The bad effect of mobile towers in our life

today we are facing lot of problems and depression in our life mostly in urban areas do you know why this is so, it's because of the electro magnetic wave produced by the mobile towers which also pass through our body and as our blood contain iron this wave interacts with our blood causing severe causes

These wave also cause leakage in the coconuts and as consequence the water sips down and the sparrow are also disappering .

Women`s contribution in space

Even in the much demanding and 

tough field of space exploration women 

have made tremendous contributions. 

Most of these women went unnoticed even 

though they played an important role in 

the histor y of space exploration. 

It has been shown that biologically a 

female can do better in space 

exploration. In the environment of space, 

a woman, because of her nature, can 

adapt to various factors such as heat, 

spacecraft tremors etc better compared 

to a man. A woman is less prone to space 

radiations also. And a woman weighing 

120 pounds consumes less oxygen 

compared to a man of 160 pounds.

the lesser weight of women is itself a significant 

advantage in the environment of space. 

Men are also disadvantaged 

because they retain much higher levels of 

iron in the body than women, particularly 

in space, and this can reach toxic levels. 

Men in their thirties and forties are much 

more likely to develop the first signs of heart 

disease, a condition exacerbated by 

space travel. Women are protected from 

this by their comparatively high levels of 

oestrogen. 

Yet, there were several women who 

never got a chance to enter into space 

despite having passed the most stringent 

of tests. In 1961, 13 women aviators were 

extensively tested for their physical and 

psychological tolerance to the then- 

unknown rigors of space flight. The first 

woman to go through the Mercur y 13 

astronaut test was Jerrie Cobb. A 28-year- 

old pilot, with three world records, and 

7,000 hours of flying time, Jerrie Cobb had 

ice water injected into her ears to test her 

balance. She, as well as Wally Funk, were 

the only women who successfully 

completed the tests used for the original 

seven Mercury astronauts. In spite of these 

women completing all three of the 

phases, and 11 other women completing 

Phase I, they would never get the chance 

to go into orbit.

How does a petrol engine works?

THE working of a petrol engine can be explained by 4 strokes given below:                                                                                                                   

1.intake stroke:in this stroke,vapours of petrol mixed with air are admitted into a cylinder through the intake valve.this happens when the air pressure inside the cylinder decrease due to downward motion of the piston.the mixing of air and petrol takes place in carburetor.

2.compression stroke:at the end of intake stroke the intake valve closes and the piston starts moving up.The petrol-air mixture is compressed by the upward moving piston which heats the mixture.In high compression engines,the mixture is compressed to 1/8th of its initial volume.the efficiency of engine increases with increase in compression.

3.power stroke:After the compression stroke as the piston starts moving down due to momentum,fuel in the mixture is ignited by a spark produced by a spark plug.The temperature becomes high.The pressure increases to about 25 atmospheres.Due to high temperature and pressure,themixture expands pushing the piston down and in the process it does work.The temperature of the mixture falls  during expansion

4.Exhaust stroke:The exhaust valves opens up when the piston starts moving upward.Simultaneously,the spent gases are thrown out.The above four operations make one cycle of the heat engine.The cycle is repeated at rapid rate.The to and fro motion of piston is converted into rotational motion of wheels by the use of piston rod and crank
