Impact of Yogic Practices on Selected Health Related Fitness Parameters of Tribal Students

This study investigated the impact of yogic practices on selected health related fitness parameters of Tribal students. To achieve the purpose of the study, 30 tribal students were selected from N.S.Iya memorial higher secondary school, Ketti Palada, Nilgiris District. The subjects were randomly assigned to two equal groups (n=15). Group- I underwent Yogic practices (YTG) and group - II was acted as a control group (CG). Yoga training was given to the experimental group for 3 days per week (Monday, Wednesday and Friday) for a period of twelve weeks. The control group was not given any sort of training except their routine work. The health related fitness parameters namely muscular strength (measured by one minute sit ups test) and flexibility (measured by sit and reach test) were assessed before and after the training period. The data collected from the subjects was statistically analyzed using‘t’ test to find out significant improvement if any at 0.05 level of confidence. The result of the muscular strength and flexibility speculated significant improvement due to the influence of Yogic practices with the limitations of diet, climate, lifestyle status and previous training. The result of the present study coincides with the findings of the investigation done by different experts in the field of sports sciences. Yogic practices significantly improved muscular strength and flexibility of Tribal students

EXPERIMENTAL INVESTIGATION AND NEURAL NETWORK PREDICTION OF THE PERFORMANCE OF A MIXED MODE SOLAR DRYER FOR COCONUT

The shelf life of agricultural food products may be enhanced by reducing their moisture contents, by means of a drying process. The present work aims at drying coconut yielding copra. This paper presents the design, analysis of a mixed mode solar dryer for food preservation and energy saving. In the mixed mode solar dryer, the drying cabinet absorbs solar energy directly through the transparent roof and during the same time the heated air from a solar collector is passed through a tray. Various measurements like solar radiation, mass flow rate, and moisture content and relative humidity have been observed. From previous literature four different models (Newton, Page, Henderson & Pabis and Wang & Singh) are chosen for testing the performance of mixed mode solar dryer. Selected models are evaluated by using EMD, ERMS, R2 and ðœ’2 and it is concluded that page model is more suitable for the fabricated cabinet solar dryer at air flow rate 0.009Kg/s based on the experimental analysis. The direct radiant solar energy and a convective hot air stream dry the products, resulting in longer life for the products which are also free from impurities. The experimental results are utilized to evolve a suitable mathematical model, among the different models that are chosen, for copra. This will help in designing suitable dryers for actual users. Also, a multilayer neural network approach has been used to predict the performance of a mixed mode solar dryer for drying coconut. The simulation of neural network is based on the feed forward back propagation algorithm

Size-distribution of submicron aerosol particles over the Indian Ocean during IFP-99 of INDOEX

Measurements of the size-distribution of submicron aerosol particles of diameter from 0.003 to 1 μm are made over the Indian Ocean during the IFP-99 of the Indian Ocean Experiment (INDOEX). Measurements are made during the onward journey from Goa to Port Louis, Mauritius from 20 January to 11 February 1999 onboard ORV Sagar Kanya and during the return journey from Port Louis to Male from 22 February to 1 March 1999 onboard Ronald H. Brown. Observations show large concentrations in the range of 2-6 × 103 particles/cm3 over the Indian Ocean in the northern hemisphere and these drop down to about 500 particles/cm3 in the southern hemisphere. However, the aerosol concentrations show a peak of about 3 × 103 particles/cm3 at 13°S. In the northern hemisphere, the concentration of particles of diameter < 0.0749 μm increases from 14°N to 1°N and then steeply falls. On the other hand, the concentration of particles of diameter > 0.0749 μm keeps decreasing up to 6°S. Size distributions of particles at open sea in the northern hemisphere show a maximum at 0.133 μm and minimum at 0.0422 μm and are generally openended at the smaller size end. The size-distributions of particles are sometimes relatively flat from 0.0133 to 0.237 μm when the particle concentrations are low in the southern hemisphere. The transport and accumulation of aerosol particles in the Inter-Tropical Convergence Zone is discussed. The relative abundance of large versus small particles is examined with respect to the variation of surface atmospheric pressure along the route

Airborne measurements of submicron aerosols across the coastline at Bhubaneswar during ICARB

Airborne measurements of the number concentration and size distribution of aerosols from 13 to 700 nm diameter have been made at four vertical levels across a coastline at Bhubaneswar (20°25'N, 85°83'E) during the Integrated Campaign for Aerosols, gases and Radiation Budget (ICARB) programme conducted in March-April 2006. The measurements made during the constant-level flights at 0.5, 1, 2 and 3 km altitude levels extend ~100 km over land and ~150km over ocean. Aerosol number concentrations vary from 2200 to 4500 cm-3 at 0.5 km level but are almost constant at ~6000 cm-3 and ~800 cm-3 at 2 and 3 km levels, respectively. At 1km level, aerosol number concentration shows a peak of 18,070 cm-3 around the coastline. Most of the aerosol size distribution curves at 0.5 km and 1 km levels are monomodal with a maxima at 110 nm diameter which shifts to 70 nm diameter at 2 and 3 km levels. However, at the peak at 1 km level, number concentration has a bimodal distribution with an additional maximum appearing in nucleation mode. It is proposed that this maxima in nucleation mode at 1 km level may be due to the formation and transport of new particles from coastal regions

1-(Phenyl­sulfon­yl)benzo[1,2:2′,3′]thieno[5′,4′-b]carbazole

The dihedral angle between the fused ring system and the phenyl ring is 83.4 (9)°. The crystal packing is stabilized by C—H⋯π and π–π inter­actions between parallel ring systems [centroid–centroid distances = 3.526 (3), 3.877 (3) and 3.712 (3) Å]

An electron paramagnetic resonance study of Pr_{0.6}Ca_{0.4}MnO_{3} across the charge ordering transition

We report the first electron paramagnetic resonance studies of single crystals and powders of Pr_{0.6}Ca_{0.4}MnO_{3} in the 300-4.2 K range, covering the charge ordering transition at ~ 240 K and antiferromagnetic transition (T_N) at ~ 170 K. The asymmetry parameter for the Dysonian single crystal spectra shows anomalous increase at T_{co}. Below T_{co} the g-value increases continuously, suggesting a gradual strengthening of orbital ordering. The linewidth undergoes a sudden increase at T_{co} and continues to increase down to T_N. The intensity increases as the temperature is decreased till T_{co} due to the renormalization of magnetic susceptibility arising from the build up of ferromagnetic correlations. The value of the exchange constant, J, is estimated to be 154 K.Comment: Uses Revtex3.

In the title molecule, C21H14N2O2, the anthracenyl system is approximately planar [maximum deviation = 0.056 (4) Å] and is oriented at a dihedral angle of 73.6 (1)° with respect to the benzene ring. An intra­molecular C—H⋯N hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by C—H⋯π and π–π inter­actions [centroid–centroid distances of 3.688 (2), 3.656 (1) and 3.716 (2) Å]

COUPLED FIELD ANALYSIS OF PRESSURE VESSEL FURNACE TUBE REDUCER USING FINITE ELEMENT METHOD 1 2 3 4

Abstract The reducer is a device used in boilers to distribute or collect steam water mixture from connected pipes used in the boilers are hollow cylindrical in shape, the connected reducers are more to suit the connected pipes with different diameters. The reducers in a boiler are subjected to the following loads: Internal steam pressure, Axial tensile load due to dead weight of connecting tubes, wind box, casing, buck stay and refractories, Furnace pressure load, Seismic load and Thermal stress due to uneven temperature distribution across the thickness of the reducer. Of these loads the effect of the internal pressure and axial tensile load due to dead load and thermal load on the reducer are considered in this analysis. Between two tubes of different diameters coactivity is ensured by reducer. The dimensions of the reducer are decided based on manufacturing facilities available and constraints. The reducer is checked to comply with the calculations and other requirements of relevant clause of statutory code, Indian Boiler Regulation (IBR). The aim of the analysis is to estimate exact stress and temperature distribution in reducer under actual working condition using Finite Element Method (FEM)
