Exponential integrators are becoming increasingly popular for stiff problems of high dimension due to their attractive property of solving the linear part of the system exactly and hence being A-stable. In practice, however, exponential integrators are implemented using approximation techniques to matrix-vector products involving functions of the matrix exponential (the so-called ϕ-functions) to m

This article considers the influence of cutting data on burr formation when machining oxygen-free copper in a longitudinal turning operation. Burr formation and side-flow frequently occur in a cutting process, resulting in highly undesirable poor surface integrity and reduced dimensional accuracy of the machined components. Finite Element (FE) simulations of a cutting process were used to simulate

An analysis on selecting cutting speed, cutting feed and depth of cut when collecting data for the Colding Tool Life Model based on Woxen's Equivalent Chip Thickness was performed to achieve the lowest possible model error. All possible combinations of a large data set were evaluated with regard to model error. This work shows that an increase of ratio between the highest and lowest cutting speed,

Eyewitness statements are commonly used in the criminal justice system and viewed as having a high-probative value, especially when the witness has no motive to lie, other witness recollection corroborates the account, or the witness is highly confident. A fatal police shooting incident in Sweden had 13 witnesses (nine civilians and four police officers) and was also filmed with two mobile phones.

Background: Depression is among the major causes of disability with a negative impact on both daily life and work performance. Whilst depression is the primary cause of sick-leave and unemployment in today's workplace there is a lack of knowledge of the needs of individuals with depression regarding their return-to-work (RTW) process. Objective: To explore which factors are of critical importance

We performed genome-wide association studies and found single nucleotide polymorphisms (SNPs) at seven independent loci associated with prostate-cancer-specific survival time. Two SNPs replicated in an independent cohort. The SNP rs73055188 at AOX1 is associated with AOX1 gene expression level, which is correlated with biochemical recurrence.

Recent investigations have shown that deep eutectic solvents provide a suitable environment for self-organisation of biomolecules, in particular phospholipids and proteins. However, the solvation of complex lyophilic moieties by deep eutectic solvents still remains unclear. Here we explore the behaviour of zwitterionic surfactants in choline chloride:glycerol eutectic mixture. Dodecyl-2-(trimethyl

This chapter explores the Nordic countries’ attempts to reconcile their environmental front-runner ambitions with their high productivity as advanced welfare states. On the one hand, the Nordics have taken leading positions in promoting environmental issues on the international stage. On the other hand, however, their high productivity, which is needed to support their welfare aspirations, has mad

In order to investigate new materials for metal cutting applications, cubic boron nitride, cutting tools with different amounts of binder phase were sintered in HPHT toroid type apparatus under 7.7 GPa and in temperature range of 1450-2450°C. Initial mixtures of three composition were chosen with 50, 60, 65 vol. % of cBN, 5 vol. % of Al was added to mixture to prevent oxidation. Phase composition,

Ecological differences between the sexes are often interpreted as evidence of within-species ecological character displacement (ECD), a hypothesis with almost no direct tests. Here, we experimentally test two predictions that are direct corollaries of ECD between the sexes, in a salamander. First, we find support for the prediction that each sex has a growth rate advantage in the aquatic microhabi

Avhandlingen undersöker olika faktorer som påverkar livsvillkoren för unga svenskar med invandrarbakgrund. Genom att undersöka hur ungdomar föreställer sig sin framtid och vägen dit syftar studien till att ge insikt i hur ungdomar ser på sina livsmöjligheter. Avhandlingen diskuterar hur individer genom sina sociala nätverk (socialt kapital) och medverkan i olika kulturella aktiviteter (kulturellt The dissertation examines the determinants of life chances among young people with immigrant background in Sweden. The dissertation includes four research papers, each examining a specific research question on a determinant of life chances. The studies are based on datasets from two surveys: the Social Capital and Labour Market Integration survey, and a longitudinal study of ten schools in Malmö.S

Nonelderly hip fracture patients have gathered little scientific attention, and our understanding of the group may be biased by patient case-mix and lack of follow-up. Preconceptions may thwart adequate investigation of bone health and other comorbidities. This literature review focusses on who these patients between 20 and 60 years are, how to treat them and how to evaluate the outcome. 2–11% of

Structural characterization of glycosaminoglycans remains a challenge but is essential for determining structure-function relationships between glycosaminoglycans and the biomolecules with which they interact and for gaining insight into the biosynthesis of glycosaminoglycans. We have recently reported that xyloside-primed chondroitin/dermatan sulfate derived from a human breast carcinoma cell lin

This study evaluated the safety and tolerability of ocular RS1 adeno-associated virus (AAV8-RS1) gene augmentation therapy to the retina of participants with X-linked retinoschisis (XLRS). XLRS is a monogenic trait affecting only males, caused by mutations in the RS1 gene. Retinoschisin protein is secreted principally in the outer retina, and its absence results in retinal cavities, synaptic dysfu

Aim: The impact of BL11282, an imidazoline receptor (NISCH) agonist, on potentiation of glucose-stimulated insulin secretion (GSIS) from isolated human non-diabetic (ND) and type 2 diabetic (T2D) islets was investigated. Methods: Analysis of mRNA was performed by RNA-sequencing and qPCR. Insulin and cAMP by RIA and ELISA respectively. Results: RNA-sequencing data revealed that NISCH is highly expr

The application of conventional organic solvents has been essential in several steps of bioprocesses in order to achieve sufficient economic efficiency. The use of organic solvents is frequently used either to partly or fully replace water in the reaction medium or as a process aid for downstream separation. Nowadays, manufacturers are increasingly requested to avoid and substitute solvents with h

Hur kan man minska onödig detaljstyrning och formalism och öka handlingsutrymmet för medarbetare och första linjens chefer i offentligt finansierad verksamhet? I denna antologi föreslås ett ramverk som utvecklar befintlig forskning och har ambitionen att förklara hur tillitsbaserad styrning och ledning kan förstås och översättas till en fungerande praktik. Boken rymmer fem konceptuella kapitel och
