Psychometric properties of the disease-specific health-related quality of life instrument VascuQoL in a Swedish setting

Background: Traditional outcome measures in peripheral arterial disease (PAD) provide insufficient information regarding patient benefit. It has therefore been suggested to add patient-reported outcome measures. The main aim of this study was to validate the Swedish Vascular Quality of Life questionnaire (VascuQoL) version, a patient-reported PAD-specific health-related quality of life (HRQoL) ins

Genetic algorithm approach for QoS-based tree topology construction in IEEE 802.16 mesh networks

The topological characteristics of an IEEE 802.16 mesh network including the tree’s depth and degree of its nodes affect the delay and throughput of the network. To reach the desired trade-off between delay and throughput, all potential trees should be explored to obtain a tree with the proper topology. Since the number of extractable tree topologies from a given network graph is enormous, we use

Laos in 2009. Recession and Southeast Asian Games

Laos in 2009 was colored by the Southeast Asian Games held in December, and by the effects of the global financial crisis. Growth rates declined as foreign investment, primarily in hydroelectric power and infrastructure, was postponed. Simultaneously, efforts were made to strengthen the reputation of the country internationally.

Making Food Protein Gels via an Arrested Spinodal Decomposition

We report an investigation of the structural and dynamic properties of mixtures of food colloid casein micelles and low molecular weight poly(ethylene oxide). A combination of visual observations, confocal laser scanning microscopy, diffusing wave spectroscopy, and oscillatory shear rheometry is used to characterize the state diagram of the mixtures and describe the structural and dynamic properti

Prediction of Postoperative Pain After Mandibular Third Molar Surgery

Aims: To evaluate the predictive potential of preoperative psychological and psychophysiological variables in estimating severity of postoperative pain following mandibular third molar surgery (MTMS). Methods: Following ethical committee approval and informed consent, 40 consecutive patients scheduled for MTMS were included. Preoperative psychometric indicators of anxiety, depression, and vulnerab

Preventable breast cancer is postmenopausal

Breast cancer incidence has markedly increased in Western countries for reasons that are not entirely understood. We characterized periodic and age-specific incidence trends of breast cancer in immigrants who migrated from low incidence areas to Sweden. The incidence in immigrants was compared to that in native Swedes and standardized incidence ratios (SIRs) were calculated, based on the Swedish F

Latitudinal-Related Variation in Wintering Population Trends of Greylag Geese (Anser Anser) along the Atlantic Flyway: A Response to Climate Change?

The unusually high quality of census data for large waterbirds in Europe facilitates the study of how population change varies across a broad geographical range and relates to global change. The wintering population of the greylag goose Anser anser in the Atlantic flyway spanning between Sweden and Spain has increased from 120 000 to 610 000 individuals over the past three decades, and expanded it

Metabolic Syndrome and Breast Cancer in the Me-Can (Metabolic Syndrome and Cancer) Project

Background: Few studies have assessed the metabolic syndrome (MetS) as an entity in relation to breast cancer risk, and results have been inconsistent. We aimed to examine the association between MetS factors (individually and combined) and risk of breast cancer incidence and mortality. Methods: Two hundred ninety thousand women from Austria, Norway, and Sweden were enrolled during 1974-2005, with

High-resolution regional simulation of last glacial maximum climate in Europe

A fully coupled atmosphere-ocean general circulation model is used to simulate climate conditions during the last glacial maximum (LGM). Forcing conditions include astronomical parameters, greenhouse gases, ice sheets and vegetation. A 50-yr period of the global simulation is dynamically downscaled to 50 km horizontal resolution over Europe with a regional climate model (RCM). A dynamic vegetation

Historical aspects of soil erosion in the Mejerda catchment, Tunisia

Agricultural use and related water erosion leads to significant changes in the sedimentological and hydrological characteristics of watersheds and thus means negative consequences for rural development. This research work aimed at putting present-day soil erosion of the important Mejerda catchment in to a historical context. The catchment of wadi Mejerda in northern Tunisia has experienced soil er

Kartläggning av svensk FoU inom området IT och miljö

Swedish R&D activities in the field of IT and the environment - a mapping related to indirect environmental effects and effects at system level Feb 2009: Peter Arnfalk, Andrius Plepys, Chris van Rossem, The International Institute for Industrial Environmental Economics, Lund University. The International Institute for Industrial Environmental Economics (IIIEE) at Lund University has, in autumn

Prenylhydroxybenzoic acid compounds with pungent activity from Piper arieianum (CDC) leaves

Prenylhydroxybenzoic acid derivatives and other two analogues previously reported were isolated from Piper arieianum leaves. The structures of the compounds were assigned from detailed spectroscopical analysis (NMR 1D and 2D and HR ESI TOF MS) data and by comparison with data from the literature. These molecules posses pungent activity different to that of capsaicin and their activity is related t

Mid-Thigh Cortical Bone Structural Parameters, Muscle Mass and Strength, and Association with Lower Limb Fractures in Older Men and Women (AGES-Reykjavik Study)

In a cross-sectional study we investigated the relationship between muscle and bone parameters in the mid-thigh in older people using data from a single axial computed tomographic section through the mid-thigh. Additionally, we studied the association of these variables with incident low-trauma lower limb fractures. A total of 3,762 older individuals (1,838 men and 1,924 women), aged 66-96 years,

The mode of school transportation in pre-pubertal children does not influence the accrual of bone mineral or the gain in bone size - two year prospective data from the paediatric osteoporosis preventive (POP) study

Background: Walking and cycling to school are one source of regular physical activity. The aim of this two years observational study in pre-pubertal children was to evaluate if walking and cycling to school was associated with higher total amount of physical activity and larger gain in bone mineral content (BMC) and bone width than when going by car or bus. Methods: 133 boys and 99 girls aged 7-9
