In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. The contact quality assessment is based on parameters extracted via electrical characterization performed mK temperatures in

Scale invariance and self-similarity in physics provide a unified framework for classifying phases of matter and dynamical properties near equilibrium in both classical and quantum systems. This paradigm has been further extended to isolated many-body quantum systems driven far from equilibrium, for which the physical observables exhibit dynamical scaling with universal scaling exponents. Universa

Small-scale production has come to the forefront of debates on just and sustainable transformations of food systems because of their potential contributions to communities’ livelihoods and food security. Small-scale freshwater aquaculture holds the promise to positively contribute to income generation and food security [1]. Yet, the evidence of the relationship between them is scarce, particularly

The potential of neutron powder diffraction in the location of hydrogen atoms in molecular materials and inorganic-molecular complexes is reviewed. Advances in instrumentation and data collection techniques that have made this field accessible are reviewed, along with a wide range of applications carried out by our collaboration investigating functional materials, hydrogen-containing minerals and

This report summarizes the classification systems for surface lining materials in Europe and Japan. There is also a part including a discussion on differences, similarities and possible ways to link the two different systems together. In June 1994, an important agreement was made between the member countries in the European Community. The agreement stated that all member countries should have the

Concussion is a frequent injury in many sports and is also common in para athletes. However, there is a paucity of concussion research related to para sport, and prior International Concussion in Sport (CIS) consensus papers have not substantively addressed this population. To remedy this and to improve concussion care provided to para athletes, the concussion in para sport (CIPS) multidisciplinar

We present the first in Poland, and among the first in Europe, cases of transcatheter implantation of the biological Sapien Edwards valve in the pulmonary position. The valves were implanted successfully without periprocedural complications in 2 patients with postoperative right ventricular outflow tract dysfunction.

Summary form only given. Spectra were recorded from a fluorescent light tube under a number of experimental conditions and using different spectroscopic techniques. The motivation of the work was to use spectroscopic techniques for plasma diagnostics purposes. The spectrometers used were a high resolution echelle based instrument and a Fourier transform spectrometer in Lund and a low-resolution in

Aim: This position paper focuses on healthy ageing for the frailest and institutionalized older adults in the context of the recent pandemic. The paper aims to identify and discuss hindering and promoting factors for healthy ageing in this context, taking both health safety and a meaningful social life into account, in a pandemic situation and beyond. Background: The recent COVID-19 pandemic has h

Maladaptive daydreaming is a distinct syndrome in which themain symptom is excessive vivid fantasising that causesclinically significant distress and functional impairment inacademic, vocational and social domains. Unlike normaldaydreaming, maladaptive daydreaming is persistent, compulsiveand detrimental to one’s life. It involves detachmentfrom reality in favour of intense emotional engagement wi

We investigated how the degree of autotrophy/heterotrophy and organism trophic position influenced the bioaccumulation of polychlorinated biphenyls (PCBs) in 10 benthic river food webs consisting of terrestrial detritus, periphyton, invertebrates, and age-0 brown trout (Salmo trutta) in southern Sweden. Concentrations of PCBs increased with trophic position, estimated from delta(15)N and delta(13)

TMJ autopsy specimens were studied macroscopically and arthrographically with respect to the disc position in the sagittal and the coronal planes. After single-contrast arthrography of the lower joint space, the specimens were cryosectioned. The arthrographic findings were correlated with the morphological findings. Anterior disc position was found in about two thirds and sideways disc displacemen

The study explores the validity of the media visibility thesis in a cross-country comparative framework, concentrating on the position of media outlets sympathetic or affiliated to the populist radical right parties in the public spheres in Hungary and Romania. The visibility of such media outlets in the public sphere is considered crucial in the context of discursive opportunities for political m

The issue of leaders’ influence has not received much attention in civil society studies, classical leadership literature on the voluntary sector and elite research. This article explores self-representations of the different kinds of status and influence among Italian third sector leaders. It is based on 35 interviews with the leaders of major Italian third sector organisations and on an analysis

Popular Abstract in Swedish Denna avhandling behandlar tillväxt av och elektriska mätningar på halvledande nanotrådar av indiumarsenid (InAs) och kombinationer av InAs och indiumfosfid (InP). En nanotråd är som namnet antyder en tunn solid tråd, som påminner om ett hårstrå fast med en diameter på typiskt 50 nm (en nanometer är en miljarddels meter, 10^-9 m) och längden kan vara allt från 100 nm upIn this thesis, semiconductor nanowires are studied from the point of view of growth and electrical properties. The growth of nanowires is done by chemical beam epitaxy (CBE), an ultra-high vacuum technique allowing a precise control of precursor deposition and low growth rates. In conventional epitaxy, growth is usually two or three- dimensional, depending on growth conditions and material combin
