The Horn of Africa region in the east of this continent consists of four countries: Somalia, Ethiopia, Eritrea and Djibouti. Due to its geographical, geopolitical, strategic, geostrategic, geo-economics, etc. features, this region has always been of interest to regional and extra-regional actors. Each of the actors is trying to exert influence in this region and its countries and nations according to their national and strategic interests. Saudi Arabia is one of the active regional actors in the countries of the Horn of Africa. It seems that, in addition to its political, economic, military and security goals, this country pursues the promotion of its ideology and thinking, that is, Wahhabism. This research aims to investigate the ideological actions of Saudi Arabia in the countries of the Horn of Africa with the descriptive-analytical method and using library sources. The results show that Saudi Arabia is trying to promote Wahhabism among the Horn of Africa Muslims by spending financial expenses in the form of education, creating educational infrastructures, supporting Wahhabi groups, etc.

The aims of this study were to assess the effects of drought stress on peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) activities as well as free proline content and growth parameters of Pistacia khinjuk seedlings under drought stress. Therefore, the one-year seedlings of Pistacia khinjuk subjected to water stress (25%, 50%, 75%, and 100% field capacity) for 8 months in greenhouse condition. Results showed that drought stress decreased height, collar diameter, shoot dry weight and root dry weight of P. khinjuk seedlings. But it had different effects onantioxidant enzyme activities in root and shoot of P. khinjuk seedlings. Drought stress increased CAT activity in shoot and root of seedlings and its activity was higher in 25% field capacity (FC) than other treatments. Also, the POD enzyme activity increased in root and shoot of seedlings subjected to drought stress. The SOD activity was at the lowest level in 100% FC than other treatments. The results also showed that free proline accumulation was lower in well watered seedlings and increased under drought stress.

Aims: Drug abuse among college students continues as a major public-health concern. Theory-driven research is necessary to address and find causes. The current research investigates the utility of Theory of Planned Behavior (TPB) in designing and implementing a drug abuse educational prevention program among medical college students. Methods: This quasi-experimental study was conducted among 120 college students in two groups: experimental and control, who were randomly enrolled at the baseline survey. We used a questionnaire, which included three sections of background data (11 questions), knowledge about the side effects of drug abuse questionnaire (16 questions), and TPB-based questionnaire (20 questions). Educational planning was based on active learning with using group discussion, printed leaflet, and audio-visual CD. The participants were followed up after 2-month intervention. Data were analyzed by the SPSS software version 16 using appropriate statistical tests such as stepwise multiple logistic regressions and t-test. Findings: Almost 6.7% of the participants had a history of drug abuse. The three predictors of 1) attitude, 2) subjective norms, and 3) perceived behavioral control accounted for 48 % of the variation in the outcome measure of the intention to drug abuse. There was a significant improvement in average response for knowledge about the side effects of drug abuse and TPB variables among the students who were under intervention (P < 0.05). Conclusions: Designing intervention to reduce positive attitude and subjective norms toward drug abuse among college students could be useful to substance abuse prevention.

Mystically language is one of the most important tools for expressing the mystical meanings. The language which the contemporary arab poets have well benefited from it. Abdol- Suboor is one of those poets who has met with the great heritage of Iranian Sufism. According to the poet, Attar’s and Rumi's works constitute part of his poetry. His ode “Remembrance of suffi bishr al hafi”, has been affected by the (Manteq at-tayr) of Attār, which is the story of allegorical and symbolic move toward self-perfection. He uses the mask method in this ode, so that, the ode is in motion, in an existential space towards the “pantheism” and “perfect man” and, finally, the form remains open without being finished. This research has used the method of comparative literature. By reviewing the similarities of the two works, it indicates that the ode “Remembrance of suffi Bishr al Hafi” has used the story theme of travel truth in the Attār's (Manteq at-tayr)

The quality of relation between religiosity and electoral behavior as the research main question derives observation of the paradoxical result of some researches about the relation of these two variables. For deeper understanding of the relation between these two variables, the scale of religiosity, and electoral behavior in two levels of voting attitude and voting participation were analyzed. According to the review of the theoretical and experimental literature, two hypotheses were proposed as fallows: increasing in the scale of the religiosity leads to higher voting participation and voting to Osulgarayan, and decreasing in the scale of religiosity leads to lower voting participation and voting to Eslahtalaban. The research method was survey with questionair and three observational questions. The statistical population of the current research was Tarbait Modares University students. Through nonprobability sampling, 376 students were purposefully selected as sample size. Some descriptive statistics and analytical techniques were used (mean, frequency distribution cross tables, T test, linear and logistic regression). According to the findings, the scale of religiosity has a significant effect on electoral behavior (voting attitude and voting participation), such that increasing in the scale of religiosity leads to voting toosulgarayan and increasing in the voting participation, while decreasing in the scale of religiosity leads to voting to Eslahtalaban and decreasing in the voting participation.

The cypress family, Cupressaceae, has a global dispersion. Currently, endophytic microorganisms from plants are being investigated for their diversity and bioactivities. Here, we aimed at exploration and characterization of cultivable endophytic fungi from foliar tissues of Cupressaceae, i.e. Cupressus arizonica, C. sempervirens var. cereiformis, C. sempervirens var. fastigiata, Juniperus excelsa, Juniperus sp. and Thuja orientalis. Asymptomatic fresh foliar tissues, collected from mature healthy plants, were sterilized and the inner layers were plated on culture media at 26-28 °C for 2-12 weeks, until fungal colonies emerged and were purified. Endophytic Penicillia i.e. Penicillium aurantiogriseum, P. chrysogenum, P. commune, P. echinulatum, P. expansum and P. viridicatum were the dominant fungi recovered. Results indicated that both host plant and geographical location of sampling affected the biodiversity and bioactivity of endophytic Penicillia. Results also indicated that those endophytic Penicillia had significant bioactivities. According to our results, both intra-and extra-cellular secondary metabolites from all isolated Penicillia had significant cytotoxic and antifungal effects against the model fungus Pyricularia oryzae and cypress fungal phytopathogens Diplodia seriata, Phaeobotryon cupressi and Spencermartinsia viticola. Further studies indicated the significant antimicrobial bioactivities of superior Penicillia against model bacteria. Altogether, this study highlights, for the first time, the biodiversity of endophytic Penicillia from Cupressaceae plants and documents their significance for agrochemical/drug discovery and for plant disease biocontrol.

This paper studies the conditions of production and understanding of the meaning of “Leqa-on Fi LazateRahil” by Nasrin Edris, Lebanese author. The story of “Leqa..” can be studied sustainability from a new semantic point of view, which includes the photographer and the fighters’ active discourses. Hamzah follows the program; his skill in the photography creates the main character in the action. The Commander has an important role in the acquisition of Hamzah’s emotional ability. In the second discourse, the fighters enter into action after the contract and obtaining the ability. Therefore, the main actions are performed simultaneously; the fighters fight and Hamzah takes photos. All procedures are performed respectively. The dominant discourse is intelligent, but emotional processes, especially photographer part, play an important role in the story forming. The aim of this research was to study the semantic process and narrative traits of the “Leqa..” story in order to achieve the main meaning functions and details. Also the effect of emotion on the meaning process has been investigated

Due to its nature, water resources, in addition to giving life to a land and its creatures, can be the source of differences between countries and nations with common resources and cause great losses. In this regard, a new field of research called hydro politics has been created that surveys these issues. Considering the climate situation of the Middle East and the widespread limitation of water resources in this region, the purpose of this study is to investigate the hydro political situation of Iran's joint watersheds with neighbors with emphasis on the Tigris and Euphrates, especially the Arvandrud River. Using the descriptive-analytical method, first, the resources were reviewed systematically, and then the situation of water resources in the area was identified and studied using spatial analysis. Surveys were conducted on three large scales in the Tigris and Euphrates basins, the middle scale in the Karkheh and Karun basins, and the local scale in the Arvandrud River joint area. Studies have shown that the hydro political situation in the region will become tenser with the control of water by upstream countries and due to the very high population growth and water consumption in Iraq. Also, due to Iraq's limited access to open waters and its very small and unsuitable coastline for maritime transport, there is a potential for tension in the region in the future

The main purpose of this research is to develope a model for identification of organizational skepticism and its concepts. Grounded theory method applied for this research. Available non probable sampling method has been used and structural interviews have been performed with employees of private companies. Sampling continued until saturation point in answers has been reached (24 interviews). After using this method, including open and axial and selecting coding, causes and consequences of organizational skepticism have been identified. causes have been investigated in two fields. First, organizational management (management style and personal characteristics of manager and human resource management process and activities and Performance evaluation system) and Second, Organization related fields (organizational cynicism, organizational justice and organizational climate). Consequences of organizational skepticism also have been investigated in two fields of individual and organizational. Short-term effects of individual variables such as organizational indifference, motivational, lack of willingness to participate, job stress and burnout and long-term effects of individual variables such as low productivity of individual, corporate sabotage, poor quality of external engagement, life satisfaction and organizational frustration were classified. These consequences have also led to a long-term impact on organizational outcomes such as low productivity of the organization.

Entering into the Arabic language and literature in the early Islamic centuries, Iranian culture generally turned to become a position of Arabic culture and common among the people in the 4^th century (A.H.). This culture has been transferred though the language tool; therefore, it has influenced on the Iranian authors who used to write in Arabic.  Abu-Hahyyan Al-Tawhidi is one of  the greatest scientists in the Islamic world in the 4^th  century (A.D.) whose  works have Iranian vein. In his book, Titled  Al-Amtaa  Wal-Muanassa, there are almost100 pension load words, among which 20 words, have appeared  for the first time in his work, 21 words have been taken from the Ignorance Age introduced into the Arabic language, and 57 words are loan words borrowed from the Islamic and Arabic eras. The Persian loan words mainly include the names of food stuff, birds, animals, and mechanic herbs. The names of flowers, musical instruments, plays, building tools, etc. have rarely been used in this books. Since, the Persian loanwords are meaningful by themselves; hence, the goal of this study is to assign the cultural meaning/concept of Persian words, which have conveyed in to Arabic Language.  As such, through knowing the Semitics of words, the kind of influencing culture can be easily specified.

The effect of dietary composition and starvation on growth and plasma metabolites in rainbow trout of 14 g average initial weight was investigated. A group of 240 trout juveniles were distributed in 12 of 150 L tanks. The experiment was performed in a 2*2 factorial design with 2 lipid levels (10 and 18%) and 2 feeding conditions (feeding and starvation) with 4 treatments each with 3 replicates. The fish were fed on diet 1 (lipid 10%, carbohydrate 29%) and diet 2 (lipid 18%, carbohydrate 19%) with the same protein level (47%) and energy. The juveniles were fed to apparent satiation for 3 weeks, followed by starving for 2 weeks and then refed for 3 weeks. The biometery and plasma biochemical parameters were analysed in the day of 21 (end of 3 weeks feeding), 35 (after 2 weeks starvation) and 60 (end of 3 weeks refeeding). Based on the result, the best growth performance in the fish occurred in diet with 10% lipid in control group (feeding group) and no compensatory growth occurred in this treatmennt after 2 weeks starvation. Moreover, the result of body composition showed the starvation and diet composition had more effect on body lipid than body protein and body lipid content decreased by starvation. The starvation and diet composition did not have any significant effect on cholesterol and triglyceride, but they induced decreasing plasma glucose level in the trout.

Aims: Cement industry is considered as one of the major consuming energies, producing large amounts of environmental contaminants. The aim of this study was to examine the extent of metals Cadmium (Cd), Zinc (Zn), Lead (Pb), and Manganese (Mn) in the soil and leaves of planted around the cement factory in Pinus eldarica, Ulmus umbraculifera, and Quercus brantii naturally grown there.
Materials and Methods: In the present experimental study, to perform this, the level of elements was examined in the leaves as well as depths of 0-10 and 10-20cm of soil across the three studied species using atomic absorption device. The extent of elements sequestrated in the factory’s electro filter was also measured. One-way ANOVA test, Duncan’s test, and SPSS 20 software were used for Statistical analysis.
Findings: Cadmium was sequestrated in the electro filter was almost close to the level of cadmium in the leaf and soil samples. The level of lead, zinc, and manganese in the electro filter of the factory were higher than the extent of sequestration of these three elements in the leaf of three tree species and the soil below them. Across the three species, with increased depth of soil, the extent of lead sequestration declined. Pinus eldarica had the minimum extent of sequestration for the four studied elements both in the soil and leaf across the three studied species.
Conclusion: Quercus brantii and Ulmus umbraculifera have a greater potential in sequestration of heavy metals in comparison with Pinus eldarica.
