History Of Refrigerators

History Of Refrigerators REFRIGERATION.   The preservation of winter ice, principally for cooling drinks in summer, was practiced from antiquity, when ice was stored in insulated caves. Ice cooling was so popular in America that, within a decade of the Revolution, the United States led the world in both the production and consumption of ice. As the use of ice was extended to the preservation of fish, meat, and dairy products,  ice production  became a major industry in the northern states, and ice was shipped not only to the southern states but to the West Indies and South America. By 1880 the demand in New York City exceeded the capacity of 160 large commercial icehouses on the Hudson River. This industry reached its peak in 1886, when 25 million pounds were  "harvested"  by cutting lake and river ice with horse-drawn saws. The advent of mechanical refrigeration in the nineteenth century began a slow decline in the ice trade.

Lifespan Of Rocks

Lifespan Of Rocks Investigating the lifespan of wild animals is extremely difficult. Since 1986, some  rock ptarmigans  in the Tateyama region have been fitted with leg bands, making it possible to recognize individuals, and in this way we have been able to understand a little bit more about their lifespan. However, there are too many variables to be able to establish a definitive average lifespan. Sometimes nests are attacked by stoats, or flooded by severe rains, preventing eggs from hatching.  Chicks and juveniles  have a high rate of early death from cold or attack by predators, so the average lifespan may actually be only a few months. What is now known is that for both males and females that live through their first winter, the average length of survival is about four years.There are, however, many records of individuals living for long periods of time in  Tateyama.  The longest-lived individuals observed to date are a male that lived for 13 years and a female that lived for 12 y...

Precious Stones

Precious Stones Precious stones  is a name that is usually used in reference to four types of gems: diamonds, rubies, sapphires, and emeralds. Some people have included opal, jade or pearls in the "precious stones" class, but these have not received persistent and widespread use. Separating stones into "precious" and "semiprecious" classes has led many people to believe that "precious stones" are more important and more valuable than " semiprecious stones ." This idea has somewhat been supported by the fact that diamonds, rubies, sapphires and emeralds account for over 98% of the dollar value of U.S. gemstone imports for consumption reported by the   United States Geological Survey
