The dark dimension provides a mechanism to resolve the cosmological hierarchy problem and assembles a colosseum for dark matter contenders. In a series of recent publications we investigated whether primordial black holes (PBHs) perceiving the dark dimension could constitute all of the dark matter in the universe. A key assumption of these investig...

Although mangroves provide many beneficial ecosystem services, such as blue carbon storage and coastal protection, they are currently under threat due to changes in climate conditions, such as prolonged drought exposure. Under drought conditions, evaporation exceeds precipitation and high soil salinities can lead to stunted growth and die-back. To ...

The number of artificial turf fields in cities has increased due to increased pressure on outside sport facilities caused by a higher population density. Downsides of these fields are changes in thermal conditions and decreased infiltration of rain. Artificial turf can reach very high surface temperatures leading to unfavourable playing conditions ...
Fluorescence-based methods (Laser Induced Fluorescence, Planar-LIF, 2 Colours LIF…) represent attractive means for studying liquids (flows or droplets) in a non-intrusive way. For example, the dependency of fluorescence on temperature makes possible the visualization of the entire temperature field within a droplet or a flow. The utilization of rat...
This work proposes an innovative model for multicomponent phase change in interface-resolved simulations. The two-phase system is described by a geometric Volume-Of-Fluid (VOF) approach, and considers multiple components in non-isothermal environments, relaxing the hypothesis of pure liquid droplets usually studied in the literature. The model incl...

This study investigates the influence of air exposure time on the erodibility of intertidal mud flats, emphasizing the role of evaporation in altering sediment strength and cohesion. Through a comprehensive approach combining laboratory experiments, fieldwork, and numerical modelling, it explores the dynamic interactions between sediment properties...

This contact line vicinity model is conceived as a subgrid model for the DNS of bubble growth in boiling. The model is based on the hydrodynamic multiscale theory and is suitable for the partial wetting case. On the smallest length scale (distance from the contact line) ∼ 100 nm, the interface slope is controlled by the Voinov angle. It is the stat...

The in-flight reduction of iron ore particles using an atmospheric pressure hydrogen plasma is investigated. Iron ore particles with a size less than 75 µm are aerosolized and carried with an argon-hydrogen (90%–10%) gas mixture through an atmospheric pressure microwave plasma. After the treatment, the collected particles are observed to follow thr...
Na Japonskem so se povprečne temperature zraka zaradi podnebnih sprememb povišale bolj kot v svetovnem povprečju. Na območju mesta Tokio poleg podnebnih sprememb na pojav višjih temperatur zraka vpliva intenziven mestni toplotni otok, ki povzroča spremembe v rabi energije in poleti negativno vpliva na človekovo udobje. V diplomskem delu smo opredel...
In the last two years the dark dimension scenario has emerged as focal point of many research interests. In particular, it functions as a stepping stone to address the cosmological hierarchy problem and provides a colosseum for dark matter contenders. We reexamine the possibility that primordial black holes (PBHs) perceiving the dark dimension coul...
