The current research aims to investigate the universality of the language by examining the perception of Persian learners in recognition of subject position according to the theory of input processing and the principle of the first noun from this theory. The first noun principle indicates that language learners consider the noun or pronoun that comes at the beginning of the sentence as the subject of the sentence.The participants in this research are 70 Persian language learners at elementary (23 participants), intermediate (23 participants) and advanced (24 participants) levels in the Persian language learning center of Al-Zahra University. Using Friedman et al.'s (2004) executive method, this study has examined the principle of the first noun as a predictable path in the education of Persian learners. In this direction, a test has been designed on Google Forms, and Persian learners have participated in two different implementations of this test in a time interval of 5 months. In both of its implementations, this test included 15 sentences that the language learners had to connect to the related pictures after hearing the sentences. In order to characterize the perception of the participants from the position of the subject, 8 sentences in the second sentence were put into the passive form. The results of this study have shown that the change of sentences in the second implementation of the test caused an increase in errors in the response rate of language learners and this was reported higher in elementary language learners than in other groups.

Most of the common oil and gas fields are located in the Persian Gulf, which is one of the shallowest seas in the world. The region of West Asia and the Persian Gulf is experiencing countless geopolitical tensions. Historically, these common oil fields are a source of conflict and tension that has led to wars. Iran and Iraq have 15 common oil fields. The present study, entitled Analysis of the geopolitical consequences of the shared oil resources between Iran and Iraq, seeks to answer the question of what role the shared oil resources of Iran and Iraq play in the relations between the two countries. Also, descriptive-analytical method and Dimetal technique have been used to investigate the title of the research. The findings of the research show that variables such as regional competition, unilateral development of common oil fields, close economic cooperation, regional differences, Iran's economic growth and the reduction of the effect of sanctions, different business partners, differences in attracting foreign investment, Iran's inability to invest, geopolitical convergence in the Strait of Hormuz, joint ventures, instability in economic diplomacy, etc. in the region indicate high interaction and strong systemic connection with other variables. Based on the analysis, it seems that it is necessary for Iran to develop relations with Iraq with a detailed analysis of the current situation and according to Kargosha's predictions about the future, while trying to maintain its share and wealth in common reservoirs and foreign investment in the oil industry in order to transform potential threats into new opportunities and provide maximum benefits by creating cooperation.

Background: Asthma is the main reason of disability, health resource exploitation and low quality of life for those who are affected. It is estimated that nearly 300 million people in the world are suffering from asthma. Studies have identified 18 genomic regions and more than 100 genes associated with asthma. Among these candidate genes, IL-17F plays a very interesting role in asthma. This study was conducted to predict the conformational and functional impact of asthma-associated IL-17F polymorphisms on protein product of the corresponding gene using Phyre2, PolyPhen2 and SIFT softwares. Methods: In the present study, 10 significant missense SNPs (rs763780, rs144576902, rs11465553, rs368500268, rs141798304, rs2397084, rs146083682, rs200163061, rs376671742, and rs373228601) were taken from Ensembl Genome Browser database. Polymorphism-induced protein structural changes were predicted using Protein Homology analogY Recognition Engine V2.0 (PHYRE2) program. The possible impact of an amino acid substitution on the function of protein was analyzed using PolyPhen-2 (Polymorphism Phenotyping Version2) and SIFT (Sorting Intolerant From Tolerant) tools. Results: The analysis revealed mutant proteins having structural changes in the number of atoms, H-bonds, turns and helices. While wild copy has 82 H-bonds, 5 helices and 20 turns, the mutant types show considerable changes. At functional level also, substantial changes were observed between the wild protein and the mutant one. Conclusion: A single nucleotide polymorphism in the gene sequence can lead to the substantial structural and functional variations in the protein product of the gene, a process that may account for etiology of a number of complex diseases including asthma.

The potato tuber moth (PTM), Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae), is an important pest of potato and other solanaceous plants. It is cosmopolite and oligophage that exists in most countries where potatoes are grown. Because of chemical treatment adverse effects, there is a necessity to find safe alternatives to synthetic insecticides. So, medicinal plants are promising since they are safe, inexpensive and effective. In this direction, potato tubers were dipped in 1 ml of 5% methanolic extracts of fumitory, licorice, lavender and oregano. The percentage of first larval penetration to tubers and oviposition-preference of mentioned medicinal plants was investigated on PTM. Subsequently, fumigant toxicity of essential oils of basil, european pennyroyal, lavender, mint and savory were investigated on P. operculella. Treated potato tubers by methanolic extract of lavender elicited the lowest percentage (19.3) of first larval penetration. Studying of oviposition-preference demonstrated that the largest number of eggs were laid on control and fumitory with 28 and 10 eggs after three days, respectively. Probit analysis of essential oils showed that the most effective oil was savory which exhibited LC₅₀ value on adults of PTM equivalent to 0.048 µL/L air.

The effect of various host plants including chickpea (varieties Arman, Hashem, Azad and Binivich), common bean (variety Khomein), white kidney bean (variety Dehghan), red kidney bean (variety Goli), cowpea (variety Mashhad), and tomato (variety Meshkin) on the reproductive performance and growth indices of the cotton bollworm, Helicoverpa armigera (Hübner) was determined under laboratory conditions (25 ± 1°C, 65 ± 5% RH and a 16:8 h light:dark photoperiod). The highest rate of gross fecundity, gross fertility, net fecundity, net fertility, mean daily eggs and mean daily fertile eggs were observed on chickpea Arman (2947.8 ± 7.8, 2933.0 ± 7.8, 2404.2 ± 7.1, 2392.2 ± 7.1, 170.9 ± 0.4, and 170.1 ± 0.4 eggs female^-1, respectively), whereas the lowest values of these parameters were on tomato Meshkin (847.5 ± 9.2, 673.8 ± 7.3, 225.5 ± 2.6, 179.3 ± 2.1, 67.9 ± 0.7 and 54.3 ± 0.5 eggs female^-1, respectively). The development index of overall immature stages varied from 1.10 to 1.57, with the minimum on tomato Meshkin and the maximum on chickpea Arman. Also, the fitness and standardized insect-growth indices were highest (0.349 ± 0.009 and 0.058 ± 0.001 gr day^-1) and lowest (0.052 ± 0.001 and 0.013 ± 0.000 gr day^-1) on chickpea Arman and tomato Meshkin, respectively. The Weibull model sufficiently described the shape of the survivorship curve of adult H. armigera from life-table data. A significant fit was obtained with the Weibull model for H. armigera in all experimental host plants. The results of reproductive performance, growth indices and the cluster analysis showed that tomato Meshkin was partially resistant to H. armigera.

The Bird cherry-oat aphid, Rhopalosiphum padi (L.) is a serious threat to several cereal crops. Host-plant resistance to this aphid could be especially valuable in cereal crops pest management. Therefore, we evaluated the development, survivorship, reproduction and population growth parameters of R. padi as resistance indices among six wheat cultivars, including Gaskojen, Tajan, Falat, Saysonz, Kras and Sardari at 25 °C under laboratory conditions. The development time and fecundity of aphid differed significantly among the tested wheat cultivars. The r_m values were highest for aphids reared on Sardari and lowest on Gaskojen and intermediate on Tajan, Saysonz and Kras cultivars. Aphid showed the longest development time and the lowest fecundity, reflecting in the lowest r_m value on Gaskojen cultivar. Consequently, Gaskojen showed more positive characteristics and was relatively not susceptible cultivar that could be considered for planning a comprehensive IPM program of R. padi.

Background: Trichomoniasis is the most common nonviral sexually transmitted human disease that is caused by protozoan Trichomonas vaginalis. Metronidazole is the selective drug in trichomoniasis treatment. However, the reported cases show an increasing trend of drug resistance. This study aimed to evaluate the effect of mango and blueberry extracts on T. vaginalis.
Materials and Methods: T. vaginalis was cultured axenically in TYM (Trypticase Yeast Extract) medium supplemented with 10% bovine serum. The effect of mango and blueberry extracts at 50, 100, 200, 400, 800 and 1000 μg.mL^-1 on T. vaginalis was studied after 24 and 48 hours. The final numbers of parasite with a hemocytometer and Trypan blue were recorded. Then the value of IC₅₀ [Half maximal inhibitory concentration] and the lethal percent were calculated. In the present study, the metronidazole was used as positive control. The IC₅₀ value of metronidazole and tinidazole were calculated in the concentrations of 0.02, 0.04, 0.08, 0.16 and 0.32 μg.mL^-1.
Results: The final results confirmed the significant effect of all mango and blueberry extracts concentrations on the reduction of parasite numbers (P-value<0.05(. The extract concentrations of 1000 μg.mL^-1 had the most significant effect on T. vaginalis growth inhibition after 24 hours. The IC₅₀ values of mango and blueberry extracts, metronidazole, and tinidazole were calculated as 118.3, 60.74, 0.042 and 0.02 μg.ml^-1 respectively.
Conclusion: Based on the obtained results, the different concentrations of mango and blueberry extracts have significant anti  Trichomonas vaginalis activities. It is suggested  carrying out further studies on suitable animal models.

Rosy apple aphid, Dysaphis plantaginea (Passerini), with worldwide distribution is an important pest of apple orchards. Host plant resistance is an essential component of integrated management of this insect pest. We investigated the resistance of seven apple cultivars, Malus domestica (Borkhausen), namely Granny Smith, Starkrimson, Golden Smoothee, Red Delicious, Golden Delicious, Boshghabi, and Shaki to rosy apple aphid under field and greenhouse conditions. The damage level by rosy apple aphid was significantly different among the tested cultivars precisely three weeks after infestation in both field and greenhouse conditions. The least leaf curling was observed on Shaki, while the most deformation was detected on Golden Delicious. There was positive correlation between damage in greenhouse and field studies. In addition, the lowest and highest numbers of aphids were observed on Shaki and Golden Delicious, respectively. Consequently, our results demonstrated that among the cultivars tested the Shaki cultivar is moderately resistant to rosy apple aphid and has the potential to be used in the integrated management of this aphid.

The subject of the grammatical category VID in Russian language and its equivalent “verbal representation” in Persian Language is of special importance. Each of these languages, as per its own structural and linguistic features, employs specific media of expression. Actually, the category of aspect does exist in every language. In fact, all concepts and meanings originate from within the human mind that, in order to manifest such concepts in the form of language, utilizes plentiful of linguistic structures specific to its own implicit and explicit attributes.  That is why linguists believe that such structure does exist generally in all languages of the world with the only difference in their medium of expression (grammatical and non-grammatical) and the concept and meaning they convey. The results of the comparative studies conducted in the field of “verbal representation” in Persian and Russian languages reveal that the major difference is in their method of expression. The current research is an attempt to study the subject of verbal representation in Russian and Persian languages through the practice of imperfect verbal representation.

During a survey on the identification of plant-parasitic nematodes associated with walnut in Sanandej region (Kurdistan province, western Iran), a population of Paratylenchus labiosus was collected and identified morphologically. Description, illustrations and morphometrics of the species are given and comparisons are made between it and some related species. Paratylenchus labiosus comes more close to three species namely P. similis, P. tateae and P. italiensis in having certain diagnostic characters such as short stylet less than 18 µm long, concave-conoid head with prominent submedian lobes and tail ending to an acute to finely rounded terminus. However, P. labiosus differs from them in having a spermatheca full of sperm cells and presence of males. Different modes of reproduction (parthenogenesis or amphimixis) may be observed in different populations of some species in this genus, but somewhat unique reproduction behavior of P. labiosus could be considered as a diagnostic character for separation of it from the three closely related species.

The eggs and larvae of the Indian meal moth, Plodia interpunctella (Hübner), are widely used in mass rearing of parasitoids and predators. Feeding indices and some biological parameters of P. interpunctella were studied on bran of different wheat cultivars ('Back-cross Roshan', 'Khooshe Pishgam', 'Khoshki line 9', 'Arg', 'Alvand', 'Pishtaz', 'WS-89-2', 'Sepahan' and 'Bam') when incorporated into artificial diets under laboratory conditions (25 ± 1 ºC, 65 ± 5% R.H., and a 16:8 h light-dark photoperiod). The efficiency of conversion of ingested food was highest on 'Back-cross Roshan' (98.79 ± 8.48%) and lowest on 'Pishtaz' (64.56 ± 9.66%). The highest and lowest percentage of mortality of P. interpunctella larvae were on 'Pishtaz' (56%) and 'Back cross Roshan' (12%). Our results showed that larval growth index was highest on 'Khoshki line 9' (5.81) and lowest on 'Pishtaz' (3.33). Moreover, the highest daily and total fecundity were detected in moths that were reared on 'Back-cross Roshan' (37.6 ± 0.93 and 177.3 ± 1.61 eggs, respectively). The results demonstrated that, among different wheat cultivars tested, 'Back-cross Roshan' was the most suitable cultivar for P. interpunctella rearing in order to optimize the mass production of natural enemies.

The Calling myths have prominent role to deepen and enrich the literature of different nations including Arabs Iranian myth, "Zoroaster", one of the myths That there is not often in classical Arabic poetry. But some contemporary Arab poets inspired by Friedrich Nietzsche (1844 - 1900), German poet and philosopher, In the framework of "Qna" and the mask of the Zoroastrian myth, Seeking element for social and political struggles In the wake of people with superhuman slogan Thereby uprising Against the evil tyranny and corruption of contemporary oppressors .the Purpose of this article is a comparative study of the Zoroastrian myth In ancient and contemporary Arab poetry To show what is the symbolic thought of this Arabic poets About this archetype? And basically for what purpose, each of these poets has been used of this Myth in their poem? Achievement of this study that is written Based on the Descriptive analysis method shows that in the old Arab literature, it is very hard to find a Poet that mentioned the myth of "Zarathustra" in his poem. And only observed a few references to the Magi and the religion of Pre-Islamic Persian in The poetry of this period. In contrast, in contemporary Arabic literature, Zoroaster has come in the formation of a national savior in to the form of a political ambassador that emancipated the Contemporary human of the Political Pains and suffering.
