Background: Prevalence of peptic ulcer disease has been associated to diet. Some dietary factors seem to have bactericidal effect which may modify the risk of peptic ulcer disease. The objective was to analyze associations between dietary habits and peptic ulcers. Design: A cross sectional population study. Subjects: One thousand, one hundred and thirty-five subjects out of 11,700 randomly invited

Purpose: We evaluated the influence of urodynamic factors on the establishment of bacteriuria, after deliberate intravesical inoculation with Escherichia coli. Materials and Methods: Nine women and 7 men with recurrent symptomatic urinary tract infections underwent intravesical injection of E. coli 83972. This strain had documented ability to persist in the urinary tract and it lacks expressed vir

With the advent of cheap sensors and computing capabilities as well as better algorithms it is now possible to do structure from motion using crowd sourced data. Individual estimates of a map can be obtained using structure from motion (SfM) or simultaneous localization and mapping (SLAM) using e.g. images, sound or radio. However the problem of map merging as used for collaborative SLAM needs fur

Multiple system atrophy (MSA) is a rapidly progressive neurodegenerative disorder characterized by widespread oligodendroglial cytoplasmic inclusions of filamentous α-synuclein, and neuronal loss in autonomic centres, basal ganglia and cerebellar circuits. It has been suggested that primary oligodendroglial α-synucleinopathy may represent a trigger in the pathogenesis of MSA, but the mechanisms un

With growing traffic demands, transportation networks become more and more congested and prone to disruptions. In this paper, we study how different perturbations affect the free flow equilibria, i.e., equilibria where no congestion effects are present, in transportation networks. More specifically, if and when the equilibrium of the perturbed dynamics is still in free flow. A generalized cell tra

IntroductionSlow sand filtration is an established method for drinking water treatment, however, the knowledge about their microbial ecology remains limited. Maintenance of slow sand filters (SSF) includes washing to remove biofilm growth in the sand and restore flow through the filter. Understanding how this impacts produced water is important as the SSF may influence the bacterial flora in the f

In The 21st-Century Voice: Contemporary and Traditional Extra-Normal Voice, Michael Edward Edgerton considers contemporary vocal techniques within an acoustic and anatomical framework. Throughout, he proposes new directions for vocal exploration. Much more than a historical treatise on 20th-century masterworks or vocal science, The 21st-Century Voice explores experimental methods of sound producti

Translational regulation of ornithine decarboxylase (ODC), which catalyses the first step in the biosynthesis of polyamines, appears to be an important mechanism in the strong feedback control as well as in the hypotonic induction of the enzyme. However, the exact mechanisms are not yet understood. The ODC mRNA has long 5' and 3' untranslated regions (UTRs) which may be involved in the translation

Purpose - Logisticians have always viewed standards as solutions for improving operational compatibility and coordination. This paper aims to contribute to a greater understanding of how standards, upon which logistics systems are designed, developed and coordinated, interact with each other and with other resources in a logistics network for the purpose of improving efficiency and effectiveness.

Drinking water is delivered from the treatment plant to the consumer through kilometres of pipes. Lining these pipes are communities of bacteria living as biofilms. Little is known about the microbial ecology of these biofilms, as access to drinking water pipes for sampling is often limited to pipes sporadically removed for repair or replacement. Bacteria are constantly exchanged between the biofi

Governments in countries across the world increasingly adopt the “green growth” discourse to underline their ambition for the greening of their economies. The central tenet of this narrative is the economic opportunities rather than challenges arising from the pursuit of environmental sustainability. Our paper synthesises insights from 113 recent scientific articles, dealing with both environmenta
