Limitations on water resources and the high costs of new hydraulic structure construction intensify the need for an optimum operation of Iranian reservoir systems. For appropriate water distribution and management in a 9-reservoir system on the Kalamarz river, Mianeh basin optimizing mathematical models are applied. Considering the stochastic nature of river discharges and the constant amount o...

sunn pest is considered as the most important insect pest of wheat and barley in iran. different studies have shown that various biotic and abiotic factors affect sunn pest populations. these factors can influence the population density of the pest which in turn can play a role in the control of the pest. in this study the relationship between sunn pest population fluctuations and climatic cond...

isotopic and microthermometry results from sheikh-darabad cu-au indices in mianeh region, east-azarbaijan province, indicate cenozoic post-magmatic activities with developed adularia facies through an extended and neogene related alteration that is given rise to occurring silica vein systems as the main hosting locations for epithermal mineralization. the research evidence also has been coincid...

Using IEC 61850 standard would increase the reliability and availability of electricity network and put a huge impact on network automation. Even though much research works has been done in substation system reliability, there is a few works in automated substation control system reliability. This paper evaluates the reliability of substation automation system based IEC 61850 comparatively cons...

Introduction: The aim of this study was to characterize the chemical composition and antimicrobial activity of Trachyspermum copticum essential oil (EO). Methods: The chemical composition of seed samples obtained from Mianeh city in East Azerbaijan, was assessed using gas chromatography-mass spectrometry (GC-MS). The antimicrobial activity was evaluated by disc diffusion method against methicil...

Dam spillways are the structures that lead rightly and safely the outflow downstream, so that the dam integrity can be guaranteed. Many accidents with dams have been caused by an inadequate spillway design or insufficient capacity. To accurately respond the hydraulic spillways, designers use physical modeling for designing this kind of structures. The scale effect in the spillway modeling, as a...

Background and Objectives: One of the key issues in determining location for blood supply center is the design of blood supply chain. To minimize the cost of blood supply, the donors should be reached easily with appropriate distribution of blood and blood products to the hospital. The aim of this study was calculating of the optimal number and location of different various t...
