The topic of this thesis is technology and experimental studies of electron transport in Indium Arsenide (InAs) nanowires and InAs nanowire junctions. The aim of this work has been fabrication of nanoelectronic devices which have possibilities for future nanoelectronics. The first chapter gives an introduction to modern electronics and some important concepts. The second chapter presents an overvi

Popular Abstract in Swedish Nätverk av nervtrådar påvisades kring koronara artärer och vener från marsvin och människa. Medelst immunhistokemiska metoder demonstrerades olika signalsubstanser i anknytning till dessa nervtrådar och i olika delar av kärlväggen (endotelet, media, adventitia), och det påvisades hur vissa av dessa substanser var lokaliserade i samma vesikler av ovan nämnda nervtrådar. A network of perivascular nerve fibres was demonstrated in coronary arteries and veins from guinea-pig and man. Nerve fibres displaying immunoreactivity to neuropeptide Y (NPY) had a distribution pattern similar to those containing immunoreactivity to tyrosine hydroxylase. Immunoreactivity to substance P and calcitonin gene-related peptide (CGRP) occurred in the same varicose nerve fibres, which w

Popular Abstract in Swedish Av de omkring 45 000 svenskar som årligen drabbas av cancer kommer ungefär hälften att botas, ofta med strålning som en del av behandlingen. Syftet med strålterapi är att oskadliggöra tumören, men utan att skada omgivande vävnad. Idealt vill man att stråldosen ska vara mycket hög i tumören, samtidigt som den är obefintlig i vävnaden runt omkring. Strålskador på frisk väIn many radiotherapy applications, true three-dimensional dosimetry with good spatial resolution that can be achieved in a single measurement would be of great value. Polymer gel dosimetry fulfils many of the demands on such a system. In this study, methods to facilitate the implementation of gel dosimetry have been investigated. A new type of polymer gel, for which the response to absorbed dose i

At first sight, international law seems to uphold both state sovereignty and individual sovereignty. The existence and autonomy of a state are secured by the obligation on other states to respect its territorial integrity and the prohibition on intervening in other states’ domestic affairs. At the individual level, internationally guaranteed human rights serve comparable functions: they secure a m

In this analysis of the retold experiences of 27 survivors of the war in northwestern Bosnia, the aim is to describe the informants’ portrayal of “victimhood”, “forgiveness” and “reconciliation” as a social phenomenon as well as analyzing the discursive patterns that contribute to constructing the category “victim” and “perpetrator”. When, after the war, different categories claim a “victim” statu

To study the development of physical health and some neuromotor functions in anorexia nervosa (AN) 51 individuals (48 females, three males) with a mean AN onset of 14 years, recruited after community screening, were followed prospectively together with 51 age-, sex-, and school-matched individuals without AN (controls). About 10 years after AN onset, all individuals were examined in respect of phy

Yeasts are unicellular fungi exhibiting a huge diversity of life styles and physiologies and their evolutionary span exceeds the one between mammals and unchordates. The recent advances in genome sequencing and comparative genomics accelerated genomic, evolutionary and physiological studies of yeasts, making them a very promising model to study eukaryotic cell, and also deepened our understanding

Popular Abstract in Swedish Omgivningens temperatur är kanske en av de faktorer som i allra störst utsträckning påverkar djur och deras livsmiljö. Detta bottnar givetvis till stor del i temperaturens effekt på naturen. Betänk till exempel årstidsväxlingarna; att vintern blir till vår, och att hösten (i samband med de första snöfallen) allt mer skrider mot ännu en kall och vit vinter bestäms och reTemperature is a property of profound matter in all aspects of animal life, affecting both individual energy budgets and the environments in which animals reside. Thus, a proper understanding of the effects of temperature variation is instrumental in understanding not only animal form and function, but also the structure and dynamics of wild populations. Accordingly, the aims of this thesis were t

Popular Abstract in Swedish Hur begreppet religion kan klargöras eller definieras är en mycket omtvistad fråga inom åtskilliga akademiska discipliner. Två huvudsakliga negativa tendenser är märkbara inom gängse och aktuell teoribildning. För det första har det framkastats en mängd divergerande definitionsförslag under årens lopp. Detta har bland annat lett till en teoretisk uppgivenhet inför uppgiIt is a contested question in contemporary theories of religion whether the concept of religion can be defined in a sound way or not. Many theorists maintain that a universal but delimiting definition is impossible. In this study, by contrast, it is argued that a conceptual analysis of religion that holds universally is perfectly possible because the following thesis can be seen as a necessary and

Understanding the relationship between concepts and experience seems necessary to specifying the content of experience, yet current theories of concepts do not seem up to the job. With Peter Gärdenfors's conceptual spaces theory as a foundation and with enactivist philosophy as inspiration, we present a proposed extension to conceptual spaces theory and use it to outline a model of the emergence o

Popular Abstract in Swedish Utvecklandet av helt nya baspolymerer för tillverkning av massprodukter förväntas i framtiden vara begränsad p.g.a. för höga investeringskostnader. En av de mest tydliga trenderna inom polymerindustrin idag är istället den ökande betydelsen av polymerblandningar. Kombinationer av två eller flera polymerer som bildar fasseparerade strukturer i blandning ger ofta materialOne of the main trends in the polymer industry today is the increasing importance of polymer blends. Combining two or more immiscible polymers in a polymer blend often leads to multi-phase materials with desirable properties. The typical poor morphological stability and low interfacial adhesion in these blends can be eliminated by adding compatibilizing graft copolymers. Well-defined graft copoly

In what has been seen as an age of increasing bureaucratisation, did it matter who was close to the monarch? Since the monarch embodied supreme wordly power, the way in which daily life at court was organised was of great importance. One function of the early modern court was, in the words of Geoffrey Elton, to act as a point of contact between monarch and élite. I have chosen to test this hypothe
