Populärvetenskaplig sammanfattning: Kolcykeln är enkelt uttryckt den globala balansräkningen av kolets (C) förflyttning genom olika sfärer såsom mellan atmosfären och biosfären, således är kolcykeln av stor betydelse för mänsklighetens existens. Exempelvis har atmosfäriska koncentrationer av koldioxid (CO2) och metan (CH4) ökat de senaste 200 hundra åren på grund av mänskliga aktiviteter (till stoCarbon is central to our existence. It plays a fundamental role in the carbon cycle. Atmospheric concentrations of carbon dioxide (CO2) and methane (CH4) have been increasing for about two centuries as a result of human activities. The need to understand how carbon cycles through the Earth-system is important for a variety of reasons, but mainly in order to assess the effects of these rising green

A risk evaluation with regards to fire safety has been performed at Torpa Stenhus. The focus of the evaluation was the safety of the people inside the building in case of a fire. As part of the education for future fire protection engineers at LTH a risk evaluation report is performed in the course Brandteknisk riskvärdering (VBR054). Torpa Stenhus was built during the 15th century and is located

ABSTRACT The purpose of this study is to examine how young adults with non-European background and with an upbringing in a city associate to nature and what may have influenced these associations. Given that a majority of people live in cities, there is a risk that many young people do not spend time in natural environments, which may affect their associations to nature and also their environment

This study aims to investigate whether the Internet can be a useful tool in organisations in developing countries that are working for empowerment, democratisation and an increased global justice. I have elucidated the opportunities involved and the prerequisites for it to happen. The ability for groups to interact at great distances and at a rapid speed raises interesting questions about collecti

Objective: Objective measures of function are important in rheumatoid arthritis (RA). The objective of this study was to investigate grip strength in patients with early RA. Methods: An inception cohort of 225 patients with early RA was followed in accordance with a structured protocol. Average and peak grip force values of the dominant hand (measured using a Grippit device [AB Detektor]) were eva

Due to increased awareness of climate change and higher energy costs, well‐insulated buildings have become more common. Furthermore, the interests of using wood in building to produce more carbon dioxide‐efficient houses have increased. However, thicker thermal insulation in walls increases the risk of high relative humidity levels and the risk of mould‐related damage in Wood frame houses. In orde

Models of moisture flow processes in wood are normally based on a Fickian approach. In many instances, there are considerable discrepancies between modelling and experimental results. It is shown in this thesis that a major cause for these discrepancies is a so-called retarded sorption which is not accounted for in conventional theories. This retarded sorption occurs in the wood cell wall. A spec

BACKGROUND: In select patients with heart failure, cardiac resynchronization therapy (CRT) is the most common complementary treatment besides medical treatment. We aimed to assess the association between post CRT-implant changes in cardiovascular medication and cardiovascular mortality and heart failure hospitalization.METHODS: 211 patients on optimal medical therapy eligible for CRT were retrospe

This is the first study which quantifies aggrecan fragments, stromelysin-1 and tissue inhibitor of metalloproteinases-1 (TIMP-1) in SF samples prospectively obtained from the same patient at different time intervals after a cruciate ligament injury of the knee. Aggrecan fragment concentrations were determined by dye precipitation with Alcian Blue. Stromelysin-1 and TIMP-1 were analysed by immunoas

Through new tracking techniques, data on timing and routes of migration in long-distance migrant birds are accumulating. However, studies of the consistency of migration of the same individuals between years are still rare in small-sized passerine birds. This type of information is important to understand decisions and migration abilities at the individual level, but also for life history theory,

AIM: To investigate whether overweight/obesity at diagnosis affects the chances of decrease in disease activity and pain in early rheumatoid arthritis (RA).METHOD: We investigated incident RA cases from the population-based Epidemiological Investigation of risk factors for Rheumatoid Arthritis (EIRA) study (2006-2009, N=495) with clinical follow-up in the Swedish Rheumatology Quality Register. At

Background: Few studies have analysed the long-term effects of biological treatment in psoriasis. PsoReg, the Swedish national register for systemic psoriasis treatment, started in 2006 and now includes 10 years of real-world data on the effectiveness of biological treatment. Objectives: To analyse the long-term real-world outcome data of patients who are biologically naïve with moderate-to-severe

Objectives: To test the utility of the World Health Organization (WHO) and International Society of Nephrology/Renal Pathology Society (ISN/RPS) criteria for lupus nephritis (LN) in systemic lupus erythematosus (SLE) and the American College of Rheumatology renal response criteria (ACR-RRC) for renal follow-up in an observational cohort. Method: All 52 biopsy-verified cases of LN during 19 years w

Popular Abstract in Swedish Äta och ätas Om hur kannibaler och tjuvar kan påverka en sjö Gäddor är kannibaler och stjäl ofta byten från varandra. Risken för överfall ökar med storleken på det byte gäddan äter. För att undvika att bli utsatta för dessa påhopp, väljer gäddor i första hand små och lågryggade byten, eftersom dessa är lättare att svälja och därigenom minskar risken. Därigenom låter gOptimal foraging and prey preference in top predators may affect population and community dynamics and structure. Also, optimal foraging and prey preference may shift with prevailing conditions, and therefore create changes in the effect of predation. In this thesis, I examine the effects of intraspecific interactions among northern pike on pike predatory behaviour, prey preference, and subsequent

Significant efforts were invested in halting the recent Ebola virus disease outbreak in West Africa. Now, studies are emerging on the magnitude of the indirect health effects of the outbreak in the affected countries, and the aim of this study is to systematically assess the results of these publications. The methodology for this review adhered to the Prisma guidelines for systematic reviews. A to

CONTEXT: The natural course of HIV disease progression among resource-poor patient populations has not been clearly defined.OBJECTIVE: To describe predictors of HIV disease progression as seen at an outpatient clinic in a resource-limited setting in rural Ethiopia.DESIGN: This prospective cohort study included all adult HIV patients who visited an outpatient clinic at Arba Minch hospital in South

The aim is to test the reliability of two alcohol screening instruments: (1) The Parent Alcohol Screening Questionnaire (PASQ5), and (2) the Social Support for an Alcohol-free Pregnancy (SSAFP) questionnaire. This is a cohort study from the south of Sweden using repeated surveys during pregnancy. To examine if responses differed according to different data collection methods, two cohorts consistin

The importance of wild bees for crop pollination is well established, but less is known about which species contribute to service delivery to inform agricultural management, monitoring and conservation. Using sites in Great Britain as a case study, we use a novel qualitative approach combining ecological information and field survey data to establish a national list of crop pollinating bees for fo

Objective: To estimate direct and indirect costs associated with neuropsychiatric (NP) events in the Systemic Lupus International Collaborating Clinics inception cohort. Methods: NP events were documented annually using American College of Rheumatology definitions for NP events and attributed to systemic lupus erythematosus (SLE) or non-SLE causes. Patients were stratified into 1 of 3 NP states (n

Aim: Macroecological analyses provide valuable insights into factors that influence how parasites are distributed across space and among hosts. Amid large uncertainties that arise when generalizing from local and regional findings, hierarchical approaches applied to global datasets are required to determine whether drivers of parasite infection patterns vary across scales. We assessed global patte
