An Improved Scheduling Algorithm for Traveling Tournament Problem with Maximum Trip Length Two
No full textThe Traveling Tournament Problem(TTP) is a combinatorial optimization problem where we have to give a scheduling algorithm which minimizes the total distance traveled by all the participating teams of a double round-robin tournament maintaining given constraints. Most of the instances of this problem with more than ten teams are still unsolved. By definition of the problem the number of teams participating has to be even. There are different variants of this problem depending on the constraints. In this problem, we consider the case where number of teams is a multiple of four and a team can not play more than two consecutive home or away matches. Our scheduling algorithm gives better result than the existing best result for number of teams less or equal to 32
Prevalence and Factors Associated with Overweight/Obesity in Adolescent School Girls: A Cross-Sectional Study in Kolkata, India
No full textOverweight and obesity in adolescent girls are considered a leading global public health issues in recent times. There is a need to evaluate the potential socioeconomic and behavioural factors behind adolescents’ overweight and obesity in different environmental settings. The present study aims to understand the prevalence of overweight and obesity among urban adolescent school girls and to determine the association between selected socioeconomic and behavioural factors and overweight/obesity. This is a cross-sectional study using a multistage stratified cluster sampling with a sample size of 1041 adolescent girls aged 10 to 18 years from schools of Kolkata, India. Overall prevalence of overweight and obesity were 18.9% and 23.7%, respectively. The prevalence of overweight and obesity was higher among those adolescent girls whose parents had completed higher education (49.5%) and had higher monthly per capita household expenditure (48.4%). Stepwise binary logistic regression analysis confirmed that the probability of being overweight/ obese tended to be in adolescents who slept less than 7 hours per day (pem>p=0.002), taken medicines three months before the survey (p=0.008), and watched television and mobile phones for more than 1 hour a day (p=0.039). Rapid change in modern lifestyles is seemingly decreasing sleep duration in adolescents with subsequent negative impact on their health

No full textA rapid increase in electric power consumption is witnessed, there is a demand for the uninterrupted power supply. Newer generation units are being built with the increased installed power. The available transmission lines are reaching critical limits of ampacity and sag; hence there exists an intricacy in finding corridors particularly in densely populated cities to construct new overhead lines in many industrialized countries including India. Most of the times, it becomes impossible to obtain a right of way for the new transmission lines; hence, present circumstances demand the use of available lines representing a cheaper solution than going in for an underground transmission. Increasing the transmission capacity of overhead lines using high temperature low sag (HTLS) conductors, replacing original ACSR conductors with approximately the same diameter is one of the techniques. HTLS conductors are capable of withstanding high-temperature, continuous operation above 200 degrees C without loss of tensile strength or increase in sag. In the present work, a computer program is developed in accordance with IEEE Std.738 to estimate the current and temperature distribution for various HTLS conductors and a graphical user interface has been developed to optimize the selection of various hardware accessories used for HTLS conductors. A novel experimental facility has been built for the present study. Results obtained for both simulation and experimental investigations are analyzed and presented. An attempt has also been made to study the effect of magnetic fields due to higher currents in the conductors

No full textPresently there is a continuous demand for the electric power consumption across the globe, however with the existing distribution lines are reaching critical limits of ampacity and sag, it has become difficult in finding corridors to construct new overhead lines in many industrialized countries including India. Replacing the existing ACSR conductors with high temperature high current low sag (HTLS) conductors almost of the same diameter is one of the recent methods. The present work a parametric study is conducted for steady state surface temperature, thermal time constant, change of emissivity, absorptivity etc for various ACSR and HTLS conductors using the developed computer code which is in accordance with IEEE Std. 738. Some experimental study is also conducted and the results obtained are presented. (C) 2016 The Authors. Published by Elsevier Ltd
X Chromatin inactivation in Menopause: A study on Hindu caste Bengalee population
No full textBackground: Menopause being a physiologic event and eventually the prime time to perform risk assessment of chronic diseases and initiate preventive health measures. Previous studies reported, later menopause is independently associated to increased risk of breast and endometrial cancer. The menopausal status is determined and influenced by intrinsic factors. Majority of the studies on menopause from Indian context, especially on Bengalee Hindu Caste population confined to socio demographic issues, attitudes, problems and quality of life. However, relatively little work is attempted to unravel the complex interplay of genetics and epigenetic mechanisms, the effect on menopause. In this background it seems to be an urgent need to understand menopause status objectively, to approach the interplay of genetics and epigenetic mechanisms of menopausal status by X chromatin inactivation.Aims and Objective: Best of the knowledge it is the first attempt to evaluate the prevalence of X chromatin inactivation in menopausal women among Bengalee Hindu Caste population.Materials and Methods: Sex chromatin inactivation was evaluated from 100 each pre and post menopausal women from the buccal smear of each individuals. After fixation and staining of altogether 20000 (twenty thousand) cells were scanned from the Bengalee Hindu Caste for a comparison of menopausal women and their menarcheal counterparts.Results: Result demonstrated significantly decreased (P<0.001) prevalence of X chromatin inactivation sites among the menopausal females in comparison to their menarcheal women counterpart.Conclusion: The present study vindicated possible association between the presence of sex hormone receptors and the prevalence of sex chromatin and also envisaged the role of X chromatin inactivation for early prognosis of menopause.Asian Journal of Medical Sciences Vol.9(3) 2018 41-45</jats:p
