Photochemistry of Ruthenium Complexes - Essay Example In packed systems, this will lead to two events: the transfer of excitation energy or the transfer of the electron itself to a neighboring complex that has a lower energy level. Eventually, the series of reactions will result in the production of NADPH and ATP. The net photochemical reaction involves the splitting of water, which is the ultimate electron donor, to  ½ O2, 2H+ and 2 electrons (summarized in Mathews and Van Holde). The photochemical reaction in photosynthesis was the basis for developing inorganic systems that can make use of the high potential of solar energy. This is especially important now that supply of fossil fuels like gasoline and diesel is affected by political, climate and environmental events. The recent erratic changes in price and supply coupled with the high demand for fossil fuels increased the search for renewable and cheap sources of energy. Sunlight is free and harnessing solar energy is one of the main objectives for developing photochemical technologies. In this context, ruthenium complexes have very important roles to play. Ruthenium complexes have long been studied for their many uses in the energy, chemical and lately, in the medical industry. Ruthenium (Ru) is a rare transition metal which falls under the platinum group in the periodic table of elements. Its atomic number is 44, and has oxidation states ranging from -2 to +8 but the most common are +2, +3 and +4. In its elemental state, ruthenium is easily oxidized by air to form ruthenium oxide, RuO4. It does not react with acids but easily reacts with bases and halogens. Small amounts of Ru are added to platinum, palladium, gold and titanium to produce hard and tarnish-resistant alloys. Ruthenium, as part of an alloy or when complexed with other compounds, is also utilized in other applications like catalytic reactions, electrolytic protection, optic sensors, microelectronics, organic and polymer synthesis (Dragutan and Dragutan), anti-cancer agents

Global Food Production Challenges

Global Food Production Challenges Introduction It has been observed that In spite of the fact that the food production has increased almost twice in the last few decades, but there are people who are insecure of the food conditions and do not get enough nutritious food to eat (Wu et al. 2011). As per the world population data the people who do not get adequate nutritious food to eat has reached to the extent of 870 million in 2013 (FAO et al. 2013), also it has been stated that, by the end of 2050, food production globally has to increase by 70 to 100 percent so that the total world population can had nutritious food to eat. (Bruinsma, 2009; Parry and Hawkesford, 2010; Zhu et al., 2010) It is also necessary that preventive steps are to be taken so as to reduce the global warming and greenhouse effect and ozone depletion. Population History and growth As per the UN population prospects, the population of world is expected to grow by 34 percent from 6.8 billion to 9.1 billion in 2050, so this increase in the population is the main reason for increased demand of the food. Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat (2007) It has also been noted that China and India, are the worlds most populated countries, both are bhaving more than 1 billion inhabitants; each has sustained once a year gross domestic product (GDP) growth rate over 10 years ago that is among the worlds highest — 9 percent for China and 7 percent for India. As per the National Defense Research Institute (2011) although the population of India is lesser than that of china, but at the present scenario population growth of India is 1.55 percent yearly more than double Chinas 0.66 percent. It has been estimated that by 2025, the total population of India will be equal to that of China thus making India most populous country in the world. Also it has been noted that the population of India will continue to increase till 2050, while the population of China is expected to peak at about 1.4 billion in 2026 and will de-grow after that . (Figure 1) Figure Total Population Sizes, China and India, 2000–2035 ( http://www.rand.org/pubs/research_briefs/RB9598/index1.html ). Global Food systems Global food systems consist of production and supply of foods and its consumption.  Figure 2 describes the overview of this food system. On the basis of the national level, supply is basically a function of national production and imports minus exports. The difference between supply and consumption is the gap caused by losses in the food chain. Global food system Figure 2:  http://www.sciencedirect.com/science/article/pii/S0195666310005118 Global food Production In the year 1961, FAO gave information on the annual market supply to all the countries in world, for the production of agricultural commodities. (Gerbens-Leenes, 2010). Global Food Consumption: Food consumption patterns are the repeated arrangements of consumption, characterized by types and quantities of food items and their combination in dishes and meals, (Gerbens-Leenes Nonverbal, 2010). Food consumption pattern is based on certain factors like availability, tradition, culture and income effects. Land degradation Land degradation is basically temporary or permanent decline in ecosystem function and productive capacity. It can be destruction or deterioration in health of terrestrial ecosystems, which affects the biodiversity, natural ecological processes and ecosystem resilience, it can also reduce the biological/economic productivity and complexity of croplands, pasture, woodland, forest, etc. This can result to numerous factors like anthropogenic (human-related) activities such as unsustainable land management practices and climatic variations. The accelerated degradation is normally linked with human alteration of the environment. Degradation process can be deforestation and desertification. There are different cause for the degradation of land and they are soil erosion by wind or water, natural conditions, topography, weather/climatic conditions, high intensity rainfall, natural hazards, unsustainable agricultural practices, habitat alteration. (http://www.cyen.org/innovaeditor/assets/Land degradation module.pdf) Land desertification Desertification is one of the most serious environmental problems on a global scale. It is a biophysical edaphic, climatic and geographical feature of the region Ying zhong XIE, (2014). Desertification is basically the degradation of dry land ecosystems by variations in climate and human activities. Worldwide desertification has affected the life of millions of people who depend on the dry land ecosystem. It has been observed that the dry lands are because of the shortage of the water. Thus, desertification is one of the main environmental threat today and a barrier to basic human needs in dry lands. As per (Jason P, 2012) the pervasive but untested desertification redistribution is because of loss of grass cover, this can have global relevance for human-environmental systems which can be at risk due to current or potential desertification. Agriculture Disease Measurement of Disease and Its Effect on Yield Plant diseases are those that either kill the plant or reduce the ability of a plant to survive, produce flowers or fruit. They are caused by micro-organisms normally referred to as pathogens; which include fungi, bacteria and viruses, although it is very difficult to measure the severity of plant disease. There are certain diseases but major plants disease include in which the leaves are not shaped properly; the symptoms cannot be identified and they can be from a few isolated lesions to also collapsing of the entire plant. Moreover there is no relationship between measures of symptoms and the failure to reach achievable yields . Thus it has been observed that the measurement of yield is highly controversial. However, the relation of plant disease to yield is not be very clear and it will need some proper measurement. (annualreviews,2014) Global Water Crisis It has been noted that because of shortage of water supply there has been a decline in irrigation. Water is very important and is used for crop cultivation in all regions of the world.( Hanjara and Qureshi , 2010). There has been seen an increased competition for water resources among all the sectors, regions and countries. Moreover 40% of the populations in the world live in regions that directly compete for water resources. Water is very important for irrigation, drinking and for other things thus water is very important. A major concern to maintaining future water supplies is the continuing over-draft of surface and groundwater resources. As a result, there is decline in available surface water and groundwater for irrigation. It has been observed that climatic change has an impact on the global food security and change in water and food supply. Moreover this change in the Climate can affect the production of agriculture and food security by altering the distribution of rainfall, and also the availability of water, land, capital, biodiversity and terrestrial resources. Furthermore, this change in the climate will also have an adverse impact on food and crop productivity, which can affect food security ( Hanjara and Qureshi, 2010). It has also been seen that the global warming can increase yields which can be due to negative effect of fertilizer, by rising presence of carbon di oxide present in the atmosphere, but this can have a negative impact on poor countries. Greenhouse effect on Carbon dioxide An increased level of carbon dioxide in the atmosphere is the main reason for increase in the global warming. As per certain studies at the Carnegie Institution for Science, in some regions more than a quarter of the warming result from increased carbon dioxide it is due to its direct impact on vegetation. Thus this increase in temperature and also an increase in the carbon dioxide levels have a heat-trapping greenhouse gas. For scientists trying to predict global climate change in the coming century, the study underscores the importance of including plants in their climate models. Plants during the photosynthesis take carbon dioxide out of the atmosphere, but they also have some other effects, like change in the rate of evaporation from the land surface. Thus the effect of carbon dioxide as a greenhouse gas have been well known as pointed out by Caldeira. Moreover there is no doubt that carbon dioxide decreases evaporative cooling by plants and that this decreased cooling adds to gl obal warming. Greenhouse effect of higher temperature The greenhouse effect is basically when the short-wave solar radiation heats the surface of the Earth, and this energy is radiated back through the Earths atmosphere as heat, radiations of wavelengths 5-30 µm is absorbed by water vapourand carbon dioxide, which in turn radiate it, thus heating the atmosphere and land and ocean surface. This happens on its own and is natural and this is what is the reason that keeps the Earth habitable. Greenhouse keeps the average surface temperature would be about minus 18 °C, which is same as on the moon. There is a difference of some 33 °C substantially to natural levels of water vapour (60%, or more including clouds) and carbon dioxide in the Earth’s atmosphere. In respect to enhancing the greenhouse effect, the particular issue is focused in the 8-18 µm band where water vapour is a weak absorber of radiation and where the Earths thermal radiation is greatest. As methane is stronger greenhouse gas because it has more atoms in the molecule than CO2. The radioactive effect is caused by infrared absorption, and molecules with more atoms absorb more infrared energy. IR absorption is by the electrons that bond between atoms in a molecule and the way those atoms vibrate. Greenhouse effect to Climate variability This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2has increased since the Industrial Revolution: (http://www.globalissues.org/article/233/climate-change-and-global-warming-introduction#TheclimatehasalwaysvariedinthepastHowisthisanydifferent) Increase in Pests And Disease As per a report in the journal Science in June 2002, it says that there is an alarming increase in diseases, this can be due to change in climate. Accordingly, it has been pointed out by authors that a â€Å"Climate change is disrupting natural ecosystems in a way that is making life better for infectious diseases.† Rising Sea Levels It has been proved that water expands on heating, and so sea levels are also expected to rise due to the global warming and greenhouse effect and the possible climatic change. Thus rising sea levels will also because of the polar caps as they are melting because of the global warming. This rising sea level is already having a negative effect on many small islands. The World Watch Institute has reported that the Earth’s ice cover is melting in more places and at higher rates. (March 6, 2000). This can also have an impact on many coastlines and small countries, and a large population of people of humanity lives near the coasts or by major rivers. (http://www.globalissues.org/article/233/climate-change-and-global-warming-) The relationship of Green house and Ozone Depletion The ozone layer is very important as it protects the environment from the harmful rays of the sunlight. Thus ozone shield is important as it forms a barrier and protects plant and animal life on land from the suns ultraviolet rays, which may cause skin cancer, cataracts, and damage to the immune system. Ozone layer depletion can also alter the DNA living creature on the earth. Thus ozone layer is very important for the life in the earth. Shindell, et. al. wrote inNature, that Greenhouse gases warm the Earths surface but cool the stratosphere radiative, and therefore affect ozone depletion. Moreover by the end of 2019, Shindell, et al. expects that the ozone layer may reduce by two-thirds in the Arctic poles. Not only this, the severity and duration of the ozone hole in the Antarctic are also likely to increase, this may be because of greenhouse-gas-induced stratospheric cooling over the coming decades. As reported by NASA researchers and also by European, Japanese, and Canadian scientists, there is a connection between global warming, a cooling stratosphere, and depletion of stratospheric ozone. The report also says that the ozone layer is having a stabilizing effect on the Antarctic poles, whereas ozone levels in the Arctic circle are still falling. Conclusion: As per (Bruinsma 2011), there has to be an increase in total global food production by at least 70 to 100 percent by the end of the year 2050. It’s only then we can adequately feed a global population of nine billion people at that time. It has been already seen that China and India, the worlds most populated nations, and both the country has more than 1 billion inhabitants; each has sustained once a year gross domestic product (GDP) growth rate over 10 years ago that is among the worlds highest 9 percent for China and 7 percent for India, moreover it has been estimated that by the year 2025, Indias total population will be equal to China’s population, thus making India the worlds most populated country. In the year 1961, the information available on the annual market supply for almost all countries in world and production of agricultural commodities. In the western world, agriculture, transport and protect food in the technological development at the end of the 19th ce ntury led to the expansion of the food industry and food preparation shifted from households to industry, so stimulating the nutrition transition. Worldwide it has been noted that water shortage reflects the per capita decline and also in irrigation for the production of food. Also because of the population increase and also increased pollution the Ozone layer is getting depleted and is causing global warming and which will be the major cause of plant and human disease. So it is needed that the pollution should be as low as possible. It is also needed in future that the global food production should be increased by adopting new and innovative and mechanized method for production and cultivation of the crop.

Delivering Moral Messages in Where Are You Going, Where Have You Been a

Delivering Moral Messages in Where Are You Going, Where Have You Been and A Good Man is Hard to Find School shootings, bombings, rape, and murder are words that are commonly seen in newspaper headlines and heard on the morning news. To most people these acts seem like senseless violence. However, writers like Joyce Carol Oates and Flannery O’Connor use these same violent images to deliver a powerful moral message. Their stories â€Å"Where Are You Going, Where Have You Been?† and â€Å"A Good Man is Hard to Find† are very comparable in the lessons that they teach. Joyce Carol Oates’s â€Å"Where Are You Going, Where Have You Been† begins with the introduction of it’s main character, Connie, a fifteen year- old girl. Oates makes Connie’s vanity quiet well know by telling the reader that Connie has the â€Å"habit of craning her neck to glance into mirrors†. Indeed, it is this vanity and Connie’s innocence that places her right in the path of Arnold Friend. Arnold will confirm this by telling Connie that there is nothing else for â€Å"a pretty girl like you but to be sweet and give in.† In fact, critics generally interpret this story as Connie’s initiation into evil. What’s in a name? If you’re talking about one of Joyce Carol Oates’s characters, a name can say a lot. Arnold Friend’s name can be interpreted as â€Å"aren’t no friend† or â€Å"A. Friend† (Johnson 150). Either way his is a demonic figure that represents the death of Connie’s spirit. In fact, Arnold Friend is based on a serial killer know as â€Å"The Pied Piper of Tucson.† As Oates reports, this â€Å"tabloid psychopath† specialized in â€Å"the seduction and occasional murder of teenage girls† (Wesley). The Pied Piper was in his thirties; yet, he managed to counterfeit teenage dress, talk, and behavior. He also stuffed rags into his leather boots to give him height. These elements of the Pied Piper’s behavior are very obvious in Oates’s portrayal of Arnold Friend (Johnson 148). Joyce Carol Oates dedicated â€Å"Where Are You Going, Where Have You Been† to Bob Dylan. His song â€Å"It’s All Over Now, Baby Blue† was her inspiration. The many lines from Dylan’s song obviously influenced the story (see appendix A). The vagabond who’s rapping at your door Is standing in clothes that you once wore. However, the mood and tone of the story also reveal more subtle connections (Davidson). â€Å"Where Are You Going, Where Have You Been† has ... ... and The Misfit play similar demonic roles and serve as a reminder that evil can come in many forms. They both violently lead their victims to make religious epiphanies. The price paid for their spiritual rebirth is an immediate death. Both Flannery O’Connor and Joyce Carol Oates have been criticized for their violent writings. However, the acts portrayed in their stories aren’t senseless. They are meant to show the purification of the involved characters. Also, they serve as a catharsis or reassurance of faith for the reader. Works Cited Davidson, Rob.

Class or Mass Case Analysis Essay

Class- or Mass?: Case QuestionsNeptune Gourmet is facing the problem of an inventory pileup. The company needs a way to sell the excess inventory. At the same time many new ships were purchased and expected to operate, which increases supply. Rita Sanchez proposes a cut in prices of the product by fifty percent. This price cut poses a problem due to the fact the Neptune Seafood is a premium product and usually sells for a higher price than the competition. In order to maintain the premium product image Sanchez proposes starting a mass market brand to decrease inventory. There are many variables but some of the bigger ones include; creating the separate brand at all and whether or not the new brand would be associated or separate from the current Neptune brand. Some executives agree with Sanchez while others take the side of Jim Hargrove in disagreement of the proposal. The dilemma is whether the company should start a new brand and price it at fifty percent of the Neptune Gold brand in order to increase sales and decrease inventory. The executives have many conflicting opinions about the effects on the image of the Neptune brand if this method of inventory reduction is carried out. The goal of research for Neptune is to determine the effects on the consumer’s views if a new brand is implemented. How well would a new brand perform entering the current market? Is there already a popular brand on the market that has the low cost segment secured? Neptune should look into what their competition would be in an almost new market. This new brand would likely be seen as lower quality due to the price. With the Neptune name associated the quality image would be strengthened for the lower price product. As mentioned in the case would the grocers fail to stock the product for fear of competition with the stores own private label product?Should the brand be associated with the current Neptune Gold brand or would that hurt the current premium product image. If the name of the new less expensive brand was Neptune Silver, as suggested, but had the quality of Neptune Gold would customers be lost to the lower priced product. Would the lower priced product increase the market size into a lower income bracket? Again, what is the market currently like for low priced seafood? One of the important strengths of Neptune is the fact that all of their products have the Association of Seafood Processors and  Distributors â€Å"Gold Seal of Approval†. If this new brand didn’t have that seal would that also affect the company image?If this is a feasible investment what effects would flooding the market with a low priced product cause. Will other companies with inventory pile-ups respond and cause a price war? The other companies in the market are bound to do something in response to the low prices. If Neptune chooses to do nothing with the stockpiled inventory another company is likely to sell at a very low price to decrease inventory first. Is it a good idea to be a first mover and capture the low priced market early?Also, would targeting South and Central America be a favorable option? In a country where the lower price by U.S. standards wouldn’t seem quite as low, Neptune could keep its premium status while still decreasing inventory. In addition, expanding into other countries could prove to be a profitable venture. At the same time hopefully the expansion could increase demand and decrease the surplus of inventor y. Overall would the venture be profitable? More precisely is the infrastructure in South and Central America suited for distribution or would this cost reduce the feasibility of the investment. A market analysis would be a good starting approach to researching this plan of action. The first step is to define your target market. You need to know exactly what the consumers are like, and how large the market is for the lower price product. Here you could find out who is going to buy the product and how much demand there will be. Projections could be made on the affect to the market and what policies are in place that could decrease profitability. In solving the marketability issue this method along with a SWOT analysis would be very useful. With the problem Neptune is facing in regards to product image, I would use an exploratory approach to learning about the consumer. I would host focus groups to try and determine how the inexpensive brand is associated to the Neptune Gold brand. This would help determine if the brand should be associated closely with Neptune Gold or held distant from the core product. Should Neptune expand into Southern and Central America? Exploratory in-depth interviews would be a quality option for determining if the market would  accept the product or not. You could look for some secondary information on how other similarly priced seafood products performed in that region. The individual would be the best for a focus group in determining the product image dilemma. It could be determined if different financial groups would react differently to the new brand. For example; would the less expensive brand be substituted by the middle class individuals to save money?With a market analysis most of the information would be secondary. The research would involve finding the right data to give the best idea of how well a new product would do in the market. It’s possible that other institutions could be approached in search of information. This would give quality information on where and what would work best for Neptune. With the foreign market problem the research should be done on the retailers and suppliers for the most effective information. These people could tell you pricing and sales information of products currently sold in South and Central America. Also, culture in other countries has to be considered. Most of what you would need to know to enter a new market, the suppliers and retailers could convey through interviews.

Dog Whistle Politics Of The 1960s - 2333 Words

Jacob Garbison Professor Sean Trundle History 355 4 December 2014 Dog Whistle Politics of the 1960s On July 2, after signing the 1964 Civil Rights Act, President Lyndon B. Johnson reportedly said to his staff, â€Å"I think we just gave the South to the Republicans for your lifetime and mine.† (Perlstein 365) He was wrong. Although he never lived to see it, Jimmy Carter won a Democratic South in 1976 - but it was for the last time. Nonetheless, the party which had dominated the South for almost a century had put it up for grabs with the stroke of a pen. The impact of racism on presidential politics during the ‘60s is difficult to overstate. Race and racially coded language in particular played a profound role in the GOPs success at winning†¦show more content†¦Here, Wallace did something new. Gone were the overt references to white supremacy, segregation, or even race. Instead, he positioned himself as a defender of the constitution against tyrannical government overreach: â€Å"I stand here today, as Governor of this sovereign State, and refuse to willingly submit to illegal usurpation of power by the Central Government.† [1] Wallace went on, giving voice to the politics of the South in language that was palpable, even agreeable, to the North. The dramatic â€Å"Stand in the Door† was all for show of course. Wallace stood aside, allowing three black students to register for classes later that day, but the effects of the speech would have wide repercussions. Wallace received nearly 100,000 telegrams in response to his speech from all across the country, an almost unheard of number for a lowly Southern governor. More shocking still was that nearly all of them, about 95%, were praising his bravery. (Lopez, 15) â€Å"They all hate black people, all of them.† Wallace reportedly exclaimed, â€Å"They’re all afraid, all of them Great God! That’s it! They’re all Southern. The whole US is Southern!† (Lopez, 15) Wallace had discovered the dog whistle, a way to communicate racial animosity without using explicit racism. This is a distinctly modern expression of racism which, as Ian Haney Lopez says, â€Å"[stimulates] the intended audience without overtly

Essay on Opportunity Cost And The Free Market - 1736 Words

OPPORTUNITY COST THE FREE MARKET Scarcity is one of the most basic and crucial points to understand in microeconomics.1Scarcity means that we cannot have all the needs and wants to satisfy our desires. Scarcity can be applied to almost anything. Due to the scarcity of products we must make a choice of what we want. We must choose whether to do one thing or another by what we value to be most important to us. This, therefore, leads to us opportunity cost. Usually when one has to make a decision over what to do, buy, or build, it is narrowed down to two things. We might choose what satisfies our desires, what is more economical, or what is needed more. The choice that we do not take is our opportunity cost, the choice that we value†¦show more content†¦As shown on the diagram below if the government only builds schools then they are at point A, which means they are not building libraries, therefore not allocating resources. If they concentrate only on building libraries, and not schools, then they are at po int E. In order to build both they would need to place themselves at points B, C, and D. At point B there is a bigger production of schools and a small production of libraries. At point D, there is a larger production of libraries and a smaller production of schools. The most effective point would be C because they would concentrate all their efforts on both schools and libraries and therefore have the best allocation of resources and have no opportunity cost. All these factors combined are essential to making better economical decisions for any society. The production possibility curve helps deicide more efficient ways to distribute resources. Businesses and government have to find all the different possibilities, study them, and make the best decision on what is best to produce and what would bring in more profit. Opportunity cost can also help us understand what products a consumer might choose to buy and the best price for the product. This can also help companies decide on bett er ways to proceed with sales. The free market is a well-advanced state of economy in a society.
