Sustainable Polymers Derived From Naturally Occurring Materials
Nearly 95% of monomers or chemical intermediates used today are based on fossilized carbon such as coal and petroleum. This has resulted in a high rate of depletion of fossilized reserves, continuous escalation in petroleum prices, environmental impact with the increase in emission of greenhouse gases, and accumulation of non-biodegradable waste on earth. Current global main challenges are movi...
متن کاملNaturally-Occurring Radioactive Materials (NORM)
Over the years there have been many occasions when it was asserted that coal-fired power stations emitted more radioactivity (from NORM) than was released anywhere in the nuclear fuel cycle. While having some basis in fact the claim is generally not correct now. Today the contention regarding NORM tends to be in relation to steel and other materials released from demolished industrial facilitie...
متن کاملNaturally-Occurring Radioactive Materials (NORM)
The main issue in view of NORM-impacted sites 1 is how such sites, e.g. radium contaminated sites, uranium liabilities, sites exploited for the mining of metals associated with NORM and wastes arising from industries processing or generating other kinds of NORM, are assessed and regulated. In view of the implementation of the new Basic Safety Standards (BSS), the regulations apply to the manage...
متن کاملNaturally-derived and bioinspired materials
Cell behavior and tissue function are influenced by the composition and architecture of their surroundings. These cues can drive normal processes during, for example, development, wound healing and homeostasis, or promote harmful processes including tumor growth and metastasis, fibrosis, disease and degeneration. Recent advances in materials synthesis, processing and characterization as well as...
متن کاملNaturally occurring ehrlichiosis in Egyptian dogs
Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...
