We have synthesis manganese sulfide nano-crystalline (n-MnS) powder using manganese acetate and thiourea, trisodium citrate, from chemical route at different pH. The formation of MnS has been confirmed with help of infrared (IR) spectroscopy by observing bands corresponding to the multi phonon absorption. We have also observed the IR bands at 1403 and 1560 cm-1 due to symmetric and asymmetric stretching of COO of the capped sodium citrate at MnS nano-crystalline particles. The Size of crystal is determined as 3-5 nm with the help of X-ray diffraction. We also deposited the thin film of MnS on glass substrate from the solution using self- aggregation approach. The film thickness is measured as 366 nm with profile meter. The optical band gap is calculated as 3.1-3.5 eV. Its value is found to depend on pH. We also measured dark and photo- conductivity at different temperatures.

Match analysis is a major subject among coaches, team managers and sport scientists and it is gaining an increasing relevance day by day. Information and the relevant data processing are the key factors while referring to this aspect of the sports training methodology. In India Kabaddi is a major sport, which is played all over the India. The present study attempts to design and develop a digital match analysis system for Kabaddi matches. The data were collected during South Zone Inter-University Kabaddi tournament for men 2010-2011 held at Karnataka University, Dharward was used for analysis. After getting various inputs from experts and literature, the investigators had designed and developed a digital match analysis system. A survey was conducted among 15 Coaches, Physical Educators, Players and officials which revealed that the 16 factors which are essential for analysing the performance of the team & individual. This study was a preliminary work and needs testing at all levels. It was also concluded that the result of the study may be very much helpful to the Physical Educationists and Coaches in enhancing the performance level of the Kabaddi players. The outcome of the study may act as a tool to analyse the team & individual performance in the game of Kabaddi.

A simple, precise, accurate and rapid high-performance thin-layer chromatographic method has been developed and validated for the estimation of Montelukast sodium and Levocetrizine Hydrochloride simultaneously in combined dosage forms. The stationary phase used was precoated silica gel 60F 254. The mobile phase used was a mixture of Chloroform: Benzene: Methanol: Toluene (5:7.2:1:0.2 v/v/v/v). The detection of spots was carried out at 286 nm. The method was validated in terms of linearity, accuracy, precision and specificity. The calibration curve was found to be linear between 500-1500 ng spot-1 for Montelukast sodium 1000-5000 ng spot-1 for Levocetrizine Hydrochloride. The limit of detection and the limit of quantification for Montelukast sodium were found to be 170 ng/spot and 570 ng/spot respectively, for Levocetrizine Hydrochloride and Levocetrizine Hydrochloride, 20 ng/spot and 70 ng/spot respectively. The proposed method can be successfully used to determine the drug content of marketed formulation.

In today’s era manipulation of image has become a simple task because of advanced photo editing software packages as well as the capturing devices having high resolution. Verification of the truthfulness of images as well as detection of tampering without having the extra prior knowledge of image content is a significant research field. An attempt is made to review the recent developments in digital image forgery detection. Passive methods do not require prior information about the image. In this paper first various image forgery detection techniques are classified and then its general structure is developed. Passive image authentication overview is presented and the existing passive forgery detection techniques are reviewed. The present status of image forgery detection technique is discussed along with a recommendation for future research. In this paper the effort has been made for finding the best forgery detection algorithm such as SIFT for identifying the manipulated region. The common scenario has been considered where the goal is to remove the features. The attacks conceived so far against SIFT-based forensic techniques implicitly assume that all SIFT keypoints have similar properties. It is better to use SIFT classification scheme based on the gray scale histogram of the neighborhood of SIFT keypoints.

The present paper entitled “Dominant Mothers” concentrates on how motherhood become a dominant feelings and it made them to decide the destiny of their daughters. The portrayal of mothers as dominant ones in the novels of Difficult Daughters is realistic and also shows how mother characters voice their welfare oriented attitudinal behaviours towards their daughters.

Dufour effect on unsteady free convection MHD flow past a moving vertical plate through porous medium with variable temperature and constant mass diffusion is studied here. The Laplace transform technique has been used to find the solutions for the velocity, temperature and concentration. The results obtained are discussed with the help of graphs drawn for different parameters like thermal Grashof number, mass Grashof number, Prandtl number, permeability parameter, the Hartmann number, Schmidt number, Dufour number, time and inclination of magnetic field. The numerical values of Skin-friction have been tabulated.

The concepts traditional marketing, e-commerce, e-business, e-Marketing plan and interactive marketing have been discussed. Advantages and disadvantages of e-marketing have been discussed briefly.

Children are like white cloth that parents need to make, to become a nation's next generation. Early childhood education is crucial in determining the direction of their lives in the future. However, many do not know how to make children in the right form. The study aims to expose the society to the early form of early childhood education based on early childhood education theory of Islam and the West. The concept of early childhood education is divided into two stages. The first stage starts from 0 to 3 years, and the second level starts from 3 to 6 years. There are three theories that need to be incorporated to formulate the curriculum for early childhood education namely behavioral theory, theoretical behavioral theory and constructivist theory. This study is a form of information gathering through sources of books and journals related to early childhood education in Malaysia. The summary of the literature review finds that early childhood education needs to be emphasized by parents who are the first teachers at 0 to 3 years with the support of preschoolers from 3 to 6 years so that the generation of brilliant generations can begin early on.

The effect of some natural product extracts (Punica Granatum Peel PG, Solenostemma Argel SA, Olibanum O, Datura Seeds DS and Datura Leaves DL) on the corrosion behavior of mild steel in 1.0M HCl was studied by electrochemical techniques (open–circuit potential, linear polarization resistance and Tafel plots polarization). It is clear, these extracts give inhibition in both anodic and cathodic slopes in Tafel polarization, that indicate these inhibitors used as mixed-type inhibitor. The thermodynamic adsorption isotherm was studied and falls into Langmuir isotherm indicating physisorption isotherm behavior. In addition, the surface morphology of mild steel samples without and with the inhibitors was examined using scanning electron microscopy.

The studies improved that the temperature has an impact on the PV as well as the solar radiation. In this article, we try to find the relation between the tilt angle and the temperature resulted. The practical experiments were conducted in the lab using a solar cell simulator to find this relation and to evaluate the impact of this relation on the panel's outcomes. The results indicated that the PV module temperature increases as a result from the increase of the solar intensity with increasing the tilt angle. The increase in the PV module temperature caused an increase in the voltage, a decrease in the current, and finally, increased the power
