objective: vancomycin-resistant enterococci (vre) have emerged worldwide and have become an increasing problem in clinical settings. acquired glycopeptide resistance in enterococcus species is due to the acquisition of van a, van b, van d, van c and van e genes, resulting in the production of peptidoglycan precursors with reduced affinity for glycopeptide antibiotics. the origin of these van ge...

in this study a simple and general chemical association theory is introduced. the concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. the theory is applied to derive the distribution function of associated species. as a severe test the application of presented theory to the van der waals mixture model is introduced in order to perfo...

Macrostructure of sleep During sleep, 5 to 6 sleepcycles occur during the night, lasting approximately 1,5 hours. Every sleep cycle consists of one REM stage, characterised by rapid eye movements, paradoxical cortical activation and muscular atonia, and four non-REM stages (‘macrostructure’ of sleep). The first three to five hours of the night are considered to be most important and responsible...

this article was written based on the key concept of polysystem theory which, in translating any literary text, emphasizes the transference of the social systems in which a text is embedded. as stated by tynjanov (1978a), polysystem theory saw translated literature as a system operating in the larger social systems of the target text. thus, the task of understanding as well as transferring such...

Comprehension and learning with hypertexts is challenging due to the nonlinearity of such digital documents. Processing hypertexts may involve navigation and comprehension problems, leading learners to cognitive overhead (DeStefano & LeFevre, 2007). Concept maps have been added to hypertexts to reduce the cognitive requirements of navigation and comprehension. The current chapter explores the l...

Growth hormone (GH) deficiency is related to an increased fracture risk although it is not clear if this is due to compromised bone quality or a small bone size. We investigated the relationship between bone macrostructure, microarchitecture and mechanical properties in a GH-deficient (GHD) mouse model undergoing GH treatment commencing at an early (prepubertal) or late (postpubertal) time poin...

PURPOSE To evaluate the clinical utility of the narrative scoring scheme (NSS) as an index of narrative macrostructure for young school-age children. METHOD Oral retells of a wordless picture book were elicited from 129 typically developing children, ages 5-7. A series of correlations and hierarchical regression equations were completed using microstructural measures of vocabulary and grammar...
