Opis:
Purpose: This study was done to ascertain gender dif ferences in trained swimmers between their Critical S wim Speed (CSS). Certain metabolic responses, imme diately after 400 meters free style swimming (FSS), w ith maximum effort, were also studied. Methods: The analysis was conducted in trained swi mmers between 12- 18 years age. Height, weight, bod y fat quantity were estimated using standard techniqu es. CSS was measured for each swimmer. Blood samp les were taken within two minutes of 400 meters FSS, with maximum efforts. The blood creatinine, lactic ac id, serum calcium, serum urea and serum urea nitroge n were estimated using standard laboratory methods. Results: With the maximal effort of 400 meters FSS, values of hematological variables for both sexes were found to increase many folds than reference values. Si gnificant (p<0.05) gender differences were observed in CSS and blood creatinine. The positive significant (p<0.05) correlation was found between CSS and heig ht in the swimmers. For trained male swimmers signif icant positive correlations among CSS, blood urea an d serum urea nitrogen were found. Conclusions: This study reflects metabolic status of b oth trained male and female swimmers, after their full efforts. Besides blood creatinine no significant differe nces were observed in them. So it may conclude that e ffective physical training minimizes the metabolic de mands during their full efforts and gender differences could be overcome.

Opis:
The study is based on the avian community observed in the region. In total, 524 individuals, 27 genera and 35 species of birds belonging to 21 families have been recorded. Among them, the family Charadriidae with 15.08% incidence is the most frequent; immediately followed by the family Scolopacidae (11.26% of occurence). The highest observed species richness has been observed in case of the family Ardeidae. Little Ringed Plover (Charadrius dubius) is the most abundant avian species observed. The community consists of 40% Resident; 40% Resident-migrant and 20% Migrant bird species. It was observed that the concerned community shows a considerable diversity and a corresponding low value of dominance. In the feeding guild analysis, the Insectivore and the Aquatic invertebrate-feeder guilds have the most number of recorded avian species. The feeding guild affiliations also points out that the overall community is fairly rich in its composition as it houses bird species belonging to various feeding guilds.

Opis:
Evolution of manufacturing technology has been a definitive indicator of human society’s development. From the wheels that started the spree to the world of machines that have revolutionized the manufacturing processes, manufacturing tools have been indicative of eras of development. In this paper, we have focused on the branch of engineering that deals with manufacturing - specifically its structure in India. In this study we investigate some premier government institutes with respect to Manufacturing Engineering Education. We have also included the technical education model at different education level.

Opis:
This paper considers the problem of estimating the population mean Y of the study variate y using information on auxiliary variate x. We have suggested a generalized version of Bahl and Tuteja (1991) estimator and its properties are studied. It is found that asymptotic optimum estimator (AOE) in the proposed generalized version of Bahl and Tuteja (1991) estimator is biased. In some applications, biasedness of an estimator is disadvantageous. So applying the procedure of Singh and Singh (1993) we derived an almost unbiased version of AOE. A numerical illustration is given in the support of the present study.

Opis:
This paper advocates the improved separate ratio exponential estimator for population mean of the study variable y using the information based on auxiliary variable x in stratified random sampling. The bias and mean squared error (MSE) of the suggested estimator have been obtained upto the first degree of approximation. The theoretical and numerical comparisons are carried out to show the efficiency of the suggested estimator over sample mean estimator, usual separate ratio and separate product estimator.

Opis:
Bone quality varies from one patient to another extensively; also, Young’s modulus may deviate up to 40% of normal bone quality, which results into alteration of bone stiffness immensely. The prime goal of this study is to design the optimum dental implant considering the mechanical response at bone implant interfaces for a patient with specific bone quality. Method. 3D model of mandible and natural molar tooth were prepared from CT scan data while, dental implants were modelled using different diameter, length and porosity and FE analysis was carried out. Based on the variation in bone density, five different bone qualities were considered. First, failure analysis of implants, under maximum biting force of 250N had been performed; next, the implants, those survived were selected for observing the mechanical response at bone implant interfaces under common chewing load of 120N. Result. Maximum Von Mises stress did not surpass the yield strength of the implant material (TiAl4V). However, factor of safety of 1.5 was considered and all but two dental implants survived the design stress or allowable stress. Under 120N load, distribution of Von Mises stress and strain at the bone-implant interface corresponding to the rest of the implants for five bone conditions were obtained and enlisted. Conclusion. Implants, exhibiting interface strain within 1500-3000 microstrain range show the best bone remodelling and osseointegration. So, implant models, having this range of interface strains were selected corresponding to the particular bone quality. A set of optimum dental implants for each of the bone qualities were predicted.
