BACKGROUND: Peripheral artery disease is considered to be a manifestation of systemic atherosclerosis with associated adverse cardiovascular and limb events. Data from previous trials have suggested that patients receiving clopidogrel monotherapy had a lower risk of cardiovascular events than those receiving aspirin. We wanted to compare clopidogrel with ticagrelor, a potent antiplatelet agent, in

Despite laws, policies, and political visions to create cities and societies for all, barriers still exclude people from using buildings and public places. The commitments made in global agreements such as the Convention on Rights for Persons with Disabilities (CRPD) and the 2030 Agenda for Sustainable Development require significant changes in urban planning to meet the variety of needs and condi

This study develops a framework for spatiotemporal modeling of dust storm source susceptibility in a critical case study, the Tigris-Euphrates River Basin, as a significant source of dust storms in the Middle East. The study period was divided into four periods, 2000–2004 (hydrological dry year), 2005–2007 (hydrological wet year), 2008–2012 (hydrological dry year), and 2013–2021 (hydrological wet

Attention Restoration Theory point to nature as a particularly good candidate for restoring the ability to focus and inhibit distractions. However, little effort has been directed to elaborating on what makes nature's visual pattern unique for restoration purposes. One suggested explanation is the fractal properties of natural patterns (Hagerhall, 2005). Both perception studies (Hagerhall et al.,

The aim of this study was to achieve realistic levels of two different types of aerosols commonly abundant in indoor environments in an experimental chamber intended for human exposure studies and aerosol characterization. The aerosols chosen were particles from candle lights (in particle number dominated by inorganic water soluble particles) and from ozone-terpene reactions (organic particles). T

Background : In order to increase access to antiretroviral therapy (ART) in HIV-infected children, paediatric HIV care has been introduced in health centres in Ethiopia, where patients are managed by health professionals with limited training. Objective : To compare outcomes of paediatric HIV care in hospital and health centre clinics and to determine risk factors for death and loss to follow-up (

A method of realigning the quadrupole magnets in storage rings to achieve minimum dipole corrector strengths is described. The corrector strengths after realignment are mainly determined by Beam Position Monitor offsets relative to the quadrupole magnets they have been calibrated against and the extent to which magnet dipole errors stay constant during the realignment. The accuracy to which quadru

Objective. The first successful pregnancy after heart transplantation was reported in 1988. Worldwide experience with heart and heart/lung transplanted (H-HLTx) pregnant women is limited. To expand this knowledge the collaborating Nordic thoracic transplant centers wanted to collect information on all such pregnancies from their centers. Design. Information was retrospectively collected on all H-H

Background: Sweden is a high endemic region for multiple sclerosis (MS), a neurologic disorder characterized by repeated inflammatory episodes affecting the CNS. The disease has its peak age of onset at approximately 30 years and affects women twice as often as men. The young age of onset makes MS one of the major causes of reduced capacity to work due to neurologic disease in Western society. Nat

Objectives To describe clinical history and ultrasound findings in patients with tubal carcinoma. Methods Patients with a histological diagnosis of tubal cancer who had undergone preoperative ultrasound examination were identified from the databases of 13 ultrasound centers. The tumors were described by the principal investigator at each contributing center on the basis of ultrasound images, ultra

Objectives - People who suffer a stroke are at risk of developing post-stroke depression (PSD). Not only does this lower their quality of life but it also increases their risk of another stroke or d

Popular Abstract in Swedish Inom forskningsområdet biogeokemi studerar man hur naturens olika grundämnen, såsom kol, kväve, fosfor och kisel ändrar form och transporteras genom landskapet för att via bäckar och vattendrag till slut nå havet. Tillsammans beskriver dessa olika processer, som sker på olika tidsskalor, från sekunder till flera miljoner år, ett grundämnes kretslopp (eller biogeokemiskaSilicon is the next most abundant element in the Earth’s crust and its biogeochemical cycle is linked with that of carbon. Further, silicon is a beneficial nutrient for plants in terrestrial ecosystems and a key nutrient for diatoms in aquatic ecosystems. During the last decade the important role of terrestrial vegetation in controlling Si fluxes downstream aquatic environments, via incorporation

My PhD submission is made up of a constellation of three elements that form a body of textual material / theory and practice event / exhibition. (1) A dimension of critical writing or dissertation that has two parts: (a) Retrospective / Prospective: Activating the Archive, September 1, 2010, and (b) an accretion of further analysis, Archive, Archived, Archiving, September 1, 2011. (2) A testin

Introduction Aniridia (iris more or less missing), is a congenital, dominant, inherited, serious and sight-threatening disease, most often appearing as an isolated eye disorder. It is caused by mutations in the PAX6 gene, the master gene of the development of the eye. Typically, Aniridia causes severe visual impairment. In addition to glare caused by the iris defect, underdevelopment of the macula

The topic of this thesis is estimation of nonlinear dynamical systems, focusing on the use of methods such as particle filtering and smoothing. There are three areas of contributions: software implementation, applications of nonlinear estimation and some theoretical extensions to existing algorithms. The common theme for all the work presented is the pyParticleEst software framework, which has b

This thesis is a pilot study for cross-disciplinary analysis with the aim to compare the prerequisites for sustainable harvesting of forest residues/fuels in southern and northern Sweden from both environmental and societal perspectives. It has three main focus areas: (A) Potential to produce forest fuels; (B) Effects on the nutrient budget; and (C) Practical aspects and attitudes within the fores

Populärvetenskaplig sammanfattning Fenologi innebär studier av naturligt återkommande händelser som till exempel bladsprickning, knoppbristning och vissningen av blad. Det är viktigt att förstå hur klimatförändringen påverkar tidpunkten då dessa händelser sker eftersom det i sin tur påverkar kol-, närings- och den hydrologiska cykeln. Fältobservationer har varit den mest använda metoden för att saPhenology is the study of the timing of natural events such as leaf-out, bud burst and senescence relative to climate change. It is important to understand how the climate change will affect the timing of these events as it in turn affects the carbon-, nutrient- and the hydrological cycles. Field observations is the most common way to gather phenology data but the result is dependent on the skill

Summary: The magnetic field surrounding the Earth has repeatedly been shown to be used by various animals for navigation purposes. There is not yet any published data on the existence of a magnetic sense in a bumblebee. I here present the development of a method suitable for examining the existence of a magnetic sense in the buff-tailed bumblebee (Bombus terrestris) by using a four-armed maze loca

A great number of studies have explored the motivations that drive software developers to devote their time and efforts to contribute to Open Source Software Development (OSSD) projects. Previous studies have stated that both intrinsic and extrinsic motivations are important, however there have been different opinions regarding their relative value. This study further researches OSSD motivations a
