Pathogenic and commensal bacteria that experience limited nutrient availability in their host have evolved sophisticated systems to catabolize the mucin sugar N-acetylneuraminic acid, thereby facilitating their survival and colonization. The correct function of the associated catabolic machinery is particularly crucial for the pathogenesis of enteropathogenic bacteria during infection, although...

Schizophrenia is a complex mental disorder caused by an interplay between genetic and environmental factors, including early postnatal stressors. To explore this issue, we use two rat lines, apomorphine-susceptible (APO-SUS) rats that display schizophrenia-relevant features and their phenotypic counterpart, apomorphine-unsusceptible (APO-UNSUS) rats. These rat lines differ not only in their gna...

Stability of the retained goaf-side gateroad (RGSG) is influenced mainly by the movements of the roof strata near coal seam after coalface passes by. To make effective controlling technology for the stability of the RGSG, we analyze the roof structure over the RGSG to illustrate the mechanism causing the RGSG instability under different roof conditions. We then examine the dynamic evolution of ...

Thermal benefits of different green roof samples were analyzed and compared. Experimental data from ongoing green roof projects was used in a theoretical analysis of air-conditioning energy savings with different green roof applications. Thermal data was collected from a typical non-reflective (EPDM) roof membrane and model green roof systems with three types of growth media (lava, arkalyte, an...

OBJECTIVES AND AIM The objective of this study was to determine the origin of an arched back in cows during vaginal examination. Moreover, we tested whether the duration of an arched back and avoidance reactions during vaginal examination can be decreased by epidural anaesthesia or analgesic treatment. MATERIAL AND METHODS Behaviour during cleaning of the perivaginal region and during vaginal...

The construction of public buildings from a metal frame is always associated with the search for rational constructive solution that meets not only dependability requirements, safety, but also architectural and design solutions. Often, to problem rationalization roof in use arched combined systems, since such systems have number advantages over simple arches: survivability higher than ones, pos...

Current research trends in significant hydraulic engineering projects focus on investigating the seismological properties of intensity and frequency content pulse-type near-field earthquakes structural response. Conversely, duration impact is not expressly addressed seismic design code for underground buildings. Currently, various indicators as-recorded strong ground motions mainly consider eff...

BACKGROUND The medial longitudinal arch of the foot is important because it helps protect the foot from injury. Researchers have developed many measures to quantify the characteristics of the arch, and there is ongoing debate about the suitability of these different metrics. This article compares the various measures related to the foot arch, including a new metric, the midfoot dorsal angle, an...

Abstract The structure of parabolic condensers makes them susceptible to wind load because their thin and large windward mirrors. In this paper, the pressure on a model condenser mirror (1:35) multistorey flat roofs is analysed via measurement in tunnel. mean wind-pressure distribution law flat-roof mirrors (including change with working conditions maximum characteristics) fluctuating extreme a...
