Purpose: The purpose of this work was to evaluate the visibility of simulated lesions in 2D digital mammography (DM) and breast tomosynthesis (BT) images of patients. Methods: Images of the same women were acquired on both a DM system (Mammomat Novation, Siemens Healthcare, Erlangen, Germany) and a BT prototype system adapted from the same type of DM system. Using the geometrical properties of the

In this thesis, methods for efficiently determining stresses in laminated glass structures are developed and tested. The laminated glass structures comprise both bolted and adhesive joints. A recently developed finite element is suggested to be suitable for the modeling of laminated glass structures. The element is implemented and tested. It is proven by means of a simple test example that the ele

In this talk I present a short review of string hadronization, parton cascades, multiple scattering, final states, and underlying events.

The overall aim of this thesis was to study life satisfaction (LS) and factors associated to LS in the group aged 78 and above. As an aid in interpreting the findings, Baltes’ and Baltes’ theory of selective optimisation with compensation (SOC) was used. All four studies included the same studypopulation who were followed for three years in the study Good Aging in Skåne, a national, randomized, po

This contribution presents a novel offline dynamic multi-objective optimization framework for high-pressure liquid chromatographic (HPLC) processes in batch elution mode. The framework allows for optimization of general elution trajectories parametrized with piecewise constant control signals. It is based on a simultaneous method where both the control and state variables are fully discretized in

This paper examines the use of gradient based methods for extremum seeking control of possibly infinite-dimensional dynamic nonlinear systems with general attractors within a periodic sampled-data framework. First, discrete-time gradient descent method is considered and semi-global practical asymptotic stability with respect to an ultimate bound is shown. Next, under the more complicated setting w

(Schagatay E, Lodin-Sundstrom A. Abrahamsson E. Underwater working times in two groups of traditional apnea divers in Asia: the Ama and the Bajau. Diving and Hyperbaric Medicine. 2011;41(1):27-30.) Introduction: Traditional apnea diving for sea harvesting for a living continues in some communities in Asia, the outcome being dependent on the total underwater working time. We studied dive and surfac

To estimate the production of external ectomycorrhizal mycelia (EMM) in Norway spruce forests with varying nitrogen (N) and phosphorus (P) levels, and to relate this to the N retention capacity of ectomycorrhizal fungi (EMF) and N leaching. Seasonal changes in EMF production (in ingrowth mesh bags) and soil water N (in suction lysimeters) were analyzed after fertilization with N or N combined with

This special issue of Professions & Professionalism seeks to explain the transition of occupations from non-professions to professions and the conditions and causes that generate professions (i.e., the bases of professionalization). Empirically, we use the histories of the Swedish professions, positing that these histories have several close similarities (and, of course, differences) with thos

Granular GaAs(MnAs) layers with different Mn concentration and various layer thickness were grown by MBE method and subjected to annealing at 500A degrees C under ambient and enhanced hydrostatic pressure. Distinct influence of hydrostatic pressure applied during annealing on strain state of layers as well as on hexagonal MnAs inclusions was found. Pressure induced strain of inclusions is related

Increased PDGFRA signaling is an essential pathogenic factor in many subtypes of gliomas. In this context the cell surface expression of PDGFRA is an important determinant of ligand sensing in the glioma microenvironment. However, the regulation of spatial distribution of PDGFRA in glioma cells remains poorly characterized. Here, we report that cell surface PDGFRA expression in gliomas is negative

In this paper, a novel detection scheme for the monitoring of insect ecosystems is presented. Our method is based on the remote acquisition of passive sunlight scattering by two insect species. Procedures to identify rare events in remote dark-field spectroscopy are explained. We further demonstrate how to reduce the spectral representation, and how to discriminate between sexes, using a hierarchi

This thesis investigates Swedish intonation patterns and their interaction with word accent realisation in various pragmatic conditions, using German as a reference language. The point of departure is the wide-spread assumption that Swedish, as a language with a tonal word accent distinction, has a considerably smaller repertoire of nuclear intonation contours than German and other so-called inton

Our knowledge about acute promyelocytic leukemia (APL) patients is mainly based on data from clinical trials, whereas population-based information is scarce. We studied APL patients diagnosed between 1997 and 2006 in the population-based Swedish Adult Acute Leukemia Registry. Of a total of 3897 acute leukemia cases, 3205 (82%) had non-APL acute myeloid leukemia (AML) and 105 (2.7%) had APL. The in

Mammography screening can reduce breast cancer mortality. The aim of the present study was to investigate non-attendance in mammography screening in relation to different aspects of a women's social network, attitudes and cancer in close relations.

Immunocytochemistry for transactive response binding protein-43 (TDP43) was assessed in the granular cell layer of the dentate gyrus in 250 cases displaying hippocampal pathology identified by haematoxylin-eosin staining. 18%, nearly one in five displayed TDP43 immunoreactive pathology in the granular cell layer of hippocampus. This percentage increased to 43% when only subjects with hippocampal p

There is an increasing amount of data suggesting that there are inherent epidemiological and pathophysiological, as well as psychosocial differences between men and women with heart failure (HF). These differences may be so profound that they warrant differences in management and treatment. Furthermore women have been greatly underrepresented in clinical HF treatment trials. The major aim of the s
