با افزایش تعداد سویه های باکتریایی مقاوم به آنتی بیوتیک های مختلف و قیمت بالای برخی آنتی بیوتیک ها نیاز به داروهای گیاهی موثر، در دسترس و ارزان احساس می شود. این مطالعه به منظور مقایسه اثرضدباکتریایی عصاره های قطبی و غیر قطبی دوره های مختلف رویشی گیاه اسپند (peganum harmala) بر روی باکتری های آئروموناس هیدروفیلا (aeromonas hydrophila)، فتوباکتریوم دامسلا (photobacterium damsela) و لاکتوکوکوس گا...
it was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (ap). it seems that some other types of mechanisms must be involved in ap propagation. in this article, we...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Background: The variation of the radon progeny concentration in outdoor environment and meteorological parameters at fine resolution were studied for one year at a continental location, National Atmospheric Research Laboratory, Gadanki, India. Materials and Methods: The concentrations were measured using Alpha Progeny Meter by collecting air samples at a height of 1 m above the Earth&rsqu...
