Background: The aim of this study was to examine in elderly men a relationship between depressive symptoms, peripheral vascular disease and cerebral blood flow (CBF). Methods: Population-based cohort study started with an examination of 809 men at age 55, followed by the first (age 68ys) and second follow up (age 82ys). 128 survivors were examined at age 82 with Tc-99m-HMPAO-SPECT to estimate CBF,

According to the Swedish Hernia Register (SHR), the reoperation rate is more than doubled after recurrent groin hernia repair compared with primary repair. The aim was to study the impact of type of mesh repair used in recurrent groin hernia surgery on a 2nd recurrence in a population-based cohort derived from the SHR. All 1st recurrent hernia repairs in the south-west region of Sweden, registered

Subjects: 118 type 2 diabetic patients with micro-macroalbuminuria were followed for four years (range 1-8 years). Method and main outcome measures: The prognostic significance of office, day- and nighttime measurements of blo

Measurements are presented from proton-proton collisions at centre-of-mass energies of root s = 0.9, 2.36 and 7 TeV recorded with the ATLAS detector at the LHC. Events were collected using a single-arm minimum-bias trigger. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity and the relationship between the mean transverse momentum and charged-particle multi

Objectives. To study the longitudinal development of pulmonary function in patients with primary SS (pSS) and its association with respiratory symptoms, pulmonary radiographic findings and clinical features of pSS.Methods. Forty-one pSS patients, previously evaluated by pulmonary function tests (PFTs), were included in the study. The patients were studied at baseline and follow-up by PFT and at fo

Abstract in French Cet article examine le rôle et la place des femmes dans les transactions financières d'Ancien Régime, en particulier dans les communautés rurales.

Cathodoluminescence (CL) imaging and spectroscopy are used to study one-dimensional structures from three different decades. Quantum-well wires were fabricated in the 1980s and CL images are presented here, where the individual wires of a 450 nm grating are resolved. V-grooved quantum wires (QWRs) were fabricated in the 1990s and the structures exhibit a number of emission peaks. CL is used to ide

The AuI atom in the title compound, [Au(C21H24N2)(2)](C24H20B5O6), adopts a slightly distorted linear AuC2 coordination geometry arising from its coordination by two mesitylenic N-heterocyclic carbene ligands, forming an overall cationic complex. The dihedral angle between the imidazole rings is 57.3 (6)degrees. In the crystal, the components are linked by weak C-H...O hydrogen bonds.

Objectives: The aim of this study was to investigate the influence of specific components of Andersen's behavioural model on adult individuals' perceived oral treatment need. Methods: A questionnaire was sent to a randomly selected sample of 9,690 individuals, 20 to 89 years old, living in Skane, Sweden. The 58 questions, some with follow-up questions, were answered by 6,123 individuals; a 63% res

Abstract in UndeterminedWe discuss the combination of a hybrid finite element approach and three-dimensional Voronoi-based mesh discretisations for electromechanically coupled problems. The fluxes, i.e. the stresses and electric displacements, are defined within the volume of the polygonal finite elements, whereas the displacements and electric potential are approximated on the boundaries of the e

Carbon deposition has a serious effect on the performance of solid oxide fuel cells (SOFCs). An unsteady-state 2D model based on COMSOL software is used to study the carbon deposition process in a planar SOFC. The carbon deposition, catalyst activity, reaction rate and temperature fields are obtained to analyse the mechanism of carbon deposition in the SOFC at different operating time. The effects

Galectins are carbohydrate binding proteins, implicated in conditions of both inflammation and cancer. Connections between chronic inflammation and cancer are proposed by the increased remodelling and proliferation that occurs, leading to enhanced survival and proliferation of malignant cells. Since galectins have been implicated in mechanisms of both chronic inflammation and cancer, we have inves

This thesis presents models and methods for feedback-based resource management for cyber-physical systems. Common for the scenarios considered are severe resource constraints, uncertain and time-varying conditions and the goal of enabling flexibility in systems design rather than restricting it. A brief survey on reservation-based scheduling, an important enabling technology for this thesis, is pr

Popular Abstract in Swedish Cancer är den ledande dödsorsaken i världen och stod för 7,6 miljoner dödsfall under 2008, vilket beräknas vara omkring 13 % av den totala dödsfallsiffran. Även om det finns flera olika metoder för att behandla eller bromsa cancerutveckling, krävs det nya terapier på grund av allvarliga biverkningar och otillfredsställande resultat med de nuvarande behandlingsmetoderna.Proteoglycans (PG) are highly anionic macromolecules consisting of a core protein covalently substituted with long unbranched polysaccharide chains called glycosaminoglycans (GAGs). PGs are central components in multicellular organisms, and they may occur in the extracellular matrix (ECM), at the cell surface, or in the secretory pathway. At the tumor cell surface, PGs and GAGs are involved in the

Unemployment swings have distributional consequences if some groups are hit harder than others. We examine if the sensitivity to local unemployment rates varies by characteristics such as health, cognitive ability and non-cognitive ability. Data on these variables come from registers covering the entire Swedish population of males. We show that variations in the unemployment rate are associated wi

Placodium umbrinum Breuss is reported as new to northern Europe from the island of Gotland, Sweden. The species is described and depicted, and its ecology at the locality on Gotland is given. A key is given for former members of the genus Catapyrenium growing on soil, mosses or bark in the Nordic countries.

Floor adhesives on cement-based substrates may degrade if the pH is high enough and this has in many cases led to emissions of odorous substances and deteriorated indoor air quality. We have used isothermal calorimetry to assess the degradation rate of two floor adhesives as a function of pH. The rate of heat production measured by the calorimeter is proportional to the reaction rate. The degradat

A simple and easy-to-use extraction method for aqueous samples based on hollow fibre-supported liquid membrane (HF-SLM) followed by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) was developed to determine ivermectin and transformation products, the monosaccharide (TP1) and the aglycon of ivermectin (TP2). The proposed method attained enrichment factors up to 80, after optimi

Popular Abstract in English In the modern world of today, we are surrounded with many electronic devices which offer previously unseen performance. These devices constitute a large part of the everyday consumer electronics such as laptops, tablets, smart phones, etc., but are also used in wide variety of domains such as automotive industry, avionics, medicine, etc. The constant demand for high perIncreasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. The time overhead is particularly important for a group of computer systems referred to as real-time systems (RTSs) where correct operation is defined as producing the correct re

Abstract in UndeterminedIt has recently been argued that giving is spontaneous while greed is calculated (Rand et al. 2012). If greed is calculated we would expect that cognitive load, which is assumed to reduce the influence of cognitive processes, should affect greed. In this paper we study both charitable giving and the behavior of dictators under high and low cognitive load, to test if greed i
