Background With considering the importance of natural products for their remedial and therapeutic value, this research was aimed to analyze the chemical compositions and antimicrobial activity of four propolis samples from different areas of Iran (Chenaran, Taleghan, Morad Beyg, and Kalaleh) with various climates and flora. Methods Ethanolic (70% EtOH) and dichlromethane (DCM) extracts of Ira...

The present study was carried out to determine the possible origins of sediments entering Taleghan Dam in northern part of Iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. This was performed by XRD analysis. To do so, first of all, sediment sampling points were positioned along the Taleghan River. The collected samples, after coding,...

  Substantial population growth and urbanization arbitrarily banning the exploitation of natural resources and environmental factors adversely impacts the environment and resources necessary for nutrition and healthy life styles. The secret to success and survival of ecosystems depends on a stable, continuous monitoring of the environment. The SWOT model has been developedto consider all int...

Due to the immense damage caused by dam failure, especially dams constructed near large cities, it is necessary to consider the breaking phenomena as well as studying and designing different parts of the dam. For this purpose, the hydrograph of the outflow due to dam failure must be identified according to size of the fracture and then flood routing, and flood zone must be determined based on t...
