Abstract-Aims:In this analysis of body composition such as body weight, BMI, body fat percentage, segmental subcutaneous fat & skeletal muscle percentage (whole body, trunk, legs and arms), resting metabolism, visceral fat level and body age is done by bioelectrical impedance technique and results are interpreted and corresponding instructions for better health improvement is given.Methods: Body composition analysis of teaching and nonteaching staff members of Brijlal Biyani Science College Amravati Maharashtra India using bioelectrical impedance analysis method is done. For ideal weight management and for a more accurate and precise body composition analysis full body sensing technology karada scan body composition monitor -HBF-375 is used. The general principle behind bioelectrical impedance analysis is that two or more conductors are attached to a person's body and a small electric current is sent through the body. The resistance between the conductors provides a measure of body fat between a pair of electrodes, since the resistance to electricity varies between adipose, muscular and skeletal tissue.Result: Interpretation of body composition analysis report of Teaching Staff members (Senior College) shows that overweight person is 70.6 %; that of Junior College is 73.3 %; that of non-teaching staff members (laboratory) is 52.4 % while; that of office is 76.9 %; and that of library is 100 %.Index Terms-Body age, body fat, BMI, RM, skeletal muscle, subcutaneous fat, visceral fat.
Abstract-Aims: Effect of pH on polarographic waves of ascorbic acid were studied by recording polarograms of ascorbic acid solution, between 0 to 400 mV at different pH (0.065 to 9.6) using 0.008% solution of gelatin and 0.05 M potassium hydrogen phthalate buffer (containing 0.25% oxalic acid) as maxima suppressor and supporting electrolyte respectively.Methods: Ascorbic acid is strong reducing agent and produces an anodic wave which shifts with pH. There is no significant change in height of wave with change in pH from 2.25 to 4.85.For determination of ascorbic acid pH 4.0 is chosen. Ascorbic acid present in synthetic sample is determined by calibration, external standard addition and internal standard addition methods. The results obtained are in good agreement with the quoted values.Result: The number of electrons taking part in the reversible reaction is found to be 2. The half-wave potential is found to be independent of the ascorbic acid concentration.Index Terms-Ascorbic acid, calibration method, external standard addition method, internal standard addition method, polarographic determination.
The oxidation of the biologically very important dimethyl sulfoxide system has been the subject of investigations. In present study Dimethyl sulfoxide (DMSO) can be oxidized to dimethyl sulfone by anodic electrolysis at a rotating platinum electrode. The polarographic method has been used to study qualitatively the effect of maxima suppressor gelatin, fuchsin, methyl red, thymol blue and supporting electrolyte HCl, CH 3 COOH on oxidation wave of DMSO. Polarographic oxidation of DMSO in 0.1 M HCl, 0.1 M CH 3 COOH solution using optimum concentration of fuchsin, methyl red, thymol blue as surface active substances is followed to determine the DMSO present in synthetic sample by calibration method. Wave analysis indicate the irreversible nature of the oxidation process which involves oxidation of dimethyl sulfoxide to dimethyl sulfone thereby increasing the oxidation state of sulphur from +2 to +4 state.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
