Visualising microstructural dynamics of titanium aluminium nitride coatings under variable-temperature oxidation

Understanding the link between titanium-aluminium nitride's (Ti1-xAlxN) physicochemical properties and structural dynamics during operation is essential to designing and fabricating advanced ceramic coatings. Here, we directly visualise the oxidation of Ti1-xAlxN (for x = 0, 0.18, 0.44, & 0.67) coatings from 100 to 1000 °C using environmental transmission electron microscopy (ETEM) imaging and

Detailed anatomy at 7T

Selected high resolution axial images obtained from a 7T MRI scanner have been labeled to provide detailed information about the subtle structures found in the cerebellum and brainstem.

Prevalence of asystole during tilt test-induced vasovagal syncope may depend on test methodology

This review addresses tilt-testing methodology by searching the literature which reports timing of asystole and loss of consciousness (LOC). Despite the Italian protocol being the most widely adopted, its stipulations are not always followed to the letter of the European Society of Cardiology guidelines. The discrepancies permit reassessment of the incidence of asystole when tilt-down is early, im

Cardiovascular Morbidity and Mortality Related to Non-Alcoholic Fatty Liver Disease : a Systematic Review and Meta-Analysis

BACKGROUND AND AIMS: Whether non-alcoholic fatty liver disease (NAFLD) is a cardiovascular (CV) risk factor is debated. We performed a systematic review and meta-analysis to assess the CV morbidity and mortality related to NAFLD in the general population, and to determine whether CV risk is comparable between lean and non-lean NAFLD phenotypes.METHODS AND RESULTS: We searched multiple databases, i

Getting at the Experience of Confinement in Detention

A distinguishing feature of youth detention homes—and any other prisonlike institution—is the fact that inmates cannot just leave. They might escape, and there are ways to be transferred, enjoy an excursion, and get permission for home visits, but typically the young people in this case are supposed to remain within their given institution. I have been eager to not only depict this feature of fielA distinguishing feature of youth detention homes—and any other prisonlike institution—is the fact that inmates cannot just leave.

Development of new railway timetabling rules for increased robustness

Due to high demand and capacity consumption, railway timetables are often sensitive to disturbances. To maintain punctual operations, it is important that timetables are robust, and methods are needed that make them robust without consuming too much capacity. In this paper, we demonstrate how a policy change in the form of new timetable planning rules can be used to achieve more robust timetables.

Gut Microbiome Composition in Dystonia Patients

Dystonia is a movement disorder in which patients have involuntary abnormal movements or postures. Non-motor symptoms, such as psychiatric symptoms, sleep problems and fatigue, are common. We hypothesise that the gut microbiome might play a role in the pathophysiology of the (non-)motor symptoms in dystonia via the gut-brain axis. This exploratory study investigates the composition of the gut micr

S100B predicts neurological injury and 30-day mortality following surgery for acute type A aortic dissection : an observational cohort study

Background: Neurological injuries are frequent following Acute Type A Aortic Dissection (ATAAD) repair occurring in 4–30% of all patients. Our objective was to study whether S100B can predict neurological injury following ATAAD repair. Methods: This was a single-center, retrospective, observational study. The study included all patients that underwent ATAAD repair at our institution between Jan 19

Carbon taxes and agriculture: the benefit of a multilateral agreement

Reducing greenhouse gas emissions from agriculture is crucial to reach global and regional climate targets. However, the efficiency of unilateral climate policies aimed at taxing emissions might be hampered by carbon leakage. One way to eliminate leakage is to implement a global carbon tax. In this article, we study the effects of a carbon tax in agriculture on GHG emissions by simulating five polReducing greenhouse gas emissions from agriculture is crucial to reach global and regional climate targets.

Sulfidation of Supported Ni, Mo and NiMo Catalysts Studied by In Situ XAFS

Active sites in Mo-based hydrotreating catalysts are produced by sulfidation. To achieve insights that may enable optimization of the catalysts, this process should be studied in situ. Herein we present a comparative XAFS study where the in situ sulfidation of Mo/δ-Al2O3 and Ni/δ-Al2O3 is compared to that of δ-Al2O3 supported NiMo catalysts with different NiMo ratios. The study also covers the com

Impact of silencing eEF2K expression on the malignant properties of chordoma

Background: Eukaryotic elongation factor 2 kinase (eukaryotic elongation factor 2 kinase, eEF2K) is a calcium calmodulin dependent protein kinase that keeps the highest energy consuming cellular process of protein synthesis under check through negative regulation. eEF2K pauses global protein synthesis rates at the translational elongation step by phosphorylating its only kown substrate elongation

Mindre här men mer där – problemet med läckage av växthusgaser inom jordbruket

Sverige och EU har satt upp ambitiösa mål för att minska utsläppen av växthusgaser. Jordbruket står för en stor del av utsläppen och kraftfulla styrmedel behövs. Samtidigt sker handel med jordbruksprodukter på världsmarknaden, vilket innebär att styrmedel som visserligen minskar utsläppen i Sverige och EU också kan leda till att produktion och utsläpp ökar utanför EU – så kallat utsläppsläckage.
