Technological features of powdered reagents injection into the melt using a submersible tuyere were investigated for research and development main provisions rail steel out–of-furnace treatment in ladle-furnace. Authors analyzed characteristics influence directed heat flow through conditional separation wall from metal to two-phase gas-powder under purging conditions. Using numerical methods, w...

In this work, we present and characterize a microwave plasma microtorch that can support the formation of diamond nanoparticles (DNPs) in gas phase when using hydrogen-methane as precursor gas. We first showed how nonequilibrium character obtained ensures enhanced H-atom, C 2 ${{\rm{C}}}_{2}$ , CH 3 ${\text{CH}}_{3}$ production at moderate temperature levels provides thermal stability DNPs. The...

Magnesium materials are of increasing interest in the development of biodegradable implants as they exhibit properties that make them promising candidates. However, the formation of gas cavities after implantation of magnesium alloys has been widely reported in the literature. The composition of the gas and the concentration of its components in these cavities are not known as only a few studie...

In this study, fertilization, hatching and deformation rate of the eggs, and larvae obtained from hormone injected (HI) and non-injected broodstock (NHI), were determined. In the experiment, no differences were observed in the groups’ fertilization rates (p>0.05). Hatching rate was found higher in the HI group (p < 0.05). During the experiment, malformations such as spinal fluid accumulation, s...

PURPOSE To test the antiviral effect of ganciclovir released from biodegradable polymer microspheres in rabbit eyes inoculated with human cytomegalovirus (HCMV). METHODS Human cytomegalovirus (5 x 10(3) plaque forming unit in 0.1 ml Hank's balanced salt solution) was inoculated 4 days after gas compression vitrectomy. Injected after 2 days was 10 mg of 300- to 500-micron ganciclovir-loaded mi...

The experimental study and modeling of gravity drainage during Water Alternative Gas Injection, WAG process, in carbonate rock for one of the Iranian off-shore reservoir at lab-scale were carried out. The mechanism of gravity drainage during the WAG process, and its contribution to the oil recovery in the fract...
