The present studies were conducted to isolate, select, identify and characterize gut bacteria as antimicrobial and growth promoting agent for the feed of economically important fish Cirrhinus mrigala. Intestinal microflora were isolated, counted, and identified, and their in vitro antibacterial properties were determined. The results have revealed that occurrence of Gram-negative rods was around 75% and of Gram-positive rods was 25%. Among the isolates Gram-positive were maintained in nutrient agar slants at 4℃. Of these, eight strains were replica-plated on agar seeded with Aeromonas hydrophila and only one strain CM2（C. mrigala 2） exhibited antibacterial properties in vitro showing inhibition against fish pathogen by well diffusion assay. This isolated strain was identified as Bacillus cereus. This bacterium was mass cultured and incorporated in the pelleted diet（40% protein and 18 k J g^–1 gross energy） of C. mrigala to investigate its effect on growth performance, digestibility, nutrient retention and activities of digestive enzymes. The results of feeding trial revealed significantly（P〈0.05） high growth performance in terms of specific growth rate, growth percent gain in body weight（BD）（272.4±1.5）%, high apparent protein digestibility（（79.9±0.30）%） and low food conversion ratio in the group of fishes fed on diet containing B. cereus in comparison to the fishes fed on diet without probiotics. The carcass composition also revealed high accumulation of proteins（（15.28±0.15） g 100 g^–1） in fishes fed on diet containing probiotics. Intestinal enzyme activities of protease, amylase and cellulase were also significantly（P〈0.05） high in the group of fishes fed on diet supplemented with probiotics indicating the extracellular enzyme production by B. cereus. These results indicate that probiotics stimulate the digestion through the supply of digestive enzyme and certain essential nutrients to animals. Also significantly（P〈0.05） low excretion of metabolites, i.e., ammonia

The three-dimensional inverse transient thermoelastic problem for a thin rectangular object is considered within the context of the theory of generalized thermoelasticity. The upper surface of the rectangular object occupying the space D: a≤x≤a; b≤y≤b; 0≤z≤h; with the known boundary conditions. Laplace and Finite Marchi-Fasulo transform techniques are used to determine the unknown temperature, temperature distribution, displacement and thermal stresses on upper plane surface of a thin rectangular object. The distributions of the considered physical variables are obtained and represented graphically.

In this work, the authors develop a working software-based approach named ‘linearly quantile separated histogram equalisation-grey relational analysis’ for mammogram image (MI). This approach improves overall contrast (local and global) of given MI and segments breast-region with a specific end goal to acquire better visual elucidation, examination, and grouping of mammogram masses to help radiologists in settling on more precise choices. The fundamental commitment of this work is to demonstrate that results of good quality of breast-region segmentation can be accomplished from basic breast-region segmentation if the input image has good contrast and a better interpretation of hidden details. They have evaluated the proposed strategy for MIAS-MIs. Experimental results have shown that the proposed approach works better than state-of-the-art.

L10ordering at low temperature and controlled grain size are prerequisites for the fabrication of magnetic recording media. This can be achieved by several methods such as addition, under layer or over layer of third element in FePt. In the present work, the kinetics of L10 ordering in the presence of immiscible element Au is investigated by varying the Au concentration at different annealing temperatures. The structural analysis shows that the Au additive not only promotes the ordering at low temperature but also supports the textured growth along(001) plane. The magnetic measurements supported by theoretical simulations using Monte Carlo predicts that the enhancement in coercivity attributed to induced strain anisotropy and weakening of inter-granular exchange coupling may be due to presence of Au at grain boundaries.

A petroleum middle distillate, known as fog oil (FO), has been used in the United military battlefield to create obscurant smoke screens. During studies on the feasibility of replacing FO with relatively environmentally benign natural oil esters, with similar flow properties, such as methyl soyate (MS), it was observed that FO and MS aerosols and vapors were lethal to Salmonella typhimurium strains (Ames strains used to test for mutagenic activity in the Modified Ames Assay) even after very short exposures. It was further shown that vapors produced from the vegetable oil esters under certain conditions exhibited antimicrobial activity against a wide range of Gram-positive and Gram-negative bacteria. In this study, we examined the antimicrobial properties of volatile organic compounds detected in vegetable oil ester vapors. The experiments involved introduction of a known amount of specific compounds present in oil smoke vaors, individually and in combination, into an exposure chamber containing nutrient agar petri dishes inoculated with Salmonella typhimurium. Petri dishes were removed from the chamber after varied exposure periods to determine survival of the bacteria. The results of the experiments showed that individual compounds exhibited antimicrobial activity but lower than the vapors produced during thermal aerosol generation process suggesting the antimicrobial activity of the vapors is likely a synergistic activity of multiple components of the vapors.
