Undersökning av hur penetrationstalet i bitumen påverkar styvheten av cementstabiliserad asfalt i laboratoriepackade prover

A semi-flexible pavement is a composite material consisting of an open-graded asphalt skeleton with an air void content between 25 - 35% that is filled with a cement sludge. Limited research has been done regarding factors which can affect the mechanical properties of this material. Therefore, this study explores the affect the penetration value of a bitumen has on the stiffness of a semi-flexible

(Un)universal health care for all: A qualitative study exploring the access to health care for Venezuelan migrants in Medellín, Colombia

The aim of this thesis is to understand how migrants perceive their opportunities to access health care, and how underlying factors result in barriers impacting their access to health care and ability to safeguard their health. It does so by answering the research question: How do Venezuelan migrants in Medellín perceive their access to health care? To fulfil the aim and answer the research questi

Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive

Popular Abstract in Swedish The phenol oxidase “laccase” was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. However, its use in one of the oldest biotechnologies, i.e. the making of lacquerware in East-Asia, dates back to 5000-6000 BC. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes one elecLaccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product. Based on these highly desired mild oxidising conditio

Measurement of MR signal and T2* in lung to characterize a tight skin mouse model of emphysema using single-point imaging

PURPOSE: To evaluate whether MRI signal and T2* measurements of lung tissue acquired at ultrashort detection times (tds) can detect emphysematous changes in lungs.MATERIALS AND METHODS: MR signal intensity of in vivo mouse lungs was measured at 4.7 T at tds of 0.2 and 0.4 msec using single-point imaging (SPI). T2* was calculated from the measurements obtained at the two tds. Two groups of 8- and 3

New results for Compton scattering on deuterium : A better determination of the neutron electromagnetic polarizabilities

The electric and magnetic polarizabilities of the proton are now well known, owing to Compton scattering measurements on hydrogen targets; however, the neutron polarizabilities are still relatively uncertain, compared to the proton values. To address this problem, a multiinstitutional collaboration has conducted a program of elastic Compton scattering experiments on deuterium at the MAX IV Laborat

Full Scale Firefighting Tests in the Tistbrottet Mine

The paper describes full-scale fire-fighting tests performed in an underground mine. A total of six different methods to fight a full scale fire in a mine tunnel were tested. The methods involved different fire-fighting equipment but were comparable regarding fundamental conditions such as length of response-route, fire-fighting set-up, and smoke and fire size. The aim was to compare different equ

Body mass index and suicide methods

Overweight and obesity is associated with lower rates of suicide. However, little is known about the association with different suicide methods. We studied the association between groups of body mass index and suicide methods. We identified all medicolegal autopsy cases with a cause of death due to external causes in Sweden during 1999-2013 (N = 39,368) and included 11,715 suicides and 13,316 acci

Seasonal variation in biogenic volatile organic compound (BVOC) emissions from Norway spruce in a Swedish boreal forest

Terpene emissions from the top-canopy layer (at 20 m) of one 118-year-old Norway spruce tree were measured between June and September 2013 using a branch chamber. Total terpene emissions varied from 0.05 to 332.5 μg gdw -1 h-1 with a peak in August. Monoterpenes dominated throughout the summer and on average accounted for 65% of the total terpene mass, followed by sesquiterpenes (29%) and isoprene

Achilles tendon compositional and structural properties are altered after unloading by botox

Tendon function and homeostasis rely on external loading. This study investigates the biological mechanisms behind tendon biomechanical function and how the mechanical performance is affected by reduced daily loading. The Achilles tendons of 16 weeks old female Sprague Dawley rats (n = 40) were unloaded for 5 weeks by inducing muscle paralysis with botulinum toxin injections in the right gastrocne

Molecular Characterization of Bladder Cancer Subtypes

Bladder cancer is one of the most common malignancies world-wide, and in Sweden approximately 3000 cases are diagnosed annually. Even though bladder cancer is so common there is low public awareness of the disease, and it has historically been less studied compared to other common types of cancer. This is reflected in the fact that both the treatment methods and outcome for patients have remained

Paquinimod prevents development of diabetes in the non-obese diabetic (NOD) mouse

Quinoline-3-carboxamides (Q compounds) are immunomodulatory compounds that have shown efficacy both in autoimmune disease and cancer. We have in here investigated the impact of one such compound, paquinimod, on the development of diabetes in the NOD mouse model for type I diabetes (T1D). In cohorts of NOD mice treated with paquinimod between weeks 10 to 20 of age and followed up until 40 weeks of

Retrospective incremental cost analysis of a hospital-based COPD Disease Management Programme in Sweden

This paper reports on a retrospective analysis of hospital-based healthcare costs associated with the management of chronic obstructive pulmonary disease (COPD). During the second half of 2001, Simrishamn Hospital, Sweden, implemented a structured Disease Management Programme (DMP) for COPD and a total of 784 patients with COPD, enrolled in the DMP, were included in the analysis. The goal was to r

Insights from past trends in exergy efficiency and carbon intensity of electricity : Portugal, 1900–2014

We use the societal exergy analysis to identify periods and factors controlling efficiency dilution and carbon deepening of electricity in Portugal from 1900 to 2014. Besides estimating the carbon intensity of electricity production, we propose a new indicator, the carbon intensity of electricity use, which quantifies CO 2 /kWh of electricity derived useful exergy. Results show final to useful e

Socioeconomic and occupational groups and risk of asthma in Sweden

AIM: To investigate possible associations between hospitalization for asthma and socioeconomic status and occupation.METHODS: A nationwide database was constructed by linking Swedish Census data to the Hospital Discharge Register (1987-2004). The hospital diagnoses of asthma were based on the International Classification of Diseases. Standardized incidence ratios were calculated for different soci

Amperometric detection of lactose using -galactosidase immobilized in layer-by-layer films

A direct, low-cost method to determine the concentration of lactose is an important goal with possible impact in various types of industry. In this study, a biosensor is reported that exploits the specific interaction between lactose and the enzyme β-galactosidase (β-Gal) normally employed to process lactose into glucose and galactose for lactose-intolerant people. The biosensor was made with β-Ga

Root system estimation based on satellite remote sensing : An applied study in Eastern Uganda

The density of roots is an important factor influencing the rate and magnitude of landslides. Due to the increased variability in climate, mainly rainfall, Eastern Uganda is severely struck by an increasing number of these mass movements, often with human casualties as one of the negative impacts. The aim of this study is to explore the possibility to estimate the depth and density of the root sys
