways how one become religious where people are brought up and grow old while still in a given religion and always believe it. This becomes difficult to overcome because people are born and told that a certain religion is the true one making it difficult for them to question it, fail to accept it or believe it is a lie.Advertising We will write a custom essay sample on The Sociology of Religion: Childhood Indoctrination specifically for you for only $16.05 $11/page Learn More The parents cannot be blamed because their main intention is to show the truth and they grew up the same way. This becomes like a circle that has no end, which is passed down from one generation to the other until someone reveals that it is not the truth. Fear makes people become religious and fail to question the religion. When people think about death they are afraid because they do not know what will happen to them after they die. The religious p eople tell them to believe in a certain religion so that they do not go to hell forever. When they believe that these people are telling the truth they fear the punishment that would follow if they do not believe. Many people cry and pray for forgiveness when they are very sick due to the fear of death. If there were no fear, people would question what they are told as the truth before they believe it. (Davie 62) People become religious when they are desperate and in need. They believe in what they are told due to lack of anything else, lack of hope and nothing to hold on. In a situation where one is satisfied completely then religion would not be significant since people would be contented with what they have as well as the way they are. In addition, people accept religion as a tradition that would be accepted for many years. The great grandparents followed the religion and therefore people follow it too. For example, the people who are born in the United States of America are like ly to be Christians while Muslims are from the Middle East. The people have many questions without answers and therefore become religious to search for answers. There are questions without answers and no one attempts to answer them while religious people leave them unanswered. When people make bad decisions, they feel guilty and fail to forgive themselves and therefore turn to God who forgives them so that they feel better. Their sins haunt them and believe that they may be punished for their deeds (Davie 49)Advertising Looking for essay on social sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More Many people believe that it is only in the church that they can get a chance to socialize with others. Their main aim is not to attend the church service but interact with others and have a sense of belonging. They get the comfort they desire as well as assurance, which make them feel safe when they know that everything is all right . They remain in the religion when they think that they would have chaotic life if they stay without a religion. Many religious people are not responsible and need God so that they can be taking all their problems to him. For example, those who smoke or drink believe that they cannot stop smoking alone and put their faith in God to do everything and help them live a righteous life. People become religious for spiritual fulfillment in order for their life to have meaning. This makes them turn to religion for the spiritual void to be satisfied and live a comfortable life. People go to church and when they find others being exited, they believe that is what they require and that nothing can worry them (Davie 53) There are dogmas and beliefs in religion that are accepted and the followers are expected not to question about them. When other beliefs are available there can arise intolerance as well as inflexibility because no one is allowed to compromise the word of God. When the scriptur es are allowed to be interpreted and the interpretation is correct, it becomes difficult to solve any conflict that arises when people doubt it. The only person who is the winner is the one that will have most followers who are motivated through action. The extremists of religion who apply radical measures to fulfill the wishes of God bring about the conflict of escalation. When there is a conflict between what is evil and good, it becomes difficult to compromise by accepting the devil (Davie 27) Religious conflict can arise when evangelism has different strains. Some people may come together and not allow other religions the right to practice their own faith. They do this in order to minimize their beliefs because they feel that the religion may be dominant. For example, Christianity was suppressed in China where the government thought that it was dangerous and rival of loyalties of the citizens. The media emphasize on the negative effects of religion, which leads to hostility, as well as fear to the believers. The media do so by confusing people instead of informing them through misunderstanding the goals of different religious groups.Advertising We will write a custom essay sample on The Sociology of Religion: Childhood Indoctrination specifically for you for only $16.05 $11/page Learn More The difference in religions is a potential source of conflict because people ignore other faiths. The religious group that is less popular is under tension compared to the most popular and privileged. When it happens that the group that is most popular is the minority it becomes easier to have a conflict with them and understanding becomes difficult. When crisis arise, members involved rely on extremists to provide solution. The identities of the group members can be shaped when compared to others, which makes the faith of one religion threatened by the other. Religious conflicts arise because the mind of people is unique and has different exper iences. These different individuals are located at different places where they associate with others with different experiences concerning their religion. When these characteristics are combined conflicts often arise in the course of their relationships. Hinduism has been reformed many times since it started due to conflicts when the caste system that was hereditary was rejected. Nanak emphasized that Muslims and Hindu should tolerate one another when he declared that similar God was worshipped. He could not be tolerated by the two religions, which made a new religion to be started. There serious conflict between the apostles of John and Jesus was about baptism. Those who followed Jesus were supposed to pay a price through baptism to be accepted by those who followed John. Peacemakers have been solving religious conflicts whenever they arise because they are complex. The people should be informed about the wishes of God in different religions so that they can avoid evil and do well (Davie 34) Davie, G. The Sociology of Religion.

Never share this information at work

Never share this information at work Networking is what gets you in the door, but building real relationships with coworkers is what keeps you there and earns you respect. And you can’t really connect to people- even colleagues- if you don’t open up and share every once in a while. But sometimes the bonding goes too far. When sharing becomes oversharing, you can erode any credibility you’ve built up in a workplace. Here are a few things smart and successful people make a rule of never  bringing up in the workplace.How much you hate your coworkersNo matter how terrible Bob in Sales is at his job, it’s not something you can talk about with your coworkers- even your friends. Unless you’re talking to your best non-work friends or your partner, there’s no cause to broadcast someone’s ineptitude. Be kind. Take the high road. And for that matter, don’t smack talk about your boss or how much you hate your job either.PoliticsBy far the easiest way to alienate someone is t o casually discuss politics. Things are quite simply too fraught these days. A haphazard comment here or there could really lose you points. In general, it’s best not to mix office and politics in general- tense times or not. You never know where someone (or the cubemate quietly listening) stands. If others are talking politics, listen and smile and step outside.  How much you makeEven if you’re sharing your salary to commiserate with other low-level earners, you never know what those people might be making. It could be even less than you. Don’t run the risk of humblebragging. And definitely don’t outright brag. First of all, nobody cares. Second, they’ll just assume you’re a materialistic jerk.Your sex life†¦ or anybody else’sReally, there’s no reason to divulge any details about what goes on in your bedroom. Or worse- to speculate about what might or might not go on in someone else’s. It’s just gossip, wh ich is never a good idea. Plus, it’s likely against company policy. You just never know when you might make someone feel uncomfortable, so respect work and personal boundaries.Your ongoing job huntIf you’re job hunting because you’ve outgrown your position or you just plain hate your job, that’s fine. Keep it on the DL. Nobody wants to be friends with the kid who doesn’t even want to be on the playground with the other kids.Your online presenceUnless you become actual friends with a coworker, it’s best to keep your social media networks separate. LinkedIn is great for work friends, but keep your Facebook and Twitter and Instagram to people who won’t be annoyed by your vacation photos of margaritas and tequila shots.Offensive jokesAgain, anything off-color is probably going to get you in trouble with your human resources department. If you have a racist, misogynist, or intolerant joke in your pocket, do yourself a favor and keep it to yourself. You  will offend someone and people  will think less of you. Is it really worth the forced laughter?Your dreams of a promotionIt’s fine to covet rungs above yours on the ladder. It’s not fine to tell people that you’re out to unseat your coworker or your boss. The news will definitely get back to that person, ruining a relationship for good. And whether or not you get your way, you won’t have the respect of everyone around you.Personal dramaYou might be having problems at home, or in your relationship, or with your health. Save intensely personal tales for your besties and your therapist. At the very least, save them for lunch hour with one or two close work friends, not your water cooler buddy. Work is not the place to be blabbing about your issues and emotions- it’s a professional setting, no matter how casual the office and how kind the people.

Project Management Review Assignment Example | Topics and Well Written Essays - 750 words

Project Management Review - Assignment Example This structure helps in creating a framework and provides guidance in terms of schedule development and control. The process of defining the project consists of five steps 1. Defining the project scope: - A project scope is the end result of the project, i.e. a product or service for the client or customer. The scope clearly explains the measurable and tangible result delivered to the end user. 2. Establishing project priorities: - The second step is to establish the project priorities, which determines the shifts in the comparative importance of criterions connected to cost, time, and performance parameters. This also helps in managing the priorities of project trade-offs and in formulating the parameter requirements. 3. The third step involved in defining a project is to create the Work Breakdown Structure. A work breakdown structure is the hierarchal sketch that categorizes the products and work elements engaged in a project. 4. Integration of Work Breakdown Structure with the Org anization is the fourth step of defining a project. The ability of the firm to discharge its work responsibility towards a project is determined at this stage. This is where WBS and the OBS (Organizational Breakdown structure) are integrated. 5. The final stage of the process is coding the Work Breakdown Structure for the information System. At this stage, a range of essentials of the WBS are identified and defined. Reports on the organizational fundamentals, work package, budget and cost are consolidated at all levels of the organizational structure. Lag and Slack According to Francis and Horine (2003), in a series of linked tasks, lag means the ‘delay’ between the linked tasks; and it is necessary to use lag in a network as it is essential for the smooth progress of tasks (p. 80). The lag can be described as a ‘planned delay’. On the other hand, slack explains the extent of time that a task can be belated without affecting its successor tasks. As Chapman (2006, p. 9.22), Gantt chart is prepared to break a large project into a sequence of smaller tasks in an organized way. This chart describes when each task should start and how long it would take. On the other hand, a network diagram is a tool used for demonstrating how the impacts of a project are related and what the consequences of the impact are. Diagrams summarize a large portion of the project body as it is represented as graphical representation. Backward pass: A backward pass is a device used in the project management. It refers to the estimation of late start dates and late finish dates regarding the section of activities that have not been completed. This is calculated using by referring back through the schedule network from the end date of project segment. The end date may be determined by the client or by the supervisor using the forward pass. A backward pass determines the late start date and late finish dates. Scope statement: The project is on arranging a dinner-danc e concert for a local charity. It is going to take place in a four weeks’ time. This concert is reserved specially for 30 couples and the amount collected at this concert goes directly to the needy segment of the local society. The first step involved in the project is to create work breakdown statement of the project scope. The different elements of the project are to be distinguished at first hand. It is easier to understand the different

Policy Process Paper Essay Example | Topics and Well Written Essays - 750 words - 1

Policy Process Paper - Essay Example To improve the operations of a criminal justice system, some strategies need implementation. First, some reforms must be made in the re-entry programme. Released prisoners face a lot of challenges that trigger them to their return to criminal activity, to address the above challenges I would recommend the re-entry services that may help reduce barriers to obtaining employment, housing, or other services that reduce the chances that a person commits a new offense while out of prison. I would suggest a partnership with the faith based community organizations whereby majority of released inmates will return (Roberts, 2003). Secondly, rehabilitation is another key issue to be tackled. Rehabilitation majorly revolves around job skills, counseling and education (Crawford, 2001). Up to date, many ex-convicts still leave prison merely better-educated and skilled criminals (Mears, 2006). Hence, I recommend the use of probation officers to do the rehabilitation for some selected groups of sentenced offenders. With the prior aim set to high risk offenders. I also recommend the partnership with the NGO sector. They will collaborate with the probation officers mentioned. Thirdly police officers also form an integral system of criminal justice and foremost police reforms should be done. These will achieve the objective of improving public organisation, reduction in the levels of and promotion of the human rights. According to Roleff (2003), improving the reform process in police, expanding the standards of safety and investigation, ensuring transparency in the police sector as well as bringing police work in line with international standards will assist in meeting above objectives. According to Garside (2004), with regard to the length of sentences, sentencing options and length of prison terms under the current Criminal Code of the country should be revised to consider the modern trends in the

The French Revolution in Russian Intellectual Life Article

The French Revolution in Russian Intellectual Life - Article Example In 1905, Russia was defeated by Japanese and following the same year there was the peaceful parade of workers in St. Petersburg (later known as Petrograd) was open fired by Tsarist troops. Following the general strike, Tsar created first Russian constitution and the State Duma, an elected parliamentary body. But Nicholas always wanted to retain autocracy. (S?lapentoch, 2008).   During World War I, Russia suffered great losses and had millions of causalities. Nicholas then went to take control of the army himself in 1915, but at that time there were no such trained people nor any supplies of arm left to fight. This World War I period proved to be a great blow to Tsar’s rule. (St. Petersburg life) On 23rd February 1917, the festival of International Women’s Day broke out in a protest in the streets of St. Petersburg (Russian Capital), against the food shortage. Gradually everybody joined the strike including men, students, and all working classes. Even military forces t urned rebellious against Tsar and shot their own military officers when they asked the forces to shot the people in procession on the orders of Nicholas. This is known as the February Revolution. (St. Petersburg life) With so much unrest prevailing finally Nicholas and tried to hand over his powers to his brother Michael but he cannot become leader until he was elected via elections. The Provisional Government was temporarily formed by the members of Duma until the elections held. Also, a Petrograd Soviet Organization came into being by the trade union of workers and soldiers who favored Socialism than democratic reforms. (St. Petersburg life) In 1917, Lenin decided to return to Russian as he got a chance to rule Russia. Lenin was against the Tsar rule and was under arrest during his reign but now he got a chance to lead his party, Bolsheviks. He entered by the permission of German authorities as they have won the war and Russia was under control. Lenin was welcomed by Russians and after getting the control over powers, he immediately condemns the Petrograd Soviet and Provisional Government and tried to introduced Communism. In summers of 1917, Lenin tried to bring another revolution by overthrowing Provisional and Petrograd Government but was not succeeded as Kerensky, one of the important figures of Petrograd and Provisional Government condemns it and troops were arrived in the city suppressing the dissidents and accused Bolsheviks of being in collision with Germans. Lenin escaped to Finland and others were arrested. Lenin didn’t stop and continued his planning. It was not too late when Kerensky had to face political setbacks and somehow he had to contact Bolsheviks for military assistance when he feared Kornilov was aiming for military dictatorship. The Bolsheviks aided him and hence, took the powers by winning majority votes within the Petrograd and Moscow Soviet. At last, Leon Trotsky was elected as the president. In October of 1917, Lenin now fina lly decided to capitalize his party’s popularity by replacing the Provisional Government with Bolsheviks. On 24th October, the troops entered St. Petersburg capturing all major buildings and positions in the city.

Discuss some of the historical,social,economic and political reasons Research Paper

Discuss some of the historical,social,economic and political reasons many Quebecois support the notion of the separate state fro - Research Paper Example For the purpose of this research, the cultural, political, economic and social causes shall be discussed individually. There are many reasons why it is important to study the issue at hand. First, the study shall be conducted so as to enlighten the Canadian people of the Quebecois struggle for identity within their society. Notably, Quebec is the only place in Canada which uses French as its primary language. It is the sole Canadian province in which most of the residents speak French. In fact, of the seven million people living in Quebec, about eighty percent (80%) of its population speaks French based on the demolinguistic data provided by the Office of the Commissioner of Official Languages (â€Å"Statistics,† 2007). This means that majority of its people have French ancestry (Croats, 2002). Montreal, a city in Quebec is actually the world's "second largest French-speaking city" (Croats, 2002). According to Rennay Croats (2002, p. 22), Quebec is a home to many French Canadi ans who descended from the original French occupants of the sixteen hundreds (1600s) and seventeen hundreds (1700s). In this context, it can be observed that Quebec is quite different from the other provinces in Canada. The difference is substantially cultural. In comparison with the other Canadian provinces, Quebec is primarily a French-speaking society. The other provinces use English as their official language of communication. By simply knowing these facts, one could somehow understand why to an extent an ethnic struggle is happening within the Canadian society. Language is actually part of a culture. It makes a certain group of people unique from the others. It creates an identity. In this sense, it is also relevant to study the controversy for everyone to understand the relationship between language and ethnicity. It is contended that the two are interrelated. The third and last reason for this research endeavor is to provide a possible solution to the Canadian societal confli ct. The main topic of the research paper shall have four subtopics. The subdivision shall be composed of the following ideas: Quebecois Culture vs. Canadian Culture, Political Developments, Economic Influence and Social Differences. First and foremost, the paper will compare the Quebecois culture to the culture of the rest of Canada. This is to be done so as to arrive at the most comprehensive analysis of their cultural differences. Comparison actually provides a foundation for formulating statements with regard to empirical regularities and for interpreting as well as evaluating situations relative to theoretical and substantive criteria (Ragin, 1989). The comparative method of research is concerned with cross-societal similarities and differences (Ragin, 1989). Significantly, this comparison shall also tackle some historical accounts to know the origin of their cultures. Historical data are most of the time effective in exposing ethnic differences. As cited by Kenneth Bailey (1994 ), historical research can be "an effective complement to generalized scientific research" through the documentation of particular historical event. Second, the paper will investigate the political issues which are related to the separatist movement of the Quebecois. It is actually claimed that the recent political developments in Canada have contributed to the Quebecois move for independence. These political developments are actually centered on the evolution of two Canadian laws, the Canada Act of

Enterprise and Entrepreneurial Management Assignment - 1

Enterprise and Entrepreneurial Management - Assignment Example Most companies aim to make a business plan as it helps them in attaining stability and growth. Critical appraisal of the business planning process The business planning process itself has a lot of obstacles and this is one of the reasons many organizations do not make any business plans. These organizations in fact rely on the experience of entrepreneurs and top executives. Let us find out the obstacles faced in the business planning process. Idea generation The first step in a business planning process is to document which product or service the firm wants to sell. It is very relevant to find out and be clear on a business idea. Unfortunately, most business ideas may be implemented. This is because the top executives may not have conducted appropriate research on the customer market before coming out with a business idea. Another problem which individuals may face is the financial constraint. Most business ideas may not receive adequate financial funding. There are several problems which may lead to the failure of the idea. One is that the individuals who wish to launch a new product or service may lack the required skill and competence required, makes hurried decisions without making a thorough analysis of the consumer market or may be ignorant about what is to be done. Hence, most product or service ideas may miserably fail (Flint, 2002). ... These objectives need to be formulated in order to chalk out a path to attaining success. Individuals need to emphasize on certain aspects before formulating strategic objectives. These are monitoring alternatives solutions, future trends need to be predicted, problem areas need to be avoided and fixing both short term and long term goals (Ramanujam, Venkatraman & Camillus 1986). However, most planners may not be able to plan these objectives properly. This is because the above mentioned aspects need a lot of attention and lack of thorough research into these aspects may lead to wrong setting of goals. At times, the top management may set up unrealistic and unattainable goals. Market research and analysis Market research and analysis is a thorough analysis of the customer market and also seeks to find out the opportunities, strengths, weaknesses and threats. All in all in seeks to understand the product or the service market. All these aspects need to be researched in order to develo p a thorough understanding of the customer’s needs and accordingly develop specific abilities and investment required for the necessary resources. Sometimes, lack of thorough product or service market understanding, may lead to the focus on the line of product or service be either too broad or too narrow (Slater & Olson 2001). Also the specifications relating to the performance of the product or service, the prices, and the complementary product or service line may affect market analysis and research. If any of these aspects, have not been thoroughly researched then it may lead to severe problem in the implementation of the business plan. According to

Public Policy and Law Essay Example | Topics and Well Written Essays - 3000 words

Public Policy and Law - Essay Example The Equal Employment Opportunity Commission (EEOC) has discovered several major weaknesses in the anti-harassment policies and processes in many agencies. This essay discusses the definition of sexual harassment, as well as the relevant laws, case laws, and the current figures and scenarios. Introduction Cases of sexual harassment in the workplace is well documented and widely known. Catharine MacKinnon led the campaign for sexual harassment to be acknowledged as a rightful issue under the 1964 Civil Rights Act’s sex discrimination requirements (Mink 64). Before sexual harassment was acknowledged by the U.S. Supreme Court as a valid type of sex discrimination forbidden by federal law in its resolution in Meritor Savings Bank v Vinson in 1986, numerous lower courts had wrestled with the difficult problems posed by sexual harassment (Mink 64). Numerous lower courts had declined to acknowledge sexual harassment as a valid ‘cause of action’, claiming that courts shoul d not investigate or examine explanations of human conduct in the workplace. Human conduct or behavior, according to these courts, embodied a ‘slippery slope’ that would require a much larger number of federal judges, or that it would dramatically increase the number of court cases (Achampong ix). The invalidation of these decisions was an acknowledgment of the reality that sexual harassment is a criminal conduct that brings about a valid cause of action. Definitions, Relevant Laws, and Case Laws The 1990s have witnessed a sharpened awareness in society about sexual harassment, and a persistent, very important move toward total prevention of sexual harassment in the workplace (Bakirci 17). However, there is no direct and simple definition for sexual harassment. However, any definition in any policy should be clear and straightforward without leaving out the key legal principles (Orlov & Roumell 61): Sexual harassment is against the law. Any conduct of a sexual nature wi th or between coworkers or other managers could be considered sexual harassment. Anyone who breaks the law will be punished. All policies pertaining to sexual harassment must explicitly define that sexual harassment is a type of sexual discrimination prohibited by Title VII of the 1964 Civil Rights Act or federal employment discrimination laws and nearly all other anti-discrimination laws. The policies of the Equal Employment Opportunity Commission (EEOC) policies sexual harassment must be used. Most companies integrate them into their guidelines because they provide a quite precise and definite legal description of sexual harassment. The EEOC defines sexual harassment in this way (Achampong 201): Unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature constitutes sexual harassment when (1) submission to such conduct is made either explicitly or implicitly a term or condition of an individual’s employment, (2) submission to or rejection of such conduct by an individual is used as the basis for employment decisions affecting such individuals, or (3) such conduct has the purpose or effect of unreasonably interfering with an individual’s work performance or creating an intimidating, hostile, or offensive work environment. Nevertheless, any definition of sexual harassment must not end with the EEOC policies. They are simply the basis for a definite and brief definition. The various forms of sexual harassm

How Technology Changed Design Process

How Technology Changed Design Process Consider for a moment the argument of good vs. evil. Neither can seem ably exist alone, without the other surfacing or breaking the mould at one time or another. Now consider the historical friction between the arts crafts era of design and todays computer aided magnificence. As soon as design aids such as AutoCAD, and laser cutters were created, people began to argue for the loss of design origins and individuality; some may even say its soul and character. Those who were enticed by this new technology that allowed production to be executed in half the time on twice the scale, were in awe, and naturally as with all two sided battles, alliances were formed. Gone are the days of hand carving and endlessly tiring man hours in workshops shouted the people of the future, what takes you a week and four men, takes us a day with a computer, with no need for getting grubby. The conceptual age of design was truly revolutionized by computers, no argument there, but was it necessarily a good thing? No! shouted the people of tradition, where you exceed us in production you lack in character, where is the heart and soul? The attention to detail absorbed through precise workmanship and craft? (Pemble, 2010) Once again I feel that their argument is sound, but is it not also a prime case of people fearing what they do not understand? As is the case with all arguments, it often takes a step back and a good long look at both sides of the case to induce or create a compromise that allows both sides to advance further than they imagined. For this we need to begin in Weimar, Germany, the year is 1919 and the Bauhaus school of Art design is formed. Throughout Europe, world war one had clearly left its mark. The German state lay in disarray and its economy lay in tatters and after the initial turmoil over the future of Germany. Whether it be soviet communist or capitalist German, several factors were set in stone, the way of imperialist grandeur and ornamentalism design had to change, the transformation of emotional Expressionism to the matter-of-fact New Objectivity (Minusfive 2006). This gave the German organisation, Deutscher Werkbund, founded in 1907 and considered the forerunner to the Bauhaus, a newfound vessel for their visions of design. The Werkbunds aim was: to harness the new potentials of mass production, with a mind towards preserving Germanys economic competitiveness (MinusFive 2006). This kind of agenda for change become apparent in many areas of design, it may have originated in architecture, with the Werkbunds idea of economical production for housing and the built environment, but it spread to even the most men ial of objects, combining industrial methods with artistic flair, an example I suppose being envelopes. Up until 1840 all envelopes were handmade, cut from paper and constructed before being used to send mail. However, in that year a British man George Wilson derived a method of mass production from the geometric layout called tessellation. This enabled multiple envelopes to be cut simultaneously minimising the waste cut paper. Only five years later the production of envelopes was revolutionized further by two men, Edwin Hill and Warren De La Rue, whom pioneered a steam pressing machine that enabled the cutting, folding and gumming process of envelopes all to be done in one stage. As was to happen less than a century later to various crafts, the traditional method of production died slowly at first, then all together outclassed and outperformed by its machine age successor. Here is where the compromise between industrial and traditional methods is required. During my journey in which I created my own envelope design, I was able to see the merits and disadvantages of both ends of the spectrum. The first step was to take a standard sized envelope and dissect, analyse, and recreate it, several times, to get the feel for and a thorough understanding of its design. I then, from a purely conceptual view, came up with my design, which was to be a clasp sealing disc shaped envelope. I then repeated the process i used for an existing design, for my own, entailing technical drawings, models, prototypes, and experimentations, until I came up with my finalised design. Here is where the best of both worlds comes into its own. If I were to embark on this project in an identical fashion, but in a 3D virtual computer world via programs such as CAD and 3DSMax, it would be quicker; however there would be no feel for the design, certainly no character, and there would be no way of knowing if it worked, or how it were to assemble. Tactility is one of the charms of handmade works. It was at this point that I was encouraged to investigate the more industrial side of production, so after transferring my design from hand drawn plans to an AutoCAD design, It was then onto the laser cutter, which essentially is a robotic device that reads the lines, line weights, and colours of lines to determine where needs to be cut or scored on the material placed under the laser. Now here comes the difficult part, but does prove to be the part that pays off, as the laser cutter is undeniably fiddly to setup and calibrate with regards line weights, fold lines and cuts. In this sense, there is still no smooth transition between man and machine, as it took several attempts for the laser cutter to understand the design, however that said, once calibrated it is the perfect tool for recreating a single design on a mass production level. Modern methods have thankfully taken the stress and immense man hours required out of hand production and tradition, but the integration and principles of tradition and good design should never become fully digitalised like its successor. Just like the argument of analogue vs. digital regarding timepieces, each will have their role as one simply wouldnt exist were it not for the original. The point of this investigation for me is that both modern and traditional crafts both have their roles, and as many influential figures agree, neither should be neglected nor overlooked, for they both hold merits. Technology has indeed renovated the design world, but in todays society it does on occasion overpower and fail to do itself justice, leaving the piece cold, generic and grey, failing to do itself justice. This as with most aspects of the design world boils back down to the roots of the Bauhaus. Take for instance the idea of Bauhaus furniture design, it wanted to maintain the traditions of soul in design, along with logic, so for instance a better thought out design made with more economic materials and technologies, but still manually overseen or produced would therefore potentially be the perfect design formula. Enter Mies Van Der Rohe. Originally from Aachen, he moved to Berlin in 1905. At the age of 19, he was unqualified and spent his time hopping between building sites. Not exactly the start in life most would stereotypically associate with a famous architect, whom set about change we feel the benefits of today. The tasks of design and construction were combined in his early education, not separated by increasingly common divisions between architect and builder. (Zimmerman C. 2006, p.7) Mies van Der Rohe was trained as an accomplished bricklayer and stonemason under apprenticeship of his father, but also trained as a proficient draftsman, after taking a keen interest in design whilst he worked for a specialized plasterwork company. He saw the need for an understanding of both the ends of the construction spectrum from the initial spark of an idea, to the laying of foundations, so that he may design more efficiently. Riehl House was his first commission under recommendation of a colleague at Bruno Paul architects, and was finished in 1907. The young Mies proved himself able to design and build competently, even skilfully, and capable of productively engaging the most contemporary issues of the architectural world in Berlin at the time. (Zimmerman C. 2006 p.19) This was only the beginning of a long and fruitful career for Mies, and this subliminal theme was present throughout his career, the breakaway from tradition and supposed acceptable form, in favour of modular, efficient modern materials in design. This ability to draw and recollect from the design ethos of yesteryear, and combine it with the forefront of technology to create something that is not only perfected in its balance, but also pleases a wider audience is an ability he seldom neglected. A prime example is of this is dark red masonry built Lange and Esters House. The esters and Lange buildings were both surfaced in dark brick; but they are only partially bearing-wall structures. They were among the first modern buildings to free brick from its load bearing function. (Zimmerman C. 2006 p.33) It gives the appearance of a traditionally built house of the time, yet modernised in aesthetics slightly, and due to its modular skeleton of steel it allows the large open views that it contains, and for the first time in German architectural history, the spatial design dictated the structural calculations. Just like with his most prolific of projects like the Seagram building, IIT centre and exhibition hall in Berlin (ironically his career peaked both as he left and later returned to the city) he used the most modern of approaches to construct the building yet he still remained true to the classical ideals of open flowing space, secular views, and the overall mastery of the space provided. I suppose a pinnacle case study would be that of the Barcelona Pavilion. After being accepted into the Werkbund in 1927, Mies was commissioned by the German Reich to design and build the 1928 World exhibition in Barcelona. With its beautiful classical onyx and marble walling, and chrome framed glass facades of multiple shades, it was the epitome of form with function, a piece de resistance of the Bauhaus vision. Instead of the normal layout of conventional housing or building, it followed Mies combination of Rhythmic movement and carefully composed views. (Zimmerman C. 2006 p.39) Though beautiful, like all individual prototypes it was slightly flawed (due to insufficient budget and lack of specialised materials, the prolific flat roof was susceptible to water damage and nearly ruined the entire structure), but just like the method of trial and error in many of the hand crafts, Mies learnt from his mistakes, and embraced them with his future projects, like the Seagram building and IIT, whereby he perfected his steel frame designs that have revolutionized todays construction. The Seagram building was undoubtedly in this paradigmatic fashion. It is often seen as the finest high-rise building Mies ever built. No longer looking back to past historical design for legitimation, the building presents the architecture of capitalism with its most essential, concentrated face. (Zimmerman C. 2006 p.16) Just like in my investigation into envelope design, sometimes things can be flawed; the important part is learning from it and being able to continue. This is where I feel that by doing all of the experimenting stage by hand, with copious amounts of trial and error, I managed to succeed in a design that as viewed by others was vitally flawed, my point being this. The initial design criteria given to me was that the envelope had to be capable of holding this essay and any accompanying notes, drawings, work etc and my design being circular was therefore flawed, considering all of my notes and work is on rectangular pieces of paper. It may seem like a very simple answer to a glaring omission, but I have simply decided to enlarge the size of the envelope, and changed its own criteria in that it will be more like a folder, capable of holding my work. Just as alterations were needed to my envelope, drastic alterations were needed to the world of design. The winds had changed direction, and change was coming. As with a lot of the architects of the time and followers of the Neues Bauen, people frowned upon this new rationale of design. By 1933 many architects of Neues Bauen understood their precarious status in national socialist Germany, and many emigrated. (Zimmerman C. 2006 p.14) With the tension growing rapidly in Germany, and the intolerance of the now empowering Nazi party quickly showing itself, the design world soon became a focal point. With its grand imperialist nature, the new Reich wanted its capital to show this. However tradition ruled the waves. As soon as the National socialist party came to power the Bauhaus was voluntarily closed by its members, knowing the view of the new Reich and how its left wing ideals would be dealt with. Nazi writers like Wilhelm Frick and Alfred Rosenberg had labelled the Bauhaus un-German and criticized its modernist styles (MinusFive 2006) Many architects of the time soon began to emigrate, restrictions upon Mies own work was imposed and his security was soon threatened. In 1938 he made a career changing choice and emigrated to the United States of America. Here I feel began the true nature of ingenious design. By that I mean the ability to cover the entire spectra, correcting the negatives and reinforcing the positives, and fulfilling the Bauhaus ideals of singular design. The Seagram building was by any standard, miles ahead of its competitors. Yet it achieved this without claiming to be the future, or resenting the past. With classic interiors, a classy dark outside skin of externally mounted bronze, and topaz tinted glass; it not only looked the part, but also integrated frontier technology, to aid in wind buffering and reduce UV glare/heat. Its latticed modular steel framework also represented the way forward, not only with its curtain walling efficiency that allowed simple mountings for the traditional venetian blinds, but also with regards a lighter, stronger, more adaptable construction method that retained so called classic features. However, the buildings piece de rà ©sistance is what many of todays skyscrapers have to thank. Before Mies got his hands on the commission, he looked at the competitors, the other structural locale, and also back at his previous concepts. He then did what no one else had done. He set the tower a reasonable distance back from the street and created what we see throughout todays cities, urban landscaping. By creating this public space, this void filler that bridged the public and private sector he thereby integrated the Seagram immediately with its environment, it was this sort of thinking, that put Mies one step ahead, enabling him to cater perfectly for both ends of the spectrum by simply thinking outside of the box, where no others considered or dared to. It paid dividends, whilst also setting the trend of vertical design for decades to come. Conclusion Balance is what enables many things in life to perform at their respective bests, from the balance of work and social, to the balance of a relationship, and none more so than the design world. When it comes to the argument of traditional vs. Modern, the initial stages of design should always respect their roots, thus keeping to hand drawn methods, crafts, and human investigation like sketching and model making. It is all too easy to rely solely upon CAD and other such programs that have made some of todays design rather inert and cold, without human charm, and the only possible preservative of these features is the maintaining of traditional methods and heritage to keep the human signature alive. The investigation I carried out made this all too apparent, that relying upon technology to carry a design from inception to creation is a vitally flawed theory, and that without sacrifice of man hours and effort with my own skills, my envelope would be nowhere near as thorough or well desig ned, not saying that it is a perfect example, but what designer is without his or hers mistakes? Far too many things in life have slipped into the vast abyss that is history and all because weve become too eager and thirsty for this new age of production ease, of technological employment, whereby objects are no longer designed, they are manufactured, devoid of all the initial ingenuity. The radically simplified forms, the rationality and functionality, and the idea that mass-production was reconcilable with the individual artistic spirit. (MinusFive 2006) Within the last century, the Bauhaus is the only thing that has come in the way of the seemingly unstoppable machine age. It questioned craftsmanship vs. Mass production, usefulness vs. Beauty, and mainly whether a singular proper combined form could exist. In many areas it succeeded, especially in furniture design, with the likes of Breuer and Stam, whom renovated modern furniture with the cost effective use of steel, providing form and the most necessary function. At the end of the day, the dispute over the necessitation of design evolution will rage for years to come, the important factor which I cannot emphasise enough is the compromise, the balance, the equilibrium, and however many other words there are to describe the simple fact that both are equally as important as the other. One of the main objectives of the Bauhaus was to unify art, craft, and technology. The machine was considered a positive element, and therefore industrial and product design were important components (MinusFive 2006)

Essay --

Late 2010, early 2011, a series of demonstrations and protests began to rise in the Arab world. These protests have become known as the "Arab Spring†, or, as someone else called it, the â€Å"Arab awakening†. Those Arab uprisings had removed many authoritarian leaders from their positions; on the other hand, some governments faced this problem using repression and some fake promises toward their people. The Arab world was living a difficult economic and social situation as in Europe in 1848. Poverty, rising food prices, inflation, human rights violation, and high unemployment were the main phenomena the Arabs were facing. In addition there was much corruption of Arab leaders as shown by some of the WikiLeaks diplomatic cables. The main reasons of the Arab revolts are not limited to internal causes, so it is important to analyze the international causes such as the failure of the war on terror, the Iraqi war and the U.S.A - European strategy of the imported democracy. The protests witnessed in some of the Arab countries are somehow an expression of dissatisfaction with the economic situation. This also creates a political tension resulting from the absence of people say in power. The Tunisian revolution that took place in the self-immolation of Mohamad Bouazizi on 18 December 2010 in protest of police corruption and ill treatment, has shaken authoritarian leaders across the Arab world in areas such as Egypt, Libya, Yemen, and Bahrain. The article, which appeared under the title "A prayer for the health of the rais," began by stating that "of all the world's statesmen, the one closest to Prime Minister Benjamin Netanyahu is Egyptian President Hosni Mubarak". Thanks to Mubarak, Egypt became a strategic ally of Israel, as well as Israel'... ...opean origins. The important fact is that the way Islamism, communism and secularism have experienced many various signification with its national, regional and religious context. Applying this to secularism, Jakobsen and Pellegrini Fenella cannel have suggested to talk about secular traditions rather than secularism, secularization, or â€Å"the secular† in india, turkey, france, and many other countries with more or less homogenous histories of secularizations and debates about secularism. If we apply this approach to the Arab Region, it might be possible to identify some interconnected secular traditions in the Levant, the gulf, and North Africa. Reactions on the need for a secular state firstly appeared in the late ottoman period, or in the arab cultural movement known as the Nahda. In the early 20th century, many ideological currents influenced Arab intelligentsias.

Gvt Task 2

Running Head: GVT Task 2 GVT Task 2 Maureen O’Connor Western Governors University The mouth, pharynx, esophagus, stomach, small intestine consisting of the duodenum, jejunum, ileum, and large intestine consisting of the transverse colon, descending colon, ascending colon, cecum, sigmoid colon, rectum, vermiform appendix and anus are all part of the alimentary canal. The function of the alimentary canal is to provide nourishment. The teeth, tongue, gallbladder, salivary glands, liver and pancreas are considered to be accessory digestive organs.These organs produce saliva (salivary glands), bile (gallbladder and liver) and digestive enzymes which contribute to the breakdown process of food. Mechanical digestion begins with the process of taking food into the mouth or ingestion and chewing it until it can be moved through the alimentary canal during the propulsion process. This process includes swallowing and in a series of muscle contractions and relaxation it is then moved from one organ to another.Swallowing is performed in the pharynx while peristalsis occurs in the esophagus, stomach, small and large intestine. Breakdown of the food in the stomach, also called churning and in the small intestine are also part of the mechanical digestion process. When food leaves the stomach the process of chemical digestion begins. This is when carbohydrates, proteins, and lipids are broken down into simple sugars, amino acids, fatty acids and glycerol, otherwise known as chemical building blocks.Enzymes are chiefly responsible for carrying out chemical digestion and are secreted in the central cavity of the alimentary canal. Digestive enzymes include salivary and pancreatic amylase, present in the mouth and small intestine, maltase and lactase which are also present in the small intestine and are involved with carbohydrate digestion. Pepsin which is present in the stomach and chymotrypsin present in the small intestine both involved with protein digestion. Aminopeptid ase breaks down amino acids during protein digestion.Finally pancreatic lipase is involved with fat digestion. Summary of Two Experiments An experiment performed in the Department of Food Sciences and Nutritional Health at Kyoto Prefectual University involved polylysine which had been used as a food additive in Japan for many years. The researchers were interested in how polylysine inhibited pancreatic lipase. They performed the experiment on rats and then measured the effect of the polylysine after the rats were fed a meal.These measurements were taken after the rats had been administered fat emulsion with the polylysine and fat emulsion without polylysine. The results suggested that polylysine had the ability to inihibit pancreatic lipase in the small intestine and suppressed dietary fat absorption. A second experiment involved alpha-amylase inhibition from the white kidney bean and its effect on weight loss and blood glucose levels. Clinical studies in which subjects were given t he white bean product and their after meal glucose levels were studied.A group of subjects with diabetes were also given the white bean product and there was found to be a decrease in their after meal glucose levels. There were more clinical studies in which subjects were given varying doses of the white bean product along with amino acids with varying levels of dietary intake. The conclusion was that alpha-amylase inhibitor does have an effect on the absorption rate of carbohydrates and be a factor in weight management as well as type 2 diabetes mellitus control. Independent ExperimentQuestion|Independent Variable|Dependent Variable|Controlled Variable| What is the effect of digestive enzymes on peanut butter? |Kind of digestive enzyme added to peanut butter. |Change in consistency or texture of peanut butter after 1 hour. |Equal amount of peanut butter in each cup. | If I add pepsin and hydrochloric acid to peanut butter, this should cause a change in the consistency of the peanut butter after 1 hour. If I add lipase and hydrochloric acid to peanut butter this should cause a change in the consistency of the peanut butter after 1 hour.The lining of the stomach secretes gastric juices including hydrochloric acid which dissolves food, pepsin which is a protein-splitting enzyme and lipase, a fat-dissolving enzyme. By adding the Biuret solution to identify the presence of protein to each cup containing peanut butter, enzymes and hydrochloric acid there should be a change in color to pink or purple.

The absorption of protein then occurs and amino acids enter capillary blood via villi and subsequently transported via the hepatic portal vein to the liver.Although lipase is present in the stomach it is not very effective because the stomach is a strongly acid environment. The majority of fat digestion happens in the small intestine although it needs bile from the liver to break it down into glycerol and fatty acids. Once that occurs the fatty acids enter the lacteals of the villi for transportation via lymphatic transportation to the thoracic duct. Glycerol and fatty acids (small-chain) are transported via the hepatic portal vein to the liver.
