What are the implications of climate change to development? Climate change is one of the most fundamental challenges ever to confront humanity. Its implication on development is all-encompassing, affecting food security, health and safety, infrastructure, international trade, and the overall economy of a country. It also affects development policies in terms of tradeoffs, short-term actions versus long-term benefits, and individual choices versus global consequences. According to the…

Introduction For the past three years—due to the global surplus of crude oil production resulting in lower crude prices—oil & gas industry has become a dynamic marketplace and the constant drive for survival and excellence has put the companies on toes to modify their strategies for the next round of competition. Consequently, cost optimization is the near-term strategy in the whole oil & gas industry, and Qatar Petroleum (QP) is no exception. As part of cost optimization, QP examined all the…

1. INTRODUCTION Graphene is the most required engineering material in the twenty first century, largely due to its exceptional mechanical, thermal and electrical properties. For Example monolayer of graphene sheet has Young’s modulus of about 1 TPa [Ref], shear modulus of 280 GPa [Ref], fracture strength of 130 GPa [Ref], thermal conductivity of 5000 W/mK [Ref], longitudinal sound velocity of 20Km/s [Ref], melting temperature of 4900 K [Ref] and also it has high electron mobility of 250,000…

TOP 10 BEST WINTER FACE MASK Winter brings along dryness, redness and so much more problems that the skin has to bear all throughout the season. Therefore it becomes absolutely imperative that one takes proper care of the body and specially the face which happens to have a very sensitive skin during the winter months. Winter face masks serves an important purpose of keeping the skin from drying out. However not all face masks are meant for winter and most do not work properly and creates rashes…

In the era that we live in today, mankind has become dependent on fossil fuel just as much as water and oxygen. We continue to depend on fossil fuel for every aspect of our daily lives while at the same time fighting against mother nature. As we continue this ignorant battle against nature who knows what the future will look like. Will we still have fossil fuel? Will we still have water? In Octavia Butlers, “Parable of the Sower”, she creates a world full of chaos and catastrophe yet a world…

The talk about using nuclear power as a new energy source has been a big discussion amongst many. Many shared their views on nuclear energy being our new soce of power. Negative and positive feedback from many articles, professors, funders, and ordinary people have made it hard to come to an agreement on whether or not to move forward with making nuclear power the new source of energy. Events such as the one in Fukushima and the radiation spill in Pennsylvania have caused many to fear and fight…

Water used to be the most common substance that could be found anywhere in the world, but as of lately that hasn't been the case. It is been getting harder and harder to fulfill our need of water. In the excerpt “Water Controversies Boil Over” written by Mat Weiser, published in April 26, 2009 he talks about how people are starting to fight over water and how 46 nations risk violent conflicts over water. Weiser explains how the United Nations stated that in the future there won't be conflicts…

on of which was the creation of gas. Gas is a result of a process which extracts lubricating and fuel oil were removed from crude oil. France, Germany, and Austria, early in the nineteenth century, began developing internal combustion engines. Nicholaus August Otto, a German, created a gas-powered four stroke engine in the mid 1860’s. One of his employees later perfected an engine which could be used in automobiles. Charles and Frank Duryea built the first the gas-driven vehicle in 1893 three…

Recently, the New York Times published an article that left people both stunned and amused and unlike some of their articles it dealt with...trash. Apparently, more than one hundred and eleven million dollars have been spent and invested in the recycling industry. Now why would someone spend one hundred and eleven million dollars on the recycling industry one may ask, the answer is simple... economy benefits. Recycling can lower capital cost, make us use 80 to 90 percent less energy, lower our…

Many climate scientists believe that human beings are the cause of climate change 1. Impacts of climate change are involved in natural environment, human health, etc 3. Examples of impacts of climate change are higher temperature, increase in sea level, wildlife at risk, more drought and floods, bushfires, decrease in economy, higher chances of getting heart diseases, etc. Collin Kelley who is a climatologist stated that conflicts occur is not only because of climate change but it is also due to…
