ABSTRACT
Background and objective: Milk and dairy industries wastewater are considered the most polluted effluents, and if discharged without treatment into the environment, can cause serious environmental problems. In this study, effects of aeration time and lime coagulant on SBR efficiency were investigated.
Materials and Method: Two Parallel reactors with a volume of 20 L was used. The examination was conducted in three steps. During these steps , effects of conventional aeration time, long aeration time and use of lime coagulant aim after 7h aerated on SBR performance were investigated, respectively.
Results and discussion: The results were shown an increase of aeration period can be effected on increase removal rate of COD, BOD NH4-N, and TP, respectively. And also this is indicated suitable efficiency for the removal of COD , BOD, NH4-N were created with a duty cycle 24h and aeration time of 7 h. Application of SBR system with the aeration time of 7h and injection of lime coagulant aim in the loading rate of 0.6 kg BOD/m3.day, provided the essential standards for the disposal of effluent into the water reservoirs.
Conclusion: Optimized SBR process can be provided to reach better effluent standards in less time in milk and dairy industries and also reduce time can decreases of operation costs.
Key words: Lime coagulant aim, Aeration time, milk and dairy industries wastewater

Introduction: influenza A (H1N1) disease is a serious viral disease which recently has been a pandemic. The purpose of this study is a determination of knowledge and attitude of students living in student accommodation and Iran University of Medical Sciences, about influenza A (H1N1) disease.
Methods: This cross-sectional research study (descriptive _ analytic) that the 150 students, the cluster sampling method (accommodation) and simple random (Students accommodation) were performed. Information gathering tools, including a questionnaire to 14 questions were knowledge and attitude. After collecting data using SPSS 19 statistical software and statistical analysis Chi-square and Pearson correlation coefficient, significance level (p<0/05) were analyzed.
Results: The knowledge of 55.3% and attitude of 60% of the students were moderate. There were significant relationships between knowledge with level of education and major (p =0.02 and p =0.02). A significant relationship was observed between attitude and major too (p =0.04). But there were not found significant relationships between knowledge with age and gender also between attitude with age, gender and level of education.
Conclusion: Knowledge and attitude of the students about influenza A (H1N1) disease wasn’t appropriate. Planning appropriate educational interventions to improve knowledge and attitude of the students about the disease according to their major and degree is suggested.

Background: Metal industries are of accident-prone industries. Todays the hazard assessment in order to hazard control is very important. Aim of this study was safety and occupational health risk assessment in a metal industry.
Methods: This cross-sectional study was conducted in 2014 in Isfahan. Firstly three jobs, forging and fittings cutting and finery press operators, which had highest rate of accidents was selected. Then each task was broken into its subtasks and finally risk assessment using Job Safety Analysis and William Fine methods conducted. Findings analyzed using descriptive and analytical statistics and controlling approaches was delivered.
Results: Assessments lead to identification of 21 hazards in forging, 9 in fittings cutting and 10 in finery press. Highest levels of risks were related to falling hot blocks, error in pushing foot pedal, hands strike to saw blades and environmental noise. Statistical Kruskal walis test showed that no statistical difference found among three jobs, both for Job Safety Analysis and William Fine.
Conclusion: The risk levels of each three jobs was worrying. It seems that applying controlling actions in order to eliminate or decline hazards level is necessary.

Breast cancer is the most common cancer in women worldwide. Current cancer treatments have multiple side effects, including damage to healthy cells, drug resistance and disease recurrence. Therefore, new therapeutic strategies are needed to achieve fewer toxicity and side effects.
Several studies suggest that phytochemicals could be considered as appropriate choices for cancer prevention and treatment. Resveratrol (trans-3,5,4-trihydroxystilbene) is a polyphenol found in many plant species such as grapes, raspberries, mulberries, peanuts and blueberries, containing a wide range of health benefits. Resveratrol not only induces apoptosis of tumor cells and inhibits inflammatory factor NF-κB, but also inhibits some of estrogen-receptor isoforms and prevents the progression of cancer.
Therefore, based on the available studies, resveratrol can be considered as one of the most promising candidates for cancer prevention and treatment and could be used after further investigations.

Introduction: Internet social networks as a place for the different segments of society, especially the youth have become. The aim of this study was survey of social networking usage and its relationship with the study status of students of Ilam universities 2015.
Material and Methods: In this cross-sectional study, 400 students of Ilam universities were selected by simple random sampling method. The data were collected which consists of three parts: demographic questions, questions the use of social networks and questions educational status. After data entrance to the SPSS software, the data were analyzed by Pearson correlation test, linear regression, ANOWA and chi-square test.
Results: The use of social networking in 25.5% of students at a high level, 63.8% on average and 10.8 % were low and 11% of students at the high school situation, 76% on average and 13 % as low. Between the use of social networks and there was no significant correlation between students' academic achievement (P>0.05) . Between the use of social networks and student age, gender and occupation there was a significant relationship mother students (P<0.05). But between the use of social networks and other demographic variables, there was no significant relationship (P>0.05).
Conclusion: Direct correlation between the use of social networks and the students there, this correlation was incomplete and of low intensity. This means that the use of social networks is more intense than the lower educational status and this association was not significant. It seems that due to the expansion of interpersonal communication, use of social networks has created for student satisfaction and their users are increasing day by day.

Methods: This descriptive-analytic study was from type of practical researches that was done cross-sectional method in 2015. The study population consisted of urban and rural health centers implementing the National Plan of FamilyMedicin (20 health centers). According to the class random sampling method and based on the volume of clients for each center, the number of 469 questionnaires were completed and returned. To collect data, were used standard questionnaire SERVQUAL.Data were analyzed by SPSS 11.
Results: The mean and standard deviation of the difference between expectations and perceptions of service quality gap indicated that patients in all five dimensions have positive expectations and lower than the current situation. The highest average score in expectations related to the assurance dimension 64/5 ± 52/27 and the lowest score on the physical dimension 21/4 ± 47/18 respectively. The highest average score in perceptions related to the assurance and the lowest score was related to empathy. The results showed that in all dimensions average expected obtained higher than current situation and this difference is significant in all dimensions (p<0.001).
