Writing assessment literacy(WAL) for second or foreign language (L2) teachers, which refers to teachers’ knowledge, conceptions, and practice of writing assessment in L2 contexts, has lately received attention from scholars. Although there has been significant debate about the impact of contextual and conceptual factors on teachers’ assessment literacy, studies focusing on how such factors influence teachers’ WAL are lacking. The purpose of this qualitative study was to explore the way Iranian English writing teachers' conception of assessment, and macro, meso, and micro contextual variables impact their writing assessment practice. It also looked at how writing teachers make assessment decisions in order to negotiate and find a compromise when their assessment views and beliefs diverge from the assessment policies in their local contexts. The data was collected through semi-structured interviews with ten in-service l2 writing teachers in Iran. The findings show that participants had positive conceptions about formative writing assessments but they stated that they mostly used summative assessment in writing classes. Macro level contextual factors turned out to mostly impacted teachers’ writing assessment practices and conceptions. The results underscored the role of school and work experience in shaping and changing writing assessment conceptions. The findings of this study contribute to our current understanding of WAL development and provision of more efficient assessment training for language teachers in teacher education programs.

Tense plays an important and determining role in human verbal communication; therefore, one of the things that should be addressed in language teaching is the discussion of time and ways to recognize it. Considering the role and importance of grammatical tense recognition in language learning and the lack of related research regarding Persian language learning, the purpose of the present research is to investigate the role of available cues in sentences to recognize grammatical tense by Chinese Persian learners of beginner and advanced levels; For this purpose, 49 Persian learners of Chinese language were selected by available sampling method and divided into two groups of Chinese language beginner (26) and advanced (23) based on the level determination test. The instruments used in this research were two tests in two stages; In the first stage, by using the sentence recognition test, the subjects marked the time of the sentences they heard in the answer sheet, and in the second stage, the same test was performed; with the difference that in this test, the sentences did not have time adverbs. The results of this research showed that the subjects of the beginner Chinese language meaningfully used lexical clues when recognizing the time of the sentence, and the subjects of the advanced level simultaneously used two lexical clues and present tense. Regarding the role of gender, the results showed that there is no significant relationship between gender and the ability to understand sentence time. The results of this research can be useful for language learners, teachers, and producers of educational content and also for test designers.

Narratives have many layers of meaning. These semantic layers encompass intra-discourse systems and represent their changes and developments. Eric Landowski sought to achieve the missing links of meaning in narrative contexts by designing semantic systems. Contexts that show discourse and narrative actions. According to Landowski's four semantic systems, which are emphasized in this study, namely, the system of "abyss and spinning ", it is possible to decipher the signs in the text and the relationship between these signs and each other and the author's worldview. The present study, based on a descriptive-analytical approach, seeks to achieve subtle and coherent layers of meaning in the novel Symphony of the Dead by Abbas Maroufi. Given the mastery of the author in creating works with the fluid flow of the mind in this study, we aim to show how the subjects are intertwined with the world around them and as they are opening up, their emotions and to some extent their destiny to another spreads. Also, by analyzing the abyss system, we come to the point that the subject cannot shape his own destiny alone, and after he finds himself incapable, he is forced to accept what luck has for him.

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.

Soybean, Glycine max (L.) Merr is one of the most important oilseed plants in the world and Phythophthora root and crown rot is a significant limiting factor for its planting. In the present study the antagonistic effect of 12 Trichoderma spp. in vitro and these Trichoderma spp. in combination with Bradyrhizobium japonicum in vivo on Phytophthora sojae and soybean growth were tested. In laboratory tests the effects of Trichoderma isolates were studied in dual culture, volatile compounds and culture filtrate metabolites. The most hyphal growth inhibitions were obtained using T. virens, T. orientals and T. brevicompactum in dual culture tests and T. atroviride in volatile compounds test. The effects of Trichoderma culture filtrates on P. sojae hyphal growth were studied at six concentrations in CMA medium and the results showed that culture filtrates of all species inhibited the hyphal growth and that different concentrations had different inhibitory effects. The most inhibition was obtained by T. virens and T. brevicampactom culture filtrates. The greenhouse tests were carried out as two experiments. In the first experiment the effects of coated seeds with Trichoderma isolates and B. japonicum, alone and in combinations, on control of P. sojae and in the second experiment the effect of these two biocontrol agents on soybean growth, alone and in combinations, were assayed. In the first experiment, germination percentage, damping-off, seedling vigour index (SVI) and disease severity were measured and results showed that T. brevicompactum as alone and in combinations, was the most effective species. In the second experiment, coated seeds with Trichoderma isolates and B. japonicum, as alone and in combinations, significantly promoted the growth of treated seeds and the most effective species were T. orientals, T. brevicompactum and T. spirale. Hence, results indicate that T. brevicompactum, as the second most common species after T. harzianum in Iran, was the most successful species applied individually and in combinations with B. japonicum to act as biocontrol agent for P. sojae and was also able to promote plant growth.

Introduction: As one of the oldest and the most dynamic branches of political geography, Electoral geography has experienced ups and downs more than other branches of political geography. The objective ontology of the phenomenon of vote and its spatial distribution have linked this branch to spatial approach so that a large proportion of works in the area of Electoral geography have been written based on this approach. With the fall of positivism, the researches of Electoral geography also decreased. On the other hand, domination of descriptive, case, and applied studies without a robust theoretical and philosophical basis on theoretical and basic writings, is the main deficiency of Electoral geography in International and Iranian level. The aim of the present theoretical-fundamental study was to explain the dominant theoretical approaches in Electoral geography.
Conclusion: The Electoral geography can be explored in five theoretical approaches. The first approach is the traditional approach that deals with the spatial patterns of voting in the form of a regional school and human-environment relations. The second one is a spatial-behavioral approach that examines the voting behavior according to the measurement and analysis of key spatial variables based on the spatial school. The third approach is a radical approach that base on radical geography school deals with the theoretical articulation and revealing mechanisms that form Electoral processes. The fourth approach is a location-based approach that focuses on the impact of geographic-historical context on electoral behavior on the basis of the humanistic geography school and structuration theory. And, the fifth approach is a critical approach that criticizes the current approaches to the study of electoral geography and the presesentation of alternative readerships of electoral geography based on schools such as feminism, post-structuralism, and post-modernism.

In this paper, results of the study on heavy metals solubility behavior of Ni-Cd filter cakes in Iranian Zinc Mine Development Company (IZMDC) plants are investigated. The effects of pH, temperature, liquid/solid ratio and contact time on the release of heavy metals (Zn, Cd, Ni and Pb) into water media was examined. Also, “Extraction procedure tests” approved by EPA were applied to the residues. Moreover, statistical data analysis was performed and the most important parameters for dissolution of Zn, Cd, Ni and Pb were found to be the pH and L/S.. The concentration of Cd and Pb in the extracts obtained from filter cakes by applying EPA extraction procedures at pH 5 are over 1.0 and 5.0 mg/L, which are toxicity limits, respectively. The concentrations of other metals in the solution are above the limits given by various quality standards for surface water.

This research investigates the vegetation of 4600 ha of Polour semi-steppe rangelands in relation to edaphic and physiographical parameters in Mazandaran province. For this purpose, 23 land units were selected from overlaying slope, aspect and elevation maps using geographic information system (GIS). Within each unit, 3 parallel transects with 100 m length, each containing 10 quadrates (according to vegetation variation) were established. Sampling method was Random systematic. Measured soil properties included texture, organic matter, pH, electrical conductivity, nitrogen, phosphor, and litter. Soil and plant data were analyzed with redundancy analysis and SHAZAM 10 package. RDA analysis suggesting that there is a relatively high correspondence between vegetation and environmental factors that explain 93% of the total variance in data set. RDA results showed that soil slope, aspect, soil texture, acidity, phosphor, and litter were the major environmental factors responsible for variations in vegetation patterns. Furthermore, results also showed that for F .ovina and P .bulbosa, acidity and nitrogen, for A .gossypinus, organic matter and salinity and for D .glomerata, nitrogen have the most important role in plant presence and absence probability.

The pattern in the last few decades, especially in countries and regions located in the desert of the earth are considered, as a reflection of climate change. A situation that threatens security, stability and development in many areas due to reduced rainfall and water scarcity. Iran has also been strongly influenced by these events and changes in its attitude towards its geographical position during the last decade and half. Southeastern Iran with center (Sistan and Baluchestan Province) which has been a region with low rainfall, daring several periods of time due to climate to the point that it has become one of the migrating provinces of the country. An event that has itself given rise to emerging security issues and challenges, especially in border areas
The present article is based on the hypothesis that the decrease in rainfall and threat of water resources has led to the emigration of the province. The methodology of the present study is descriptive-analytical and the required data and information are collected through the meteorological organization and the national statistics center and then using standard rainfall (SPI) and normal rainfall (PNPI) percentage investigate and analyze the spatial distribution of drought (period, 1996-2011) and its impact on the migration of residents of the strategic area. The results show that the occurrence of severe or very severe droughts in a region has negative reflections on the livelihood of residents in the region, which with the attitude of the people of the province to dependence on limited water resources and traditional agriculture and the lack of land management policies and hydro-political relations between Iran and Afghanistan have led to an increase in the crisis in the east of the country, and the people of this province have inevitably migrated to neighboring provinces and other parts of the country to provide better living conditions.

In the last decade, there has been more attention towards the assessment and improvement of construction  phase embodied energy. In addition to buildings maintenance energy, large amounts of energies are consumed in construction process which is called embodied energy. This research results from recording all types of energies used in construction phase and presenting a numerical calculation method to assess the embodied energy of area unit and also decreasing this energy to its lowest possible limit. In order to achieve the minimum embodied energy, three energy consuming phases are calculated for 1400 square meter case study; which are material embodied energy, transportation energy and erection and on-site energy. Deviation of total embodied energy for the area shows 795.14 GJ/M2 as embodied energy. This digit is a reliable benchmark for comparing these three energy consuming phases and also comparing this construction system with other ones. Total embodied energy it the result of all three parts. But analysis of them shows that it's necessary to substitute some materials with more optimized ones. The result of this substitution decreased the embodied energy to 12.75 GJ/M2 and which is about 1.6% of the first measured embodied energy.

Soil erosion is an abstruse phenomenon which contains segregation and transmission of soil particles and runoff from rainfall and infiltration. Runoff and sediment generation was compared using rainfall simulator in grassland (St. parviflora-Br. tomentellus) and shrubland (As. parrowianus-As. gossipinus). For this purpose, vegetation map was supplied for two vegetation types four main aspects and two slope classes (12%-20% and 20%-40%)  and corresponding work units were accordingly determined Three points were selected in each unit and rainfall simulator set inside them through a randomized pattern. The intensity of rainfall simulation was 1.6 mm min^-1 with 10 minute duration and then runoff and sediment were measured. One soil sample (depth of 0–40 cm) was collected and assessed for pH, OM, EC, P, K, Ca, Mg and texture in the laboratory at the vicinity of the study area. The results of Duncan test and multiple regressions showed that grassland had more runoff and sediment than shrubland, but initial time of runoff in grassland was less than shrubland. Also aspects, slopes and soil characteristics (EC, Ca, Clay, P) had significant effects on runoff, sediment and initial time and they had linear correlation with runoff and sediment.

One of the important technical obstacles in the study of many filamentous fungi is the development of efficient transformation system. Transformation of filamentous fungi is difficult because they have a cell wall and for most frequently used approaches preparing of protoplast is necessary. Protoplast preparation is batch-dependent and often frustrating work. In this study, a modified method was introduced for gene transfer to the plant pathogenic fungus, Fusarium graminearum, the major causal agent of Fusarium Head Blight disease in small grains. This protocol was based on protoplast-PEG method. Age of mycelia, enzymes exposure time and mycelium/enzyme ratio were optimized for the purpose of protoplast preparation. The outcome showed that the best result for protoplast preparation was obtained when 1.5 × 10⁵ spores were let germinate for 6 h then exposed to 10 ml of enzyme solution for 3 h. The effect of other parameters that might enhance transformation yields including PEG concentration, DNA quantity and number of protoplasts was also examined. The most efficient condition for transformation involved the use of 10⁶ protoplasts, 20 µg DNA and 30% PEG (w/v). In the course of this study, a simple and appropriate modified protocol for transformation of F. graminearum was established. The method introduced is also more economical and faster than other current methods.

Background: Leptospirosis has been recognized as an important reemerging infectious disease caused by pathogenic Leptospira spp. A major challenge of this disease is the application of a basic research to improve diagnostic method. Outer membrane proteins of Leptospira are potential candidates that could be useful in diagnosis. Among them the lipL41 is an immunogenic protein which is present only in pathogenic serovars. In order to evaluate genetic conservation of the lipL41 gene, we cloned and sequenced this gene from Leptospira interrogans serovar Canicola.
Materials and Methods: Following the DNA extraction from the serovar, the lipL41 gene was amplified and cloned into pTZ57R/T vector and transformed into the competent E. coli (Top10). Recombinant clones were confirmed by colony PCR and DNA sequencing. The related sequences were then analyzed and compared with the sequences in the Genbank database.
Results: PCR amplification of the lipL41 gene resulted in a 1065 bp PCR product. The PCR based on the lipL41 gene detected all the pathogenic reference serovars of the tested Leptospira spp. It was revealed that in Iran the homology of the lipL41 gene between vaccinal and clinical serovars of Canicola was 100%. It also showed >95.9% homology with other pathogenic serovars in Genbank database, which indicates genetic conservation of this gene.
Conclusion: Because of the conservation of lipL41 gene among different strains of Leptospira and its exclusive presence in leptospira, it was revealed that the cloned gene could be further used as a good candidate for developing diagnostic methods such as ELISA and as positive control in diagnostic PCR.

Today, the population of cities along with their socio-economic issues has created a new form of city and urbanization. Tehran province has seen the most changes in the city and urbanization due to the establishment of the capital, the metropolis of Tehran. The question is what are the consequences of urban demographic changes in Tehran province? Therefore, this study tries to investigate the consequences of demographic changes in Tehran province on its urban network during the years 1355-1395. The research method is descriptive and analytical and its type is inferential. The data were extracted by library method and analyzed using regional planning models such as city rank-size and prime city index, entropy and prime city coefficient, Lorenz curve and Gini coefficient. The results show that the increase in urban population in Tehran province is due to the dispersal of the metropolis of Tehran and the concentration of urban population in the western part of the province is higher than other aspects of communication. Although medium-sized cities have partially repaired the spatial rupture in the province's urban network, according to the rank-size model, the distance between the metropolis of Tehran and other cities in the province is still very large and there is no balance in the province's urban network. Meanwhile, the urban population is not uniformly but in a cluster around the metropolis of Tehran and in the next order of medium-sized cities.
