 Abstract

Bioelectret of Teflon sheet was prepared for the polarizing time of 5, 6, and 7 hr with a field strength of 700, 800, and 1000 kV/m at room temperature (300 K). The thermally stimulated discharge current (TSDC) spectra of Teflon were complex and were composed of two peaks of opposite polarity. This suggests that there are two separate mechanisms for the release of TSDC. In addition, TSDC spectra of non-polarized Teflon sheets give triple reversal from positive to negative, negative to positive, and again from positive to negative.

 Abstract

environmental destruction has become the foremost important issue within the recent years. Like manufacturing of cement produce gas whereas the assembly of aggregates adds dust to the environment. Production of coarse aggregates also impact the geology of the globe from they were extracted. A step taken during this direction is that the use of waste products along with or in replacement of cement. Use of more and more environmentally friendly materials in any industry normally and construction study particularly, is of paramount importance. additionally, because the high cost of conventional building materials is that the key factor affecting housing delivery in India. This has necessitated research into alternative materials of Construction. Our present project intends to explore the foremost effective use of stuff like plastic bottle caps waste (PET), and coconut fibre as a constituent of concrete mix replacing the coarse aggregate partially. the foremost objective is to encourage the use of these waste products as construction materials in low-cost housing. during this study, M25 grade of concrete was used and 28 cubes were casted furthermore as their compressive strength and workability was evaluated at 3, 7 and 28 days. The compressive strength and flexural strength of concrete was reduced and increased because the share replacement was varied. The result showed that this concrete is used in concrete construction.

 Abstract

polycystic ovary syndrome is one of the most common endocrine disorders that affect approximately 6- 20% of women of childbearing age. It is characterized by hyperandrogenism and ovarian dysfunction along with metabolic disorders. Anovulation, hirsutism, obesity, insulin resistance and dyslipidemia may appear as clinical symptoms of polycystic ovary syndrome. There is increased risk of type 2 diabetes and cardiometabolic risk particularly in presence of obesity. Women with polycystic ovary syndrome are at high risk of obesity which further leads to metabolic, psychological and reproductive changes. Drugs like metformin, combined oral contraceptive pills, Spironolactone, play a key role in polycystic ovary syndrome. Polycystic ovary syndrome is not curable, but symptoms can be managed, hence lifestyle modification including proper diet, exercise and behavioral management remain the primary and most effective prevention strategy for polycystic ovary syndrome management.

 Abstract

Rice husk burning and coal-fired power plant emissions cause a slew of environmental issues. The recycling of rice husk ash (RHA) and fly ash (FA) from power plants as reactive materials for the production of sustainable (green) concrete is discussed in this study. The goal of this study is to see how effective RHA and FA replacement ratios are on the fresh and hardened properties of concrete mixtures. For each recyclable material, the replacement ratio from the cement content was 30%. (10% RHA and 20% FA). The drop of freshly poured concrete was determined. The compressive strength and bond strength of hardened concrete were also studied as mechanical properties. The compressive strength was measured at 7 and 28 days. The water permeability of cured concrete was tested as a physical property. When compared to the control combination, test showed that the RHA and FA improved mechanical and physical qualities. The cementitious concentration of 450 kg m3 produced better results than the other materials used. The replacement ratio of 30 percent cement by 10% RHA and 20% fly ash, in particular, resulted in enhanced mechanical characteristics. The water permeability of all combinations reduced as the cementitious concentration increased due to the decrease in air content. As the cementitious content reduced, the water permeability loss ratios improved.

 Abstract

Pamba River is the third largest river in Kerala with a length of about 176 km and a catchment area of about 2,235 sq. km. It is one of the most polluted river system in Kerala. The present study is a pioneering effort to evaluate the feasibility of incorporating Alum coagulant as an effective interim treatment strategy for the removal of coliforms and thereby bringing the process of super chlorination down to low dose chlorination. Pamba river water with high amount of fecal coliform and suspended solids was subjected to chlorination dosage of 10 mg/l for 30 minutes contact time followed by dechlorination with sodium thiosuphate. Super chlorination resulted in the doubling of COD indicating the formation of more recalcitrant highly toxic chlorination derived by-products. The newly formed compounds were extracted and were subjected to structural analysis by FT/IR. The data obtained indicated the presence of Trihalomethane, Haloaceticacid as by-products. The Alum treatment proved that there is remarkable reduction in coliforms at 30 mg/l for 30 minutes contact time without affecting COD. Hence for Pamba River, an integrated alternative treatment strategy using Alum to bring down the toxicity level caused by super chlorination can be deployed.
