Purpose： To evaluate the efficacy and safety of the glycoside fraction of fenugreek （Trigonellafoenum-graecum） seeds （Fenu-FG） on physiologi- cal parameters related to muscle anabolism, androgenic hormones, and body fat in healthy male subjects during an 8-week resistance training program using a prospective, randomized, double-blind, placebo controlled design. Methods： Sixty healthy male subjects were randomized to ingest capsules of Fenu-FG （1 capsule of 300 rag, twice per day） or the matching placebo at a 1：1 ratio. The subjects participated in a supervised 4-day per week resistance-training program for 8 weeks. The outcome measurements were recorded at recruitment （baseline） and at the end of the treatment （8 weeks）. The efficacy outcome included serum testosterone （total and free） levels, muscle strength and repetitions to failure, metabolic markers for anabolic activity （serum creatinine and blood urea nitrogen）, and % body fat. The standard safety measurements such as adverse events monitoring, vital signs, hematology, biochemistry, and urinalysis were performed. Results： Fenu-FG supplementation demonstrated significant anabolic and androgenic activity as compared with the placebo. Fenu-FG treated subjects showed significant improvements in body fat without a reduction in muscle strength or repetitions to failure. The Fenu-FG supplemen- tation was found to be safe and well-tolerated. Conclusion： Fenu-FG supplementation showed beneficial effects in male subjects during resistance training without any clinical side effects.

Compared with conventional manufacturing methods, the additive manufacturing technique enhances mechanical properties. The present investigation of additive manufacturing technique is focused on delamination studies of Onyx-Glass Fiber Hybrid Polymer Composite(OGFHPC) along with surface roughness properties during machining(drilling) of composites through abrasive water jet machining(AWJM). However, delamination is a major issue during machining of OGFHPC. In order to overcome these drawbacks, the fabrication of OGFHPC was carried out using fused deposition modeling(FDM) technology which is an additive manufacturing method with Mark forged Mark Two 3D-composite printer. The machinability studies were conducted for drilling operation through AWJM process with different abrasive mass flow rates, drilling diameters and traverse speeds. These drilling machinability process parameters were optimized through the design of experiments-Taguchi analysis followed by the analysis of variance(ANOVA) and validated through the Harmony Search Algorithm(HSA), Whale Optimization Algorithm(WOA) and Grey Wolf Optimization Algorithm(GWO). It was observed that minimum delamination and surface roughness of OGFHPC were optimized for AWJM at abrasive mass flow rates(450 g/min), drilling diameters(12 mm) and traverse speed rate(30 mm/min).

This work focuses on the efficiency of the LED acting as the heat sink containing Phase Change Material(PCM). Three different heat sink configurations(H-1, H-2, and H-3) are used in this study. Input power and the number of fins are altered to find their effect on junction temperatures, luminous flux, and thermal resistance. The junction temperature of heat sink H-3 with PCM decreased by 3.1 % when compared with heat sink devoid of PCM at 10 W. The thermal resistance of the heat sink H-3 is reduced by 18.2 % when compared to its counterpart devoid of PCM at 10 W. The luminous flux of the PCM filled heat sink H-3 is found to increase by 12.15 % against the PCM not filled heat sink H-1 at 10 W. The H-3 heat sink with PCM showed superior performance because of the enhanced natural convection and conduction in bulk PCM with fins, and with added high latent heat capacity of PCM.

A network of air quality and weather monitoring stations was established under the System of Air Quality Forecasting and Research（SAFAR） project in Delhi. We report observations of ozone（O_3）, nitrogen oxides（NO_x）, carbon monoxide（CO） and particulate matter（PM_2.5and PM_（10）） before, during and after the Diwali in two consecutive years, i.e., November 2010 and October 2011. The Diwali days are characterised by large firework displays throughout India. The observations show that the background concentrations of particulate matter are between 5 and 10 times the permissible limits in Europe and the United States. During the Diwali-2010, the highest observed PM_（10） and PM_2.5mass concentration is as high as2070 μg/m^3 and 1620 μg/m3, respectively（24 hr mean）, which was about 20 and 27 times to National Ambient Air Quality Standards（NAAQS）. For Diwali-2011, the increase in PM_（10） and PM_2.5mass concentrations was much less with their peaks of 600 and of 390 μg/m^3 respectively, as compared to the background concentrations. Contrary to previous reports,firework display was not found to strongly influence the NO_x, and O_3 mixing ratios, with the increase within the observed variability in the background. CO mixing ratios showed an increase. We show that the large difference in 2010 and 2011 pollutant concentrations is controlled by weather parameters.
