• Design of magnetron co-Sputtering configuration for preparing magnesium tin silicide-based thermoelectric alloy thin filmsDesign of magnetron co-Sputtering configuration for preparing magnesium tin silicide-based thermoelectric alloy thin films

    Initial results of the MgSiSn thin films Figure 2 shows the crystalline structure of the MgSiSn thin films. There are two peaks at 33.18o and 47.92o which belong to the (200) and (220) plane of the Si substrate, respectively. A clear peak located at ~34.50o is found to be the (002) plane of metal Mg phase (JCPDS 35-0821). The existence of a se...

  • Chemical constituents and the inhibition of a-Glucosidase of Gynura procumbens (Lour) MerrChemical constituents and the inhibition of a-Glucosidase of Gynura procumbens (Lour) Merr

    DISCUSSION Previous studies have shown that G. procumbens contains many compounds such as steroids, flavonoids, saponins, tannins, terpenoids, etc2. Among the seven compounds isolated, five compounds were known in G. procumbens syringic acid (1) (hydroxybenzoic acid structure), quercetin (2) (flavonoid glycoside structure), b-sitosterol 3-O-b...

  • Using edge elements for modeling of 3-D magnetodynamic problem via a subproblem methodUsing edge elements for modeling of 3-D magnetodynamic problem via a subproblem method

    The 3-D dimensional mesh with edge elements is depicted in Figure 4. The problem with the coil alone is first considered. The distribution of magnetic flux density generated by the excited electric current in the coil is pointed out in Figure 5. The computed results on the of the z-component of the magnetic flux density along the lines A1-B1 and...

  • Inhibition of protein expression by the interaction of G-Quadruplex and RHAU peptide in E. coliInhibition of protein expression by the interaction of G-Quadruplex and RHAU peptide in E. coli

    DISCUSSION Formation of G4 plays a role in many biological processes such as replication, transcription, translation and telomeric maintenance. The stabilization of G4 structure by peptide has recently emerged as a potential approach in the regulation of protein expression. RHAU peptide can selectively bind and stabilize G4 structure via elect...

  • 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...

    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 <...
