Distributional semantics is a neo-constructuralist method that focuses on the use of words in real texts to understand the approximate meaning of a word, compared to other words. Since one of the goals of applying semantics in Quran, is to know the meaning of words according to practical context, the use of this method in Quran becomes important. In this research, in order to introduce the application of distributional semantics in the Qur'an, with the descriptive-analytical method, the steps of implementing, the challenges and solutions to overcome it, have been explained by examining a case study.The steps are: determining some words to compare with the main word, determining distributional features (surah, equivalent to document, and phrase), linguistic pre-processing of the Qur'anic text and removal of stopwords, forming context vector and co-occurrence matrix and weighting its elements, finding semantic similarity of words and its analysis. The most important challenges of using this method in Qur'an are the small volume of the Qur'anic text, the lack of suitable software for calculations in Quran, and the great difference in the length of surahs in the word-document pattern. Paying more attention to the basis of the distributional method (distributional hypothesis), not using this method for very low-frequency words, and comparing the results obtained from the word-document and word-phrase patterns are solutions to overcome some challenges. For the root-word Farah, it is obtained that the meaning from the Qur'anic context (close to the meaning of pride) is different from the meaning mentioned in dictionaries (joy).

In order to facilitate the release of floods from the dams and to prevent their damage or collapse, a structure called a spillway is used. Due to the natural and variable flow of the input to the reservoirs of the dams, there are times when the river inflow exceeds the consumption amount in the downstream agricultural lands. In these cases, excess water is discharged over the crest of the weir and flows towards the spillway, which causes high velocities. This high velocity creates low pressure areas on the spillway concrete surface, which can cause major damage to the spillway or even endanger the integrity of the dam structure. Therefore, the dam spillway must safely dissipate the kinetic energy. One of the types of weirs is the stepped spillway to facilitate the passage of the flow over the dams. One of the most obvious practical features of stepped spillways compared to other spillways is the considerable energy dissipation along the spillway. Care should be taken in designing and selecting the type of spillway to prevent potential erosion and reduce kinetic energy as the water flow passes over the spillway. One possible solution is to use a stepped spillway instead of a smooth spillway. In this study, a numeral model of a stepped spillway with different steps and slopes is used. For this purpose, ANSYS software is used for modeling free surface with application of k-ε turbulence model. In the present study, numerical simulation using the Volume of Fluid (VOF) model was used to investigate the mixing phenomenon of two phases of air and water of the free surface flow. The flow field was continued until the residuals reached 10^-7. Compared to simpler models such as Mixture, which operates solely on the basis of averaging the properties of two phases, the VOF model, is separating the phases and considering the effects of the interface. The VOF model, is capable of more accurate simulation of phenomena such as fluid mixing, turbulent flows, and heat transfer in multiphase flows. A number of hydraulic specifications which are considered in designing the stepped spillways are the pressure on the surface of the steps, velocity distribution and energy dissipation. The results from the numerical models were compared with experimental studies. They showed acceptable agreement with physical simulations. Results show that discharge and spillway slope increment reduces the amount of energy loss. In the spillway with 5 steps, for a discharge of 0.063 m³/s, the amount of energy dissipation at a slope of 26.6 degrees changes from 85 to 82% at a slope of 45 degrees, which shows a decrease of 3%. With the increase in discharge, the flow depth increases and reduces the effect of the roughness of the steps on the upper layers of the flow. Increasing the height of the steps increases the rate of energy dissipation and also increases the occurrence of negative pressures in stepped spillway. In this case, the contact surface between the main flow and the eddy currents increases. With the increase in the height of the steps, the dimensions of the rotating vortices also increase and cause a larger radius of rotation on the steps. The presence of these large rotating vortices separates the flow from the bottom of the steps and reduces the pressure on the surfaces. The number and dimensions of steps can alter the energy dissipation rate. Increase in the number of steps in a spillway with constant height, reduces the energy loss as the result of steps dimensions being shrunk

Certain compounds of plants such as essential oils, with insecticidal properties have been considered as alternatives to chemical pesticides for pest control. This study reports the fumigant toxicity of Citrus reticulata Blanco (Rutaceae) peel essential oils against stored-product insect pest, red flour beetle, Tribolium castaneum Herbst (Tenebrionidae) adults. Experiment was carried out at 27 ± 1 ^°C and 60 ± 5 % relative humidity in darkness. Experimental concentrations were 15, 22, 31, 45, and 63 μl/l air tested on adult (1-7 days old) insects after 24 and 48 h of exposure. Results indicated that essential oils from C. reticulata had fumigant tocxicity effects against this stored pest. LC50 values were 38.2 and 35.6 μl/l air at 24 and 48 h after exposure of T. castaneum adults respectively. The essential oils of Citrus reticulata fruit peels at the highest dose of 63 μl/l air caused 76.6 % and 79 % mortality of insects after 24 and 48 hours of exposure, respectively. Mortality of T. castaneum increased with both increase in concentration of C. reticulata oils as well as exposure time of treated insects. These results suggest the potencial of C. reticulata oil as a control agent against T. castaneum.

Introduction of modern technologies such as internet has had some downsides as well. The aim of the present study is to investigate some disadvantages of the integration of modern technology in organizations. The main body of the investigation will concentrate on the effect of different influential factors on cyber-loafing among the members of an organization. Regarding the literature on the subject matter, one of the leading factors that causes cyber-loafing is organizational justice. First, the influence of organizational justice, as the independent variable, on the distributional justice, procedural justice, and interactional justice is be discussed in details. Later on, the moderating role of perception of the organizational control in relation to organizational justice and cyber-loafing will be talked over. For testing the first hypothesis of the study, which focuses on the negative influence of organizational justice on cyber-loafing, the Lisrel software was used in through path analysis and structural equation modeling. The results obtained from 152 questionnaires distributed, among the employees of an automobile company, confirmed the credibility of the first hypothesis. Also the findings did not confirm the idea that the perception of organizational control plays a moderating role with regard to organizational justice and cyber-loafing.

From 2009 to 2012, 16 species of Curculionidae (Coleoptera) from the subfamily Lixinae were collected on 17 species of food plants in Iranian rangelands. Identified species belong to seven genera in the tribes Lixini and Cleonini. The host plants from which they were collected were in the families Asteraceae, Fabaceae, Apiaceae, Campanulaceae, Brassicaceae and Zygophyllaceae. Of the 16 species that we captured, two (Lixus subfarinosus Desbrochers, 1893 and Larinus remissus Faust, 1889) represent the first records from Iran. These new data also extend the known ranges of several species (Larinus fucatus Faust, 1894, Larinus grisescens Gyllenhal, 1835, Microlarinus rhinocylloides Hochhuth, 1847 and Bangasternus planifrons (Brulle, 1832) in Iran. The distribution of beetles and their associated host plants are presented and ecological notes on each species are provided.

  In recent years the importance of social capital as an intangible organizational asset has been of interest to those concerned with organizational and management issues. Positive levels of social capital are referred to, as a product of positive internal organizational social relations. The goal of this paper is the study of the relationship between the Iran Insurance employees’ understanding of organizational justice and social capital in the branches of the state of Gillan. Research method used is descriptive and of the Pyrson Correlative type. The statistical populationincludes all employees of Iran Insurance in the state of Gillan (altogether 492 people). Considering Cohen, Morgan and Krisay’s table, the sample size chosen was 220 people. The data collection tool used was a questioner which was field conducted. In order to asses levels of social capital the questioner designed by Gyshal and Nahpyt (1998), with 16 buoy was used; and to asses social justice levels a standard questioner with 19 buoys using the Leickert scale was employed. Validity of the research tool was based on the expert opinion of a group of experts. The social capital questioner’s stability, and the verification of the reported levels of organizational justice were approved by the use of Cron Bach’s 0/896 and 0/916 levels respectively. For data analysis the Pearson correlation test was used. Test results and the single-sample T-test showed that between the dependent research variable (social capital), and the independent research variable (organizational justice), and its’ different dimensions(Distributional, procedural, relational, and informational justice), a 99% positive correlation exists.

The spatial boundaries are not just important in the macro and international levels, but also are significant at the local, regional and national levels. They are significant in areas such as Mamasani County in which the social structure has the tribal nature. The spatial-identity boundaries are appeared due to the dominant tribal atmosphere. On this basis, the areas of culture, society and politics are overshadowed. Tribalism and socio-political boundaries in these areas consolidate each other through factors such as identity, geographic space; the creation of symbols and values; the emphasis on the notions of one's self and others; friendship, hostility and competition and the elections in local level (city council and village or parliament). This kind of solidarity plays an important role in stabilizing local- tribal and traditional political behavior on the one hand and perceptual and spatial boundaries on the other. This situation has consequences such as tribal divergence, cultural introspection and border demarcation. The current research is based on the question of what is the relationship between tribalism and socio-political boundaries in Mamasani. In explaining the research hypothesis, it seems that tribalism and socio-political boundaries mutually reinforce each other. The research is conducted using the descriptive-analytical method and the required data have been collected through library, documentary and field (observation) methods. The findings show that tribalism and socio-political boundaries had mutual effects on each other so that tribes were socialized and politicized during the reign of the Khans and after the fall of the Khans, tribal boundaries have also been influential in intensifying clannish attitudes.

A specimen of an ascomycetous fungus collected during a field trip was identified as Gymnoascus Baran. Soil samples collected from 0-20 cm depth were studied for isolation of fungi using a soil dilution plate method. Based on the morphological and molecular characters the specimens were identified as Gymnoascus reesii. Genomic DNA was extracted and a nuclear rDNA region, containing the internal transcribed spacers 1, 2 and 5.8S gene of rDNA (ITS) were amplified and PCR products were sequenced. Amplicon was purified, sequenced and submitted to the GenBank (Acc. No. JQ387570-71). The resulting sequence (600 bp) was submitted to a BLAST search to find most similar sequences in GenBank. The search results showed highest similarity of Iranian isolates to other isolates of G. reesii from GenBank. In the light of literature on ascomycetous fungi, Gymnoascus Baran is a new record for Iran mycoflora. The specimens are kept in fungal collection of the Department of Plant Protection, Razi University, Kermanshah, Iran.

The essential oils of aerial parts of three medicinal plants Artemisia khorassanica Podl., Rosmarinus officinalis L. and Mentha longifolia L. were isolated by hydrodistillation and investigated for their toxicity and repellency against Tribolium confusum Jacquelin du Val. at 27 ± 1 ºC and 60 ± 5% RH in darkness. The mortality of the adults increased with concentration from 185 to 1111 μl/l air and with exposure time from 9 to 24 h. A concentration of 185 μl/l air and exposure time of 24 h was sufficient to obtain nearly 100% kill of the adults in all of the three essential oils tested. At the highest concentration (1111 μl/l air) R. officinalis oil caused 15% mortality for an exposure time of 6-h. whilst, the oil of A. khorassanica resulted in 1% mortality at the same exposure time. The oil of A. khorassanica at 1111 μl/l air caused 81% mortality for 12-h exposure time. No significant differences were observed between the lethal time (LT₅₀) values at essential oil concentrations of 741 and 1111 μl/l air. For 24-h exposure time, the LC₅₀ values of A. khorassanica, R. officinalis and M. longifolia essential oils were estimated to be 22.45, 22.14 and 39.96 μl/l air respectively. Based on LC₅₀ values, adults of T. confusum showed similar susceptibility to the A. khorassanica and R. officinalis oils, but M. longifolia oil proved to be less toxic. In contrast to their low fumigant properties, the essential oil of M. longifolia had significantly higher repellency to T. confusum adults than did the other two.

In this paper, the effects of reflected waves of the facets on the internal optical intensity of semiconductor DFB lasers are investigated. The uniformity of optical intensity along the cavity length is evaluated with flatness parameter. The dependence of this parameter on coupling coefficient, reflectivity and grating phase at the facets is also studied. This investigation shows that in some structures reflected waves of the facets cause optical intensity along the cavity length to have more uniformed distribution than a DFB laser with anti-reflective facets. It is also shown that flatness parameter is very sensitive to grating phase .Thus it is necessary for designing a DFB laser to consider the effects of reflected wave and grating phase at both ends of cavity in order to increase the stability of the laser against SHB (Spatial Hole Burning) effect. The effects of reflectivity and grating phase on longitudinal distribution of photon and carrier density above threshold are investigated, too.

Aquaculture production is often accompanied by some stressors which undesirable effects on growth and physiological function. Music is one of the cases that could eliminate or reduce the effects of stressors. The purpose of this study was to determine the effect of Iranian traditional music on growth, reproduction and behaviour of zebra cichlid (Pseudotropheus zebra). Fish with an average weight 5.5  0.18 g were put under both music and silence treatment with the number of 2 fish/aquarium with 3 replicates for 4 weeks. Fish under music treatment were put twice a day and every 30 minutes under the Iranian traditional music. At the end of this period, suitable conditions for fish were created to spawning. The results showed no significant differences in growth parameters, but 50 percent of fish during the 2-week were spawned in music treatment. However, only 16.6 percent of fish under silent treatment were spawned. Of eggs and spawn time, significant differences were observed between two groups. When is music being played, the fish were found mainly along approach the speakers, while the distribution of fish treated silence was uniform. The results of present study showed that use of music can affect physiological function of fish, which have more tranquility and less stress on fish.

Environmental factors mainly temperature are believed to determine the distribution and population dynamics of Fusarium species in a natural ecosystem. Species may be restricted in their distribution by adaptation to specific sets of soil environmental conditions. Population dynamics of five Fusarium species representative of different climatic conditions were studied at three levels of temperature (13-18 / 19-24 / 25-30°C) and constant water potential (field capacity). Temperature had a significant influence on the population level of all test Fusarium species. Fusarium sambucinum showed noticeable reduction of population at warm temperatures. The population of F. solani and F. compaction were higher at high temperatures. The population of cosmopolitan species, F. equiseli showed little change at all experimental conditions, Fusarium acuminalum did not compete well with other species in this experiment, its population being low at all treatments.
