• Serological and molecular techniques for the diagnosis of BrucellosisSerological and molecular techniques for the diagnosis of Brucellosis

    CONCLUSION The diagnosis of brucellosis in humans and livestock is not an easy task. The “gold standard” of Brucella identification is the recovery of the agent from the host, but it is time consuming and laborious method. Which can be done in highly equipped laboratories. For the diagnosis of brucellosis serological test has been developed ...

  • Determination of the concentration of Fe, Se, and Zn elements in nails of Vietnamese women with breast cancer using k0-INAA methodDetermination of the concentration of Fe, Se, and Zn elements in nails of Vietnamese women with breast cancer using k0-INAA method

    CONCLUSION The present study k0-INAA method was used to determine the concentrations of Fe, Se, and Zn in fingernail samples of women with breast cancer and healthy women. In the elements determined, the concentration of Fe was found a much higher level in women with breast cancer than those of healthy women, while the concentration of the elem...

  • Cominimax modules and generalized local cohomology modulesCominimax modules and generalized local cohomology modules

    The following result shows a connection on the Icominimaxness of Hi I(N) and HIi(M;N) when R is not a local ring and N is an arbitrary R-module. Theorem 2.9 Let M be a finitely generated R-module with pd(M) < ¥ and N an R- module. Let I be an ideal of R with dimR=I = 1 and t a non-negative integer such that Hi I(N) is I-cominimax for all i <...

  • Characterization of the silver thin films produced at different substrate temperaturesCharacterization of the silver thin films produced at different substrate temperatures

    CONCLUSIONS In summary, we have investigated the antimicrobial activity of Ag NPs films prepared by DC magnetron sputtering technique. Their optical properties were analyzed by UV-Vis spectroscopy, while, the structure and morphological properties were investigated by XRD, FE-SEM, and AFM, respectively. Besides, their antimicrobial efficacy i...

  • Four flavonols from the seed of Hibiscus sabdariffa Linn growing in Binh Thuan provinceFour flavonols from the seed of Hibiscus sabdariffa Linn growing in Binh Thuan province

    Compound 1 was obtained as a yellow amorphous powder. The NMR spectra of 1 revealed characteristic signals of a flavonol skeleton. Indeed, the 1 HNMR spectrum of 1 showed a hydroxyl group at d 12.58 (1H, s) which was assigned to 5-OH of a 5,7- dihydroxy A ring system in flavonoid while two meta –coupled protons at dH 6.19 (1H, d, 2.0, H-6) and ...

  • Asymptotic behaviors with convergence rates of distributions of negative - Binomial sumsAsymptotic behaviors with convergence rates of distributions of negative - Binomial sums

    DISCUSSIONS In some situations, it is quite hard to establish the limiting distributions for negative-binomial sums of i.i.d. random variables. Meanwhile, if the limiting distribution of the partial sum is stated, the limiting distribution of corresponding negative-binomial sum will be established by the Gnedenko’s Transfer Theorem (see10). Thu...

  • A new earthworm of the genus pheretima (oligochaeta: megascolecidae) from the mekong delta of vietnam and taxonomical position of pheretima polychaetifera Thai, 1984A new earthworm of the genus pheretima (oligochaeta: megascolecidae) from the mekong delta of vietnam and taxonomical position of pheretima polychaetifera Thai, 1984

    In 1984, Thai Tran Bai published a new species to science among specimens collected in Long An Province. This new species has setal zone behind male pore areas, which is a very specific characteristic. Therefore, he called it Pheretima polychaetifera. When comparing this species with some different species which have similar setal zones, we beli...
