The Function of a Blank - Assignment Example It is mostly used for volatile organic compounds that are present in low concentrations. Condensation in the cold trap allows preconcentration for easier analysis by GC/MS Absorption is the process of transferring a gaseous compound into a uniform distribution in a liquid or solid. Involves the collection of gases, liquids, or solutes on a solid surface. Usually a porous solid is used, this provides vast surface areas. The less volatile a compound is, the more gas will be adsorbed. The quantity of a gaseous pollutant adsorbed by a given quantity of adsorbent depends on Concentration in the air over the surface, Surface area of the adsorbent, Temperature, Other gases competing for adsorption sites and Properties of the adsorbate. These methods of sampling are also referred to as the wet collection system. The most contaminated soil is used for the study of possible decontamination or to study the degradation or persistence of the contaminant. Some contamination may also favor other forms of land use than others. Therefore contaminated soil may be used for other applications Bio fixation involves the incorporation of particular organic material to aid in the regulation of other compounds that could be contaminants. An example of bio fixers is root nodules of some plants that fix nitrogen in the soil. Most organic compounds degrade naturally and are, therefore, termed to be biodegradable. Therefore, the concentration of biodegradable material reduces with time. ä ¸â‚¬ Foodborne illness is an illness that is carried in the food, to those who eat it. It may be caused by microorganisms such as Bacteria multiplying rapidly in food that is high in protein, such as meat or poultry. Temperature danger zones are temperatures that promote bacterial growth. The temperature danger zone ranges from between 40 ºF to 140 ºF (4.4 ºC-60 ºC) and food should be contained in these temperatures for more than four hours

Mondrian's Mathematical principles art Speech or Presentation

Mondrian's Mathematical principles art - Speech or Presentation Example Mondrian employed the very simple geometrical shapes and primary colors for expressing reality, nature and logic. His perspective of viewing things was different. He considered that it is possible to construct any kind of shape as long as there is a basic geometric one. Same is the case with colors; any color can be made by a combination of two or more of the primary colors, red, blue and yellow. A very common element of Mondrian’s art is the Golden Rectangle. This comes under the basic shapes and it has been used repeatedly by Mondrian in his artwork. The following compositions were created using the primary colors and both contain several golden rectangles. The first one was painted in 1942 and the second, right one in 1926 (Mondrian 1937–42). Basically, through his work Mondrian wanted â€Å"to achieve harmony through the balance of the relationships between lines, colors and planes. But only in the clearest and strongest way† (Ruhrberg, et al. 2000,
