Our world is becoming more uncertain, disasters are increasing in frequency and severity with devastated consequences for people. Natural disasters are inevitable though human activity has a gradual effect on occurrence of such disasters, but there are many elements that are beyond human control or influence. Today the entire humanity confront frequent and grew some disasters. Disaster risk is therefore is increasingly a global concern. There are many factors affecting the intensity of these…

Carbon Democracy: Political Power in the Age of Oil Timothy Mitchell (London and New York: Verso, 2012) Timothy Mitchell, in his book ‘Carbon Democracy’, ventures into a very broad and interesting area of democratic struggles as reflected largely in the transitioning from coal to oil as a primary source of fuel for industries in essentially already industrialized countries. In other words, the author primarily argues that the production, acquisition of energy and the emergence of democratic…

Acid Mine Drainage (AMD) and Control Options AMD comes from the oxidation of sulphide minerals. It has the negative impact on the environment. Since it could affect the surface water, ground water quality and land used. This condition due to the low pH contains by the water (could reach up to 2), sulphate content (SO4), and metals content (Fe, Zn, Cu, Ni, As, Cd). The principles for AMD formation should be understood to be able to manage the water. i. Waste containing reactive sulphide (S2-,…

Thesis Statement: The world's population growth has caused a destruction of the environment. I. Agriculture may look common and environmental friendly but as the amount of farm increased with the population, we had actually damaged the environment. A. Farming had caused soil erosion and degradation. 1. As we build more farm for planting usage, many forest had been damaged.It may further lead to soil erosion. 2. Pesticide and fertilizer used destroy the soil’s natural properties, not to mention…

Until recently it was believed that the earth had only experienced 4 to 5 glacial periods, all of which occurred in the past 2 million years. (Louis Agassiz, 1837) However, globally conducted research has revealed that countless glacial advances have appeared over 200 million years ago, thus broadening our insight of the history of the earth system by 100 times. These astonishing advances have witnessed the introduction of a new sub-discipline—palaeoclimatology, which specialises in the study of…

OPTIMAL SIMULATION OF CO2 WAG USING COMBINATION INJECTION AND PRODUCTION SCHEMES TO ESTABLISH IMPORVED EOR PROCESS INTRODUCTION: It’s been almost 40 years that CO2 flooding is used as an Enhanced Oil Recovery technique by the exploration and production industry. The technique was first used in Canada in 1957 as a pilot test and got commercialized in the early 1970s. The usage of CO2 as a displacing fluid to further reduce the residual oil saturation after the water floods has been a trend which…

Manhattan Project and The Analysis of Atomic Explosions History is defined as some event that has happened in the past with having a impact in some area on Earth. Without history people would not be able to learn from their past mistakes and continue on with life. This learning from our mistakes can change what people do or how people do different things. In history we have learned that war can cause many new jobs for people, but with war so many lives are lost. We have learned from many…

One of the parameters that determines water quality is pH. It is defined as the negative logarithm of the hydrogen ion and is intended to be a measurement of the balance of acids and bases. Temperature affects pH. In pure water, a decrease in pH of 0.45 occurs when temperature is increased by 25°C [11]. There are several methods for measuring pH. The most common is the use of a glass electrode sensible to it, a reference electrode and a measurement device. Another method is the use of…

becomes more than the oxygen been diffused then waterlogged soils can become anoxic. The changes that pertain to changes in concentration of carbon dioxide and other trace gases takes place in the minor pores and bacteria are found in the smaller pores. The roots of many plants that grow in aerated soils also take in oxygen and exhale carbon dioxide. This represents how the concentration of these gases can be influenced by the root system and its…

The first HEPA filter was developed in 1940 through the military forces for it to be used in the Manhattan Project. The primary concern then was to be safe from the nuclear material that was freely floating in the air. In the modern times HEPA air purifiers are used all over the world to pollen, dust, mould, certain forms of bacteria and other particles that are air-borne. The HEPA Air purifier by far has been the best type useable since it is very efficient. The most advantageous aspect of this…
