Nesfatin-1 and Apelin as two inflammatory adipocytokines affected by various stresses, including exercise. The purpose of this study was to investigate the effect of 14 days of resveratrol supplementation on changes in serum levels of Apelin and nesfatin-1 in response to one bout of exhaustive exercise in young sedentary overweight men.

20 young sedentary overweight men (mean aged= 35.7±3.26 years, BMI= 28.73±1.18 kg/m2) selected and randomly divided into two groups (experimental and control). Subjects in both experimental and control groups participated in one bout of exhaustive exercise (Bruce Test). Then, subjects in experimental group (supplementation) consumed one capsule of 400-mg resveratrol per day for 14 days. In control group (placebo), subject consumed one capsule of 400-mg lactose per day for 14 days. First blood sample was taken before the study and second one was done immediately after Bruce test. At the fifteenth day and at the end of 14 days of supplementation, subjects in both groups perform the exhaustive exercise again and forth blood sample was taken immediately following their performance. According to t-test, in the experimental group and following supplementation, changes in serum levels of Nesfatin-1 were significant in response to one bout of exhaustive exercise. However, following supplementation, there were significant differences between mean changes of Apelin levels in response to one bout of exhaustive exercise in experimental group compared to control group. According to Pearson correlation, there existed significant correlations between primary levels of Nesfatin-1 and primary values of body weight.

The most important part to be considered is the determination of the carrying capacity of the protected areas, since these areas are able to accommodate a large number of tourists, so if these areas are not planned more accurately, the number of tourists will exceed the cc limit of the area. Resulting in instability and degradation of these areas, and therefore knowledge of the status of the area's cc will greatly help to control the damage. The aim of this study was determine potential, and social-cultural cc with the purpose of the establishment in ecotourism development. Therefore, in order to the determination of the potential of this area, calculation of the social-cultural cc after the identification of the social - cultural pressures using model PSR the social- cultural pressures regarding the calculation of the correction by applying the percentage corrections of the pressures and the relative importance using the techniques ANP and of each of them after the grading layer using the techniques WLC and builder model at Arc GIS10.5 combined. Social - cultural cc in the direction of the development of ecotourism determined. The results 50% of the content that the level region has high cc, 33% of the surface area has an cc and 17 percent of the level region has low cc. Findings of the research show that there is a low range of cc in the central part of the region; finally, based on the findings, suggestions have been made to increase the regional distribution cc.

Reinforced concrete shear walls have a high out-of-plane stiffness, while the steel shear walls have a slight out-of-plane stiffness. To prevent the buckling, the steel plates are connected to the concrete panel by shear lugs (composite shear walls). In this paper, the behavior of coupled composite shear walls is investigated. The results show that the stresses created in the system of coupled shear walls are reduced in comparison to separate shear walls and that lateral stiffness is increased. However, increasing rigidity of coupled beams more than a specified amount does not significantly affect the elastic behavior of the system. Therefore, a relation that can approximate the the ideal coupled beam is suggested. A dual system of steel moment-resisting frame and composite shear walls was designed, and static nonlinear analysis was performed. In the following, the composite shear walls are assumed to be unchanged, and the dimensions of the coupled beam are calculated by the proposed relationship and static nonlinear analysis has been performed. Comparison of the results shows that the resistance and seismic parameters of the coupled shear walls are more than separate shear walls. The studies show that increasing the rigidity of the coupled beams more than that of the ideal beams does not have a significant effect on the increase of the resistance parameters of the system and, moreover, the ductility of the system decreases. Therefore, the dimensions of the ideal coupled beam cross section are predicted well even in the nonlinear performance of the system.

Tourism is a large industry and one of the most dynamic sectors of the economy of every country. Today, tourism also provides an efficient tool to governments for introducing culture of the destinations to other nations. In this study, we identified criteria for tourism and then normalized and prioritized those criteria using PROMETHEE, AHP and ANP methods in Expert Choice and Super Decision software. Each one of the methods provided different ranking based on the nature of their approach. We generated maps of the criteria and overlaid them in GIS for tourism capability assessment. Results of this study indicated that the PROMETHEE method ranked slope as the first, elevation as the second and aspect as the third criterion. The AHP weighting method ranked slope as the first and vegetation density as the second factor, while the ANP ranked slope as the first, vegetation density as the second and aspect as the third. For extensive tourism, 98% of the area has very high capability and 2 % has high capability. For intensive tourism, 62 % of the area has very high capability, 37 % has high capability and the rest 1% has no capability. Our results indicate the high capability of the area for tourism and its potential can best be realized through appropriate planning.

Noise pollution can exert negative effects on mental health. In this regard, the present study aimed to evaluate the noise levels in sugar factory of Debal Khozaei agro-industry complex in 2018.

For the current study, sound and audio parameters were measured using a sound meter. These audio parameters included sound pressure level and minimum and maximum values measured in 9 units located in the interior space of the factory entailing 38 study stations  with 30 points in open space. It is worthy to note that sound measurements were performed twice a week in morning and afternoon shifts at time intervals of 15 min. Data were analyzed in SPSS software (version 16) using the ANOVA test.

Based on the results, the maximum and minimum sound pressure levels of power plants and white sugar warehouse were 0.86 ± 91.10 and 0.44 ± 91.10 dB, respectively. Additionally, the comparison of the average sound pressure level at different stations in the power plant and raw sugar production units, as well as some stations in the sugar refinery, lime kiln, and boiler exceeded the standard limit of 85 dB. However, this value was found to be below standard in the open space of the factory.

The ongoing monitoring along with the application of noise reduction techniques is recommended due to the excessive noise levels in some parts of the factory.

With the development of technology, and the diversification of chemicals needed in the industry, agriculture has increasingly expanded in recent decades, with increasing population, industrial and agricultural activities; the input of pollutants into the environment has increased. This research was carried out in 2016 with the aim of evaluating the possibility of non-cancerous effects of heavy metals caused by the consumption of Barbus grypus fish in the city of Mahshahr in summer. In this research, samples of fish required from the daily fisherman's hunting in Mahshahr port were prepared in 2016. Sampling was done randomly from trapped and ready-made fish in the market, in which 26 samples were used. After biometrics, the muscle tissue of the samples was isolated and chemically digested. A ratio of density of cadmium, nickel, lead, chromium and zinc on the muscle was measured by atomic absorption device (Ultima2c) and based on information gathering; the risk ratio of heavy metals was determined by the questionnaire. The results of this study showed that the average concentration of cadmium and nickel, lead, chromium and zinc on fish Barbus grypus to arrange 2. 848, 1. 933, 23. 3, 23. 93 and 0. 045 mg. dry weight, which was the amount of metallic cadmium, nickel, lead higher than the standard set by the world Organization like FAO, WHO, MAFF and FDA. According to the results of this study, the hazard ratio (HQ) of cadmium was higher than 1 (1. 10), nickel lower than 1 (0. 82), lead more than 1 (999. 9), chromium less than 1 (0. 019), and zinc more than 1 (10. 25), according to which the consumption of Barbus grypus fish in this area would have a severe risk for consumers as a result of heavy metals.

Heavy metals enter the environment by natural and human resources, and the rate of their entry into the environment is considerable. Water ecosystems are naturally the final recipient of the metals. This study aimed to determine the bioaccumulation of heavy metals (Cd, Cr, Ni, Zn, and Pb) in, Cyprinus carpio fish. The concentrations of heavy metals were measured using atomic absorption spectrophotometer method. Samples of C. carpio muscle in Dezful City, southern Iran were assessed. Overall, 200 C. carpio fish samples were selected and analyzed randomly. The mean concentrations of Cd, Cr, Ni, Zn and Pb were respectively 2.08, 0.2, 1.41, 39.95, 34.5 mg/ kg dry weight. The amount of Cd, Ni, Pb was higher than standard level of the FAO, MAFF, FDA, and WHO but Cr and Zn was lower than the standard of international organizations. Risk index (HQ) of Cd and Pb metals was higher than one but for other metals were lower than one. Consuming this kind of fish is a serious threat for consumers of the region.

Introduction and aims of research: 

With the increase of population in the cities and consequently growth of student population, Construction and the revival of learning spaces as one of the original user should consider. Therefore, the importance of a comprehensive review on how the distribution and development of teaching spaces and a realization that over flexibility is essential. This study examines the assessment of educational spaces, switching locations using GIS and AHP elementary.

In this study, primary schools for girls and boys of Karun city with the neighboring matrix (semi compatible, incompatible, quite compatible, incompatible), Capacity (per capita infrastructure, outdoor, roofed, the density of students in the class, the frequency of use of the educational units, the status property of the schools, the status of the useful life of the building, the status of the structure type of the building of schools) and compliance is evaluated.

The results have shown that the assessment of educational spaces studied, Much of the conflict with the user around, the lack of schools in some localities due to the population, the need for the required user. It is also used in building materials for schools due to the great performance of dating are not entitled to.

Therefore, the creation of optimal location planning for future site for educational centers and check solutions for identification of some limitation on the scope of the deficit and a case study is essential.

Application of a substrate integrated waveguide with wiggly ridge shape is presented for excitation longitudinal shunt slot antenna. Two main design equations for design substrate integrated waveguide structure and get parameters of structures، for longitudinal shunt slot excitation by shape wiggly ridge in substrate integrated waveguide are modified. Proposed method is used by applied the crinkle shape to ridge for ridge substrate integrated waveguide structure. This shape wiggly ridge just under longitudinal slot. The slot is place at centreline of substrate integrated waveguide (siw) in center of waveguide and on dielectric copper surface، top of substrate integrated waveguide. Amount of crinkle depth of waveguide centreline is proportional with needful radiation of slot and normalized conductance could be much to increase crinkle depth. In this paper the shunt element distribution assumption for prposed structure is spoted. Results of simulation show، proposed method is suitable candidate for replacing with usual longitudinal shunt slot. Structure’s useful is، low fabrication price، small profile and adaptation with microstrip circuit. Also slot place along waveguide centerline and wiggle depth substitute slot offset، therefore this procedure can suppress second order bim in array containing suggestion structure.
