Background: Osteoporosis is an underdiagnosed and undertreated disease worldwide. Recent studies have highlighted the use of simple vertebral trabecular attenuation values for opportunistic osteoporosis screening. Meanwhile, machine learning has been used to accurately segment large parts of the human skeleton. Purpose: To evaluate a fully automated deep learning-based method for lumbar vertebral

The Gaia-ESO Survey is a public spectroscopic survey that targeted ≲105 stars covering all major components of the Milky Way from the end of 2011 to 2018, delivering its final public release in May 2022. Unlike other spectroscopic surveys, Gaia-ESO is the only survey that observed stars across all spectral types with dedicated, specialised analyses: from O (Teff ∼ 30 000-52 000 K) all the way to K

BACKGROUND: The objective of this study was to evaluate anaesthesia care professionals' perceptions and attitudes regarding the implementation and advancement of digital solutions in perioperative care.METHODS: Anaesthesia personnel working in public Swedish institutions where anaesthesia is administered were invited to respond to an online survey regarding their attitudes towards digitalization i

Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial pro

Failure in wood is commonly considered as a sign of properly chosen adhesive for wood adhesive joints. It is argued that as the adhesive is stronger than the surrounding wood material, no concern has to be given to the adhesive properties in joint design. However, by means of theoretical arguments in combination with experimental experience in the present study, it is stated that local bond line p

Popular Abstract in Swedish Vetskap om strömning av vätskor och gaser är viktigt i dagens samhälle, vilket inkluderar transport i rör, förbränning, och flödesinducerade vibrationer. På grund av sin flyktiga form är möjligheten att kontrollera flöden i diverse applikationer begränsad. Strömning kan vara väldigt svårt att beskriva och kategorisera, speciellt då höga hastigheter är inblandade. HastigThis thesis presents the utilization of two different decomposition techniques, proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), for enhanced understanding of flow structures and their stability. The advantages of these techniques are shown for a range of flow situations, most of which are turbulent. It is shown that by these methods additional insight into complex flow

A new technology has emerged the last decade, based on a new group of materials; Soft Magnetic Composites (SMC), instead of laminated steel that facilitates production of products with more integrated, smaller, lighter, less costly and highly efficient electromagnetic machines. The application of this technology is a change of paradigm regarding integrated design and energy efficiency. This articl

The state-of-the-art in development tools today provides users with a large number of both syntactic and semantic services, such as syntax highlighting, name completions and refactorings. Preferably, every language should have sophisticated tool support, but unfortunately, the manual task of tool development is both time-consuming and error-prone, making it too costly for small language communitie

Ergonomics are, in most cases, focusing on the human being when evaluating assembly system designs. This results in the human performance being expressed isolated from the technical environment. On the other hand, technicians are prone to concentrate on the hardware. These conditions underline the need to pursue a more integrated evaluation and design procedure in order to avoid the drawbacks of t

The day-to-day variation in oxygen consumption ((V) over dot O-2) during ergometer cycling by 20 healthy adolescents, 10 females and 10 males, was measured using indirect calorimetry. The two sets of measurements were performed on two consecutive days. Great care was taken to minimize possible disturbing factors. Cycling started at 50 and 100 W for female and male adolescents, respectively. The lo

Here, we describe the preparation, structure, and properties of cryogel sponges, which represent a new type of macroporous biomaterial for tissue engineering. Cryogels were produced through freeze-thawing techniques, either from agarose alone or from agarose with grafted gelatin. The aim of this study was to evaluate agarose cryogel sponges as scaffolds for Culturing both isolated pancreatic islet

A magnetic particle-based immuno-supported liquid membrane assay (m-ISLMA) based on chemiluminescence detection of a horseradish peroxidase-labeled hapten tracer that allows sample cleanup, analyte enrichment, and detection in a single analysis unit has been developed. Antibodies were immobilized on magnetic beads, and their position in the acceptor was controlled by two alternating opposing elect

A drop of systemic blood pressure (BP) occurring shortly after individuals move from supine or seated position to upright posture with subsequent prompt spontaneous resolution is a common physiological occurrence in humans. If the induced hypotension is severe, lightheadedness or postural instability leading to falls and injury may occur. By consensus, a transient systolic BP drop >40 mmHg within

The complex constitutional relationship between Greenland and Denmark has had no clearer manifestation than the last decade’s juridical and political wranglings over the control for uranium. In the article, we argue that the quarrel between Nuuk and Copenhagen found in their diverging uranium policies can be seen as what we term a ’securitization controversy’. That is, a form of negotiating proces

An experimental study on the duration of load effects in a glued shear plate dowel joint was conducted. The joint design features a single large diameter dowel for load transfers between members, via external steel plates, which are bonded to the timber with a low stiffness bond line. Due to the low bond line stiffness, the timber element is subjected to a close to uniform shear stress distributio

Background: Limited data exist of tracking and changes in accelerometer-measured physical activity in children. Methods: Physical activity was assessed by accelerometers for 4 days in 167 children (boys, n = 90; girls n = 77) age 9.8 ± 0.6 years. Follow-up measurement was made 2.0 ± 0.1 yrs later (range 1.9-2.1 yrs). General physical activity (GPA) was defined as mean count/minute. Minutes of inac

Identification of prostate gold fiducial markers in magnetic resonance imaging (MRI) images is challenging when CT images are not available, due to misclassifications from intra-prostatic calcifications. It is also a time consuming task and automated identification methods have been suggested as an improvement for both objectives. Multi-echo gradient echo (MEGRE) images have been utilized for manu

On the 11th October 2016 the opposition Labour Party presented the ruling Conservative UK government with a list of 170 questions – one for each day before Theresa May’s self-imposed deadline to start the process of leaving the EU. A more realistic list of questions in the UK’s ‘Brexit’ debate right now would consist of 17 000 questions – the four decade-old UK-EU relationship raises so many quest
