NMDA (N-methyl-D-aspartate) receptors and calcium can exert multiple and very divergent effects within neuronal cells, thereby impacting opposing occurrences such as synaptic plasticity and neuronal degeneration. The neuronal Ca2+ sensor Caldendrin is a postsynaptic density component with high similarity to calmodulin. Jacob, a recently identified Caldendrin binding partner, is a novel protein ...

Impeller trimming is a proper way to alter the performance of centrifugal pump with a constant speed so as to meet the demand on the specified flow rate and head in pumping systems. The affinity law accounting for the impeller trimming is the key relation to determine the pump performance with a trimmed impeller. There seems no experimental study dealing with such an affinity law for centrifuga...

Mussel control in cooling water systems is generally achieved by means of chlorination. Chlorine is applied continuously or intermittently, depending on cost and discharge criteria. In this paper, we examined whether mussels will be able to survive intermittent chlorination because of their ability to close their valves during periods of chlorination. Experiments were carried out using three co...

Design and construct ion of a stable current supply with protect ion circu its are Abstract described. The reported circuit provides a high-stable and high-level current variable from 0.5 -1.2 A with the prot ect ion circu its to prevent over load cur ren t , voltage and off-range temperature operat ion. A detailed analysis of the circu it parameters is given and the time behaviors of the load ...

soil erosion is a serious problem especially in northern parts of iran. one themost important side effects on soil erosion may be the decline in qualities of soil refers toagricultural productivity. so it is very important to assess the soil erosion risk for thesustainable development of agriculture. this study outlines ways undertaken to provide anew tool to manage water erosion from physical ...

To support farming year-round, a variety of smart IoT irrigation devices have recently been developed. It is crucial to forecast the soil moisture agricultural farms so as produce high yields since depends on efficiency water supply farmlands. In irrigation, anytime needed farms, pumps switch pump required prevent crops from drying up. The also shut down if ideal level moisture, preventing over...
