An independent in vivo dose verification procedure for IMRT treatments of head and neck cancers was developed. Results of 177 intracavitary TLD measurements from 10 patients are presented. The study includes data from 10 patients with cancer of the rhinopharynx or the thyroid treated with dynamic IMRT. Dose verification was performed by insertion of a flexible naso-oesophageal tube containing TLD

Willingness-to-pay (WTP) techniques are increasingly being used in the healthcare sector for assessing the value of interventions. The objective of this study was to estimate WTP and its predictors in a randomized controlled trial of a lifestyle intervention exclusively targeting Middle Eastern immigrants living in Malmö, Sweden, who are at high risk of type 2 diabetes. We used the contingent valu

Alejo Carpentier (1904-1980) is one of the most distinguished writers in Latin American literature and numerous studies have delved into his literary works. However, very little is known about his private life and family background apart from the facts that he chose to reveal about himself. Indeed, several of these “facts” have turned out to be false. This thesis sets out to examine whether a hidd

Bergh considers the relationship between migration and interpersonal trust in the European Union. Interpersonal trust, Bergh avers, is an important foundation for a well-functioning society. The question is how interpersonal trust is affected by increased migration in countries with differing levels of trust. Bergh shows that migrants from low-trust countries who move to high-trust ones show highe

Artistic research is a comparatively new academic field, displaying multiple epistemological and methodological approaches. Through a concrete exemplification, this article studies how knowledge formation and learning may take place in artistic fields by way of intermedially borrowed concepts. The prominent use of the concept of ’musicality’ as a prestige word in the field of spoken theatre is inv

Monte Carlo simulations of linear, weak polyacids and explicit simple ions have been performed in a spherical cell model to study the shift in the apparent dissociation constant. The simulations are performed in a canonical ensemble with the apparent dissociation constant calculated in a procedure based on Widom’s particle-insertion method. The effects of model parameters are discussed, for exampl

Few studies have examined the association between individual-level socioeconomic status and access to kidney transplantation. This study aims to investigate the association between predialysis income and education, and access to (i) the kidney waitlist (first listing), and (ii) kidney transplantation conditional on waitlist placement. Adjustment will be made for a number of medical and

The site–site Ornstein–Zernike equation with a simple mean spherical closure is used to study electrostatic interactions of proteins. Using a Debye–Hückel approximation for the correlation functions of the bulk electrolyte and a simple basis expansion for the protein–salt direct correlation functions, we obtain a very simple variational expression for the electrostatic component of the excess chem

Monte Carlo simulations have been performed for two simple models of a titrating polyelectrolyte: (i) a rigid rod and (ii) a freely jointed chain. Both models have fixed bond lengths, and the polyelectrolyte charges interact through a screened Coulomb potential. Chains consisting of 80-1000 monomeric units have been studied at three salt concentrations: 0.001, 0.01, and 0.1 M. Conformational prope

Introduction: The aim of this study was to evaluate if magnesium deviations correlate with higher 180 day overall mortality or increased morbidity, compared to controls. Methods: We conducted a retrospective study on 5369 patients with 22,003 magnesium values treated at the Adult Intensive Care Unit at Skåne University Hospital, Lund, Sweden during 2006-2014. The patients were retrospectively divi

III-V nanowires are candidate building blocks for next generation electronic and optoelectronic platforms. Low bandgap semiconductors such as InAs and InSb are interesting because of their high electron mobility. Fine control of the structure, morphology, and composition are key to the control of their physical properties. In this work, we present how to grow catalyst-free InAs1-xSbx nanowires, wh

The need for indium droplets to initiate self-catalyzed growth of InAs nanowires has been highly debated in the last few years. Here, we report on the use of indium droplets to tune the growth direction of self-catalyzed InAs nanowires. The indium droplets are formed in situ on InAs(Sb) stems. Their position is modified to promote growth in the 〈11-2〉 or equivalent directions. We also show that in

Controlling the growth direction of nanowires is of strategic importance both for applications where nanowire arrays are contacted in parallel and for the formation of more complex nanowire networks. We report on the existence of tilted InAs nanowires on (111)B GaAs. The tilted direction is predominantly the result of a three-dimensional twinning phenomenon at the initial stages of growth, so far

Pedagogical material for children with visual impairment is often created by hand and in very small series. Although there are a lot of opportunities and there are more and more applications of how to use 3D printers in society, it's unusual that they are used systematically to create tactile material for school pupils that have a visual impairment.This report presents in a comprehensive way how t

[Context and motivation]} Internet of Things (IoT) is becoming common throughout everyday lives. However, the interaction is often different from when using e.g. computers and other smart devices. Furthermore, an IoT device is often dependent on several other systems, heavily impacting the user experience (UX). Finally, the domain is changing rapidly and is driven by technological innovation. [Que

Background: Transient ischemic attacks (TIA) indicate an increased risk of stroke, one of the leading causes of death and disability worldwide. In order to prevent stroke, our knowledge of diagnosis, demographics, risk factors, investigations, and treatment of patients with TIA needs to be improved.Aims: The aims of this thesis were to validate data and diagnoses in the Riksstroke TIA module (Riks

BACKGROUND: Current guidelines for accessing graphs non-visually are based on giving access to underlying tabular data and reading the values one by one. When data sets are large, it becomes impossible to get an overview.OBJECTIVE: This work presents a proof-of-concept of automated audio description of data sets up to 100 data points that can be used by persons with visual impairment or persons wh
