Review of Remediation of Hg & Cd from Industrial Waste water Using Different Methods
Abstract: Global modernization increasing adverse impact to the aquatic environment mainly due to industrial discharge of waste water. The industrial waste containing nutrients and heavy metals i.e. Hg and Cd leads to eutrophication in water bodies. Various industries released various heavy metals to the natural water bodies. Any kind of heavy metals released to the environment is carcinogenic or toxic in nature. So removal of heavy metals from waste water is …

Soil : Our Need
Abstract: Helpful soil microorganisms exist in soils, so these species are nature's unsung heroes. They develop potential interaction with plants, among other things, to shield them from harm and give plants with nourishment. Dust, chemicals, as well as other unwanted substances from surface water by soil. Which is because many of the healthiest sources of water are underground. Natural methods, like soil uptake, chemical filtration, and the nutrition cycle, according to …

Mathematical models in Predictive microbiology for food safety
Abstract: The study of predictive microbiology is predicated on the notion that populations of microorganisms react in a predictable manner to the conditions of their environment and that historical observations can be used to predict how populations will react in the future by looking at environments in terms of the dominant limitations they present. Predictive microbiology is a relatively new branch of the field of microbiology that has recently gained significant …

Electrodes at commercial forefronts
Abstract: Electrodes at commercial forefronts describe self sustenance approaches in place of traditional cent percent dependence on fissile fuels. Application of solid oxide fuel cells in developed multi-electrode systems have employed in cases of power shortages at nano-material designs. Nano-materials have large surface area but introduced problems such as poor electrode packing densities, high electrolyte reactivity, and expensive synthesis procedures. Thermal stress assisted electrolytic decomposition has motivated use of high temperature …

Solubility Enhancement of Theophylline Drug Using Mixed Solvency Approach
Abstract: “Solubility enhancement” is one of the difficult tasks that have become a great challenge in formulation development of orally administered drugs having poor aqueous solubility. Poor aqueous solubility of drugs creates significant problems in producing formulations of sufficiently high bioavailability, thereby preventing the effective usage of these drugs. With the introduction of the concept of “mixed-solvency,” it is feasible to increase the solubility of poorly water-soluble drugs in aqueous solutions …

Optimization of Reaction Parameters for the Production of Fatty Acids from Rice Bran Oil
Abstract: Fatty acids are usually produced industrially by the hydrolysis of triglycerides and glycerol as by product. In this reaction, 1 molecule of fat/oil will react with 3 molecules of water. The hydrolysis can be done by with and without catalyst. The catalyst process has some inherent problems. To get better quality of fatty acids and high yield the most of the industries preferring the hydrolysis without catalyst. The present study …
