Di-n-butyl phthalate is widely used as plasticizer, which has been listed as PRIORITY POLLUTANT due to its toxic and ubiquitous characteristics. It is difficult to remove by the conventional wastewater treatment processes. In this paper, the feasibility of using Micrococcus sp. to bioaugment a sequencing batch reactor for degrading di-n-butyl phthalate (DBP) was investigated. The terminal restriction fragment length polymorphisms (T-RFLP) were used to analyze the variation of microbial community in the reactor. The experimental results showed that for the bioaugmented reactor, the removal efficiency of DBP was about 85% as compared to 25% of the control reactor when initial DBP concentration was 100 mg/L. The bioaugmentation not only enhanced the removal efficiency of target compound, but also shortened the start-up time of the reactor. The kinetics of DBP degradation conformed to the first-order model in both reactors. The T-RFLP analysis indicated the bacterial community changes in the acclimated activated sludge and the introduced Micrococcussp. during the operational process.

Sometimes people have PRIORITY to others due to having the right of PRIORITY In conducting a legal action or demanding the fulfilment of right of a certain property. Sometimes the legislator has considered it for some reason for some persons in a particular position. The right of PRIORITY is protected by the legislator, and sometimes it is explicitly forbidden to opposing contract with it. However, the guarantee of this ban, there are disagreements between jurists and lawyers in the cases stated. Some believe conclusion of opposing contract with PRIORITY is void,in contrast, some are considered valid, in the end, others they have chosen the middle solution and they believe that the deal is not affected. In the examples of PRIORITY, the overall conclusion is that opposing contract with PRIORITY is un enforceability to third party,Because these transactions have all the components of the contract, except that there is a barrier to their influence, and that obstacle is the right of PRIORITY of the beneficiary, which, in the event of the subsequent payment of his rights, automatic be valid. Accepting this guarantee solution will not only supply the rights of the rightful owner butalso the rights of the parties.

Complexity of health technologies and increased demands for health care services concomitant with globalization in health care and finite resources have resulted in shortcomings in health delivery and have raised issues regarding equity. Most people experience some sort of denial, delay, deflection, dilution, deterrent, or selection when need health care services and profit is going to be the prevailing variable. Policy makers struggle to circumvent these problems in different ways, none of which prevail across a broad range of health care system. Evidence indicates PRIORITY setting in health care services inevitably requires explicit criteria. A variety of criteria which have been used in different health care system are discussed, focusing on experiences in community participation and approaches for community appraisal. Adopting experience from health care system, and evaluation adapted to respect national values will strengthen the burgeoning health sector reform in Iran. According to worldwide health care principals it seems crucial to establish a regulatory health council to underpin the evidence based PRIORITY setting process in Iran.

Present research aimed to identify the needs of IRIPF employees as well as prioritizing their needs. To this aim, 3917 employees throughout the country filled out the need assessment questionnaire.Gathered data analyzed by qui square revealed that different ratio of employees fall into each one of the five need categories (p<0.001). The results also showed a reversed pyramid in which the needs of a higher percentage of employees fell into the higher need categories of self actualization, dignity, and social, whereas; the lower percentage of employees needs PRIORITY had to do with lower needs as safety, and physiological needs.

Background and aims: Prioritizing research fields prevents waste of budgets and increase efficacy of research. Paying attention to health of employees and workers is necessary for promoting health and sustainable development in the country. Therefore, this study was conducted to determine the research priorities in the field of occupational health in Iran.Methods: The present study was explorative and qualitative research. In order to determine the research priorities in the field of occupational health the COHRED model was used. Data collection was done by review of the literature, obtaining the views of experts (by interview and Delphi technique) and collecting statistics from relevant officials. PRIORITY setting was done in two stages and based on Delphi technique. In this research out of 70 identified research centers, 22 participated in the study. Descriptive statistics including mean (SD) and frequency (percentage) was used to analysis the data.Results: Results of this study showed that musculoskeletal disorders and injuries had the highest research PRIORITY in Iran. The occupation of workers in mine and industries had the highest research PRIORITY. Also three indicators of equity in service provision, work security and healthy life style had the highest research PRIORITY among the social determinants of health for workers.Conclusion: The research was an attempt to identify research priorities in different areas of occupational health research which can be used as a tool for decision makers in distribution of resources.
