The Great Oxygen Masks

Everyone would have seen the ER atleast from the outside. And those who have never had the misfortune to visit a hospital ever, would have atleast watched it in TV. And you would have watched people breathing with masks on their faces that is supposed to supply them with more oxygen than they could get from the atmosphere. The mask is cute, but where does the oxygen come from? In olden days, people used to store them in cylinders and release it to the maskthru a valve. But this is expensive, and filling oxygen in the cylinder is a big process.

Thats why there are portable oxygen concentrator, which takes oxygen from the air around us and makes it a concentrate and feeds it to the mask so that the patient can brethe easy. This is real good stuff.

How is Electricity Transmitted Part II

Electricity is generated in very high voltages. Something to the tune of 440, 000 volts. There is a factor in all electrical equipment called as the (I^2)R or the IsquareR loss. When you square the amount of current that flows thru a conductor and multiply it with the resittance of the conductor, the result that you get is in Watts, and that is a loss.

So if a 1 ampere current flows thru a conductor having a resistance of 1 Ohm, the resultant loss will be 1 watt. So, when a power station is generating power in megawatts, and with the transmission lines so lengthy and with the total resistances over kilometres running into 10s of 100s of ohms, if a lot of current flows thru the cables, the loss could be considerable. Therefore to reduce the loss, the corss sectional area of the cable should be increased, which would result in increase in an investment. So the best way to do is is to generate and transmit the power in very high voltages, and reduce the current and the loss.

All alternators are fed into a common bus. And there is usually a state grid or a national grid for every country, which is a common line, and this makes sure that all phases are in sync and all the generators in the country work uniformly. The generator’s output is fed into 3 phase transformers, which feed the lines that carry the power to the sub stations located at the outskirts of the cities.

Corporate Management

You cant do all the work on your own. You need people working under you, and you need to channelize all work, allot work to efficient people who specialize in their field. And there should be a head of all of them, who plans the work, and make sure that the company ultimately delivers good work.

Money is a return that can be expected. But what is life with just money? When you have power, or a great ability to make money with the team under you, you need recognition for that. With corporate performance management, an organization can understand and influence its business performance thru software, processes and measures of business success.

This award was created to highlight elite companies who creatively implement technology solutions and the vendors who facilitate that success. These award winners demonstrated a level of technological sophistication and innovation that moved them to a higher competitive level in advancing their strategic goals.
