A Comparative Study of Neem Oil and Mahogany Oil as Corrosion Inhibitors for Mild Steel Exposed to Hydrochloric Acid
Abstract: Corrosion is essentially an oxidation process, wherein the oxidizing agent itself undergoes reduction due to the influence of corrosion agents like salt, air, or moisture. Metals and their alloys naturally tend to react spontaneously with their surroundings, leading to a detrimental impact on their mechanical and physical properties. This project aimed to evaluate the effectiveness of two different oils, namely neem oil and mahogany oil, as agents to prevent acid …

Understanding of optical power in semiconductor based SOI Structure at the signal 1550 nm
Abstract: A silicon-on-insulator (SOI) structure consists of a single crystalline silicon layer separated from the bulk substrate by a thin insulator layer. The insulator in SOI wafers is usually always a thermal silicon oxide (SiO2) layer, with a silicon wafer as the substrate. The silicon sheet can be very thin (50 nm for fully depleted transistors) or tens of micrometres thick, depending on the application. Similarly, the thickness of buried oxide …

Lipid Peroxidation in Postoperative Cases of Breast Carcinoma (Grade III)
Abstract: Breast cancer represents significant problem in the world. Oxidative modification of lipids is catalyzed by reactive oxygen species (ROS) which is known as lipid peroxidation (LPO); this changes the fluidity, permeability of membrane, cellular metabolic functions and causes derangement. Malondialdehyde (MDA) is a major end product and an index of LPO which crosslinks DNA, protein and nucleotides on the same and opposite strands. There are reports that LPO increased in …

Arsenic as a Cause of Cancer
Abstract: Inorganic Arsenic (iAs) is a pervasive and ubiquitous environmental toxin that has created world-wide human health problems. Populations exposed to high concentrations of arsenic-contaminated drinking water suffer serious health consequences ranging from acute toxicities to development of malignancies, including alarming cancer incidence and death rates. Epidemiologic studies have shown a relationship between chronic arsenic exposure and disease of the skin, lung, urinary bladder, and conceivably liver, kidney, and prostate in …

Differential Response by Rotenone on Human Trabecular Meshwork and HeLa Cell Lines
Abstract: Cellular response towards a particular stress condition is dependent on a number of factors including genetic makeup, microenvironmental factors, nutrient availability etc. Cells under same stress condition respond differentially and may exhibit pro-apoptotic or anti-apoptotic behavior. Two quite different cell lines—the cancerous cells of HeLa and the Human Trabecular Meshwork (HTM) cell line with very different microenvironmental requirements behave very differently towards oxidative insult due to rotenone. Study of their …
