Elektrolys som komplement till reformering av metan Elektrolys och reformering av metan är metoder för att producera vätgas. Kan en elektrolysör adderas till en reformeringsanläggning och minska både koldioxidutsläpp och produktionskostnader? Elektrolys sker då vattenmolekylerna splittras med hjälp av el till väte och syre, detta görs med en elektrolysör. För att analysera fördelarna av att komple

BACKGROUND: Parkinson's disease (PD) is a chronic neurodegenerative disorder with limited knowledge about the normal function and effects of non-pharmacological therapies on the hypothalamic-pituitary-adrenal (HPA) axis. The aim of the study was to analyse the basal diurnal and total secretion of salivary cortisol in short- and long-term aspects of tactile massage (TM).DESIGN: Prospective, Control

BACKGROUND: Recurrent stroke is a frequent, disabling event after ischemic stroke. This study compared the efficacy and safety of two antiplatelet regimens--aspirin plus extended-release dipyridamole (ASA-ERDP) versus clopidogrel.METHODS: In this double-blind, 2-by-2 factorial trial, we randomly assigned patients to receive 25 mg of aspirin plus 200 mg of extended-release dipyridamole twice daily

Svensk byggindustri genomgår en strukturomvandling och byggföretag väljer nuförtiden i stor utsträckning att använda sig av underentreprenörer i strävan efter organisatorisk flexibilitet. Genom etnografiska observationer och intervjuer från byggarbetsplatser analyserar jag hur arbetet organiseras inom två byggföretag och hur de resonerar i sin användning av underentreprenörer. Med utgångspunkt i o

The minority stress model has become a well-used framework to explain and analyse health among LGBTQ people, and specifically among transgender and gender-diverse people (TGD), when it is sometimes called ‘the gender minority stress model’. Scholars have argued the need for critical discussions about some of the assumptions underlying the gender minority stress model and how it has been used and d

In Schacter (2022), the author outlines the considerable progress that has been made in characterizing the impact of five (of the seven) sins of memory; specifically, transience, absentmindedness, misattribution, suggestibility, and persistence. As in his influential book, The Seven Sins of Memory: How the Mind Forgets and Remembers (Schacter, 2001, 2021), Schacter notes that this last sin of pers

Amyloid proteins are species whose aggregation has been associated with various neurodegenerative diseases. While intrinsically disordered in their monomeric form, they tend to aggregate into highly ordered β-sheet rich fibrils. Nevertheless, many studies indicate that intermediate species known as amyloid oligomers, which are linked to neurotoxicity, may be the connection between amyloid proteins

Loss-of-function variants in the PRKN gene encoding the ubiquitin E3 ligase PARKIN cause autosomal recessive early-onset Parkinson's disease (PD). Extensive in vitro and in vivo studies have reported that PARKIN is involved in multiple pathways of mitochondrial quality control, including mitochondrial degradation and biogenesis. However, these findings are surrounded by substantial controversy due

In this thesis a fairly self-contained introduction to Thompson’s groups and a few of its related groups are given. The groups F , T and P LF (R) and some of their subgroups are discussed extensively. Finally, some interesting topics one could study after reading this thesis are summarized

Zygaenidae, also known as burnet, forester, smoky, or leaf skeletonizer moths, are a family of mainly diurnal moths well known for their aposematic colouration and the ability to release hydrogen cyanide as a defence mechanism. So far, few attempts have been made to understand the evolutionary history of the global zygaenid fauna. Here, we inferred the most comprehensive molecular phylogeny for Zy

During the last decade, the application of strontium isotope analysis (87Sr/86Sr) has increased rapidly. The understanding of the strontium isoscape and the construction of a strontium isotope baseline in southern Scandinavia are biased toward Denmark and southwestern to eastern Scania. We report the results of new baseline samples in Halland and the Bjäre Peninsula, adding to the rich strontium i

Testing autonomous driving systems for safety and reliability is essential, yet complex. A primary challenge is identifying relevant test scenarios, especially the critical ones that may expose hazards or harm to autonomous vehicles and other road users. Although numerous approaches and tools for critical scenario identification are proposed, the industry practices for selection, implementation, a

A fundamental framework to describe nuclear matter as a function of pressure and nuclear isospin asymmetry is the nuclear Equation of State (EoS). Constraining the parameters of the EoS is one of the central issues in nuclear physics, especially since the slope parameter L has not yet been constrained well experimentally. It has been identified that a precise determination of the neutron-removal c

Background: To date, studies investigating the association between pre-biologic biomarker levels and post-biologic outcomes have been limited to single biomarkers and assessment of biologic efficacy from structured clinical trials. Aim: To elucidate the associations of pre-biologic individual biomarker levels or their combinations with pre-to-post biologic changes in asthma outcomes in real-life.

Plant health promoting organisms, including microbial biological control agents, are of increasing importance for the development of more sustainable agriculture. To understand the function of these microbes as biological control agents under field conditions and their overall impact on soil and plant health, we need to learn more about the impact of plant beneficial microbes on the rhizosphere mi

We introduce the concept photophysical image analysis (PIA) and an associated pipeline for unsupervised probabilistic image thresholding for images recorded by electron-multiplying charge-coupled device (EMCCD) cameras. We base our approach on a closed-form analytic expression for the characteristic function (Fourier-transform of the probability mass function) for the image counts recorded in an E
