Considering EFL teachers’ identities and emotions as discursive practices through a post-structuralist lens offered by the concept of navigation of emotions, this study sought to explore EFL teachers’ emotional experience in online classes during online education to examine the way their emotional navigation helped them negotiate their identities. The participants, including 17 Iranian EFL teachers, working at universities in the West, North, and East of Iran, were chosen using purposeful sampling. To generate data, in-depth interviews and personal documents were used, which were analyzed using inductive thematic analysis. The participants spoke of the experience of mixed emotions, creating the sense of ambivalence, which offered the possibility of dialectic thinking for reconciling contradictory views and questioning the existing dominant and preconceived ideas. Moreover, they navigated their emotions through emotional reflexivity and positive reframing. While emotional reflexivity, as a process of self-confrontation, consisted of relational struggles and agency, reframing, as an example of deep acting, entailed emotional resonance or a sense of aliveness and connectivity as well as a possibility for stressing the transpersonal attachment, as a novel concept to be addressed in teaching English. The role of positive emotions in enriching language learning processes, which is mainly ignored in language education, was underscored because the cultivation of positive emotions in English language learners increases their intrinsic motivation, enhances their engagement, and creates a sense of belonging to the target language.

To compare the seed characteristics in accessions of Atriplex canescens under exclosure and non-exclosure conditions, two even-aged sites were selected with an area of 400 ha as the exclosure and 1000 ha as non-exclosure area. To conduct the study, 30 species were randomly selected in autumn 2009 in reference area of the sites and seeds were collected. Some important seed characteristics were studied in the laboratory. Data analysis was conducted using SPSS 17 software and mean comparisons were performed by Duncan's Multiple Range Tests. Results showed that the winged seeds did not germinate under all studied treatments in both sites. Moreover, maximum seed germination was recorded for the seeds soaked in cold water for 24 hours and placed in the shade for 48 hours. According to the results of the independent t-test, no significant differences were observed for germination percentage, germination rate, and vigor index in both sites at both 1 and 5% probability levels. In other words, the seeds collected from the exclosure and non-exclosure areas were similar in terms of the mentioned characteristics. However, seed yield, 1000-seed weight and seed moisture content showed significant differences at 1% probability level with higher amount in exclosure area.

The control of bacterial diseases of fish has always been one of the most important problems of aquaculteriets in recent years. One of these problems is bacterial resistance. Using antibiotics can cause problems for consumers. Therefore, the use of new antimicrobial agents with minimal complications is common. In the present study, using the acid-thermal method, the bentonite structure was modified and the chitosan and bentonite hybrids were modified in the stage of development. The structure of the compounds was studied using the Infrared Fourier Transform Spectrometry (FTIR), Surface Electron Scanning Microscopy (FE-SEM) and X-ray diffraction spectroscopy (EDX). Antimicrobial activity of two types of modified bentonite on gram negative bacterium Aeromonas hydrophila was studied in vitro using two methods of disk diffusion and microdilution. The results of the disc diffusion method showed that the antimicrobial compounds produced had antibacterial properties in experimental conditions against the Aeromonas hydrophilia bacteria. Antimicrobial activity (MIC and MBC) was determined using microdilution and clonal counting in Agar culture medium. The results showed that the modified compound with the acidic method had MBC of 28.57 and 14.28 mg / L for Aeromonas hydrophila bacteria in 10 minutes and 30 minutes. For chitosan and modified bentonite composite, MBC was 14.28 mg / ml for Aeromonas hydrophila bacteria in 10 and 30 minutes. The results of this study showed that modified bentonite and composite compounds have strong antimicrobial effects and can remove pathogens in laboratory conditions and can be used as new compounds to control pathogens in breeding systems.

This article explains the common themes of Shahriar and Fowzi Maalouf's poems by asking what common themes of their poems about nature were. To answer this question, in the research process, a descriptive analytical method has been used based on library studies and content analysis of the data. The findings of this research indicate that Shahriyar has given some reflection on the nature of the Fowzi due to a periodic crossing of his life in relation to romantic tendencies in nature. Shahriyar's attitude toward nature is the result of his own experiences and personal acquisitions, while in Fowzi's view, nature is the source of inspiration for many concepts. The characterization of nature is more realistic in the sense that the Fowzi's poetry takes on the utopianism.

In this study two Bacillus pumilus including ToIrFT- KC806241 and ToIrMA-KC806242 were obtained from tomato fields and characterized based on phenotypic and molecular properties. Their possibility to reduce root knot disease of tomato caused by Meloidogyne javanica was evaluated. The experiments were done in lab and under pot conditions. Application of the ToIr-MA against M. javanica reduced the number of galls and eggs. Preliminary results indicated that the ToIr-MA has an ability to produce proteolytic enzymes in lab conditions. It seems that the bacterial culture filtrates can suppress egg hatching and increase juvenile's mortality, but the role of these metabolites in disease suppression needs to be investigated. Significant enhancement in root and shoot length (33%) and dry root and shoot weight (64 and 67%) was also recorded over usage of strain ToIr-MA in comparison to untreated controls. Additionally, survival of bacterial strains in rhizosphere and increases in population density were seen using root colonization assay. To our knowledge, this is the first time that such B. pumilus strain with nematicidal activity against M. javanica has been reported in Iran which may suggest to manage disease and change microbial population dynamics in the rhizosphere.

Aim: Identification of contributory factors in smoking and gaining insight into the roles played by each of these factors including health literacy (HL) may account for quitting or decreasing the prevalence of smoking. The aim of the current study was to identify the effects caused by different HL levels on smoking.
Methods: 347 students inhabiting the dormitories of Shahid Beheshti University of Medical Sciences were included in a cross-sectional correlational study. Random cluster sampling was used for the selection of participants. HELIA questionnaire (used for HL measurement in Iranian urban population between 18-65 years of age) and a researcher-made questionnaire (for determining the status of smoking in individuals) were used to collect information from the participants. All data were statistically analyzed by SPSS software.
Findings: The mean and standard deviation of HL score was 70.52±14.12 out of 100. The results indicated that among the university students, 59.7% (201 people) were non-smokers, 23.1% (78 people) were smokers, and 17.2% (58 people) had experienced smoking. These findings reveal that HL is significantly correlated with smoking in university students. Also different levels (insufficient, relatively sufficient, and sufficient) of HL show its significant correlation with smoking, meaning that less HL levels are accompanied by a higher chance of smoking.
Conclusion: The relatively high prevalence of smoking in university students and the impact of HL on smoking highlight the need to increase the level of HL in university students and develop an efficient tool for measuring smoking literacy in all age groups.

Two different microhabitats (cropped fields versus established date-palm farms) in two different cities in Khuzestan Province, Southwestern Iran, were sampled monthly during 2011-2012 in order to assess the role of anthropic uses of soil on the biodiversity of oribatid mites. A total of 17 species of oribatid mites belonging to 10 families and 15 genera were identified (nine species were collected from the fields and 17 species were collected from date-palm farms). Among the collected species, Scheloribates fimbriatus with 22% relative abundance and Acrotritia ardua with 19% were dominant species. The Shannon index of species diversity and equitability was used to analyze data. Species diversity of oribatid mites and equitability were significantly greater in the date-palm farms than in the cropped fields. Time of year had no significant effect on biodiversity.

The error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. Global positioning system is the best aiding system in this case. In this paper we first simulate a GPS and INS; Then simulate tightly integration and finally review adaptation method of Kalman Filtering a Fuzzy adaptive Kalman filter is proposed in which adaptation is accomplished by adaptive tuning of covariance matrix of measurement noise (R) and process noise (Q). We have achieved adaptive tuning using Fuzzy systems and Covariance - Matching techniques .The results show that the adaptive fuzzy integration of GPS and INS would lead to better performance comparing to the usual methods of integration in which both R and Q matrices are constant.

Aims: Influenza A virus subtype H1N1, known as H1N1 influenza virus, could cause moderate to severe swine influenza in humans. H1N1 influenza is associated with high mortality rate. Effective symptom management could significantly reduce the mortality rate. This study aimed to determine the clinical manifestations, outcomes, and predictors of mortality in patients with H1N1 influenza, admitted to hospitals during January to September 2016.
Materials & Methods: This retrospective descriptive-analytical study was conducted during January to September 2016 in eight hospitals located in Razavi Khorasan province, northeastern Iran. The medical records of 65 patients were retrieved, and the necessary data were extracted from the records using a demographic questionnaire and a clinical manifestations checklist. The SPSS software Version 23.0 was used to analyze the data via the measures of descriptive statistics and the logistic regression analysis with odds ratio.
findings: The most common clinical manifestations of H1N1 influenza were headache (70.8%), numbness in the extremities (63.1%), myalgia (60%), cough (58.5%), fever and shivering (53.8%), and nausea (53.8%). In total, 14 (21.53%) patients had died due to H1N1 influenza. The significant predictors of death were dyspnea (OR: 13.91, p: .032), myalgia (OR: 0.04. p: .010), and age (OR: 1.05, p: .024) so that dyspnea and myalgia were associated with 13.9 and 0.04 times higher odds of death, respectively. Moreover, each one year increase in age was associated with 5% increase in the odds of experiencing death.
Conclusions: In the case of H1N1 influenza epidemics, care services need to be allocated more to patients who have higher age and suffer from myalgia and dyspnea.

Research subject: Bio-hydrogen is a renewable energy source with many economic and environmental benefits as a fuel. Controlling the concentration of the substrate in the reactor has a significant effect on the amount of hydrogen production. However, bio-hydrogen production is a nonlinear process that requires the implementation of nonlinear control methods. In this paper, substrate concentration in an anaerobic bio-reactor is controlled using the feedback linearization method.
Research approach: The model employed for the simulation is a well-known model consisting of three state variables. The proposed controller is a globally linearized controller (GLC) designed based on the feedback linearization technique. In this method, the nonlinear system is precisely linearized by a transformation of the coordinate system. As a result, the linearized system can be controlled using a linear controller. In order to linearize the system, a nonlinear compensator is designed using the design model and applying the concepts of differential geometry. Proportional-integral (PI) controller is adopted as a linear controller. GLC controller performance has been compared with a nonlinear controller (NC) and a PI controller. The performance of these controllers has been studied by numerical simulation based on the integral of time-square error (ITSE).
Main results: The simulation results show that substrate concentration control can contribute to the hydrogen production. The control method applied has better set-point tracking than the other two control approaches. The ITSE performance index for the feedback linearization method is lower than the other two methods. The nonlinear feedback controller fails if the kinetic parameters are changed by 25%, but the PI method and the feedback linearization are robust against model uncertainty. An efficient controller guarantees stable bio-hydrogen production. Comparing open-loop and closed-loop simulation results shows that controlling the substrate concentration increases hydrogen production by 90%.
