Due to the raising concerns about chemical and synthetic pesticides hazards on the environment and the human health, there is a trend to using botanical and natural pesticides increased. To this end, Salvia officinalis L., Lavandula angustifolia Mill and Nepeta pogonsperma Jamzad & Assadi as the potential plants for pest control can be used. The present study was conducted to identify chemical composition, fumigant toxicity and repellence activities of the essential oils from these plants against Sitophilus oryzae L. Dried aerial parts of the plant were subjected to hydro-distillation using a modified Clevenger-type apparatus. The composition of the essential oil was analyzed by gas chromatography and mass spectrophotometry (GC/MS). The experiments were conducted using a complete randomized design with 5 replications at laboratory conditions (28±1 ˚C, 70±5 % R.H. and 12:12 h dark:light). The major components of S. officinalis, L. angustifolia and N. pogonosperma were Thujone (37.29%) and 1,8-cineol (41.3 and 34.86%), respectively. All the tested plants showed insecticidal activity against S. oryzae. The LC50 values of essential oils for S. officinalis, N. pogonsperma and L. angustifolia, were estimated 148.19, 150.49 and 156.72 µl/l air against S. oryzae, respectively. The results showed that the essential oil of N. pogonosperma strongly repelled S. oryzae (86.5%) compared with the essential oils from S. officinalis and L. angustifolia (67 and 61.5%, respectively).

Human dignity is identified as the backbone of human right and its preservation is also taken as the key of permanent progress and development in every society. Therefore, internalization of organizational culture in light of Islamic values, human dignity and reverence for human and social capital is considered as the main and crucial policy in organization’s administration system and the implementation of such a planning is the primary purpose of many organizations. To delve into this issue in this study, as a qualitative study including meta-synthesis method, this study was an attempt to propose a comprehensive model of personnel human dignity in government agencies. To do so, the components of this phenomenon were identified in the early stages of investigation. Thereupon, the concepts and the components of personnel human dignity were emerged as a result of elite and expert consultation and also the analysis of primary conceptual model. In a bid to apply the exploratory model in terms of meta- synthesis method, the study was conducted through administering a questionnaire among population of 218 personnel affiliated to the department of real estate and registration office in Azerbaijan who was randomly selected based on stratified sampling method. To analyze the data, the confirmatory factor analysis and LISREL software analysis were also run in this study. Thereupon, the components and the parameters of human dignity model were emerged as the result of analysis. Moreover , in an attempt to identify the optimized dimensions of human dignity, 40 questionnaires were also administered among personnel of the Iranian army ground force in Maragheh who were randomly selected based on purposeful sampling method. Moreover, data analysis was run through fuzzy modeling in Matlab software. The findings revealed that in terms of significance of human dignity components, if the personnel pay more attention to the components of human dignity including performance dimension (33%), behavioral dimension (31%), mental and intellectual dimension (30%) and physical dimension (6%), consequently, human dignity of an organization will possess the highest rank in terms of value (62.1).

This research aims to evaluate the effects of information technology governance maturity on knowledge management processes. This research formulated as a descriptive survey. The survey sample population consisted of 469 randomly taken experts who work in IT companies of Iran, according to a cluster random sampling skim. We Used semi-structured interview with sophisticated experts for the extraction of evaluation factors. The information technology governance maturity was evaluated by means of COBIT’s Infrastructure. Relationships between maturities of knowledge management processes with the information technology governance formulated as 8 hypotheses. To examine the hypotheses we used Granger-Cause test and vector auto regression. results revealed that IT governance has effect on knowledge transfer, knowledge storage and knowledge utilization. Thus, by increase in the IT governance in an organization, we might expect the facilitation of knowledge management processes. Originality/Value: The relationship between information technology maturity and knowledge management processes first evaluated by this research.

Information accompanied with the technology supporting it is valuable asset in many organizations. As organizations are highly depended on IT, implementing IT effective governance is necessary for them. IT governance areas affecting business are strategic alignment, risk management, performance management, resource management and providing value. Successful performances need a mix of structures, processes and relational mechanisms. At the same time, organizations may need to have different combinations of these mechanisms. The purpose of this research is to prioritize IT governance mechanisms based on focus areas in to choose the most effective one for the implementation of IT governance. The main question of this study is that, for establishing effective IT governance in Saipa, which mechanism of IT governance is more important? In order to answer the question, by using company's experts in the field of information technology and multi-criteria decision-making methods, the weight of IT governance focus areas are determined and then the prioritization of IT governance mechanisms is done by the use TOPSIS method. The results represent that in structures mechanisms, functions of IT governance and committees are of the highest importance. Also, in process mechanisms, the main processes of IT governance and performance evaluation have the highest value. Although relational mechanisms have lower priority, account management, knowledge management and leadership are more significant.

This study aimed to investigate the quality of effluent water of a large shrimp farming complex in Chabahar region in Sistan and Baluchestan province (Iran). Fifteen sampling stations were designated in three distinct areas of these farms; i.e. the water supply canal, the drainage canal and the receiving area of the farm effluents in Gwatar Gulf. Water samples were taken from June to December 2004 for measurement and monitoring of nitrate, nitrite and ammonia compounds. The results revealed that the shrimp farms effluents have a profound effect on the water quality and aquatic environment of the drainage canal and the Gwatar Gulf. The average concentration of nitrate, nitrite and ammonia remained considerably higher in the drainage canal and Gwatar Gulf compared to the supply canal throughout the study. The amount of these compounds increased considerably in the drainage canal during the final stages of culture period and in Gwatar Gulf at post monsoon. The results of one way analysis of variance (at P<0.01 level) showed that all physical and chemical factors except water temperature were significantly different between stations. Considering that more than 25% of the shrimp farms of this complex were active during this study the measured values of nitrate, nitrite and ammonia compounds in the effluents were at the optimum range recommended for the shrimp farms.

Equine infectious anemia (EIA) is caused by the equine infectious anemia virus (EIAV), which infects the animals in the family Equidae and is classified in the subfamily Lentivirinae of the family Retroviridae. The disease leads to fever, hemolytic anemias, icterus, depression and chronic weight loss. This study was conducted on 287 horses (200 male and 87 female) in Tabriz area in Iran in order to determine the seroprevalence of equine infectious anemia. Blood was collected from all horses and the sera were analyzed for the presence of antibodies to equine infectious anemia virus (EIAV) using an ELISA test with IDEXX kit. The mean of Optical Density (OD) was 0.372± 0.016. In these samples the lowest and highest levels were 0.273 and 0.511 respectively. There was no positive case according to the observed results. Mean OD was 0.381± 0.014 in male horses and 0.387±0.010 in female horses, and there was no significant difference between the two groups (P= 0.356). The horses were studied in four age groups: 1-3 (54 horses), 3-6 (125 horses), 6-9 (70 horses) and over 9 years old (38 horses). Mean OD was 0.373±0.011, 0.381±0.012, 0.383±0.009, 0.388±0.017 in these groups respectively. The results revealed that none of the horses were positive for antibodies to EIAV.
