any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
In this study, Aluminium nanoparticles were synthesized by arc discharge method applying direct current between aluminium electrodes in liquid medium without the need to vacuum equipment, heat exchangers, furnaces and inert gases. In situ coating process was applied to the nanoparticles. Sample analysis indicates that the particle size was less than 30 nm. In this study, it has been seen that t...
lysine is nutritionally essential for humans and animals. it cannot be synthesized biologically in body. children and growing animals have a high requirement of lysine, since it is needed for bone formation. therefore, it must be added to food and feed supplement to improve the protein quality. in addition, lysine has some pharmaceutical applications in the formulation of diets with balanced am...
The aim of the present study was to isolate cyanobacteria from oil refinery waste water and detection of antagonistic activity of their extracts on four species of pathogenic bacteria. The cyanobacterium was isolated and purified on Blue green algae medium number 11 (BG-11) medium. Methanol and water extracts prepared from the cultured cyanobacterium after 45 days growth on BG-11 medium. The bi...
The growth of microorganisms in a synthetic medium is influenced by a number of physical and chemical factors. The nutrient composition of a culture medium plays a most important role in microbial growth (Tortora and Funk, 1995). Fungi grow on diverse habitats in nature and are cosmopolitan in distribution requiring several specific elements for growth and reproduction (Singh and Sharma, 2014)....
The mutant strain Trichoderma reesei WX-112 with high cellulase activity was isolated by a newly invented plate. The mutant’s ability to produce cellulase increased 1.95 times after the treatment with UV and N-methyl-N’-nitro-N-nitrosoguanidine (MNNG). Also, the medium composition was optimized using response surface methodology (RSM). A fractional factorial design (2) was applied to elucidate ...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
The nutritive value of Ceratonia siliqua and Gleditsia triacanthos pods was determined on the basis of their chemical composition, in vitro gas production and rumen fermentation end-products. Medicago sativa was used as a reference feed material. The studied samples showed differences in chemical composition and phenolic compounds. Crude protein (CP) content was particulary low (80 g/kg DM) in ...
