Stricter building regulations have resulted in the construction of buildings with a low energy use during the operation phase. It has now become increasingly important to also look at the embodied energy, because it might, over the lifespan of the building, equal the energy used for operating the building. One way to decrease the embodied energy is to reuse building materials and components or to
The objective was to investigate if diffusing laser fibres can be modelled as conductive heat sources without miscalculating coagulated volumes, and if finite element analysis, disregarding light transport, may be used for three dimensional (3D) treatment planning in interstitial laser thermotherapy (ILT). Temperature distributions and coagulated volumes with a diffusing laser fibre, as compared t
Microbial decomposers process a great majority of net primary production in the biosphere and regulate carbon (C) and nutrient cycling. Microbial communities are extremely diverse and often disregarded from global C-cycling models, but one strategy to overcome this challenge is to focus on the major decomposer groups: fungi and bacteria. These groups have distinct life strategies and are different
To utilize sugars as a feedstock for renewable industries, the feedstock often needs to be very pure. This is due to ionic species contaminating the sugar feedstock being potent catalyst poisons in many cases. To remove ionic species from the sugar feedstock, it is dissolved and purified using packed ion-exchange columns. In this report, a lab-scale setup of a large scale ion-exchange setup was co
Previous research shows that gambling addiction receives less attention in Social services compared with substance abuse. The aim of the study was to compare the child-welfare officer’s view on problem for the child and also on support and assistance for children who grow up in families where parents are compulsive gamblers than in families where parents have a substance abuse (in this paper it wi
Uppsatsens syfte är att undersöka vilka motiv för börsintroduktion som angavs av de svenska bolag som noterades på Stockholmsbörsen 1997 och att undersöka huruvida bolagens ledning anser att målen med de angivna motiven har motsvarat förväntningarna, samt att undersöka vilka andra eventuella effekter börsintroduktionen har medfört. Vi har som helhet genomfört en kvalitativ studie. Vår undersökning
On- and off-line heterogeneous non-competitive flow immunoassays for the determination of Interleukin-10 are described. The sample containing IL-10 is mixed, either on-line in a reaction coil or off-line in a test tube, with fluorescent labelled anti-IL-10 antibodies to form an antibody-antigen complex. The labelled unbound antibodies are trapped on an immobilized IL-10 column whereas the IL-10-an
We prospectively investigated anti-Müllerian hormone (AMH) as a measure of ovarian insult in young females during and after treatment for Wilms tumor (WT), osteosarcoma (OS), and Ewing sarcoma (ES). Twenty-one female childhood cancer patients, with a mean age of 7.9 years (range 0.6-17), entered the study. Levels of AMH, follicle-stimulating hormone (FSH), and luteinizing hormone were monitored at
We address the problem of optimizing resource allocation for Perceptually based Unequal Packet Protection (PUPP) in a packet based voice carrying network. For that purpose, we design a novel real-time working Perceptually Based Classifier (PBC) optimizing the assignment of voice packets to either a Premium (Pch) or an Ordinary (Och) transmission Channel with regard to packet perceptual importance.
Objectives. To assess waiting times for three groups of orthopaedic patients in Sweden and to identify factors explaining variations in waiting time. Also examined were factors associated with patients' perceptions that waiting times were too long. Design. Retrospective study. Setting and study participants. Patients from orthopaedic units at 10 Swedish hospitals participated in the study. A quest
Redan romarna anlade fältsjukhus i natursköna områden för att rehabiliteringen skulle fungera bra. Även i modern tid har man uppfört sjukhus i parkmiljöer i syfte att förbättra hälsan hos patienterna. Sjukhusen har gärna utformats så att det är lätt att ta sig ut till de omgivande markerna, fönstren vetter utåt och trädgårdar planeras för att ge patienterna kontakt med naturmiljön. I slutet av 180
An increasing incidence of testicular cancer has been reported from several western countries during the last decades. According to current hypothesis testicular cancer is initiated during the foetal period and exposure to endocrine disruptors such as some persistent organic pollutants has been of concern. We have previously reported the results for concentrations of polychlorinated biphenyls (PCB
The purpose of this study was to examine the relation between poor sleep and nonsuicidal self-injury (NSSI), and to test the hypothesis that poor sleep is a risk factor for the development of NSSI in young adolescents. Questionnaire data were used from a 2-wave longitudinal study of a community sample of 881 young Swedish adolescents. The results showed that 7 % of the girls reported poor sleep (n
OBJECTIVE: To determine which factors increase the risk of large caesarean scar defects as assessed by transvaginal ultrasound. DESIGN: Observational cross-sectional study. SETTING: University Hospital. POPULATION: One hundred and eight women who had undergone one caesarean section. METHODS: Transvaginal ultrasound examination of the scar in the uterus 6-9 months after the caesarean. Published ult
BACKGROUND: Infections caused by Chlamydia pneumoniae are considered to participate in inflammatory processes leading to coronary artery disease. After a primary infection, the bacteria remain dormant intracellularly causing a chronic inflammatory stimulus. MATERIALS AND METHODS: Blood samples were obtained from 235 patients with acute myocardial infarction (AMI) and 108 patients with unstable ang
We report a population based case-control study of exposure to pesticides as risk factor for non-Hodgkin lymphoma (NHL). Male and female subjects aged 18-74 years living in Sweden were included during December 1, 1999, to April 30, 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnaire. In total 910 (91 %) cases and 1016 (92%)
