mechanisms are designed to reestablish homeostasis when there is an imbalance. The Home Heating System 1. When the temperature of a room decreases below a set point‚ the thermostat electrically starts the furnace. 2. As the temperature of the room rises to the set point‚ the thermostat shuts down the furnace. 3. As the room cools‚ step one is repeated. There are three components to this system: 1. The Sensor which detects the stress. 2. The Control Center which receives information from the sensor and

GENERAL WORKING AND DESCRIPTION OF COAL HANDLING PLANT In thermal power station‚ Coal is a principal fuel and hence a careful thought is given to the design and layout of the coal handling plant. As the consumption of coal is very large‚ the design and layout of a coal handling plant should be simple but robust with a view to reduce the maintenance and running cost to the lowest possible figure consistent to reliability. Mode of Coal Transportation : Coal is brought to the power station by three

Introduction Brasses are copper zinc alloys. It is a substitutional alloy. Brass has higher malleability than copper or zinc. In general‚ they have good strength and corrosion resistance‚ although their structure and properties are a function of zinc content. The relatively low melting point of brass (900 to 940°C‚ depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc‚ the properties of the brass can

When the King ordered for those who do not worship his golden statue to be killed‚ Shadrah‚ Meschach and Abednergo were ordered to be burned in the furnace that would be heated up 7 times more than customary when they refused to worship the statue. After being put into the furnace the king stated “I see four men unbound‚ walking in the middle of the fire and they are not hurt; and the fourth has the appearance of a god” (Daniel 3:25). This demonstrates that with

Pakistan’s Energy Crisis EconomySouth AsiaPakistan August 31‚ 2013 By Shabbir H. Kazmi Energy shortages are hobbling the economy and contributing to unrest. But the country has options. Pakistan is in the midst of one of the worst energy crises in its history. This is both slowing the pace of economic activity and causing public unrest with prolonged outages of electricity and gas. Capacity utilization in some key industries has fallen to nearly 50 percent. Worst affected is the fertilizer
