One of the simple methods for erosion control, flood mitigation and flood damage reduction in the streams is building the check-dams. The present study was carried out to evaluate the performance of check-dams, location across the streams in the retention of the fine sediments in Dam-tang watershed in Darab Iran. For this purpose, two of streams with many stabilized check-dams which were more t...
Background & Aims : Cancer cells proliferation may be mediated by abnormal phosphorylation of signaling pathways downstream of tyrosine kinase receptors such as Platelet derived growth factor receptor α (PDGFR-α) and β (PDGFR-β). We aimed to study the phosphorylation level of PDGFR-α and PDGFR-β and apoptosis in mouse normal leydig cells being exposed to Imatinib. Materials & Methods : The ...
The technique used to control the airflow is based on the electro-hydrodynamic actuator which is also called plasma actuator. This actuator ensures the airflow control thanks to the electric wind created by the electrical corona discharge. This ionic wind is developed at the profile surface tangential to the initial free airflow so that it has a significant effect on the boundary layer flow. Th...
In this paper airflow, nano-and micro-particle motions in an aerodynamic particle beam focusing system consisting of several lenses, a nozzle and the downstream chamber, was studied. A three-dimensional numerical simulation for the system was presented and the compressible airflow and thermal conditions in the aerodynamic lens system were evaluated. Dilute particle concentration was assumed so ...
One of the unique characteristics of cellular signaling pathways is that a common signaling pathway can selectively regulate multiple cellular functions of a hormone; however, this selective downstream control through a common signaling pathway is poorly understood. Here we show that the insulin-dependent AKT pathway uses temporal patterns multiplexing for selective regulation of downstream mol...
