The Use of Agent Orange in the Vietnam War Essay -- Vietnam War Essays

The Use of Agent Orange in the Vietnam War Agent Orange is a plant killer, which was used during the Vietnam War to destroy the massive amount of trees (Nguyen, 1). The destruction that occurred, however, is far more extensive than once believed. Complications in health occur much more frequently to those exposed to the chemical than those who managed to avoid contact (Nguyen, 2). The use of Agent Orange in the Vietnam War affected the American soldier’s health and genetics. Agent Orange is a 50:50 mixture of two major compounds, 2,4-dichlorophenoxy acetic acid and 2,4,5-trichlorophenoxy acetic acid (Nguyen, 2). This defoliant also contains dioxin, which is one of the most lethal compounds known to man (Nguyen, 2). Ironically, the dioxin, which makes Agent Orange lethal to humans, isn’t intended to kill plants at all (Vancil, 1). It is extremely hard to prove, however, that dioxin is responsible for the countless illnesses acquired by many Vietnam veterans because each individual has their own tolerance to dioxin (Vancil, 1). Many soldiers in the Vietnam War encountered Agent Orange repeatedly. Their lives revolved around the 55-gallon drums, which once were filled with an extremely harmful herbicide. Unaware of the possible consequences, many soldiers built showers and hibachis out of these discarded drums (Doyle, 139). They also used the barren drums to store potatoes and watermelons (Doyle, 139). One man described to his wife how they would bathe and s...

Plant layout Essay

PLANT LAYOUT Outline of Contents: What is Plant layout? Necessity of good layout Factors affecting good layout Principles of good layout Advantages of good layout Symptoms of poor layout Types of layout What is PLANT LAYOUT? Plant layout refers to the arrangement of physical facilities such as machines, equipment, tools, furniture etc. in such a manner so as to have quickest flow of material at the lowest cost and with the least amount of handling in processing the product from the receipt of raw material to the delivery of the final product. Plant Layout is a plan of an optimum arrangement of facilities including personnel, operating equipment, storage space, material handling equipments and all other supporting services along with the design of best structure to contain all these facilities. A good layout is one which allows material rapidly and directly for processing. This reduces transport handling, clerical and other costs down per unit. Space requirement are minimized and it reduces idle machine time and idle time of man. Necessity of good plant layout Minimization of material handling Optimum utilization of available floor space Elimination of bottlenecks through balancing of all capacities Minimization o production delays Easy supervision and better manpower resources through elimination of idle time Elimination of physical efforts required by workers Elimination or improvement of objectionable operations. E.g. Operations with bad odor, vibrating operations etc. Avoiding industrial accidents Better working conditions like light, ventilation, noise control etc. Optimum utilization of machinery and equipment through proper use. Minimization of cost so that product will be available at cheaper rate to customer and  delivery in time.

Reduce material handling costs Utilize labor efficiently Reduce accidents Provide for volume and product flexibility Provide ease of supervision and control Provide for employee safety and health Allow easy maintenance of machines and plant. Improve productivity Symptoms of Poor Layout Delays and work stoppage in manufacturing process Slow movement of material through the plant Congestion of materials, components and work in progress Poor utilization of space High material handling and transportation costs Excessive handling by skilled workers Production cycles and delays in delivery Mental or physical strain on operators Difficulties in maintain effective supervision and control Underutilization of machines and workers Lack of flexibility and difficulty in production planning and control Types Of Layout: There are mainly four types of plant layout: (a) Product or line layout (b) Process or functional layout (c) Fixed position or location layout (d) Combined or group layout Product or line layout: In this type of layout the machines and equipments are arranged in one line depending upon the sequence of operations required for the product. It is also called as line layout. The material moves to another machine sequentially without any backtracking or deviation i.e. the output of one machine becomes input of the next machine. It requires a very little material handling. It is used for mass production of standardized products. Advantages of Product layout: Low cost of material handling, due to straight and short route and absence of backtracking Smooth and continuous operations Continuous flow of work Lesser inventory and work in progress Optimum use of floor space Simple and effective inspection of work and simplified production control Lower manufacturing cost per unit Disadvantages of Product layout: Higher initial capital investment in special purpose machine (SPM) High overhead charges Breakdown of one machine will disturb the production process. Lesser flexibility of physical resources. Process layout: In this type of layout the machines of a similar type are arranged together at one place. This type of layout is used for batch production. It is preferred when the product is not standardized and the quantity produced is very small. Advantages of Process layout Lower initial capital investment is required. There is high degree of machine utilization, as a machine is not blocked for a single product The overhead costs are relatively low Breakdown of one machine does not disturb the production process. Supervision can be more effective and specialized. Greater flexibility of resources. Disadvantages of Process layout: Material handling costs are high due to backtracking More skilled labour is required resulting in higher cost. Work in progress inventory is high needing greater storage space More frequent inspection is needed which results in costly supervision Combined layout: A combination of process & product layout is known as combined layout. Manufacturing concerns where several products are produced in repeated numbers with no likelihood of continuous production, combined layout is followed Fixed position or location layout: Fixed position layout involves the movement of manpower and machines to the product which remains stationary. The movement of men and machines is advisable as the cost of moving them would be lesser. This type of layout is preferred where the size of the job is bulky and heavy. Example of such type of layout is locomotives, ships, boilers, generators, wagon building, aircraft manufacturing, etc. Advantages of Fixed position layout: The investment on layout is very small.  The layout is flexible as change in job design and operation sequence can be easily incorporated. Adjustments can be made to meet shortage of materials or absence of workers by changing the sequence of operations. Disadvantages of Fixed position layout: As the production period being very long so the capital investment is very high. Very large space is required for storage of material and equipment near the product. As several operations are often carried out simultaneously so there is possibility of confusion and conflicts among different workgroups.

Discuss how ICT has changed modern society Essay

Our modern day world becomes more and more modern every day, with new technologies and advances coming up. ICT impacts all parts of our lives, and has had a massive impact to society, the environment and its future. Information and Communication technology opened up a whole new industry in the work sector, and that is clearly one of its many advantages. The ICT industry in Australia alone employs over 541,000 professionals. Meaning over half a million people with actual degrees in ICT related subjects. At least 500,000-1,000,000 are expected as amateurs who have worked in the industry before. Our reliance on computers and technology is the reason that this number continues to increase. Although employment rates in ICT have stabilised from the roaring it had over the past decade, it is still employing thousands of people annually. Increased employments rates in this sector allows a fast form of global communication and trade. ICT also left a mark on the way in which society communicates. E-mails, instant messaging, video conferences are all new ways in which people communicate effectively every day. These in turn, impact the economy. People have a much better standard of living as they don’t have to pay for phone bills, plane tickets, or spend money on gas to visit their friends. Instead, this can all be done within a few seconds with a computer costing less than a single plane ticket. Many schools worldwide use the internet for interactive trips for their students. With the economy suffering in the USA, may schools have adopted using video websites such as YouTube to keep the students interested with the issues of the world. It is only human to get a rush as soon as you sit down in front of a computer, same for kids. Students studying Applied ICT at AS and A2 level are learning topics that were taught at degree levels only a decade ago. So ICT skills needed for the workforce are actually taught earlier on in life now. That’s how vitally important they are. Nothing can be ‘complete’ without mentioning global warming. ICT has reduced CO2 emissions from paper refineries worldwide, which in turn reduces the amount of global warming. Also, if you were to write on paper, you would need plenty of light and paper to do so, instead, ICT gives you the light of the screen, and pixel paper. This can also lead to a decrease in global warming statistics that have been rising ever since it was proven. No matter how flat you make a pancake, it will still have two sides. So does the argument about the impact of ICT. Every upside comes with an equal downside, for example, even though ICT courses are offered to much younger ages now, that still doesn’t disregard the fact that specialist equipment and rooms are needed for these courses. Specialists for troubleshooting must be on call, and security can be one of the major issues, as people know they’re constantly being watched, and this may effect their strive to learn. For example if someone knows they’re being watched, they wont be so eager to learn anymore. Security issues and the feeling of always being watched and monitored can consequentially cause panic attacks, and increase stress. Stress is the number one leading factor for heart attacks worldwide. ICT is a package that comes with health risks. Some include; extremely low frequency radiation ( caused by the lack of sun and being exposed to electricity for too long), Eyestrain (caused by poor lighting and a flickering screen, causes headaches, weak vision and pain), and Repetitive Strain Injury ( caused by repetition of the same movement , causes aching in arms and shoulders, loss of strength). The wrong posture while using the computer is a theory for the increase in rates of Scoliosis. As jobs are being created by ICT, jobs are also lost as many office clerks and people are being replaced by machinery. Delicate and secure information can be easily duplicated without a trace. This raises the whole security of ICT issue IT crime, hacking, fraud, and tacking were one of the most important issues of our time at the stat of the millennium. In 2004, the  leading cause of credit card fraud was from the internet, and unsecure websites that sold merchandise such as books, electronics, and even furniture.

How Television Affects The Family essays

How Television Affects The Family essays Opinion Essay: How Television Affects The Family The year was 1923, and Philo Farnsworth had an invention, and he called it The Television.(Farnsworth Cronicles) He had no idea how it would change the world. Since its arrival it has had a lasting impact on family life, throughout the world. When it first arrived, you couldnt find a family without one. Everyone was glued to their T.V. sets. Little has changed since its invention 81 years ago. Televisions became more modern and people couldnt pry themselves away from the tube. Soon enough this was affecting just how a family acted with each other. Parents were seeing less and less of their children and children were becoming couch-potatoes. The television has changed the way families were and are. When television was invented, it was not intended to be a replacement. Family is the most important influence in a child's life, but television is not far behind. When parents began to use the television as a baby-sitter or a teacher for their children is when they began to lose touch with their children. As the children grew up watching television and not interacting with their parents, they grew less and less apart. Children in the United States watch about 4 hours of TV every day. Watching movies on tape and playing video games only adds to time spent in front of the TV screen. It may be tempting to use television, movies, and video games to keep your child busy, but your child needs to spend as much time growing and learning as possible. Playing, reading, and spending time with friends and family are much healthier than sitting in front of a TV screen. (AAP) This is the truth. How can your child develop or how will you help them develop if you let them live their young life in front of a television? In the film, the Cable Guy, the mother of Jim Carreys character in the mo ...

Spectroscopy Definition and Difference vs Spectrometry

Spectroscopy Definition and Difference vs Spectrometry Spectroscopy is the analysis of the interaction between matter and any portion of the electromagnetic spectrum. Traditionally, spectroscopy involved the visible spectrum of light, but X-ray, gamma, and UV spectroscopy also are valuable analytical techniques. Spectroscopy can involve any interaction between light and matter, including absorption, emission, scattering, etc. Data obtained from spectroscopy is usually presented as a spectrum (plural: spectra) that is a plot of the factor being measured as a function of either frequency or wavelength. Emission spectra and absorption spectra are common examples. How Spectroscopy Works When a beam of electromagnetic radiation passes through a sample, the photons interact with the sample. They may be absorbed, reflected, refracted, etc. Absorbed radiation affects the electrons and chemical bonds in a sample. In some cases, the absorbed radiation leads to the emission of lower-energy photons. Spectroscopy looks at how the incident radiation affects the sample. Emitted and absorbed spectra can be used to gain information about the material. Because the interaction depends on the wavelength of radiation, there are many different types of spectroscopy. Spectroscopy Versus Spectrometry In practice, the terms spectroscopy and spectrometry are used interchangeably (except for mass spectrometry), but the two words dont mean exactly the same thing. Spectroscopy comes from the Latin word specere, meaning to look at, and the Greek word skopia, meaning to see. The ending of spectrometry comes from the Greek word metria, meaning to measure. Spectroscopy studies the electromagnetic radiation produced by a system or the interaction between the system and light, usually in a nondestructive manner. Spectrometry is the measurement of electromagnetic radiation to obtain information about a system. In other words, spectrometry can be considered a method of studying spectra. Examples of spectrometry include mass spectrometry, Rutherford scattering spectrometry, ion mobility spectrometry, and neutron triple-axis spectrometry. The spectra produced by spectrometry arent necessarily intensity versus frequency or wavelength. For example, a mass spectrometry spectrum plots intensity versus particle mass. Another common term is spectrography, which refers to methods of experimental spectroscopy. Both spectroscopy and spectrography refer to radiation intensity versus wavelength or frequency. Devices used to take spectral measurements include spectrometers, spectrophotometers, spectral analyzers, and spectrographs. Uses Spectroscopy can be used to identify the nature of compounds in a sample. It is used to monitor the progress of chemical processes and to assess the purity of products. It can also be used to measure the effect of electromagnetic radiation on a sample. In some cases, this can be used to determine the intensity or duration of exposure to the radiation source. Classifications There are multiple ways to classify types of spectroscopy. The techniques may be grouped according to the type of radiative energy (e.g., electromagnetic radiation, acoustic pressure waves, particles such as electrons), the type of material being studied (e.g., atoms, crystals, molecules, atomic nuclei), the interaction between the material and the energy (e.g., emission, absorption, elastic scattering), or specific applications (e.g., Fourier transform spectroscopy, circular dichroism spectroscopy).

Article Review for Graduate Level Educational Research Class Essay

Article Review for Graduate Level Educational Research Class - Essay Example Maslow’s understanding is that ‘if one is to transform the performance of an average person in any field , then one has to study the peak performers, understand the way they work and think and then impart the same skills to the performer who is average to reach the peak’. This understanding was a driving force for Smith and Strahan who chose to study three experts in the field of teaching, watch them in an active environment and collect the information which can help them to create a set of personality traits that makes expert teachers. The study, although was very minute, extensive and thorough, seems to be little rigid. There are many ways and aspects of the study where the researchers could have taken a broader path. This study was undertaken to create a model which can be a tool for beginners in teaching field to understand what makes an expert teacher and how to become one. The aim of the study was to make American Public schools a centre of excellence by helping the teachers of average quality to learn from the experts. Now, when we talk of development of whole country where thousands of schools are involved, is it really valid to create a prototype based on the study of just three teachers? I think that the study should have been conducted nationwide and not just in one state. Teachers with different backgrounds, different cultures and different states should have been studied as we all know that everything changes with difference in the state. This not only would have helped to gain more insight into understanding the expertise in teaching but also would have generated more and more central skills as

Analysis of Marketing Mix Research Paper Example | Topics and Well Written Essays - 2000 words

Analysis of Marketing Mix - Research Paper Example This includes increasing the number of products in the market while maintaining quality and low production costs. Product development ranges from identifying customer need to designing activities that analyze and refine new ideas. These ideas bring about new products or refine existing products. Unique, high quality and affordable products give a business an advantage over competitors (Brassington and Pettitt, 2005). Beauty for price Hairdressing has faced steep competition from similar businesses in the region. Product development requires intense marketing, especially in a competitive industry. Investing in marketing involves advertising, employing human marketers, promotions, and other activities that sell out the business. With the upcoming events, the salon needs intense marketing and reorganizing the business process. This includes buying better hairdressing equipment and employing more hairdressers. Human resource is necessary for service delivery. Events such as sports and co nferences have several participants and more workers are required to handle the large numbers effectively. Employing experts improves the quality of services offered which surpass competing businesses. Introduction of new business services such as massage, manicure, pedicure, and other related services can also increase the number of customers (Adcock, Halborg and Ross, 2001). Businesses distribute their products in different ways to provide customer convenience. Distribution methods depend on the type of business and its intended customers. Global companies have distribution centers in several regions around the globe. Products are dispatched from the distribution center nearest to the customer (Jobber, 2010). This reduces distribution cost and time required for the product to reach the customer. Retailers incorporate several distribution methods that focus on customer satisfaction at a minimum cost. Efficient and pleasurable shopping experiences that meet customer needs and market demands are required by business organizations. Most customers prefer businesses providing quality and convenient services. A salon can introduce mobile services to its customers. During major events, most participants reside in hotels and prefer room services. Starting mobile room services would serve as a boost to business activities (Jones Mothersbaugh and Beatty, 2003). E-commerce and advertising through the internet is another way of ensuring the availability of products. Customers can access the business website to learn about their services and book appointments. The distribution channel in a hairdressing business consists of wholesalers who sell and supply products to the salon. The salon then uses the products to offer services to customers. Maintaining a constant link with suppliers is necessary for constant availability of products for customer convenience. The business location also determines customer convenience. Customers prefer business locations that are easily acc essible.  Ã‚
