Serious Effect Of Global Warming

IN many areas, people are changing the earth and causing great harm through pollution. Forest are cut down to produce farmland. But in some places, besides amn made havoc, rain and water make newly exposed soil thin causing soil erosion rending the soil infertile. Factories, vehicles and homes burn fuels that release gases into the air. The so-called greenhouse gases trap heat. They cause global warming and change world climates. Other kinds of pollution include the poisoning of rivers and seas by factory and household wastes. Air pollution occurs when gases such as carbon dioxide are emitted into the air by factories, homes and offices. Vehicals also cause air pollution, which produces city smogs, acid rain, and global warming. Pollution of rivers also affect people and environment. When factories pump poisonous wastes into rivers, creatures living near the river's mouths, such as shellfish, absorb poison into their bodies. When people eat such creatures,they, too, are poisoned. Coral reefs and mangrove      swamps are also breeding places for many fishes. The dstruction and pollution of these areas is threatening fishes in the oceans.Global warmimg hasworst effect on Island nations.

Dates for Health and Strength

Date is one of the oldest fruits know to man.In mesopotamia excavations have revealed 5000 years old clay tabletes giving detailed instruction for growing date palms. The date palm is symoblic of West Asia, so much so that it finds frequent mention in the Bible. Over the centuries it travelled far and wide from the land of its birth.Today it is grown in several counties in the world including Spain, Italy,China and USA, sometimes at an altitude of 1500 metres. Date palms are found growing naturally all over India particularly along streams. In India several varieties have been tried but only dates with a moderate heat requirement have been successful. Date is a food item of high nutritional value, packed with natural sugars in the form of glucose and fructose,available for immediate absorption by the body. Abot 70 persent protien, 2.5 persent fat and some minerals. Milk and dates make a complete meal.  

Evesest Climbers Log Lowest BloodOxygen Level

British doctors  scaling Mount Everest have Measured the lowest human blood oxygen levels ever recorded, according to findings published recently. The study in the New England Journal of Medicine's January 8th issue could help critical care docters revaluate treatment for long term partients sufferingfrom respiratory distress syndromes, cystic fibrosis, emphysema,and other serious illnesses, many of which force their hosts to adapt to low oxygen levels in the blood. The blood samples were taken just below the summit of Everest,at 8,400 meters above sea level, by the caudwell Xtreme Everest team on an expedition led by University college London doctor. Four team member drew samples from the femoral artery in the groin, and the blood was quickly brought down and analyzed in a science laboratory set up in the term's camp at 6400 meters. The team intended to take the samples on Everest's 8,848-meter summit but severe conditions including temperature at minus 25 degrees celcius and winds above 20 knots forced them to a slightly lower elevation.

Miranda Moon Of Uranus

Miranda is a large moon of the planet Uranus. Mrianda orbit Uranus at a distance of about 130000km. Miranda completes one orbit in about 34 hours. miranda's orbit is circular and slightly tilted relative to Uranus's equator. because the planet's equator is tiled relative to its orbit around the sun, Miranda's orbits of most other words in the solar system. Miranda is spherical, measuring about 472km in diameter. The moon is about one eight as wode as the earth's moon. measurements of Miranda's densityindicate that it is about half ice and half rock. miranda's surface is wildly varied. One of Miranda's surface features is Verona Rupes,  cliff rising 15km high. There are also canyons 20km deep and very old regions with craters 30km across. Probably the most distinctive feature on Miranda are Inverness Corona, Elsinore Corona, and Arden corona, geoloogically young system of ridges and grooves.

Veda – Ancient Hindu Sacre Literature

Veda which in Sankrit means knowledge is the most ancient sacred literature of Hinduism,or individual books belonging to that literature.This body of ancient literature consists primarily of four collections of hymns, detached poetical portion, and ceremonial formulas. The collections are called the Rig-Veda, the sama-Veda, the Yajur-Veda and the Sama-Veda and the Atharva-Veda. They are known also as the Samhitas roughly "collection". The four Venda were composed in Vedic, early form of sanskrit. The oldest portions are beleived by scholars to have originated largely with the Arayan invanders of India some time between 1500 and 1000BC;however, the Vedas in their present form are belived to date only from the close of the 3rd century BC. Before the writing down of the present texts, sages called risbis transmitted the Vedic matter orally, changing and elaborating it in the process. Large masses of material probably taken from the orginal Aryan milieu or from the Dravidian culture of India were preserved, however, and are distinguishable in  the texts. The first three Samhitas  are primarily ritual handbooks that were used in the Vedic period by the three classes of priests who officiatged at ceremonial sacrifies. The Rig-Veda contains more than 1000 hymns  composed  in various poetic meters and arranged in ten books. It was used by the botri or reciters, who invoked gods by reading its hymns aloud. The Sama-vedacontains verse portionstake mainly from the Rig-Veda.

Ruby Precious Stone

     A ruby is a pink to blood-red gemstone,a variety of the mineral corundum aluminium oxide. The red color is caused mainly by the, presence of the element chromium.its name comes from ruber,Latin forred.Other varieties of gem -quality corundum are called sapphires.The ruby is considered one of the four precious stones,together with the sapphire,right the emerald, and the diamond. Prices of rubies are Primarily determined by color. The brightest and most valuable "red" called pigeon blood-red,commands a huge premium over other rubies of similar quality. After color follows  clarity: similar to diamonds a clear stone will command a premium, but a ruby without any needle-like rutile inclusion will indicate that the stone has been treated. Cut and carat also determine the price. Rubies have a hardness of 9.0 on the Mohs scale of mineral hardness.Among the natural gems only moissanite and diamond are harder, with diamond having a Mohs hardness of 10.0 and moissonite falling somwhere in between ruby and diamond in hardness.

Extra Solar Planets

Extrsolar planets which are also called exoplanets are planets orbiting starts other than the sun.Astronomers  have afound more than 160 such planets.Finding and studingextrasolar planets helps astronomers learn more about the formation of our solar system. It also constributes to the study of possible life in the univerese,because life  is more likely to develop on planets then in the extremes of  stars and empty space.  Astronomers did not develop reliable techniques to find extrasolar planets untils the 1990s, but more than 10 new solar systems were dicovered within the first few years of searching. Many astronomers believe that almost every sun like star  has a solar system at some point in its development.  Astronomers have found that most young stars are sourrounded by disks composed of dust and gas. Some of these disk around the star Formalhaut, show an empty space in the disk. Astronomers believe that dust in this area could be in the process of condensig into a planet. By studying our solar system,astronomers developed a theory of how solar systems  form known as the core accretion theory.However,many of the extrasolar planets and disks of dust around other stars do not seem to conform to this theory.The theory states that a disk of dust and  gas collects around a star as the star forms.Bits of dust in the disk collide and stick together,forming larger and larger chunks of rock and ice.
