Properties of paints Exterior paint is exposed to all types of varying weather conditions. Exterior paint is therefore required to provide protection against UV radiation of the sun as well as fungal growth. It’s made to combat mildew as well as fading. In addition, they have to be fade resistant as they face … Read more
Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard. Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable … Read more
The Human genome project was a large, international and multi-institutional effort that took 13 years from 1999 and $2.7 billion to produce a blueprint of the sequence of genes and space between genes that make up a typical human genome. Following were the observation of HGP (read)- 99% of the total human DNA is junk … Read more
Coal bed methane is found in the impermeable stone and is trapped in the coal seams. A significant portion of this gas remain as free gas in the joints and fractures of the coal seam. Large quantities of gas are adsorbed on the internal surfaces of the micropores within the coal itself Coal bed methane … Read more

Yamanaka factors (Oct3/4, Sox2, Klf4, c-Myc) are highly expressed in embryonic stem (ES) cells, and their over-expression can induce pluripotency in both mouse and human somatic cells, indicating that these factors regulate the developmental signaling network necessary for ES cell pluripotency. However, systemic analysis of the signaling pathways regulated by Yamanaka factors has not yet … Read more
Live vaccines are derived from “wild,” or disease-causing, viruses or bacteria. These wild viruses or bacteria are attenuated, or weakened, in a laboratory, usually by repeated culturing. For example, the measles virus used as a vaccine today was isolated from a child with measles disease in 1954. Almost 10 years of serial passage using tissue … Read more
Implantations of nanotransmitters and nanosensors within individuals have opened gates for monitoring and treating them at the microscopic level with the use of nanodevices. But this crosses traditional bounderies of care in the hospitals as persons can get the treatment done while siting in their homes . Pateients at home could have access to … Read more
