Purpose: To propose a new simplified technique to occlude multiple segmental arteries for staging and preconditioning of the spinal cord to decrease the potential for spinal cord ischemia after thoracic and thoracoabdominal aortic aneurysm repair. Technique: A thoracic stent-graft that flares out to a maximum of 51 mm is deployed in a standard fashion covering all segmental arteries where graft-wa

We show first results for the elastic scattering of neutrons off oxygen and calcium isotopes obtained from ab initio optical potentials. The potential is derived using self-consistent Green's function theory (SCGF) with the saturating chiral interaction NNLOsat. Calculations are compared to available scattering data and show that it is possible to reproduce low energy scattering observables in med

It is not physically obvious why one can calculate with similar accuracy, as compared to the experimental data, the absolute cross section associated with two-nucleon transfer processes between members of pairing rotational bands, making use of simple BCS (constant matrix elements) or of many-body [Nambu-Gorkov (NG), nuclear field theory (NFT)] spectroscopic amplitudes. Restoration of spontaneous

In Landau theory of Fermi liquids, the particle-hole interaction near the Fermi energy in different spin-isospin channels is probed in terms of an expansion over the Legendre polynomials. This provides a useful and efficient way to constrain properties of nuclear energy density functionals in symmetric nuclear matter and finite nuclei. In this study, we present general expressions for Landau param

We propose to use two-body regularized finite-range pseudopotential to generate nuclear energy density functional (EDF) in both particle-hole and particle-particle channels, which makes it free from self-interaction and self-pairing, and also free from singularities when used beyond mean field. We derive a sequence of pseudopotentials regularized up to next-to-leading order and next-to-next-to-lea

Background: Older adults with pain have an increased risk of falling (odds ratio (OR) 1,7). Pain in Parkinson’s disease (PD) is more common than in older adults. The association between pain and falling in people with PD is poorly explored.Objective: To investigate the occurrence of pain in mild PD and its association with future falls/near fallsMethods.

Background: The complement and kallikrein-kinin systems (KKS) are activated during vascular inflammation. The aim of this study was to investigate if blockade of the KKS can affect complement activation on the endothelium during inflammation. Methods: Complement deposition on endothelial microvesicles was assayed in vasculitis patient plasma samples and controls. Plasma was perfused over glomerula

Background: Individuals born with low birth weight (LBW) have an increased risk of metabolic diseases when exposed to diets rich in calories and fat but may respond to fasting in a metabolically preferential manner. We hypothesized that impaired foetal growth is associated with differential regulation of gene expression and epigenetics in metabolic tissues in response to fasting in young adulthood

As it has been shown in a number of reports, extremely-low- frequency (ELF) electromagnetic field (EMF) can induce different changes in various biological systems, even if its intensity is comparable to the level of thermal noise. According to the parameters of generated field variable results have been obtained, including these regarding cell proliferation. Simultaneously it has also been demonst

Ammonia (NH3) has been identified as a potential hydrogen-carrier fuel with no carbon emissions. Non-intrusive in-situ NH3 diagnostic technique is of great interest. In this work, femtosecond two-photon laser-induced fluorescence (fs-TPLIF) was demonstrated in NH3/N2 mixtures to achieve NH3 measurements. A femtosecond laser at 305 nm was used for two-photon excitation of NH3 to its excited state (

Delegationen för senior arbetskraft har i uppdrag att verka för ett mer inkluderande och åldersoberoende synsätt i arbetslivet. Delegationen ska sammanställa och sprida kunskap om forskning om äldres möjligheter och även föreslå åtgärder som motverkar åldersdiskriminering för att bättre tillvarata senior erfarenhet. Som en viktig del av arbetet med uppdraget har delegationen valt att ta fram en se

Introduction: Breathlessness is common in the population, especially in women and associated with adverse health outcomes. Obesity (body mass index (BMI) >30 kg/m2) is rapidly increasing globally and its impact on breathlessness is unclear. Methods: This population-based study aimed primarily to evaluate the association of current BMI and self-reported change in BMI since age 20 with breathlessnes

We present the first comprehensive, long run salary information on Swedish middle-class employees before the twentieth century. Our data include, for instance, school teachers, professors, clerks, policemen and janitors in Stockholm and Sweden, ca. 1830–1940. We use the new data to compare the annual earnings of these middle-class employees with the annual earnings of farm workers, unskilled const

Given the increasingly polarized debates in many modern democracies over migration and integration, the behaviour of members of parliament (MPs) with a migrant background has important implications for patterns of representation. Drawing on role congruity theory, we hypothesize that MPs with a migrant background deliver more legislative speeches in debates that are of interest for citizens with a

Different types of white bread are sold and widely consumed worldwide. The objective of this study was to evaluate the starch digestibility in the crust of different white breads. Three popular commercial white breads were analyzed for dietary fiber (DF), thermal properties, texture, starch hydrolysis and resistant starch (RS) contents, in freshly baked and stored samples. The DF content in fresh

Crustacean copepods in high-latitude lakes frequently alter their pigmentation facultatively to defend themselves against prevailing threats, such as solar ultraviolet radiation (UVR) and visually oriented predators. Strong seasonality in those environments promotes phenotypic plasticity. To date, no one has investigated whether low-latitude copepods, experiencing continuous stress from UVR and pr

Research has dealt extensively with different aspects of climate change and winter tourism such as the impact on ski resorts and ski lift operators, adaptation strategies, governance at destinations and reactions of winter sports guests to changing snow conditions. This paper goes deeper into the question of destination choice and examines the role of climate change among the many factors affectin
