Analysis of the Changes in Selected Motor Fitness Components with Concurrent Strength and Plyometric Training

The underlying principle of this study was to assess the effect of eight weeks concurrent strength and plyometric training in enhancing the capability on selected motor fitness components. For the purpose of study, thirty male students of Annamalai University, aged 20 to 22 years took part in the study. Subjects were randomly assigned to either concurrent training (n=15) or control (n=15) group. The training regimen lasted for eight weeks. The selected criterion variables were assessed using standard tests and procedures, prior to and immediately after the training programme. Analysis of covariance was employed to establish degree of significant modification on chosen criterion variables. The findings of the study revealed that eight weeks of concurrent training had an effectiveness of 4.13% on leg strength, 11.81% on strength endurance, 0.40% on speed, and 7.53% on anaerobic power. These findings suggest that the concurrent strength and plyometric training programme has a statistically significant influence in developing the selected criterion variables

Effectiveness of Fartlek Training on Maximum Oxygen Consumption and Resting Pulse Rate

The rationale of this study was to appraise the outcome of the twelve weeks of supervised fartlek training programme on selected physiological parameters. For this purpose twelve male athletes from Dr. S. Ramadoss Arts and Science College, Virudhachalam, in the age group of 20 to 22 years took part in the study. The selected subjects were subjected to twelve weeks of farlek training programme. The selected criterion variables namely: maximum oxygen consumption and resting pulse rate were assessed using standard tests and procedures, prior to and subsequent to the training regimen. The pretest and posttest data collected on criterion variables were statistically examined by applying ‘t’ test to find out the significant difference if any. The analysis of data revealed that twelve weeks of farlek training programme significantly improved maximum oxygen consumption and resting pulse rate. These findings propose that the experimental variable has the significant influence in improving the selected criterion variables

Effect of Fartlek Training on Selected Physiological Parameters among College Male Athletes

The study was proposed to examine the effect of fartlek training on cardiorespiratory endurance, breathe holding time, and pulse rate. To achieve this purpose of the study, thirty male students of SMSS Government Boys Higher Secondary School, Shengottai, were randomly selected, in the age group of fourteen to sixteen years. The selected subjects were divided into two groups. Group I underwent fartlek training programme for twelve weeks and they designated as experimental group. Group II is the control group, which does not undergo any type of systematic training programme during the period of study. The study was restricted to the appraisal of cardiorespiratory endurance, breathe holding time, and resting pulse rate prior to and after experimentation. The pre and post test data of both the groups thus collected were statistically examined by applying analysis of covariance. The outcome of the study demonstrates that statistically significant improvement on cardiorespiratory endurance, while breathe holding time and resting pulse rate were not evolved. It implies that undergoing fartlek training programme confined to this study is worthy enough to enhance cardiorespiratory endurance, but not on breathe holding time and resting pulse rate

Synthesis and Characterization of Polymer (Sulfonated Poly-ether-ether-ketone) Based Nanocomposite (h-boron nitride) Membrane for Hydrogen Storage

The development of light weight and compact hydrogen storage materials is still prerequisite to fuel-cell technology to be fully competitive. The present experimental study reports the hydrogen storage capability of sulfonated poly-ether-ether-ketone (SPEEK)-hexagonal boron nitride (h-BN) (SPEEK-h-BN) nanocomposite membranes. The nanocomposite membranes are prepared by considering various amount of h-BN (0, 1, 3 and 5 wt. %) by phase inversion technique. The degree of sulfonation of the PEEK (SPEEK) is found to be 65% by Proton Nuclear Magnetic Resonance (1H NMR) spectroscopy. Hydrogen adsorption studies have been carried out using a Seiverts-like hydrogenation setup. The membranes are characterized by X-ray Diffractometer (XRD), Micro-Raman spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), CHN-elemental analysis and Thermo Gravimetric Analysis (TGA). It is observed that the SPEEK-5% h-BN membrane performs better than pure SPEEK membrane, has maximum storage capacity of 2.98 wt. % at 150 °C and the adsorbed hydrogen has an average binding energy of 0.38 eV. The TGA study shows the dehydrogenation behavior of hydrogenated SPEEK-h-BN nanocomposite membrane and it is found to be in the temperature range of 214–218 °C for SPEEK-5% h-BN membrane

THEORETICAL ANALYSIS OF A WET COOLING TOWER FOR FRESH WATER FROM PLUME AND ANALYZING AN INDUSTRIAL COOLING TOWER BASED ON RESULTS

A cooling tower is a heat rejection device which rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. The stream of saturated exhaust air leaving the cooling tower called the plume is visible when water vapor it contains condenses in contact with cooler ambient air, like the saturated air in one's breath fogs on a cold day. Under certain conditions, the cooling tower plume may present fogging or icing hazards to its surroundings and gives some environmental problems. To find the solution for this problem a cooling tower has been analysed based on air flow rate through the tower and the cooling load to obtain fresh water yield by utilising plume from cooling tower top. The theoretical analysis gives the values of important parameters Theoretical analysis has been done on wet cooling tower by varying the water flow rate through which affect the performance of a cooling tower such as the cooling range, effectiveness, approach, fresh water yield etc. Then with the conditions of a trials from the analysis, the mass flow rate of water in the cooling tower was scaled up to match the mass flow rate of water in an industrial cooling tower. This helps in obtaining the mass flow rate of the air and fresh water yield through the industrial cooling tower
