The present research looks into the examination of the relationship between role conflict and role ambiguity on job satisfaction. The main issue of research is that some factors are effective on role conflict which can stimulate amount of customer orientation and job performance on salespeople and the question is that to what extent are they effective? The research method is survey and descriptive-causal which is collected by salespeople in Iran furniture market. The Sample size was considered 320 issues and among them 370 questionnaires has been distributed because of non-return and non-precision. The main variables of this research are including role conflict, role ambiguity, and job satisfaction.

Since resource restriction does not allow organizations to be able to invest in all projects, they need to take into account essential measures such as priority of their projects in order to approach their strategic objectives. Organizations can select one among their set of strategic projects by performing assessments on them. To implement this process, which is a multiple-criteria decision making (MCDM) process, organizations need to involve experts and professionals. In many cases, assessments made by decision makers are not adequately certain and cannot be expressed as exact numerical values. This issue is compensated by applying certain methods to handle uncertainty. Grey decision-making method makes possible the ranking of projects based on qualitative criteria in uncertain environments. The procedure used in this research for the evaluation of strategic projects starts with extracting the appropriate attributes and determining the weights using the Grey theory. The procedure continues with performing the evaluation process based on qualitative attributes using a decision-making method based on the Grey systems theory (GPD method). At the end, a case study was performed on the strategic projects of the holding companies of the MAPNA Group with the aim of validating the proposed model. The results were considered reasonable and adequate by the experts and managers.

Defects in castings often lead to rejection, which would ultimately result in loss of productivity for a foundry. Today’s Modern philosophy of quality management enhances thrust on customer satisfaction and delightfulness by achieving continuous improvement in quality and service to reach customer satisfaction as their ultimate goal. ‘Process Failures’ was considered as one of the main disruptions excising and affecting the foundry process which when attended to can solve quality problems. In this paper we present how Foundry Total Failure Mode and Effect Analysis (FTFMEA) technique was used to solve a quality problem through planned data collection to identify and prioritize potential failures in a process. This study was conducted and implementation in foundry located at India, whose quality system had been certified according to the ISO 9000 standards. The process failures was found to be the root cause of this dragging problem, through planned data collection in co-operation with part of the internal staff chosen as FTFMEA team members. A detailed and in depth study was initiated by using the FTFMEA technique to assure product quality and as a mean to improve operational performance of the process. The problems identified in the various steps of foundry process contributing towards high rejection are studied and analyzed in terms of ratings to prioritize the attention for each of the problem. The recommendations of FTFMEA were validated by confirmatory trials. The recommendations were implemented as a standard operating practice. A database of defects and the causes was established, enabling one to associate the defects with the relevant process operations and the identification of their possible causes. As a result of implementation the occurrences of the dragging problem was substantially reduced.

In this research, the rate of soil erosion was calculated in Maragheh Sufi chai Catchment with an area of 24820 hectares and the sub-catchment of Kahak Darresi with an area of 4200 hectares using WEPP model and GeoWEPP program. The data was entered into WEPP model in the format of computer files of soil, climate, management, slope and floodway. In soil file, parameters were calculated for 22 identified horizons and fed into the model. 11 types of utility, management actions and the physiological and phenological features of the plants were entered in the management file the amount of rainfall and daily temperatures for 9696 days were calculated and entered in the model using Cligen in the climate file. The Slope and floodway files were obtained from the topographic map of 1:25000 using ArcGIS. The amount of sedimentation in Sufi Chai catchment was calculated to be 21.8 tons per hectare based on WEPP model and 14.53 tons per hectare based on sediment station\'s estimate. The annual amount of sediments in Kahak Darresi catchment using WEPP model was estimated to be 7.2 tons per hectare and 3.5 tons per hectare using the observational method in sediment estimation station. The model output is the indicative of more than one ton’s sedimentation in structure construction sites and shows high correlation between sedimentation site and the site of structures formation

To study water–stress-tolerant barley varieties, 20 barley lines were cultivated under full irrigation and limited irrigation conditions where irrigation was stopped at anthesis stage in two separate field experiments during the 2007-2009 growing seasons at the Saatloo Research Farm, Azerbaijan, Iran. The experiments were laid out using RCBD with three replications. The results from combined analysis of variance in both normal and stress conditions indicated that there were significant differences among genotypes with regard to all studied traits which were due to high variation among the genotypes. It was found that the activity of enzymes including SOD, GPX and CAT were increased under drought stress conditions, so that tolerant genotypes had more changes in enzyme activity. On the other hand, MDA, Dityrosine and 8-oHdg were increased under stress conditions where sensitive genotypes had more enzyme activity. Calculations of the correlation coefficients among the studied traits under both stress and normal conditions also indicated that there were negative and significant differences between antioxidant activity, lipid, protein, and DNA decadence. Finally, with regard to all traits, it was revealed that in normal conditions genotypes 18 and 19 were the best performing lines, whereas the genotype 14 was least adapted line. Therefore, genotypes 18 and 19 showed higher levels of resistance to water stress and the genotype 15 was more sensitive to the drought conditions. The results obtained also indicated that selecting more tolerant genotypes under stress conditions is the best way to overcome water deficit stress under terminal drought conditions.

The purpose of the present study was to assess the hepatoprotective potential of ethanolic extract of leaves of Phyllostachys nigra on Paracetamol (PCM)-induced hepatotoxicity. Variable doses of 250 mg/kg and 500 mg/kg of EEPN were administered orally for evaluating their hepatoprotective effect on PCM-induced hepatotoxicity in rats. Both doses (250 mg/kg/p.o. and 500 mg/kg/p.o.) were found to reduce the hepatotoxicity in rats. The increase in the levels reduced glutathione (GSH), tissue nitrite/nitrate and decrease in lipid per oxidation showed the antioxidant activity of the Phyllostachys nigra. Pre-treatment with EEPN reduced the biochemical markers of hepatic injury like serum glutamate pyruvate transaminase (SGPT), serum oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP), total bilirubin (TBIL) and total protein shows hepatoprotective activity. It was also found that EEPN at a dose of 500 mg/kg/p.o. was more potent as compared to EEPN (250 mg/kg/p.o.). The study validates scientifically the widely claimed use of Phyllostachys nigra as an ethanomedicine to treat hepatotoxicity.
