Level of Significance of Various Physical and Chemical Paramete

Nima P. Golhar and P.R .Chaudhari 

  • Abstract

    In present study Physical and Chemical properties of soils and their relationship with electrical conductivity were studied. The soil samples were collected at a depth 20 cm from five different locations of ChalisgaonTehasil region. The soil samples were analyzed for pH, Electrical conductivity, organic carbon, Calcium Carbonate, Nitrogen, Phosphorous, Potassium, Iron, Manganese, Zinc, Copper, Calcium, Magnesium, Bulk density and texture. Electrical Conductivity had high degree positive correlation with silt content and negative significant correlation with sand content. Bulk density showed positive significant correlation with sand soil had higher effect on Electrical Conductivity (EC) and Bulk Density of soils. Electrical conductivity had positive significant correlation with organic carbon, Phosphorous, Potassium, Manganese and Copper.

Amrendra Kumar  and L.K. Mishra

  • Abstract

    Condensate fraction of BEC (N0/N) as a function of (T /Tc 0) were evaluated using non-interacting and interacting models for two different traps and compared with scaling parameter h. Our results indicate that two very different configuration can give rise the same thermodynamic behavior of the condensate corresponding to the scaling parameter h.The evaluation were performed using theoretical formalism developed by F. Dalfavo. et al. Our theoretical results are in good agreement with the other theoretical workers.

An Evaluation of Effective mass (m*/mo) of electron in 2D-electron sys

Ajay Kr. Singh & L.K.Mishra

  • Abstract

    Using two theoretical models (Ando formalism and Vinter formalism) an evaluation of effective mass (m*/mo) of electron as a function of Ns (concentration of electrons) in n-channel inversion layer has been performed. Our theoretical result of (m*/mo) decreases with Ns as per experimental observation. However, the theoretical values evalu

Chaudhari L.M. and Yadav Niteshkumar Krishnakant

  • Abstract

    The linear and mass attenuation coefficient plays an important role in a agriculture, industry, science & technology, basic quality, medicines and forensics etc. We studied the attenuation coefficient of wet and dry wood of Jambul (Syzygiumcumini) by using different gamma ray energies. The results are in the graphical form and it valid the gamma absorption law.

An Evaluation of Visibility of Ramsy Fringes as a Function of M

Gajendra Prasad Gadker and L. K. Mishra.

  • Abstract

    Using the theoretical formalism of K. Goral etal.(2006), we have evaluated the visibility of Ramsy fringes as a function of magnetic field strength Bevolve (G) . We have also evaluated the natural frequency and two-body loss rate constant K2 as a function of same magnetic field strength. Our theoretically evaluated results are in satisfactorily agreement with the experimental data and with other theoretical workers.

Chaudhari L.M. and Rathod S.Z.

  • Abstract

    We measured the linear and mass attenuation coefficient of glucose solution at different concentrations with varying the path length using gamma ray energy 360 keV. The experimental values are in good arrangement and validate absorption law.

Short-Term Temporal Wind Speed Variability: Case Study of Dubbo Village

Ashenafi Abebe, Gelana Amente and Getachew Abebe

  • Abstract

    In this study, short-term temporal variability of wind speed measurement was conducted. Data for day and nighttime wind speeds were collected at 30 minutes intervals for two weeks at Dubbo site. The data were analyzed - statistically by comparing the Weibull parameters. Comparison of daytime and nighttime wind speeds indicated higher average daytime wind speed than that of the night time with the average exceeding the 24 hour average by nearly 20%. Comparison of daytime wind speeds of five data points with 24-hour data points exhibited identical averages with errors of less than 5%.In this study, short-term temporal variability of wind speed measurement was conducted. Data for day and nighttime wind speeds were collected at 30 minutes intervals for two weeks at Dubbo site. The data were analyzed - statistically by comparing the Weibull parameters. Comparison of daytime and nighttime wind speeds indic

A Theoretical Study of Bose Liquid Using Various Semi Empirical Potentials

Uday Narain Singh  and L. K. Mishra

  • Abstract

    We have studied the various semi empirical potentials for interaction of helium atoms in real space and theoretically evaluated the Bogolyubov quasi particle spectrum in Bose liquid. On comparing with inelastic neutron scattering match with the experimental data.

An Evaluation of Collective Mode of One-dimensional Fermi Gas.

Shrawan Kumar and L.K. Mishra

  • Abstract

    Collective mode of one- dimensional Fermi gas has been evaluated over the whole coupling regime from weak coupling (high density) to strong of Alam and Schuck taking attractive δ interaction potential under RPA approximation at zero temperature. We observe that in the weak-coupling limit particle-hole RPA approaches to low momenta and the collective mode in the strong coupling limit reproduces the Bogoliubov mode for the weakly interacting bosons. Our theoretically evaluated results are in good agreement with other theoretical workers.

Effect of He-Ne Laser Radiation on Viscometric Behavior of Human Blood

Shikha Rathore and Basharath Ali 

  • Abstract

    Laser-tissue interaction provides important information about the characteristics and behavior of biological tissues and living cells. Low intensity laser radiations are widely used in clinical practice since last 3 decades. The irradiation of blood is considered as the most efficient method for the bio stimulation of biological cells or living tissues. The purpose of this study is to investigate the effect of Low of viscosity and size of erythrocytes are measured to understand the rheology of blood. These rheological measurements in clinical studies are generally concernedwith the individual components of blood (erythrocytes, leucocytes, platelets and  plasma) which collectively influence blood viscosity. Therefore, it is appropriate to measure the viscosity at three different levels- tissue level (whole blood), cellular level (erythrocytes) and molecular level (plasma). To understand the viscometric blood a

  • Abstract

    An Algorithm is given for direct combinationatorial enumeration ofdistinct skeletons of homopolysubstituted diamantane derivatives having the empirical formula 14 20-q q C H X where X is a non isomerisable ligand and q the degree of substitution. The averaged weights of permutations controlling respectively the chirality and the achirality fittingness are calculated for the parent diamantane in D3d symmetry and then converted into generalized formulas for computing ( ) c A 20,q and ( ) ac A 20,q which are the numbers of chiral and achiral skeletons for any diamantane molecule having a degree of homopolysubstitution 0 £ q £ 20 .

A Review on Solar Air Heater- Energy Analysis of Solar Energy Applications

M.Sakunthala, V.Sridevi, K. Vijay Kumar, N. Harsha & T Kanthi Kiran

  • Abstract

    Solar energy is a clean, abundant and easily available renewable energy. Renewable energy technologies use the sun’s energy and its direct and indirect effects gravitational forces (tides), and the heat of the earth’s core (geothermal) as the resources from which energy is produced.Usage of solar energy in different kinds of systems provides scope for several studies on energy analysis. In the present work, a comprehensive literature review has been carried out on energy analysis of various solar energy systems. In this paper, an analysis of the environmental problems related to the use of conventional sources of energy was presented and the benefits offered by renewable energy systems were outlined.
