We investigated effects of concurrent cognitive task difficulty (n-back) on the regularity of whole-body movements during treadmill walking in women and men from 3 age groups (20-30, 60-70, and 70-80 years old). Using principal component analysis of individual gait patterns, we separated main (regular) from residual (irregular) components of whole-body motion. Proportion of residual variance (RV)

The diagnostic workup in dementia includes brain imaging with reading focussed on signs of cerebrovascular and neurodegenerative disease. We hypothesised that these findings may be underreported in hospital patients, where imaging is often performed to rule out obvious pathology such as haemorrhage. In this study, we review cranial computed tomography (CT) in medical inpatients for white matter ch

This paper presents a study of the performance of the muon reconstruction in the analysis of proton-proton collisions at root s = 7TeV at the LHC, recorded by the ATLAS detector in 2010. This performance is described in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons. The results are obtained from an analysis of J/psi meson a

The buoyancy of fruits (nutlets in utricles) of the marsh-inhabiting True Fox Sedge (Carex vulpina) was tested experimentally in stagnant water. Only 16 % of the seeds had sunk when the experiment was terminated after 284 days. Seeds did not germinate while floating, but remained fully viable (average 76 % germination for both floating and sunken seeds). For comparison, fruits of the grassland spe

Background: The aim of this longitudinal study was to analyze whether mean Body Mass Index (BMI), assessed at four occasions, changed within different age groups and birth cohorts over time, i.e., between 1980/81 and 2004/05, after adjustment for possible confounders. Methods: A sample of 2728 men and 2770 women aged 16-71 years at study start were randomly drawn from the Swedish Total Population

Objective: The objective was to investigate the association between experience of violation during the past 3 months and self-rated health, taking trust (social capital), economic stress, and country of birth and parents' country of birth into account. Design/setting/participants/measurements: The 2008 public health survey in Skåne is a cross-sectional study with 55% response rate. A random sample

First predictions for specific case of the particle-hole-core coupling model which takes advantage of symmetries of a triaxial rotor with gamma = 90 degrees are reviewed. Results of the model calculations point towards existence of stable chiral geometry in specific configurations involving high-j orbitals. Next, experimental information on doublet bands built on unique parity, pi(h)11/2(Vh)11/2 i

This paper investigates the distribution of embedded verb second in Faroese, Icelandic, Norwegian, and Swedish. Two conclusions can be drawn from the study. First, none of the Scandinavian languages can be said to display generalized embedded verb second across the board. There are varieties of Faroese and Icelandic that display restrictions of the kind found in the other Scandinavian languages. I

The title compound, [Ni2(C22H46P2O2)2(CO)2], is located about a centre of inversion with the Ni(0) atom within a distorted trigonal-planar geometry. The cyclo-hexyl rings are in the usual chair conformation with the 1,3-cis substituents equatorially oriented. No specific inter-molecular inter-actions are noted in the crystal packing. A region of disordered electron density, most probably a disorde

We used a nested PCR protocol to examine the genetic diversity of cytochrome b (cyt b) lineages from blood parasites of the genera Plasmodium and Haemoproteus in birds in Bulgaria. In total, 460 birds of 43 species and 14 families (mostly passerines) were examined for the presence of infections. Of them, 267 were recognised as infected with haemosporidian parasites. Mixed infections were recorded

Background: Environmental barriers are associated with disability-related outcomes in older people but little is known of the effect of environmental barriers on mortality. The aim of this study was to examine whether objectively measured barriers in the outdoor, entrance and indoor environments are associated with mortality among community-dwelling 80- to 89-year-old single-living people. Methods

This dissertation explores the nexus between sustainable tourism development and corporate social responsibility (CSR). It addresses the scope for CSR to promote sustainable tourism in an international development context. This objective was pursued by exploring three sub-questions: what tools have been used to stimulate social responsibility in tourism; how has ecotourism influenced social respon

Background: Overdiagnosis and subsequent overtreatment are important side effects of screening for, and early detection of, prostate cancer (PCa). Active surveillance (AS) is of growing interest as an alternative to radical treatment of low-risk PCa. Objective: To update our experience in the largest worldwide prospective AS cohort. Design, setting, and participants: Eligible patients had clinical
