‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Melanin: A Solution for Photoprotection of Bacillus thuringiensis Based Biopesticides

Melanins can be obtained by chemical and microbiological synthesis, or by extraction from animal and plant tissues. One of the major problems in studying melanins, is the lack of adequate methods for the isolation of pure melanin pigments. Remarkably, little is known about the structures of melanins, despite their abundance in the global biomass. This is due to the inability of current biochemi...

larvicical activity of bacillus thuringiensis h-14 (teknar) on mosquito larvae in ricefields, southern iran

an investigation was conducted to study the larvicidal activity of teknar (san-402-i-bacillus thuringiensis, serotype h-14, sandoz, 600 itu/mg) on mosquitolarvaein kazeroun, fars province, southern iran. five experimental plots were selected randomly in a rice field and three concentrations of teknar: .0003, .0006 and .0012 cc/1 was used. maximum larval mortality usually occurred during the fir...
