Philosophers of science have often favoured reductive approaches to how-possibly explanation. This article identifies three varieties of how-possibly explanation and, in so doing, helps to show that this form of explanation is a rich and interesting phenomenon in its own right. The first variety approaches “How is it possible that X?” by showing that, despite appearances, X is not ruled out by wha
Background People who inject drugs (PWID) are at particular risk of hepatitis B virus (HBV) acquisition, but often have poor access or adherence to HBV vaccination. Vaccination against HBV has been offered at a major Swedish needle exchange program (NEP) since 1994. The aim of this study was to evaluate vaccine completion and response rates, and the effect of sequential booster doses to non-respon
English oak (Quercus robur) and European beech (Fagus sylvatica) are amongst the most common tree species growing in Europe, influencing the annual biogenic volatile organic compound (BVOC) budget in this region. Studies have shown great variability in the emissions from these tree species, originating from both genetic variability and differences in climatic conditions between study sites. In thi
Terrestrial ecosystems have absorbed roughly 30 % of anthropogenic CO2 emissions over the past decades, but it is unclear whether this carbon (C) sink will endure into the future. Despite extensive modeling and experimental and observational studies, what fundamentally determines transient dynamics of terrestrial C storage under global change is still not very clear. Here we develop a new framewor
Befolkningen växer och andelen som vill bo i städer ökar stadigt vilket skaparbehov av ny mark att bygga bostäder på. Tidigare har de flesta städer och orterutvecklats genom att växa utåt, vilket har lett till förlust av naturområden ochjordbruksmark och ökat beroendet av bilar. Att bygga staden inåt istället, så kallad förtätning, är numera en populär strategi för att minska bostadsbristen. I denThe proportion of people living in densely built up areas is gradually increasing,forcing cities to generate new land to build homes upon. In this process there is a risk for an inexplicit decrease of green space. The green features ofneighbourhoods help to create a supportive environment for health and physicalactivity, thus a reduction of greenness may reduce the general well-being in thepopulat
BACKGROUND: Societal interest in enabling older workers to prolong their working life has increased in recent years due to demographic change. Managers have a key role in extending working life among employees, because they control the organisation, work environment and potential measures enabling older workers to extend their working life. OBJECTIVE: To examine managers' attitudes to their older
With the theme of the research conference of the NNHSH network we want researchers, both at doctoral and post-doctoral level, to reflect on how health practices and health policies in the Nordic Welfare States are being transformed and have been transformed in the past. The Nordic countries are all, more or less, in the midst of a transformation from a social democratic health care system, based o
Popular Abstract in Swedish Det övergripande syftet med denna avhandling var att studera sambandet mellan skelettmuskulaturens struktur och funktion för att på sikt få ökade kunskaper om de bakomliggande mekanismerna vid muskulär svaghet och uttröttbarhet hos personer med olika skador eller sjukdomar. Mätningarna valdes att göras på musklerna på underbenets framsida, ankelns dorsalflexorer, dels sThe overall aim of this thesis was to increase our knowledge of the relationship between structure and function of human skeletal muscle, and about factors affecting strength. The ankle dorsiflexor muscles (DF) were chosen as a representative model of human skeletal muscle, and because these muscles have important roles in gait and maintenance of balance. Specific aims in this thesis were: i) to d
Agricultural landscapes are characterised by dynamic crop mosaics changing in composition and configuration over space and time. Although semi-natural habitat has been often shown to contribute to pest biological control, the effects of increasing landscape heterogeneity with cropland have been disregarded. Here, we examine how cereal aphids, their enemies and biological control are affected by th
Bacteria and fungi, representing two major soil microorganism groups, play an important role in global nutrient biogeochemistry. Biogeographic patterns of bacterial and fungal biomass are of fundamental importance for mechanistically understanding nutrient cycling. We synthesized 1323 data points of phospholipid fatty acid-derived fungal biomass C (FBC), bacterial biomass C (BBC), and fungi:bacter
Electrical machines, chokes and induction heaters are found in most homes,offices and factories all over the world. They are used to create movement, filtrate the power or to generate heat. A typical unit consist of a coil and a flux conductor material. Some of the materials have been established for over 100 years, while others are only a couple of decades old.A new flux conductor material has be
We present an evaluation of a nested high-resolution Goddard Earth Observing System (GEOS)-Chem chemistry transport model simulation of tropospheric chemistry over tropical South America. The model has been constrained with two isoprene emission inventories: (1) the canopy-scale Model of Emissions of Gases and Aerosols from Nature (MEGAN) and (2) a leaf-scale algorithm coupled to the Lund-Potsdam-
In this study, we first determined the low molecular weight dissolved organic carbon (LMW DOC) concentration-dependent kinetics of soil respiration in a temperate grassland soil sampled on successive occasions. We then used the established relationship to estimate in situ LMW DOC concentrations from basal respiration measurements. C-14-labelled glucose was used as a model substrate and was added t
One of Tetra Pak’s product segments is food filled packages distributed outside the refrigeration chain. These packages are required to keep the content fresh for a long time, up to a year. To achieve this, the inside of the package must stay aseptic until the consumer opens it. In the distribution chain packages will be exposed to different mechanical loads, such as vibrations, shear forces and v
Background: Around 95% of all websites selling medicines globally are illegal and contribute to the spread of substandard and falsified medicines. Hence, it is important to identify legal pharmacies when accessing medicines online. During 2022-2024, 250 million prescriptions were legally dispensed in Sweden, and 69% were prescribed in primary care. Pharmacists and general practitioners are key hea
Water scarcity is a growing global challenge, with projections indicating that 40% of the world’s population could face shortages by 2030. At the same time, the transition to renewable energy is essential for reducing carbon emissions, with solar power playing a key role. The DESOLINATION project addresses these challenges by integrating concentrated solar power with advanced membrane processes fo
Pancreatic ductal adenocarcinoma (PDAC) is among the deadliest malignancies and potentially curable only with radical surgical resection at early stages. The tumor microenvironment has been shown to be central to the development and progression of PDAC.A better understanding of how early human PDAC metabolically communicates with its environment and differs from healthy pancreas could help improve
The increasing demand for energy-efficient and sustainable construction necessitates the need for building envelope designs that effectively balance moisture safety with sustainability. Improper moisture management in building envelopes can lead to severe consequences, including construction damage, decreased energy performance, and health risks associated with microbial growth. For instance, wate
With the rapid process of urbanization, water conflicts between different water use industries and areas are increasing. Therefore, China has implemented the three-cordons system of water resources management since 2012, when how to make more reasonable regulation of water resources became an urgent problem in most areas of China. In this study, taking the Yuanhe River Basin as an example, an inte
