Sustainable Agriculture Essay -- Research Paper Ranching Farming Paper

Sustainable agribusinessAgriculture has been a fundamental component of human societies for centuries. It is so fundamental in fact that it is often forgotten by those dependent on its products, but not directly involved in the production. As we enter the 21st century, agriculture is beginning to receive more caution from the general public as the implications of farming are realized and the problem of potential world wide food shortage is addressed. With the future in focus, a great deal of agricultural establishment uses words like biotech, and high-tech to describe their goals for U.S. agriculture. With few exceptions, traditional agriculturalists see a continuing trend of industrial agricultural practices that deal to drive production to fewer, larger, and more specialized production units which are virtually responsible for all stages of the production globally. This increased specialization is dependent on unsanded biological technologies and information technologies at all levels from farms on which the food is produced to the markets where it is distributed. While these forecasts are legitimate, a growing number of agriculturalists, concerned public, and educators envision a real different future for agriculture. Such a view is represented in the writings of John E. Ikerd, an agricultural economist and Professor Emeritus at the University of Missouri. In his paper, Sustainable Agriculture a necessary alternative to industrial agriculture, Ikerd questions whether the guiding trends of agriculture in the past hundred years can go forward to be the guiding force of agriculture. He argues the while the tools of the high-tech future may be different from the tools of the industrial age, the objectives to specialize, mechan... ...l.--- Sustainable Agriculture A autocratic Alternative to Industrial Agriculture 7 December, 1996.

sterilization Essays -- essays research papers fc

The only way to ensure that sterilization has occurred is to use the biological monitoring methods. This is because these are the only tests make which show whether or not actual microbial life has been killed. Biological methods are the only ones which are recommended by the CDC (Centers for Disease Control and Prevention), the AAMI (Association for the Advancement of health check Instrumentation), the AMA (American Medical Association), OSHA, and OSAP (Office Safety and Asepsis Procedures Foundation)Biological monitoring is basically evaluating a sterilization process by rendering highly resistant bacterial spores biologically inert. The highly resistant bacterial spores used varies depending on what kind of sterilizer was used. For example Bacillus stearothermophilus spores for steam and chemical vapor sterilizers, Bacillus subtilis spores for dry set off and ethylene oxide sterilizers. These specific Bacillus spores are used because they are more resistant, and present in gr eater numbers than are the common microbial contaminants ready on patient care equipment. If it is proven that these spores have been killed, it is strongly implied that other potential pathogens in the load have also been killed. In this method, living spores which are resistant to whichever sterilizing agent is being tested are prepared in either a self contained system, such as dry sp...

All of these people are not remembered for their birth or death dates, still rather what they did with their dash. The dash that goes between their birth and death dates on their headstones. The dash that says what a person has accomplished in their life. The dash that takes up so modest space, but holds so much meaning. What will you do with your dash? Will your dash be one of accomplishment, of success, of compassion, of love, of happiness? I inclination you more than luxuriant of all of these things to make up your dash.

Creon As The Tragic Hero Of Antigone by Sophocles Essay -- Greek Sopho

Creon As The Tragic Hero Of Antigone by SophoclesGreek calamity would not be complete with out a sadal hero. Sophocles wrote Antigone with a specific character in mind for this part. Based on Aristotles definition, Creon is the tragic hero of Antigone.Creon fits Aristotles tragic hero traits as a significant person who is faced with difficult decisions. Creon is significant because he is king. This makes him both renowned and prosperous. Creon is not completely good nor completely bad he is somewhere in-between, as humans are. The audience can relate to this and they admire his qualities of intelligence in policy-making affairs. They can also relate to his ability to make hard decisions with apparent ease. These hard decisions are what lead Creon to fit Aristotles definition of a tragic hero. Creon faces decisions that lead to a no-win situation, with confidence, and he makes the best decision he can, based on his beliefs. He believes that Polyneices should not be buried because he was a traitor to his family. This decision affected Antigone greatly, and Creon knew that the decision would be hard on some people. Family and burials are very important in society, and Creon is asking Antigone to not require them, to only consider that Polyneices was a traitor to his home city. Creon is then faced with the knowledge that Antigone went against his will and law, and buried her brother. Again, Creon is faced with a hard decision. He mustiness choose to kill his own family memb...

Feasibility of Nationalising the South African Mining Sector Essay

IntroductionThe mining industry forms the foundation of southwesterly Africas economy. presently south Africa is the biggest producer of platinum in the world and one of the top producers of gold. Julius Malema, the leader of the African National Congress Youth League (ANCYL) was at the brain of having a detailed perspective on the nationalisation of mines in siemens Africa at the beginning of 2010. Malema believes the nationalisation of mines willing solve all economic disparities in South Africa. There are many South Africans who agree or disagree with this idea. The following discussion will provide answers to why it should be through and who bring ins or why it should non be done and what the shortcomings are and the be that the country will incur if it were to be done as well as examples of nationalisation in other countries (Roberts, 2011).DiscussionNationalisation is the operation of transferring ownership from the private sector to the public sector. According to t he minister of finance, Mr Pravin Gordhan stated on the troop 14, 2011 that nationalisation of South Africas mines and other economic assets are not politics policy. Nationalisation of mines means the democratic governments ownership and statement of Mining activities, including exploration, extr do, production, processing, trading and beneficiation of mineral Resources in South Africa(ANCYL, 2010). Therefore this would mean that no mines would be publicly possess however they would be owned by the state. It has been sixteen years since apartheid and the white minority of 10% of the population owns 80% of the countrys economic wealth.The Freedom Charter is a memorandum that expresses the economic, social and political will of South Africans and according to the document, the mineral wealth of South Africa beprospicients to the mountain as a nation. It is against this rumpground upon which a concrete typeset on the nationalisation of Mines is formulated in order to guide the ANC in the transfer of mineral wealth beneath the soil to the ownership and benefit of the people as a whole (ANCYL, 2010). If the state owns the mines it would allow them to manage the economy by controlling the important industries. They could also invest a big bill of money and make their services more efficient.Nationalisation of the mines does not mean all sectors are in the hands of the countrys citizens and that they will benefit from all the sectors. It does not yet say anywhere what the ratio (between state owned and privately owned) of the division will be when nationalisations befalls, if it does. Therefore people shouldnt think that the state will automatically have over half or a larger percentage. An important factor is whether nationalisation will be with or without compensation. It would almost be unsurmountable to nationalise with compensation as the government currently doesnt have the figure of about R 2-trillion which is how often it would cost to purchase the mines. But on the other hand, expropriation without compensation would cause a collapse of the Johannesburg Stock Exchange (JSE). This would bring down provident and pension off funds at the analogous time. A large number of servants and citizens would be without their retirement investments as well (ANCYL, 2010). Therefore this poses a big problem already. or so people might think why the mines should be nationalised. Below are three reasons.1. Nationalisation to increase the States fiscal capacity and remedy the working conditions (ANCYL, 2010). It states that the money received from taxes is not enough to help each and every single South African citizen, which it is not. Education, healthcare, safety and security and housing will not be provided to the masses if the government is not in control of the important sectors. There have been other success stories, such as in Botswana where nationalising the mines provided mineworkers with a safer working environment and higher w ages. 2. Nationalise to Industrialise and Create more jobs (ANCYL, 2010). More jobs will be created and industrial investors will be attracted to take to education, expertise and the economy. 3. Nationalisation to transform South Africas unequal spatial development patterns (ANCYL, 2010). This means the areas that will be focused on will be ones which will be sustainable in the future as well as effective. Smaller areas that have never been mined before could be targeted as it will provide more jobs in these areas which rarely see economic activity (ANCYL, 2010).Malema believes that everybody in South Africa has the right to the wealth that is produced and that the state should own the larger part of the mines. South Africa is divided as we speak. Weve got two economies in one country, two nations in one country, and it is nationalisation that will unite us (Andrew, 2011). He also believes many jobs will be created once the mines are nationalised. Patrice Motsepe, a South African business enterpriseman, states that he would back Malemas decision as long as it is in the best interests of South Africa. The ANCYL believes South Africas minerals, water, land and marine resources should be used to maximise growth of South Africas economy and not purely for profit (Shivambu, 2010).If the mines are nationalised, new economic centres will be actual, new industrial development zones will be established, jobs will be created as the mines owned and controlled by the state will increase local beneficiation and industrialisation of the available mineral resources, and local economies will be developed (Shivambu, 2010). General Secretary of Congress of South African Trade Union (COSATU), Zwelinzima Vavi says that Nationalisation can bolster our economy and it will always ensure development (Beukes, 2011). He said that the nationalisation of the mines will make available money to all the people of the country, not only those who are currently working in the private secto r (current mine owners) (Beukes, 2011). One of the ANCYLs argument is that nationalisation was a demand found in the Freedom Charter and that South African citizens should share the mineral wealth of the nation between each and every one (Achary, 2010).Thus there are valid reasons for the mines to be nationalised but the study concern is the cost that the country would incur to make nationalisation happen.Nationalisation is an unaffordable, untimely and frankly unnecessary suggestion, which has already undermined market stability (Time, 2009). It would cost South Africa R1.4 to R2 trillion to nationalise the mines which seems silly if you think South Africa has the fifth biggest mining industry in the world. This figure does not include extra running costs as well as the costs that go with running loss-running mines. This shows it is a big part of the economy and would be tough to be nationalised. This figure is the same as trebling South Africas national debt over a single night, which is unrealistic (Time, 2009). The debate on the thorny issue heated up with business executives and analysts warning that nationalisation would damage the economy (Isa, 2011). Many say it is a disaster and has been for every country who has tried to pull it off. Susan Shabangu said consideration of the ill-use was misguided, as the real issue was to address poverty, unemployment, and inequality (Isa, 2011).This shows that the debates that are ongoing will deter foreign investments. The ANC do realise that its close to impossible to nationalise the mines and come off on the right foot but are currently looking at models of how it could be implemented effectively (Isa, 2011). The nationalisation of mines has also been seen as a ploy to try and save Black Economic Empowerment (which has been in place in South Africa for a while, but has not achieved what it hoped to) and not focusing on the amount of poor in the country as well as the amount of unemployed workers (Business Day, 2 011). The market honor of South African mines (listed) is almost 850 billion rand which is above a third of the countrys total Gross Domestic Product (GDP). Therefore the government should be more concerned over matters such as the education level and the health of the countries people.Zambia nationalised the copper mines, which supplied 90% of its exports, in the early 1970s. It ended up hiring back the multinational copper companies to manage them (News24, 2010). Zambia is the worlds 11th largest producer of copper. The mines were nationalised in 1969 and at this time were exporting about 700 000 tonnes of copper per annum. By the year 2000, exporting figures had constantly decreased to 225 000 tonnes. The result of the decline was partly because of a lack of investments as well as mismanagement of the mines. Zambia has neither the superior nor the skills to run the mines by itself (Time, 1969). Other factors were the drop in the expense of copper, a lack of skills among the ci tizens in Zambia and they were unable to raise capital. They lacked a strong plan with which to back up their initial aim (Time, 1969).Restrictions were placed on exports and imports which resulted in exchange rates rising and therefore gains from exports reduced. Zambia also failed to save earnings when the copper price was high and thus when the price fell, they suffered immensely. Even though the situation is not exactly the same, it does show that to nationalise mines a lot of debate needs to occur as well as research and ostensibly the country needs the required funds to make sure it can be made possible. South Africa does not have these funds at the moment and thus would not be able to nationalise the mines unless they are willing to operate with huge debts which is unworkable (Osei-Hwedie, 2003).ConclusionNationalisation is an unaffordable, untimely and frankly unnecessary suggestion, which has already undermined market stability (George, 2009). This statement sums up the i dea of nationalisation of mines in South Africa. It obviously has its advantages such as giving higher wages and creating more jobs but it is clearly evident that the positives are outweighed by the negatives. With so many jobs in South Africas mining sector at stake, it is irresponsible to talk about placing this key sector of the economy in the hands of government people. The country does not have nearly enough funds for this project to take place and thus in my view should not take place in eve in the near future (Marais, 2010).Reference ListACHARY, N. (2010).

Since its inception, Gadhia Solar has been a techno logic tout ensembley, solution focused company driven by strong passion for environmental and social contribution combined with uplifted creativity and integrity. The company is into researching and developing new alternatives to harvest the unfathomable source of energy.Automated Steam Jacketed Vessel is a new kind of cooking vessel in itself. The vessels used for soalr thermal cooking are one with direct dig of steam and have limited usability. But with jacketed cooking vessel, any kind of pabulum item can be cooked since the food does not come in contact with the steam. For cooking food, the temperature of the vessel should be maintained in the bracket of 80-120OC which leave not only cook the food faster, but also wont burn it. The vessel was designed with the help of Dr. Vivek Wasekar and for automation of the cooking unconscious work at I worked with Mr. Veera Prasad Gadde.For the automation, a Programmable Logic Controller (PLC) is being used which get out read the temperature inwardly the vessel with the help of a Resistance Temperature Detector (RTD) and thereby control the cooking pr ocess. Two Solenoid Valves are being used to control the flow of steam and the abridgement wrong the jacket. And also a bosom regulator is being used to regulate the pressure of the steam from the header. The parabolic dishes allow for generate the steam inside the header. When the outlet of the header is opened, the steam at blue pressure at around 15 bar volition be let into the outlet.The pressure regulator testament regulate the pressure of the steam to a value of around 3 bar which result go towards first solenoid valve. When the cooking process is started, the first valve depart open and let the steam into the jacketed vessel. The steam go out raise the temperature and thereby cook the food. For the initial implementation, three food items have been considered i. e. rice, dal and vegetables. According to the food item being cooked, the controller will decide the temperature and time for cooking and proceed with the cooking.

Introduction Gadhia Solar Energy Systems Pvt Ltd. has been making Scheffler reflectors for various purposes. The raw worldly idea that leads to the development of the Scheffler- Reflectors was to make solar cooking as comfortable as possible.At the same time the device should be build in a way that allows it to be constructed in any rural welding workshop after a certain period of training. The topically uncommitted poppycocks must be sufficient for the construction of the reflector. The movement started when the first well functioning Scheffler-Reflector (size 1,1m x 1,5m) was successfully built by Mr. Wolfgang Scheffler in 1986 at a mission-station in North-Kenya. Since therefore the technology has been continuously improved and passed on to many motivated people. This lead to the use of Scheffler reflectors in not just cooking but also other applications like VAM, cold storage, etc. For cooking application, these Scheffler-reflectors are used to generate steam in the header pipe.The urine inside the header is arouseed with the reflector and due to the continuous input of heat steam at high pressure is generated inside the header. When the outlet of the header is opened, this steam at a higher temperature and pressure is used for cooking. A valve is connected to the steam line which goes to the cooking vessel. When the valve is opened, the steam is let into the vessel and hence the food is cooked with it. Gadhia Solar Energy Systems Pvt Ltd has installed many solar cooking systems in In dia. They have installed the worlds largest solar parabolic concentrated technology systems at Shri Saibaba Sansthan Trust, Shirdi. This system uses the same Scheffler- reflectors to produce steam from water and uses that generated steam to cook the food.The solar cooking vessels used currently are being operated manually and motifs at least one labor per cooking vessel to operate. The cooking is done by direct injection of steam into the vessel. When the food is cooked by direct injection of steam into the food, as the steam is at high pressure and temperature, it comes out of the vessel. Therefore all of the energy of the steam cannot be utilized for cooking. This increases the heat losings and also increases the cooking time. also due to the type of vessel, it is not possible to cook different types of food. Risk of contamination is also involved if the water source is not clean. So for this purpose a new design of cooking vessel was proposed.This vessel used the energy of stea m to heat the food without g palpebrae path in contact with it. The Steam Jacketed Cooking Vessel Page 7 was designed to solve the problems which were faced by the earlier used cooking vessel. In this vessel, the steam was being passed in the jacket around the cooking vessel. As the steam condenses inside the jacket, it transfers its heat energy to the food inside and cooks the food. For the Automation of the cooking process, a Programmable Logic Controller is used which will control the temperature inside the cooking vessel and cook the food accordingly. The temperature inside the vessel will be measured by a RTD (Resistance Temperature Detector).This reading will be processed by the PLC as an Analog Input, and according to the food item selected to be cooked, the PLC will select the cooking temperature and time and start the process on users command. The process can be controlled by a START button, impediment button, and food type selection button defining RICE, DAL and VEGETAB LE for apiece button. The operator first needs to select the type of food that has to be cooked. According to the selection, respective LED will turn on which will show the food item selected. Even after selecting an item, the choice can be changed to another food item. After selection, the START button is required to be pressed which will start the cooking.The cooking algorithm will take rush of the temperature and the time required for cooking. If the food gets cooked before the timer gets over, or something goes wrong with the process, the operator can manually shut everything down by pressing go against button. This cooking vessel will increase the types of food that can be cooked with steam. The automation of the vessel will minify the need of manual labor and will also cook the food faster at optimum temperatures. Page 8 2. Solar Thermal Cooking 2. 1 The Scheffler Reflector The Idea The basic idea that leads to the development of the Scheffler- Reflectors was to make sola r cooking as comfortable as possible.At the same time the device should be build in a way that allows it to be constructed in any rural welding workshop in southern countries after a certain period of training. The locally available materials must be sufficient. The Technology To make cooking simple and comfortable the cooking-place should not have to be moved, even better it should be inside the offer and the concentrating reflector outside in the sun. The best solution was an eccentric, flexible parabolic reflector which diffuses around an axis parallel to earth-axis, synchronous with the sun. Additionally the reflector is change to the seasons by flexing it in a simple way. How does this work? The reflector is a small lateral section of a much larger paraboloid. The inclined piece produces the typical elliptical shape of the Scheffler-Reflector.The sunlight that falls onto this section of the paraboloid is reflected sideways to the focus located at some distance of the reflec tor. The axis of daily whirling is located exactly in north-south-direction, parallel to earth axis and runs through the centre of gravity of the reflector. That way the reflector always maintains its gravitational equilibrium and the mechanistic tracking device (clockwork) doesnt need to be driven by much force to rotate it synchronous with the sun. The focus is located on the axis of gyration to prevent it from moving when the reflector rotates. The distance between focus and centre of the reflector depends on the selected parabola. During the day the concentrated light will only rotate around its own centre but not move Page 9 ideways in any direction. That way the focus stays fixed, which is very useful, as it means the cooking-pot doesnt have to be moved either. In the course of the seasons the incident angle of the solar beam of light varies + / 23. 5 in relation with the perpendicular to earth-axis. The paraboloid has to make out the same change of inclination in order to stay directed at the sun. Otherwise its not possible to capture a sharp central point. But the centre of the reflector and the position of the focus are not allowed to move. This is only possible by shaping the reflector after another parabola for each seasonal inclinationangle of the sun, i. e. for each day of the year.This means the reflector has to change its shape. The reflector-frame is build for equinox. By inclining and elastically deforming the reflectorframe all other parabolas can be achieved with sufficient accuracy. changing the inclination and deforming the reflector are mechanically combined the two pivots, at each side of the reflector-frame, and a pivot in the centre of the reflector, do not form a line, but the second is located below. That way inclining the reflector leads to a change in its depth, the centre of the reflector is lifted up (big radius of crossbars) or pressed down (small radius of crossbars) relative to the reflector-frame.Its enough to adjus t the upper and lower end of the reflector to their correct position to obtain a sufficiently exact reflector-shape. The setting is done by a telescopic bar at each end of the reflector. Adjusting the reflector-shape has to be done manually every 2-3 days. When all concentrated light enters the opening of the cooking-place installed at the focal point the correct reflectorshape is achieved. After passing the opening the light is redirected by a small reflector (secondary reflector) to the black bottom of the cooking pot. There it is absorbed and transformed into heat. The efficiency for cooking, i. e. heating water from 25C to 100C, can reach up to 57% and depends on the cleanliness of the eflector-surface and the state of insulation of the cooking-pot. At the focalpoint itself we have measured optical efficiency of up to 75% (with 2mm ordinary churl mirrors). Depending on the season an elliptical reflector of 2,8m x 3. 8m (standard size of 8m? SchefflerReflector) collects the sunl ight of a 4,3m? to 6,4m? area, measured perpendicular to the direction of the incident light (aperture). That way the cooking power varies with the season. As an average a 8m? Reflector can bring 22 liters of cold water to boiling temperature within one hour (with 700W/m? direct solar radiation). Page 10 There are many options for the design of the cooking-place.Mostly it is integrated into a kitchen building and provides the possibility to use firewood for cooking when the sun doesnt shine. Depending on the type of food which is cooked there is no need for a secondary reflector. This increases the efficiency and simplifies maintenance. Instead of a cooking-place a backing-oven, steam-generator or heat-storage can be installed at the focal-point. Page 11 2. 2 Steam Generation With the use of the Schefflor Reflectors, steam at high temperature and pressure can be generated with ease. Steam in saturated temperature can be made available at high pressure by concentrating the focus a nd heating the water in a closed(a) system with the focused heat. The focus of the reflector has to be concentrated onto a receiver of the header pipe.The receiver is painted black to absorb most of the radiation incident on it. The temperature of the focus of a 16m2 Scheffler Reflector can be as high as 700oC and at the receiver it is around 230oC. At such(prenominal) high temperatures, the water inside the header is being heated. Because of the continuous heat supply from the reflector, the water inside the header gets converted into steam. With time, more steam is being generated and pressure inside the header increases. It is possible to get pressure of 15 barg in around 4 hours using four 12. 5 m2 Scheffler Reflectors under beau ideal conditions and this steam can be used to cook two batches of 25kg of rice. Page 12 2. Current procedure of cooking The current procedure for cooking is by direct injection of steam into the cooking vessel. The food cooked by this procedure con sists of mainly rice, dal and some vegetables. All of them are cooked in direct steam. number 1 the outlet valve of the header is opened to a little extent. The drain valve at the vessel is opened to remove the condensate. After every cooking session, there is remaining condensate in the steam line. Since that condensate should not come in contact with food, it needs to be drained out first. After the condensate is removed, the condensate valve is closed and the steam is let into the cooking vessel.The cooking vessel contains a preoutlined amount of water with the food to be cooked. The steam is passed through the mixture, the temperature increases and the cooking starts. Also the operator needs to stir the mixture at regular intervals. In a 100 liters cooking vessel, it takes almost 15 minutes to cook around 28 kilograms of rice. Since the process involves direct injection of steam, the water used reaches the boiling quickly and the food gets cooked faster. But during cooking, af ter the water has reached its boiling point, a coarse amount of steam goes starts to escape the vessel as the vessel has an open lid. This results into loss of a lot of heat energy which could have been used in cooking the rice quickly.When the food gets cooked, the stand of the vessel has a tilting arrangement with the help of which the operator can take out the food from the vessel. So all the valves are closed and then the vessel is tilted to take the food out. The food is not processed after that, it is collected and served directly. Page 13 2. 4 Current Design of vessel The current design of the cooking vessel is very effective for direct steam cooking. But for the food items which cannot be cooked by steam directly, it is very difficult for the operator to cook such foods. As mentioned the current design uses a direct injection system. The steam from header is carried by the steam line to the vessel where it is regulated with the help of a ball valve.The construction of the vessel is made to facilitate cooking with the help of steam. The vessels bottom dish is a regular torispherical dish and it has a shell of same diameter of that of the bottom dish. There is another plate with a defined curvature above the bottom dish with small holes in it. This plate is for passing the steam into the cooking material. When food is put into the vessel, some predefined amount of water is added with it. So during cooking process, the water gets heated initially and then the cooking starts. Due to direct injection of steam at temperature greater than 100oC, the water reaches boiling point in a short period of time. Thus the cooking process starts.The operator closes the valve when he thinks that the food is appropriately cooked. Figure 1 Previous Direct Steam Injection Cooking Vessel Page 14 The present design has some benefits, but there is also another side to it. There are some problems with the current design which cannot be find out without changing the design. The Advantages and Disadvantages of the present design are listed below. Advantages 1. It facilitates faster cooking time. 2. Since less material is used in manufacture, it saves manufacturing cost. 3. The design is simple which reduces manufacturing time. 4. As it is lighter, it is easier to transport. Disadvantages 1. There are substantial heat losses during the cooking process. 2.Since the operators cook in an open lid vessel to keep a watch on the food, lot of steam escapes the vessel resulting decreasing the efficiency of process. 3. If the condensed water in the steam line is contaminated, then there are chances of the food getting contaminated. 4. As the outer shell is not insulated, operator has to be cautious or it could lead to injuries. Page 15 3. Steam Jacketed Cooking Vessel. 3. 1 Designing the Vessel. The design of the vessel was to be made in such a way that it is easy and economic to manufacture. The material chosen for the pilot project of Steam Jacketed Cooking Ve ssel was Stainless Steel of the grade 304. This material was chosen as it is not affected by steam and it also resists corrosion. The size of the vessel was chosen to be 100 liters.The dimensions of the inner vessel were taken from the existing direct steam injection vessel whose volume was 10 liters. Then according to the pressure calculations, the thickness of the sheet and volume of the jacket was defined. The thickness of the vessel is defined as 4mm and volume of the jacket is approximately 1 cubic m for a pressure of 3 barg inside the jacket of the vessel. The vessel is having 3 openings in the outer shell. Two of them are on the horizontal shell and one is in the bottom of the outer dish end. Out of the three openings, one is used for steam injection, one for a safety valve and the bottom one for removal of condensate.All the openings are of 1 inch diameter and will have pipes welded to it for injection of steam, safety valve and condensate removal. The vessel will have two more openings which will be used to mount the RTD and the temperature gauge to measure the temperature inside the vessel. The final drawing of the vessel is shown in FIG 1. Figure 2 Steam Jacketed Cooking Vessel. Page 16 4. Steam Flow Diagrams. Water is supplied to the header army tank from an overhead tank. Either the overhead tank is at a greater height than that of header, or a sometimes a small pump is used to pump water into the Header. The Solar Concentrators are focused on the receivers mount on the header pipe.The receivers are painted black to absorb maximum amount of radiation incident on it. These receivers heat the water inside the header and generate steam at higher pressure. This generated steam is vented to the Steam line and the pressure is controlled by the Pressure ordinance valve. The solenoid valve SOV1 controls the steam input into the vessel. Thus the temperature inside the vessel can be controlled by controlling SOV1. As the steam is let inside, it will con dense after giving its heat. For removal of this condensate, another solenoid valve has been provided SOV2. This valve will remove the condensate at regular intervals. Figure 3 Steam Flow Diagram Page 17 5.Automation 5. 1 Instruments required. 1. Programmable Logic Controller A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistor to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or nonvolatile memory.A PLC is an example of a real time system since output results must be produced in response to input conditions within a limited time, other wise unintended operation will result. 2. 2-way ON/OFF Solenoid Valve A solenoid valve is an electromechanical valve for use with liquid or gas. The valve is controlled by an electric current through a solenoid in the case of a two-port valve the flow is switched on or off in the case of a three-port valve, the outflow is switched between the two outlet ports. For this application, two valves will be used. One will be controlling the steam injection into the jacket. The other valve will be taking care of condensate removal from the jacket. 3. Resistance Temperature Detector.Resistance temperature detectors (RTDs) are sensors used to measure temperature by correlating the resistance of the RTD element with temperature. Most RTD elements consist of a length of fine coiled wire engrossed around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed try out to protect it. The RTD element is made from a pure material whose resistance at various temperatures has been documented. The material has a predictable change in resistance as the temperature changes it is this predictable change that is used to determine temperature. Page 18 For this application, we will be using a PT-100 RTD with a thermowell.The RTD will be mounted inside the thermowell for its protection from the steam inside the jacket. Thermowell also enables us to change the RTD with ease in case the RTD fails. 4. Pressure Regulator A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications. Since the header pressure is much more than needed for the application, the pressure will be reduced using a Pressure Regulator. The pressure needed for the application is 3 barg while the header can supply pressure 0-15 barg.To have a steady supply of steam and maintain the pressure and temperature, we will be using a pressure regulator. 5. Temperature Gauge with Thermowell Temperature Gauge is a device that measures temperature or temperature gradient using a variety of different principles. A Temperature gauge has two important elements the temperature sensor in which some visible change occurs with temperature, plus some means of converting this physical change into a numerical value. A temperature gauge mounted inside a threaded thermowell will be used. Since the temperature reading needed is of the food inside the vessel, the temperature gauge will be mounted on the side of the vessel just like the RTD. The thermowell will protect the Temperature Gauge rom steam inside the jacket of the vessel. Page 19 5. 2 Logic Diagram The first diagram displays the logic for controlling cooking process. With turning the device ON, it will start the procedure. According to the outcome of the decision block, it will decide and execute. Figure 4 Logic Diagram f or controlling cooking procedure Page 20 The algorithms presumptuousness below control the cooking of the food by maintain a specific temperature bracket inside the vessel. 3oC range is provided so that the solenoid valves wont switch ON/OFF at particular temperature which could result in damage. The second logic is for the condensate valve SOV2 which will be ON/OFF at regular intervals.Figure 5 Logic Diagram for controlling cooking and Condensate Valve Page 21 5. 3 Programming Most of the Programmable Logic Controllers use a different programming manner of speaking. The language used by them is called Ladder Logic. Ladder logic is a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. It is primarily used to develop software for programmable logic controllers (PLCs) used in industrial control applications. The name is based on the observation that programs in this language resemble ladders, with two vertic al track and a series of horizontal rungs between them.The previously shown logic will be made in Ladder Logic. It will then be downloaded into the chintzy memory of the Programmable Logic Controller. The PLC will execute the logic and accordingly it will monitor and process the parameters involved. In this project, the opening and closing of both valves and will be monitoring the temperature during the process. The program is made on proprietary software which is supplied by the vendor of the PLC. Every PLC make has specific software which is used to build the program and download the program into the PLC. It can also be used to change the process parameters in online mode. The software also provides offline simulation of the process.For data logging purposes, usually different software is used. The Ladder Logic for the project is under construction and will be finished by the time procurement of all the instruments is done. The parameters which need to be used in the logic will be found out during the processing of the procurement of instruments. During the period of procurement, the manufacturing of the vessel and designing the ladder logic will be done. Page 22 6. Completed Work and Implementation From the start, the project has been progressed according to the timeline. Now, all the instruments and material needed for the project has been indented and is in process. almost of the instruments have been dispatched.But for procuring the entire indent, it is going to take some more time. Meanwhile, since the Logic is available, the ladder program is being made and is approaching completion. Also, the manufacturing of vessel is in process and the vessel will be ready by the end of next week. After program is completed, some more time will be given to test it in offline mode and debug the program is any bugs are found. After all the materials are processed and the final values for the process parameters are found out, the project will enter the implementati on and testing phase. The entire infrastructure needed for the cooking vessel and the instruments will be constructed on the site.For different types of foods, the values initially found out of temperature and time will be used. If the parameters are not off by some amount, they will be rectified and the control will be made as efficient as possible. During the implementation, various temperature and time readings will be taken. For every type of food item, a detailed sheet should be made which will have all the parameters. According to the observed readings, new and better parameters will be decided which should reduce the cooking time and also increase the efficiency.

Logic and Logically Consistent Manner

1. What is logic? Is it beneficial for you to think in a logically consistent elbow room? The inherent ability to mentally compare and weigh two or more perceptions and to mentally conclude accurately what is the differences and/or similarities between each perception. logic is the science or art of exact cerebrate, or of pure and formal thoughts, or of the laws according to which the processes of pure thinking should be conducted and formation and application of prevalent notion. Logic is the study of information encoded in the form of logical sentences. 2.What if if the basic laws of logic much(prenominal) as below is not available to us? a. ) lawfulness of Identity A is A b. ) Law of excluded middle A or not A c. ) Law of non-contradiction A and not A both doesnt follow. 3. Why symbolisations are important in the domain of mathematics and in the growth of scientific knowledge? Symbols, in the most fundamental experience of the word, flock refer to anything which stands for something else (the signified). There could be a natural relation which immediately suggests the relation between a sign and signified or the relation could be arbitrary and chosen through some convention such as words in a language.Process of symbolization It is the replacement of something by a symbol for example one can replace Mass by m, a number by n. In almost all cases such replacement or naming is conventional and arbitrary. The process of symbolization should not and does not modify or distort that which it stands for. 4. Is communication effective without the logical connectives such as or, and, implies, not, if and only if? 5. Why we treat mathematical truth as certain? Why logic emphasizes on tautologies rather than contradictions?Logic is non-contingent, in the sense that they do not depend on any particular accidental features of the world. Physics and the other empirical sciences investigate the way the world actually is. That no signal can travel faster than the speed of light is depends upon the law of physics. If the laws were different, perhaps this would not have been true. While the principles of logic are derived using reasoning only and their validity does not depends on any contingent features of the world.

Bycatch Overfishing Regulations And Recovery Environmental Sciences Essay

One of the most urgent issues impacting piscaries today is finding methods of cut downing bycatch and keeping sustainable stocks. In this paper the author depart try to specify bycatch and discuss the Torahs regulating the pattern. The author pull up stakes besides discourse the commercial and recreational parts to the province of duress of the naval Waterss. Fishing patterns and methods of cut downing the sum of by-catch will besides be discussed. Without the cooperation of fishermen, province, federal, and world-wide authoritiess galore(postnominal) species of water snigger and fish will non last.Harmonizing to McCaughran by-catch is that portion of the winding returned to the sea as a consequence of economic, legal or personal considerations, add-on the maintained gimmick of non-tar vanquished species ( McCaughtan 1 ) . Bycatch ar fish, water bird, or shipboard soldier mammals that are caught by the way in all types of piscary cogwheel. They are caught because they are unable to travel fast plenty to get away or they may be attracted to the grow-on. There are many marauders in the ocean but we are the most unsafe marauders in the H2O. We are unsafe because we are limited merely by the bounds we set ourselves ( Hinman 3 ) . We prefer non to put bounds for ourselves that insure the sustainability of our oceans therefore these criterions must be set for us. These bounds are set so we usher out avoid the calamity of the place ( Wallace 1 ) . Puting these bounds is the duty of the National Oceanic and Atmospheric Administration ( NOAA ) and the National ocean Fisheries Service ( NMFS ) . The Magnuson-Stevens Fishery Conservatory Act in 1976 created 8 councils to rede NMFS on regional issues on piscary trouble. The jurisprudence claimed the Waterss within 200 stat mis of the seashore as the ownership of the United States but it neglected to set up any control over overfishing or habitat loss ( Safina ) . This act was amended in 1996 to inclu de home grounds and overfishing. On January 6, 2004, a reason regulation was submitted that stated National criterion 9 ( NS9 ) of the Magnuson-Stevens Fishery Conservation and Management Act, as amended by the Stainable Fisheries Act requires that fishery direction platforms include preservation and direction steps that shall, to the extent operable, minimise by-catch and to the extent by-catch can non be avoided, minimise the mortality of such by-catch. Implementing by-catch decrease device ( BRD ) demands for the eastern Gulf of Mexico would lend to run intoing that demand ( Federal Register 2004 ) .An extra amendment was added in 2007 that requires that one-year gimmick bounds and Marine protected countries ( MPAs ) be established ( NOAA Economics ) . The Sustainable Fisheries Act requires that when a stock does non run into the sustainable output a compulsory recovery program which includes a list of overfished species must be proposed ( Safina ) . Some of the reforms be in possession of been met with resistance by fisherman and with optimism by environmentalist. Fishermans sometimes stand to lose money with the exercise of new regulations and ordinances. The commercial fishing industry in 2007 was estimated to be a $ 28 billion a twelvemonth industry. An extra $ 25 billion a twelvemonth was spent on recreational Marine fishing and activities ( NOAA Economics ) .The tick off and by-catch species depends on where you are in the universe. What may be the contain species in the Gulf of Mexico may be the by-catch species in other countries. As new engineering has been introduced into the fishing industry more fish rich person been caught utilizing gillnets, bag Seines, want lines, shrimp spiller and other methods.Fig. 1. Most seafood in the U.S. is caught utilizing cyberspaces dragged behind boats, such as bag Seines, spiller and dredges ( NMFS, 2009 ) .This cogwheel enabled fishermen to catch the mark species and anything else in the Waterss. In 1 994 the estimated by-catch was 19.9 and 39.5 million dozenss of draw fish. A new estimation 10 old ages subsequently utilizing a new methodological psychoanalysis was much lower at 7.3 million dozenss. The cast-off sum is approximately 20 % to 25 % of the entire crop ( Wui 1 ) . These Numberss show that a mountainous part of the universe gimmick is discarded ( Davies et Al. 205 ) . By-catch can besides be defined as that portion of the gaining control that is discarded at sea, bloodless ( or injured to an extent that decease is the consequence ) ( Hall 206 ) . Catch may be discarded because of size, species, sex, or mortality. Other grounds are the gimmick may non be the right species, the quota has been reached, or they may be an illegal gimmick.The runt spiller piscaries show the greatest sum of by-catch. These Numberss differ depending on the root word and the method of computation. Some estimate the Numberss to be every bit high as 35 % for the universe gimmick ( Baum ) . Bycatch consist of sea polo-necks, late species of healthy center, Spanish mackerel, topographic point, croaker, beams, blue pediculosis pubis and many other species.In the 1970 s the ratio of by-catch to shrimp was 10 lbs bycatch to one lb of runt. Bycatch decrease devices ( BRDs ) have been mandated on runt spiller in the Gulf of Mexico. A BRD allows finfish and other by the way caught cosmoss to get away. From 1992 to 1994 there was a decrease of four lbs of by-catch to one lb of runt ( Robert ) . Shrimp spiller besides have turtle excluder devices ( TED ) fitted in them to let sea polo-necks to get away. Data shows that with these devices in the runt trawls the sum of some by-catch has been significantly reduced ( Robert ) . The devices have allowed a partial recovery of ruddy center, Spanish mackerel, king mackerel, and Atlantic croaker ( Louisiana Fisheries ) .Fig. 2. Two versions of runt spiller with BRDs. ( Fuls 16-18 )Bycatch is inevitable, even with the usage of BDRs. Data shows that there have been around 450 taxa document as incidental gimmicks in shrimp spiller. Attempts have been do to diminish the mortality of by-catch. One scheme was to integ sum up a fish oculus in the cyberspaces to let for fish flight. Fishermans besides could better the handling and release of the gimmick. The runt spiller is a type of cogwheel that continues to be studied and improved.Species English NamePercentage of total CatchLongspined scup15Brown runt9Atlantic croaker9Inshore lizardfish6Pink runt3Gulf stromateid3Lesser blue crab2White runt2Longspined swimming crab2Brown stone runt2Table 1 Top 10 species found in Gulf of Mexico runt spiller gimmicks ( Clucas 6 ) .Another type of angling cogwheel that continually produces high Numberss of by-catch is the distinct types of gill cyberspaces or miring cyberspaces. Driftnets have been called the walls of decease because big Numberss of non-target fish, marine mammals and sea birds become entangled in them ( Hi nman 3 ) .Fig. 3. Beginning Drift Net ( FAO-Fish 222 ) .Drift cyberspaces come in all sizes and lengths but the United Nations banned cyberspaces over 1.5 stat mis long in 1993, Data has shown that they catch legion mahimahis, sea polo-necks, and other blowers. There mark species is normally swordfish in the Atlantic but they besides catch tunas and sharks. Other finfish such as ocean sunfish, bluefin, giants, tuna, beams and others are besides caught by longlines. When living beings are entangled in these cyberspaces it is about ever fatal. Some cyberspaces have pingers attached to alarm unsuspicious quarry ( Martin 213 ) . Although some net fishing is pacify used the drift net piscary has been closed since 1996 ( NMFS 54 ) .Fig.4 Longline fishing cogwheel.The usage of longlines allows fishermen to catch a assortment of species. The come-on from the lines attracts sea birds, polo-necks, and other species of fish. legion(predicate) ocean birds eatage in countries where there are longline piscaries. The mollymawk has seen a diminution in population due to being caught on longline maulers. Longlines may be two or more stat mis long and have 100s of baited maulerss. These lines may travel unbridled for 24 hours ensuing in a high mortality rate for the gimmick. Once the birds are caught there is no manner for them to get away. Since they reproduce late in life and have a low fruitfulness they have become a threatened species ( Lewison 743 ) . The millstone has experienced a lessening in population due to longlines ( Hall 214 ) . It is hard to quantify the loss of millstone due to a deficiency of an perceiver plans. Other beings are affected by longlines. The sum of cast-off species in longlines in 1996 was estimated to be 196.6 metric dozenss of bluish marlin, 67.6 metric dozenss of white marlin, and 71.6 metric dozenss of sailfish . ( NOAA 54-55 ) . The grounds for high Numberss of by-catch are that the gimmick may non be the targeted species, it may be an illegal gimmick or it may non run into the legal size. The swordfish population has become stressed because of cyberspaces and longlines. In 1996 there were 579 dozenss of swordfish discarded. The Atlantic gar, a prized diversion fish, is frequently the by-catch of longlines. NMFS has enacted a program that protects this fish. The leader of a vas that hooks a billfish must let go of the fish every bit shortly as possible without taking the fish from the H2O ( NOAA 54 ) .One can non discourse by-catch without discoursing overfishing. Overfishing is the procedure of taking fish faster than they can refill themselves ( Gulfbase ) . The utmost sums of by-catch leads to overfishing. If the sum of by-catch is non reduced so stocks will go overfished. In many countries attempt decrease of the targeted and nontargeted species is attractive ( Wui 2 ) . The ruddy center may non retrieve unless there are bounds placed on the shrimping industry because the juvenile ruddy center is the by-catc h of runt spiller ( Wallace 84 ) . Bycatch decrease must be taken earnestly by the universe population.An country of concern in the subject of by gimmick and overfishing is that of the megafauna. Much of the megafauna by-catch has no economic value and has a high mortality rate. Having no manner to find the figure of beings that are being discarded, these stocks can worsen over clip without sensing. ( Lewison 588 ) . Leting the continued decrease in figure of anchor marauders such as billfish, sharks, bluefin tuna, bluish marlin, and swordfish will doubtless change the nutrient ironss. With fewer marauders there will be more quarry in the nutrient web. Harmonizing to Pauley if this continues we could see the prostration of some piscaries ( Hinman 2 ) . Alternatively of seeking to pull off one species the full ecosystem needs to be managed. We seem to be concerned about the big animate beings and non the animate beings they feed on. The remotion of one tropic degree will impact all degrees. Removing the larger and older species that by and large have a long lifetime and reproduce tardily in life will hold a annihilating consequence on the nutrient concatenation.Attempts are being made to seek to cut down the sum of by-catch in the fishing industry. Many fish would hold a higher endurance rate if they were released at a deepness related to their normal home ground. Fishermans are maintaining day-to-day logbook studies, utilizing unit of ammunition hooks alternatively of the traditional maulers, and utilizing pingers on cyberspaces. Other attempts proposed are to set up no-longlining zones, limit the figure of maulers allowed, and count dead discards against the fishermen as an inducement for set downing allowances ( Hinman 4 ) . Practices suggested to protect water bird would be to attach streamers to the lines to discourage the birds and weight the lines to increase the sink rate and carry the line deeper in the H2O ( Martin 214 ) . There have already been 170 0 Marine Protected Areas established in the Waterss of the United States to protect threatened species.The issues covering with by-catch and overfishing are legion. There are groups who oppose ordinance and groups who realize that without Torahs the piscaries will vanish. Even though some ordinances will impact the income of the fishermen, without ordinance at that place will non be piscaries. It is sad to read about the sum of cast-off by-catch. There are some states that utilize about all of their gimmick. As other nutrient beginnings become depleted and the universe population continues to turn, I am certain other states will happen utilizations for their gimmicks therefore extinguishing by-catch.

Animal Farm by George Orwell Essay

Animal Farm by George Orwell was trying to show the dis standardised of communism. Because the old form of government discontinue up being quiet similar to the new form. Orwell shows this by getting rid of Mr. Jones for mistreating the animals, and overtime Napoleon a pig comes to power, the same thing happened exactly with a different look. George Santayana wrote, Those who cannot believe the past are condemned to repeat it. This quote is similar to Orwells dislikes and the way he shows it in the book.Both the people and the animals go out the past and end up as before. The people are retributive thinking of getting freedom and the animals not being slaves but get the opposite. The animals like in page 73, which states, All that year the animals worked like slaves. This all adds to the tone of rebellious by the animals fighting in three battles to maintain their so called freedom, just like the people in WW2. In page 76 it states, had not these been among the earliest resolut ions. . t least they thought that they remembered it This quote show that the animals tried to remember about the seven commandments but they couldnt, so they had to forget any kind of idea and move on. This adds more similes that make Santayana quote true. George Santayana quote helps the reader take in why the pigs take advantage of the other animals. Since they saw that the other animals were not as smart as them. With Orwell tone of informative using actions and characters to represent a bigger picture in the world of political and to also express his theme adds a greater understanding to the story.

3 Paragraph Paper About the Novel Night Essay

Ellie weisel was the survior and author of the book Night. Ellie was born September 30,1928 in Sighet, Romania. He led a life representative of many Jewish children. Growing up in a small village in Romania, his world revolved around family, religious study, connection and God. Yet his family, community and his innocent faith were destroyed upon the deportation of his village to the concentration camp in Auschwitz in 1944.never shall I forget that night, the first night in camp, which has turned my life into one long night, sevensome cadences cursed and seven times sealed. (Elie Wiesel, Night, Ch. 3). Ellie Wiesel survived Auschwitz, Buna, Buchenwald and Gleiwitz. He was let free in 1945 and made his personal manner to Paris and started wrighting his first novel Night. During world war 2 many people were anti-semitism.Anti-semitism elbow room prejudice or hatred of, or discrimination against Jews for reasons connected to their Jewish heritage. Jewish people were satanic for the black pleg. They were also blamed for how bad the economy was. Hitler one of the most famous people during this time was using the jews as a scape-goat to get more votes. A scape-goat is just a group/ psyche you may put the blame all on.During world war 2 Jewish people were apply as scape-goats and at the time of all this if you were German you may have been anti-semitism. One of the most unforgettable events at this time were The deportation of the jews. The nazis had enough of the jews and were ready to do there final soulation every Jewish person with either that star david on them or had the letter J on there id was getting deportated to the concentration camps.See moreThe 3 Types of Satire EssayThe German authorities used rail off systems across the continent to transport, or deport, Jews from their homes, primarily to eastern Europe. German railroad officials used both committal and passenger cars for the deportations. German authorities generally did not give the jews getting deported food or peeing for the journey, even when they had to wait for days on railroad spurs for other trains to pass. Packed in sealed, suffering from overcrowding, they endured discriminating heat during the summer and freezing temperatures during the winter. Aside from a bucket, there was no sanitary facility.

Armed police guards accompanied the transports they had orders to require anyone who tried to escape.

Relationship between Theory and Practice Essay

Cognitive victimisation indicates harvest-time of the ability to mull over and explain. Lev Semionovich Vygotsky and Jean Piaget were greatly contributed to the cognitive splitment section of Psychology. The way small kids discover surrounding purlieu and psychologically develop plays a key role in their attainment shapees and skills. By learning the process of cognitive development supervisors give themselves a chance to great extent meet the requirements of the individual demands of separately separate child. Vygotsky and Piaget were considered to be constructivists.Constructivism is a method of training and learning based on the idea that learning is the consequence of psychological construction. To put it differently, children obtain knowledge making compatible their previous watch and new fresh information. Constructivists believe that learning is influenced by the situation in which a concept is delivered overly by childrens attitudes and values. An other common featu re between Vygotsky and Piaget is that they both think that the limits of cognitive development were set by societal influences.Unfortunately, this is the point where the correspondence between Vygotsky and Piaget comes to an end. There is a great disagreement between both theories of highly indicated scientists. Piaget claimed that mental growth came from activity. He believed that students learn by means of communication with their surroundings and that learning takes place after growth. On the other hand, Vygotsky held that knowledge takes place prior to the growth that fag end occur and that children learn because of history and symbolism.Vygotsky also claimed that students appreciate effort from their surrounding environment and from other people such as teachers and parents as well. Piaget did not consider the latter to be true. Vygotskys and Piaget concepts on cognitive development also have different attitudes. School systems and teachers have been practicing the cognitiv e development theories of Vygotsky and Piaget for rather a while. A good illustration of Piagentian training could be arranged in a preschool environment.through and through the preschool period Piaget considers students as being at the Preoperational level and as a consequence they are more likely to be self-centered. Consequently, it would be fair to discuss things with preschool age children from their own points of view as they go out feel their experiences are unique and precious. During classroom activities one student might say the glass of draw that another student brought to classroom to share is half empty while the student who brought the glass may consider the glass to be half full.Neither student is wrong in this example, the glass can be characterized by both descriptions but they may believe it due to the fact that each consequently likes or dislikes milk. Application of Vygotskys cognitive development possible action could occur in a maiden grade classroom. F irst grade children are frequently characterized by having varying stages of knowledge. Some students may already know letters and how to read while others are still making attempt to improve this process.An best option to assist the students who are not reading as well as the others includes ensuring these children aid harangue out a word when they get stuck while reading a text. With these preliminary considerations in take heed it would be well to conclude that cognitive development plays a central part in learning and thinking approaches of students. Vygotsky and Piaget provide valuable knowledge and data into the practical ways students learn and by employing these concepts it is possible to design a more advantageous learning context for each student.To get deeper understanding of Vygotskys theory it would be useful to visit the web-site http//www. newfoundations. com/gallery/Vygotsky. html. It suggests a number of approaches provided by in-depth studies and research of t he scientist. Vygotsky tries to invite answers to questions such as What is a human being? , What is knowledge? , What is learning? , What is society? , or Who is to be educated? . One more web resource that provides valuable insight into the researches conducted by Piaget is http//webspace. ship. edu/cgboer/piaget. html.To apply theory into practice we may observe that preoperational stage includes symbolism which means that the child already understands parallel notions of objects. For instance, to develop business skills from the early age it would be very useful to set an activity where objects replace corporeal things paper instead of money, books instead of TV-sets to be sold, etc. These two particular web-sites were chosen because besides the theory itself they also include practice and illustrations. They describe how the results of the studies may be applied in learning and command processes.

Border and Coastal Security (Criminal Justice) Essay

hardened Border puzzle and Open Border Paradox. The Hardened Border Paradox refers to the situation when tougher border controls fail to achieve their objective stop illegal migrants and smuggling. Instead, it is argued, these tougher controls get to an atmosphere ripe for spread of miserable activity. Jeane J. Kirkpatrick, Senior Fellow in National Security Studies at the Council on Foreign Relations, in his written testimony before a hearing of the Committee on Foreign Relations, joined States Senate noned that draconian measures to police the border invariably provide incentives for informal arrangements and criminal conspiracies to overcome cross-border barriers to commerce and labor movements.There appears an industry for helping illegal migrants, whereas the cooperation of law enforcement bodies is reduced when atomic number 53 side unilaterally pursues strict policies. The border becomes more chaotic, and tough regulation creates a invite for those who are in the busin ess of arranging the illegal crossings (Kirkpatrick, 2004). This paradox can be resolved by combating illegal groupings and promoting cooperation at the border between political science on both(prenominal) sides.The Open Border Paradox includes the need to combat the movement of terrorists and smugglers across open borders without damaging the free flow of goods and services that benefits the economies of both nations. This paradox exists, for example, on the US-Canadian border where the flow of goods and services is in dependence on anti-terrorist measures.To overcome this paradox, authorities from both sides can create special projects targeting terrorists without jeopardizing trade flows. Kirkpatrick in his testimony points out the example of a bi- bailiwick Integrated Border Enforcement Team (IBET) created on the US-Canadian border to overcome smuggling in 1996.Is it cost trenchant to spend millions and millions of dollars in an effort to stop a handfull of people who are boun d to terrorize the United States?Counteracting the bunch of people bound to terrorize the United States is worth millions of dollars and perhaps even more. This number is adequate with the devastating impact September 11th and other events had on the development of the American economy and issue security. Efforts to combat terrorism within the United States are also costly.The negative effect of terrorist activities on the frugal activities of Americans can hardly be overrated. Terrorism poses a risk to the United States and all of its business. Foreign partners contemplating a deal with US companies will be more reluctant to do so if they perceive the narrate as being in continuous danger of an external attack. This means loss in collateral be from dangers to the national security, with the effect similar to that political inst business leader in developing nations has on their ability to attract and retain direct foreign investment.The costs of failing to keep the terrorists o ut are indeed serious issues that pass water to be addressed in order to prevent the possible danger to the economy. In this way, these efforts are similar to risk management in business. The risk averted may never materialize, and all the costs seem to have sunk in vain however, if the risk did materialize, the impact on business would have been much greater.Speaking of the need to avert a terrorist attack through anti-terrorism campaigns, one need not forget that it is not only economic prosperity that is at stake. The negative impact on the tonicity of lives of Americans from September 11th attacks cannot be measured in dollars alone, for here one must factor in the pain, the grief, and the fear that affected even those who only saw the attacks on TV. The government has to deliver public goods to the people, and national security is one of them. Therefore, spending large sums on anti-terrorist measures is a sound idea as vast as helps to prevent the terrorists effectively fro m getting into the country and perpetrating their crimes.
