Oil is a by product of crude oil, it is a non renewable resource that is refined in to many other different energy products such as: diesel, gasoline, heating oil, jet fuel etc. Oil is extracted from crude oil through a process called fractional distillation; crude oil is heated with oxygen, which results in different chains being pulled out by their vaporization temperatures, due to this reaction. Each different chain length has a different property that determines what product it makes; motor...
Abstract Among the common mineral rock-forming minerals, perhaps no major group in as poorly understood as the amphibole group. This is because double-chain silicates are very complicated with regard to crystal structure, chemical variation and natural occurrence. Consequently, although many amphibole species have been distinguished, mostly on a chemical basis, it is difficult to relate the geologic occurrence to physical and chemical principal. Introduction Amphibole is defines as an important...
Global warming is the result of the greenhouse effect created by certain gases, such as carbon dioxide and methane in the atmosphere. The increase of these gases is caused by industrialization, especially by the use of fossil fuels such as coal and oil. These gases act like the glass in a greenhouse: They let sunlight in and keep the heat from escaping. There are many sources stating different things, some agree with these statements and others strongly oppose it. There is considerable evidence...
Pharmaceutical formulation is the process in which different chemical substances including the active drug are combined to produce a final medicinal product. Formulation studies involve developing a preparation of the drug which is stable and acceptable to the patient for use. Formulation studies are consider factors such as particle size, polymorphism, pH, and solubility, as all of these can influence bioavailability and the activity of a drug. The drug must be combined with...
Fruits and vegetables play an essential role in human nutrition. Apart from providing flavor and variety to human diet, they serve as important sources of vitamins and minerals which will prevent diseases and promoting health. Most fruits and vegetables contain more water and therefore highly perishable. And water loss and decay account for most of their post-harvest losses and short storage life. But, serious losses will arise in the availability of the essential nutrients, vitamins and...

The last remaining of the Carrum Carrum Swamp, Edithvale Wetland, is located in the surburb of Edithvale, Aspendale and Seaford in south eastern Melbourne.  Many years ago, the wetland was considered useless swamps too difficult to develop. Today they are recognized as precious community assets. It is owned and managed by while the surrounding lands are owned and managed by the City of Frankston and the City of Kingston. This site is one of the largest freshwater wetlands remaining in the...
Fossil fuels are running out. As the world becomes more urbanised, the need for energy is growing. Fossil fuel depletion is an environmental issue which should be looked at seriously if the human population is to survive in a comfortable manner after relying on non-renewable resources for so long. Cuba is one small country (located south of Florida in the United States, and east of Mexico) which has set an example for the rest of the world, a model for keeping a nation running without access to...
Environmental issues effect every life on this planet from the smallest parasite to the human race. The reason for this is simple. A single disruption in the Earths delicate balance can mean certain destruction of the very place that cradles the lives of many species. What is not so simple is finding alternatives to the now dangerous and confronting acts of planet degradation that have been afflicted on the planet over recent years. One such issue that requires consideration is deforestation....
This document discusses the disposal of biomedical waste generally worldwide. Biomedical waste is hazardous waste, produced during the immunization, diagnosis or treatment of humans, animals or in investigative research. The disposal of biomedical waste is just as important, as the process that has led to its generation primarily due to the potential health and environmental risks that biomedical waste poses. Improper disposal of biomedical waste leads to the transmission of infectious agents;...
