Performance appraisal (PA) is regarded as an effective tool of Human Resources Management used to measure the frameworks set by any organization to its employees by tracking individual contribution and performance against organizational goals. For organizations to achieve a competitive edge, a good performance Appraisal system must be put in place. This study was carried out to ascertain effects of Performance Appraisal on employee performance in National Bank of Kenya. The specific objective of the study were to determine the Communication, Administrative, Employee Development and Employee Behavior effects of Performance Appraisal on employee performance at National Bank of Kenya. The study adopted a descriptive research design as it intended to gather quantifiable information to be used for statistical inference through data analysis. This was because this method clearly shows effects of Performance Appraisal on the overall employee performance. The target population in this research comprised of 103 employees of National Bank of Kenya limited 5 Branches in Mombasa County. The sampling technique adopted in this research was stratified Random Sampling and a sample size of 56 employees was selected for the study. The main instrument of data collection used in this study was questionnaire which was administered to management staff, clerks and Direct Sales Representatives. The study used descriptive analysis which involved a process of transforming and presenting a mass of raw data into tables, charts, with frequency distribution and percentages. The collected data was analyzed using the Statistical Package for Social Sciences (SPSS) program version 21.Correlation and multiple regression analysis were used to determine the relationship between dependent variable and the independent variables. Descriptive statistics were represented by use of frequencies, measure of central tendencies (the mean, medium and mode) and also measure of dispersions (standard deviation, range and variance).Inferential data analysis was done by using the Pearson Correlation Coefficient which tested the hypotheses, regression analysis and multiple regression analysis. The research study found out that there was a positive and significant relationship between Communication and Employee Performance with a p-value of 0.001 which is below the required value of 0.05 level of significance. There was also a significant and positive relationship between Employee Behavior and employee Performance with a p-value of 0.016 which is less than 0.05 significance level. However an insignificant relationship existed between Administration and employee Performance with a p-value of 0.169 which is above the value of 0.05. Similarly the relationship between Development and Employee Performance and was insignificant with a p-value of 0.669 which is greater than 0.05 significant values. This indicated that performance appraisal according to this study has a great effect on employee performance in Kenyan commercial banks. The study further recommended that all institutions in the banking sector should embrace performance appraisal practice in this study as it greatly influences performance of employees.

EFFECTS OF STRESS IN EMPLOYEE PERFORMANCE AT HOTEL ACCORD PUDUCHERRY In recent years the rise in stress has seen across all spheres of life, particularly in the Workplace. Stress in organizations is a widespread phenomenon with far-reaching practical and economic consequences. Various studies have been conducted to examine the relationship between job stress and job performance. Job performance can be viewed as an activity in which an individual is able to accomplish the task assigned to him/her successfully, subject to the normal constraints of reasonable utilization of the available resources. In carrying out the study, convenience sampling technique was used to select 80 employees of the HOTEL ACCORD who have worked at least 3 years. Relevant data were collected using a structured questionnaire. The researcher found by using appropriate statistical tools to test the hypothesis. Based on these findings, strategies are suggested to reduce the level of stress among employees in the research area.

This Privacy preserving is most popular study for the research field. Privacy means gives the protection to the private information at preserving time. In Market place, discovery of frequent item sets using association rules mining is one of most important tasks in mining. Association rules is very helpful for finding frequent item sets to predicate about which item sets purchased together in a market and generate qualitative information that is useful for decision making. For distributed environment, database may be distributed as horizontally, vertically or mixed in computer network. The main problem in secure mining with the help of association rules is that transactions are distributed as vertically and the various sites want to find frequent item sets by participating themselves without discovering their individual data. The proposed method will find frequent item sets for vertical distributed database with the help of data miner using encryption based technique. Each sites prepare matrix with the local frequent item sets as per minimum support and encrypted it than send to other sites. The Scalar product with Boolean matrix is used for finding frequent item sets with secure computation between multiple sites without disclosing private input which improved efficiency and privacy of system.

In silico studies have been helpful in identifying the potential lead molecules with reduced cost. The chemical structure of a drug determines its physicochemical properties, and further determinates its absorption, distribution, metabolism, excretion and toxicity properties and ultimately affect the pharmacological activity. Medical chemists can regulate the pharmacological activity of drug molecule by modifying their structure. Unsaturated(contain two double or triple bonds), partially unsaturated(contain at least one double or triple bond) and saturated(contain no double bond or triple bonds) ring systems are important components of a drug. In this study, a serious of 27 five-membered heterocyclics were subjected to frontier molecular orbital(FMO) analysis and nonlinear optical(NLO) property identification by using density functional theory(DFT) calculations. DFT based global reactivity descriptor calculations have emerged as powerful tools for studying the reactivity, selectivity and stability of chemical and biological systems. Molecular orbital analysis exhibits relatively high(low) energy gap of the studied molecules, indicating that it would be kinetically stable(unstable). Pharmacokinetic properties and toxicity risks were studied using various programs like OSIRIS and Molsoft. In addition, we also verified the drug score, which combines drug likeness, cLogP, LogS, molecular weight(MW), and toxicity risks in one value and this may be used to judge the compounds overall potential to qualify for a drug.

A Hanslope Soil health was investigated from context of enzyme activities namely: cellulose, phosphomonoesterase and urease to enhance the understanding of the following land management practices: grassland under permanent pasture on 5 y ley to stocking, another sown with red clover a y before stocking, the other fertilized with N-fertilizer a y to stocking; the last on barley; with pristine deciduous woodland as control. The highest cellulose activity was detected in deciduous woodland, 172.3 ± 106 µg glucose g-1 d-1 over the summer. Cellulase activity was positively dependent on soil microbial C (R2 = 0.64). Grassland under permanent pasture treated with N-fertilizer a y before stocking had the highest urease activity, 77 ± 57.8 µg NH4-N g-1 h-1 over winter in both buffered and non buffered measurement techniques. There was no significant differences in phosphomonoesterase activity between land management. Soil enzyme measurements is a major component of soil health. It defines biological productivity, promote environmental quality and maintains plant and animal health. Soil health is fundamental for agricultural sustainability. Amongst the soil biological properties, enzymes show extraordinary specificity in catalyzing biological reactions as revealed in this study. Regional information are solicited for global network.

Gradual development in power systems has caused so many problems in control and optimum using of electrical storage systems. Storing of electrical energy has made new capabilities in improving the current control methods.

Oncoba spinosa is traditionally reputed for its medicinal potential particularly in southwestern part of Nigeria for the treatment of diabetes and cancer. 500 g of the leaves were extracted with 70 % aqueous ethanol and sequentially partitioned with hexane and chloroform. The various extracts were tested for the presence of secondary metabolites and subsequently screened for ?-glucosidase inhibitory, radical scavenging and cytotoxicity activities. Alkaliods, flavonoids, tannins, sterols, and anthraquinones were detected in various extracts while saponin was absent in all the extracts. The crude and aqueous extracts showed better activities than the standard antidiabetic drug (acarbose) in concentration dependent manner. The aqueous and chloroform extracts had antioxidant activities comparables to ascorbic acid at concentrations 125 and 250 µg/mL. The brine shrimps lethality assay indicated the cytotoxicity of the crude, chloroform and hexane extracts, this was further established using cervical (HeLa) and Lung (A549) cancer cell lines. The results support the folkloric use of the plant as antihyperglycemic and antineoplastic.

Plants often experience both drought and salinity stress in arid environment. Various mathematical water uptake models exist for plants response to combined drought and salinity stress. The reduction functions are classified as additive, multiplicative and conceptual models. In this study six different macroscopic reduction functions, namely; Van Genuchten (additive and multiplicative), Dirksen et al., Van Dam et al, Skaggs et al and Homaee were evaluated. The experiment was carried out on Ghods variety of wheat crop in a factorial split plot design with 3 replicates in the Research Field of university Birjand. The treatments consisted of four levels of irrigation (50, 75, 100 and 120%of crop water requirement), and three water qualities (1.4, 4.5, 9.6 dS/m). The results of this study indicated that the additive model estimates relative yield less than actual amount. In other word, the effect of combined stresses on wheat yield was less compared to sum of the separate effects due to salinity and water stress. The effect of drought stress on reduction of yield was more than salinity stress. The results also revealed that reduction function of Skaggs et al and Homaee were better fitness to measured data than the other functions.

Education is an important stand-in for human development. Along with economic growth and empowerment, it forms the core of every social and human development doctrines. Higher education as we have today is outcome of a long socio-cultural growth. The General Agreement on Trade and Service (GATS) is among the World Trade Organization’s most important agreements. The creation of the accord was one of the landmark achievements of the Uruguay Round and is the first and only set of multilateral rules and commitments covering Government measures that effect international trade in services. However, during the last four decades, the state had made considerable progress in all the areas of development. In this paper accounting of major objectives, i) to study analyze the GATS and Indian Higher Education ii) identify present status of the Indian higher education iii) the examine the policy suggestion and summary. Study will cover of India and regional centers will make use of based on secondary data. The analysis of growth, regional variations, state assistance to determents factors like higher education impact on GATS will be based on secondary data collected from the Reports documents published by such other agencies, using CAGR. Hence the very success of economic reform policies critically depends upon the competence of the human capital and in particular the specialized human capital. In this paper an attempt has impact on GATS and Higher Education in India.
