abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Abstract Lithium-ion capacitors are envisaged as promising energy-storage devices to simultaneously achieve a large energy density and high-power output at quick charge discharge rates. However, the mismatched kinetics between capacitive cathodes faradaic anodes still hinder their practical application for purposes. To tackle this problem, electron ion transport of both electrodes should be sub...
1- in a search directed to the reaction of compound)23(the cycloaddition reaction of 1,3- diphenylisobenzofurane)14(with p-benzoquinone)19(,followed by addition of cyclopentadiene was carried out.the specific spacial stracture of its ir,nmr,mass spectra. 2- in another attempt the kinetic stability and behavior of compounds)20(and)23(was studied.the main subject of this study was the highly reve...
ABSTRACT Biomass as raw material is one solution that can be developed in the management of agricultural, plantation, and industrial waste. The utilization biomass-derived from waste help reduce pollution environmental pollution. This research was conducted to make Silicon Carbide (SiC) adsorbent wood biomass using Sengon sawdust a source carbon non-wood biomass, namely coconut husk, silica. Si...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
این تکنیک طی 20 سال گذشته در درمان شکستگی های رایج فک و صورت مورد استفاده بوده است . زیرا عفونت کمتری را داراست . این تکنیک مخصوصا" برای بیماران فاقد همکاری، بیمارانی که نیاز به تحرک سریع فک دارند و یا نیاز سریع برای دسترسی به حفره دهان دارند(بیماران icu )، بیماران با نیازهای تغذیه ای خاص از جمله افراد دیابتی و الکلیک ، افرادی که شکستگی عفونی داشته و نیاز به open reduction دارند، افراد دچار بیم...
many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...
