We have calculated band-edge energies for most combinations of zinc blende AlN, GaN, InN, GaP, GaAs, InP, InAs, GaSb, and InSb in which one material is strained to the other. Calculations were done for three different geometries (quantum wells, wires, and dots) and mean effective masses were computed in order to estimate confinement energies. For quantum wells, we have also calculated band-edges f
The authors have previously shown that one-particle calculations of X-ray spectra in simple metals give very different results depending on whether the core hole is taken into account or not. Guided by experiment and the dynamical theory of X-ray spectra developed by Nozieres and DeDominicis (ND) (1969) the authors have, however, also established the rule that rather realistic spectra can be obtai
When distributed to different artefacts, the self appears in a multitude of shapes, characterized not only by its materiality but also by the necessity to preserve at least an illusion of a core self. The experience of a continuous evolution of these overlapping “selves”, many of which are materialized together with others’ overlapping selves, cannot be captured by traditional design approaches, n
Product concentrations may be estimated from gas analysis or calorimetric measurements. These techniques of analysis are fast, simple, and provide a continuous output. To check the accuracy of these estimations, the anaerobic ethanol formation of an industrial strain of the yeast Saccharomyces cerevisiae was selected as a test system. Cultivations were carried out as batch cultures with different
OBJECTIVE: To study the information gained by extending a well-established instrument of dependence/independence in activities of daily living with a self-rating of difficulty, and to illustrate the relevance and usefulness of this combined approach with cross-national data. DESIGN AND SUBJECTS: Cross-sectional survey study data collected with 1918 very old persons in 5 European countries. METHODS
Background: The ward atmosphere of psychiatric care units has a major impact on treatment and satisfaction for both patients and staff. The Ward Atmosphere Scale (WAS) was developed to capture the ward atmosphere in different psychiatric settings and is a well-established instrument for this purpose. However, there is need for an update and revision of the WAS. Aim: The aim of the present study wa
This study aimed to investigate the effect of dose reduction on diagnostic accuracy and radiation risk in digital mammography. Simulated masses and microcalcifications were positioned in an anthropomorphic breast phantom. Thirty digital images, 14 with lesions, 16 without, were acquired of the phantom using a Mammomat Novation (Siemens, Erlangen, Germany) at each of three dose levels. These corres
The present thesis investigated using the random forest machine learning algorithm for wind power forecasting. Meteorological prognoses for wind speed, wind direction, gust winds, and humidity were used. For historical data, wind minimum and temperature was also included. The results were evaluated using root means square error (RMSE), mean absolute error (MAE), normalized mean absolute error (NMA
Idag används stål eller titan som fixtur för benbrott. Dessa måste opereras in, och efter läkning opereras ut igen. En kandidat att ersätta dessa material är Magnesium, vilken naturligt och ofarligt bryts ned i kroppen så en andra operation inte behövs. För att kunna designa en magnesiumlegering vilken kan användas som implantat vid benbrott måste vi förstå hur nedbrytningsprocessen går till. FörMagnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0.3wt%Ca (ZX50). Z5 alloy was studied in two microstructural states, as-cast and as a supersaturated sol

This paper analyzes the impact of trade shocks on the female labor force. The EU enlargement of 2004 entailed a potential trade shock for Germany as trade barriers fell. With an increase in export opportunities and an increase in import competition, the enlargement could have an effect on the German labor market. The analysis is a quantitative approach of a panel data analysis and ranges between 1
Changes in farming practices over the past century have had negative influence on farmland biodiversity. Organic farming excludes most agrochemicals, such as inorganic fertilisers and synthetic pesticides, and can be an alternative to conventional farming. A recent meta-analysis indicates that there is on average 30% higher species richness on organically managed farmland compared to conventionall
Static analysis tools help developers find bugs, improve code readability, and ensure consistent style across a project. However, these tools can be difficult to smoothly integrate with each other and into the developer workflow, particularly when scaling to large codebases. We present Tricorder, a program analysis platform aimed at building a data-driven ecosystem around program analysis. We pres
This study is the first to estimate the effect of Agri-Environmental Schemes (AES) on nutrient runoff using abatement data and water samples on a large scale. This unique combination of data sources identifies all farms located upstream from a given water sampling site. By using watersheds that cover 91% of the Swedish land area and AES payments to 83% of Swedish farms, the study is almost a full
This thesis is a case study of the phenomena known as broken order in three Swedish libraries: two public libraries and one university library. While Swedish libraries often use the Swedish national classification scheme, SAB, or the international classification scheme, Dewey Decimal Classification, to shelve the majority of their material, parts of the stock are placed in alternative arrangements
Recent data on the prevalence and causes of hand eczema among healthcare workers in Sweden are lacking. Multidrug-resistant bacteria have necessitated improved hand hygiene and preventive measures. This has led to an increase in the use of disposable rubber gloves and hand disinfectants, which might influence the risk of hand eczema. Our aims were to identify healthcare workers with hand eczema; t
We present a novel approach to model the diffusion of a mutant in a geographical network. This is a key issue in the control of epidemics, since many diseases are transmitted by intermediate hosts that could be substituted with genetically modified organisms (GMOs) with a mutation that prevents them from spreading the pathogen. The main strength of our model lies in making analytically tractable t
Auger-electron spectroscopy (AES) has developed to a major tool for chemical identification and for characterization of solid surfaces. As first emphasized by Lander[1], it can also be used a spectroscopy for gaining information on occupied electron states and their interactions. However, AES gives a far less direct picture of the occupied states than does, for example, angle-resolved photoemissio
