Aims: The purpose of this study was to investigate criterion-related validity and test–retest repeatability of the heart rate monitor Polar RS400 versus electrocardiogram (ECG). Methodology: Ten healthy subjects, 19–34 years, performed a cycle ergometer test 5 min on each load (50, 100 and 150 W). Heart rate (HR) was measured with ECG and Polar RS400 and recorded digitally. After at least one hour
In this study, effects of a dust hole and its location on the flow structure, endwall heat transfer and friction factor in a U bend channel used for a gas turbine blade tip cooling are numerically studied. The dust hole is placed on the endwall of a U bend at different locations. The U bend channel without dust hole is considered as Baseline. The Reynolds number ranges from 50,000 to 440,000. Resu
In the present study, wild type and three mutants of pyranose 2-oxidase (PyOx-WT, PyOx-MT1, PyOx-MT2, PyOx-MT3), which showed improved properties for D-galactose oxidation, were investigated for their oxidising ability when immobilised on graphite electrodes. Four different flexible Os polymers with formal potentials ranging between −0.140 and 0.270 V vs. Ag|AgCl0.1 M KCl were applied together wit
Aim: To investigate an association between autoimmune disorders (AID) and hospitalization for dementia and Alzheimer's disease, and to study whether the risk is associated with follow-up time and age. Methods: We followed up all individuals in Sweden without previous hospital admission for dementia and Alzheimer's disease, and with a primary or secondary diagnosis of an AID between 1 January 1964
1. Five groups of male Sprague Dawley rats were given for 6 months a diet with high protein and fat contents but a very low dietary fibre content (group B), and this diet mixed with (g/kg) 50 low-methoxyl pectin (group L), 50 high-methoxyl pectin (group H), 50 guar gum (group G) and 200 wheat bran (group WB, corresponding to 100 wheat fibre) respectively. 2. The weight increment was significantly
The aim of our study was to examine the pathophysiology of ST depression (STD) in leads V1-V3 in the setting of inferior ST elevation myocardial infarction (iSTEMI) through the perspective of cardiac magnetic resonance (CMR). Methods: Differences in myocardial area at risk (MaR), infarct size, ejection fraction and myocardial segment involvement by CMR were compared in MITOCARE trial patients with
Objective To describe the experiences of people with systemic sclerosis (SSc) in different European countries of functioning and health and to link these experiences to the WHO International Classification of Functioning, Disability and Health (ICF) to develop a common understanding from a bio-psycho-social perspective. Method A qualitative multicentre study with focus-group interviews was perform
This thesis measures cost efficiency in the production of health care and social services in Sweden. The object of analysis is not provider efficiency, but instead the relative efficiency of political organizations or different contractual arrangements. The thesis focuses on: 1) the measurement of cost efficiency, 2) the investigation of potential trade-offs between quantity of health care service
The Italian Sarcoma Group and the Scandinavian Sarcoma Group designed a joint study to improve the prognosis for patients with Ewing's family tumors and synchronous metastatic disease limited to the lungs, or the pleura, or a single bone. The study was opened in 1999 and closed to the enrollment in 2008. The program consisted of intensive five-drug combination chemotherapy, surgery and/or radiothe
Laurdan (6-lauroyl-2-dimethylaminonaphthalene) fluorescence spectroscopy has been applied to probe the physical status of the thylakoid membrane upon conversion of violaxanthin to zeaxanthin. So far, only phospholipid-dominated membranes have been studied by this method and hereby we report the first use of laurdan in mono- and digalactosyldiacylglycerol-dominated membrane systems. The generalised
The REVEALS model was developed to reconstruct quantitatively regional vegetation abundance (in a 10(4)-10(5) km(2) area) from pollen assemblages in large lakes (>= 100-500 ha). This model corrects for biases in pollen percentages caused by inter-taxonomic differences in pollen productivity and dispersal. This paper presents the first case study to validate REVEALS, using empirical data from south
Objective: To explore the natural course of knee osteoarthritis (OA) in a middle-aged population with chronic knee pain. Methods: A population-based sample of 143 subjects (mean age 45 (range 35-54), 44% women) with knee pain (>3 months) at inclusion was studied. Weightbearing posteroanterior tibiofemoral (TF) radiographs were obtained at baseline and 12 years later, and classified according to Ke
To describe incidence, risk factors, and influence of treatment on occurrence of central nervous system (CNS) relapse or progression in younger patients with aggressive B-cell lymphoma. We analyzed 2210 patients with aggressive B-cell lymphoma treated on various studies for CNS relapse/progression. Treatment consisted of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) +/- etoposi
Increasing precipitation and surface water temperature due to global change may strengthen the salinity gradient in coastal regions, which could influence the behaviour of dinoflagellate migration. We studied diel vertical migration (DVM) behaviour in the dinoflagellates Prorocentrum minimum and Heterocapsa triquetra using vertically stratified laboratory columns with 3 different salinity gradient
The general view of learning has dramatically changed during the last two decades. Today we talk about learning for life and educate to meet the demands of the information society. This new view forces us to constantly relearn and develop new knowledge ? something which has resulted in large restructuring within the upper secondary school. New forms of teaching, where the pupils are given the oppo
This paper presents the outcomes of an applied cultural study carried out during spring semester 2010 with more than 10 Chinese female postgraduate students in Swedish universities. The aims of this research were to investigate Chinese female postgraduates’ decision-making process, to understand university lives in Sweden with the main focus on their learning experiences and social activities, and
Background: To explore the point prevalence of the risk of malnutrition and the targeting of nutritional interventions in relation to undernutrition risk and hospital volume. Methods: A cross-sectional survey performed in nine hospitals including 2 170 (82.8%) patients that agreed to participate. The hospitals were divided into large, middle, and small sized hospitals. Undernutrition risk and over
