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

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

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

separate the four components of a mixture of sand, salt, iodine and iron filings and determine the % of each by mass Brief procedure: The stepwise procedure was developed based on unique properties of each component: Salt: soluble in water Sand: insoluble in water Iodine: sublimes to vapor Iron: attracted to magnet We weighed out ~2g of the mixture in a 250mL beaker and chose to separate the iron first using a magnet. Since the iron sticks strongly to the magnet, the beaker + mixture was then

In other words, it increases the demand of the resources and thus, causes waste generation. Improper of waste management will giving effects to environmental. For the environmental aspect, it causes air pollution, water pollution, soil pollution, visual pollution, noise pollution, odour pollution and explosion hazard (Ramachandra, 2006). Besides that, disposing the rubbish will waste the potential raw materials and energy that used in making the items. Recycling is

Snow Blowers and Throwers are machines for removing snow from unwanted areas like roadway, runway, sidewalk, railroad track or driveway. Both snow thrower and snow blower are slightly different from each other, snow thrower uses a single stage to remove the snow and snow blower uses two stages to remove snow. These machines either use electric power, diesel or gasoline as fuel source to throw snow to another location. Snow throwers ranges from the very small size, capable of removing only few inches
