Popular Abstract in Swedish Många forskningsprojekt inom materialvetenskap, medicin eller grundläggande fysik kräver smala strålar av laddade partiklar som fungerar som provtagare för att undersöka materiens egenskaper. Dessa partiklar kan vara protoner, elektroner lättare joner. Relativt ofta, behöver de accelereras nästan upp till ljusets hastighet för att kunna tränga in tillräckligt djupt i prLaser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the

This article analyzes Natan against the background of an increasingly mobile world where social relations and practices have become disembedded and social capital decreases. Natan outlines an inability to feel at home in modern society, and counters this experience by restoring a nostalgic home for a seemingly homeless man.

Objective: To examine the contents of the Mayo-Portland Adaptability Inventory (MPAI-4) by mapping it to the International Classification of Functioning, Disability and Health (ICF). Methods: Each of the 30 scoreable items in the MPAI-4 was mapped to the most precise ICF categories. Results: All 30 items could be mapped to components and categories in the ICF. A total of 88 meaningful concepts wer

Abstract in Undetermined How signal diversity evolves under stabilizing selection in a pheromone-based mate recognition system is a conundrum. Female moths produce two major types of sex pheromones, i.e., long-chain acetates, alcohols and aldehydes (Type I) and polyenic hydrocarbons and epoxides (Type II), along different biosynthetic pathways. Little is known on how male pheromone receptor (PR) gHow signal diversity evolves under stabilizing selection in a pheromone-based mate recognitionsystem is a conundrum.

Popular Abstract in Swedish Förmaksflimmer är den vanligaste rytmrubbningen i hjärtat. Man beräknar att 1-2% av befolkningen har förmaksflimmer. Förmaksflimmer blir vanligare med stigande ålder. Bland personer äldre än 75 år har 5-10% förmaksflimmer. Var fjärde person över 40 år riskerar att drabbas av förmaksflimmer någon gång i livet. Förmaksflimmer ger bl.a. en ökad risk för blodproppar och strAtrial fibrillation (AF) is the most common sustained cardiac arrhythmia in the general population, and a major cause of morbidity and mortality. Low-grade inflammation, erythrocyte volume variation, and subclinical atherosclerosis have repeatedly been associated with cardiovascular disease, but it remains unclear whether these risk factors are also associated with incident AF. This thesis is bas

The acceptable noise level (ANL) test is used to quantify the amount of competing background noise (BNL) that a listener is willing to accept when listening to speech at the most comfortable level (MCL). ANL is calculated by subtracting the BNL from the MCL. Most studies show large intersubject ANL variability and a few also demonstrate large intrasubject variability. Very few predictor variables

Purpose: To evaluate the dose distribution of a 120-MeV laser-plasma accelerated electron beam which may be of potential interest for high-energy electron radiation therapy. Methods: In the interaction between an intense laser pulse and a helium gas jet, a well collimated electron beam with very high energy is produced. A secondary laser beam is used to optically control and to tune the electron b

Background and Objectives Weak expression of A/B histo-blood group antigens is often explained by single nucleotide substitutions at the ABO locus. However, hybrid alleles containing segments from different ABO alleles can result in unexpected phenotypes and may complicate genotype analysis. We investigated the basis of weak B phenotype in a referred sample. Materials and Methods A healthy young w

Specialist plant species in calcareous sandy grasslands are threatened by acidification and high nutrient levels in the topsoil. We investigated whether topsoil removal and soil perturbation in degraded sandy grasslands could lead to establishment of specialist species belonging to the threatened xeric sand calcareous grassland habitat. Restoration actions performed in 2006 resulted in increased s

Preclinical studies in mice suggest that the natural killer cell receptor NKp46 may be a new molecular target for delaying the progression of type 1 diabetes by interfering with unexpected natural killer cell-mediated recognition of pancreatic beta cells.

Copolymeric NiPAM:BAM nanoparticles of varying hydrophobicity were found to retard fibrillation of the Alzheimer's disease-associated amyloid beta protein (A beta). We found that these nanoparticles affect mainly the nucleation step of A beta fibrillation. The elongation step is largely unaffected by the particles, and once the M is nucleated, the fibrillation process occurs with the same rate as

Purpose: Diagnosis of chronic atrophic fundal gastritis (CAFG) is important to understand the pathogenesis of gastric diseases and assess the risk of gastric cancer. Autofluorescence imaging videoendoscopy (AFI) may enable the detection of mucosal features not apparent by conventional white-light endoscopy. The purpose of this study was to estimate the diagnostic ability of AFI in CAFG. Methods: A

Background. A contralateral tumor occurs in 3.5-5% of men diagnosed with testicular germ cell cancer (TGCC). Biopsy of the contralateral testis may detect intratubular germ cell neoplasia ITGCNU, a precursor of TGCC. Biopsy of the contralateral testis to detect ITGCNU is controversial. If adjuvant chemotherapy (ACT) protects against bilateral cancer is debated. Material and methods. A total of 100

To identify prognostic factors after hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT). We retrospectively reviewed the combined experience at Toronto General Hospital and Hospital Vall d'Hebron managing HCC recurrence after LT (n = 121) between 2000 and 2012. We analyzed prognostic factors by uni- and multi-variate analysis. Median follow-up from LT was 29.5 (range 2-129.

The authors conducted 2 studies to evaluate whether emotional contagion, the propensity to automatically imitate the emotional expressions of others and experience the corresponding emotions, is related to behavioral and experiential indices of hypnotizability and whether such a relationship is influenced by administration context. In Study 1, behavioral and subjective measures of hypnotizability

OBJECTIVE - Interleukin (IL)-1 impairs insulin secretion and induces P-cell apoptosis. Pancreatic beta-cell IL-1 expression is increased and interleukin-1 receptor antagonist (IL-1Ra) expression reduced in patients with type 2 diabetes. Treatment with recombinant IL-1Ra improves glycemia and P-cell function and reduces inflammatory markers in patients with type 2 diabetes. Here we investigated the
