Abstract
The present study was to evaluate the impact of feeding level and fish size on the growth factors,carcass composition and digestibility of rainbow trout. Six experimental treatments were assigned by the use of three feeding levels (maintenance, medium and satiation levels) and two fish sizes (43.02 ± 2.93 and 231.32± 6.74g) according to a 3×2 factorial design. There were three replicates for each treatment and the experiment lasted for 59 days. The results showed that there is a significant interaction effect between fish size and feeding level for body weight gain, final body weight and specific growth (p<0.05). Body composition (dry matter, energy, moisture, fat and protein) was affected by feeding level and size of the fish (p<0.05). However, the interaction effect between fish size and feeding level for body composition was not significant (p>0.05).The digestibility measurements showed that fish size and feeding level changed significantly digestibility of protein, lipid, energy and dry matter in rainbow trout (p<0.05). Maximum growth at satiation feeding level can reduce feed conversion ratio and increase waste production at both fish sizes.

Abstract
In this research, the possibility of asphaltene separation from the vacuum tower residue using the low cost industrial solvents such as 402, 404, 406, and 410 was investigated. In order to separate asphaltene the IP143/01 and ASTM D 3279-07 separation methods were utilized. In order to find the optimal state of asphaltene precipitation, Design of experiments software with three factors of residence time, the solvent-to-feed ratio and the volume percent of 406 solvent to the total solvent of 406 and 410 were used. The results showed that the effectiveness of each parameter in precipitating the asphaltene attributed to the ratio of solvent to feed, the ratio of solvent 406 to total solvent, and the residence time, respectively and there was a significant interaction between the basic parameters. The best asphaltene precipitation of 5.06% of 7.5% happens at the residence time of 36.97 hours, the ratio of solvent to feed of 35.95 ml/gr and the volume percent of 406 solvent to the total solvent of 27.20%. Asphaltene precipitation percentage for the optimal mixture of industrial solvents was 22.5% lower than the precipitated asphaltene from normal heptane solvent. However, according to the solvents price, industrial solvents (410 and 406) were approximately 50% cheaper than normal heptane, and hence on overall, there was a cost savings of more than 20%

Abstract
One of the most important Turkish tribe in Iran is Qashqai. This tribe has had its own culture, literature and language. It seems that in the process of modernization and Homogenization in Iran, this culture especially its literature is vanishing. Then, it is necessary to do some researches to protect it from being destroyed. Qashqai tribe has rich oral literature and culture whose stories are a part of it. Since up to now, no study with structural approach has been performed on these stories; we have examined ten stories as case study. The Methodology of the study is based on morphological model of Vladimir Propp, Russian formalist researcher. For this purpose, at first, all stories are analyzed and then each story’s model is mentioned with combination of their motions. This study shows that Qashqai tribe’s stories has the ability of structural study and to great extent is compatible with Iranian stories.

Abstract
Employees form an image of an organization's support and as results, attention to organizational goals and their realization. Their psychological empowerment allows organizations to be more flexible and responsive to changes. On the other hand, organizations need employees who are willing to step beyond the formal requirements of a job. Due to importance of these factors, this study examines the relationship between psychological empowerment on job performance, with organizational citizenship behavior as a mediator. Statistical population is employees of Alborz Insurance Branches in Tehran that are a total of 270. The simple random sampling used and according to Cochran formula a sample of 159 were selected. To collect required data, a standard questionnaire of Chiang and Hsieh (2012) was used. Confirmatory factor analysis and structural equation modeling based on Lisrel was used to assess the structural model. Results of testing hypotheses suggest that OCB mediate the relationship between psychological empowerment and job performance and perceived organizational support has effect on job performance, but this effect was not accepted on OCB. Also, psychological empowerment has effect on job performance and OCB, and OCB has effect on job performance.

Abstract
After the published of the symphony of the dead (1989), many of critics pointed to influence the Abbas Maroufi's novel of The Sound and the Fury William Faulkner. Twenty three years after the publication of this novel, today, some of critics repeat the influence to various forms. Perhaps with publish of the eternity to eternity (Analysis novel " symphony of the dead "), especially the essay "Is the symphony of the dead influence of Sound and the Fury? " by Elham Yekta and of the Sound and the Fury to symphony of the dead by Javad Eshaghian and other essays that describe comparative study of these two novels, does not need to study again. Furthermore, Nader Ebrahimi (1936-2008), in an interview as " Soak in the story" (1997), without any reference to the symphony of the dead, author of the novel imputed to "plagiarism", it's not about the Sound and the Fury, but Another time, i was loving the city (1966). In this paper, with attention to the principle of "angoisse de l'influence", as the conscience of writers, with emphasis on polyvalent, we answer to imputation the of Nader Ebrahimi about symphony of the dead and why and how the Abbas Maroufi influence of Another time, i was loving the city.

Abstract
The present research is aimed to evaluate the working memory (WM) in Persian words (as a L2) in comparison to it in Chinese words (as L1) in Chinese Persian learners. Thirty learners at Dehkhoda institute were chosen as the study sample. Sampling has been relied on the available subjects who took part in the visual n-back task which was specifically designed to measure WM. The participants had to press the congruent key (predetermined number 1) if the stimulus was the same as the one presented just before, and pressed incongruent key (number 2) if it was not. Then they took part in the stroop test. In psychology, the Stroop effect is a demonstration of interference in the reaction time of a task. the stroop test here included 40 stimuli- a pseudorandom selection of 20 Persian words and 20 Chinese words, selected among four main color which was written with incongruent ink. The participants had to press the key predetermined the color of the word- not ink-. Accordingly, the score of their WM “accuracy”, WM “mean respond time”, attention bias “accuracy” and attention bias “mean respond time” have been calculated separately for both languages and compared with paired samples T test. Results illustrate a meaningful difference between L1 and L2 among the selective attention mean respond time, WM accuracy and WM mean respond time, and didn’t illustrate meaningful diference between L1 and L2 among selective attention accuracy.

Abstract
Aims: The use of plants for treatment and food returns to ancient times. This study was conducted to examine the essential oil composition and antioxidant activity of the essential oil of
Artemisia sieberi Besser at 3 phenological stages and effect of grazing livestock on these properties.
Materials & Methods: For this purpose, 5 shrubs from two sites (under grazing site and enclosure site) were selected randomly at 3 phenological stages. In laboratory operations, essential oil of the species was extracted in by SDE method.
Findings: The results of GC/MS analysis indicated 45 compounds for grazed site with essential oil content 98.73%, and 42 compounds for enclosure site with essential oil content 98.54%. Also, α-tujune (21.63%), α-Pinene (19.53%), and Camphene (10.34%) were the main compounds in the enclosure site and α-tujune (23.70%), α-Pinene (20.33%), and Camphene (12.60%) were the main compounds in the grazed site. The results of screening antioxidant activity using two assays (DPPH and β-carotene-linoleic acid) showed that the free radical scavenging activity of essential oil (IC
50 µg ml
-1) in the first phenological stage (vegetative stage) was more than other phenological stages in two sites. Also, the inhibition of essential oil in the grazed sites had a significant difference with essential oil's inhibition in the enclosure site.
Conclusions: Effect of grazing on the composition and properties of the essential oil of this species can be considered in the planning of livestock grazing management. We wish our future research on this plant leads to the finding of new natural antioxidant compounds.

Abstract
The purpose of this research is to analyze Differential Adpositional Case Marking (DACM) in Vafsi within OT framework by using the generalization of Aissen’s (2003) Differential Object Marking (DOM) model. While Bossong (1985) has traced DOM in more than 300 languages, DACM has not been investigated typologically, yet. DACM, as a branch of Differential Case Marking (DCM), questions the effect of semantic and/or pragmatic features on case marking of object of adposition. Evidence from Vafsi (Stilo, 2004) suggest that animacy in object of adposition (OA), affects its case marking; i. e. human and animate OAs in Vafsi will be oblique case-marked, while inanimate OAs are direct (nominative) case-marked. DACM OT model is developed using Prince and Smolensky (1993), Smolensky (1995) and the generalization of Aissen’s (2003) DOM OT model. The constraints hierarchies are extracted using formal devices of harmonic alignment and local conjunction.

Abstract
Aims: One of the herbal indices that effects on the livestock grazing behavior is the herbal compounds including the essential oils, so the aim of the present study is the comparison of three Artemisia species in terms of the composition of essential oils coincident and the relationship between livestock grazing time from these three plant species.
Materials and Methods: Three Artemisia species (
Artemisia sieberi Bess.,
Artemisia kermanensis Podl
., and
Artemisia khorassanica podl.) in the natural from habitats with similar conditions were studied. Five plant stands were selected randomly from each species and the essential oils were obtained by SDE of air-dried samples and the essential oil were analyzed by GC-MS.
Findings: About 88% of essential oil compounds in these three Artemisia species were common and
Artemisia kermanensis Podl. had more essential oil percentage (98.47%) and
Artemisia sieberi had the lowest essential oil percentage (73.21%) while the rate of grazing on the
Artemisia sieberi Bess. was higher compared to two other species in the same vegetative stage. Also, 6% of the compounds were observed only in the
Artemisia kermanensis species, which is probably the presence of these compounds are the reason for the lack of feeding by the livestock of this species.
Conclusion: The selection of livestock for grazing of these three species to be highly relevant to their essential oil compounds, although the amount of these compounds has decreased in the third phenological stage, preventing livestock feeding on these species in the first and second stage of vegetation. Livestock grazing planning based on essential oil combinations can be a new horizontal in rangeland management. It seems the biochemical defense in the plants with essential oil is a way to combat animal grazing.

Abstract
One of the texts that has played an important role in the conception of Maroufi’s Symphony of the Dead (1989) is Ardabil dar Gozargah-e Tarikh[1] by Baba Safari (1920-2003). The two texts are so much interwoven that at times it becomes impossible to distinguish Safari’s voice from Maroufi’s. Although Marouf’s novel is not a historical one, it depicts the events occurring in Ardabil between 1934 and 1976. At first look, Ardabil seems to be whatconnects the two works. But beyond this, Maroufi not only reconstructs some of the historical events narrated in this book, but also creates some of his fictional characters borrowing from the descriptions of the historical figures that Safari has brought into life in his book. This article studies the influence of Safari’s historical work on Maroufi’s novel.

Abstract
Backgrounds: In recent years, Enterococcus species have emerged as a leading cause of nosocomial infections worldwide. The aim of this study was to determine the virulence biomarkers and antibiotic resistance profiles of Enterococcus spp. collected from a main tertiary teaching hospital in Bandar Abbas, Iran.
Materials & Methods: A total of 71 Enterococcus were isolated from clinical specimens of patients in different wards of a hospital. Enterococcus spp. were verified by detecting ddl gene using PCR-based method. Virulence-encoding genes including gelE and cylA were detected using PCR. Antibiotic resistance was assessed using the disk diffusion assay, and vancomycin resistance was identified using the E-test method.
Findings: Among Enterococcus isolates, 50 and 21 isolates were identified as E. faecalis and E. faecium, respectively. Most of the Enterococcus species were isolated from urine, followed by wound samples. The most prevalent virulence genes among E. faecalis isolates were cylA (60%) and gelE (30%); also, 19 and 14% of E. faecium isolates were positive for cylA and gelE genes, respectively. Many isolates of E. faecalis (84%) and E. faecium (76%) were resistant to one or more antibiotics and showed high resistance to gentamicin and ciprofloxacin.
Conclusion: This study revealed a high prevalence of ciprofloxacin and gentamicin resistance and a high frequency of virulence genes among E. faecalis isolates. Due to the high prevalence of MDR Enterococcus strains, control measures are necessary to prevent the emergence and transmission of these strains in different hospital wards.

Abstract
Backgrounds: This study aimed to assess the molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from community-acquired (CA) and hospital-acquired (HA) infections in Bandar Abbas, southern Iran.
Materials & Methods: This descriptive cross-sectional study was conducted on 110 S. aureus strains isolated from 59 outpatients and 51 inpatients during 2018-2019. Antimicrobial susceptibility testing was performed using disc diffusion method. Epsilometer test was used to measure vancomycin minimum inhibitory concentration (MIC). Cefoxitin disc (30 μg) was used to screen MRSA isolates. The presence of mecA gene was examined by PCR method. Staphylococcal cassette chromosome mec (SCCmec) types were detected in S. aureus isolates using multiplex-PCR. Chi-square and Fisher's exact tests were used to analyze the results.
Findings: Out of 110 isolates, 45 (40.9%) isolates carried the mecA gene: 20 (39.2%) isolates from inpatients and 25 (42.4%) isolates from outpatients. MRSA isolates showed the highest resistance to azithromycin (69.8%), tetracycline (60.4%), and clindamycin (32.1%), respectively. Vancomycin MIC against MRSA isolates ranged from 0.75 to 5 μg/mL. SCCmec type I, III, IV, and V were detected in 20 (44.4%), three (6.7%), 16 (35.5%), and six (13.3%) isolates, respectively.
Conclusion: The predominant SCCmec types were type I and type IV, which were detected in CA- and HA-MRSA isolates, respectively. No significant difference in the presence of SCCmec type III and antibiotic resistance was found between CA- and HA-MRSA isolates, indicating the possibility of cross-infection between these isolates. Developing appropriate treatment protocols to prevent the spread of MRSA infections in the community is currently an urgent need.
