How mobile are protons in the structure of dental glass ionomer cements?
The development of dental materials with improved properties and increased longevity can save costs and minimize discomfort for patients. Due to their good biocompatibility, glass ionomer cements are an interesting restorative option. However, these cements have limited mechanical strength to survive in the challenging oral environment. Therefore, a better understanding of the structure and hydrat
Ultrasound as predictor of perinatal outcome
The aim of the work described in this thesis was to evaluate the value of ultrasound examinations of the amniotic fluid, umbilical cord and blood flow velocity waveform of the fetal and placental vessels as predictors of the perinatal outcome. In the first study, the amniotic fluid index (AFI) measured on admission to the labour ward was evaluated in low-risk pregnancies. An increased risk of ope
Predictive Control of Diabetic Glycemia
Diabetes Mellitus is a chronic disease, where the blood glucose concentration of the patient is elevated. This is either because of missing insulin production due to failure of the β-cells in the pancreas (Type 1) or because of reduced sensitivity of the cells in the body to insulin (Type 2). The therapy for Type 1 diabetic patients usually consists of insulin injections to substitute for the miss
Virtual Multi-link Propagation Investigation of an Outdoor Scenario At 300 MHz
The COST 2100 channel model has introduced the concept of common clusters to model multi-link MIMO characteristics. In this paper, a ray launching tool is used to analyze multi-ink propagation properties in an outdoor scenario at 300 MHz. It is shown that in a multi-link propagation scenario there are shared scatterers among the different links, which reflects the physical existence of common clus
A Peptide of Heparin Cofactor II Inhibits Endotoxin-Mediated Shock and Invasive Pseudomonas aeruginosa Infection.
Sepsis and septic shock remain important medical problems with high mortality rates. Today's treatment is based mainly on using antibiotics to target the bacteria, without addressing the systemic inflammatory response, which is a major contributor to mortality in sepsis. Therefore, novel treatment options are urgently needed to counteract these complex sepsis pathologies. Heparin cofactor II (HCII
Fractional excretion of IgG in idiopathic membranous nephropathy with nephrotic syndrome: a predictive marker of risk and drug responsiveness.
BACKGROUND: Treatment of idiopathic membranous nephropathy with nephrotic syndrome is still controversial. There is currently little known about the clinical use of renal biomarkers which may explain contradictory results obtained from clinical trials. In order to assess whether IgG-uria can predict the outcome in membranous nephropathy, we examined the value of baseline EF-IgG in predicting remis
Sweden, the swastika and Stalin: the Swedish experience in the second world war
Mäns våld mot kvinnor i nära relationer - och barn som upplever våld
This report presents a summary of Swedish research and knowledge concerning men’s violence against women in intimate relationships. It also discusses children’s experiences of this violence. Various theoretical perspectives on men’s violence are illustrated. A structural perspective on men’s violence is described using concepts like gender, power and normalization of violence. Some interactionist-

Co-occurrence of Risk Alleles in or Near Genes Modulating Insulin Secretion Predisposes Obese Youth to Prediabetes
OBJECTIVEParalleling the rise of pediatric obesity, the prevalence of impaired glucose tolerance (IGT) and type 2 diabetes (T2D) is increasing among youth. In this study, we asked whether the co-occurrence of risk alleles in or near five genes modulating insulin secretion (TCF7L2 rs7903146, IGF2BP2 rs4402960, CDKAL1 rs7754840, HHEX rs1111875, and HNF1A rs1169288) is associated with a higher risk o
Design of Robust PID Controllers with Constrained Control Signal Activity
This thesis presents a new method for design of PI and PID controllers with the level of control signal activity taken into consideration. The main reason why the D-part is often disabled in industrial control loops is because it leads to control signal sensitivity of measurement noise. A frequently varying control signal with too high amplitude will very likely lead to actuator wear and tear. For
Impact of glucose dosing regimens on modeling of glucose tolerance and β-cell function by intravenous glucose tolerance test in diet-induced obese mice.
Insulin sensitivity declines in overweight and obese individuals and, under normal conditions, insulin secretion adaptively increases which in healthy non-diabetic subjects maintains normal glycemia. This adaptation is best described by the disposition index derived from modeling of insulin and glucose data from an intravenous glucose tolerance testing (IVGTT). One caveat of the IVGTT is that basi
Continuum of care for frail elderly people: Design of a randomized controlled study of a multi-professional and multidimensional intervention targeting frail elderly people.
Background Frail elderly people need an integrated and coordinated care. The two-armed study "Continuum of care for frail elderly people" is a multi-professional and multidimensional intervention for frail community-dwelling elderly people. It was designed to evaluate whether the intervention programme for frail elderly people can reduce the number of visits to hospital, increase satisfaction wit
Kullabergs grottor : mellan istid och nutid, mellan humaniora och naturvetenskap
På Kullaberg finns ett drygt 30-tal kustnära grottor. Klippor och branta stup gör dem svåra att nå, från hav och från land. Hur har grottorna använts under de tusentals år som de funnits? Hur har bilden av grottmänniskor vuxit fram och har de överhuvudtaget funnits på Kullaberg? Arkeologiska utgrävningar och osteologiska djurbensanalyser från några av grottorna ger en del av svaren.

Global Optimization in Computer Vision: Convexity, Cuts and Approximation Algorithms
Computer vision is today a wide research area including topics like robot vision, image analysis, pattern recognition, medical imaging and geometric reconstruction problems. Over the past decades there has been a rapid development in understanding and modeling different computer vision applications. Even though much work has been devoted to modelling different problems, less work has been spent on
Changes in Prandial Glucagon Levels after 2-year Treatment with Vildagliptin or Glimepiride in Patients with Type 2 Diabetes Mellitus Inadequately Controlled with Metformin Monotherapy.
Objective - To determine if the dipeptidyl peptidase 4 inhibitor vildagliptin more effectively than the sulfonylurea glimepiride inhibits glucagon levels during meal. Research design and methods - Glucagon responses to a standard meal were measured at baseline and study endpoint (mean 1.8 years) in a trial evaluating add-on therapy to metformin with vildagliptin 50 mg bid compared to glimepiride u
Historical land-use and landscape change in southern Sweden and implications for present and future biodiversity
The two major aims of this study are (1) To test the performance of the Landscape Reconstruction Algorithm (LRA) to quantify past landscape changes using historical maps and related written sources, and (2) to use the LRA and map reconstructions for a better understanding of the origin of landscape diversity and the recent loss of species diversity. Southern Sweden, hemiboreal vegetation zone. The
Block copolymers combining semi-fluorinated poly(arylene ether) and sulfonated poly(arylene ether sulfone) segments for proton exchange membranes
A series of aromatic multiblock copolymers based on alternating segments of hydrophilic sulfonated polysulfone (PSU) and hydrophobic polyfluoroether (PFE) were prepared and characterized as proton exchange membranes. PSU precursor blocks were synthesized by polycondensation of dichlorodiphenylsulfone and resorcinol, and PFE precursor blocks were prepared by combining decafluorobiphenyl and isoprop
