Electronic equipment is consisting of various components like terminal and connector. A Socket is connector electronic component and there are thousands of different list of Socket are available depending of different part number. The Resistors are converts the electrical energy into heat energy and there are different kinds of Resistors are helpful for different electronic uses. Some Resistors are fixed valued and others are variable valued. The heating elements are also known as resistors and they help in transmitting using electric energy. There are some interesting resistor are available as Tharmistor. They can change their resistance power with the change of any change in the temperature of its environment. Various electronic companies make electronic parts with different parts numbers. Semiconductors are just other insulators if they are very pure and especially at very low temperature, but their conductivity can be greatly increased by adding a small amount of impurity. This process in know as doping for making a semiconductor. Then they can be use to make electronic devices diode, transistors or Integrated Circuits.Two type of semiconductor metrical are obtained depending on various types of impurities. They are like n-type and p-type semiconductors. The n-type semiconductors are doped with silicon (Si) and Phosphorus (P). The p-type semiconductors are doped with silicon (Si) and boron (P). In practical field there are thousand of semiconductors are developed for different uses by different manufacture and it is Hard to Find Semiconductors for right purpose.

Global Warming- We are living in an artificial environment

The earth is a small plant in the universe. This is the only place in the universe where life ids possible. It is generally believed that the earth is about 46oo million years old. Life appeared in this earth more than 3000 million years ago. The science and technology made t tremendous progresses in the resent century and in the previous century. The natural diversity of the earth made it so special as a living place. The earth atmosphere is consisting of the essential gases like Nitrogen and oxygen. The valued of carbon –di-oxide is very important fro the all plants. The plants made their own food with the help of carbon di oxide. When the life began on the earth some 3100 years ago the earth atmosphere probably contained nitrogen ammonia, hydrogen, carbon di- oxide and carbon – monoxide. Some other valuable gases are hydrogen sulphide, methane but no free oxygen was there in the atmosphere. All the volcanoes were very active at that time. They contributed a large proportion of gases in the atmosphere.

As there was no oxygen there was no Ozone layer. Ozone is formed by the action of shortwave radiation oxygen. The UV ray from the Sun can easily enter into the earth’s atmosphere. This UV light m made a well contribution in the formation of life on the earth. The climate of the earth at that moment was very dangerous. The frequent thunders and electric discharges were common and naturally occurred at that time. Under the influence of energy in the form of UV ray and electric discharge and gases from volcano and variable temperatures some how synthesizes the organic molecule called amino acid which is unit of forming a protein molecule. The important comportment of every living cell is DNA and RNA. They are formed from some inorganic substance. After 3100 million year human being are the superior in the living kingdom. Only human can save this earth… almost one percent of the atmospheric gases are now green house gases. .. Ozone is a minor constituent of atmosphere but play an extremely significant role by providing a protection screen against deadly UV radiation n. thus making life on land possible. The maximum concentration of ozone is around 10 ppm in the stratosphere where it exists as a band at altitude of about 25-30 km. carbon dioxide is a colorless, non-toxic gas that readily dissolves in water.

How’re, since about 1850 the level of CO2 in the atmosphere has been rising dramatically rises. This produces a deep impact on the world climate. The two most important reasons for this increases in carbon di oxide in the atmosphere are estimated that from about 290 ppm in 1850. Now it has increases about 334 ppm in 1979it is going to be double in the next 10 years. The green house gases produce form various sources like automobiles, industries and refrigeration and air conditioning. The CO2 has some unique properties like it can absorbing the outgoing heat in from of infrared radiation. Hence increases in carbon dioxide in the atmosphere would result in a warming of the earth. The warming is popularly referred to as greenhouse effect. It m takes its name from the warming in green houses where sunlight freely enters through the glass panes, but the heat generated in the form of infrared radiation in largely absorbed by the same glass panes. In the other words CO2 acts much as the glass pans do preventing heat to escape. It is the green living style that can reduces the production of green house gases and consequently the heat generation due to green house gases will also reduced. We need more technology that will find energy efficient way to get a green eco-friendly living.

Harmful chemical substances of E- Waste

E- Waste means the electronics waste material that produces different chemical substances harmful results for our environment. E-waste has become one of the most power full threats for the world environment.

Mercury Hg, leads Pb are the most powerful harmful substance of e-waste. Laptop and UPS batteries contain this kind of substances that are very awful for Health.

The technology is changing day buy day we are depending of electronic and electrical equipment fro our daily needs. Therefore the numbers of electronic devices are increased 20 – 45 percent I n the recent decades. These electronic junk are not recycled properly and due to less space in we storing these waste in our nearest living places. Risk less management of e-wastes is causing a hazardous for any locality. The scientific solution of e- waste problem is not just collecting all the e-waste and throw that in a lonely place is not a solution. Different organizations are working to develop environment friendly e-waste solution for any institute of offices that refused to use the e-waste. Some organization never want to disposed there e-waste as they contain many important data about their employees – if it is a educational organization than e-waste sometimes contain important data that need s some kind of security, before damaging or recycling those data a storage devices they want proper destruction of these stored data. The e-wasted are recycled in more eco-friendly manners.
