The Impact of Hockey Coaches and Team Cohesion on the Performance of Players

The primary objective of the existing paper deals with to examine the relationship of hockey coaches and team cohesion with the performance of field hockey players of Pakistan and their impact on players’ performance. However the secondary objective was to measure the field performance of hockey players on practical measures. The research methodology is based on both descriptive and inferential statistical approaches. The descriptive data was collected in the form of field performance tests (technical skills and fitness capabilities) while the inferential data perceived by players was collected using survey questionnaire. A number of 296 national field hockey players of Pakistan were selected from 14 national departments of field hockey as samples. Descriptive statistics, correlation and multiple regression analysis were employed through SPSS (version 21.0). The results of the field performance tests were found below than average (weaker) in technical skills and fitness capabilities of national field hockey players of Pakistan. However, the findings of the inferential analysis revealed that hockey coaches and team cohesion have positive and significant relationships with the performance of field hockey players. Implications of existing study were also briefed.
The Role of Resource Allocation on Promotion of Intrapreneurship in the Small and Medium Manufacturing Enterprises in Kenya

: Kenya’s manufacturing sector has over the years continued to contribute significantly to the economy’s gross domestic product. Statistics however show that the sector does not perform to its capacity and continues to experience a lag as compared with most of other countries in the world. The manufacturing sector is dominated by the small and medium manufacturing enterprises which by their nature are disadvantaged as is the case with most of other sectors within the SME sector. This is in spite of the important contribution to the country’s economy by the SME sector in general. Studies have shown that firms that practice intrapreneurship whether large or small improve in profitability and growth, as well as maintain the entrepreneurial spirit. Intrapreneurship requires resource allocation by management in the areas that promote it. Resource allocation is a factor in entrepreneurial management which as opposed to administrative management is necessary in advancing the entrepreneurial orientation of a firm. The objective of the study was to find out the role of resource allocation on promotion of intrapreneurship in small and medium manufacturing enterprises in Kenya. The Kenya Association of Manufacturers provided the sampling frame based on the list of the firms registered with it in the year 2015. Descriptive research and correlational designs were used for the study. Correlation analysis, scatter plot and multiple linear regression analysis were used to establish the relationship between the independent and dependent variable.
ADOPTION OF AMMONIATED STRAW TECHNOLOGY BY FARMERS AT SUB-DISTRICT OF DONRI-DONRI, SOPPENG DISTRICT, INDONESIA

The low availability and quality of forage for livestock during the dry season is the main problem faced by the farmers in Indonesia. To alleviate the problems, the use of agricultural by-products that their nutritive value has been improved like ammoniated straw as animal feed is recommended. However, most farmers have poor understanding about ammonisation of straw technology. For this reason, an extension on ammonisation of straw technology was introduced to the farmers. However, after teaching on the ammonisation technology, practice of making ammoniated straw and demonstration on the superiority of using ammoniated rice straw as animal feed had been introduced to the farmers, only one of 20 farmers followed the training who adopted the technology. It is suggested that the purpose of raising the cattle is the main factor determining adoptability of the technology by the farmers.
Percolation and number of phases in the two-dimensional Ising model

We reconsider the percolation approach of Russo, Aizenman, and Higuchi for showing that there exist only two phases in the Ising model on the square lattice. We give a fairly short alternative proof which is only based on stochastic monotonicity and avoids the use of symmetry inequalities originally needed for some background results. Our proof extends to the Ising model on other planar lattices such as the triangular and honeycomb lattice. We can also treat the Ising antiferromagnet in a homogeneous field and the hard-core lattice gas model on Z. © 2000 American Institute of Physics. @S0022-2488 ~00! 00103-1#
Grain opacity and the bulk composition of extrasolar planets. II. An analytical model for the grain opacity in protoplanetary atmospheres

Context. We investigate the grain opacity k_gr in the atmosphere of protoplanets. This is important for the planetary mass-radius relation since k_gr affects the H/He envelope mass of low-mass planets and the critical core mass of giant planets. Aims. The goal of this study is to derive an analytical model for k_gr. Methods. Our model is based on the comparison of the timescales of microphysical processes like grain settling in the Stokes and Epstein regime, growth by Brownian motion coagulation and differential settling, grain evaporation, and grain advection due to envelope contraction. With these timescales we derive the grain size, abundance, and opacity. Results. We find that the main growth process is differential settling. In this regime, k_gr has a simple functional form and is given as 27 Q/8 H rho in the Epstein regime and as 2 Q/H rho for Stokes drag. Grain dynamics lead to a typical radial structure of k_gr with high ISM-like values in the top layers but a strong decrease in the deeper parts where the grain-free molecular opacities take over. Conclusions. In agreement with earlier results we find that k_gr is typically much lower than in the ISM. The equations also show that a higher dust input in the top layer does not strongly increase k_gr with two important implications. First, for a formation of giant planet cores via pebbles, there could be the issue that pebbles increase the grain input high in the atmosphere due to ablation. This could potentially increase k_gr hindering giant planet formation. Our study shows that this adverse effect should not occur. Second, it means that a higher stellar [Fe/H] which presumably leads to a higher surface density of planetesimals only favors giant planet formation without being detrimental to it due to an increased k_gr. This corroborates the result that core accretion explains the increase of the giant planet frequency with [Fe/H].
Antibacterial effect of calcium carbonate nanoparticles on Agrobacterium tumefaciens

Aims: Improvements in nanotechnology in the past decayed has created various opportunities for evaluation of biologic effects such as anti-bacterial effects of nanoparticles. The purpose of this study was to evaluate the antibacterial activity of calcium carbonate nanoparticles on two different bacteria including A grobacterium tumefaciens and Staphylococcus aureu s. Methods: The antibacterial effect of calcium carbonate nanoparticles against mentioned bacteria was evaluated by dilution in agar containing medium and dilution in Broth medium. Each of prepared Broth Media (10 ml) was inoculated with 1 ml of bacterial suspension (10 6 CFU/ml) and incubated. Sampling of culture Media was performed in specific intervals and diluted as 10 -1 , to 10 -6 . Then 100 µl of each sample was transferred to agar plates and was spread carefully and then incubated. Grown colonies were counted and MIC and MBC was determined. Results: Calcium carbonate nanoparticles showed very good antibacterial effect and after 16 hours the bacteria were totally diminished. The lowest and highest MIC concentration of these nanoparticles in solid medium was 31.2 and 125 µg/ml respectively. The MIC of calcium carbonate nanoparticles in Broth Medium was two times more than the MIC concentration in solid medium, while different concentrations of ordinary calcium carbonate not only revealed antibacterial effects but also supported the bacterial growth. Conclusion: Use of calcium carbonate nanoparticles as an anti-microbial agent is recommended in different fields of medicine, food industry and agriculture and can be of importance considering health and economic issues.
Surface and Tropospheric Water Vapor Variability and Decadal Trends at Two Supersites of CO-PDD (Cézeaux and Puy de Dôme) in Central France

We present an analysis of decadal in situ and remote sensing observations of water vapor over the Cézeaux and puy de Dôme, located in central France (45° N, 3° E), in order to document the variability, cycles and trends of surface and tropospheric water vapor at different time scales and the geophysical processes responsible for the water vapor distributions. We use meteorological stations, GPS (Global Positioning System), and lidar datasets, supplemented with three remote sources of water vapor (COSMIC-radio-occultation, ERA-interim-ECMWF numerical model, and AIRS-satellite). The annual cycle of water vapor is clearly established for the two sites of different altitudes and for all types of measurement. Cezeaux and puy de Dôme present almost no diurnal cycle, suggesting that the variability of surface water vapor at this site is more influenced by a sporadic meteorological system than by regular diurnal variations. The lidar dataset shows a greater monthly variability of the vertical distribution than the COSMIC and AIRS satellite products. The Cézeaux site presents a positive trend for the GPS water vapor total column (0.42 ± 0.45 g·kg−1/decade during 2006–2017) and a significant negative trend for the surface water vapor mixing ratio (−0.16 ± 0.09 mm/decade during 2002–2017). The multi-linear regression analysis shows that continental forcings (East Atlantic Pattern and East Atlantic-West Russia Pattern) have a greater influence than oceanic forcing (North Atlantic Oscillation) on the water vapor variations.
An Intriguing Case Of Heroin Induced Delusion Of Parasitosis

Objective: The objective of this case report is to highlight a rare case of delusion of parasitosis induced by heroin abuse. Methods: We report a case of a 44-yearold heroin addict who had the false and unshakeable belief of being infested by the African botfly. As a result of his belief, he resorted to various methods to rid himself of the insect such as picking his skin with a knife and burning his skin with a lighter. Result: He was diagnosed to be suffering from heroin induced psychotic disorder and was successfully treated with the atypical antipsychotic olanzapine. Conclusions: Heroin; an opiate which is not commonly known to cause psychosis was seen to have been the cause of the delusion of parasitosis suffered by our patient.

Testing the forecasting performance of IBEX 35 option-implied risk-neutral densities

The main objective of this paper is to test whether the risk-neutral densities (RNDs) implied in the prices of the future options contract on the Spanish IBEX 35 index accurately predict the distribution of future outcomes of the underlying asset. We estimate RNDs using both parametric and nonparametric procedures. We find that between 1996 and 2003 we cannot reject the hypothesis that the RNDs provide accurate predictions of the distributions of future realisations of the IBEX 35 index at four-week horizon. However, this result is not robust by subperiods. In particular, from October 1996 to February 2000, we find that RNDs are not able to consistently predict the actual realisations of returns. In this period, option prices assign a low risk-neutral probability to large rises compared with realisations. Tests based on the tails of the distribution show that RNDs significantly understate the right tail of the distribution for both the whole period and the first subperiod.
Analysis of microsatellite markers in Ongole breed of cattle

Evaluation of genetic variability was carried out in Ongole cattle using 25 microsatellite markers, recommended by FAO. All the screened loci were polymorphic and a total of 97 alleles were observed across the analyzed loci. The mean number of alleles was found to be 3.88 ±0.25 with a range of 2 to 7. The allele size ranged from 94 to 300 bp. The frequency distribution of microsatellite alleles in the breed was from 0.0119 to 0.9375. The estimated expected heterozygosity value was 0.6079 ±0.04 and the PIC was 0.5584 ±0.04. Microsatellite analysis revealed high allele and gene diversity in the investigated cattle and overall mean F IS value (–0.0615) suggested the excess of heterozygosity in the population. In addition, the high information of the polymorphic loci throw light on the scope for maintaining variation in the population and strategies to formulate conservation and further improvement measures.
Can Lutjanus purpureus (South red snapper) be "legally" considered a red snapper (Lutjanus campechanus)?

Red snappers (Lutjanus purpureus in Brazil and Lutjanus campechanus in USA and Gulf of Mexico) are both under clear effect of overfishing. Because of their high morphological similarity it has already been suggested that they could possibly be considered as a single species. To investigate the degree of similarity and the genetic structure of red snapper populations we constructed a common dataset of partial D-loop mtDNA sequences of L. purpureus from Brazil (Amapa, Para and Maranhao) and L. campechanus from the Atlantic coast of the USA (Florida, Louisiana and Mississippi). Phylogenetic and population genetic analyses surprisingly depicted high similarity between L. campechanus and L. purpureus, compatible with the hypothesis of a single species of red snapper for the Western Atlantic Ocean. These preliminary but very curious findings open an important discussion regarding the legislation involved on the capture of this overexploited fish resources as well as regarding their taxonomy.
Geometric models for higher Grothendieck-Witt groups in A1-homotopy theory

We show that the higher Grothendieck-Witt groups, a.k. a. algebraic hermitian K-groups, are represented by an infinite orthogonal Grassmannian in the A1-homotopy category of smooth schemes over a regular base for which 2 is a unit in the ring of regular functions. We also give geometric models for various P1- and S1-loop spaces of hermitian K-theory.
Morphological characterization of 51 kenaf (Hibiscus cannabinus L.) accessions in Nigeria Caracterización morfológica de accesiones de kenaf (Hibiscus cannabinus L.) en Nigeria

Fifty-one accessions of Hibiscus cannabinus L. were evaluated for 14 morphological parameters in Ibadan, southwestern Nigeria. The correlation matrix of the quantitative parameters was used to perform principal components (PC) analysis to understand the relative contributions of each trait to the variation observed, while Fastclus procedure was used to cluster the accessions into five groups. The most widely varied traits were earliness, number of apical branches and leaf lobes per plant with 483.3, 97.9 and 60.6% coefficients of variation, respectively. Correlation between fibre yield parameters and earliness was negative and significant. The first three PCs explained 66.23% of the variation, with only number of apical branches not highly weighted by any of the PC. The five clusters were distinguished by earliness, plant height, fibre yield, stem spine density, stem girth and apical branching. The variation was seen as a manifestation of environmental response in addition to the genotypic constitution. These results will aid in parent selection during breeding programmes.
The Elastic Property of Bulk Silicon Nanomaterials through an Atomic Simulation Method

This paper reports a systematic study on the elastic property of bulk silicon nanomaterials using the atomic finite element method. The Tersoff-Brenner potential is used to describe the interaction between silicon atoms, and the atomic finite element method is constructed in a computational scheme similar to the continuum finite element method. Youngźs modulus and Poisson ratio are calculated for [100], [110], and [111] silicon nanowires that are treated as three-dimensional structures. It is found that the nanowire possesses the lowest Youngźs modulus along the [100] direction, while the [110] nanowire has the highest value with the same radius. The bending deformation of [100] silicon nanowire is also modeled, and the bending stiffness is calculated.
Torque Vectoring for Electric Vehicles with Individually Controlled Motors: State-of-the-Art and Future Developments

This paper deals with the description of current and future vehicle technology related to yaw moment control, anti-lock braking and traction control through the employment of effective torque vectoring strategies for electric vehicles. In particular, the adoption of individually controlled electric powertrains with the aim of tuning the vehicle dynamic characteristics in steady-state and transient conditions is discussed. This subject is currently investigated within the European Union (EU) funded Seventh Framework Programme (FP7) consortium E-VECTOORC, focused on the development and experimental testing of novel control strategies. Through a comprehensive literature review, the article outlines the stateof- the-art of torque vectoring control for fully electric vehicles and presents the philosophy and the potential impact of the E-VECTOORC control structure from the viewpoint of torque vectoring for vehicle dynamics enhancement.
High sensitivity giant magnetoimpedance (GMI) magnetic transducer: magnitude versus phase sensing

This paper presents the results of investigations recently done by our research group that lead to a new and much better approach to the design of GMI (giant magnetoimpedance) magnetic transducers, which considers the changes in the impedance phase characteristics of GMI sensors due to varying low-intensity magnetic fields, instead of the usual impedance magnitude characteristics considered in the GMI literature. The development process of this new class of magnetic field transducers is discussed, beginning with the definition of the ideal conditioning of the GMI sensor elements (the dc level and frequency of the excitation current and the sample length), proceeding to compare the differences observed between the impedance magnitude and phase of GMI sensors and closing with the electronic circuits that condition ribbon-shaped GMI sensors and read their phase or magnitude variation as a function of the longitudinal magnetic field. Simulation studies, including the full electronic circuit and based on the experimental data obtained from measured GMI curves, have shown that an improvement in the sensitivity of GMI magnetometers larger than ten times can be expected when phase-based transducers are used instead of magnitude-based transducers. Finally, it is also shown that phase-based transducers are highly adequate for miniaturization purposes.
ANTIMICROBIAL EFFECT OF HYDRO-ALCOHOLIC EXTRACTS OF TRIBULUS TERRESTRIS, PHYLLANTHUS AMARUS AND HEMIDESMUS INDICUS AGAINST COMMON BACTERIAL URINARY PATHOGENS- AN IN VITRO STUDY

Context : Urinary tract infection (UTI) is one of the most common infectious diseases in the community. Moreover, with rapidly emerging resistance to antibiotics it is becoming increasingly difficult to treat such infections. Herbal extracts against a wider range of bacterial strains can be used as an efficient herbal drug for UTI. Aims : The primary objective of this study was to detect the in vitro activity of selected Hydro-alcoholic (40:60) extracts of three plants viz. Tribulus terrestris (Drug-1) (fruit extracts), Phyllanthus amarus (Drug-2) (whole plant extracts) and Hemidesmus indicus (Drug-3) (Root extracts) individually and in combination against the isolated bacterial pathogens showing antimicrobial resistance Materials and Methods : This study was conducted for a period of 3 months in the Department of Microbiology. Patients with history of recurrent UTI were included in the study population. Fifty isolates (n=50) showing multidrug resistance isolated from clinical samples are taken for the study Results : The extracts of Tribulus terrestris (Group A) , combinations of Tribulus terrestris with Hemidesmus indicus (Group F) and of Tribulus terrestris, Phyllanthus amarus and Hemidesmus indicus (Group G) inhibit both Gram positive and Gram negative bacteria, while Hemidesmus indicus (Groups C) inhibit only Gram positive bacteria. The Gram positive bacteria are more susceptible to these extracts than the Gram negative bacteria. All the herbal extracts tested showed more than 70 % sensitivity to the study group. Conclusions : The hydro-alcoholic extracts of Tribulus terrestris , Phyllanthus amarus and Hemidesmus indicus can be used effectively in the treatment of multi-drug resistant strains causing urinary tract infection. An effective drug could be developed from combination of these herbal extracts which would be natural, more economic and free of any side- effects.
The Price Impact of Economic News, Private Information and Trading Intensity

In this paper we use three years high-frequency data to investigate the role played by public and private information in the process of price formation in two secondary government bond markets. As public information we examine the impact of regularly scheduled macroeconomic news announcements. We identify those announcements with the greatest impact on these markets. As private information we estimate the price impact of order flow. In fact, according to the microstructure models, private information in this context is related to the subjective evaluation of information and order flow can reflect difference of opinions among market participants. Thus, market participant may infer information about the subjective beliefs of other market participants looking at the aggregate order flow. We then use a vector autoregressive model for prices and trades to empirically test the role played by intraday trading intensity and by the waiting time between consecutive transactions in the process of price formations.
