Part One: Air Pollutants.

There are a number of elements that are responsible for air pollution. These air pollutants include greenhouse gases, Chlorofluorocarbons, and Nitrogen Oxides. Greenhouse gases are type of gases, which for a long time stay in the atmosphere thus trapping the sunlight causing global warming (Jeremy 192). Some of these gases include nitrous oxide, carbon dioxide, and methane result from burning of the fossil fuels in motor vehicles (Jeremy 94). Methane also comes from rice paddies and cows. Nitrous oxides results from decaying plants and industrial sources. The use of substitute sources of energy including wind and solar can be used in ...

Government agencies use contracting to execute complex projects that require technical expertise. Contractors have to go through an appraisal process that determines their suitability for the job. After appraisal, the most suitable applicant wins the contract. However, the contracting process can be subject to formal complaints. This calls for the establishment of mechanisms that resolve the arising disputes. Historically, there are two mechanisms for resolving formal disputes arising from business contracting: administrative and judicial processes.

The administrative means to resolving contract disputes are straightforward compared to the judicial process. The Contract Disputes Act of 1978 approves the use of ...

The life cycle assessment plays a crucial role in assessing the environmental impact of the whole systems of production from the life cycle point of view. Although some countries have applied LCA to the agricultural systems, its applications to the production of rice are ...

Is it fair to restrict the growth of developing countries because of climate change?

Climatic change is a fundamental problem that is affecting developing nations, as well as developed nations of the world. However, as Nath and Behera pointed that developing nations are likely to be faced with a greater incidence of the outcome of climatic change than developed nations. This is because developed nations have the resources to deal with the outcomes of climatic changes and are already setting up mitigation strategies with respect to it.
The earth has limited carrying capacity and therefore increased population growth is likely to do more harm than good. Restricting the growth of developing nations can be ...

Introduction Under broader definitions, horticulture is related to all activities that go on in the field. It is the growing of plants, flowers, fruits, and vegetables.

Its average replicative lifespan is around 36 cell divisions (“Saccharomyces cerevisiae,” n.d.).

Two critical physical requirements are:

- Saccharomyces cerevisiae requires acidic pH to grow. The optimum pH for S. cerevisiae is 4−6 (Olivero, 1982, p. 2726). Its growth rate drops dramatically when pH is increased above 6.5 (Olivero, 1982, p. 2726). This requirement allows the budding yeast to thrive in ...

Introduction.

A combustion engine can be defined as any engine that operates through fuel burning. The difference between a combustion engine and steam engine is that the latter uses steam for operation while the former uses gasoline. Combustion engines also use fueled gases such as hydrogen, propane, methane etc which are components of diesel. Combustion engines run on one type of fuel, and may require a series of adaptation to adjust to fuel/air ratio to use other forms of energy (Agrawal, 2006).
The combustion process starts in the gasoline cylinder where a mixture of air and gasoline is sprayed. The mixture is ...

Introduction

Biomass is a biological material obtained from a living organism or a recently living organism. The word biomass is derived from two Greek words; bio meaning life, and maza meaning mass (Demirbas, “Fuels from Biomass” 43). Biomass means non-fossil and bio-decomposable organic matter (originating from plants, animals and microorganisms). The products, byproducts, residues and waste from agricultural processing, all constitute biomass. Bio-waste simply means non-fossil and biodegradable waste that is composed of organic matter. Bio-wastes include food and kitchen wastes, garden and park wastes, and wastes from food processing plants. Bio-waste is therefore an element of biomass.
Non-fossil wastes that are ...
