Prediction of Corrosion Rate and Its Affecting Factors on Surface Casing Abstract Corrosion is a physicochemical phenomenon affected by multiple factors. The effect of these factors on corrosion depends on their concentrations and interactions with each other. It is not possible to establish a direct one to one relationship between the values of a single […]
I. ABSTRACT (ENGLISH) The experimental determination of the yield of pyrethrins from the Chrysanthemum cinerariaefolium flower is usually carried out with Chromatographic Techniques. A lot of methods about this have been reported over the years [Z-M. ChertY.H. Wang (1996)]. These include HPLC [13 -22], GC [22-26] and SFC [B. Wenclawiak, A. Otterbach (2000) methods. Because […]

Get startedChapitre I: la théorie économique I.1.La partie théorique: C’est bien connu en économie comme en philosophie, tout remonte toujours à Aristote. Dans le cas du rapport entre les économistes et l’écologie, cette généalogie parait cependant encore plus forcée qu’à l’accoutumée. Pour deux raisons majeurs. La question du rapport entre l’activité économique et les ressources naturelles […]
Chapter- 4 ABIOTIC ENVIRONMENTAL VARIABLES OF MORAINIC AND ALPINE ECOSYSTEMS Global warming/ enhanced greenhouse effect and the loss of biodiversity are the major environmental issues around the world. The greatest part of the world’s population lives in the tropical regions. Mountainous regions in many cases provide favourable conditions for water supply due to orographically enhanced […]
III – Pathologies environnementales, métaboliques et tumorales Dans ce chapitre, il sera question d’examiner les pathologies non infectieuses dont souffrent les poissons d’ornements. Ainsi nous verrons les pathologies environnementales, métaboliques, alimentaires, tumorales et génétiques. 1- Pathologies environnementales Dans le milieu naturel, la composition chimique du milieu hydrique se constitue au fur et à mesure du […]

INTRODUCTION Global warming is defined as temperature increase world wide due to green house gases emission and cause deletion to ozone layer [1]. It mainly occurred due to the burning of fuel, Green house gases include chloro- fluorocarbon (CFC), carbon dioxide, nitrous dioxide, methane, sulphur dioxide. Carbon dioxide, sulphur dioxides are the major gases that […]
Abstract Different environmental conditions contribute to the limitations of plant growth. Salts are common and a natural constituent of all soils. Normally, salts are present in low amounts in top soil and plant growth is not affected. However, accumulation of salts, through natural means or man’s activities, can cause plant growth problems and result in […]
Ecological Footprint analysis has been conducted at a various levels such as nation, region, sector, company and product. There are various methodologies followed to analyze the ecological footprint depending on many factors. This part of the report addresses the ecological footprint methods. 4. Fundamentals Prior to conducting ecological footprint analysis, there are certain fundamentals which […]
Global Warming Thesis CHAPTER 1 INTRODUCTION Climate change in today’s age is representing the latest in a series of environmental drivers of human conflict that have been identified in recent decades, following others that include drought, desertification, land degradation, failing water supplies, deforestation, fisheries depletion, and even ozone depletion. By the 1990s, climate modeling had […]
Issue 8: Is Global Warming Skepticism Just Smoke and Mirrors? Ginger Powers SCI 207 Dependence of Man on the Environment Norman Stradleigh July 25, 2010 What exactly is global warming? Do you know the answer, maybe you do, however, taking a pretty good educated guess I would tend to think that most people think they […]
Global Warming also called climate change is the increase in higher temperature of the Earth. Also, because the amount of the human generated greenhouse gases absorbing heat from the sun and then sustaining it within the atmosphere. The causes of Global Warming is a very serious environmental issue, with excess release of Carbon Dioxide into […]
Introduction Cryptocurrencies have progressed in our society and have come a long way as a trading alternative. Digital currencies like Bitcoin or Ether have made themselves the most popular growing unit value and proved to be the most successful and legitimate transaction. Although cryptocurrencies have massive and multiple benefits, it does not exist without its […]
Introduction “Earth’s 2016 surface temperatures were the warmest since modern recordkeeping began in 1880” (NASA, NOAA Data…) The atmospheric co2 levels of Earth have always increased and decreased over a period of 650,000 years. However, as of 1950, carbon dioxide levels have increased to 400 million, which is significant when compared to the highest of […]
As the population is growing exponentially, The FAO estimates that global demand for food will jump by half from 2013 to 2050. “With 3.4 billion more mouths to feed and the growing desire of the middle class for meat and dairy in developing countries, global demand for food could increase by between 59 and 98 […]
Fossil fuels give off carbon dioxide when used as a fuel in vehicles, industries, etc. Deforestation to make space for houses and provide wood for furniture and paper products results in an overall reduction in the amount of trees. Plants absorb carbon dioxide for photosynthesis and in their respiration process leaves oxygen, which animals and […]
Causes of Global Warming Climate has changed rapidly for 50 years. Recently, we can feel the temperature is changing rapidly and environmental experts also agree with this. In the world, a lot of countries are greatly affected by the warming of the earth especially the Maldives. The island’s highest location is only about 2.5 meters […]
I’m sure that at some point through the course of your life you have heard the term “air pollution.” What is air pollution? Why is it important? Am I causing air pollution myself? These all might be questions you ask yourself. Air pollution consists invasive gases or particles that is harmful and introduced to a […]
In the present day, contamination is a word we often hear, we become so used to hearing it that we often ignore it. However, it is, and air pollution is a very dangerous form of pollution that affects all of us. Containing high levels of carbon dioxide, carbon monoxide, lead, chlorofluorocarbons, and many more. It […]
Since the dawn of humanity, energy has been the driving force towards survival, continuation of society, as well as development. All sectors of modern economy are highly dependent on energy sources. The constantly expanding human needs require every day a greater amount of energy supplies. Nutritional needs, medicine, transportation, manufacture and construction are just a […]
The Future of Nuclear Energy Abstract Climate change is a threat to the entire planet. The increase in global temperature is significantly altering our planet’s climate, resulting in more extreme and unpredictable weather. Greenhouses gases, such as carbon dioxide, trap heat in the atmosphere and regulate our climate. These gases exist naturally, but humans add […]
