An investigation regarding the design of a safe refuge area and more specifically the means for communication from the safe refuge areawas performed. Three types of communication techniques were tested using a survey and using experiments in a virtual reality environment; a signal lamp in combination with a push button system, a text display system and finally a voice communication system. Accordi

PurposeThe purpose of this paper is to identify and analyze the professional norms surrounding school development, with a special emphasis on school principals’ pedagogical leadership.Design/methodology/approachA norm perspective is used to identify possible links between legal norms, professional norms, and actions. The findings are based on answers given by 974 school principals in a web-based q

White matter lesions (WMLs) are a common finding in patients with dementia. This study investigates the relationship between WMLs, hyperphosphorylated tau (P-tau) in cerebrospinal fluid (CSF) and apolipoprotein E (APOE) ε4 genotype in prodromal Alzheimer's disease (AD).

Context: Distributed teams characterize Global Software Engineering (GSE). GSE stakeholders are from different cultures, geographic places and potentially time zones. These conditions have significant consequences on communication, coordination and control of software projects. Given these constraints, distributed teams need to highly rely on each other. Trust is the glue that holds them together

Context. It is debated whether the Milky Way bulge has characteristics more similar to those of a classical bulge than those of a pseudobulge. Detailed abundance studies of bulge stars are important when investigating the origin, history, and classification of the bulge. These studies provide constraints on the star-formation history, initial mass function, and differences between stellar populati

Context: Extracellular nucleotide receptors are expressed in pancreatic B-cells. Purinergic signaling via these receptors may regulate pancreatic B-cell function. Objective: We hypothesized that purinergic signaling might influence glucose regulation and sought evidence in human studies of glycemic variation and a mouse model of purinergic signaling dysfunction. Design: In humans, we mined genome-

Cold sensitivity is a common and persistent complaint after various hand injuries and diseases. The general aim of the thesis was to investigate the consequences of cold sensitivity for daily life in patients with traumatic hand injuries and hand-arm vibration syndrome (HAVS). To obtain a richer and more comprehensive picture reflecting the aim, studies with a quantitative and a qualitative design

Background. Methylmalonic acid (MMA), a sensitive biomarker of functional vitamin B12 deficiency, is commonly determined by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods using manual extraction and derivatization of MMA to reduce polarity prior to separation. Methods. In the present study we introduce a semi-automated extraction o

Background Long-term outcome after hematopoietic stem cell transplantation including late transplant-related events is of increasing interest. The aim of this study was to evaluate the incidence of cardiovascular events after allogeneic HSCT and to search for their risk factors. Design and Methods This is a retrospective mutlicenter European Group of Blood and Marrow Transplantation (EBMT) analysi

The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people were

We present a study of solvent effects on the zero-point vibrational corrections (ZPVC) to optical rotations and nuclear magnetic resonance shielding constants of solvated molecules. The model used to calculate vibrational corrections rely on an expansion of the potential and property surfaces around an effective molecular geometry and includes both harmonic and anharmonic correction. Numerical exa

We report the signature of an unconventional zwitterion in thick (>40 angstrom) L-cysteine films grown at low temperature (100 K) by means of sublimation in ultrahigh vacuum. Using X-ray photoelectron spectroscopy (XPS) we find that protonated amino groups (57%) are less prevalent than in films grown at higher temperatures. A large majority of the protonated amino groups receive the hydrogen throu

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

Objectives: What is the prognostic significance of achieving a systolic blood pressure of

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
