Abstract:
Background and objective: Most important risky behaviors of health is inadequate diet, physical inactivity and smoking. The aim of this case control study was survey of relation between lifestyle of hypertension patients and some risky behaviors in patients referred to health centers of Ilam province.
Materials and Methods: In this case control study 200 hypertension patients and 200 people as a control group referred to the health centers of Ilam province selected by simple random sampling. Both groups completed the HPLP2 questionnaire. The data were analyzed by SPSS software and mann Whitney and cross kalwalis test.
Results: In relation to smoking, 10/9% of cases and 25/5% of the control group were smoking cigarettes or hookah. About oil consumption in food in control group 15/1% tend to eat low-fat foods, 53/6% moderate and 12.30% of fatty foods that the number of cases were 27/9%, 41/8% and 30/2 respectively. The mood of 46/4% of control groups was calm, 44/3%, sometimes angry and 9/4% very angry, this percent for case group was 39/9%, 44/7% and 13/9%, respectively.
Conclusion: According to the results and higher rates of smoking and high fat and salty food in control group compared to the case group, its seems this deferent related to the educational program for case group about dangers of smoking and high-fat diet and salt food. Therefore it is necessary to have educational intervention for other people.

FA
Water treatment plays a vital role in the delivery of safe and effective hemodialysis (HD). Ensuring that water quality meets the American Association for the Advancement of Medical Instrumentation standards and recommendations (or equivalent) is necessary to reduce the incidence of chemical hazards and endotoxemia associated with the use of water for HD. This review will discuss the principles of water treatment for HD, the essential components of water purification, the recommended system monitoring and maintenance procedures, and some of the historical incidents of adverse reactions that resulted from the use of contaminated dialysis water.

FA
Abstract
Introduction: Pregnancy and being mother, is one of the enjoyable and evolutionary life of women and often is within stress and depression. Regarding to these undesirable consequences on mother and fetus, this research has been done in the goal of “Exploring of Depression, Anxiety and Stress in Pregnant Women Referred to Health Centers of Urmia.
Material and method: this research has been in descriptive-analytic form. Sample members are 350 of pregnant women who referred to rural health centers of Urmia in 2016, Sampling has been done by random cluster sampling. Collection information tool was questioner in two parts, demography and questions of depression, anxiety, and stress (DASS 21). Questioner was distributed between pregnant women and they answered without any intervention of author except of they had been guided about goals of research. Data were transformed to SPSS16 software and analyzed by Chi-square tests and Pearson correlation coefficient. Meaningful level was in 0.05.
Results: findings of research show that depression, anxiety, and stress rate is 31.7%, 32.5%, 49.1%, respectively. There is a positive and significance relation between demographic T education, job, and pregnant age with depression, anxiety, and stress rate. Also, there is direct and significance correlation between depression, anxiety, and stress.
Discussion and conclusion: according to results of current research, social support is one of the main factors in decreasing of depression, anxiety, and stress.

Background and Objective: Previous studies have shown that poor nutrition may have a negative impact on cognitive function in children. This study aimed to assess the dietary intake of preschool children in kindergartens in Tehran and to determine the amount of possible correlation of dietary intake with cognitive development.
Material and Methods: the population study was all 5 to 6 years old children of preschools in Tehran who were supported by Welfare Organization in the year 2015-2016. Sampling was done using the multi-stage cluster random method, and in this way, one hundred subjects were randomly selected. Information on dietary intake collected using the food frequency questionnaire (FFQ) and cognitive development was assessed using Piaget test. Data analyzed using the t-test, Friedman test, and multivariate regression.
Results: Amounts of vegetables and fruits intake were not desirable in pre-school children. Mean score of the first part of Piaget's test (3.27) was more than the second part (2.45). The correlation coefficient of the dietary intake and cognitive development of children was 0.213. Approximately, 4.5% of the variance in children's cognitive development is explained by their kind of dietary intake.
Conclusion: The results of this study show that the dietary intake and cognitive development in pre-school children are correlated and the amount of this association is 4.5%.

Abstract
Background: Wastewater from factories and manufacturing centers because of various compounds, complicates the process of wastewater treatment. Among this industries, the textile, paper pulp, food, pharmacy and leather industry due to consumption of various types of chemicals are the most important importers of color pollutants to environment, which have harmful effects on the natural environment. The aim of this study is investigate of efficiency of ash and powder Rosewater Wastes in removal of Reactive Red 198 from aqueous solutions.
Methods: In this experimental study, after the preparing of powder and ash Rosewater Wastes absorbent, the effect of various parameters of operation such as pH (3-10), the initial concentration of dye (25, 50, 100 and 300 mg/L), contact time (5-180 minutes) and absorbent dose (0.05- 0.6 gr/100 ml) were studied. Finally the results were analyzed by kinetics and isotherm modeling.
Results: In this study, equilibrium time of powder and ash Rosewater Wastes Obtained 60 and 45 minutes respectively. The Maximum efficiency of absorbent powder and ash was obtained 68 and 89 percent, respectively, at pH 3, contact time of equilibrium and adsorbent dosage 0.4 gr/100 ml. isotherm studies matched with Freundlich isotherm models for both absorbents. Kinetic equations followed the pseudo-second of the model better.
Conclusion: The results showed that Powder and ash of Rosewater Wastes can be effective in removal of Reactive Red 198 and be cause a significant increase in absorption of capacity. Therefore according to Enormous resources of Rosewater Wastes in Iran, these cheap and available resources can be used to remove color pollutants from aqueous solutions.

Introduction
Dyes and heavy metals are hazardous pollutants often found together in wastewaters of textile industries; these pollutants have a significant ecological impact on the ecosystem and can modify the physical and chemical properties of water affecting the aquatic flora and fauna.
Methods
This fundamental-applied study was done on lab scale. Effects of various factors including dye initial concentration(5-50 mg/L), Cu initial concentration(1-10 mg/L), pH(2-10), adsorbent dose(1-8 g/L), and contact time(5-90 min) in the sorption dye and Cu were determined by using sawdust Melia Azedarach tree. The study was designed to experiments the response surface methodology.
Result
The most performance in dye and Cu removal were gained 98.03%, and 99.90% respectively. Increasing adsorbent dose showed the most positive effect, whereas initial dye concentration can cause performance falling on dye removal. Also, increasing pH showed the most positive effect, whereas initial dye concentration can cause performance falling on Cu removal. In this study, the data analysis of isotherm studies is more compatible with Langmuir model. An R2 value in Langmuir isotherm was determined 0.994 for dye and 0.9712 for Cu. Furthermore, the kinetic results showed the best fit with pseudo-second-order model. Show the R2 value determined same and equal amounts of 9998/0 for dye and Cu.
Conclusion
Sawdust as an effective method used in dye and heavy metal removal in aqueous solution.
