Mobility particle size spectrometers often referred to as DMPS (Differential Mobility Particle Sizers) or SMPS (Scanning Mobility Particle Sizers) have found a wide range of applications in atmospheric aerosol research. However, comparability of measurements conducted world-wide is hampered by lack of generally accepted technical standards and guidelines with respect to the instrumental set-up, me

In healthy subjects, acute inhalation of swine dust causes an influx of inflammatory cells into the airways and increased bronchial responsiveness. The exposure may also cause fever and generalized symptoms. It seems likely that proinflammatory cytokines are involved in the response to inhaled swine dust. Nasal and bronchoalveolar lavage (BAL) were performed before, and 7 and 24 h after the start

Som ett led i de åtaganden som ställs på de länder som har undertecknat Kyotoprotokollet måste landvisa kolbudgetar fastställas. För att fastlägga bra kolbudgetar är det viktigt att kunna göra bra uppskattningar av kolmängden inom olika geografiska områden. Detta dels för att kunna uppskatta befintliga mängder och dels för att kunna påvisa förändringar över tiden. Denna studie hade som huvudmål atAs part of the undertakings of the Kyoto treaty, country-wise carbon balances must be brought forward. To do this, it is important to be able to make good estimations of the amount of carbon in forest areas. The reasons for this are to estimate the existing amounts as well as to prove changes over time. The main goal of this study was to estimate the amount of carbon stored in trees in a hundred-y

This Master’s Thesis, under the Division of Machine Design at Lund Institute of Technology, was conducted at Presona AB located in Tomelilla, Sweden during the first half of 2006. Presona AB is a leading manufacturer of equipment for handling and compression of waste. The object of the thesis is to reduce the manufacturing cost of Presona’s heavy duty stationary compactor. This is acquired by rede

Background: Abdominal obesity is on the increase worldwide and ethnic minority groups are at high risk. However, studies of the underlying causes are scarce. The aims of this study were to investigate the prevalence of abdominal obesity and to identify metabolic, lifestyle and socio-demographic risk factors associated with abdominal obesity in male and female residents of Malmö, a city in southern

Background: Postural Orthostatic Tachycardia Syndrome (POTS) is a cardiovascular dysautonomic condition affecting predominantly young women. POTS is defined as the presence of chronic symptoms of orthostatic intolerance associated with an increased heart rate ≥30 bpm, or heart rate exceeding 120 bpm, within 10 minutes of standing or head-up tilt in the absence of orthostatic hypotension. The etio

Vascular risk factors are believed to be involved in dementia development by increasing risk of the most common dementia types, Alzheimer’s disease (AD) and vascular dementia. The aim of this thesis was to study if risk factors affect key brain pathology directly, by using biomarkers for dementia in preclinical stages, and to assess previous findings in a large population-based setting.Paper I: ar

Popular Abstract in Swedish Sambanden mellan kostens sammansättning och risk för hjärt-kärlsjukdom är i många fall oklara. En kost rik på fleromättade fettsyror har ansetts kunna ge skydd mot hjärt-kärlsjukdom, men resultaten från olika studier är motstridiga. En anledning till detta kan vara för att man inte har tagit hänsyn till de genetiska skillnader som finns mellan individer. Omega-3 och oIn previous studies, a high quality diet has been associated with a reduced risk of cardiovascular disease (CVD) compared to a low diet quality, and specific “healthy” diet components, such as polyunsaturated fatty acids (PUFAs), have been hypothesized to reduce the risk of CVD. However, results from epidemiological studies have been conflicting. This may be due to individuals having varied geneti

The possibility that long-term atmospheric nitrogen pollution and fertilization of forest soil may serve as a basis for adaptation for enhanced transformation rates of NO3- and NH4+ in soil. bacteria was elucidated in a laboratory bioassay. Bacteria extracted from soils that had been fertilized at various rates for the last 30 yr were characterised with respect to their capability to reduce or oxi

Context Inpatients with nonvalvular atrial fibrillation, warfarin prevents ischemic stroke, but dose adjustment, coagulation monitoring, and bleeding limit its use. Objective To compare the efficacy of the oral direct thrombin inhibitor ximelagatran with warfarin for prevention of stroke and systemic embolism. Design, Setting, and Participants Double-blind, randomized, multicenter trial (20002001)

För den spirande miljömedvetenheten på 1960-talet måste det har tett sig uppenbart att den socialistiska rörelsen – på båda sidor om verkliga och ideologiska murar – prioriterade sysselsättning och växande (privat och offentligt) konsumtionsutrymme långt före ekologiska hållbarhetsfrågor, och trots att miljöpolitik nu har lagts till andra politikområden har den prioritetsordningen knappast ändrats

Introduction: Although Alzheimer’s disease (AD) is associated with early death, its life expectancy differs greatly between patients. A better understanding of this heterogeneity may reveal important disease mechanisms underlying the malignancy of AD. The aim of this study was to examine the relation between AD pathologies and early death in AD caused by dementia. Methods: At a memory clinic, 247

Background: The benefits of exercise in mild and moderate knee or hip osteoarthritis (OA) are apparent, but the evidence in severe OA is less clear. We recently reported that neuromuscular training was well tolerated and feasible in patients with severe primary hip or knee OA. The aims of this controlled before-and-after study were to compare baseline status to an age-matched population-based refe

Optical spectroscopy has been used as a supplement to conventional techniques for analyzing and diagnosing cancer in many human organs. Because ocular tumors may be characterized by their different melanin content, we investigated the feasibility of using transscleral visible/near-infrared spectroscopy (Vis/NIRS) to estimate the quantity of melanin in a novel uveal melanoma phantom of ex vivo porc

The understanding of biochemical feedback mechanisms in the climate system is lacking knowledge in relation to bi-directional ammonia (NH3) exchange between natural ecosystems and the atmosphere. We therefore study the atmospheric NH3 fluxes during a 25-day period during autumn 2010 (21 October to 15 November) for the Danish beech forest Lille Bogeskov to address the hypothesis that NH3 emissions

Action plan for the conservation of Psora vallesiaca Psora vallesiaca is red-listed in Sweden and assigned to the category Critically Endangered (CR). In Sweden it is known from one locality on Öland where it grows in a small population of about 30 individuals. In the spring of 2006, four new localities were discovered on Gotland. The main distribution of Psora vallesiaca streches from the Mediter

This is the fifth annual report of the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedish

BACKGROUND: Opioid-related deaths have increased in Western countries over recent decades. Despite numerous studies investigating opioid-related mortality, only a few have focused on the lives of the deceased individuals prior to their deaths, specifically regarding contact with care-providing authorities such as health, social and correctional services. Furthermore, a change has been noted in the

Background: An Okinawa-based Nordic diet with moderately low carbohydrate content and high fat and protein content has been shown to improve anthropometry and metabolism in type 2 diabetes.Objective: The objectives of this study were to measure plasma or serum levels of hormones regulating energy metabolism and metabolic control, that is, cholecystokinin (CCK), Cortisol, C-peptide, ghrelin, glucag
