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...
resistance to drug such as metronidazole is one the commonest causes of treatment failure while eradicating helicobacter pylori . considering the safety of ketoconazole and fluconazole and their inhibitory activity on biosynthesis of fatty acids from cholesterol in cell membrane of h.pylori , the idea of their efficacy against h.pylori is raising . the aim of this study is to evaluate susceptib...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Antibiotics are the best known products of actinomycete. Over 5,000 antibiotics have been identified from the cultures of Gram positive and Gram-negative organisms, and filamentous fungi, but only about 100 antibiotics have commercially been used to treat human, animal and plant diseases. The genus, Streptomycete, is responsible for the formation of more than 60% of known antibiotics. Bacteri...

abstract- lactic acid bacteria are commonly found in the gastrointestinal tract of various endothermic animals and humans, in milk, dairy and seafood products and on some plant surfaces. the aim of this study was to investigate the inhibitory effect of isolated lactic acid bacteria from intestines of narrow-barred spanish mackerel (scomberomorus commerson) on listeria innocua growth. five strai...
Although recent studies have suggested that some antibacterial agents have good activity against the rapidly growing mycobacteria Mycobacterium fortuitum and Mycobacterium chelonei, an easily applicable method for susceptibility testing of clinical isolates is not yet available. We evaluated a disk diffusion method with Mueller-Hinton agar and 48-h readings with 59 strains of M. fortuitum and 1...
Background: Acinetobacter baumannii is an opportunistic pathogen and a nosocomial infection agent. Antibiotic resistance in this organism results in serious health problem such as treatment failure and increased mortality. Mangrove plants, especially Avicennia marina, are a potential bioresource for new drugs as they have been used in traditional medicine. This study aimed to investigate antib...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Streptococcus is the leading cause of dental diseases worldwide and is considered to be the most cariogenic of all of the oral bacteria. The total 150 dental plaque sample were collected from Uttranchal dental college and hospital dehradun and different dental clinics of dehradun. Out of 320 isolates recovered prevalence of Streptococcus sp. was 50%. 10 antibiotics were used against the recover...
