Mesoporous manganese oxide nanoparticles were prepared using SBA-15 hard silica template (SBA-MnO2) and were investigated as electrode material for electrochemical pseudocapacitors. Also, for comparison, mesoporous manganese oxide nanoparticles were prepared using pluronic P123 copolymer as a soft template (P123-MnO2). Structural and morphological characterizations of the prepared manganese oxide nanostructured materials were conducted using X-ray diffraction (XRD), nitrogen absorption/desorption test, scanning electron microscope (SEM) and transmission electron microscope (TEM). In addition, electrochemical investigations of the electrode materials were performed using cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) examinations. The results showed that the SBA-MnO2 active material has a higher specific capacitance (1200 F g-1 in a current density of 1 A g-1) than the P123-MnO2 material (1200 F g-1 in a current density of 1 A g-1) due to its higher specific surface area and more porous structure. Therefore, the mesoporous SBA-MnO2 active material can be introduced as a potential electrode material for high-performance electrochemical capacitors.

Differences in people's attitudes, tastes and beliefs make the emergence of differences in human relations inevitable, and indifference and lack of familiarity with the correct way of dealing with conflicts can cause irreparable damages. Based on this, it is necessary and important to know the effective measures to prevent or resolve disputes in the form of "conflict management". Since the Holy Qur'an is the most important source of study for the Islamic society, in the present study an attempt has been made to answer the question that; How is the process of conflict management from the perspective of the Holy Qur'an? Using the method of theme analysis and digging into the Holy Qur'an, the verses related to the subject should be identified and extracted. The findings of the research showed that conflict management from the perspective of the Holy Qur'an is a process that includes two stages before and after creating a conflict. In the pre-conflict stage, people need self-improvement to deal with ego and satanic provocations, and to gain knowledge of the inherent differences between people. And in the stage after creating a conflict, sequential strategies such as; Ignoring, focusing on commonalities, inviting to dialogue, referring to arbitration and finally insisting on vote and opinion should be taken into consideration. The results of the research show that the sequential navigation of the process steps introduced for conflict management can be a reliable and methodical tool for dealing with interpersonal and group disputes and conflicts.

Urbanization, growing population, and economic development cause a growing trend in waste generation of the world including our country. On the other hand, other concerns like landll limitation and pollutions of waste disposal, bring this matter to fore. In this paper, we are trying to represent a dierent approach in terms of systematic and managerial aspects of Solid Waste Management (SWM) using dynamic modeling for Household Waste Management (HWM), which contains an important part of current waste generation in Tehran. In terms of management, our new approach is concerned with addressing the issue of HWM in particular, such that the use of social and qualitative variables (such as culture,education,familysize,andimpactofadvertising budget and source waste separation on recycling level) and also economic variables such as in ation, per capita income, buying power and per capita consumption, increase our innovation in terms of systematic approach. Casual loop and ow diagram were drawn by Vensim software. In the last sections, we performed the model validationandvericationusingtheestablishmentofextreme conditions, reality check, logical boundaries for variables and matching with historical data. Considering socio-economic factors, simulation time period, and current delays dealing with our issue, we are trying to analyze the best policies for HWM in Tehran in order to achieve the best possible results in recycling cost, recycling ratio, and disposal ratio regarding budget limitation. One of the main problems in (WHM) is the pollution caused by the landll and the shortage of land for burial. Two solutions are proposed to deal with this problem: therstisincreasingofbudgettomakeculture and also advertising and planning to promote the consumption culture; the second is focusing on the planning and implementation of source waste separation. The model indicates the second solution is better than the rst.

Investigated the effects of beet (as a source of plant pigment) on rainbow trout skin discoloration experiment in a completely randomized design with 4 treatments and 3 replicates were performed. For this purpose, 240 fish (20 pieces per experimental unit) were reared for 45 days under standard conditions. Experimental groups included a control treatment (no beets) and nutritional treatments with 5%, 10% and 15% were beets. For measuring changes in skin color on the 45th day in Experiment, 2 pieces of fish from each replicate were randomly selected and slaughtered. After a side cut on the part of the body with the skin and also making cold for 24 hours, based on three criteria colorimetric parameters L * (brightness), a * (redness) and b * (yellowness) colorimetric device 400-MINOLTA CR were evaluated. Results were shown significant differences between experimental groups, there were no effects on the skin and flesh color (05/0 <P). Although numerically the highest rates of red meat and skin index was for 10% beet group and the highest value of yellow and brightness index was for no beets group. Although by calculation ΔE (the deviation of color) in the skin, the results were shown that 10% beet group had more significant differences than the other groups (P <0/05). And also there was a significant difference (P <0/05) in the flesh which was in P-value level (probability level)

Funnel plot is a graphical tool for investigating publication bias in meta-analysis studies. The aim of this study is to introduce another application of funnel plot that is monitoring one of the Iranian family performance indices and determining the position of each health center of Markazi province in terms of patient referral rates by general practitioners to specialists and to compare it with bar and caterpillar plots. In order to draw the funnel plot، the average monthly percent of referrals for each district of Markazi province in 2011 was computed. In this study، Iranian Ministry of Health and Medical Education standard figure of 10% was considered as the limit of referral to the second level of Iranian health services. The 99% confidence interval of the control limit for each district was computed according to 3 standard deviations of the percent of referrals relative to the total patient visits. Based on funnel plot results، five out of ten districts were in the expected range of referral (Ashtian، Saveh، Tafresh، Khomein، and Komijan). However، in other five districts، the referral rate was greater than the expected rate (Arak، Shazand، Zarandiyeh، Delijan، and Mahallat). Mahallat district had the highest rate of referral. The funnel plot was more informative than the other two plots; thus، it can be viewed as a useful tool in monitoring health programs throughout the country.

Now days, Medias are one of the most important instruments for expanding and transforming social and also cultural values on children and youth's behaviors. This study investigates the affects of Medias on children and youth's behaviors in Community. Thus, samples are selected among parents and children in Kerman city and tested by researcher questionnaire. Data analyzed and result indicated that there is significant correlation between uses of Medias and social and cognitive development. Also, according to this research, there is not significant correlation between uses of Medias and emotional and psychological development.
