Aims. We study how diffuse interstellar bands (DIBs) measured toward distance-distributed target stars can be used to locate dense interstellar (IS) clouds in the Galaxy and probe a line-of-sight (LOS) kinematical structure, a potentially useful tool when gaseous absorption lines are saturated or not available in the spectral range. Cool target stars are numerous enough for this purpose. Methods.
Popular science summary Ecosystem seasonality in climate models Climate change has a major effect on the timing, intensity and duration of seasonal events in Earth´s ecosystems. These changes may remain undetected when analyzing them on an annual scale, as current climate models usually do. Therefore it is necessary to investigate the impact of ecosystem seasonality on climate processes to impr
Abstract Over 1000 published species which are largely heterogenous in morphology were formerly grouped in the lichen genus Caloplaca s. lat. (Ascomycota, eloschistaceae). Although there is no complete monograph of the genus, many taxonomic studies have focused on specific geographical regions. Although a number of these studies have focused on species that exist in California, samples of putativ
The forest contributes multiple services, among others renewable materials, carbon sequestration, and recreational value. This thesis studied the effects on forestry stemming from the revised Land Use, Land Use Change, and Forestry regulation. The question is how reduced logging, which is in line with the new regulation, affects social welfare when incorporating the benefits of ecosystem services.
In the face of climate change, a fast global switch from fossil fuels to renewable energy is imperative. In the Netherlands however, prospects for such a switch are bleak. With 6% renewables its progress is lagging, and vested interests hold back change. The transition is failing. This thesis provides an alternative, by identifying a new solution to the sluggish transition, a new agent that could
The fight against malaria in Kenya is tightly connected to gender inequalities. The traditional gender roles in some households create exposure patterns that affect the most vulnerable groups: pregnant women and children. Current political strategies to prevent malaria in pregnancy rely on community health volunteers (CHVs), who fulfil a crucial role as implementers of malaria policies on communit
Climate change is an issue that can no longer be ignored and actions are taken all over the world in order to prevent the effects from becoming too severe. The energy system is transitioning towards more renewable energy sources and wind power has an important role in this development. The penetration of wind power in a lot of countries all over the world has increased rapidly during the last deca
Nanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements. An alternative to conventiona

De senaste åren har upphovsrätten fått mycket uppmärksamhet eftersom den digitala utvecklingen och framväxandet av Internet gjort det möjligt att snabbt och utan kvalitetsförlust lagra och överföra stora mängder ljud, bild och text. Denna överföring är inte sällan olovlig och det sker idag omfattande upphovsrättsintrång över Internet. I dessa intrång är det i huvudsak tre olika aktörer som är inblIn recent years, copyright law has been given much attention since the digital development and the emergence of the Internet made it possible to quickly storage and transfer large amounts of audio, images and text without loss of quality. The transfer is often illegal and there is a widespread copyright infringement going on in the Internet environment. In these infringements there are three main
Since the beginning of African decolonisation in the mid-twentieth century, many newly independent countries struggled to embark upon a path of sustained economic growth to raise their populations out of poverty. One of these countries is Tanzania. Surrounded by the Great Lakes on the west and bordering the Indian Ocean to the east, Tanzania is the fifth-most populous country in Africa. It is also
Objective: The aim of this study was to evaluate changes in transcutaneous oxygen pressure (tcpO2) and systolic toe pressure (TP) during endovascular intervention. Methods: This was a single centre prospective, non-randomised, observational feasibility study. Patients with chronic limb threatening ischaemia (CLTI) due to infrainguinal disease scheduled for endovascular treatment were included betw
Establishing a solid chronological framework for Arctic marine sediments is a critical first step towards glacial and palaeoceanographic reconstructions. However, this has historically been more challenging than elsewhere in the world, and often results in core chronologies and subsequent paleoenvironmental reconstructions being questioned and overturned. Optically stimulated luminescence (OSL) da
Part 1: From Brain to GutThe brain is an organ with a high energy requirement. To meet this demand, the brain needs a continuous and well-regulated blood supply. In situations where the brain, or parts of the brain, does not receive sufficient blood flow injury arise. This condition, commonly known as cerebral ischemia, is prevalent in today's society. In 2015, more than 6 million people died from
SPI1 (also known as PU.1) is a dominant but transient regulator in early T-cell precursors and a potent transcriptional controller of developmentally important pro-T-cell genes. Before T-lineage commitment, open chromatin is frequently occupied by PU.1, and many PU.1 sites lose accessibility when PU.1 is later down-regulated. Pioneering activity of PU.1 was tested in this developmentally dynamic c
The content of minerals and dietary fibre in different fractions of oats was investigated. The oat kernel (pericarp, testa, germ, aleurone, endosperm), accounting for 70 % of the oat seed, had a dietary fibre content of 11·5 g/100 g (dry weight basis); of this 23 % was soluble fibre components, mainly β-glucans. In contrast to most other cereals the amount of soluble fibre was distributed througho
Background: Precision prevention involves tailoring interventions to the unique characteristics of a group or individual to maximize their effectiveness. In this study, we examined the role of participant characteristics in the effectiveness of lifestyle interventions to optimize gestational weight gain (GWG). Methods: We searched Medline, Embase, and PubMed, from inception up to March 2025, to id
The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also hinge on male investment strategies in sexually cannibalistic species. In many spiders, males perform energetically costly courtship rituals to increase acceptance by females and minimise the risk of sexual cannibalism. However, due to sperm competition, males may invest less energy whe
