introduction and aims: until today human stomach is the only recognized habitat of h. pylori . however, recruitment of dna-based methods has made possible the detection of h. pylori in water and oral cavity, thus suggesting faecal-oral and oral-oral routes for transmission of h. pylori , respectively. in this study yeast has been proposed as a common vector for transmission of h. pylori . thus ...

Abstract International supply chains are dependent on ease of crossing borders and efficient connectivity in terms price, speed, reliability. Communication costs explain why intensification international during the last 4 decades has occurred primarily within regional value (RVCs), centered East Asia, Europe, North America. Initially responding to demand from automobile electronics firms connec...

Chronic total occlusions (CTOs) represent the "last frontier" of percutaneous interventions. The main technical challenges lies in crossing the guidewire into the distal true lumen, which is primarily due to three problems: device buckling during initial puncture, inadequate visualization, and the inability to actively navigate through the CTO. To improve the success rate and to identify future...

Mitigation measures for downstream-migrating Atlantic salmon smolts (Salmo salar L.) are commonly insufficiently attractive to enable safe entrance and passage with no delay. Combining 2D telemetry hydrodynamic modelling has been shown be a good tool better understand the influence of factors on migration route choice fishes. In this study, we investigated smolt downstream at hydropower plant i...

the effects of various routes of probiotic administration on performance, small intestine morphology and serum cholesterol of broiler chickens, were studied. we assigned 225 day old chicks (ross 308) to five experimental groups including control and four hatchery administration methods comprised of in ovo injection, oral gavage, spray application and cloacal inoculation. all of these were chall...

This paper evaluates the effect of a large-capacity electrical energy storage, e.g., Li-ion battery, on optimal sailing routes, speeds, fuel choice, and emission abatement technology selection. Despite rapid cost reduction performance improvement, current chemistries are infeasible for providing total demand ocean-crossing ships because density is up to two orders magnitude less than in liquid ...
