What is Dialysis?

-
The chemical reactions in our body produce waste products, which are by-products of these reactions. These have to be removed from the body, otherwise they would have harmful effects on us. The kidneys are a perfect filter which perform the function of removal of waste products through the urine. Sometimes, when the kidneys get infected and do not function properly, the person starts suffering which can lead to his/her death. Such people are put on to artificial kidneys, also known as dialyser. Dialyser is a machine that filters the blood of harmful substances. Blood from a blood vessel is drawn into the dialyser and then purified to be fed into another blood vessel of the body. Such people have to be dialysed after every 2-3 days. Damaged kidneys are also replaced either from a donor or a dead person.

Why is Venus so Hot?

-
Image
T he planet Venus is named after the Roman goddess of beauty and love. It is the brightest planet in the Solar System. It is visible as a star. Venus is much hotter, because it is much closer to the Sun. The atmosphere there is 90 times thicker than that of the Earth and the surface is hidden in a white cloudy cloak. This thick atmosphere acts like a blanket which holds back the heat of the Sun and turns the midday temperature to 4800C. The atmosphere on Venus consists mainly of the carbon dioxide gas which acts as a greenhouse roof , trapping the Sun's heat. The rocks on Venus are hotter than boiling water. Above the rocks, winds blow at a speed of 320 km/hour .

When were the First Spinning Machines Invented?

People in the olden days used to spin thread by hand . They pulled fibres out of cotton and wool and twisted them together into thread. Spinning machines were invented in Britain in the 1700s. These machines had rollers turning at different speeds to twist the fibres into yarn. James Hargreaves in 1764 produced the first successful spinning machine. It was the hand-powered jenny which produced thin yarn. Richard Arkwright's water frame of 1769, powered by water wheels, gave a sturdy thread. Samuel Crompton combined these two spinning machines in 1779 , to make the spinning mule, which could spin many kinds of yarn. These machines were the precursors of the Industrial Revolution .
