Temperaturändringar och krympning påverkar betongkonstruktioners volym, och i konstruktioner som hindras från av röra sig kan sådana volymändringar leda till så kallade tvångseffekter, som i sin tur kan orsaka sprickbildning. När detta sker kan emellertid konstruktionen deformeras till viss del, vilket gör att tvångsspänningarna och därmed också sprickvidderna minskar. Uppsprickningsförloppet är sThermal actions and shrinkage cause volume changes in concrete structures. In structures which are restrained from movements, the restraint effects can cause cracking. However, when cracking occurs, the structure can deform to some extent, which reduces the restraint stresses and thus also the crack widths. As the exact crack development is hard to predict beforehand, the actual restraint and thus

Insulin and C-peptide responses to 0.5 g kg-1 intravenous glucose and 1.0 mg glucagon were studied in 34 healthy subjects (age 19-78 years, mean 45). Fasting blood glucose (r=0.59; p<0.001) and glycosylated haemoglobin (r=0.61; p<0.001) increased with age, but not the initial C-peptide and insulin responses to the glucose infusion. However, the C-peptide response at 70 min (r=0.36; p<0.05), 80 min

Carrot psyllids (Trioza apicalis) pose a constant threat to carrot production in parts of Europe, and treatments with chemical insecticides are common. To be able to develop alternative control tactics, more knowledge about the psyllid's host-finding behaviour and underlying physiology is needed. Using single-sensillum recordings from overwintered and non-overwintered males and females, we found e

Incorrect analysis results that are close to expected might not be recognized in scientific studies or routine patient care. In two field studies we obtained unexpected results in a large number of samples. The present study aimed to identify the source of error in the samples from these studies and to validate a method to obtain correct results. Pre-analytical procedures were scrutinized, giving

Health care professionals frequently describe performance management and monitoring of efficiency and quality measures for external accountability as an administrative burden with limited benefits. Professionals argue that they are subject to too tight control that signals distrust, limits professional autonomy and ultimately decreases their motivation to perform. At worst, poorly incen

INTRODUCTION: Falls in older aged adults are an important public health problem. Insight into differences in fall-related injury rates between countries can serve as important input for identifying and evaluating prevention strategies. The objectives of this study were to compare Global Burden of Disease (GBD) 2017 estimates on incidence, mortality and disability-adjusted life years (DALYs) due to

East African landscapes today are the result of the cumulative effects of climate and land-use change over millennial timescales. In this review, we compile archaeological and palaeoenvironmental data from East Africa to document land-cover change, and environmental, subsistence and land-use transitions, over the past 6000 years. Throughout East Africa there have been a series of relatively rapid

We present for the first time two-dimensional resonant inelastic x-ray scattering (RIXS) maps of multilayer and monolayer bi-isonicotinic acid adsorbed on the rutile TiO2(110) single crystal surface. This enables the elastic channel to be followed over the lowest unoccupied molecular orbitals resonantly excited at the N 1s absorption edge. The data also reveal ultra-fast intramolecular vibronic co

This volume presents cutting-edge research on integration and adaptation processes of second-generation immigrant adolescents in Spain that no doubt constitutes an important and timely contribution to the migration-integration debate. Principal findings of the Investigación Longitudinal de la Segunda Generación study indicate a comparatively smooth integration of second-generation immigrant adoles

Objective: The aim of the study was to describe patients’ experience of yoga as a treatment for hypertension, as well as their experience of living with hypertension. Design: Qualitative interview study Method and materials: In 2013–2014, in southern Sweden, patients with hypertension from three health care centres were invited to participate in a randomised controlled trial on yoga for hypertensi

We determine Mg abundances in six Gaia benchmark stars using theoretical one-dimensional (1D) hydrostatic model atmospheres, as well as temporally and spatially averaged three-dimensional (〈3D〉) model atmospheres. The stars cover a range of Teff from 4700 to 6500 K, log g from 1.6 to 4.4 dex, and [Fe H] from -3.0 dex to solar. Spectrum synthesis calculations are performed in local thermodynamic eq

Computational fluid dynamics (CFD) has been applied extensively for studying rotor-stator mixers (RSM) in the past, both as a design-tool and in modelling mixing and emulsification. Modelling is always a balance between accuracy and computational cost. The theoretically soundest methods (i.e. fully resolved transient simulations) have often been deemed unfeasible, and the majority of previously pu

We investigate whether sex differences in academic strengths have an impact on society by affecting the career choices made by women and men. By longitudinally following 167,776 individuals from Sweden, we found that (1) more 16-year old girls than boys had a relative strength in verbal/language school subjects than in technical/numerical ones, whereas more boys than girls had a relative strength

Polycrystalline Cubic Boron Nitride (PCBN) has been considered as the main cutting tool material for hard turning, which has the comparable surface finish quality as grinding, and high efficiency, economical technology in production. It is well known that the abrasiveness of the workpiece have the very important role of the machinability of the materials. Therefore, the tool wear of the PCBN inser

This paper addresses a road transport policy of allowing high capacity vehicles (HCVs) on the roads. The purpose is to examine the effect reduced road transport costs from HCVs can have on a modal shift. Two studies of HCV implementation in Sweden were combined. A micro-based case study modelled the distribution network of a major retailer in scenarios based on actual cost and flow data. A macro a

We recommend prophylaxis in haemophilic children with an inhibitor as a way of preventing the musculoskeletal impairment that is likely to affect them. This approach has been used for children without inhibitors with excellent results. If prophylaxis is not feasible, we suggest that intensive on-demand treatment should be given. Two agents, recombinant activated FVII (rFVIIa) and activated prothro

Lysine acetylation occurs in many protein targets, including core histones, transcription factors, and other proteins. Metastasis-associated protein 1 (MTA1) is implicated in the progression and metastasis of various epithelial tumors. Because MTA1 functions as a transcriptional coregulator, much of its role in cancer promoting processes are likely to involve its ability to regulate the transcript
