Using the excess energy of charge carriers excited above the band edge (hot carriers) could pave the way for optoelectronic devices, such as photovoltaics exceeding the Shockley-Queisser limit or ultrafast photodetectors. Semiconducting nanowires show promise as a platform for hot-carrier extraction. Proof of principle photovoltaic devices have already been realized based on InAs nanowires, using

The potential devastation that a nuclear accident can cause to public health and the surrounding environment demands robust emergency preparedness. This includes gaining a greater knowledge of citizens’ needs in situations involving radiation risk. The present study examines cit-izens’ attitudes to a remediation scenario and their information and communication needs, using focus group data (n = 39

Ground-based, high-resolution spectrographs are providing us with an unprecedented view of the dynamics and chemistry of the atmospheres of planets outside the Solar System. While there are a large number of stable and precise high-resolution spectrographs on modest-size telescopes, it is the spectrographs at observatories with apertures larger than 3.5 m that dominate the atmospheric follow-up of

The study of the production of nuclei and antinuclei in pp collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. In this paper, the production of protons, deuterons and 3He and their charge conjugates at midrapidity is studied as a function of the charged-particle multiplicity in inelastic pp collisions at s=5

Background: SARS-CoV-2, the causal agent of COVID-19, enters human cells using the ACE2 (angiotensin-converting enzyme 2) protein as a receptor. ACE2 is thus key to the infection and treatment of the coronavirus. ACE2 is highly expressed in the heart and respiratory and gastrointestinal tracts, playing important regulatory roles in the cardiovascular and other biological systems. However, the gene

The response to atrial fibrillation (AF) treatment is differing widely among patients, and a better understanding of the factors that contribute to these differences is needed. One important factor may be differences in the autonomic nervous system (ANS) activity. The atrioventricular (AV) node plays an important role during AF in modulating heart rate. To study the effect of the ANS-induced activ

The present thesis explores how the tourist experience is re-articulated through the mediation of smartphones. I adopt the postphenomenological theory of mediation as the overarching ontological position, placing the role of technologies on an ontological level, as mediators of perception and experience. The new tourist that emerges from smartphone mediation is the smartphoned tourist, that is a t

Många filosofer verkar gilla tanken om att fakta är verkliga, man menar att fakta är verklighetens byggstenar. Wittgenstein identifierar ?världen? med ?totaliteten av fakta?, och enligt Russell så tillhör fakta den ?objektiva världen?. Jag kommer här inte heller att förneka att fakta är verkliga, så jag antar att fakta tillhör den objektiva världen.

In 2003 the deciding political council in Bromölla municipality requested that an overhaul on the committee and public administration structure should be conducted. In the report Bromölla was characterized as a traditional organization with a low degree of change. This case study will examine why the organization previously has been reluctant to change its structure and why they are willing to do

Abstract Why don't (some) regimes with formal democratic features undergo transition to democracy? Which are the internal dynamics of these regimes that can offer comprehension to this state of affairs? The main purpose of this thesis is to advance the above questions, and, on a lower level of abstraction, examine the case of Egypt. The Egyptian regime is characterized by, for instance, a mul

Populärvetenskaplig sammanfattning: Övergödningen av våra kustnära hav blev akut under 1980-talet, syrefria bottnar och giftiga algblomningar visade tydligt att något var mycket fel. Kväve, ett näringsämne, visade sig vara en av huvudorsakerna till dessa reaktioner i havet. De största kvävespridarna i Sverige var jordbruk och reningsverk. Avloppsvattenhanteringen behövde förändras och ett sätt attThe aim of this essay was to study the nitrogen flow in two willow plantations, at different locations in the south of Sweden, that were irrigated with sewage. The study was also performed to compare the differences in nitrogen flows between two years, 1998 and 1999. The study was made in three parts. First, the denitrification activity was measured using the acetylen inhibition method. Second the

Populärvetenskaplig sammanfattning: Krkonoše national park är beläget i Sudeterna vid gränsen mellan Tjeckien och Polen. Parken karakteriseras av stora variationer i altitud och ett mosaikliknande vegetationsmönster. Det komplexa landskapet medför svårigheter vid val av klassificeringsteknik och skala för produktion av tillförlitliga markanvändningskarteringar. Denna studie syftar i första hand tiThe Krkonoše National Park is located in the Sudetes mountain range at the Czech - Polish border. It is characterized by large variations in altitude and a mosaic vegetation pattern. The complex landscape raises the issues of appropriate classification techniques and scales. The first aim of this study is to produce a land cover map using 21 classes based on a rule-based classification system and

Populärvetenskaplig sammanfattning: Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra EuroThis work presents the results of a combined field measurement and modeling study of the soil moisture and surface energy balance at Ilstorp near Sjöbo in central Scania. The focus of the study is to investigate the water content of the upper few centimeters of a soil profile. Relevant meteorological variables were measured at the study site during April to June 1999. The field data were used to c
