    In order to evaluate the relationship between morphological characters in rice lines two populations at F3 generation were grown in research field of Agricultural Sciences and Natural Resource University, Sari, Iran, during 2012. Statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grain yield. Result of correlation analysis revealed positive and significant relation of grain yield per plant with panicle length, panicle per plant, total grain number and filled grains per panicle. Path coefficient analysis indicated that filled grains per panicle had highest direct effect on yield followed by panicle length, plant height, and panicle per plant. Panicle per plant had highest indirect effect on grain yield. This study revealed that selection based on filled grains per panicle, panicle length and panicle per plant will be highly effective for yield improvement in rice breeding programs

    This study investigates the effects of financial management practices and their role in economical development and organizational performance. Economic environment is changing rapidly and this change is characterised by such phenomena as the globalization, changing customer and investor demands, ever-increasing product-market competition. To compete successfully in this environment organizations continually need to improve their performance by reducing costs, innovating products and processes and improving quality, productivity and speed to market. The impact of talent management on organizational performance is a problem especially where only strategic staffs is treated as talents of the firm. Positive development is easier to achieve when everyone is on a common path in the organization. It is viewed in this particular study that strong organizational culture is very helpful for the new employees to adopt the organizational culture and to get the competitive advantage under the particular conditions. On the behalf of previous studies it is bring into being that employee’s commitment and group efficiency plays very crucial role to adopt the value and beliefs of the organization and enhancing the performance of the organization. Organizational culture has a deep impact on the performance of employees that can cause to improve in the productivity and enhance the organizational performance

    Chickpea (Cicer arietinum L.) is one of the most important crops worldwide that is a subject of many plant breeding programs in many countries. In addition, climates are changing all over the world and drought becomes one of the most serious problems versus yield of crops. In order to screen drought tolerant genotype in Chickpea, twenty genotypes were tested under rainfed and irrigated conditions in the experimental field of College of Agriculture, Razi university, Kermanshah, Iran during 2008- 2011 growing seasons. Descriptive diagrams of hundred seed weight (HSW), number of pod per plant (NPPL), number of seed per pod (NSPO) and grain yield (GY) exhibited high GE interaction and variability between the investigated characters indicating possible selection of drought tolerant and stable entries. Analysis of variance revealed highly significant differences (P<0.01) between the genotypes and environments exhibiting genotypic diversity and variability between genotypes and environments. GE interaction was highly significant for HSW and NPPL but non-significant for GY and NSPO. Based on mean comparisons of GY, HSW, NPPL and NSPO, 2, 7, 8 and 3 classes of genotypes were found, respectively. The results extracted from path analysis over environments showed the contributions of NSPO (=0.82), HSW (=0.54) and NPPL (=0.12) on adaptability of grain yield, therefore the most contribution was attributed to number of seed per pod in the phenotypic stability of grain yield

    Synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants The concept of synchronization energy and protein was first by Jhonson, Implying that maximum microbial protein synthesis could be achieved by matching the rate of Organic Matter and protein degradation. Synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants. Feed protein are degraded by microorganism in the rumen via amino acids into ammonia and branched chain fatty acids. Non-protein nitrogen (NPN) from feed and urea recycled from saliva and from the blood across the rumen wall also contribute to the ammonia pool. Microbial protein synthesis is important for ruminant. Current concepts of ruminant nutrition focus on maximizing ruminal microbial protein production.  Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. The major nutrients that are considered pollutants from agricultural systems are nitrogen (N), phosphorus, and methane. Therefore, the goal of this discussion is to provide  information to aid in reducing N excretion from animals while maintaining a high level of production that is economically efficient

    In order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in Isfahan region. Protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and Pollen. Results showed that the longevity of caged honey bees in incubator was significantly affected by dietary treatments (P<0.05). Wheat gluten supplement and lentil substitute resulted in the highest (61 days) and lowest (9.2 days) longevity of bees in 50% mortality, respectively; while in 100% morality pollen and lentil substitutes caused the highest (143.5 days) and lowest (20.7 days) longevity of bees, respectively. Field experiments showed a significant difference between feed intake in experimental colonies. Honey bees consumed the most amounts of pollen cakes, while bread yeast and soybean cakes were consumed more than soybean meal and wheat gluten; however, fish meal cakes were not accepted by bees. Brood area of experimental colonies was significantly different and varied from 13050 to 22680 cm2. Honey production in test colonies was also significantly (P<0.05) different and varied from 5.98 to 9.56 kg. After 90 days of overwintering the experimental colonies fed with pollen supplement and substitute cakes showed a significant (P<0.05) difference in honey consumption, total bee mass reduction and laying area of queens. Dietary inclusion of pollen and wheat gluten supplements caused the lowest bee mass reduction, and respective colonies had the greatest laying area at the end of winter. Overall, the present results showed that soybean flour and bread yeast can be used as pollen supplements and substitutes cakes

    To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2= two times cultivation at 3 and 5-leaf stages using a duck foot cultivator, W3= hand weeding throughout growing season and W4= without weeding) as main plots, and two plant density levels (D1= 190000, and D2= 266000 plant ha-1) and two plant pattern levels (P1= one-row and P2= two-row) as sub plots. Weed density, weed biomass, number of leaves (NL), stem diameter (SD), number of tillers (NT), plant height (PH), leaf area index (LAI), dry matter yield (DM yield), dry matter digestibility (DMD), water soluble carbohydrates (WSC), crude protein (CP), acid detergent fiber (ADF), total ash (ASH), and crude fiber (CF) where measured. The results revealed that the highest weed density and biomass observed in not weeding treatment. There was not significant difference among one time cultivation at 3-leaf stage and two times cultivation at 3 and 5-leaf stages from the weed density and biomass point of view. The lowest NL, SD, and NT observed in not weeding treatment. Increasing plant density decreased DM yield, PH, SD and NL of sorghum. Two-row plant pattern showed a significant preference in comparison to one-row plant pattern from the DM yield point of view although the highest CP obtained in one-row plant pattern. The highest DMD obtained in P2D2. The highest ASH obtained in W2D2 and W2P2

    The aim of this work is to use Self Organizing Map (SOM) for clustering of locomotion kinetic characteristics in normal and Parkinson’s disease. The classification and analysis of the kinematic characteristics of human locomotion has been greatly increased by the use of artificial neural networks in recent years. The proposed methodology aims at overcoming the constraints of traditional analysis methods and to find new clinical ways for observing the large amount of information obtained in a gait lab. Self organizing maps (SOM) also called Kohonen maps are a special kind of neural networks that can be used for clustering tasks. The results are shown in the terms of sensitivity, specificity, accuracy, error rate from the two groups of features which are the Mean Coefficient of Variation and Mean Sum of Variation and Mean Max and Mean Standard deviation of the Ground Reaction Force. Results showing the potential of this technique for distinguishing between population of individuals with normal gait and with gait disorders of different causes of disease

    The present study was conducted to evaluate the effect of  training on personality formation and mental development of childhood and adolescence. It is important to understand how children develop physically, socially, emotionally and intellectually to know that all areas of development are equally as important as each other, and that all impact on one another. Biological and cognitive changes transform children’s bodies and minds. Social relationships and roles change dramatically as children enter school, join  programs,  and  become  involved  with  peers  and  adults  outside  their  families. The years between 6 and 14 middle childhood and early adolescence are a time of important developmental advances that establish children’s sense of identity. A child’s development can be measured through social, emotional, intellectual, physical and language developmental milestones.  All children and young people follow a similar pattern of development so the order in which each child advances from one milestone to the next will be roughly the same. However, each child will develop at a different rate and their development may not progress evenly across all areas

    A purpose of Zagros forests preservation plan is to reduce degradation factors through empowering woodman beneficiaries and underdevelopment of rural forested areas which appear as scattered agronomies inside and in forest margins, trees cutting for power supply, trees cutting for hay supply or making coal in forested regions. Therefore, natural resources experts believe that, by creation or improvement of sustainable occupation and increasing economic power of woodman families, current trend of degradation would be controlled and degradation factors would decrease by conducting rural youth population toward the jobs with lower dependence to forest. So, this plan with purpose of preservation, restoration and principled operation of natural resources and in order to study as participatory evaluation was carried out that, the results of this plan were suggested as a number of multi-stage solutions for implementation

    This paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. When a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near of Thai). It is similar to that of cooking in the Microwave oven. The finite difference time domain (FDTD) method is widely used as a computational tool to simulate the electromagnetic wave propagation in biological tissues. The FDTD method has been used for calculating SAR (specific absorption rate) values on human model by varying the EM radiation at frequency 1.47 GHz. Electromagnetic field effect showing at different position of the human model
