In this paper, kinetics of DC electrophoretic deposition EPD of carbon nanotubes CNTs is investigated. Carbon nanotubes suspended in pure ethanol with addition of magnesium nitrate was used as deposition media. The effect of main EPD parameters such as deposition time, applied voltage and the CNT concentration on deposit yield was investigated. The variation of current density vs. time and the ...

carbohydrate flow between vegetative and reproductive parts of trees is one of the determining factors of yield and fruit quality. therefore, it varies during different times of growth season. the aim of this study was to investigate the carbohydrate content variation during growth season between leaf and fruit of nectarine. so, eight nectarine trees cv. red gold selected randomly in the orchar...

kahman is the most beneficial river in alashtar city for agriculture and aquiculture. as hydrology processes have random nature, statistics and probability are base of analysis of these processes and time series are used for this purpose. the first step in time series analysis includes parameters variation through time. second step is to stationary data, third is normalization and forth is mode...

Considerable attention has recently been devoted to the linear trend of drought at the decadal to inter-decadal time scale; however, the nonlinear variation of drought at multi-decadal scales and its relation to atmospheric circulation need to be further studied. The linear and nonlinear variations of the Palmer drought severity index (PDSI) in Shandong from 1900 to 2012 and its relations to th...
