Abstract
Background: Distillery’s vinasse wastewater is problematic to be easily disposed of in environment due to its high BOD and COD content which imposes a great deal of costs on plant. The main aim of this scientific and applied research is reducing the organic load of distillery’s vinasse wastewater via concentration technology.
Method: In this research, concentration of vinasse technology was used for reduction of organic load and removing color and odor of its wastewater. In this process, it was considered three evaporators and three separators. The raw wastewater was passed through from a phase with higher pressure into the other phases with lower pressure. The effluent form of each phase was sampled and the COD and BOD factors were evaluated.
Results: The results revealed that the COD reduction for the first, second and third phases were 68.98, 85.68 and 99.97 percent respectively and this reduction for BOD factor were 68.75, 85.68 and 99.97 percent respectively. The odor and color of raw wastewater were removed step by step by passing through first to three phases.
Conclusion: C oncentration technology has a perfect efficiency in reducing organic load and removing odor and color of distillery’s vinasse wastewater. Considering production of feed and also bio-fuel as by-products, it can be concluded that this treatment process can be used for treatment of distillery’s vinasse wastewater and similar plants.

Abstract
Background: Precise determination of organic load is one of the major and important parameters in selecting appropriate treatment process for industrial and domestic wastewaters . Performing chemical oxygen demand (COD) test in real samples is always subject to interferences, insufficient sample digestion and consuming high levels of chemical pollutants. The main aim of this scientific and applied research is modification of digesting system in COD test with silver nano particles for determination of organic load in effluent of pharmaceutical industries
Method: In this research silver nano-particles with 20nm in average size was used instead of silver sulfate in COD test. Optimizing some parameters such as digestion time, digestion temperature and catalyst dose was considered and the entire figure of merits was calculated for theproposed method. Then in optimized condition, the COD of pharmaceutical wastewater including domestic, industrial and mixed wastewaters were determined and their results were compared with the reference method.
Results: The results reveal that with only 16 percent of silver mass in reference method, high efficient and throughput results can be obtained for digestion of pharmaceutical wastewater and some slow-digesting chemicals. Minimum level investigations for digestion time and temperature reveal that in optimized condition and in presence of silver nano particles, the digestion process can be completed in 120 min and 150 ◦ C respectively. The proposed method enjoyed a 4.03 in mean of RSD% and 5.06 in relative error (n=12) which were better than the reference method. The limit of detection (LOD) and limit of quantification (LOQ) was 5.0 and 15.0 mg/l respectively with a 15-300 mg/l dynamic linear range.
Conclusion: Considering the efficiency of deterministic COD system based on digesting of organic compounds in the presence of silver nano particles for determination of organic load in pharmaceutical wastewater samples, as well as having high repeatability, compatibility with reference method, high dynamic range, consuming very low levels of silver mass and more environmental compatibility, it can be concluded that this test method can be used for determination of organic load in pharmaceutical wastewater and similar industries.

Abstract
Background: Consumption of dairy products in teenagers is very important for achieving optimum growth. Accordingly, the related government offices have distributed free-milk in schools in recent years. This study was designed to determine the acceptance of this intervention among the girl high schools in Yazd.
Methods: In this cross-sectional study, 703 students were selected randomly from the two educational regions of Yazd city. Data were collected by demographic questionnaire and questionnaires about the number of weekly consumed milks, knowledge and attitude. Data were then analyzed by SPSS version 16.
Results: The results showed that 37% of the students did not consume milk at all. There was no correlation between the knowledge and acceptance of milk although there was a correlation between the attitude and acceptance of milk among the students. Among those who had consumed milk, 63 % noted benefits of milk for their health as the reason for its consumption. Of the students who had not consumed milk, 64% did not drink it for its bad taste.
Conclusion: Considering the results, acceptance of distributed milk was not good and according to this study, the major reason of not using distributed milk was its undesirable flavor. Therefore enhancement of quality and taste of milk distributed by the government can help boosting the student's interest to consume it and to obtain most advantage of the program.

Abstract
Introduction: Type two Diabetes is one of the major causes of mortality and its prevalence is increasing around the world. It is widely accepted that diabetes is an oxidative disease. One of the antioxidants used in oxidative diseases is CoQ10.The aim of this study is to find out the effect of CoQ10 on insulin resistance and glycaemic control of patients with type two diabetes.
Methods: This is a double blind randomized controlled clinical trial which was conducted on 70 type 2 diabetic patients in Yazd Diabetes Research Center in 2011.The diabetic patients were randomly divided into two groups, CoQ10 and placebo. The Two groups took two capsules containing 100mg CoQ10 or placebo every day for 12 weeks. Blood glucose and insulin resistance were measured before and after the trial.
Results: Sixty two patients completed the trial. There was no significant difference between the mean of fasting blood glucose, median insulin and median secretion of the beta cells between two groups after the trial. The mean difference of Insulin sensitivity change was significantly greater in CoQ10 group (12.1+67.1vs -19.1+50.1 P<0.05).The median difference of HOMA (insulin resistance) between two groups after the trial was significant (P<0.05).
Conclusion: This study revealed that CoQ10 supplementation significantly increases insulin sensitivity and decreases insulin resistance in type 2 diabetes. Regarding the results of this study, supplementation with CoQ10 can be recommended for diabetic patients.
