The demand for cost- and time-effective and customizable components for High Vacuum (HV) and Ultra-High Vacuum (UHV) systems has prompted exploration into the application of 3D-printing technology. This study investigates the viability of utilizing 3D-printed plastics in UHV environments by evaluating their outgassing properties. An extensive evaluation of 3D-printing materials was carried out, hi

A limitation of current LoRa networks is their single-hop nature. This causes difficulties in areas with poor Internet access, such as remote rural areas, or challenging radio environments, for example in metropolitan areas, as the LoRa gateway must be placed at a location with backhaul access to the network server, but must nonetheless be reachable by all end devices. To facilitate these applicat

Two central steps in the hydrolysis of lactam antibiotics catalyzed by mononuclear metallo--lactamases, formation of the tetrahedral intermediate and its breakdown by proton transfer, are studied for model systems using the density functional B3LYP method. Metallo--lactamases have two metal ion binding sites, one of which is occupied in the mononuclear species. In this work it is assumed that cata

ABSTRACT Introduction: A wireless BRAVO() (Medtronic, Shoreview, MN) capsule for pH measurement in the diagnosis of gastroesophageal reflux disease (GERD) is intended to be less uncomfortable, and facilitates activity during the measuring period, compared to the usual method with a naso-esophageal catheter. The aim of this study was to report on our experience with the wireless system in children.

Introduction: The prognosis of patients at the pre-dementia stage is difficult to define. The aim of this study is to develop and validate a biomarker-based continuous model for predicting the individual cognitive level at any future moment. In addition to personalized prognosis, such a model could reduce trial sample size requirements by allowing inclusion of a homogenous patient population. Meth

When Jean-Francois Mayet was elected mayor of the French city of Châteauroux in 2001, he inherited a mass transit system that was functional but under-used by residents. The city, located about halfway between Paris and Bordeaux, had collective aims that were similar to other medium-sized cities in Europe: to reduce the city’s ecological footprint while improving the local economy and fostering a

Placebo comparisons are increasingly being considered for randomised trials assessing the efficacy of surgical interventions. The aim of this Review is to provide a summary of knowledge on placebo controls in surgical trials. A placebo control is a complex type of comparison group in the surgical setting and, although powerful, presents many challenges. This Review outlines what a placebo control

Streams draining agricultural land are simultaneously exposed to multiple stressors including agricultural antibiotics and effluent from surface water run-off. The potential interactive effects of these contaminants on stream benthic communities are poorly understood. Using a streamside channel experiment with a full factorial, repeated-measures design, we assessed the individual and combined effe

Audio description (AD) serves a critical role in making film narratives accessible to visually impaired audiences, aiming to enhance their viewing experience and comprehension. One method to assess the comprehension of film narratives, is through an event segmentation task, wherein participants delineate the narrative unfolding into distinct meaningful events.

The worldwide adoption of renewable energy mandates, together with the widespread utilization of biofuels has created a sharp increase in the production of biodiesel (fatty acid alkyl esters). As a consequence, the production of glycerol, the main by-product of the transesterification of fatty acids, has increased accordingly, which has led to an oversupply of that compound on the markets. Therefo

Cooperation initiatives across national borders is growing phenomenon all over the world due to developing globalization and regionalization. Growing trend of spatial reorganization of production process, massive growth of markets and labor recourses, opportunities to “escape” from spatial and resource dependencies are stimulating international cross-border interactions and emergence of cross-bord

I ett entreprenadavtal regleras det normalt huruvida det är beställaren eller entreprenören som ska bära ansvaret för att en entreprenad försenats. En situation som mer sällan regleras är vem av parterna som ska bära risken om det föreligger konkurrerande förseningsorsaker. Avsikten med förevarande framställning är därför att analysera hur en domstol skulle bedöma en entreprenörs krav på tidsförläNormally, the contract governing a construction project regulates whether the contractor or the employer shall bear the risk of a delay. Nevertheless, the parties rarely include in their contract provisions how liability for concurrent delays should be dealt with. Therefore, the purpose of this thesis is to examine how the Swedish courts would treat claims from a contractor for an extension of tim
