This questionnaire survey was initiated to acquire information for prepration of a series of field studies. The paper deals with questions that were related to the thermal responses of the feet and footwear performance. The questionnaire was sent to a harbour, a telecommunication company and a customs office. At the harbour most of the workers used footwear with warm lining during winter. Half of
Background: Serum creatinine-based estimates of GFR may be inaccurate in the elderly and there is need for improvement. Serum Cystatin C, not being influenced by muscle volume, may be more accurate. Material and methods: GFR was measured with plasma clearance of iohexol in 50 elderly persons aged >70 years. Blood tests were drawn for analysis of creatinine, albumin and urea. Cystatin C was analyse
The calculation of absorbed dose from internally incorporated radionuclides is based on the so-called specific absorbed fractions (SAFs) which represent the fraction of energy emitted in a given source region that is absorbed per unit mass in a specific target organ. Until recently, photon SAFs were calculated using MIRD-type mathematical phantoms. For electrons, the energy released was assumed to
Since 2007, Intelligent Energy (IE) has been involved in developing technologies and services in the hydrogen generation space with E.ON Gas Sverige AB and Swedish Gas Centre. The aim of this work is to support the development of a high-profile demonstration of hydrogen generation technologies in a Swedish context. The overall objective of the demonstration is to deploy a reforming based hydrogen
The effects of continuous and intermittent inhalation of perchloroethylene (PCE) on plasma butyrylcholinesterase (BuChE) activity, organ weights, liver morphology and motor activity in mice (strain NMRI) were tested. PCE exposure increased plasma BuChE activity in a time- and concentration dependent manner in both sexes. The increase was statistically significant at 37 p.p.m. in animals continuous
Popular Abstract in Swedish I denna avhandling har användbarheten av Virtual Reality (VR) utvecklats och undersökts för två användningsområden: participatorisk design av arbetsplatser och hjärnskaderehabilitering. Inom det första användningsområdet används VR tillsammans med fullskalemodellering, drama och demokratisk mötesteknik i en Visualiseringsverkstad. Denna arbetsmetod har utvecklats och tIn this thesis, the usability of Virtual Reality (VR) has been investigated and developed within two applications: participatory design of workplaces and brain injury rehabilitation. In the first application, VR is used in combination with full scale modelling, drama and democratic meetings in an Envisionment Workshop. This workshop has been developed and tested through several real workplace int
Chronic obstructive pulmonary disease (CCPD) is a disease primarily caused by cigarette smoking, which in turn has been shown to affect the susceptibility to and progression of airway infections. The question addressed in this study was how components from cigarette smoke could affect the defence mechanisms of T-cells and epithelial cells, and thereby contribute to the development of the COPD path
Background: Periodontal research has traditionally focused on the site level, regarding etiology, pathogenesis, and treatment outcome. Recently, some studies have indicated that the presence of periodontal disease is associated with reduced quality of life. The aim of this study is to investigate the impact of periodontal disease experience on the quality of life. Methods: This cross-sectional stu
Specific absorbed fractions (SAFs) have been calculated as a function of the content in the urinary bladder in order to allow more realistic calculations of the absorbed dose to the bladder wall. The SAFs were calculated using the urinary bladder anatomy from the ICRP male and female adult reference computational phantoms. The urinary bladder and its content were approximated by a sphere with a wa
There is an ever-increasing awareness and interest within the clinical research field that has creating a large demand for blood fraction samples as well as other clinical samples. The translational research area is another field that demanding for blood samples, used widely in proteomics, genomics, as well as metabolomics. Blood samples are the global most common biological samples that find its
We describe the implementation of a biochemical model of isoprene emission that depends on the electron requirement for isoprene synthesis into the Farquhar-Ball-Berry leaf model of photosynthesis and stomatal conductance that is embedded within a global chemistry-climate simulation framework. The isoprene production is calculated as a function of electron transport-limited photosynthesis, interce
Popular Abstract in Swedish Höftfraktur är en vanlig skada, som huvudsakligen drabbar äldre kvinnor, och oftast orsakas av ett ringa våld. Det är vanlig orsak till funktionsnedsättning, sjuklighet och dödlighet hos de äldre. Både incidensen (antal nya fall per antal innevånare och år) av höftfrakturer och det totala antalet har ökat de senaste årtiondena. Höftfrakturer medför stora kostnader för sHip fractures are a common cause of morbidity and mortality in elderly patients, with a high risk of functional impairment and institutionalization. The incidence and number of hip fractures have increased during the recent decades and hip fractures consume considerable health-care resources. The incidence of hip fractures in Malmö, Sweden, 1992–95, is described in Paper I. The annual incidence pe
E-business is becoming more and more common today. The predictions of future growth give clear indications that companies will use e-business more and more. However in the growth of e-business it has been identified that there is a common lack of understanding in customer needs and logistics. In order to reduce some of this non-understanding this thesis seeks answers to the following question: - H
Popular Abstract in Swedish Bakgrund: Öroninflammation är vanligt förekommande i barnaåren. De flesta barn har haft minst en episod med akut varig öroninflammation (AOM) och/eller en period med vätska i mellanörat (SOM) före skolstart. De flesta får enstaka episoder, frekvensen av AOM avtar i 2-års åldern och frekvensen av SOM avtar före skolstart. Efter en AOM episod är det vanligt att man under Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. Subjects and methods: Out of a birth cohort followed to the age of 3 years, 12 child
Several commercially available systems for attenuation correction in single photon emission computed tomography (SPECT) based on a transmission scan have been introduced that vary in performance. A test procedure for attenuation correction in SPECT is described and applied to two principally different gamma camera systems (the Siemens Multispect 3 triple-headed system [3HS] and the ADAC Genesys Ve
Spatio-temporal Hawkes processes are a natural way of modelling point process data. They are used in a range of contexts for their ability to separate ”background” arrivals from secondary spread events, yet standard inference algorithms work from a complete event history. Motivated by a study looking at photographic records of an invasive rose-bush population with irregular time intervals between
Parkinson’s disease (PD) is a progressive neurodegenerative disease, characterized by degeneration of dopaminergic neurons, leading to notable difficulties with one’s movement. Among different treatment options, stem cell replacement therapies have been recognized as an option to not only treat disease symptoms but to address its underlying cause- neuronal degeneration. This can be achieved throug
IntroductionWater scarcity is a growing problem, with estimates showing that 40% of the world’s population could face water shortages by 2030. This issue is even worse because only 3% of the Earth’s water is freshwater, while 97% is seawater. Finding better ways to save and use water is critical to solving this problem. At the same time, renewable energy is essential for reducing carbon emissions
