Abstract Soil reflectance spectroscopy is a well known technique to assess soil properties rapidly and quantitatively both in point (Spectroscopy) and image (Imaging Spectroscopy (IS)) domains. The quantitative approach has been developed in the past two decades by many researchers and many papers have been published on this subject in the scientific literature. Basically‚ the quantitative approach has been adopted from other disciplines (e.g. food‚ textile‚ pharmaceutical); whereas the mapping

infection may also cause poor weight gain‚ malnutrition and learning problems. Ascariasis is an infection of the small intestine caused by Ascaris lumbricoides‚ a large roundworm. The eggs of the worm are found in soil contaminated by human faeces or in uncooked food contaminated by soil containing eggs of the worm. A person becomes infected after accidentally swallowing the eggs. The eggs hatch into larvae within the person’s intestine. The larvae penetrate the intestine wall and reach the lungs

Phytoremediation has shown to be very cost effective and a non-invasive alternative to chemical remediation of contaminated sites. The area where soil is the most polluted are residential areas‚ farm lands and industrial sites (Stephens 1995)‚ all these areas are inhabited by humans so it is essential that the toxic components in the soil are removed in a safe and protective manner. This is where our friendly plant friends come in‚ phytoremediation uses natural or genetically modified plants; often

allows greater magnification. Over all‚ the uses of both electron microscopes and light microscopes have increased the understanding of Cyanobacteria. Cyanobacteria are found in almost every conceivable habitat‚ from oceans‚ fresh water‚ bare rock and soil. They have the ability to occupy most habitats. However without sunlight they cannot survive therefore limiting there habitats to those that are not in total darkness. The majority of Cyanobacteria are aerobic photoautotrophs. To
