    Opis:
    The effect of magnetic field dependent (MFD) viscosity on thermal convection in a horizontal ferromagnetic fluid layer has been investigated numerically. A correction is applied to Sunil et al. [24] which is very important in order to predict the correct behavior of MFD viscosity. Linear stability analysis has been carried out for stationary convection. The MFD viscosity parameter δ as well as the measure of nonlinearity of magnetization M3, both have a stabilizing effect on the system. Numerical results are also obtained for large values of magnetic parameter M1 and predicted graphically.

    Opis:
    The onset of convective instability is analysed in a rotating multicomponent fluid layer in which density depends on n stratifying agents (one of them is heat) having different diffusivities. Two problems have been analysed mathematically. In the first problem, a sufficient condition is derived for the validity of the principle of the exchange of stabilities. Further, when the complement of this condition holds good, oscillatory motions of neutral or growing amplitude can exist, and thus it is important to derive upper bounds for the complex growth rate of such motions when at least one of the bounding surfaces is rigid so that exact solutions of the problem in closed form are not obtainable. Thus, as the second problem, bounds for the complex growth rates are also obtained. Above results are uniformly valid for quite general nature of the bounding surfaces.

    Opis:
    In the present study, we described the protein profile experimentally by 2D-PAGE and MALDI analysis to understand the stress mechanisms of cocoti sap and wine on E.coli Nissle 1917. We isolated one newly expressed protein from cocoti wine treated gel which is not present in both control and cocoti sap treated sample i.e. P21 prophage-derived head-stabilizing proteinVG03_ECOL6 (3n1) also called as Head protein gp3. This protein mainly activities related to the viral life cycle. It helps to attach the viral gene into host. The growth rate was delayed in cocoti wine treated E.coli Nissle 1917 when compared to control and cocoti sap treated samples. Stress mechanism induce many proteins they are involved in metabolic process, hydrolase activity, lyase activity, quinone binding, phosphotransferase system, carbohydrate metabolism, DNA binding, DNA repair, transferase activity, oxidoreductase, purine metabolism, transcription antitermination, transcription regulation and other related activities. We proved that the predicted protein structure quality, resolution, density and error plot values by QMEAN analysis. Based on these results, only two differentially expressed proteins under sap stress showed that the significant results, which were N-acetylgalactosamine-specific phosphotransferase enzyme IIB component 1, PTPB1_ECOLI and DinI-like protein Z3305/ECs2939 in prophage CP-933VDINI1_ECO57. In case of wine stress, the differentially expressed proteins were Transcription anti-termination protein RFAH- ECO57 NusA and PUR7- eco24- phosphoribosylamidazole-succinocarboxamide synthase showed significant results. ProtParam analysis indicating that the multiple physico-chemical characters of differentially expressed proteins were differed and compared. The phylogenetic tree represents the relationship in-between the differentially expressed proteins, were showed siblings (related) as well as monophytic clade.

    Opis:
    Proteomics is the large scale of study of proteins, particularly their function and structure. Proteomics is an excellent approach for studying changes in metabolism in response to different stress conditions. In the present review focused on different types of techniques for the analysis of expressed proteins. The techniques includes 2-D gel electrophoresis, MALDI-TOF/MS etc., play a vital role for the analysis of novel proteins and their role in disease maintenance and treatment. The review also concentrated on applicative perspective of proteomics in the fields of biomedical, agriculture and food.

    Opis:
    Crab meat is an excellent source of minerals, particularly calcium, iron, zinc, potassium and phosphours. The minerals in the edible parts of muscle of C.lucifera different sexes (male, female and berried female) were determined by digital flame photometer. Totally 11 minerals are reported in the present study. Seven (Sodium> Potassium >Magnesium >Calcium>Manganese> Iron >Zinc) minerals were reported in all sexes. Sodium was maximum (137.55 mg) and zinc was minimum (1.76 mg) in all sexes. Copper, mercury and cadmium were available in trace amount in all sexes. However, arsenic was in trace amount in berried females and totally absent in males and females. Among different sexes, berried females contain maximum amount of minerals (156.24mg) followed by females (121.76 mg) and males (95.5mg).

    Opis:
    Bisphenol A (BPA) is a plastic ingredient produced in large quantities for use primarily in the production of polycarbonate plastics and epoxy resins. The present review focused on different mechanisms of BPA on human health in enzymatic, androgenic, neurological, liver and reproductive systems. The review explained the influence of BPA on different stages of human life likely in foetal stage, children and adults stages. The review also concentrated on how to handle BPA, treatment, preventive measures against BPA exposure.
