Art History - Essay Example According to this movement, reason and logic led people into war and therefore they were against capitalism. Fountain is one the greatest Duchamp’s works and this piece of art is dated 1917. This piece of art is well known for the production of readymade or found objects of visual art. It is also important to understand that this piece of art has a close relationship with the dada movement. As already mentioned above, Dadaism was against the strict logic and reasoning and productions like the fountain was meant to change the focus of art from the traditional visual to mental. Theo van Doesburg is also one of the Dadaist artists who had similar opinions of changing the focus of the traditional art to modernism. According to this artist, art was not meant to just please the eyes but also to appease the mind. His works closely resembles Duchamp’s work of cubism. The two artists based their works on change of ideologies as they argued that lack of change in ideology is what resulted into the First World War. Their main aim of art was to show retaliation against capitalism in most countries across Europe and America. Theo van Doesburg made large drawings, writings and other studies regarding large glasses. This artist desired the accommodation of modernity with his style commonly used in modern industrial products. This is also similar to Duchamp especially his work on the fountain. The urinal is commonly used in the toilets. It is also important to understand that the formation of glasses and tiles as pieces of art is majorly influenced with these two artists. Besides this Doesburg was also much concerned about alphabetical designs something that is argued to be an influence from his witty chess game (Baljeu). He is reported to be a lover of chess and this influenced most of his art work. A good example is the formation of the vertical word of zig-zag in 1931. The artists aimed at stripping words their

Nano - Assignment Example Tompkins has been titled the CEO because his background closely fits the position. He is likely to be doing more work than the other founders. Since he is doing more work he deserves a different salary and equity level. The other founders are fair with the equity but not fair about the salary that Tompkins receives. The decisions made regarding split equity and compensation is unfair and leaves no room to share equity amongst other employees. Without being able to share equity amongst other employees, the new employees may not be as driven to get the company where it needs to be. The founders are the creators of the company and share in ownership. All though they may share in ownership it does not mean that they should share equity and compensation if there job duties are not the same. A change is equity and compensation needs to be made to create a real fairness and ability to offer equity to other employees. The size of the founding team is five men that are all from the same company. Don Rupert is the head of AMSL. He is a co founder of NanoGene. Will Tompkins is a bio chemist and founder along with three other scientist and biologist. Mark Masterson and Ravi Rhoota were former AMSL scientist and an important asset to NanoGene. Gary Garfield who was also important to NanoGene is a doctor in biology. Each founder is vital to NanoGene in a way that the type of development for NanoGene requires each founder to make it work. Having five founders starting up a company can cause problems early as well as later on in the company life. Having five founders requires the need to receive acceptance from each of the five founders each time an issue arises. It is unlikely that all five founders will agree on each issue. When issues come up of importance it is likely that a vote will need to take place. Being a founder of a company is an important role. Founders are the

Intelligence Reform Essay Example | Topics and Well Written Essays - 750 words

Intelligence Reform - Essay Example After World War 1, America intelligence hard work paid attention on code breaking against Germany and Japan. In 1941 president Franklin Roosevelt established the first peacetime civilian intelligence after discovering that it was inevitable to escape involvement of the world war 2.the offices were developed to manage the activities of a number of agencies. Nevertheless, after the Japanese bombed Pearl Harbor the United States experienced its mostly expensive intelligence disaster (Zegart 25). The intelligence failure because of assessing â€Å"misconceptions, collection gaps, bureaucratic confusion and well-planned Japanese denial and deception† resulted to the development of a larger and more varied agency in 1942 (Calabrese 11). The US intelligence agency faces the challenge of widespread lack of trust in its power to undertake its mission competently and legally. Existence of increased terror group like al Qaeda has been a major challenge for intelligence policy makers (Kantor 35). The ability to control any source of information retrieved is also a major pitfall. Intelligence agency need also to change its old tactic of viewing things instead it needs to incorporate the developing technology to counter enemies. The September 11 attacks necessitated the intelligence to reform its tactics to counter other terrorist attacks. The attack was termed as a major failure for the intelligence team therefore reinvention and revitalization techniques ought to be embarked (Calabrese 14). The intelligence reforms have also embarked on techniques that involve counterintelligence missions. The techniques involve finding out loopholes within the intelligence team to ensure past mistakes are not repeated and terror attacks are prevented. In the past intelligence involved speculation about problems or what was anticipated to happen. Evidence of information were hidden and

Prison Corruption and Control Essay Example | Topics and Well Written Essays - 500 words

Prison Corruption and Control - Essay Example For corruption to occur, it requires discretionary powers and a lack of accountability (World Bank, 1998). If accountability is present in any shape or form, the likelihood of corruption becomes reduced. In the same manner, a civil society as well as an organisation within that civil society can reduce corruption if it focuses on accountability wherever there are discretionary powers handed over to a given party (Von Muhlenbrock, 1997). For example, prison wardens may have discretionary powers to a large extent in terms of how prisons are supposed to be handled and how they are to be governed. This discretion gives them great power in managing prisons and they are able to maintain control of quite a few situations where not having discretionary powers would lead to inefficiencies in the system. Even a prison guard can be given discretionary powers and such powers are required for him/her to perform his/her duties. At the same time, all individuals working in a prison have to be made accountable for their actions. Situations where it is suspected that discretionary powers were misused, have to be brought to light and if the individual is found guilty of misusing his/her power, appropriate punishments need to be given out to that individual. Unless the process of holding people accountable for their use of power is established, discretionary power would lead to some level of corruption (Von Muhlenbrock, 1997). As long as accountability remains in place, the chances of prisons, societies even business enterprises becoming corrupt remain minimal (SMH, 2006). The issue of accountability is not limited to social bodies such as prisons and hospitals. On a larger scale it also applies to countries and nations who may use their discretionary powers to establish their own controls over a region or over other countries. Even in such cases, if the country can be made accountable for its actions, the chances of misuse of power become minimized.

Thermodynamics Lab Essay Example for Free

Thermodynamics Lab Essay Purpose: The purpose of this lab is to determine the identity of an unknown metal, and to prove whether the laws of thermodynamics hold when determining this identity. Using the accepted specific heat of water (4186 J/kg  · oC), heat flow between two different sets of water though the conduction of an unknown metal can provide useful data in determining the identity. The heat transfers can be calculated to approximate the specific heat of the unknown metal. When heat is transferred to an object, the temperature of the object increases. When heat is removed from an object, the temperature of the object decreases. The relationship between the heat (q) that is transferred and the change in temperature (DT) is: q = mCDT = mC  · (Tf Ti). After the specific heat of the metal is found, it can then be compared to known specific heat values of various metals, which in turn will allow for a probable identity of the unknown metal to arise. Hypothesis: The identity of the unknown metal is aluminum. This can be inferred from the unknown metals appearance, which resembles aluminum it its color, light weight, and luster. The laws of thermodynamics will hold when determining the unknown metal. The laws of thermodynamics must apply in order for heat flow to occur during the experimentation. Materials: The materials used in the lab were two calorimeters (insulated, Styrofoam containers), an unknown metal in the shape of a wide horseshoe, two thermometers, a balance, water, a beaker, and a Bunsen burner. Procedure: 1.Measure the weight of the Pyrex beaker, and then pour 200 mL into the beaker. Weigh the beaker filled with water. Record both weights to find the weight of the water by itself. Let this mass of water be labeled 1. Next, pour the water into one of the calorimeters and take the temperature of it. This temperature should be the room temperature and the same as the unknown metals temperature. 2.Pour 200 mL of water into the beaker and weigh the beaker filled with water. Record the weight. Let this mass of water be labeled 2. 3.Use the Bunsen burner to heat up the 200 mL of water in the beaker to 75o C. Then pour the hot water into the other calorimeter. 4.Set-up the calorimeters by placing the thermometers and the unknown metal in their specific places. 5.Record temperatures of both calorimeters every minute until thermal equilibrium is reached. 6.Clean and return all materials and dispose of any waste. Conclusion: The graph indicates that heat flow did undergo during the experimentation. The cold water increased in temperature, while the hot water decreased. The two liquids underwent changes in temperature until they both reached thermal equilibrium. This thermodynamics law is called the Zeroth Law of Thermodynamics. This law basically states that two bodies will naturally reach thermal equilibrium when in contact. The First Law of Thermodynamics was obeyed as well. Only heat from the warmer body went to the colder body. Heat only travels in one direction, from the hot to the cold, as can be seen from the graph. My hypothesis of the unknown metal being aluminum was correct. The results of my lab showed that the unknown metal was aluminum, and later it was said that the metal had in fact been aluminum. The lab calculations went well. The values were somewhat disparate however. For example, the specific heat was found to be 1200  ± 110 J/kg  · oC, but the actual specific heat of aluminum is 900 J/kg  · oC. This difference can be attributed to the imperfect insulation of the calorimeters. Some heat must have been lost during the experiment, which may have caused a distortion in values as a result. Also, the metal was exposed to the outside air, and likely lost some heat to the air. Overall, the lab was a success. The only improvements I would suggest are to have better insulators and more precise instruments. Better insulation would yield improved results. The metal, which was transferring the heat, should have been insulated so that heat could not escape during the heat transfer. More pr ecise instruments would cut down on the uncertainties, which then would allow for better and more accurate results.

Spectrophotometry Essay Example for Free

Spectrophotometry Essay Potassium permanganate (KMnO_4) is commonly used as an oxidizing agent and in this experiment, it is used as both the titrant and indicator. A standard of potassium permanganate solution was prepared and computed to be 0. 02235 M and was used to titrate a sulfuric acid solution wherein the sample salt was dissolved. The solution was heated to 90Â °C then titrated until a light pink colored solution was obtained. The experiment focused on determining the percentage of Sodium oxalate (Na2C2O4) in the sample and at the end of the experiment it was found to contain 49. 45%. Experiment 9 focuses on determining the different concentrations of potassium permanganate solutions by finding its absorbance through the use of spectrophotometer. Four known concentrations were prepared; 2. 5 x ? 10? ^(-3) M, 6. 25 x ? 10? ^(-4) M, 1. 25 x ? 10? ^(-4) M, 6. 25 x ? 10? ^(-4) M. The solutions were placed on the spectrophotometer to determine absorbance together with the unknown. Distilled water was placed before each trial to ensure the accuracy of results. Determining the concentration of the unknown sample was done by drawing a graph of the concentration against the absorbance and was found to be Introduction Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. The basic principle is that each compound absorbs or transmits light over a certain range of wavelength. This measurement can also be used to measure the amount of a known chemical substance. Spectrophotometry is one of the most useful methods of quantitative analysis in various fields such as chemistry, physics, biochemistry, material and chemical engineering and clinical applications. A spectrophotometer is an instrument that measures the amount of photons (the intensity of light) absorbed after it passes through sample solution. With the spectrophotometer, the amount of a known chemical substance (concentrations) can also be determined by measuring the intensity of light detected.

Climate Change Effects On Water Resources Environmental Sciences Essay

Climate Change Effects On Water Resources Environmental Sciences Essay The last two decades climate change is increasing due to the change of human activity such as cars, planes, factorys and other sources we use that adds greenhouse gases to the atmosphere. Because of these human causes the earth is heating up. One effect that climate change has is the effect the change will have upon human water freshwater resources. I believe that climate change will have an effect on human water resources because of the close connections with the hydrological cycle, the raising temperature will increase in floods and droughts that will lead to the demand on more freshwater resources. Climate change has close connections with the hydrological cycle. The hydrological cycle is located in the earths hydrosphere this is the area in around earth which holds all the water. The water is moved around the earths hydrosphere in a cycle. The hydrological cycle is moved in five different steps evaporation, precipitation, condensation, runoff, collection and infiltration. The as you can see in Figure 1 the hydrologival cycle all starts of with evaporation this is the change of liquid water to water vapour. The next step is condensation this is the process of changing water vapour, from a liquid and then to form clouds as you can see from the clouds in figure 1. This process can be notice for example when you look out for dew on the ground in the morning. As the clouds you see in the sky move around earth spreading the water vapour from place to place. The clouds become over loaded with moisture so they have to release the overloaded moisture. They release the moisture by a pr ocess called by precipitation which is usually rain, hail or snow. Infiltration occurs they when all the precipitations lay on the ground. If there is to much precipitation on the ground this becomes runoff. Runoff stays on the earth ground and runs into streams, rivers, lakes and oceans. So when the precipitation run into the these streams, rivers, lakes and oceans this process is called collection. As infiltration, runoff and collection are being processed, the sun is causing a the cycle to return back to the begaining of the cycle to the process called evaporation.Sunlight heats up the liquid in streams, rivers, lakes and oceans. The warm air rises upwards into the atmosphere and becomes the vapour involved in condensation. Without this process life on earth would be impossible. Freshwater that we use in or day to day lifes usually comes from Aquifer, Streams, Rivers, Lakes. Aquifer are constructed when rocks of the upper part of the earths crust contain holes or pores. Theses holes are big or joined together so that water can flow through them easily. This is a part of rock that is easy for water to pass through known as permeable. Streams usually get most of its water from runoff, rain and melting snow. A stream is formed when the rain and melting snow met at the same place and get into a line of channel. Streams usely flows into lakes, rivers, aquifer and seas. Rivers are a natural stream of freshwater resource. Water within the river is generally collected from precipitation through surface runoff, groundwater recharge, springs and the release of stored water in ice and melting glaciers. Lakes are usually filled with deep freshwater or salt water. Lakes are inland usly on mountains areas and are not part of the Ocean. They are filled by rivers or streams that connect to them. Some Lakes can be man made and are constructed for industrial or agricultur al use and even for hydro- electric power or domestic water supply. Water is one of the most importent inputs the human body needs for us humans to cope with everyday life . We need it for so many things e.g. health, growing food, irrigation, industry. Despite the importance of Freshwater Resources decreasing, we are beginning to take the freshwater resources for granted. Most of the freshwater we use is wasted and polluted. Because the hydrological cycle temperature is rising it will lead to a change in the horological cycle, This will have an impact on the weather. The dry seasons will become alot more dryer and the wet seasons will become alot more wetter. Leaving us with more floods and droughts. This change will therefore will impart the availability and quality of water. Some of the countries on this earth already have a hard enouch time getting water because of increaseing industrial pollution and population growth. Climate change just adds to the problem to the quality of water, which in some parts of the world the reduce rainfall and rising temperatures decrease the freshwater. By the year 2025 most of humans living in countries with poor water quality levels will increase from approximately 34 percent (in 1995) to 63 percent.R K Pachauri (2005) The change in accessing water stressed areas will have a potential conflict. As there will be a pressured demand on freshwater because of household, agricultural and industrial uses. These conflicts will occur in water stressed areas fighting against areas of natural springs and rivers as well as this it will lead to conflict on boundary areas for example the region of Northern Kenya and the Samburu is having to cope with the changing patterns of rainfall and dry periods which with other pressures on the natural resources are leading to increasing conflict among tribal groups over access to scarce water.Smith (2006) 2 Discussion Most of the earth has 70% of ocean. While just 30% of the earth is land. Around 84% of the worlds population is living on dry land. Humans are trying to fix this by reconstruction the hydrological cycle system by building dams and creating waste water treatment plants etc. These elements will provide water for agriculture, household, Industrial, environmental and other uses. But these changes will also lead to some defects in years to come. India is one of the most effected by climate change. The snow ice caps of the Himalayas is experienceing less snow because of snow melt. The glaciers is melting and there is signs of increase flooding. The increasing rising temperatures is starting to dry up the rivers. The Himalayas holds the largest amount ice on the earth. Researchers have figure out that there is a strong combination between snow and the temperature. In recent years the Himalayas have experienced warm periods in the years between 1960- 1990, causing a reduction in snow fall. Glaciers has been watched by researchers in the the past years. The United Nations climate report predicts by 2035 some Himalayan glaciers will disappear with the rising temperatures. Because of the glaciers melting the melting ice will run off into rivers such as the Indus, Ganges and Brahmaputra rivers and some tributaries coming from the Himalayan ice field. This will cause flooding to riverside cites e.g. Varanasi, Kanpur and Patna. These citys have a population of millions and have already experience floods during high monsoon season and it will be ongoing. Flooding will also cause interruption for the farming areas in northern parts of India and cause damage to the roads and rail way line. The dams such as the dams in Kosi ans Sutlej could over flow causing more destruction to cornfields and settlements. When the point of no ice is reached by 2035 the ice melting will have either stopped because of a solution to climate change or be dried up because of the continued temperature rising. If the ice does start to minimise the river will become weaker and dryer during the monsoon mouths and summer. As the earths temperatures rises from about 14 degrees C based in 2000 to a estimated 19 degrees C in 2100 the following effects will be cause by the increase; Agricultural, Household, Industrial, Environmental and health sea levels will rise to an estimated 3.9 in to estimated 35 by 2100. Some parts of the coastal cites around India e.g. Mumbai, Chennai, Kolkata and other parts of the world will be underwater. Even most of the island around India will be covered in water. The island of Lohachara is the first island in the world to be covered in water due to climate change. The island is located on the southern edge of the Ganges delta in the bay of Bengal. Its 10,000 residents became the first refugees created because of climate change. There is a group of 27 island called Lakhadweep around the Arabian sea off the coast of south Indian state Kraal. They have a population of about 61,000 people living on them. The low lying islands are in huge danger of being covered in water as well. India is one of the world biggest countrys that effects the greenhouse effect. With the increased temperatures they will create a increase in precipitation. Rising the process of evaporation resulting from warmer sea temperatures in the Indian ocean and Arabian Sea will increase that destroy process around the west Indian Rajasthan Desert As well as the water resources being shorten because of climate change there is also another problem and that is that usually boundary countries sometime share the same water resource. There is some indentation that there has been conflict over freshwater shared by two or more countries. Freshwater is very important to all the worlds Humans activity, including the Agricultural, Household, Industrial and Environmental. But bad management and the impact of climate change can lead to tensions between different countries. For some years the counties such as India and Bangladesh have encountered conflict on river resources. It all started In 1993 when India and Bangladesh came under pressure when the Ganges River started to reach its record lows. Because the water level was low it affected Bangladesh agricultural and killed most of its crops. In October 1995, The Prime Minister of Bangladesh addressed the United Nations(UN) .The prime minister called India ¿Ã‚ ½s share of river water resources  ¿Ã‚ ½a gross violation of human rights and justice. ¿Ã‚ ½ India ¿Ã‚ ½s establishment of the Farrakka Barrage which is a barrage built near the border of Bangladesh. The barrage was build was to separate water for the Calcutta port. But Bangladesh says that because of this separation it has resulted in falling water tables and greater water resources for Bangladesh. India has a different view of the issue. Indian leaders says that Bangladesh was wrong in describing this issue. Bangladesh has asked India for a  ¿Ã‚ ½minimum guarantee ¿Ã‚ ½ agreement which will give Bangladesh a minimum flow of water. In 1996 India and Bangladesh agreed in the agreement then the  ¿Ã‚ ½Treaty on the Sharing of the Waters of the Gang ¿Ã‚ ½ was signed. Some political leader were unhappy about the agreement. But it was accepted my most political leaders. Since the treaty Bangladesh continues to have a number of problems. Some of the agreements that was agreed in the treaty have not been met. How are we going to fix this problem is the question we need to ask ourselfs I can see from my research that some efforts are being made to improve management in freshwater resources. Different organiseions have been developed to help the mather of climate change for example, the United Nation(UN) have organised the first water conference to take place in 1977 and developed an action plan to take action on the improved management and development of water resources and the UN designated 2003 as the international year of freshwater resources. The mission of the organision is to increase awareness of the importance of freshwater use, management and protection, provide an opportunity to change the implementation of the principles of integrated water resources management, use the year as a platform for promoting existing activity and spearheading new initiatives in water resources at the international, regional and national levels, and Launch the world water development report at the thir d world water forum in Kyoto. The World Summit on Sustainable Development(WSSD) 2002 has emphasised on the development of an integrated water resources management and water efficiency plan.DEVELOPMENT (2003). Global Water Partnership(GWP) Is a network of agencies and intuitions to promote  ¿Ã‚ ½integrated water resource management ¿Ã‚ ½ in developing countries. It facilitates the exchange of knowledge, experience and practise related to water resources management.Partnerships (2010). World Water Council(WWC) is an international think-tank for water issues. It objective is to  ¿Ã‚ ½increase advocacy for improved water resources management ¿Ã‚ ½. WWC has been organising the World Water Forum(WWF) bi-annually. The 3rd Forum was held in Japan in march 2003.Council (2010). European Water Association Act as a focal point for the exchange of information related to water and water activities.Association (2010) 3 Conclusion I can conclude that because of climate change and the hydrological cycle it is having a slight long term effect on human water resources. I can see that it has close connections with the hydrological cycle. Because of this it will increases flooding, create dry lands and encounter conflict within countries. More acceleration to the hydrological cycle may result in more severe weather and extreme conditions.Anne E. Egger (2003) If we dont address this issue there will be further more problems in the future and lead to even more droughts and flooding. According to the Comprehensive Assessment Of Water Manage in Agriculture, one in three people are already facing water shortages(2007). Almost one-fifth of the world ¿Ã‚ ½s population, live in areas of physical scarcity. Climate change has a close connection between hydrological cycle. Rising temperatures will increase the changing liquid to vapour and lead to the increases in rainfall and snowfall. Because of this the overall supply of freshwater resources will increase, Droughts and floods will happen more frequently and changes in snowfall and snow melt are expected in mountainous areas more frequently. Reading about climate change has made me release that we take our freshwater for granted and dont think about what will happen if we lose the freshwater. Will we have to introduce water charges maintain better water systems.
