This thesis concerns growth and characterization of gold-particle seeded nanowires of III-V semiconductor materials (III-V NWs). The nanowires were grown using metal-organic vapour phase epitaxy (MOVPE) and characterized by various microscopy techniques. In particular cross-sectional scanning tunnelling microscopy (XSTM) and cathodoluminescence microscopy (CL) were employed to investigate heterost
Anesthesiology is the medical specialty dedicated to the relief of pain and care of the surgical patient before, during and after surgery. Most of the work in anesthesiology is routine patient care, but because patients are sick and surgical procedures may develop in unexpected ways, anesthesiology by its nature often involves medical crises. In recent years, two concepts have gained increasing i
Cancer kan drabba vem som helst och kan ha sitt ursprung i många olika områden i kroppen. Antalet nya cancerfall ökar varje år, men vissa typer av cancer har bättre prognos än andra. Den vanligaste cancertypen i Sverige är prostatacancer och den drabbar framför allt äldre män. Prostatacancer har god prognos och det finns effektiva metoder att helt bota prostat- acancer om den behandlas i ett tidigPurpose: Recent developments in external radiotherapy and its utilization with artificial in- telligence (AI) enables advanced treatment plans for a range of different disease sites. By adapting to the anatomy of the day, target coverage can be ensured while sparing more healthy tissue. The purpose of this project was to study the feasibility and benefits of daily cone beam computed tomography (CB
In this study I have adressed the topic of citizen dialogue on the social network Facebook. I have conducted a study of how the city of Helsingborg use their Facebook page to communicate with the citizens and how they relate to the different rules, guidelines and policies that exist about dialogue and communication with the citizens on social media. The result of the study has shown that the city
Nowadays, is becoming increasingly frequent holding events in outdoor environments, involving a large number of people, even though these spaces were not designed from a safe prospective, in the way that safety is defined today. In such events, high density conditions is an ongoing issue, as the evacuation becomes very complex, due to the space design and the interaction among the pedestrians. It
Finansmarknaden genomgick stora förändringar innan 2000-talet och placeringsrådgivning kom att spela en allt viktigare roll. Tidigare hade det inte funnits lagstiftning på området, vilket man nu införde. Först kom Lag (2003:862) om finansiell rådgivning till konsumenter (FRL), därefter utfärdades ett EG-direktiv. Direktivet införlivades i svensk rätt genom Lag (2007:528) om värdepappersmarknaden (The Financial Market went through significant changes before the 2000’s and investments advisory played an increasingly important role. Earlier there had not been any legislation on the subject which there is now. The first legislation was the act of financial advisory and after that the Markets in Financial Instruments Directive, MiFID came from the EU. MiFID was implemented into Swedish law thro
Activation-induced cytidine deaminase (AID) is an enzyme and key component of both 15 class-switch recombination and somatic hypermutation, two mechanisms used by activated B 16 cells to diversify their antigen repertoire, as it catalyzes the deamination of deoxycytidines turning 17 them into deoxyuridines, introducing mutations in immunoglobulin genes. AID, however, can also 18 target enhancer re
Jag har intervjuat tre sångpedagoger för att förstå hur de balanserar sångteknik, personligt uttryck och röstideal i sångundervisningen. De forskningsfrågor jag sökt svar på är: Finns det ett eller flera röstideal som eftersträvas i sångundervisningen i allmänhet?; Vilket/ vilka är i så fall dessa röstideal?; Påverkar detta ”röstideal” det personliga uttrycket hos eleven och i så fall på vilket säThe vocal coache's task - A study of the balance between vocal technique, self expression and voice ideals. In my research I have been interviewing three vocal coaches to get an understanding of their way of balancing vocal techniques, self expression and voice ideals in their singing lessons. These are the research questions I sought answers to: Is there one or more voice ideals that is pursu
Background: Available evidence suggest that perceptions or ratings of the neighborhood, e.g. as being green, walkable or noisy, are important for effects on health and wellbeing, also after controlling for objective measures of identical or similar features. When evaluating effects of the perceived environment, it is important that measurement properties and the reliability of the environmental ra
Highly strained GaAs/GaP nanowires of excellent optical quality were grown with 50 nm diameter GaAs cores and 25 nm GaP shells. Photoluminescence from these nanowires is observed at energies dramatically shifted from the unstrained GaAs free exciton emission energy by 260 meV. Using Raman scattering, we show that it is possible to separately measure the degree of compressive and shear strain of th
OBJECTIVE-To determine the relative risk associated with DPA1 and DPB1 alleles and haplotypes in type I diabetes. RESEARCH DESIGN AND METHODS-The frequency of DPA1 and DPB1 alleles and haplotypes in type I diabetic patients was compared to the family based control frequency in 1,771 families directly and conditional on FILA (B)-DRB1-DQA1-DQB1 linkage disequilibrium. A relative predispositional ana
Background: Growing worldwide evidence shows that the experience of sexual coercion is fairly prevalent among young people and is associated with risky sexual behavior thereafter. The causal mechanisms behind this are unclear but may be dependent on specific contextual determinants. Little is known about factors that could buffer the negative effects of coercion. The aim of this study was to asses
As downscaling of semiconductor devices continues, one or a few randomly placed dopants may dominate the characteristics. Furthermore, due to the large surface-to-volume ratio of one-dimensional devices, the position of the Fermi level is often determined primarily by surface pinning, regardless of doping level. In this work, we investigate the possibility of tuning the Fermi level dynamically wit
The response of electric devices to an applied thermal gradient has, so far, been studied almost exclusively in two-terminal devices. Here we present measurements of the response to a thermal bias of a four-terminal, quasiballistic junction with a central scattering site. We find a novel transverse thermovoltage measured across isothermal contacts. Using a multiterminal scattering model extended t
