To study the effect of salinity experiment was performed in Astara region. Cultivars included Cultivated in two pieces of land in Astara: one with normal soil and the other with salty soil. Maize cultivars were experimented in three replications on the basis of randomized complete Block design. During the experiment, morphological characteristics concerning the plant growth, such as leaf numbers, Leaf length, Ear number, Ear weight, Seed weight in ear and Number of seed in row were measured. Results from the analysis of variance showed that there were no significant differences between different years. Between locations (normal and saline) in all traits, significant differences were seen. The greatest leaf numbers was seen in Zaqatala (13.96), K3653.2 (13.67) and S.C704 (13.28) and its least amount in Waxy (8.673) under the salty conditions. Salinity reduced the number of ears per plant. Between B73, Waxy and K3615.1 were not significantly different in normal and saline conditions. The maximum number of seeds in rows in Zaqatala, B73 and SC704 were observed that no significant difference was found between them.

Every organization has a kind of performance management system which is expected to satisfy important goals in the field of management of human capital management. Among these objectives we can refer to cases such as motivating the individuals for better performance, helping the individuals to extend their skills, developing performance culture, determining who is rightful, making decision about the individuals who perform weakly, and helping implementation of business strategies. In this research we are trying to present a model in order to design and compile a model for evaluation of performance of employees of bank Keshavarzi counter and presenting strategies to improve their performance. For this purpose, bank Keshavarzi has 103 branches in Tehran, and 81 heads of branches were selected as population of research. In this research the main variable is the feedback of evaluation of performance of the counters’ employees, made from the heads of branches through questionnaire. It should be noted that in this research six main variables of learning, education, performance evaluation standards, and performance evaluation scales were studied. Therefore based on statistical tests gained through the research, Bank Keshavarzi has realized its objectives in evaluation of performance of counter employees, awareness of employees about the standards and methods of the current evaluation methods and the degree of feedback from performance evaluation to counter employees are appropriate. Finally performance evaluation causes better discharge of duties by the employees of counters.

In this study,the effect of geometrical shape variationonaerodynamic coefficients and flow structure of asymmetric airfoils at low Reynolds number has been investigated.Then the optimum section geometry has been obtained. To do this, a 2D compressible unsteady flow around airfoil is simulated by solving NS equations. Validation of the study has been conducted on a symmetrical plungingnaca0012 airfoil and an asymmetrical fixed SD7003 airfoil at different angles of attack.Then the section shape analysis has been developed on the SD7003 airfoil. All section shapes are calculated by designfoil_r6 software. The Reynolds number and reduced frequency in all cases are selected 11000 and 2.01 respectively. According to the results of the analysis, enhancing the section thickness leads toincreasing the lift and reduction in the drag coefficients. In addition, by increasing the effect of camber and upward flap, the amount of lift rises significantly and drag enhances slightly in comparison to the origin section of SD7003 airfoil.

In this paper, a cluster based intelligent semantic query routing technique in peer-to-to networks has been proposed. The ant colony optimization technique is used for query routing and relevance ranking methodology selects the peers with good accuracy. This approach has drastic reduction in the overhead of network delay and improves the efficiency of the p2p networks. In this research work, an approach of query routing in peer to peer network has been proposed based on Trust and Caching mechanism .It can also offers secured and reliable routing. It also reduces the delay and overhead to great extent. An asymmetric cooperative cache approach for the cache mechanism and an intelligent caching mechanism for cache replacement policy for the new data packets entry as SPACE (Systematic P2P Aided Cache Enhancement). Replacement policy takes place through cache block eviction procedure algorithm in hierarchical manner starting from the bottom of the hierarchy. The advantage of this approach is that the network cost can be reduced by storing the data packets during the routing.

Leadership styles are those important variables forming organizational behavior and the way of thinking in organization. Hence, it seems that there is a significant relationship between leadership styles and policies taken for organizations whereby improving the human resources is a way which manifests this relationship. This paper is aimed at investigating policy analysis in governmental organizations with an emphasis on modern leadership styles. The questionnaire and SPSS software have been used as essential tools in this paper. 54.5% of data collection is comprised of men, also bachelor degree is the mean education status which average work experience is about 6-15 years. It has been concluded that the factor ‘innovation’ among all other factors had the most common points with improvement. It was specified through variance analysis and hypothesis tests that among three leadership styles including transformational, transactional and participative leadership styles, participative leadership style with standard β value (0.496) influenced human force improvement the most.

In this numerical study, the effect of choosing various viscous models on aerodynamic coefficients and the structure of the flow at low Reynolds (laminar zone) and at high Reynolds (turbulent zone) has been considered. The numerical simulation of an unsteady, two dimensional and incompressible flow on the oscillatory air foils through Navier-Stokes equations has been conducted in this survey. The viscous models applied in this study are Spallart-Allmaras.

The characterization and grading of glioma tumors, via image derived features, for diagnosis, prognosis, and treatment response has been an active research area in medical image computing. This paper presents a novel method for automatic segmentation and grade detection of glioma from conventional T2 weighted MR images. Segmentation of the tumor was done using spatial domain filtering techniques. The accuracy of segmentation method was compared with Fuzzy c-means clustering technique and validated with manual Ground truth images which produced promising results. Feature extraction was done using Statistical texture analysis by computing first order statistics and gray level co-occurrence matrix (GLCM) based second order statistical methods. Statistical significance of the features was determined by t-test and its corresponding p-value. A decision system was developed for the grade detection of glioma using these selected features and its p-value. The detection performance of the decision system was validated using the receiver operating characteristic (ROC) curve. The diagnosis and grading of glioma using this non-invasive method can contribute promising results in medical image computing.

Training creative, skilled and educated students are efforts of the education system, and raising levels of students\' motivation is one of the ways to achieve this goal. The aim of this was study relationship between achievement motivation and academic success in high school students. In this study, the method was casual comparative and two boys and two girls\' high school was selected for sampling, and 50 subjects were randomly selected from each high school. The overall samples size was 200 subjects (100 male and 100 female high school students). Finally Achievement Motivation Test ACMT was performed. The results showed that there was no significant relationship between male and female students in terms of achievement motivation. In this research also it was found that there was a significant relationship between achievement motivation and academic success in female and male students; so that academic success increased with increasing achievement motivation. Percentage of achievement motivation in females was more than males in top class. 22 of females had high scores, this percentage in males was 19. Percent of motivation in males in the middle class and upper the average was more than females. In the down class, the achievement motivation was the same for male and female students.
