INTRODUCTION Bananas are one of the most important food crops in most of the African countries. About 75% of the farmers grow the crop on 1.3million hectares in Africa. Most of this production is for local consumption. They are amongst the most important commercial subtropical fruits grown in South Africa and are planted for sale in local markets or self-consumption and only a fraction of all bananas are sold in the world markets. The production technologies used for small scale and commercial…
ABSTRACT: Acid mine drainage has a prominent and damaging effect on the environment. This paper outlines the environmental impact, the chemistry behind the acid generation, and methods of treatment. The objective of this paper is to educate the reader about acid mine drainage, and what can be done to reduce this pollutant. INTRODUCTION/BACKGROUND: Acid mine drainage (AMD) often occurs at abandoned mining sites. Acid generation is the result of combining certain minerals, water, and an oxidant.…
Turbidity: - Turbidity is a degree of water clarity. Turbidity is defined as an “expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample”. Nephelometers are used to measure the intensity of light scattered by contaminants present in water such as suspended and colloidal solids like clay, silt and microscopic organisms. Turbidimeters using the principle of nephelometer compare the light scattered due to…

Most lawn care services will offer a variety of options when creating an agreement. You may only schedule cutting the grass and removing the weeds each month. Other options might include winterizing, re-seeding, cleaning up leaves, pruning trees, aeration, or fertilization. It all depends on the different services that they…
dependent on how much organic matter is needed to be broken down. Decreased the DO levels and result in mass “fish kills”. On the contraire to this, increased DO levels have little impact on drinking water other than slightly improving it’s taste. The aeration of water can be caused by wind, waterfalls, or other forms of running water. Man-made causes from an aquarium air pump to a hand-turned waterwheel. The dissolved oxygen sensor is attached to a to a data logger and the use of two tests on…
in the cell wall. The amount of Calcium in soil will depend on the parent material and extent of weathering. Immobility of Calcium will be seen at the growing tips of the plant. Plants require a continuous supply of Calcium; however, inefficient aeration and temperature will affect this. Calcium…
which evolve a high rate of production of lipase from the cultivation of Acinetobacter radioresistens on Tween 80. OBJECTIVES To find out in details the requirements and factors that affect the yielding of A.radioresistens lipase. Agitator speed, aeration…
We all work and study very hard. After a long week of that, it can be nice to sit back with some friends and enjoy a couple of beers. Imagine you have some friends over, but instead of offering them a bottle of Budweiser or corona, how cool would it be to offer them a bottle of beer you made yourself? Making your own beer can be a lot of fun. I like it so much I recently helped out at a brewery down the block from me over in Ridgewood. We made hundreds of gallons of beer in one day, but I…
