Autism is a neurocognitive disorder. Many children with autism do not have a change in language and usually tend to have literal interpretations of phrases, which makes it difficult to understand metaphorical language, which can be seen in both visual and visual metaphors. The aim of this study was to compare auditory and visual metaphorical perception in children with mild autism and normal children. The present study is a cross-sectional and causal-comparative study. The statistical sample of this study includes 30 boys aged 7 to 10 years with mild autism studying in educational centers for exceptional children in Mashhad and 30 normal children matched in terms of age who were selected by convenience sampling method. After initial language assessment, they were assessed by metaphorical perception test and U Mann-Whitney test and SPSS 23 software were used to analyze the data. The results of data analysis showed that in metaphorical perception in general there is a significant difference between autistic and normal children (P <0.001), also, in understanding visual and auditory metaphors, the two groups showed a significant difference (P <0/001). The obtained results indicate that compared to normal children, children with autism have a lower performance in terms of understanding visual and auditory metaphors, and considering this issue can be used in planning and designing educational content and rehabilitation interventions in order to improve educational performance and social benefit of these children.

Derivational suffix “-ak” is one of the Persian productive affixes attached to different bases and creates many different meanings. Historical evidence affirms despite of the diversity of meaning, all the derivations come from the same original affix, with high potentiality in polysemy. The present article follows the cognitive-typological approach aims at investigating the polysemous behavior of the mentioned suffix while introducing the (sub)schemas of derivations in the framework of Construction Morphology. It deals also with the processes of metaphor and metonymy as two bases involved in the semantic extension. And then, by concerning the achievements of the first part with typological considerations, it shows the relationship between the cognitive processes involved in the polysemy and the typological motivations that follow them, i.e., economy and iconicity. Moreover, it examines how the typological explanations, specifically the concept of the semantic map, are not only valid for cognitivists, but also it can address more specific issues such as explaining the existence of polysemy within a single derivation. In this study, the Semantic Map Connectivity Hypothesis is also confirmed by those derivations that simultaneously imply more than one meaning, or that have undergone a change in meaning over time.

In general, temporary well plugging is essential for repairing of oil and gas wells due to their long life time. One of the newest methods used for this purpose is gel polymer plugging. The strength of the gel in the well conditions is one of the most important challenges in the application of gel polymer in the temporary well plugging in work over operation. In this study, silica nanoparticles were used to improve the strength of polymer hydrogels. The bottle and rheological tests were used to determine the gel strength in desired well conditions (high temperature and high salinity). Also, the gel strength properties and swelling behavior were studied in various conditions such as distilled water, formation water, tap water and oil. It was observed that the strength of the gel increased from 520Pa to about 36kPa (5000% increase) by adding nanoparticles. Also, the gel swelling in the aqueous solution has been significantly reduced. Based on the results obtained in this study, a polymer gel containing 9 wt.% of silica nanoparticles with structural strength and thermal stability at 90 °C was introduced for field studies.

In this study, the effects of drying temperature and mechanical pressure on the surface structure and dynamical properties of polyaniline (PAni) were studied. PAni was synthesized through the aniline polymerization process in the presence of ammonium persulfate in acidic medium and normal methyl-2-pyrrolidine solution. The obtained solution was dipped on a substrate of quartz glass. Atomic force microscopy (AFM) analysis based on nano-indentation tests were used to determine the values of hardness, Young’s modulus and Poisson’s ratio of the films. The results of the analysis of the scanning electron microscope demonstrated that the surface morphology of the film is changed from a fiber-to-interconnected cross-linked networkby increasing the drying temperature. The transmission electron microscope analysis showed that the diameter of the fibers on the surfaces dried at 318 K and 418 K was 18 and 30 nm, respectively. AFM results showed that the mean surface roughness of PAni film at 318 K without mechanical pressure was 63 nm, while for the film pressed at 5 MPa was less than 35 nm. Thermo-mechanical analysis showed that the glass transition temperature of the PAni film prepared without mechanical pressure and the film pressed at 5 MPa were 386 K and 378 K, respectively. Investigating the temperature dependence and applied pressure on the film surface in determining the viscoelastic properties of the PAni nanostructured film can provide readers with appropriate information about the storage and loss modulus of the film and the activation energy of the polymer layer during the thermal decomposition process.

Semantic Space of šod-{n ‘to become’ in Persian: A Cognitive Account This paper attempts to explore the semantic space of šod-{n ‘to become’ in Persian in order to address some basic features of linguistic cognition (e.g. analyzability and compositionality). One of the highly-frequent verbs in Persian is šod-{n, which with regard to its different functions at the level of sentence, can be considered as the most active verb in this language. According to a diachronic viewpoint, the same verbal form, šod{n, with four distinctive functions (as a main verb, as a copula, as a modal verb, and as the verbal constituent of complex predicates) plays an important role in Persian verbal system. The passive construction in Persian is considered as a Complex Predicate in which šod-{n combines with different linguistic categories such as noun, adjective, prepositional phrase and past participle (X in general). Its semantic space indicates that various types of constructions including šod-{n form a network of meanings, in which the verbal element šod-{n is meaningful, in contrast to the previous studies it's passive construction which considered it as a purely syntactic element carrying no meaning. Therefore, the passive construction in Persian is viewed as analyzable in which šod-{n is not a random occurrence but rather an extension of its other uses. The relatedness of the uses of šod-{n provides further evidence for the claim in Cognitive Grammar that the passive construction is part of a larger network of related syntactic constructions and not derives from the active construction.

The boundaries are completely complex spatial-geographical phenomena that include several dimensions and parameters. This spatial-geographic phenomena has become the focus of governments due to their importance and position in order to establish order and security within the country and to protect national interests and different efforts are done to protect them. To achieve this, the first and basic step is to know the dimensions and parameters that form and affect the borders. This research tries to determine these dimensions and parameters and their impact on urban development of Javanrood city. Accordingly, a questionnaire consisting of parameters and components affecting the development of border areas based on nine dimensions (territorial, socio-cultural, economic, political-governance, geopolitical, defense-security, historical, legal-structural and technological) is projected. The present study is descriptive- analytic in terms of it's practical purpose and in terms of the method of data collection. Since the aim of this study is to investigate the effects of security parameters on the development of border cities, the research is a descriptive correlational study. The results showed that among the components of the territorial dimension, environmental resilience; among the components of the socio-cultural dimension, the existence or absence of social capital in the border city; among the components of the economic dimension, the dependence of border residents on economic interaction with border; among the components of political dimension, level of freedom of action of local governments on both sides of border; among geopolitical components, geoeconomic position of border; among the defense-security components, intervention of local players; among the historical components, human and physical commonality between the two sides of the border; among the components of the legal and structural dimension, the government's attitude towards the people and the border; and among the components of technology, border infrastructure and technologies are as the most important and influential factors influencing the border development of Javanrood city.

Some studies of complex predicates suggest that light verbs are bleached semantically and are unable to bear the role of an autonomous predicate (Jespersen, 1965; Cattell, 1984; Grimshaw & Mester, 1988). Although it is accepted that the semantic content of light verbs is deficient, we address the issue that such a claim ignores the semantic relation between light verbs and the corresponding main verbs. The claim in this paper is that light verbs preserve the force-dynamic schemata of the corresponding main verbs totally systematically but the concept area is transferred from physical to abstract-psychological domain. Indeed, it is claimed that, although light verbs do not have totally predictable meaning, their contribution to the meaning of the predicate is completely systematic and to some extent clear. The present study focuses on two light verbs “ KARDAN” ( to do) and “ DASHTAN” ( to have) to indicate somewhat this systematization.

During the past decade, natural plant products as environmentally safe option have received attention for controlling phytopathogenic diseases. Investigation of plants containing natural antimicrobial metabolites for plant protection has been recognized as a desirable method of disease control. The fungus Fusarium oxysporum causes diseases such as root rot, damping off and Fusarium wilt and it infects many plant species and crops. Methanolic crude extracts of 30 plant species belonging to 17 families collected from the west of Iran were screened for antifungal activity against F. oxysporum during 2012. Bioassay of the extracts was conducted by agar dilution method with five replications. The inhibitory effect of the extracts was examined at concentration of 2000 ppm. Twenty out of 30 tested plant species (67%) showed inhibitory activity against mycelial growth of F. oxysporum. The most effective extracts with more than 50% inhibition belonged to Haplophyllum perforatum and Calendula officinalis. High number of plants with antifungal activity in this experiment showed that the flora in the west of Iran could be regarded as a rich source of plants with antifungal activity. Therefore, further screening of other plant species, identifying active fractions or metabolites and in vivo application of active extracts are in progress.

The effects of dominant shrub species on soil organic matter (SOM), including total soil carbon (SC), total nitrogen (N) and particulate organic matter (POM) were studied in three stands differing in the type of shrub species, i.e. Astragalus microcephalus (shrub), Pteropyrum aucheri (shrub) and Prangus uloptera (non-shrub).The stands were located in arid grasslands of north-western Iran. For this purpose, 18 soil samples from each stand were systematic-randomly collected (by auger) from each depth of 0-15cm and15-30cm, along 6 transect in each stand.The results showed that the stands with the highest abundance of P. aucheriand A. microcephalushad the highest values for SC (0.99% and 0.98%) in both depths, and the highest values for N (0.13% and 0.12%), respectively. The highest POM percentage for carbon (0.24%) and nitrogen (0.03%) were observed in the stands with the highest abundance of A. microcephalus. The proportion of micro-aggregates (28.48%) was significantly higher than macro-aggregates (20.46%) in the upper soil layer of the stand with the highest abundance of A. microcephalus as compared to the others, while no significant difference detected in micro- and macro-aggregate contents of the lower soil layer between the stands. Therefore, the type of shrub species in the grassland communities had important effect on soil organic matter.

Abstract:
Research subject: In water injection process, part of the surface active agents that are naturally present in oil can be dissolved in injected water. The presence of these substances affects the surface phenomena of the three phase water-oil-rock system. The effect of these substances on modification of the ionic composition of injected water has been less investigated in previous studies.
Research approach: In this paper, first, the effects of acidic compounds in crude oil and connate water composition on initial wettability of carbonate rock were investigated. Then to investigate the wettability changes of oil-wet calcite rock, single-salt aqueous solutions of MgCl₂, CaCl₂, KCl, and Na₂SO₄ having concentrations of 0.1 to 1 molar were used.
Oil–water interfacial tension (IFT) for distilled water and salt waters in various concentrations were measured and compared. Variations of calcite rock surface properties were investigated by contact angle measurement after aging of thin sections in oil and salt waters.
Main results: Results indicated that by increasing ion concentration and ionic strength of salt waters, IFT decreases due to dissolution of acidic compounds of oil at the interface of oil and water. Moreover, for high content of acidic compounds in the oil, Magnesium ion has the most impact on reducing IFT and altering the rock wettability. So that by increasing the concentration up to 1 molar, IFT and contact angle decrease to 1 mN/m and 42 degrees, respectively.
Contact angle measurements revealed that the composition of connate water is effective in changing the initial wettability of the rock, and formation of ionic-organic layer adjacent to the rock surface is one of the most important factors in wettability alteration. The presence of Magnesium ion in connate water decreases the contact angle to 145 degrees and causes the rock surface to become more water wet.
Also, increasing solubility of oil-soluble acidic compounds in the aqueous phase has a significant effect on the rock wettability. The experimental results showed that the interaction between ions in the aqueous phase, especially the divalent ions, and surface active agents (carboxylic acid) determine the surface behavior of water in contact with oil and rock.
 
Keywords: Wettability, IFT, Acidic oil, Divalent ions, Ionic-organic layer

The issue of management and planning for urban fringe in different countries always experience different approaches, attitudes that are generally in the form of protection or development of urban fringe and surroundings areas, because it depends on political, economic and institutional developments over time. For this reason, there is no uniform and formal definition of urban fringe among different countries. Over the past five decades, city of Tehran has adopted different policies in the plans and provided projects which were different in the preparation and implementation. In the present study, five decades of planning for the Urban Fringe of Tehran are investigated and analyzed, and these programs have been studied and analyzed from two dimensions of policy and quality. The paper is applied and is based on a non-intrusive interpretive approach. The information gathering tools are library studies and use of various sources and texts. The study's findings for policy analysis identified five categories (management, planning, organization, conservation, development) and for analyzing the quality of the seven categories (program presentation, effect of reality, popular participation, infrastructure capacity, land status, implementation and adaptability). The results of the analysis of the programs show that in the developed programs the main approach and policy is based on the protection of Urban Fringe, which in order to achieve it should improve the integrity (due to the way of implementation) and legitimacy (due to lack of public participation) of the programs.

Research subject: Nanomaterials are substances that, because of their size, can easily penetrate small pores and apply their impact. Nanofluids can allow appropriate wettability change in the reservoir rock, therefore, an accurate understanding of the behavioral mechanisms of these nanofluids is important in changing the wettability. This is because if there is no proper understanding of these mechanisms, they may exhibit the opposite behavior and cause damage to the reservoir. In previous research, CuO / TiO2 / PAM nanocomposite was synthesized and mechanistically introduced.
Research approach: In this study, in continuation of the previous study, the behavioral and mechanism study has been investigated in a more accurate and documented manner, and spectral absorption tests, chemical flooding, and relative permeability diagrams confirm the effectiveness of enhanced oil recovery results of this nanocomposite. In carbonate rocks due to the positive surface charge of the rock and the negative charge of the nanocomposite, adsorption of nanomaterials in a double electrode layer state has been suggested as the dominant mechanism of wettability change. In sandstone rocks due to the charge coincidence of rock surface and nanomaterials which are both negative, the mechanism of disjoining pressure was the dominant mechanism of wettability change. To prove the abovementioned behaviors 200 ppm concentration of nanofluid was analyzed by spectroscopy method of adsorption analysis to validate the attraction forces of the nanocomposite with carbonate rocks and repulsion forces with sandstones.
Main results: Dynamic chemical flood tests were performed to confirm the effectiveness of this material in increasing oil production and showed 8.5% and 6.35% increase in oil production for carbonate and sandstone lithologies, respectively. Relative permeability diagrams showed an intersection point in the carbonate system with a 10% increase in water saturation and an intersection point in the sandstone system with a 12% increase in water saturation and the behavioral effect of the material at the studied concentrations.

In this study, the efficiency of essential oils from asafoetida, Ferula assa foetida L.,geranium, Pelargonium hortorum L.H. Bailey and walnut leaves, Juglans regia F. was investigated on nutritional indices of Rhyzopertha dominica (F.) adults. Wheat grains were treated with different concentrations of the oils. The nutritional indices: relative growth rate (RGR), relative consumption rate (RCR), efficiency of conversion of ingested food (ECI) and feeding deterrence index (FDI) were measured at 28 ± 2 °C, 65 ± 5% R. H. in continuous darkness. RGR, RCR and ECI deceased as the concentration level was increased. While, FDI percent increased significantly as the concentration level increased. Asafoetida oil had the most efficiency on nutritional indices and 28.61 ppm of the oil was enough to decrease RGR, RCR and ECI% to 0.032 mg/mg/day, 0.444 mg/mg/day and 6.994%, respectively. FDI percent of adults exposed to 6.5 ppm of asafoetida oil was 13.31% which increased upto 64.62% at the concentration of 28.61 ppm. In the second experiment, the effect of tested essential oils was evaluated on F1 progeny reduction of R. dominica. Walnut and asafoetida leaves essential oils significantly suppressed progeny production by (59.92%) and (53.2%) respectively.

In this study, anti Alternaria solani effects of essential oils of 11 medicinal and aromatic plant species belonging to four families collected from the west of Iran were investigated based on agar dilution method with five replications at concentration of 1.0 µl/ml. The results showed that the highest inhibitory effect belonged to Oliveria decumbens, Cinnamomum zeylanicum, Carum copticum and Thymus kotschyanus which completely inhibited the mycelial growth of the fungus. Therefore, their activity was examined in lower concentrations, too. The essential oil of O. decumbens at concentration of 0.50 and 0.25 µl/ml completely suppressed the mycelial growth of the fungus. The major constituents of its essential oil were carvacrol (46.53%), thymol (23.75%), p-Cymene (13.70%), γ-terpinene (7.66%) and myristicin (3.65%), respectively. Thus, the essential oil of this species with the highest anti-Alternaria activity could be selected for further studies on in vivo application as natural fungicide.

The yield and quality of oil extracted from common kilka (Clupeonella cultriventris caspia) through a novel extraction technique with supercritical fluid CO₂ and also ethanol co-solvent extraction at 30 MPa pressure and 58°C temperature of for 90 min were compared. Addition of ethanol co-solvent significantly increased the total oil yield (p˂0.05). Moreover, the qualitative characteristics of the extracted oil with ethanol modified the solvent acidity, peroxide and TBA index considerably less than the oil extracted by supercritical fluid CO₂. Fatty acid composition of the oil extracted with the two extraction methods showed there was no significant difference in SFA and PUFA fatty acids (p˃ 0.05). In general, the two methods used in this work didn’t considerably affect the fatty acid composition of the extracted oil.

This paper attempts to investigate the Persian morphological system in the framework of Lexical Morphology Model (Kiparsky, 1982). The main goal of this research is to study the efficacy of the model in analyzing the Persian data. Having introduced the Lexical Morphology, some data which are counterexamples to the model at first sight, will be discussed. It will be shown that on the basis of different syntactic, semantic and cognitive criteria there is some kind of conformity between the data and the Lexical Morphology Model; although it is asserted that the efficacy of the model to analyze the English data (the language on which the model is designed) is more than its efficacy in Persian. In addition, the author suggests that in order to cope with some inadequacy that Kiparsky’s model encounters to analyze idioms (listed syntactic objects) the model should be revised by a loop connecting the syntax level to lexicon. Therefore, idioms are firstly formed in syntax, after lexicalization they will return to syntax. It seems that this loop makes the model much more efficient.

The present paper is a typological analysis of restrictive and non-restrictive relative clauses in Farsi and German. This study makes an attempt to determine the elements used in Farsi and German to differentiate restrictive relative clauses from non-restrictive ones. A second question that this study aims to answer is which noun phrases can serve as the head of relative clauses. The results show that Farsi as well as English, Bemba and Hebrew use formal elements to differentiate between the two types of relative clauses. In German, however, semantic and pragmatic elements are used for the same purpose. The results further show that in both languages, there are restrictions in the choice of referents for relative clauses. An example of such restriction is that in German, unlike in Farsi, a proper noun cannot serve as the head of a restrictive relative clause.
