The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promising routes are advanced coherent control and nonlinear spectroscopy schemes in the XUV energy range, yielding unprecedented spatial and temporal resolution. However, their implementation has been hampered by the experim

Dust growth is often indirectly inferred observationally in star-forming environments,theoretically predicted to produce mm-sized particles in circumstellar discs, and also presumably witnessed by the predecessors of the terrestrial meteoritic record. For those reasons it is believed that young gas giants under formation in protoplanetary discs with putative circumplanetary discs (CPDs) surroundin

Aims. We study the origin of tail-like structures recently detected around the disk of SU Aurigae and several FU Orionis-type stars. Methods. Dynamic protostellar disks featuring ejections of gaseous clumps and quiescent protoplanetary disks experiencing a close encounter with an intruder star were modeled using the numerical hydrodynamics code FEOSAD. Both the gas and dust dynamics were taken int

In the present work, an experimental investigation of convective heat transfer and pressure drop was carried out for the turning portion of a U-channel where the outer wall was equipped with ribs. The shape of the ribs was varied. The investigation aims to give guidelines for improving the thermo-hydraulic performance of a solar air heater at the turning portion of a U-channel. Both the U-channel

In this Letter, we have investigated 845 nm lasing generation in atomic oxygen, present in a lean methane-air flame, using two-photon pumping with femtosecond 226 nm laser pulses, particularly focusing on the impact of nanosecond repetitively pulsed glow discharges forcing on the backward lasing signal. Characterizations of the backward lasing pulse, in terms of its spectrum, beam profile, pump pu

Natural proteins must both fold into a stable conformation and exert their molecular function. To date, computational design has successfully produced stable and atomically accurate proteins by using so-called “ideal” folds rich in regular secondary structures and almost devoid of loops and destabilizing elements, such as cavities. Molecular function, such as binding and catalysis, however, often

Whey protein powder functionality is expected to be closely linked to both structure and properties of the proteins. It is essential that whey protein powders are easily dispersed and dissolved in order to fulfil the specified nutrient content and the functionality in the final product. Poor rehydration can cause challenges on an industrial level as well as for the consumers.

This thesis deals with older persons on the move and their access to cross-border healthcare in the European Union. The number of persons crossing borders within the EU has increased exponentially in recent decades. Free movement has been at the core of the European integration project from its early days. Although it was originally intended to apply only to those who were economically active, theThis thesis deals with older persons on the move and their access to cross-border healthcare in the European Union.

We study the chemical evolution of Zr, La, Ce, and Eu in the Milky Way discs and bulge by means of chemical evolution models compared with spectroscopic data. We consider detailed chemical evolution models for the Galactic thick disc, thin disc, and bulge, which have been already tested to reproduce the observed [α/Fe] versus [Fe/H] diagrams and metallicity distribution functions for the three dif

The 2014 Êzîdî Genocide caused a rupture in the social fabric of the Iraqi religious Êzîdî minority. A search for meaning in the aftermath of violence has caused a group of Şingalî poets to reconstruct memories of the past through their narration in Arabic prose poetry. A narrative analysis has been used on a selection of poems written and interviews conducted with five poets. I investigate their

Today, as a result of fast-paced societal transformations, many small towns face severe developmental challenges and an uncertain future. Departing from the broader theory of developmental disequilibrium, we launch the concept of urban hibernation to explain the process of periodic small-town regress. The concept—along with its key stages and turning points—is presented to the background of urbani

Hur kan det komma sig att faktaresistensen exploderar i takt med coronautbrottet? Enligt sociologiprofessor Mikael Klintman är svaret glasklart. Vet du bäst själv? Läs inte det här.

The use of public demand to spur innovation has recently seen a very significant in-crease in political support. Such a policy promises improvement of public services on all state levels, combined with a contribution to innovation dynamics. It has become clear that strong efforts are needed to mobilise procurement at all state levels for inno-vative markets. These efforts need to be based on a bet
