Statistical experimental design was used to optimize the conditions viz. Ethanol, Ammonium phosphate and Biotin concentration of L-Glutamic acid from Brevibacterium roseum NCIM 2238 by submerged fermentation. Maximum L-Glutamic acid concentration of 53.01621 g/l was obtained. The optimum conditions were found to be ethanol concentration of 5.3646 %v/v, ammonium phosphate of 0.7081 %w/v and biot...

This paper presents a new application of the normal mode decomposition to measure the reflection and absorption coefficients of a low growing living plant in a large 300 300 mm impedance tube. In this way the higher frequency limit can be extended by a factor of 3 in comparison to that suggested by the standard ISO 10534-2 method for this type of an impedance tube. The adopted method (Prisutova...

Ag thin films were successfully produced via a green chemistry method from silver nanoparticles (AgNPs) obtained reacting an extract of Pelargonium Zonale leaves with nitrate. The ions nitrate reduced to atoms by reducing stabilizer-capping compounds contained in the leaves. nucleate small clusters that grew into and finally, they formed homogeneous film on glass substrate. nanostructured chara...
