Global competition has intensified geographic repositioning of supply chain activities with implications for the economic prosperity of specific regions and geographies affected by such shifts. This study examines the relationship between the level of corruption and economic growth using the supply chain and ARDL bounds test method. The data used are GDP, the level of corruption, foreign direct investment, government spending and inflation from 2000-2018. The results of the study indicate a negative and significant impact on the level of corruption on economic growth in the long run.

The purpose of the encapsulation of the research objectives into four stand-alone pieces was to enable specific aspects of the findings to be more readily accessed by future researchers and members of the teaching profession. Each piece corresponds to a research objective and reflects a research question. The research questions were formulated to tackle aspects of the research problem. The research outcomes could contribute to the growing body of knowledge about music activities delivered by classroom teachers.

The catalyst 7.5% NiO/TiO2 and seven samples of NiO/γ-Al2O3 with NiO content from 7.5% to 60% have been obtained and studied. Physico-chemical characteristics of the catalysts were determined by methods of Adsorption (BET), X-ray Diffraction (XRD), TemperatureProgrammed Reduction (TPR) and Hydrogen Pulse Titration. The catalytic properties of the obtained samples were investigated in the reaction of CO methanation at temperatures 180 – 220◦C and mole ratios hydrogen/carbon monoxide 25-100.

Regulator of G protein signaling (RGS) proteins are gatekeepers regulating the cellular responses induced by G protein-coupled receptor (GPCR)-mediated activation of heterotrimeric G proteins. Specifically, RGS proteins determine the magnitude and duration of GPCR signaling by acting as a GTPase-activating protein for Gα subunits, an activity facilitated by their semiconserved RGS domain. The R7 subfamily of RGS proteins is distinguished by two unique domains, DEP/DHEX and GGL, which mediate membrane targeting and stability of these proteins.

Through research of research projects in Vietnam and abroad related to the topic, the thesis shows that there are no works that comprehensively study theoretical and practical issues to ensure the right of proceeding of the litigants in civil proceedings in Vietnam. There is still only studies from the perspective of separate legal rights (but this number is also very small).

Formal specification of agent behaviour through environment scenarios introduces a formal notation for the specification of scenario s in agent based systems. The autonomous and collaborative behavior of an agent can be formally specified by a set of rules describing its activity in various scenarios. The power of the approach is illustrated by the formal specification of maes.

Vibrio choleraehemolysin (HlyA), a water-soluble protein with a native monomeric relative molecular mass of 65 000, forms transmembrane pentameric channels in target bio-membranes.TheHlyAbinds to lipid vesicles nonspecifically and without saturation; however, self-assembly is triggered specifically by cholesterol.Here we show that the HlyA partitioned quantitatively to amphiphilic media irrespective of their compositions, indicating that the toxin had an amphiphilic surface.

The serotype a-specific polysaccharide antigen ofActinoba-cillus actinomycetemcomitansis an unusual sugar, 6-deoxy-D-talose.Guanosinediphosphate (GDP)-6-deoxy-D-talose is the activated sugar nucleotide form of 6-deoxy-D-talose, which has been identified as a constituent of only a few microbial polysaccharides. In this paper, we identify two genes encoding GDP-6-deoxy-D-talose synthetic enzymes, GDP-a-D-mannose 4,6-dehydratase and GDP-4-keto-6-deoxy-D-mannose reductase, in the gene cluster required for the biosynthesis of serotype a-specific polysaccharide anti-gen from A.

Specificity for plastoquinone was observed. Neither ubiquinone, duroquinone, phylloquinone nor ben-zoquinone could substitute for plastoquinone in this assay. However, duroquinol (fully reduced chemically) was an accepted substrate. Iron is also required and cannot be substituted by Cu 2+ ,Zn 2+ or Mn 2+ . ...

The new antigen receptor (IgNAR) from sharks is a disul-phide bonded dimer of two protein chains,each containing one variable and five constant domains,and functions as an antibody. In order to assess the antigen-binding capabilities of isolated IgNAR variable domains (VNAR),we have con-structed anin vitro library incorporating synthetic CDR3 regions of 15–18 residues in length.

G-protein-coupled receptor kinase 2 (GRK2) is known to specifically phosphorylate the agonist-bound forms of G-protein-coupled receptors (GPCRs). This strict specificity is due at least partly to activation of GRK2 by agonist-bound GPCRs, in which basic residues in intracellular regions adjacent to transmembrane segments are thought to be involved. Tubulin was found to be phosphorylated by GRK2, but it remains unknown if tubulin can also serve as both a substrate and an activator for GRK2.

The selective manipulation of the expression and replica-tion of mitochondrial DNA (mtDNA) within mammalian cells has proven difficult. In progressing towards this goal we synthesized a novel mitochondria-targeted DNA-alkylating reagent. The active alkylating moiety [(11aS)-8-hydroxy-7-methoxy-1,2,3,11a-tetrahydro-5H-pyrrolo[2,1-c] [1,4]benzodiazepin-5-one (DC-81)], irreversibly alkylates guanine bases in DNA (with a preference for AGA tri-plets), preventing its expression and replication.

Antisense agents are valuable tools to inhibit the expression of a target gene in a sequence-specific manner,and may be used for functional genomics,target validation and thera-peuticpurposes.Three typesof anti-mRNAstrategies canbe distinguished. Firstly,the use of single stranded antisense-oligonucleotides; secondly,the triggering of RNA cleavage through catalytically active oligonucleotides referred to as ribozymes; and thirdly,RNA interference induced by small interfering RNA molecules.
