The beet cyst nematode (BCN) (Heterodera schachtii), and beet curly top virus-severe (BCTV-Svr) (Curtovirus betae) are two important pathogens of sugar beet fields worldwide. Therefore, the reaction of 14 genotypes was separately assessed, using Jolgeh and Sanetta cultivars as susceptible and resistant controls, respectively, in completely randomized design experiments for BCN and BCTV-Svr. Reactions were based on the cyst and egg counts and symptoms severity index. Experiments were performed in the greenhouse of Tarbiat Modares University, Tehran, Iran, and were repeated twice independently. Based on the results of initial experiments, the S1-960090, S1-940324, S1-960294, and S1-960284 genotypes resistant to the BCN were selected for further investigation. Furthermore, the reaction of the four selected genotypes to BCN, BCTV-Svr, and the combination (mixture) of the two pathogens was evaluated by analyzing their growth, physiological, and biochemical characteristics, and virus accumulation. Resistant genotypes showed higher levels of defense-related enzymes such as catalase, guaiacol peroxidase, and polyphenol oxidase, whereas susceptible genotypes exhibited significant reductions in photosynthesis, greenness, and chlorophyll a, b, and carotenoid content compared to non-inoculated and resistant plants. This is the first study conducted to search for dual-resistance sources against two devastating pathogens that frequently occur in the sugar beet-growing regions of Iran. Based on the results of this experiment, genotypes S1-960090 and S1-940324 were identified as resistant to both pathogens and are recommended for breeding purposes.

Concentrations of lead (Pb) were found in the shells of the oyster Saccostrea cucullata and sediments in May 2010. Samples were obtained at four sites on Qeshm Island, at three sites on Hormoz Island, and at three sites in Lengeh Port along the intertidal coast of the Persian Gulf of Iran. The levels of Pb in sediments and shells were analyzed by graphite furnace atomic absorption spectrophotometer.Mean Pb concentrations in the different sampling stations varied between 613.94 and 0.06 µg g^-1 in the shells of S. cucullata and 180.78 and 0.86µg g^-1 in sediments. Biological effects criteria suggest that Pb concentrations in sediments in three sites from Lengeh Port were higher than ERL (effects range low), but at the all sites were lower than ERM (effects range medium). The present results support the significant differences in shell and sediments’ accumulated concentrations of Pb among sites attributed to input sources of human activities including urban, domestic, industrial, agricultural, shipping and transport, mining activities, and ports and harbors

The present study is interdisciplinary in applying philosophy through its collaboration with psychology and literature. This article examines hope according to the two great thinkers; Rumi, a Muslim mystic and writer, and Gabriel Marcel, a Christian existentialist philosopher. The purpose of this study is to provide a basis for the work of philosophical counselors and psychotherapists. For this reason, the views of Richard Snyder, the theorist and founder of hope therapy in contemporary psychology, are also introduced in the present study to bring Rumi and Marcel's views on hope closer to the topics of hope therapy, and the similarities are derived from being used by philosophical advisors. According to the findings of this research, the hope that Rumi speaks of is a clear and guiding hope that, if used properly, can become a positive moral trait in human beings; The hope that arises from man's need for God and will always be the way to man's spiritual progress. Marcel also considers hoping a tool for faith and closeness to the higher being, which causes a person to be spiritually ready to serve other human beings. This spiritual preparation frees man from the snare of the shattered world of which Marcel speaks. By comparing Snyder's theory of hope and Rumi's view of hope, we find similarities between the views of these two philosophers in the components of hope. The examination of Snyder's theory of hope and Marcel's view of hope also reveals the intellectual similarity of the two thinkers on the vital role of hope in life.

Different types of soil erosion including gully erosion occur in many parts of Iran. The west of Iran is further threatened by gully erosion due to its specific physical and climatic conditions. However, few studies have been carried out to study the sediment production of gully erosion in Iran. This research was therefore conducted to measure storm-wise sediment production of gully erosion in the west of Iran. To achieve the study objectives, 48 gullies located in three small watersheds viz. Darreh-Shahr, Abbas-Abad and Hollowsh in Ilam and Lorestan Provinces were monitored. The volumes of gullies were measured before and after 5 rainstorms for Darreh-Shahr and Abbas Abad watersheds and 6 rainstorms for Hollowsh watershed from 2005 to 2007. Sediment production was calculated on storm basis for each gully. The results revealed that the minimum and maximum volumes of gully erosion were 0.002 and 1.010 m³, respectively, for one millimeter of rainfall. The results indicated that soil moisture, percentage of silt and clay, amount and intensity of rainfall and drainage area were the most important factors on formation and sediment production of gully erosion.

Background: Helicobacter pylori is the most common cause of chronic infection in the human stomach. The infection has universe prevalence in all age groups. Probably, this bacterium is the cause of most common chronic bacterial infection in human beings and infects approximately half of the world population. H. pylori produces urease, an enzyme that degrades the urea in the stomach’s mucous to ammonia resulting in biochemical reaction that leads to increase in pH of the stomach lumen. This allows pathogenic intestinal protozoa to take the opportunity to cross through stomach’s increased pH and cause disease. The aim of this study was to evaluate the relationship between H. pylori infection and prevalence of parasitic infection in patients in Ilam. Materials and Methods: Following stool samples collection during 2013 in patients with abdominal pain in Ilam, Iran. H. pylori infection was investigated based on stool antigen analysis (HPSA) by enzyme-linked immunosorbent assay (ELISA) method in patients who had recurrent abdominal pain. Stool specimens were examined using the direct examination and the spontaneous sedimentation method for detecting the trophozoite and cyst of parasites. Results: In this study, we found 65 patients with H. pylori infection. Out of these 65 patients, the percentage of patients with positive results for Giardia lamblia was 30.7% and for Entamoebahistolytica/dispar was 12.3%. Conclusion: The results of this study suggest that H. pylori infection may provide favorable conditions for giardiasis infection; however, this presumption needs further studies with larger sample size.

Background: Students are the most dynamic people in the society and their health is to a great extent a prerequisite for the health of most individuals in the society. Musculoskeletal disorders (MSD) are one of the most important factors that effect on general health. This study was conducted to The Relationship Between General Health and MSD among Tarbiat Modarres University Students.
Methods and Materials: This descriptive-analytic study was conducted on 306 college students were enrolled by using nonprobability purposive sampling methods and also availability. Data was obtained based on the demographic data questionnaire, musculoskeletal researcher-made questionnaire and the standard General Health Questionnaire (GHQ-12). After collecting the required data, SPSS software version 23 was used for descriptive and statistical analysis (Spearman/Pearson chi-square, phi Cramer’s V).
Results: The results showed that 60.6% and 72% of male and female students had desirable general health. Also, the findings showed that general health decreases with age growth (P = 0.015). Among the musculoskeletal disorders, only low back pain and neck pain were associated with general health, as students who suffered from low back pain and neck had an unhealthy public health (P < 0.05).
Conclusion: The results of this study showed a high prevalence of general health disorders and musculoskeletal disorders among students. Musculoskeletal disorders have a profound effect on the general health of students, thus jeopardizing their general health. Therefore, consideration should be given to the factors causing these disorders and the appropriate planning to overcome it.

Gel treatment is one of the most promising remedy methods to improve conformance in heterogeneous reservoirs for better sweep efficiency. In this paper, new enhanced preformed particle gels (PPGs) for conformance control at the Balal reservoir are introduced. In these PPGs, three species of 2-acrylamido-2-methylpropane sulfonic sodium salt (AMPSNa), acrylamide (AM) and N-vinylpyrrolidone (NVP) monomers have been used to synthesize via free radical crosslinking polymerization at room temperature using N,N-methylenebis (acrylamide) (MBA) as a cross linker. The swelling properties of the PPGs were enhanced by adding the Nano clay Montmorillonite Na+. A temperature stability agent was also used to make these special PPGs compatible with high temperature and salinity reservoir conditions. Then, PPGs were kept in Balal reservoir conditions in order to study their stability in harsh reservoir conditions. To this end, combination of 50 samples of the preformed particle gel has already been constructed by design of experiment using response surface method, and finally a new model for predicting the swelling ratio of the preformed particle gel based on the weight percentage of material and in different salinity is provided. The results of this research show that the crosslink has more influence on the swelling ratio, and PPG with the optimal formulation will able to guarantee the hard reservoir conditions (temperature 82˚C & salinity 260000ppm).

In his book, Finite and Infinite Goods, The prominent Christian philosopher, Robert Adams, defends a weak version of divine command theory. According to this view, the nature of moral obligations is identical with being commanded by God. His argument for view has two stages. In the first stage he tries to show that the notion of moral obligation is essentially social in its nature. That is, moral obligations are constituted by social notions such as demands or commands of a third party such as a third person or the moral community. In the second stage he argues that this third party cannot be anything but God. In this paper I will try to criticize his argument in its first stage. I will show that his reasons and arguments for the claim that moral obligations have a social nature are inconclusive.

This paper is based on an interpretive ethnography conducted in a public organization ("Edareh"). This paper attempts to achieve some part of the ethnography’s goal to describe how "ideal worker" is socially constructed by the different organization’s stakeholders (managers and employees), so as to stay and to be “advantaged". This goes through the light of analyzing the two key events, that is to say "management changes" and "layoff". At first, drawing on Schneider and Ingram framework, the characteristics of “ideal worker” construct from new managers’ view, their sense making of the employees with this framework and trying to move into the full realization of the construct is expressed. Then, based on social construction efforts on the part of employees, their struggles to stay, to not being fired, and even to get promoted - intended to changing and modifying the new manager’s “ideal worker” construct - is described in the form of a manifesto for staying in “Edareh”.

In today's dynamic environment, having a proper strategy is not enough for companies to be able to adjust themselves with their environments. Companies through choosing a suitable organizational structure can benefit innovation to achieve sustainable competitive advantage. The aim of this study is testing the mediating role of organizational structure (formalization, centralization, complexity) between environmental uncertainty and organizational innovation. The questionnaire was used to collect data with high reliability and Structural Equation Modeling and Partial least squares were used for analyzing data. Data collected from medium and large manufacturing firms in the Mashhad city. The results showed that the theoretical model was good fitted and the relationship between environmental uncertainty and dimensions of Organizational structure (complexity, formalization and centralization) is meaningful. Also the relationship between complexity and formalization with organizational innovation were significant. Organizational formalization and complexity mediated between environmental uncertainty and organizational innovation was meaningful but mediating role of centralization was not meaningful.

In recent years, the Russian Wheat Aphid, has been included worldwidely in the list of the important pests of cereals, particularly wheat plants. In addition to direct serious damage, the aphid is the main vector of Barley Yellow Dwarf, Barley Mosaic, and Sugarcane Mosaic Viruses. The pest was reported from East Azarbaidjan province (Iran) a few years ago and it is now widespread in Tabriz, Ahar and Kaleybar wheat fields. In the present study, the possibility of any resistance was looked for at the tillering stage in Sardari, Sabalan, Alvand, Zarrin and Alamoot, the most extensively planted varieties in the province. The experiment was conducted under glasshouse conditions of 24.4±1.6 oC with 50- 60% R.H. and a photoperiod of 14:l0(L:D). Antibiosis was determined by studying the percentage survival of the nymphs, their developmental time, and fecundity (total number of progeny per /female produced within the first 10 and 15 days of the reproductive cycle) calculating the relevant intrinsic rate of natural increase (rm values). The analysis of variance indicated that, regarding the last two parameters, there were significant differences (P<0.05) between the varieties. The highest (43.21±5.45) and the lowest (34.43±8.91) average numbers of progeny within the first 10 days were observed in those reared on the Sardari and Zarrin varieties respectively but the figures obtained within the first 15 days were found to be 49,43±13.31 on Alamoot and 58.86±9.45 on Sardari. Also the highest mean “rm” value (0.3399±0.01) was estimated for rearings on Sardari with the smallest (0.2889±0.03) on the latter. At present, Sardari seems to be more likley susceptible to the aphid amongst the others. Field trials and experiments on later phenological stages of the wheats and potential role of other resistance mechanisms is going on.

The influence of initial moisture content on wood decay at different levels of atmospheric oxygen concentration was studied. Three fungi, Coriolus versicolor (C. versicolor) a white rot, Coniophora puteana (C. puteana) a brown rot, and Chaetomium globosum (C. globosum) a soft rot, were chosen. The mycelia of the fungi were inoculated in to mini blocks of Fagus sylvatica (beech) and Pinus sylvestris (Scots pine). Incubation was conducted under four levels of oxygen concentration (1,5,10, and 21% O2) at 22o C. At low oxygen concentrations, an increase of moisture content had a negative effect on the wood decay process by both the Basidiomycetes (C. versicolor and C. puteana) in Scots pine and beech. In air, the effect of initial moisture content on wood decay by these fungi depended on the characteristics of the fungi and the wood species (such as fungal biology and physiology). When C. globosum was used as a colonizer, increasing moisture content generally increased weight loss in the wood blocks (especially in beech). When the moisture content in the wood blocks was increased, more sporulations by C. globosum were also observed on the wood samples. However, the role of oxygen in inceasing wood decay was more important than the moisture content effect.

The purpose of the present article is to  make a comparative  study of theme markedness in Persian and English medical texts. It aims to determine the similarities and differences of Persian and English with regard to markedness. The study has been done based on Halliday’s Systemic Functional Grammar (SFG) and is concerned with the textual metafunction of this approach. To accomplish the purpose of the study, several books and articles were selected in the field of medical sciences. The corpus contained 1000 randomly chosen clauses of written texts, the data were gathered in both Persian and English and the research method was descriptive-analytic. The restults indicated that in Persian medical texts, circumstantial adjuncts in the subject position have a high frequency, representing that such an occurrence sounds unmarked to Persian native speakers and Persian has a different word order rather than English in medical texts. It does not completely conform to the concept of Halliday’s theory with regard to markedness. This research  also illustrates that the properties of being pro-drop and having non-fixed word order distinguish Persian from English regarding the notion of markedness. In addition to language differences, theme markedness is closely related to some factors such as authors’/writers’ style differences, writing form types, text-clause relationship, emphasis, contrast, and specific genre. Since, the above mentioned factors in Persian and English effect theme markedness, they are regarded as their similarities, while language structure refers to their differences.
