concentration first results in the formation of mixed choro-bromo species to fully brominated ones (Hua et al., 2006). It has been reported that brominated DBPs so formed are more carcinogenic as compared to the chlorinated ones (Uyak & Toroz, 2007). Water and wastewater treatment processes remove organic carbon but bromide ion is quite resistant to be removed by these and hence ultimately ratio of bromide ion to total organic carbon (TOC) increases. This increases the fraction of brominated DBPs (Roccaro

The popularity and rise in applications of electronic devices may be a cause of electromagnetic (EM) environmental pollution [1-4]. While EM fields are needed for many electrical instruments to operate, they can wreak havoc on the operation of other nearby electrical devices. In addition, some studies exhibit that EM radiation can harm human health [5-7]. A simple solution to overcome these problems is to provide EM shielding via coating the sensitive electronics parts or EM radiation sources by

Abstract— The pump is one the most common machine in all industries, whether its small scale or heavy industries. In the present scenario of energy crisis, it would be advisable to conserve, even the minute proportion of energy. In the centrifugal pump, the inefficiency is mainly due to the hydraulic losses in its various components. In this phase, mathematical analysis is done to predict the performance characteristics curve of the single stage centrifugal pump. This methodology is based on the

The water from this process can then be used to produce oxygen and extra hydrogen through an electrolysis reaction. The oxygen produced can be used for breathing in the Mars atmosphere while the hydrogen can be combined with either the crew’s expended CO2 or atmospheric CO2 in order to produce more water. This is the basis of the Sabatier Reaction, which is the most credible way for space dwellers to receive the oxygen required for life in space.3,4 The water produced from the Sabatier

Salt What is it exactly? Salt is the residual left when waters from ancient oceans evaporated in shallow seas or marginal basins. http://www.waterencyclopedia.com/Mi-Oc/Mineral-Resources-from-the-Ocean.html Where is it found or used geographically? It is found in salt mines or in shallow water that is mineral rich. http://en.wikipedia.org/wiki/Salt How is/was it used? Salt is used in many different ways. Salt is used in the seasoning or flavoring of food while it also can be used to preserve

intense rays of the sun on an amazing summer day. I am calmed by the sounds of the ocean, and the breeze softly touching my skin as warm water splashes my legs as people dive in the ocean. As I am sitting in the chair reading a book, I can see the sight and smell of the salty warm water calling my name. I run as fast as I can to the endless clear blue water. Floating peacefully among the waves, I am looking at the clear blue sky above me, birds are flying freely in the sky with no worries just

Water is the natural resource that man and all other living creatures cannot do without. In fact, it is one thing scientists look for in other planets to confirm possible sources of life. For us humans, it is so important that in 1995, World Bank Vice President Ismail Serageldin said that “the wars of the next century would be fought over water” and not oil. Unfortunately, water is also one resource that we always take for granted and end up wasting through inefficient use and pollution.To make matters

Functions of Potassium in Plants P When water supply is short, K is pumped out of the guard cells. The pores close tightly to prevent loss of water and minimize drought stress to the plant. If K supply is inadequate, the stomates become sluggish – slow to respond – and water vapor is lost. Closure may take hours rather than Potassium (K) increases Enzyme Activation minutes and is incomplete. crop yield and improves Enzymes serve as cataAs a result, plants with an quality. It is
