The Japanese have always loved fresh fish. But the waters close to Japan have not held many fish for decades. So the fishermen had to go further out to sea to catch their supply of fish, the fishing boats got bigger and bigger. The farther the fishermen went, the longer it took to bring in the fish. If the return trip took more than a few days, the fish were not fresh and they lost their fresh taste. To solve this problem, fishing companies installed freezers on their boats. They would catch the fish and freeze them at sea. Freezers allowed the boats to go farther and stay longer. However, the Japanese could taste the difference between fresh and frozen and they did not like frozen fish. Also, the frozen fish brought a lower price. So fishing companies installed fish tanks. They would catch the fish and stuff them in the tanks, fin to fin. After a little thrashing around, the fish stopped moving. They were tired and dull, but alive. Unfortunately, the Japanese could still taste the dif...

If life is a race, fools are winning. The wise and intelligent people don’t participate in the rat race of life since they know that even if you win the race, you are still a rat. They rather spend their time in this world to live their life purposefully doing the things which they love to do and transforming the world to become a better place for themselves and for others. Fools, however, keep running the race of life till they die. Let me narrate you a story "How Much Land Does a Man Require?” authored by by Leo Tolstoy to explain this foolishness of man. There was a peasant named Pahom. A landlady in the village decides to sell her estate, and the peasants of the village buy as much of that land as they can. Pahom himself purchases some land, and by working on the extra land is able to repay his debts and live a more comfortable life. He is soon introduced to the Bashkirs, and is told that they are simple-minded people who own a huge amount of land. Pahom goes to them to buy as...

When your once new computer starts to become the " new clunker " in your life, it's time to revise what junk and viral matter are slowing down the cogs in your machine. Over time, computers do slow down if care is not taken to address the problems that mount up. Each is easily taken care of, provided you know how and why. What is Slowing Down Your Computer? 1 Be aware that the majority of the machine issues are the aftereffect of infections, spywares and the registry over-burden. If care is taken to do regular upkeep checks, this can be balanced out and problems dealt with and removed. Windows PCs tend to slow down as applications are introduced and utilized. Whether you are utilizing a processor, a spreadsheet, surfing the web, playing games or whatever else, hard drives loaded up with makeshift documents that don't generally get evacuated when no longer required will slow down considerably. Hard drives can succumb to wear and tear over time as well. 2 Keep the syste...

The human retina is a thin tissue composed of neuralcells that is located in the posterior portion of the eye. Because of the complex structure of the capillaries that supply the retina with blood, each person’s retina is unique. The network of blood vessels in the retina is so complex that even identical twins do not share a similar pattern. Although retinal patterns may be altered in cases of diabetes, glaucoma or retinal degenerative disorders, the retina typically remains unchanged from birth until death. A biometric identifier known as a retinal scan is used to map the unique patterns of a person’s retina. The blood vessels within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting. A retinal scan is performed by casting an unperceived beam of low-energy infrared light into a person’s eye as they look through the scanner’s eyepiece. This beam of light traces a standardized path on the retina. Because retinal blood v...

Torrents are peer-to-peer file transfer protocol. That means, there is no central source for the files, people download files which are being uploaded by others (in real time). Seeds : Number of peers who have already downloaded the files, and are currently uploading them. Peers (or Leechers) : A leecher is any peer that does not have the entire file and is downloading the file. Trackers: A tracker is a server that keeps track of which seeds and peers are in the swarm (swarm: all peers sharing a torrent - uploading or downloading). Pieces : This refers to the torrented files being divided up into equal specific sized pieces (e.g., 64kB, 128kB, 512kB, 1MB, 2MB or 4MB). The pieces are distributed in a random fashion among peers in order to optimize trading efficiency.

Antibiotics work by affecting things that bacterial cells have but human cells don't. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall. Antibiotics either stop bacteria from reproducing or destroy them. Before bacteria can multiply and cause symptoms, the body'simmune system can usually kill them. Our white blood cells attack harmful bacteria and, even if symptoms do occur, our immune system can usually cope and fight off the infection. Antibodies don't work on viruses , Viruses insert their genetic material into a human cell's DNA in order to reproduce. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus.

The electricity bills are nothing but energy consumption bills and not power consumption bills. Energy=Power * time When we say we have consumed 1 unit of electricity, that means we have consumed 1kWhr of electrical energy. 1 Unit= kilo watt hour. So, for example if you use 10 watt of lamp for 100 hours, the electricity consumed will be 1000 watt hour. That is 1kWhr, nothing but 1 Unit of Electrical Energy.
