The aim of the present study was to analysis the differences in anthropometric characteristics among various playing positions in Hockey. In Hockey the players were classified according to their playing position. These playing position were attackers, Midfielders and Defenders. Fifteen players each from attackers (A), Midfielders (B) and Defenders (D) were chosen as subject for this study. The data were collected during South Zone Inter- University Hockey Tournament held at Bharathiar University Coimbatore, Tamil Nadu, India. The subjects were randomly selected from various provinces. Body height, body mass, arm span, arm length, palm length, palm span, triceps, subscapular, Biceps, Iliac crest, lateral abdomen, Abdomen, Front thigh, Medial calf, Elbow diameter, knee diameter, arm girth relax, arm girth flex, fore arm girth, waist girth, gluteus girth, thigh girth and calf girth were selected as a anthropometrical variables for this study. The collected data was statistically analysed by using analysis of variance. The scheffe’s test was used as a post hoc test to determine which of the paired mean differ significantly. The result reveals that there was significant differences between the playing position on the following variables namely body height, body weight, palm span, palm length, sub scapularis, triceps, biceps, lateral abdomen, abdomen, iliac crest, front thigh, mid calf, elbow diameter, arm girth relax. Arm girth flex, fore arm girth, waist girth, gluteus girth, thigh girth, & calf girth is high in Midfielders. Defenders have greater value in the arm length, arm span and knee diameter followed by mid fielders and attackers.

In adaptive sliding mode observer is designed for momentum biased satellites attitude tracking control with unmeasurable yaw attitude information [1]. A higher-order sliding-mode observer is proposed in nonlinear longitudinal dynamic equations. The observable states can be estimated exactly and the unobservable ones will be identified asymptotically [2]. Firstly, the system is decomposed into two low dimensional subsystems by a restricted system equivalent decomposed method. Secondly, the sliding mode controller is designed based on the restricted equivalent subsystems. The quadratic performance index optimal control technique is introduced to design the optimal sliding mode [3]. The stability of the nonlinear sliding mode is analysed. Simulation results are employed to test the effect of the proposed design algorithm [4]. A decentralized adaptive fuzzy approximation design to achieve attitude tracking control for formation flying in the presence of external disturbances and actuator faults [5].

In this paper we have extended generalized finite Hankel transform in [2] with the use of Zemanian’s technique related to the transformations arising from orthonormal series expansions (see [6]). Inversion formula, characterization theorem and application of differential operator in solving certain type of differential equations have been established.

The antidiabetic drug pioglitazone is hydrophobic and having dissolution rate limited bioavailability. Several attempts were made to enhance its dissolution rate. In this investigation the two well known techniques viz., microcapsules and compression coating originally designed for sustained drug delivery were used for enhancing the dissolution rate of Pioglitazone. The polymer eudragit E100 was reported as a taste masking material for bitter drugs. However this research work is aimed to exploit eudragit E100 as dissolution enhancer by virtue of its acid solubility. The polymer was incorporated as a carrier for preparation of solid dispersion, coating material in microcapsules and compression coated tablets. The prepared formulations were evaluated for various parameters including the compatibility studies with IR spectra and drug dissolution studies. The drug Pioglitazone was found to be compatible with eudragit and dissolution rate was also increased in presence of the polymer. The dissolution rate was increased in presence of the polymer and dependent on the technique employed. High dissolution rate of Pioglitazone was observed from the tablets coated with the polymer eudragit E100.

The main aim of this study is analysis of job satisfaction and emotional intelligence between staffs in private banks in Kermanshah. This study is according to descriptive analysis and reaching branch and information gathering tools is questionnaire and for assessing job satisfaction we use briefed and worth 18 questionnaires and for assessing emotional intelligence we use Mayer and Salvoy 27questionaries. Sample population volume 270 subjects from staff's private banks in Kermanshah and according to sampling random way some of them had been chosen a stoical population and finally we collected 92 questions airs. For determining normality of data we use Kolmogorov -Simonov test and results of tests confirm normality of data so meaningful relationship between them had approved.

Turbo codes are one of the most powerful error correcting codes. In this paper focus is made on Bit Error Rate (BER) performance analysis of MAP, Log MAP and Max Log MAP turbo decoding algorithms in wireless AWGN channels. The research is investigated in several aspects to evaluate the performance of turbo codes in AWGN channel with different Signal to Noise Ratio (SNR), different generator polynomials and for different constraint lengths. The simulation results give some demonstrations that are valuable for the applications of turbo codes in AWGN channel with different SNRs.

In this paper, properties of fuzzy extremally disconnected spaces and fuzzy submaximal spaces are discussed.

An exact solution of unsteady flow past a parabolic starting motion of an infinite vertical plate with variable temperature and uniform mass diffusion, in the presence of homogeneous chemical reaction of first order has been studied. The plate temperature is raised linearly with time and the concentration level near the plate is raised uniformly. The solutions for the velocity, temperature and concentration fields are solved using Laplace-transform technique. The effect of velocity profiles are studied for the physical parameters like chemical reaction parameter, thermal Grashof number, mass Grashof number, Schmidt number and time. It is observed that the velocity increases with increasing values the thermal Grashof number or mass Grashof number. The trend is just reversed with respect to the chemical reaction parameter or the Schmidt number.

Vegetation and soil management needs a holistic approach which is already devised into the state and transition model and other ecological, while abolished, models. But these models have some disadvantages and limitations that disable them for managerial purposes. Here in this paper, using a case study to prove the idea, another complementary state and transition model is introduced. This model is more comprehensive and gives managers a more wide view into ecological processes undergoing in a site.

The green microalga strain, Botryococcus braunii Kützing, was provided by the Culture Collection of Algae at the University of Texas (Austin, USA). The effects of nitrogen and temperature on growth and lipid production were studied for 18 days. Cultures of B. braunii were incubated in five different nitrogen concentrations: 1 g L-1 (group 1), 0.5 g L-1(group 2), 0.25 g L-1 (group 3), 0.125 g L-1(group 4) and free nitrogen (group 5). The highest biomass concentration (0.564±0.200 g L-1) and lipid content (33.31±0.014%) were obtained by cultivation with an initial nitrogen concentration of 0.50 g L-1 in these experiments. In free nitrogen, the maximum lipid content was 56.31±0.026% of dry weight, while the biomass concentration was 0.270±0.063 g L-1 at 20 °C. The density of the biodiesel obtained from B. braunii was calculated as 0.8263 kg.L-1, its viscosity as 4.97 mm2.s-1 at 40 °C and its flash point as 109 °C. According to these results, nitrogen-starved Botryococcus braunii increased the production of lipids and could be made more suitable for biodiesel production. This study suggests that it is possible to utilize Botryococcus braunii for biodiesel production.
