Electroporation is one of the most widely used transfection methods because of its high efficiency and convenience among the various transfection methods. Previous micro-electroporation systems have some drawbacks such as limitations in height and design, time-consuming and an expensive fabrication process due to technical constraints. This study fabricates a three dimensional microelectrode us...

the effect of poultry waste application on physicochemical and biological properties of sandy clay loam soil was investigated on a 7m x 7m plot of land. plot was divided into four portions and 7.5kg each of broiler, cockerel and layers waste was applied to plot a, b, and c in slurry form while plot d was used as control(no application) for eight weeks with two weeks interval. after the fourth a...
annually, 200 ha of agh ghala rangelands in golestan, iran are under alkaligrass puccinella distans's cultivation but the failure in the identification of appropriate sites for seed sowing may result in high costs of cultivation. the current study aims to reduce such costs through the examination of apt sites to grow p. distans in northern rangelands of agh ghala golestan, iran. because of the ...
