Taking into account modulatory effects and intermediary effects together, this study provides a more comprehensive understanding of the relationship between entrepreneurial orientation and performance, which highlights the mediating role of marketing capability and the moderating role of marketing resources. For this purpose, data were collected from 71 companies located in the science and technology park of East Azarbaijan province through a questionnaire. The results of statistical data and structural equation modeling using SPSS and SmartPLS software showed that entrepreneurial orientation both directly and indirectly and through marketing ability affects company performance. Also, the results showed that the variable of marketing resources in the indirect relationship of entrepreneurial orientation and firm performance through marketing capability has a moderating role in the way that the indirect impact of entrepreneurial orientation through marketing capability on the company's performance in high amounts of moderation (marketing resources) Is stronger than its indirect effect in low amounts of moderation (marketing resources). Based on the results of this research, companies can achieve superior performance by targeting entrepreneurial activities by choosing the right strategy and adopting some of their resources to marketing resources

Sarein hot mineral springs have a great important role in supplying water resources, economical development and attraction of tourists in the area. Therefore, the study of qualitative and quantitative changes trend of water has a great importance. In this study, non-parametric Mann-Kendall test was used to evaluate the qualitative and quantitative parameters of Sarein mineral hot springs (9 springs) during 1981–2011 at 3 significant levels of 1%, 5% and 10%. The quantitative parameters are discharge and temperature With 25 years of monthly data and qualitative parameters are pH, silica content, electrical conductivity and total hardness With 30 years of annual data. Firstly, the first order significant autocorrelation was removed from the data set. For each data series, the slope of the trend line was calculated using Sen Gr estimators. At last, a relatively acceptable general consistent with the basic premise of the research on reducing the discharge and temperature rise due to global warming were obtained. Most of the springs discharge had a significant negative trend and on the other hand, the trend of Springs is a reducing trend. The results for the temperature of the springs showed that 3 spring's temperature was increased and 2 Springs temperature was reduced and other springs have no significant trends. pH and silica levels in most springs has increased during 30 years ago and Electrical conductivity and total hardness was reduced in most of them.

Instantaneous unit hydrograph (IUH) is a hydrograph that has used for calculation of direct runoff hydrograph in watersheds and recent addition to formal methods, Shannon entropy theory consider for calculation of direct runoff hydrograph. If the system disorderly is measured in terms of entropy then the probability distribution of the events, provides in terms of entropy. In this theory, defined travel time as a random variable, the maximizing the entropy on based this parameter and also specifies constraints, the least-biased probability density function, determining parameters of the IUH and finally obtaining applicable IUH equation. In this study, six events of Lighvan watershed has been studied that located in Northwest Iran. After calculating travel time and determining parameters on based entropy, derivation applicable IUH equation and calculated direct runoff hydrograph. For estimated and more evaluated IUH and direct runoff hydrograph has used Gamma distribution that result showed good accuracy of the entropy theory. The results indicate acceptable performance of the entropy model shows the average correlation coefficient (0.828), mean error of peak (17.35%), entropy index (2.47 knot) and nash-sutcliff value (NS=0.742) in verification events.
