This study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in Iran. To this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. The main factor included different levels of silicon (0, 10, 20, 30 mM.l-1) ...

Carbon nanotubes (CNTs) were deposited on various substrates namely untreated silicon and quartz, Fe-deposited silicon and quartz, HF-treated silicon, silicon nitride-deposited silicon, copper foil, and stainless steel mesh using thermal chemical vapor deposition technique. The optimum parameters for the growth and the microstructure of the synthesized CNTs on these substrates are described. Th...

Solid silicon monoxide is an amorphous material which has been commercialized for many functional applications. However, the amorphous structure of silicon monoxide is a long-standing question because of the uncommon valence state of silicon in the oxide. It has been deduced that amorphous silicon monoxide undergoes an unusual disproportionation by forming silicon- and silicon-dioxide-like regi...

Due to the nature of their deployment, very few people know location and course a submarine during its time at sea, including only handful ship’s crew. The possibility immediate retaliation by UK her allies is aided submarine’s ability remain undetected SONAR all times. To investigate one method for improving acoustic stealth, finite element model (FEM) was created on ANSYS unit-cell an Alberic...

Neutral beam injection (NBI) systems based on negative hydrogen ion sources—rather than the positive sources that have typically been used to date—will be in future magnetically confined nuclear fusion experiments heat plasma. The collisions between fast ions and neutral background gas result a significant number of high-energy being produced acceleration area, for high-power long-pulse operati...

Silicon nanowire (SiNW) arrays were produced by electroless method on polycrystalline Si substrate, in HF/ AgNO3 solution. Although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. In order to study the influence of etching time (which affects the SiNWs length) on d...

In this study, some metals (aluminium, chromium, copper, iron, manganese, lead, zinc and vanadium) and metalloid (silicon) were determined in water, sediment and some tissues of fish Cyprinus carpio from Mogan Lake. Fish samples were caught in March 2007. As a result of the examination of metals in the water aluminium has the lowest and silicon has the highest concentration. In sediment samples...
