Eléments de description du ngangela

Cette étude donne une esquisse de la phonologie, de la majeure partie de la morphologie et de la syntaxe du ngangela, variété parlée à Kuvango (Sud-est de l'Angola) et classée K b12 par M. Guthrie. Elle comporte trois chapitres. Dans le premier chapitre, elle étudie les unités phonologiques de la langue sur le plan segmental et donne un aperçu sur le statut du système prosodique et sur sa morphophonologie segmentale. Dans le deuxième chapitre, elle aborde l'étude des morphèmes qui s'associent aux lexèmes nominal, verbal, adjectival et aux référents. Le troisième chapitre, consaré à la syntaxe, aborde les mécanismes de détermination. Il présente également les phrases à prédicat verbal et phrases sans prédicat verbal. Enfin, il dégage le type spécifique de construction passive et les mécanismes de topicalisation et de focalisation en usage dans la langue.This study deals with the structure of ngangela, Bantu language (k b12), spoken in Kuvango (South-eastern of Angola). In the first chapter, it studies the phonological units at segmental level of the language and examines briefly the tonal units. It analyses also the segmental morph phonological units. The second chapter is devoted to the morphemic study of the constitutive of the noun, the verb, the adjective and the determiners. The third chapter deals with the syntactic features of the language, particularly the determination mechanism and the way it works. It also presents the basic sentence structure of he language, the predication (both nominal and verbal), the topicalization and focalisation processes and the specific kind of passive construction (pseudo-passive construction) in the language.LYON2/BRON-BU (690292101) / SudocSudocFranceF

Adherence of staphylococcus aureus to catheter tubing inhibition by quaternary ammonium compounds

Introduction: S. aureus is a Gram positive bacterium which is responsible for a wide range of infections. This pathogen has also the ability to adhere to biotic or abiotic surface such as central venous catheter (CVC) and to produce a biofilm. The aim of this study was to evaluate the effect of hexadecyltrimethyl ammonium bromide (HTAB) and Hexadecylbetainate chloride (HBC) on Staphylococcus aureus adherence to the catheter tubing and on bacteria growth. Methods: broth microdilution method was used to determine the Minimal Inhibitory Concentration (MIC). The detection of slime production was done by Congo Red Agar method, and the adherence of bacteria to the catheter tubing was evaluated by the enumeration of bacteria on plate counts. Results: the results of this study showed that the MICs of HTAB were ranged from 0.125 to 0.5 µg/mL, and those of HBC fluctuated between 2 to 8 µg/mL. HTAB and HBC inhibited bacteria adhesion on the surface of the catheter tubing. Conclusion: this study showed that HTAB and HBC can prevent the adherence of S. aureus strains to the surface of catheter tubing, suggesting that they could be used to prevent the risk of catheter related bloodstream infections.
