Many insects depend on high-altitude, migratory movements during part of their life cycle. The daily timing of these migratory movements is not random, e.g. many insect species show peak migratory flight activity at dawn, noon or dusk. These insects provide essential ecosystem services such as pollination but also contribute to crop damage. Quantifying the diel timing of their migratory flight and
Understanding the structure-property relationship in electrocatalysts under working conditions is crucial for the rational design of novel and improved catalytic materials. This paper presents the Aarhus University reactor for electrochemical studies using X-rays (AUREX) operando electrocatalytic flow cell, designed as an easy-To-use versatile setup with a minimal background contribution and a uni
High humidity, high ash content and low heating values are the major disadvantages of using lignite without ant pretreatment. High moisture content and low energy density make some of the biomass resources disadvantages in direct energy production. In this thesis, the main aims to reduce the disadvantages of both sources and obtain fuel with different structural/physical properties by hydrothermal
In northern countries, the climate, and consequently the use of studded tyres and winter traction sanding, causes accumulation of road dust over winter and spring, resulting in high PM10 concentrations during springtime dusting events. To quantify the dust at the road surface, a method—the wet dust sampler (WDS)—was developed allowing repeatable sampling also under wet and snowy conditions. The pr
X-ray and neutron crystallography, as well as cryogenic electron microscopy (cryo-EM), are the most common methods to obtain atomic structures of biological macromolecules. A feature they all have in common is that, at typical resolutions, the experimental data need to be supplemented by empirical restraints, ensuring that the final structure is chemically reasonable. The restraints are accurate f
Immune function varies widely across humans. Biological sex is a key factor underlying human immune variability, with men presenting with more severe infections and increased cancer rates, while women exhibit higher vaccine responses and prevalence of autoimmunity. Intrinsic biological sex differences arise from varying contributions of chromosomal sex, and sex hormone sensing and downstream signa
Understanding tendon mechanobiology is important for gaining insight into the development of tendon pathology and subsequent repair processes. The aim of this study was to investigate how experimentally observed mechanobiological adaptation of rat Achilles tendons translate to changes in constitutive mechanical properties and biomechanical behavior. In addition, we assessed the ability of the mode
BACKGROUND: Volumetry of medial temporal lobe (MTL) structures to diagnose Alzheimer's disease (AD) in its earliest symptomatic stage could be of great importance for interventions or disease modifying pharmacotherapy.OBJECTIVE: This study aimed to demonstrate the first application of an automatic segmentation method of MTL subregions in a clinical population. Automatic segmentation of magnetic re
Albeit costly, flight allows birds to travel great distances in a short time, making it a highly effective mode of locomotion, especially during migration.1,2 Understanding how birds use energy during flight is essential for studying their flight ecology.3 To fly, birds flap their wings, accelerating surrounding air and generating flight forces, where the rate of energy added to the wake represent
Integrative lighting promoting circadian health has recently gained attention due to the increasing awareness of non-visual effects of light and advancements in lighting technology. However, reaching both visual and non-visual circadian targets in buildings may be challenging when considering energy use. Despite growing interest, most studies have focused on health benefits and individual design p
How mergers affect galaxy formation depends on both feedback processes, and on the geometry and strength of the mergers themselves. We introduce the PARADIGM project, where we study the response of a simulated Milky-Way-mass galaxy (M200c ∼ 1012 M at z = 0) forming in a cosmological setting to differing merger histories, using genetically modified initial conditions, each simulated with the VINTER
