The mitral annulus (MA) has a complex shape and motion, and its excursion has been correlated to left ventricular (LV) function. During the cardiac cycle the annulus' excursion encompasses a volume that is part of the total LV volume change during both filling and emptying. Our objective was to evaluate the contribution of MA excursion and shape variation to total LV volume change. Nine healthy su
By exposing photosystem II (PSII) samples to an incrementing number of excitation flashes at room temperature, followed by freezing, we could compare the Mn-derived multiline EPR signal from the S-2 oxidation state as prepared by 1, 5, 10, and 25 flashes of light. While the S-2 multiline signals exhibited by these samples differed very little in spectral shape, a significant increase of the relaxa
The assessment of effects of anthropogenic disturbance on biodiversity (BD) and ecosystem services (ES) and their relationships are key priorities of the Intergovernmental Panel for Biodiversity and Ecosystem Services. Agricultural landscapes and their associated BD provide multiple ES and it is crucial to understand how relationships between ES and BD components change along gradients of landscap
Background: Cardiac rehabilitation improves prognosis after an acute myocardial infarction (AMI), however, the optimal method of implementation is unknown. The aim of the study was to evaluate the effect of individually-tailored, nurse-led cardiac rehabilitation on patient outcomes. Method: This single-centre retrospective observational study included 217 patients (62±9years, 73% men). All patient
Feedbacks between the intertwined water and carbon cycles in semi-arid mountain ecosystems can introduce large uncertainties into projections of carbon storage. In this study, we sought to understand the influence of key mechanisms on carbon balances, focusing on an ecosystem whose complex terrain and large interannual variability in precipitation adds to its vulnerability to warming. We applied a
Background: Adolescent major depressive disorder (MDD) is highly prevalent and associated with lifelong adversity. Evidence-based treatments exist, but accessible treatment alternatives are needed. We aimed to compare internet-based psychodynamic therapy (IPDT) with an established evidence-based treatment (internet-based cognitive behavioural therapy [ICBT]) for the treatment of adolescents with d
This longitudinal study used a multi-disciplinary approach and examined the relationship between psychosocial and health characteristics and the pattern of informal and formal support for non-institutionalized very old people. The data were derived from a single cohort of 80-year-old people living in Lund, Sweden who were followed over a 3-year period. In order to account for potential sample bias
Many flying animals, like birds feeding their young, make commuting flights between a central place and foraging areas in the surroundings. Such central place foraging (CPF) represents a special case of foraging theory. We use simple geometry and trigonometry to analyse CPF flight performance (a round-trip cycle of outward flight from the central place and inward flight back along the reverse trac
Atmospheric deposition is a source of inorganic nutrients and organic matter to the ocean, and can favor the growth of some planktonic species over others according to their nutrient requirements. Atmospheric inputs from natural and anthropogenic sources are nowadays increasing due to desertification and industrialization, respectively. While the impact of mineral dust (mainly from the Saharan des
The thesis deals with consumers behaviour in the use of online services and the cultures effect on it. It is a study of Swedes and Danes use of online job data bases. The thesis is based on a quantitative study. A questionnaire were used sent out to 80 Swedes and 80 Danes. The theory concerns areas of online consumer behaviour, decision making and services theory as well as theories within culture
Införandet av en så kallad samtyckeslag har varit kraftigt omdebatterat i över två decenniers tid. Den 1 juli 2018 infördes en våldtäktsbestämmelse som baseras på frivillighet. I och med detta utvidgades våldtäktsbestämmelsen på så sätt att det inte längre fordras tvång eller utnyttjande av en särskilt utsatt situation för att straffansvar ska aktualiseras. Syftet med den nya våldtäktsbe-stämmelseThe adoption of a so-called consent-based rape law has been heavily debated for over two decades. On July 1st, 2018 a rape clause based on voluntarism was introduced. As a result, the rape regulation was extended in such a way that it no longer requires force, or exploitation of a particular vulnerable situa-tion, for criminal liability to occur. The purpose of the new rape regulation is to protec
Malaria is a global health issue affecting hundreds of millions of people worldwide and accounts for as much as 405 000 deaths annually. Preventative actions are taken but are seemingly not enough to eradicate the spread. Targeting underlying molecular mechanisms behind the host-seeking behavior of the principal malaria vector Anopheles gambiae, would offer a new approach in the development of an
The incidence of the most common fracture types in Iceland is reported based on individual data from the Reykjavik Study 1967-2008. Time trend is reported for the major osteoporotic fractures (MOS) 1989-2008. This study aims to assess the incidence of all fractures in Iceland, with emphasis on the rate of hip fractures, and compare the incidence with other populations as well as examine the secula
Field observations and experimental data of effects of nitrogen (N) deposition oil plant species diversity have been Used to derive empirical critical N loads for various ecosystems. The great advantage of such an approach is the inclusion of field evidence, but there are also restrictions, such as the absence of explicit criteria regarding significant effects on the vegetation, and the impossibil
The land use, land-use change, and forestry sector (LULUCF) has historically been rather unregulated. Recent political developments have put pressure on countries to implement practices that increase net greenhouse gas (GHG) removals and improve the state of carbon sinks. One of these political developments is the European Union’s (EU) LULUCF Regulation, which as of now obligates Member States (MS
The planetary boundaries (PBs) framework defines a "safe operating space" based on nine key Earth system processes. Out of these, four are terrestrial, and their primary driver of transgression is agriculture. To better understand how agricultural activities might further influence the terrestrial PBs, it is essential to model their drivers and interactions over time. A helpful tool for
Albania is a country situated in the western Balkan peninsula, it is a parliamentary democracy and a transitional economy. Its population is approximately 3.5 million with 870.00 populating its capital Tirana.1 The Mediterranean country underwent its most difficult times during the communist regime, where the dictator Enver Hoxha ruled the country with an iron fist for 40 years. His policies exerc
Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. This makes them highly eligible in spectroscopic applications used in many re
Den tekniska utvecklingen och förändrade arbetsformer gör att det i dag är enklare än någonsin för arbetsgivare att kontrollera och övervaka arbetstagare. Under senare år har det blivit allt vanligare att arbetsgivare övervakar arbetstagares elektroniska kommunikation. Med elektronisk kommunikation avses arbetstagares kommunikation via användningen av arbetsgivares IT-utrustning och internetanslutDue to technical developments and changed forms of working, it is now easier than ever for employers to control and monitor employees. In recent years, it has become increasingly common for employers to monitor employees’ electronic communications. Electronic communication refers to employee communication via the use of the employer’s IT equipment and internet connection. The most prevalent form o
Incorporating a multi-year grass ley into an arable crop rotation can increase soil organic carbon stocks, reduce carbon emissions and provide feedstock for biogas. This thesis set out to study how a policy promoting agricultural biomass for biogas impacts GHG emissions and carbon sequestration on a regional level over a temporal scale of 20 years. This was done in the specific case of policy prom
