Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures
Detta arbete är en personlig analys med målet att stegvis få kunskap kring och slutligen definiera den musikaliska rösten hos artisten som filmkompositör. Med hjälp av en musikanalytisk metod, en undersökning och reflektioner är målet att kartlägga de huvudsakliga musikaliska och icke-musikaliska aspekterna som bygger den konstnärliga stilen.This work is a personal step by step analysis with the goal of defining the musical voice of the artist as a film composer. With the use of a music analytical method, research and reflections the aim is to map out the major musical and non-musical aspects that build the artistic style.
En studie i arkitektoniska kvaliteter i tid och rum Detta projekt är något av en lågmäld hyllning till en typ av arkitektur som utgör en bas i många av våra städers yttrekantsområden. Byggnader som inte från början var menade att göra något väsen av sig, men som i en senare kontext står ut och attraherar. Ambitionen är att undersöka vilka komponeneter som genrerar dessa platser; som på något sät
Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissio
The concept of this research is that by applying the proposed method, the trajectory of drift into failure can be made visible. The method itself consists of two sequential steps. For research purposes a third step is added. The first step is constructing a phased narrative, consisting of all the changes that have taken place within a particular organisational process subject to research. What has
This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13.7 keV, generated by the synchrotron radiation, impinges the material, and fluorescent X-ray spectra
Fracture risk in osteoporosis is increased and osteoporosis is the most common metabolic bone disease and treatment is expensive. Osteoporosis is diagnosed by measuring Bone Mineral Density (BMD), which does not consider other factors such as bone geometry or architecture. 3D-based models can predict risk fracture better than BMD, but they require 3D computed tomography. Solution of the problem is
Determining how proteins interact with each other to form complexes is very important for understanding both disease and cellular functions, but experimentally determining the structures of these complexes is both tedious and slow, which is why a great number of protein-protein docking algorithms have been developed to predict them. To this day, conformational changes in protein backbones have bee
This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning acros
Increasing global temperatures have been shown to advance the breeding phenology of migratory birds, not least in temperate regions, causing birds to adapt the timing of other life-history events such as molt. At high latitudes, summers are shorter, and the birds must complete their post-breeding molt in the few weeks available before the conditions in the breeding site become unfavorable. I exami
Animal migration is a widespread phenomenon that has evolved repeatedly in a diverse set of taxa. To cope with migration, individuals express a large variety of specialized behavioural adaptations, that rely on efficient sensory systems for extraction of relevant external information. Many behaviours are visually guided, such as foraging and predator avoidance, and most migratory animals possess e
Vägarna i Sverige är totalt cirka 57 000 mil långa. Av dessa anses cirka 43 000 mil vara tillhöriga enskilda väghållare, det vill säga någon annan än offentliga aktörer så som stat eller myndighet. Vägar har länge haft en stor betydelse ur ett flertal aspekter och det har alltid funnits ett stort intresse av att vidhålla ett gott infrastruktursystem. Bestämmelser om vägar fanns det redan i de äldThe aim of this paper is to improve the management of joint facilities and private roads. This was done by identify and investigat different problems connected to the private road organisations, formed through the regulation of joint facility and associations connected to them. One aspect of the investigation was if the area of included land connected to one joint facility had grown in size. By st
Bakgrund: Med anledning av Barnkonventionens inkorporering i svensk lag är det idag högst aktuellt att undersöka och diskutera hur barn upplever att de ges möjlighet att vara delaktiga i sin vård. Barns delaktighet bygger på en god kommunikation och relation till hälso- och sjukvårdspersonal. Trots föreskrifter om att barn bör vårdas på avdelningar avsedda och anpassade till dem, förekommer det re
Den här studien undersöker en grupp musikelevers improvisatoriska val över dominantackord som leder till tonika i improvisationer över II V I-progressioner i dur. Studiens fokusområde motiveras av den höga andel II V I-progressioner som används som musikaliska byggstenar i genrer där improvisation förekommer i hög grad. Även om det inte ligger inom räckhåll för den här studien att undersöka kausalThis study focuses on a group of music students’ improvisational choices over the Vchord leading to the I-chord when improvising over major II V I chord progressions. The raison d'etre for this study is the high number of II V I-progressions being used as musical building blocks in genres that have improvisation as an integral part. Although it was not within the scope of this study to establi
Bakgrund: Människors livsstil och hälsa innan befruktning kan påverka graviditet, barnafödande och fostrets utveckling och välmående varför prekonceptionell hälsa och vård är viktig för alla individer. Barnmorskan arbetar med reproduktiv, perinatal och sexuell hälsa men möter sällan pojkar och unga män i sitt arbete. Skolsköterskan har därför föreslagits som lämplig att informera pojkar och unga m
Rapidly changing environments across the globe pose challenges for organisms to either adapt or risk extinction. High rates of gene flow are expected to prevent populations from adapting to their local ecological environments, but an increasing number of studies show that even at small geographical scales, natural or sexual selection can counteract the homogenizing effect of gene flow. Here I show
