The purpose of this thesis project was to analyse and evaluate different systems for installation of piperun in ceilings. Main focus lay on how the systems influence the installer from an ergonomic point of view as well as productivity in terms of installation time. Several studies have been performed during this project using a variety of methods such as observations, interviews, questionnaires a
Abstract The blue gum psyllid, Ctenarytaina eucalypti (Homoptera: Psylloidea), is an economic threat to Eucalyptus plantations worldwide. To date, no efficient control method is available for this pest and the potential for semiochemical-based monitoring or control methods have not yet been investigated. Hence, I conducted the first study on the olfactory sense of C. eucalypti, investigating the
Background & Problem: In previous years, there has been low focus on inventory control. Due to high margins on the products, a high inventory level has been kept to reduce the risk for lost sales. Today, the company is expanding, and therefore need to improve the inventory control to reduce tied-up capital. Purpose: The main purpose of this thesis is to reduce capital tied-up in inventories. B
Muntlig bevisning har länge medfört problem i den svenska hovrätten. När ett mål når den andra instansen har kvaliteten på muntlig bevisning blivit sämre, inte minst på grund av att minnesbilder hos förhörspersoner försvagas med tiden. Trots det har utgångspunkten, allt sedan det muntliga och omedelbara förfarandet introducerades genom 1948 års rättegångsbalk (RB), varit att principen om det bästaOral evidence has caused problems in the Swedish courts of appeals for a long time. When a case reaches the higher court, the quality of oral evidence has deteriorated, primarily because the recollections of witnesses and parties have weakened over time. The starting point has, nevertheless, been that the principle of the best evidence requires renewed questioning of witnesses and parties in the c
Data from measurements on the body burden Of (CS)-C-134, Cs-137 and K-40 in various Swedish populations between 1959 and 2001 has been compiled into a national database. The compilation is a co-operation between the Departments of Radiation Physics in Malmo and Goteborg, the National Radiation Protection Authority (SSI) and the Swedish Defense Research Agency (FOI). In a previous study the effecti
Background: Computed tomography (CT) lung densitometry has been demonstrated to be the most sensitive and specific outcome measure for the assessment of emphysema-modifying therapy, but the optimum densitometric index has yet to be determined and targeted sampling may be more sensitive than whole lung assessment. The EXAcerbations and CT scan as Lung Endpoints (EXACTLE) trial aimed to clarify the
Popular science summary Spatial Memory Accuracy in Marsh tits (Poecile palustris) - an experimental study Food hoarding is a prevalent food protection behaviour in nature and it is performed by variety of animals including some mammals and birds. Two main food hoarding strategies have been observed among animals; larder hoarding and scatter hoarding. Larder hoarders aggregate all their food in
Objective: Previously proposed “synchronous EEG patterns” predict poor outcome within 24 h after cardiac arrest (CA). We investigate the prognostic performance of these early EEG predictors in addition to the late EEG predictors (>24 h) recommended in the European post-resuscitation guidelines. Methods: Observational substudy of the TTM2-trial including consecutive comatose resuscitated patients.
Background: Induced hypothermia after cardiac arrest is neuroprotective in several animal models of cardiac arrest, but few high-quality studies have been conducted in larger animals. Recent clinical trials have questioned the beneficial effects of post-ischemic hypothermia. This study investigated whether immediate cooling or a 2-h delay in cooling to 33 °C after cardiac arrest was neuroprotectiv
The parents’ attitude toward vaccinating children and adolescents against coronavirus disease 2019 (COVID-19) remains inconsistent and needs further elucidation. The high rates of COVID-19 vaccine hesitancy in the Middle East and North Africa (MENA) region require intensive research to understand the determinants of this phenomenon. This study aimed to validate a version of the Parent Attitudes ab
Context. OH/IR stars are examples of late stellar evolution on the asymptotic giant branch (AGB), and they are, as such, important objects to study. They are also excellent probes of stellar populations, in particular in regions of high interstellar extinction such as the central regions of our Galaxy. Aims. Our goal is to characterise the stellar and circumstellar properties of high-mass-loss-rat
Purpose: Acute trauma-related rotator cuff tears are believed to have better healing potential than chronic tears due to less degenerative changes of the tendons. However, the histopathological condition of tendons from trauma-related tears is not well investigated. The purpose of this study was to explore specific histopathological features in tendons from acute trauma-related full-thickness rota
ObjectiveMepolizumab proved to be an efficacious treatment for eosinophilic granulomatosis with polyangiitis (EGPA) at a dose of 300 mg every 4 weeks in the randomized, controlled MIRRA trial. In a few recently reported studies, successful real-life experiences with the approved dose for treating severe eosinophilic asthma (100 mg every 4 weeks) were observed. We undertook this study to assess the
Objectives:This thesis aims to provide an overview of the epidemiology of AAV in southern Sweden, to evaluate different classification criteria in AAV. In addition we study if infection is a risk factor for later development of AAV comparing patients with AAV with a matched population cohort and to examine the occurrence of severe infections as an outcome in AAV. Methods:All adult patients diagnos
Background Genome-wide association studies have so far identified 56 loci associated with risk of coronary artery disease (CAD). Many CAD loci show pleiotropy; that is, they are also associated with other diseases or traits. Objectives This study sought to systematically test if genetic variants identified for non-CAD diseases/traits also associate with CAD and to undertake a comprehensive analysi
Background: Diffusion-weighted imaging plays a key role in magnetic resonance imaging (MRI) of breast tumors. However, it remains unclear how to interpret single diffusion encoding with respect to its link with tissue microstructure. The purpose of this retrospective cross-sectional study was to use tensor-valued diffusion encoding to investigate the underlying microstructure of invasive ductal ca
Objective: To evaluate whether the duration of the active phase of labor is associated with maternal body mass index (BMI), in nulliparous women with spontaneous onset of labor. Study design: Historical prospective cohort study including 63,829 nulliparous women with a singleton pregnancy and a spontaneous onset of labor, who delivered between January 1, 1995 and December 31, 2009. Data were colle
Areal bone mineral density (aBMD), as measured by dual-energy X-ray absorptiometry (DXA), predicts hip fracture risk only moderately. Simulation of bone mechanics based on DXA imaging of the proximal femur, may help to improve the prediction accuracy. Therefore, we collected three (1-3) image sets, including CT images and DXA images of 34 proximal cadaver femurs (set1, including 30 males, 4 female
The N-terminal RNA binding domain of U1A has been shown to fold in a two-state process without accumulating any intermediates. U1A has a symmetrically curved chevron plot which seems to result mainly from changes of the transition state. At low concentrations of denaturant the transition state occurs early in the folding reaction, whereas at high denaturant concentration it moves close to the nati
Background: An accurate medication list at hospital admission is essential for the evaluation and further treatment of patients. The objective of this study was to describe the frequency, type and predictors of errors in medication history, and to evaluate the extent to which standard care corrects these errors.Methods: A descriptive study was carried out in two medical wards in a Swedish hospital
