The Nitrogen Cycle - Statistics Project Example As a result, the salinity gradient was different along Kinvara Bay in time point 1 in comparison to time point 2. The periplasmic reductase gene Napa and the membrane-bound narG were presented in the sediments where Napa had a high affinity for nitrate in comparison to narG. Moreover, it was identified the presented bacteria in the bay were rather similar to those in Colne Estuary sediments, United Kingdom, back in 2007. (Smith et al., 2007). In general, the presented bacteria were from gamma proteobacteria, which is strongly associated with Napa reductase gene. Overall, another extensive study is needed to fully understand the denitrifiers Napa and narG community and structure in the environment. Further, quantitative polymerase chain reaction is necessary to quantify gene copy numbers of these two genes (napA and narG) present in the environment. Sediments from time point 1 and 2 of all the three sites were heated in the oven overnight to ignite the carbon. Subsequently, the sample s were weighed to calculate the total organic carbon. Carbon source was considered as being crucial in the denitrification process.  Water salinity was measured by a Refractometer. This is quite an easy type of measurement to account for salinity.  Measuring the sediment salinity was accomplished through different steps.   Primarily, distilled H2O was added to all sediments from the three sites from time point 1 and 2. The sediments were centrifuged and this allowed the salt in the sediments to be dissolved in the water.   The dissolved salt was then filtered and evaporated in the oven overnight, weighed, and then calculated. The sediments salinity was represented the different gradients through the three sites,   from both time points 1 and 2.

Persuasive speech; How violent video game affect children Essay

Persuasive speech; How violent video game affect children - Essay Example The increasing trend of using technology and gadgets is reducing the degree of outdoor activities for children. This results in increased durations of indoor activities that mainly constitute of watching TV and playing video games. According to Reinberg, US kids spend around 8 hours watching TV and playing video games every day. The modern video games have alarming levels of aggression and violence in them since they are mainly based on warfare or combat themes. Anderson stated that many scenario based games revolve around the killing of innocent characters with guns, knives, fighting etc. Exposure to such level of violence and aggression for elongated durations affects the players on a short term, as well as a long term basis. Kooijmans stated that violent games cause an increase in destructive cognitions and negative arousals. He also stated that violent video games induce hostile attitudes and beliefs among the users on a long term basis. The high quality of graphics and animation make the scenarios look genuine and give the perception of a real life. Anderson stated that experience of such real life violent situations makes the individuals insensitive to other people’s suffering and pains since they view such details on a daily basis in the form of animated characters. Benedetti pointed out that the increase of violence in video games is having another severe effect on the new generation; shootouts in schools. There have been numerous instances where students have opened fire at their fellow students and caused massacres. Examples of such incidents include Colorado shootout in 1999, Viginia Tech School shootout in 2007 etc. Layton stated that the shooters in the Colorado shootout were excessive players of ‘Doom’, ‘Mortal Kombat’ and ‘Wolf 3D’. These games were considered to be popular and common violent games of that era. Layton also

Thus, media, especially the role of television in defining the cultures of Arab world and American society is important facet in the contemporary times.

Adam Smith & John Maynard Keynes Essay Example | Topics and Well Written Essays - 2000 words - 1

Adam Smith & John Maynard Keynes - Essay Example Smith sought to convince people that "the wealth of a nation would be promoted with vastly greater effectiveness by the ‘obvious and simple system of natural liberty’ than by national planning of the mercantilist sort" (Mitchell 48). As for the implementation of Smith’s ideas, his influence on today’s economy is probably greater than it was on his contemporaries or those who lived immediately after his works were published. â€Å"An Inquiry into the Nature and Causes of the Wealth of Nations† (or more commonly â€Å"The Wealth of Nations†) by Adam Smith, published in 1776 is widely considered to be the first modern work in the field of economics. Up until â€Å"The Wealth of Nations† it was generally accepted that in any economic transaction one side always "won". In other words, either the buyer or seller got to "put one over" on his "opponent" — one went home happy, the other went home and eventually got angry at himself for being a dupe. Smith rejected this notion, however, and stated that "a voluntary, informed transaction always benefits both parties": when the buyer gives something of value to the seller in exchange for something else of value, both parties "win". This is because the buyer values what the seller is selling more than what he is giving to the seller in exchange for it. And, for his part, the seller is all too happy to part with what he is selling for the buyers property, because he values that more. In short, each party gets something he wants more in exchange for something he wants less — they both benefit. This book is a clearly written account of political economy at the dawn of the Industrial Revolution. Mercantilism was the ruling economic principle then. â€Å"The Wealth of Nations† attacks two fundamental principles of mercantilism: the idea that protectionist tariffs serve the economic interests of a nation; the idea that large reserves of gold bullion or other heavy metals are necessary for a countrys economic success (Smith

The war in syria and its consequences on lebanon Research Paper - 1

The war in syria and its consequences on lebanon - Research Paper Example The armed opposition is an alliance of various groups, which were formed during the conflict to protect the civilian protestors and face off the government forces. This civil conflict has however progressed to become a regional problem, affecting other countries that have remained neutral to the domestic issues that are facing the country. As opposed to being an effort to eliminate Assad leadership in Syria, the conflict has graduated into a sectarian conflict, leading to emergence of Alawite government forces and pro-government militias made up of members of the Shia tribe (White 16). The opposition is dominated by members of the Sunni tribe, a situation that has led to an increase in foreign interference in the course of the war. For example, in 2013, the Hezbollah terrorist group joined the civil war to fight alongside government forces and defeat the Sunni dominated opposition forces. As the war progresses, its impacts have been felt beyond the borders of Syria, spilling to neighboring countries, which are currently, faced with major insecurity challenges. Lebanon, a country with the longest borderline with Syria is considered as one of the few neighboring countries that have significantly been affected by the civil war. As a result, the Syrian conflict has had significant security challenges to Lebanon as the fight has virtually spilt into the country. This has further affected the economy and the healthcare sector in the country as major basic and social amenities are suspended as has been witnessed in the war torn Syria (Dahi 12). Despite the ravaging ramification of the Syrian internal conflict, scholars have made little effort to bring to the fore its effects to peace and stability in neighboring countries. Efforts have concentrated on how the war has affected the social and economic stability of Syria and how the Assad and opposition

Water and Sustainability Essay Example | Topics and Well Written Essays - 1500 words

Water and Sustainability - Essay Example In his analysis of the concept of property, Professor Macpherson is concerned with the profound task of re-evaluating the analytical definition of property by returning it to its historical roots (Macpherson, 1 – 12). Such an approach encourages a new understanding about public or communal property matters that have been of concern to communities and governments within the relatively recent past, challenging human rationality and human control. The problems associated with an equitable distribution of water, which is becoming an increasingly scarce resource of vital importance to all humanity, has the capacity for enlarging perception and challenging the mind in its quest for equitable ways of governance and modes of thinking. This is especially true for the Western United States of America in which most of the land lying west of the 100th meridian of longitude receives less than 20 inches of rain annually (MSN Encarta, â€Å"Water Policy in the American West†). The notion of property presented by Professor Macpherson stipulates that the use of the term property to represent things is a misusage (Harris, Chapter 9). In effect, the concept of property has logical and historical dimensions. The logical dimension associated with the concept of property stipulates that property refers to the right to the use of or to benefit from things. Thus, private property rights extend to exclude others from the use of private property. However, property is not always private in nature and the concept of ‘common property’ prevails whenever resources have been set aside for common use. Thus, the notion of common property can give rise to ‘enforceable claims’ not to be excluded from the use of resources. For common property, it is important to understand property rights within the context of the rights of others people, sometimes all people. Thus, common property must be considered within the context of Hohfeldian relations and priv ileges for property
