Introduction: Photosynthesis is one of the most fundamental processes that take place in plants and some other organisms. Photosynthesis converts solar energy into chemical energy of a carbohydrate (Mader & Windelspecht, 2013).The whole process takes place in the chloroplasts of green plant cells containing the pigment chlorophyll. Chlorophyll is one of the most important molecules in existence as all energy capture starts from there (Mader, 2010). If none of this pigment is in existence, plants

Fossil oil accounts for more than half of all oil used in the world today. It is true oil is non-renewable and most nationsare heavily dependent on fossil sources for energy, these are excellent reasons and incentives for researching, investing and developing renewable energy sources.Biomass for energy,in contrast to fossil fuels provides significant environmental advantages. Plant needed to generate biomass feedstock

RESEARCH BACKGROUND Globally, waste generation is on the rise with significant increases being recorded in developing countries, such as Jamaica. In Jamaica the average per capita waste generation increased from 0.74 kg/day in 2007 to 0.86 kg/day in 2009, ESSJ (2010), and is expected to continue in light of the government’s plans to achieve developed country status by 2030. The higher the per capita GDP of a country, the higher the quantity of waste produced, Stanners and Bordeau, (1995); European

Dioxins are primarily by-products or residues from thermal industrial processes (combustion) that involve chlorine, but they can also occur during natural phenomena such as volcanic eruptions or forest fires. They are undesirable byproducts in a large number of manufacturing processes, such as melting, chlorine bleaching of pulp, and the production of certain herbicides and pesticides. In terms of emissions, it is considered that most of the dioxin released into the environment comes from uncontrolled

Experimental Optimization of LHP with Flat Plate Evaporator Scientific background All electronic devices and circuits generate excess heat and if the operating temperature exceeds the certain limit it greatly effects the performance of the device and consumer safety, thus require thermal management to improve reliability and prevent premature failure. With the continuous increase in functionality and performance of electronics chips, along with the advancement in technology for large-scale integration

URANIUM MINING 1. INTRODUCTION Mining industry for the past decades has been the backbone of sustainable economic development many first world country and 90% of developing countries. However, despite their contribution they are also associated with social factors that are detrimental to the environment. Uranium mining are associated with significant environmental impact, and they are regarded as one of the most damaging form of mining due to the fact that uranium mining are associated with emission

The essay will elaborate more on Sea level rise that occurred due to climate change. Sea level rise is a serious global threat that continued to grow due to greenhouse gas emissions and associated with the global warming. In context, Solomon Islands like most of the South Pacific countries had been ignorant about the issue of the increased concentration of greenhouse gases and its effects until recently. And as such, comprehensive understanding of sea level rise and climate change it real associated

Adaptation Plans Adaptation is the act of adapting to the effects of climate change which is important in dealing with the impacts of climate change that are already happening as well as preparing for future impacts (UNFCCC, 2008). Adaptation planning enables countries to generate and implement national adaptation plans so as to identify medium and long term adaptation needs. Adaptation planning is a continuous process; that is guided by the country. This process is participatory, transparent

Bone structure Spongy bone also knowns as cancellous contain red and yeallow bone marrow. Red bone marrow produces roughly 200 million of red blood cells (RBC) per a day. Yellow bone marrow contains primary fat cells. This can be transformed into red bone marrow to provide RBC if needed (Ivy Rose Holistic,n.d). The sponge is light and have low density which balance the heavier parts of bone. Sponge tend to form a long line of stress which gives strength and flexibility in that area (Biology dictionary

global economy and world population in the near future will lead to an increased demand for energy [1], resulting in an even further increase in the atmospheric CO2 concentration [2]. In recent years, the amount of CO2 liberated by the utilization of fossil fuels has been over 30 gigatonnes. Global GHG emissions have doubled since the early 1970s, and the emissions would double again by 2050 without appropriate and effective emission abatement. Although international attempts have been made to reduce
