The storm was nearly 400 miles wide‚ with the highest recorded wind gust at 104 mph. Overall damages were estimated in the $1.0 billion dollar range‚ and three deaths were attributed to the Category 3 storm. Copyright © 2005 by The McGraw-Hill

Then he lingers‚ with zest‚ on the walls and ceilings‚ lavatory tiles which had been white about fifty years ago‚ and now encrusts with soot‚ coats with the remains of a dirty liquid which might be either atmospheric humidity mingled with smog or the result of a perfunctory attempt to clean them with cold water. Above them‚ gloomy vaulting from which dingy paint peels off like scabs from an old wound‚ sick black paint leaving a leprous white undersurface. Beneath the

In this experiment‚ the scientists will research and test which of the four substances is the most efficient at absorbing water in cucumbers. The independent variable is the different substances being used. The dependent variable in the experiment is the amount of water absorbed. There are many constants including the same brand of cucumber slices‚ the same amount of each substance applied‚ the same measuring tools being used‚ and the same observation time. The control of these scientists’ experiment

this is much more precious first-hand experience. Also‚ museums and galleries are the best place to protect those precious antiques‚ which may be damaged without proper and professional preservation. For instance‚ without moderate temperature and humidity‚ a piece of silk clothes in the Ming dynasty would loss its color gradually and even break into pieces. Moreover‚ many museums hold special exhibitions on specific topics regularly‚ with experts invited to give lectures to the public. Such experience

The weather becomes cool and pleasant for some time though there is humidity in it. With the onset of rains the grass starts growing everywhere. There is greenery everywhere. Farmers sow summer crops that make the fields also green in a month or so. After the rains it is again hot for a month or so. This period is known as

The name comes from the praying like position in which the insect holds its long‚ jointed front legs while at rest or waiting for prey. The three common species of mantids in North America are the European mantis (Mantis religiosa)‚ the Chinese mantis (Tenodera aridifolia sinensis)‚ and the Carolina mantis (Stagmomantis carolina). There are many ways to distinguish between these three species

mostly water starved‚ so humidity plays a larger role in their biology. If there is little or no sunlight then plants may wither and die from not being able to get enough sunlight to do photosynthesis. Many archaebacteria require very high temperatures‚ or pressures‚ or unusual concentrations of chemical substances such as sulfur‚ because of their specialization into extreme conditions. Certain fungi have evolved to survive mostly at the temperature‚ the humidity‚ and stability of their environment
