Sludge, soil and leachate samples collected from a chromium-contaminated tannery waste dumping site in Kanpur, India, were found to contain considerable amounts of Cr(VI), despite the fresh tannery sludge containing little or no Cr(VI). Literature reports suggested that dry Cr(III) precipitates could be converted to Cr(VI) when heated in the presence of(More)
Self-emulsifying drug delivery systems are isotropic mixtures of oils, surfactants and co-surfactants. Sometimes co-solvents are also incorporated to increase the solubility. That is why SEDDS are also becoming important tool in novel drug delivery since last couple of years. The problems of low bioavailability issues associated with poorly water soluble(More)
Transdermal drug delivery systems have evolved as a successful alternative to systemic drug delivery. Despite their relatively higher costs, transdermal delivery systems have proved advantageous for delivery of selected drugs, such as estrogens, testosterone, clonidine and nitro-glycerine. Transdermal delivery provides a leading edge over injectable and(More)
Objective: Lipases represent an important group of hydrolytic proteins. These enzymes find numerous applications in the industrial sector to provide regioselective molecules of commercial interest. The present investigation was carried out to isolate and identify a bacterium that can quickly produce this enzyme from very simple and cost effective nutrient(More)
A communication system has a great demand for increasing the high broadband limit and to achieve a much better network coverage. Radio over Fiber holds a great potential to yield a better efficiency for the present wireless broadband communication systems. Radio over fiber cater to an untethered access to the systems for applications like low line losses,(More)
Nowadays companies operate in a difficult environment: the dynamics of innovations increase and product life cycles become shorter. Therefore, companies need new methods for the planning of manufacturing systems. One promising approach in this context is digital factory/virtual production—the modeling and analysis of computer models of the planned factory(More)
Aging is a process in which continuous failure of maintenance and repair mechanism occurs which are very important for cellular homeostasis. Antioxidants and growth hormone regulators are used to decrease the process of longevity or abnormal aging. Protandim and nuclear factor 2 (Nrf2) are used as super antioxidant to minimise the oxidative stress in the(More)
