Q fever is endemic zoonotic worldwide diseases which caused by Coxiella burnetii. This pathogen can be infecting domestic and wild ruminants, companion animals, insects and humans. Ruminants are the primary reservoirs of C. burnetii. A variety of tick species also act as reservoirs or vectors for disease via bite, shedding or vertical transmission. Dogs and cats could be infected via inhalation or ingestion of aerosol from milk, aborted fetuses or carcasses of infected animals. Some reports indicated that pet owners could be infected after inhalation of aerosol which shed during parturition or abortion by infected dogs and cats. The aim of this study was to determine the presence of C. burnetii in the blood samples of stray cats in Kerman city (Southeast Iran) using a nested Trans-PCR assay.
Blood samples were obtained from sixty stray cats which were trapped from different parts of Kerman city from May to September of 2015. DNA extraction was done using extraction kit (G-spin ¡South Korea) and specimens were refrigerated at -18 oC. Detection of C. burnetii was conducted by nested Trans-PCR assay using the specific primers.
Seven out of 60 (11.66%) samples were positive by nested Trans-PCR.
Our data showed that cats can be considered as the reservoirs for C. burnetii and noted zoonotic importance of these populations. As Q fever is an endemic disease in farm animal in Iran specially Kerman district, efforts should be focused on understanding the role and pathogenic importance of companion animals in transmission of Q fever to human population.

Dust deposited on the leaves of trees can be effectively used as the monitors of polycyclic aromatic hydrocarbons (PAHs). The dust deposited on the leaves can be used as an appropriate index for evaluating PAHs in the atmosphere. This research was conducted to determine the origin and health risk assessment of PAHs accumulated on the leaves of trees in the city of Ahvaz. For this purpose, samples were taken at leaves on 10 points with different land uses including industrial, recreational, high-traffic and residential ones. After preparation, to determine the type and concentration of PAHs, the compounds were analyzed by GC-MS. The results showed that 15 types of PAHs had been identified from 16 important compounds identified by EPA in the dust samples. The concentration of compounds was the range of 3.3-110 microgram per kilogram. The maximum and minimum of PAHs carcinogenic in particles trapped on leaves were in the Kut-Abdolah with 530 ppb and Shahrvand Park Station with 5.13 ppb, respectively. Also, the average relative of LMW/HMW in the aromatics contained in the deposition of particles on trees was 0.5; further the analysis of the main components of aromatic hydrocarbons (PAHs) showed that there was  no specific source for these compounds in Ahvaz, and these compounds could be from fossil fuels, urban traffic, natural gas,   generally showing a pyrogenic origin.

The oil, gas, and petrochemical industries, as one of the largest sources of environmental pollutants, have different types and levels of pollution depending on the type of input materials, process steps, and output products. Various stages of exploration, extraction and processing of oil and gas have many environmental effects, such as those on soil, air, water, creatures, plants, and even humans. In this paper, a failure mode and effects analysis (FMEA) is employed to identify failures and environmental risks in an oil and gas exploitation plant. Dempster–Shafer (DS) theory of evidence is then proposed for environmental risk assessment due to its effectiveness in dealing with uncertain and subjective information. The assesments of experts and their confidence levels of their responses are employed to construct the basic probability assignments (BPA) in DS theory of evidence. Furthermore, a new weighting method is proposed to obtain the discounted BPA which reduces the uncertainty in the information sources and improves the quality of information before combining different sources of information. Finally, the proposed method is applied to an oil and gas exploitation plant to assess environmental risks.

In this study assesment of anthropometric indicators in children under 6 yr, in western region of Tehran, was evaluated during the month of sept. 1996.
The prevalence of failure in weight for height and height for age indicators was considered according to age groups.
The failure of weight for height (wasting) showed the highest prevalence among children in 48-59 month age group (21.29%).
The failure of height for age (stunting) showed the highest prevalence in under 12 month and 12-23 month age groups 19.2% and 17.3% respectively.

According to increase in quality and quantity of Continuing Medical Education(CME) Programms, assesment of educational needs is a part of research priorities in Education Development Centers(EDC).Due to lacking studies in this field among dentists, we decide to evaluate dentists opinion regarding qualiy and quantity of current Continuing Medical Education program. This descriptive study was done Among Zanjan providence General Dentists. 60 dentists fill the questionaire regarding qualitative and quantitative assesment of Continuing Medical Education.The data was analyzed by SPSS 20. This study was conducted on 64% male and 36% female with mean age of 41.49±7.49. They(52.5%) claimed that the most effective way to increase efficacy of these courses is to ask great instructors to do the courses and also the best method of performance is patient based method. The main problem of the dentists attending courses was thelong interval between the CME courses.Most of the dentists agreed to have 5-10 programms in a year.59.8 percent of them was agree with virtual internet based continuing education programms.they also claimed that there is a great balance between their educational needs and the programms. Because of the acceptance of virtual programms among most of the dentists,it is recommended to have virtual programms base on their educational demands

The association between C-reactive protein, homocysteine, uric acid levels and cardiovascular risk have been debated for decades. Resistin is a newly discovered adipocyte derived cytokine. Smoking besides its effect on atherosclerosis, is shown to alter adipocytokine levels. Bearing in mind, these complex relationship of resistin with smoking, C-reactive protein, homocysteine and uric acid, we planned to investigate the association of resistin and these cardiovascular risk factors in smoker and non-smoker subjects. We conducted a cross-sectional randomized study including 52 smoking and 33 non-smoking men. After making comparisons of C-reactive protein, homocysteine, uric acid and resistin between the two groups, we classified the subjects according to their insulin resistance and body mass and made again the comparisons. Resistin levels were higher in smokers than in non-smokers (p<0.001) and also in insulin resistant than in non-insulin resistant smokers (p<0.05). Resistin levels were indifferent in non-smokers as insulin resistance was concerned and in smoker or non-smokers as body mass index was concerned. As all subjects were grouped based on homeostasis model assesment index and body mass index, neither C-reactive protein nor homocysteine and uric acid levels differred. We found that smoking may have influence on resistin levels and in smokers, insulin resistance is related to resistin levels, but in smoker and non-smokers body mass may not have any association with resistin. Resistin also may not have a role in C-reactive protein, homocysteine and uric acid levels both in smokers and non-smokers.

The purpose of this paper was the analysis of share prices of the firms offered in "TSE" under the privatization program, with consideration of Theoretical and Scientific models, in order to specify the extent of comparability of these prices with the theoreticalones. The criterion used for the assesment of the comparability of the bas-price with the theoretical price is that; market price in creases should be supported by the firm's profitability. The research has been conducted en the basis of inductive & deductive analysis, with a statistical sample of 40 firms, which their stocks has been accepted and traded by the end of 1370. The results indicate that the share initial pricing of the firms is not based on the scientific grounds and has no compatibility with further market events. The present pricing mechanism, from the economic, social & accenting viewpoints, does not reflect accurate valuation of the shares.

Aim and Sustained attention can be evaluated through paper and pencil tasks. The purpose of the present study was to design a sustained attention test and evaluate its validity and reliability.
Methods and Materials: The present cross-sectional study was conducted on 230 elementary school students with the mean age of 9.09 ± 1.46 years (7-11 years). The Continuous Performance Test (CPT) and Persian Attention Registration Test (PART) were conducted on the subjects. The PART was repeated in 151 students after 4 to 6 weeks. The Pearson test was performed for the assesment of test-retest reliability and concurrent validity between the two performances of the test and between CPT and PART results, repectively.
Findings: Errors of omission and commission had significant positive correlation in both measures. Errors of omission and commission and the total time of test with Pearson coefficients of0.886, 0.610, and 0.478, repectively, had a significant positive correlation in the two tests (P PART is a valid and reliable test for the evaluation of sustained attention.

Best Management Practices (BMPs) are implemented in a watershed to reduce the amount of non-point source pollutants transported to water bodies. However, an optimization algorithm is required to choose the efficient type, size, and location of BMPs for application in a watershed for improving the water quality. In this study, the Charged System Search, a well-known and powerful meta-heuristic optimization algorithm, as an optimization model and a semi-distributed hydrological model i.e. Soil and Water Assesment Tool (SWAT) were coupled to obtain cost-effective combination of different BMPs. To demonstrate the performance and applicability of the coupled model, it was utilized to Sofichai watershed upstream of the Alavian Reservoir in the northwestern part of Iran to compare four reduction levels of sediment, nitrate nitrogen and phosphate phosphorous loads at the watershed outlet.
