In this thesis, the electronic structure and optical properties of semiconductor nanostructures are studied theoretically. Three types of nanostructures have been studied, silicon nanocrystals, free-standing III-V nanowires and free-standing GaAs/AlGaAs nanowire superlattices. The calculations have been carried out using an atomistic, empirical tight-binding approach. Silicon nanocrystals have at
Objective: To describe beliefs about health and illness among foreign-born people with diabetic foot ulcers that might affect selfreported self-care and health-care seeking and to study whether there are dissimilarities related to origin. Method: Qualitative descriptive study. Semi-structured interviews with people aged 38-86 years; 13 born in European and 13 in non-European countries (all except
Electrical machines, chokes and induction heaters are found in most homes,offices and factories all over the world. They are used to create movement, filtrate the power or to generate heat. A typical unit consist of a coil and a flux conductor material. Some of the materials have been established for over 100 years, while others are only a couple of decades old.A new flux conductor material has be
Purpose: Muda is a Japanese term literally meaning futility, uselessness, idleness, superfluity, waste, wastage or wastefulness. The term was introduced by the Japanese engineer Taiichi Ohno of Toyota Motor Corporation in the 1960s. Therefore, reducing and minimizing Muda is an effective way to increase the operational efficiency and productivity of an organization’s processes. In turn, the techni
Background: Despite the fact that heart failure and chronic obstructive pulmonary disease (COPD) often exist together and have serious clinical and economic implications, they have mostly been studied separately. Our aim was to study prevalence of coexisting heart failure and COPD in a Swedish population. A further goal was to describe levels of other comorbidity and investigate where the patients
A measurement of elastic deeply virtual Compton scattering gamma*p --> gamma p using e(+) p and e(-) p collision data recorded with the HI detector at HERA is presented. The analysed data sample corresponds to an integrated luminosity of 306 pb(-1), almost equally shared between both beam charges. The cross section is measured as a function of the virtuality Q(2) of the exchanged photon and the ce

According to efficient market theory, all publicly available information is reflected in asset prices. In its semi-strong form, fundamental analysis cannot be used as a method to generate an abnormal return. Implying that abnormal return can only be achieved by incurring a higher level of risk. Joel Greenblatt (2006) shows that by applying simple fundamental analysis and ranking companies based on
Early results of mitral valve replacement were reviewed in 336 unselected patients, 261 without and 75 with concomitant coronary artery bypass grafting (MVR and MVR + CABG groups). Early (less than 30 days) mortality was 7% in the MVR and 16% in the MVR + CABG group, with cardiac failure as the dominant cause. In multivariate analysis, the variables most strongly related to early mortality were co
Purpose: The present study was performed as part of an epidemiological study, the Inter99 Eye Study. The aim of the study was to describe refractive errors and visual acuity (VA) in a suburban Danish population.Methods: The Inter99 Eye Study comprised 970 subjects aged 30–60 years and included a random control group as well as groups at high risk for ischaemic heart disease and diabetes mellitus.
This work investigates the multi-scale dynamics of the combustion system in a lean-burn spark ignition natural gas engine using different gas injection timings (GIT). The in-cylinder pressure time series are measured, and the indicated mean effective pressure (IMEP) time series are calculated. The influence of GIT on the combustion system is investigated through wavelet analysis, multi-resolution
Humans have an irresistible inclination to coordinate actions with others, leading to species-unique forms of cooperation. According to the highly influential Shared intentionality theory (SITh), human cooperation is made possible by shared intentionality (SI), typically defined as a suite of socio-cognitive and motivational traits for sharing psychological states with others, thereby enabling ind
This article is about psychiatric patients’ life stories. I explore how best to handle patient narratives in the history of medicine and, more specifically, in the history of psychiatry. By applying a narrative and phenomenological analysis – seldom used in historical studies of psychiatry and psychiatric care – the aim is a new understanding of patient stories both as historically situated and as
Purpose: To evaluate inter- and intrarater reliability, of the Eating and Drinking Ability Classification System (EDACS) for children and adults with cerebral palsy (CP) in Sweden. Methods: Four speech and language pathologists rated EDACS from videos of 30 individuals with CP, 3 to 62 years, (mean 21 y, 10 m, SD 18 y, 6 m), six at each level of the Gross Motor Function Classification System (GMFC
Syftet med denna avhandling är att undersöka användningen av naturrättsligt språkbruk i de danska agrarreformerna, cirka 1750-1800. Detta görs genom en social kontextualisering som fokuserar på de sprickor som fanns i det danska samhället före och under reformperioden. Jag hävdar att dessa huvudsakligen utgjordes av interna materiella skillnader inom den danska jordägande eliten, inklusive deras o
Context. Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for nine selected regions in the sky. A new software pipeline exploits these Service Interface Function (SIF) images of crowded fields (CFs), making use of the availability of the full two-dimensional (2D) information
There is a need of problematizing taken for granted assumptions in the conceptualization of collaborative housing when attempting to link collaborative housing and social integration. What are the difficulties and opportunities that migrants and non-migrants face in accessing collaborative housing projects? Addressing such type of questions will help to capture exclusionary processes affecting old
The main concerns associated with epilepsy during pregnancy consist of maternal and fetal risks from uncontrolled seizures, and harmful effects of the treatment on the development of the offspring. Although seizure control is maintained in the majority, worsening occurs in a fraction of childbearing women with epilepsy. As multiple factors associated with pregnancy may have a negative impact on ep
Objective: We aimed to test whether region-specific factors, including spatial expression patterns of the tau-encoding gene MAPT and regional levels of amyloid positron emission tomography (PET), enhance connectivity-based modeling of the spatial variability in tau-PET deposition in the Alzheimer disease (AD) spectrum. Methods: We included 685 participants (395 amyloid-positive participants within
