Background: Campylobacter species are the main food-borne pathogens which could cause gastroenteritis in humans. Contaminated chicken products have been documented as the primary sources of Campylobacter transmission to human. This study was done to test raw chicken meat products retailed in local markets in Tehran, Iran for the presence of Campylobacter coli and Campylobacter jejuni species.
Materials and methods: A total of 70 raw chicken meat samples were collected during a three-month study. All the Campylobacter species were identified by biochemical and species-specific polymerase chain reaction (PCR). These isolates were investigated further to examine their potential virulence factors.
Results: Campylobacter spp. were detected in 56% of the isolates and identified as C. coli. The results indicated that all of the isolates were positive for cadF, cdtA, iam genes. On the other hand, none of the isolates were positive for flaA and pladA virulence genes.
Conclusion: Overall, the results showed that Campylobacter species were common contaminants in chicken meat, which should be screened for the presence of virulence determinants and for their involvement in food-borne diseases.

Supply chain Integration importance leads to this believe that some scholars express that the whole concept of supply chain management is derived from integration. Providing the basis for creation and effective continuation of supply chain management requires the recognition of main factors affecting the integration. Studies reveal that the organizations with higher levels of social capital are more successful than their rivals. So, the purpose of this study is to surveying Social Capital Influence on Supply Chain Integration. Considering the purpose, this study is applied research, and based on its research methodology, it is a correlation descriptive, and it is specifically based on the structural equation models. The population consisted of 435 organizations in food industry of Fars province in Iran, and via employing stratified sampling, 124 executives related to supply chain management were selected and the questionnaires were distributed and collected data were analyzed. This model suggests that five factors influence Supply Chain Integration, and the purpose of the research was to investigate the influence of social capital on these factors. The results indicated that the social capital has positive and direct relation with integration, communication pattern, trust and commitment and has no direct relation with power and attitude.

Background: Human papillomavirus (HPV) is one of the most common causes of sexually transmitted disease (STD) in humans. HPV is associated with gynecologic malignancy and cervical cancer among women worldwide. In the current study we sought to determine the prevalence rate of HPV in Iranian women identified with cervical infections.
Materials and Methods:  Prevalence rate of HPV in Iran was investigated from 2000-2016 using several databases including Medline, Web of Science, Embase, Google Scholar, Iranmedex, and Scientific Information Database. Statistical analysis was performed by Comprehensive Meta-Analysis (V2.2, Biostat) software. Random effects models were used by taking into account the possibility of the heterogeneity between the studies, which was tested through the Cochran’s Q-statistic.
Results: The meta-analyses showed that the prevalence rate of HPV infections was 38.6 % (95% CI, 27.9-50.5) among Iranian women with cervical infections. The further stratified analyses indicated that the prevalence rate of HPV was higher in the studies conducted during the 2000-2008 years.
Conclusion: The results of the present study underscore the need for further enforcement of STD control strategies in Iran. Establishing advanced diagnostic facilities for HPV, vaccination of high risk groups, and continuous monitoring of HPV are recommended for HPV prevention and control.

The phytoremediation capability in Pb removal from the contaminated soils by three native seedlings species (Acer cappadocicum, Fraxinus excelsior and Thuja orientalis) and one exotic species (Cupressus arizonica) were compared. The seedlings were grown in Pb contaminated soils at 0, 100, 200, 300, 400 and 500 mg kg^-1 concentrations for 6 months (Mar 21 to Sept. 22, 2015), after which the biomass allocation and Pb accumulation in tissues of root, stem, and leaf were assessed. The results showed that the higher Pb levels (400 and 500 mg kg^-1 soil) caused significant reduction in growth in all species, but this inhibition was less marked in the two conifer (T. orientalis and C. arizonica) compared to the two broad-leaf seedlings (A. cappadocicum and F. excelsior). Pb concentration in different tissues of seedlings increased with its increase in the soil. Further, Pb accumulation in the conifers was twice higher than that of the broad-leave species. Therefore, this study suggests that the two conifer species (P. orientalis and C. arizonica) can be used for phytoremediation, although further research is needed to make a final decision.

As a light verb, the verb “∫odan” contributes in the structure of a wide range of verbs and forms different applied concepts, including the expression of the change of state. In the French language, there are many different verbs and structures, which could be known as equivalents of the verb “∫odan”  for expressing the change of state. Therefore, incorrect use of any of these equivalents is a great concern for Iranian learners, and usually leads to misunderstandings. This paper will firstly study the two verbs, “∫odan” and “devenir” in Persian and French languages, respectively. Then we will introduce the equivalents of the verb “∫odan” in French language. Next the verb “devenir” will be studied in contrast with other French verbs, which express the change of state. Finally, the aspectual values of the verb “∫odan” and its equivalents in French language will be dealt with.

One of the analyzable concepts in discourse is value and valuer; valuer determines other valuesˊ occurrence, and other values are formed and oriented in its shadows. This research using analytical method and semiotique approach, tries to analyze interactivity and contrasting of value systems of discourse, as we as the formation of “power and reputation” valuer and the role of emotional conditions that are dissociated in this formation process. At the end and after analyzing Rostam and Sohrab discourse systems, we will see that “power and reputation” are values that the basis of value system of discourse is based upon them but the powerful presence of affection runs up against this valuer formation process. Therefore, narrative program of subjective agent to access the value object (meaning) is subject to change. Also object value changes its position and becomes an impediment to achieve the object value. Also using emotional process pattern to show disappointment and regret formation in Rostam after Sohrab dead, his critical condition in the story, and fear of being judged by the addressee, the effort he has made to maintain his ideological position and release himself from this situation is the main achievement of this article.

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%.
