during a survey on the identification of plant-parasitic nematodes associated with walnut in sanandej region (kurdistan province, western iran), a population of paratylenchus labiosus was collected and identified morphologically. description, illustrations and morphometrics of the species are given and comparisons are made between it and some related species. paratylenchus labiosus comes more c...

This study investigates impacts of oxygen flow during the deposition of amorphous indium–gallium–zinc oxide (a-IGZO) channel layer with a radio frequency (r.f.) magnetron sputter on the electrical characteristics of the fabricated thin-film transistors (TFTs). Results indicate that as the film was deposited with a higher oxygen flow, the transfer curves are positively shifted while the field-ef...

We have embedded a physically defined p-channel silicon MOS quantum dot (QD) device into an impedance transformer RC circuit. To decrease the parasitic capacitance and surpass cutoff frequency of which emerges in devices that top gate act as low-pass filter, we fabricate new to reduce device's area from 400 $\mbox{$\mu$m}^2$ 0.09 $\mbox{$\mu$m}^2$. Having smaller eliminates problem preventing R...

zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

A 15-year retrospective study was performed to determine the role of parasitic diseases in causing mortalities in small ruminants. In total, 115 (32 %) sheep were diagnosed as having been killed by parasitic diseases out of 366 that died as a result of disease. The major cause of mortality was helminthosis (63 % of all parasitic cases). Most of the helminthosis cases were attributed to haemonch...
