With special reference to Jharkhand State of India . By Dr. Nitish Priyadarshi. Palaeoclimatology, the study of climates during the geological past, is one of the most topical areas research in the geoscience at present. The threat of future climate change caused by higher levels of greenhouse gases, which would drastically alter many aspects of our environment, has prompted much research to try to understand how our complex climate system works. Only by understanding how climate has evolved over million of years can we identify important cycles with a frequency in excess of the short climate records we possess. These climate cycles have the potential to have a profound effect on our environment. The determination of past climate parameters by the use of paleohydrologic conditions is an important phase of paleoclimatology. The present climate of any local area, on any continent, and around any lake basin, depends on the same factors which controlled Pleistocene climate. The study of p...
A small slide show on concept of atomic power of ancient India. by Dr. Nitish Priyadarshi Our own culture, if we assume a starting point of 4000 B.C. has progressed from primitive agriculture and herding to nuclear fission is only 6,000 years. Considering the age of mankind, there has been ample time for other cultures to have arrived at a level roughly corresponding to ours. A re-examination of some of the ancient records that have come down to us might give some indication of man kind having previously attained our present aptitude for destruction. While there are hints of great blasting of the earth´s surface in the Bible (Sodom and Gomorrah), the Greek myths, and many of the legends of the Indians of North and South America, it is in the ancient records of India, copied and recopied from prehistoric antiquity, that we find, described in considerable detail, the use and effect of what closely resembles atomic explosions in warfare. Unexpected references to such recent developm...
Assessment of helium reservoir may be under taken in the Jharkhand state. By Dr. Nitish Priy adarshi. Fig: The above pictures are of Surajkund area in Hazaribag district in Jharkhand. Rocks of Jharkhand State in India which are mineral rich can also be used for trapping Helium deposit. In Jharkhand helium has been reported in the gases of different thermal springs of Hazaribag district. In Jharkhand, concentration of helium is highest in thermal gases of Surajkund (3.63 mole %) followed by Charhi (3.38 mole %), Duari (2.95 mole%), Barkagaon (0.29 mole %)and Badam (0.09 mole %). Surajkund hot spring (also called Surya Kund) is a natural hot spring in Belkapi gram panchayat of Barkatha community development block in Barhi subdivision of Hazaribag district in the Indian state of Jharkhand. Mineral radioactivity plays an important role in the natural occurrence of helium. Helium is an end product of radioactive decay. Helium is also known from the damp of many coal mines. The release of he...
