Teaching is a profession which is intermingled with emotional relationships. Teachers’ relationships with their classes have been shown to positively influence their performance. However, despite the novelty of the concept of teacher-class relationship (TCR) in the field of applied linguistics, examining the relationship between language teachers with the whole class has not received due attention. To shed more light on this novel concept and its antecedents, the present study aimed to investigate the role of psychological well-being, foreign language teaching enjoyment and work engagement in the TCR of language teachers. A sample of 428 English as a foreign language (EFL) teachers participated in the study by completing four online questionnaires, namely the Teacher-Class Relationship Scale, the Psychological Well-being at Work (PWBW) Scale, the Foreign Language Teaching Scale (FLTES), and the Engaged Teacher Scale (ETS). The results of structural equation modeling (SEM) indicated that EFL teachers’ psychological well-being, foreign language teaching enjoyment and work engagement were strong predictors of their TCR. In addition, it was revealed that work engagement was the strongest predictor. The findings were discussed regarding the significance of developing EFL teachers’ TCR. This study suggests that EFL teachers with high level of well-being who enjoy their profession and have dedication to their job are more likely to build strong relationships with their classes. Finally, suggestions for future research were provided.

     The Oriental hornet, Vespa orientalis L. (Hymenoptera: Vespidae) is one of the most important and serious enemies of honeybees. In this study, the annual population dynamics and daily activity rhythm of Oriental hornet were examined, based on the number of adults trapped in an apiary located in Ahvaz (southwest of Iran) during a period of two years (January 2021 to December 2022). Samplings were performed using the box traps available in the market. The bait used in the traps was fresh chicken liver, with the traps checked daily in four time periods. The results revealed that the first overwintering queens (gynes) emerged in March and two population peaks of newly emerged hornet workers occurred during the year, one in July and the other in October. In late November and early December, no adult hornet was trapped. The daily activity rhythm of adult hornets was observed mostly during 9 - 12, almost twice as much as in the afternoon period (12 - 15). The lowest activity was recorded in the evening period and night (6 pm - 9 am). During both years of sampling, the seasonal abundance of adult hornets displayed a significant positive correlation with air temperature and a significant negative correlation with relative humidity. By comparing the result of our findings with other studies performed in the same and different climate zones, it can be hoped to present effective methods to control the population of V. orientalis, especially in areas that have extensive beekeeping.

Background:Accumulative research is in progress to clarify clinical aspects of GBV-C. The possibility of interaction between HCV and GBV-C as well as its consequence on development of liver diseases is the most important clinical aspect which encourages researchers to develop a rapid and cost effective technique for simultaneous detection of both viruses. Methods: In this study, a SYBR Green real time multiplex RT-PCR technique as a new economical and sensitive method was designed and validated for simultaneous detection of HCV/GBV-C in HCV positive plasma samples. SYBR green real time RT-PCR technique optimization was performed separately for each virus. Multiplex PCR was established next. Standard sera with known concentrations of HCV RNA and dual HCV/GBV-C positive control samples along with negative control samples were used to validate the assay. Results and Conclusions:  Fifty six non cirrhotic HCV positive plasma samples [29 of genotype 3a and 27 of genotype 1a] were collected from patients before receiving treatment. 20.6% of genotype 3a and 18.7% of genotype 1a showed HCV/GBV-C co-infection. As a result, 19.6% of 56 samples had HCV/GBV-C co-infection that was compatible with other results from all over the world. SYBR Green real time multiplex RT-PCR technique can be used to detect HCV/GBV-C co-infection in plasma samples. Furthermore, with application of this method more time and cost could be saved in clinical-research settings.

Background and Objectives:HBV and HTLV-I are life threatening infectious agents in patients who receive blood and blood products. Although serological methods have been proved to be useful, detection of these viruses has remained a challengingissue due to the many obstacles. By the advent of Nucleic Acid Testing methods, especially in multiplex format, more precise detection is possible.The objective of this study was to develop a reliable, rapid and cost- effective method tosimultaneously detect HBV and HTLV-I. Materials and Methods: We have developed a multiplex Real time-PCR assay for simultaneous detection of HBV and HTLV-I. Primer sets were designed for highly conserved regions of genome of each virus. Using these primers and standard plasmids, we determined the limit of detection, clinical and analytical specificity and sensitivity of the assay. Monoplex and multiplex Real-time PCRs were performed. Results: Analytical sensitivity was considered to be 1000 and 100 copies/ml for HBV and HTLV-I, respectively. High concentration of one virus had no adverse effect on detection of t low concentrations of the other one. By analyzing 30 samples, clinical sensitivity of the assay was determined to be 87% and 96% for HBV and HTLV-I, respectively. Using different viral and human genome samples, the specificity of the assay was verified to be 100%. Conclusions:We have developed a reliable, rapid and cost effective method tosimultaneously detect HBV and HTLV-I.Our results indicatedthe high capability of this simple and rapid method for detecting these viruses in clinical samples.

Previously, neighborhood units were considered as the first identity unit of cities and the most important base of citizen’s social relationships, however recently they have been lost in the shadow of new urban developments. Nowadays, the quantity of citizen’s relationships has been increased but it happened at the cost of quality reduction in social relationships alongside replacement with virtual relationships. It seems that the identity and cultural structure of urban society are being threatened by new urbanism development and loss of their original functions in Iran. This is the result of shrinkage in the function of neighborhood centers and interior public spaces in the neighborhood units. On the other hand, green spaces and valuable natural countryside of cities are destroyed because of population increasing, industrial development and undefined urban expansion. Not only reduction in appropriate urban green spaces has suppressed their effects on urban pollutions but also limited the recreational and social open spaces in the cities. Design and construction of neighborhood parks as a part of urban green spaces, are among the most important issues in the design and planning of contemporary urbanism. In the developing countries such as Iran, establishment of new neighborhood parks is part of the Improvement of minimum necessary urban green spaces, but the effect of such green spaces on the type and quality of citizens’ relationships has not been deeply noticed. Noticing the” neighborhood unit” as an informant unit of city is basically one of the fundamental strategies for solving this problem. Revitalization of old neighborhood unit centers in the form of new neighborhood parks and using the potential of neighborhood green spaces could develop social relationship in the neighborhood units. This research aims to answer two questions: 1) What is the function of neighborhood parks in the social relationship quality of neighborhood communities; and 2) How the neighborhood parks can be used for development of neighborhood social relationships. Two successful samples from the developed countries and one successful sample from Iran were selected for analytical –descriptive analysis of the subject. Besides analyzing the operation quality of these parks in urban spaces, different impacts of such green spaces on neighborhood social relationships were studied. The results showed that, for increasing of neighborhood social relationships, the appropriate conditions for increasing the presence time of people in the parks must be provided at first. Some of these conditions such as easy accessibility, attractiveness, etc have impact on peoples’ attraction to the parks, and some others such as physiological comfort, sense of security, natural scenes, etc have impact on people’s presence time in the park. Suitable tactics for increasing interaction between people were stabilized; such as park furniture arrangement types, multiple and social activities and, good aggregation points. Based on the results of this study, appropriate strategies for the design of  neighborhood parks were developed.

The dust produced by the electric arc method in the ferrochrome factory contains high amounts of hexavalent chromium, which has a high solubility in water and causes high environmental pollution. The present research has proposed a new method for neutralization of hexavalent chromium present in ferrochrome dust in solution environment by using chemical precipitation method. After checking conventional and non-conventional additives for neutralization by co-precipitation method, Iron sulfate is added to the aforementioned wastewater before release into the environment as a reducing agent of hexavalent chromium to trivalent chromium. Next, calcium sulfate was used as a stable complex forming factor in the system to remove chromium. XRD and XRF analyzes were used to characterize the dust and UV-Visible to determine the amount of chromium removed from the wastewater. The results showed that for 100 g/l of dust dissolved in water, adding 30 g of iron sulfate in the first stage and 20 g of calcium sulfate in the second stage reduces the content of hexavalent chromium from high values to below 10 ppm. Easy, high speed, cheapness and availability of additives are the merits of this method.

Striga hermonthica is a noxious, obligate hemi-parasite of cereal grasses that causes severe grain yield loss in susceptible maize cultivars in Africa. The development of host plant resistance is one of the most practical Stiga control strategies. In this study experiments on 36 maize inbred lines were conducted in pots and in field during the two rainy seasons of 2009 at Kibos and Alupe stations in Kenya. This study was carried out in order to determine the variation in Striga emergence, and the correlation between the attachments of the parasite to the roots. Significant differences (P < 0.001) were detected among the inbred lines for grain yield under Striga-free environment. The Striga damage rating (SDR) was significant (P < 0.05) among the inbred lines. A highly significant and negative correlation coefficient was observed between grain yield and Striga damage rating (r = - 0.67). Positive correlation coefficients were observed between grain yield and ear aspect (r = 0.46) and plant aspect (r = 0.75), respectively. For the experiment in pots, highly significant differences (P < 0.01) were observed among the inbred lines for Striga resistance traits. Striga attachments were found to be correlated with the number of emerged Striga plants. A significant correlation was found between Striga attachments and Striga counts in pots at the 10^th week after planting (WAP) (r = 0.25) and the 14^th WAP (r = 0.31). Inbred lines JI-30-19 and OSU231//56/44-6-4-17-3 were identified as the most resistant lines as they consistently performed well in both Striga-free and Striga-infested environments. These inbred lines could be used for breeding Striga-resistant maize varieties.

Aims: Fatalistic employees take serious risks because they have limited knowledge of risks and accidents, leading them to under estimate the possibility of their occurrence. This research examined the effectiveness of safety training on changing employees’ fatalism with attention to the mediating role of attitude toward safety issues. Methods: 204 employees was selected according to the stratified random sampling method in Isfahan Steel Company, divided randomly into control group (n=103) and experimental group (n=101) and the questionnaires of safety attitude and fatalism were applied as data collection instruments. The data was collected before intervention, and educational intervention was then executed in four 90-minute sessions over four days. One month after intervention, post-test was performed and the collected data was analyzed using descriptive indexes, t- and F-tests. Findings: Results show that there was a significant statistical difference in average numbers of attitude toward safety issues and fatalism before and after training intervention (p<0.01). Also, mediation analysis indicated attitude toward safety issues mediated the effect of safety trainings on fatalism (p>0.05). Therefore, safety training only by promoting workers’ safety attitudes can change the fatalistic beliefs among employees. Conclusion: By understanding relationship between fatalism and safety attitude, it should be possible to improve the training of employees, such that are less likely to attribute accidents to chance or fate.

Demographic parameters of the ladybeetle, Serangium montazerii Fursch feeding on citrus whitefly, Dialeurodes citri Ashmead were determined on two host plants, Page tangerine and Thompson navel orange. This study was carried out under laboratory conditions (25 ± 1 °C and RH of 60 ± 5% and a photoperiod of 16: 8 h (L: D). Total pre-adult periods of the lady beetle were 20.84 ± 0.302, 19.27 ± 0.251days on Page tangerine and Thompson navel orange, respectively. The survivorship from egg to adult were very close to each other on the two host plants. The oviposition periods were 29.64 ± 0.905 and 33.36 ± 0.599 days and the total number of eggs per female (fecundity) were 457.14 ± 11.099 and 528.57 ± 12.369 on Page tangerine and Thompson orange, respectively. Peaks of reproductive value occurred at ages of 31 and 33 days when reared on Thompson navel orange and Page tangerine, respectively. The intrinsic rates of increase (r) on Thompson orange and on Page tangerine were 0.134 ± 0.063 and 0.126 ± 0.006d^-1 with no significant differences. The mean generation time (T) on these host plants were 39.03 ± 0.5 and 40.57 ± 0.46 days, respectively. It can be concluded that S. montazerii feeding on D. citri in general showed a slightly better reproductive performance on Thompson navel orange than on Page tangerine.

Acknowledging the strengths of the national curriculum, the present study aimed at evaluating its approach towards foreign language education from three perspectives: (1) analyzing the foreign language section of the national curriculum based on the methodological and theoretical underpinnings, and its internal consistency; (2) examining its content based on the basic assumptions mentioned in the literature for setting foreign language policies and (3) evaluating its content based on the macro-documents of the country. In so doing, first, the relevant sections of the national curriculum were analyzed. The results indicated that, although the foreign language section of the national curriculum has some strengths such as a move toward decentralization and increase in hours of instruction, it suffers from some weaknesses such as vagueness of the content and lack of consistency and connection among the aims of the instruction. In order to examine the document from the second perspective, 6 criteria that foreign language education policies should follow were extracted from the relevant literature, and the document was evaluated based on these criteria. The results indicated both consistencies and inconsistencies between the content of the document with these principles. The national curriculum, then, was evaluated to find its matches and mismatches with the policies and orientations of macro-documents. The results indicated that the foreign language section of the national curriculum cannot set the ground for achieving the goals proposed in the macro-documents of the country. Finally, the paper offers some guidelines for developing national English language curriculum.

It was not just the uneducated human in ancient times who believed in an invisible magic powers in the world, and people have always believed in “ANIMISM” and “FITSH”. From many long time ago, people used to think that some objects, animals, and sky and stars have these invisible magic powers.  Because of his little amount of knowledge, he had no chance of understanding the scientific rules that run the world. So he began to believe       in the influence of these invisible magic powers over his daily life in order to make reason for bad events of his life or even to prevent them. He had to adjust every little things of his life to these believes. In Iranian religion before Islam, like other ancient religions, many superstitions looked legal and rightful, and also believing in the influence of sky and stars on days and years;  in astrology, and in prediction  was very usual.  In this research, different kinds of prediction  according to the middle Persian texts will be studied: prediction based  on inspiration, influence of sky and stars on days and years, the things that should be done and not should be done on specific days, soothsaying texts based on numbers in a Zoroastrian Omen Manuscript, including: the  number omen with numbers1-5, the omen of JAMASP E HAKIM, and omen of ANAAMOL.

Unwillingness-to-communicatation in a foreign language (UTC) on the part of learners, which is a tendency to avoid oral communication, is one of the main problems of language teachers. In a way, if the source of this unwillingness is determined, language teachers can decide better about those students who seem reluctant in the communication and usually avoid interactions. Yet the extent of this unwillingness is not constant among different individuals and it can be the result of many diverse factors. This study has focused on the relationship between the students' personality traits and their UTC, and the role of gender in the levels of UTC. In so doing, two highly validated measures of NEO Five Factor Model (NEO-FFM) and UTC scale of unwillingness to communicate were administered to 250 participants from four universities. The results of step-wise multiple regression showed that, from the five factors of personality (extraversion, neuroticism, conscientiousness, openness to experience and agreeableness), extraversion was the best predictor of UTC. The second and the third predictive variables were neuroticism and conscientiousness, respectively. While extraversion and conscientiousness had a negative relationship with UTC, neuroticism had a positive correlation. Moreover, the results of t-test proved no significant difference between the two groups of males and females with respect to their levels of UTC. In the end, drawing on the relevant literature, the results of the study have been discussed and the importance of findings has been explicated for teachers and language teaching practitioners.

Fusarium graminearum is one of the most important causes of FHB or wheat scab in different part of the world. This fungus is able to produce widespread Trichothecene mycotoxins such as Nivalenol (NIV) and Deoxynivalenol (DON) which are harmful for both human and animals. To determine chemotypes of Trichothecene, a total of 100 isolates from different fields of Golestan province in Iran including Gorgan, Kordkuy, Bandaregaz, Gonbad, Minodasht, Kalaleh and Azadshahr were identified as F. graminearum using morphological features then 96 isolates were confirmed by polymerase chain reaction (PCR) assay using F. graminearum species-specific primers (Fg16F/Fg16R). Based on sequences of Tri13 gene involved in the mycotoxin biosynthetic pathway, PCR assays was used to detect Nivalenol (NIV) and Deoxynivalenol (DON) chemotypes. Of the 96 tested isolates with Tri13 PCR assays, 70 classified as NIV chemotype and the remaining 26 isolates as DON producers. These results indicated that NIV chemotype was the most dominant chemotype in studied zones. A greater proportion of NIV chemotype was found in Gorgan fields (P < 0.05, P < 0.0001), whereas greater proportion of DON was detected in Gorgan and Gonbad fields (P < 0.05, P < 0.0001). Chemotyping by PCR assay were confirmed using HPLC method. These results demonstrated that PCR assay and HPLC could be used as rapid, reliable and cost-effective methods for the detection and identification of mycotoxin-producing Fusarium-species and may thus help to develop strategies to avoid or reduce mycotoxin contamination of cereals.
