Background: Baker's yeast (Saccharomyces cerevisiae) has been engineered for xylose utilization to enable production of fuel ethanol from lignocellulose raw material. One unresolved challenge is that S. cerevisiae lacks a dedicated transport system for pentose sugars, which means that xylose is transported by non-specific Hxt transporters with comparatively low transport rate and affinity for xylo
Introduction: Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes increasingly difficult during rotational movements. We aimed to evaluate five different methods (metrics) of processing acceleration signals on their ability to
Background: Xylose reductase (XR) and xylitol dehydrogenase (XDH) from Pichia stipitis are the two enzymes most commonly used in recombinant Saccharomyces cerevisiae strains engineered for xylose utilization. The availability of NAD+ for XDH is limited during anaerobic xylose fermentation because of the preference of XR for NADPH. This in turn results in xylitol formation and reduced ethanol yield
This entry is intended to provide the reader with an overview of the central themes and arguments found in David Hume's (1711–1776) contributions to the philosophy of religion. The topics covered include the argument from design and the cosmological argument; the problem of evil; miracles and revealed religion; the natural history of religion; and Hume's philosophy of irreligion and atheism.
Our world is changing fast. On one hand, technological developments provide us with new and powerful electronics devices on almost a weekly basis. On the other hand, the end-user of these electronics is now rarely required to actually configure the devices, as everything is automated. This "de-empowerment" of the end-user may be detrimental to the scientific community. This is because the unique c

Barn med språkstörningar har problem med att tillägna sig sitt förstaspråk – trots normal hörsel och kognitiv förmåga. Tvärspråklig forskning om grammatiska problem har visat att problemen ser olika ut i olika språk. Detta gör det svårt att diagnosticera flerspråkiga barn. I den här artikeln föreslås Processbarhetsteorin (Pienemann 1998, 2015) som metod för att kartlägga språkutvecklingen hos alla
Objective. Previous research has shown that elderly and disabled travelers using Special Transportation Services (STS) are injured without being involved in a vehicle crash. In order to estimate the true costs for these vehicle-related injuries, the focus needs to be adjusted towards an incident/traveler-oriented perspective. The aim of the project was thus to utilize such a perspective, in order
