This study investigated the construct validity and measurement invariance of the Teacher Emotion Questionnaire to introduce a valid and reliable instrument for assessing English-as-a-foreign-language (EFL) teachers’ emotions inside the classroom. Second language (L2) teacher emotions have been largely neglected, despite the fact that Educational Psychology has long recognized and researched the role of teacher emotions in different aspects of teaching and learning. To bridge this gap, the current study had 208 Iranian EFL teachers in private language institutes fill out the Teacher Emotion Questionnaire (TEQ), which assessed six emotions teachers experience in their classroom, i.e., Joy, Pride, Love, Anger, Fatigue/Exhaustion, and Hopelessness. The preliminary analysis of the data showed that six items from the TEQ had a factor loading below the minimum recommended level of 0.3, meaning that they contributed to the total variance in the participants’ score less than expected. The collected data were then submitted to confirmatory factor analysis (CFA) for the purpose of construct validation and establishment of the factorial structure of the TEQ. The CFA results indicated that the hypothesized six-factor analysis had more favorable goodness-of-fit indices than both a one-factor structure and a two-factor structure (e.g., positive versus negative emotions). Multilevel CFA revealed that the tested six-factor structure of the TEQ was invariant across male and female EFL teachers. The implications for the use of TES in EFL teaching contexts are discussed, and some suggestions are proposed for further validation of the TEQ in language teaching contexts.

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.

In this study, 30 mental states were suggested to 50 theatre actors. They designed a specific physical form for each mental state. In this process, 2000 images from actors’ gestures were collected. Images was surveyed by 321 accidental audiences; and among all images, images achieving the highest rate were selected. Reliability and validity of selected images were evaluated by a software designing for mind-reading's test though body. This study achieved its results mentioned below through preparation, design, implementation, analysis, record of results of a mind-reading’s test.
According to statistical results, the body has an ability to convey the mental state. We can figure out individuals’ mental states through body forms. Based on Baron-Cohen’s study, 30 body forms were determined. The relation between mind-reading through body and eyes was analyzed. Selected images for designing a mind-reading’s test through body were identified, and its reliability and validity were confirmed.
In this study, the first archive of images representing mental states through actors’ bodies has been designed and prepared. In comparison to men, women have a better function in understanding of mental states. Furthermore, bodies can represent mental states better than eyes.

Prepositions are linguistic elements that indicate the physical properties of referent and relatum and the geometry of the manner in which they interact with one another. Numerous studies have shown that prepositions in their abstract usages retain at least one of their spatial geometric features which is testimony to embodiment theory and it also suggests that understanding of abstract usages of prepositions can be better done by first studying the spatial usages of them. In this research we consider and analayse spatial geometry of different usages of Persain preposition /dᴂr/ applying Talmy's approach towards spatial structuring in language. Fourteen distinct usages were extracted from Hamshahri Corpus. The spatial geometry of each usage was analaysed and at least one image schema has been proposed for each usage. As a result of close study of various usages we observed that in all usages either the factor "enclosure" or "locus of control" or both are present in the geometry of  the preposition. In one instance we observed a tertiary reference object for locating the Figure in the scene. An investigation of one spatial geometry ascribed to the preposition /dᴂr/ led to suggesting a volumar schema for "way". Also in some usages the use of metonomy can be seen where part of the real Ground or an entity related to it appears as Ground in the sentence.

This study aimed to explore the impact of pragmatics instruction on the perception and production of expressive and directive speech acts by Iraqi EFL learners. The study also sought to investigate the attitudes of both learners and teachers towards the use of task-based pragmatics instruction in both conventional face-to-face and technology-based classrooms.  To achieve this goal, 120 Iraqi EFL learners took part in the study, divided into two experimental groups (conventional and technology-based classrooms) and one control group without pragmatics instruction. Data were analyzed quantitatively and qualitatively using statistical quantitative approaches for the former and content analysis for the latter. The results revealed that students who received instruction in speech acts, whether in conventional or online classrooms, performed better than those who did not receive any instruction in this area. Additionally, the findings supported the idea that online students outperformed their counterparts in conventional classrooms. Furthermore, the study found no significant gender differences in the speech act performance of Iraqi EFL learners. In the end, the benefits and challenges of task-based pragmatics instruction in online and conventional classrooms were discussed and implications were provided.

Histopathological and pathomorphological effects of 15 ppb mercuric chloride on Persian sturgeon, Acipenser persicus, were investigated using histological and electron microscopy observations. Light microscopy showed that the gill epithelial hypertrophy, wrinkling and hyperplasia in lamellar epithelia and lamellae fusion occurred after 48 h of exposure. Gill epithelia also showed occasional necrosis, which had almost been completed and blood emerged from the capillaries. However, occasional necrosis in some regions of the filament, both with blood emerging and with no bleeding, was observed by using electron microscopy. These injuries were well observed in inter-lamellar regions of the filament and also wrinkling of the lamellar epithelium. Ultrastructural observations showed some cellular disorders in gill epithelium of the Persian sturgeon, A. persicus, fry. In addition, increase in apical vesicles of the chloride cells and necrosis in apical surfaces of some chloride cells, hypertrophy and necrosis of the chloride cells’ mitochondrion and endoplasmic reticulum also were some of the other cellular disorders observed through transmission electron microscopy. In conclusion, the gills of A. persicus fry were sensitive to low concentrations of inorganic mercury (HgCl2).

Mithraism rituals can be considered the most ancient Iranian religion, that based on available information, the scape and sphere of influence not only large parts of Grate Iran, but also parts of India and Europe, especially in the first centuries AC, impressed, as on most of the information and documents that Western Scholars were presented, how the law plays an important role in shaping some of the traditions of Christianity in Europe. The aim of this research to understand the spatial structure Mithraeum architecture in Europe, as illustrated in the documents properly reflect the performance space is Mithraism of Europe. The main research question is that, how important Features of the original architecture and atmosphere of the Mithraeum architecture was in Europe? Descriptive and analytical research and data collection methods to the documents. The statistical properties of the first fifty of the Mithraea that during their investigation, which number about eight samples of documents is illustrated more about them, and took a closer look. This theoretical framework is based on the phenomenon and characteristics of cultural and religions factors in shaping how the ritual space is particularly important temples. The research results show that almost that many in Europe have been found from most of Mithraism architectural structures that were more or less similarity of cultural characteristics and world views of Mithraism. This structure consists of a rectangular space, which were divided into three parts that together form a line a space of three groups. The middle space, where more traffic and double the space in which two, people were used to deployment. In the end of temple, there was a place that most cases were above a floor and place the person or persons of higher authority, and performing some ritual ceremonies such as prayer and sacrifice the animals.

The Nahj al-Balagha (Arabic: نهج البلاغة‎ Nahj ul-Balāghah) (“Way of Eloquence") is the most famous collection of sermons, letters and narrations of Imam Ali. This book is Known for its eloquent content and considered a masterpiece of literature in Arabic language and literature. This valuable book many times has been translated into Persian by capable translators and scholars. One of the most famous Persian translations of Nahj al-Balagha was done by Sayyed Jafar Shahidi, distinguished scholar of the Persian language and literature and a renowned historian of Islam. Nahj al-Balagha employs many stylistic, linguistic and rhetorical features, and this use of linguistic and rhetorical features such as simile, metaphor, irony, challenges the translators of Nahj al-Balagha. Meanwhile Shahidi’s translation of Nahj al-Balagha has been a faithful translation in a way that he has tried to convey it faithfully on the one hand, and to find the exact Persian equivalents on the other hand. Using the descriptive and attributive method, this article analyzes the diction, figures of speech, and literary graces of the 114 elementary sermon of Shahidi’s translation. Shahidi has carefully translated figures of speech of Nahj al-Balagha into Persian, to some extent that, the eloquence of this translation draws everybody’s attention.  Shahidi has benefited from the Baligh simile and Makniyah Metaphor frequently. He has also used different types of figures of speech and rhetorical features such as rhyme, symmetry, contrast… which makes this translation more valuable and precious. And finally the authors have come to this conclusion that the rhyme is the most striking feature in this translation.

Nowadays, investigating and researching on energetic polymers in order to increase mechanical, thermodynamic, and detonational properties of them have been highly regarded. One of these energetic polymers is GAP. In this paper, molecular dynamics simulation has been used to compare the properties of GAP and GTP energetic polymers. GTP, in principle is the modified form of GAP, in which functional group of triazolium methyl nitrate has been added instead of azide. The mechanical properties of GAP is a challenging topic in the field of energetic materials. Due to the attributes of the 3 azoliom methyl nitrate ring, the mechanical and thermodynamic properties of GTP are expected to be higher than GAP. The results obtained by molecular dynamics simulation showed that GTP is a stable material and its mechanical properties such as Young, and shear modulus compared to GTP have been decreased 27% and 32% respectively, and bulk modulus, Poisson coefficient, and K/G ratio compared to GTPhave been increased 17%, 42%, and 71% respectively. It was also found that the detonation speed, detonation pressure, and oxygen balance of energetic polymer compared to GAP, have been increased 5%, 14%, and 21% respectively. As a result, usage of GTP will increase as a modified GAP material in applications such as clean and chlorine-free propellants for the solid propellant rockets and also safety systems of automobiles.

Dispersion type of layered clay plated in aqueous media creates different structures and affects the final properties of its suspension. On the other hand, the presence of different electrolytes in some industrial applications affects the stability of clay suspensions. Considering the application of clay nanoparticles in various industries and the importance of this subject, in this research, the effect of preparation method, nanoparticle concentration, type and ionic strength of electrolytic medium and time elapsed on the stability behavior of laponite nanoparticles suspensions were studied. The results showed that preparing of the suspensions indirectly, results in more stable samples. It was observed that with increasing of sodium chloride concentration, the repulsion between the clay plates decreased and the phase separation and instability of the suspensions increased at higher NaCl concentrations. Furthermore, it was seen that in all electrolyte media, gel-like structure develop with increasing of nanoparticle concentration. In presence of bi-valance CaCl2 salt, most of suspensions were unstable and have two phases and increasing of this salt concentration had not significant effect on their stability. In electrolyte media containing mono- and bi- valance salts (studied in this research), concentration of calcium cation determines the type of stability behavior of laponite nanoparticles suspensions.

 Resistance literature is the most important cultural strongholds for nations under domination. This word has always been associated with anti oppression and evokes it. This genre of literature has got a long bachground in the history that because of ruling oppression in muslim countries from alien countries and also imposed wars, has got a special representation. Iran and Palestine are two prominent examples of this country. Saleh Mahmood Alhowariis one of the poets who pays special attention to Palestine. Also TaherehSafarzadeh,with his poetry has defended his nation confronting aliens, and we see manifestation of resistance in her poems. Pride and national identity and patriotism, challenge, hope for a better future, and invitation to solidarity are of the common themes in the poetry of both poets.This study intends to express the themes of resistance literature in poetry of both poets and compare these kind of themes in their poetry using library tool and descriptive-analytical method the American School of comparative literature.

Beet western yellows virus (BWYV), a species of the genus Polerovirus in the family Luteoviridae, is an agriculturally important virus infecting over 150 plant species in 23 dicotyledonous families worldwide. A survey of BWYV in canola fields in Golestan and Tehran provinces of Iran using indirect triple antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA) indicated 8.3 % infection. The presence of BWYV was confirmed by amplification of the coat protein (CP) gene of the virus via running a reverse transcription-polymerase chain reaction (RT-PCR) on total RNA extracted from ELISA positive leaf tissues. DNA sequences of the BWYV coat protein (CP) gene of seven Iranian isolates were determined and compared at the nucleotide (nt) and amino acid (aa) levels with those of twelve BWYV isolates from different countries deposited in GenBank. Sequence analysis data showed that the identity of BWYV-CP at nt and aa levels among the Iranian isolates were 93.4 % to 100 % and 93.2 % to 100 %, respectively. The maximum similarity of isolates at nt and aa levels were 97.2 and 96.6 %, which occurred among two Iranian isolates (Ir 8 and Ir 100) and four isolates from France (L39967 and X13063) and England (L39973 and L39970). The recombination analysis among the nineteen isolates including seven Iranian isolates revealed that there was no distinct intra-specific recombination event among BWYV isolates. This is the first report of sequencing and analyzing of the BWYV CP gene of Iranian BWYV isolates.

Leptinotarsa decemlineata (Say) and Lasioderma serricorne F. are destructive pre-harvest and post-harvest pests of many plants in the family Solanaceae, and stored foodstuffs and non-food items, respectively. In this study, some biochemical characteristics of cellulase in the larval digestive tract of these pests were studied. Endo-β-1, 4-glucanase activity was measured against the substrate carboxyl methyl cellulose. Maximum activity of the enzyme in L. decemlineata and L. serricorne occurred at pH 7.0 and pH 6.0, respectively. The enzymes from L. decemlineata and L. serricorne were maximally stable at pH 7.0 and pH 5-6, respectively. However, the enzyme extracted from L. serricorne is more stable than that of L. decemlineata. Cellulase activity was in the highest level at 50 °C in both species. EDTA and SDS reduced cellulase activity, while the Ca²⁺, Mg²⁺ and Na⁺ ions had a significant increasing effect on cellulase activity. K⁺ did not have any significant effect on the enzyme activity. The values of Km and Vmax were 0.608 % and 0.0187 µmol min^-1 mg^-1 protein in L. decemlineata, and 0.99 %, and 0.0035 µmol min^-1 mg^-1 protein in L. serricorne, respectively. Zymogram studies revealed two bands of cellulase activity in the digestive tract of both species.

In order to understand the importance of particle size and agglomeration for nano-eco-toxicological studies in aquatic environments, the acute toxicity of two different types (suspended powder and colloidal) of silver nanoparticles (AgNPs) were studied in alevin and juvenilerainbow trout. Fish were exposed to each type of AgNPs at nominal concentrations of 0.032, 0.1, 0.32, 1, 3.2, 10, 32, and 100 mg/L. Lethal concentrations (LC) were calculated using a Probit analysis. Some physical and chemical characteristics of silver nanoparticles were determined. In the case of colloidal form, particles were well dispersed in the water column and retained their size; but in the case of suspended powder, particles were agglomerated to large clumps and precipitated on the bottom. In alevins, the calculated 96 h LC50 values were 0.25 and 28.25mg/L for colloidal and suspended powder AgNPs respectively. In the case of juveniles, the 96h LC50 of colloidal form was 2.16mg/L, but suspended powder did not caused mortality in fish even after 21 days. The results showed that both in alevin and juvenile stages, colloidal form is much toxic than suspended powder; this shows increase of nanoparticles size due to agglomeration, will reduce the toxicity. Silver nanoparticles are toxic materials and their release into the water environment should be avoided.

Asiatic citrus canker is a devastating disease resulting in drastic economic losses in citriculture worldwide. Amongst three different types of the disease, i.e. A, A* and A^w, the A* type is genetically less known. In order to comprehend the behavior of the Asiatic citrus canker A*-type strain (Xanthomonas citri subsp. citri) in the vicinity of the host cells, a targeted semi-quantitative transcript analysis approach via RT-PCR was carried out. A subset of sixteen genes, as representative of different steps involved in phytopathogencity, was analyzed on the culture medium (as uninduced) and compared with the subset isolated from the infected Mexican lime (Citrus auarntifolia L.) plants (as induced). The results showed that certain genes were up-regulated in induced condition, suggesting a putative role in bacteria-host interaction. Furthermore, the transcripts in induced condition could be classified into constitutive, early- and late-responsive genes, demonstrating their functional relevance during the host-pathogen interaction.

Background: Campylobacter spp. are the common pathogens that infect human beings via food. These bacteria are vibrio and have been implicated in abortion. Serotyping is the best way for typing with Penner scheme. C. jejuni and C. coli have 65 serotypes. C. coli is common in birds and dogs. Due to high rate of prevalence of Campylobacter in red-meat, chicken-meat and egg-shell, a suitable method to detect their prevalence, the most common species and serotyping group was necessary. This article describes the prevalence of Campylobacter infection, common serotyping group in 330 samples of red- meat, hen-meat and egg-shell. Materials and Methods: With three methods: enrichment, selective Preston and Skirrow and filtration with membrane filters Campylobacter swere incubated. Bacterial species were identified with physiological and biochemical tests. Penner serotyping was defined with reference antiserum Ag-O and direct agglutination. Results: Prevalence of Campylobacter infection was 21(23%) in red meat, 33(27.5%) in hen meat and 38(31.6%) in eggshell. In egg-shell samples: C. jejuni 20, C. coli 14, C. lari 3 and C. concisus 1 case. In meat common Penner serotyping for C. jejuni O₂ had the highest rate. In hen, common Penner serotyping: for C. jejuni O₃ and in egg-shell for O₁, O₂ and O₃ had the highest rate. Conclusion: Most infection of campylobacter was found in egg-shell; most common species in these three samples were C. jejuni, then C. coli and C. lari. No C. consicus was found in meat but it was found in hen and egg-shells. In common Penner serotyping for C. jejuni O₂ and O₃ were the most common and for C. coli in meat O₄₉ and in hen and eggshell O₅ were the highest.

Background:  Aeromonas spp. can cause diarrhea and various infections in humans. Access to rapid techniques with a high sensitivity and specificity is strongly needed for the identification of Aeromonas species. The aim of this study was to evaluate two different methods including API 20E bacterial identification tests and the molecular detection using PCR primers specific for 16s-rRNA and 23S-rRNA genes sequences for identification of Aeromonas spp. in stool samples from patients with diarrhea. Materials and Methods: One hundred stool samples from diarrheal patients were collected. All isolates were subjected toAPI 20 E strip tests and PCR using specific primers for identification of Aeromonas spp. Results: The API 20E analysis identified 2 (2.2%) isolates as Aeromonas spp. Molecular identification by aero-23S-rRNA gene confirmed the same 2 isolates as identified by the API 20E strips. Conclusion: Both API 20E system and PCR method using Aero 23S-rRNA primer were found to be accurate in identification of Aeromonas spp. isolates with highconfidence.

This paper is an attempt to analyze the ergative constructions in Hawrami. Like other Kurdish dialects, Hawrami utilizes split ergativity only in the aorist constructions. Along with the process of Clitic Doubling, this dialect uses another mechanism for manifesting the ergative pattern. This rare mechanism is only found in Hawrami and not elsewhere in Kurdish. In the constructions, which are derived according to the second mechanism, the direct object and the subject undergo the processes of toplicalization and focusing, respectively. Hence, comparing to the other ergative constructions, which are derived on the basis of Clitic Doubling; these specific constructions bear a more marked semantic interpretation. The constituents of these marked ergative constructions follow a rigid order: the direct object appears at the beginning, the subject, which is always accompanied by Oblique case marker, gets the second position, and the final position is occupied by the past transitive verb. Making any slight change in this order would result in the ungrammaticality of the construction. The present paper, on the one hand, tries to describe the main characteristics of both marked and unmarked ergative constructions in Hawrami, and seeks to provide a theoretical account for the derivation of marked ergative constructions and their characteristics on the other. The proposed account is mainly based on the theoretical apparatus of Minimalist Program; especially the recently introduced notions of Split CP Hypothesis, Focus Phrase, and Topic Phrase.
