Atrial fibrillation (AF) and co-morbidity in elderly. A population based survey of 85 years old subjects

The occurrence of AF increases sharply with age. The aim of this study was to explore and compare prevalent co-morbidity and self-estimated health-related quality of life (HRQoL) in subjects with AF versus subjects with sinus rhythm or pacemaker in 85 years old subjects. We analyzed data from a population of 336 eighty-five years old subjects participating in the Elderly in Linkoping Screening Ass

Estimating potential forest NPP, biomass and their climatic sensitivity in New England using a dynamic ecosystem model

Abstract in UndeterminedAccurate estimation of forest net primary productivity (NPP), biomass, and their sensitivity to changes in temperature and precipitation is important for understanding the fluxes and pools of terrestrial carbon resulting from anthropogenically driven climate change. The objectives of this study were to (1) estimate potential forest NPP and biomass for New England using a re

This dissertation deals with the morphological development in written L2 French by Swedish learners. The thesis presents a detailed analysis of number marking and agreement in NPs and VPs, focusing mainly on the production of the morphemes –s (in NP) and the third person plural –nt (in VP). These agreements are particularly interesting in French where number morphology is often silent in the oral

Prophage-Encoded Staphylococcal Enterotoxin A: Regulation of Production in Staphylococcus aureus Strains Representing Different Sea Regions.

The present study investigates the nature of the link between the staphylococcal enterotoxin A (SEA) gene and the lifecycle of Siphoviridae bacteriophages, including the origin of strain variation regarding SEA production after prophage induction. Five strains representing three different genetic lines of the sea region were studied under optimal and prophage-induced growth conditions and the Siph

Diabetes Mellitus Modeling and Short-Term Prediction Based on Blood Glucose Measurements

Insulin-Dependent Diabetes Mellitus (IDDM) is a chronic disease characterized by the inability of the pancreas to produce sufficient amounts of insulin. Daily compensation of the deficiency requires 4-6 insulin injections to be taken daily, the aim of this insulin therapy being to maintain normoglycemia - i.e., a blood glucose level between 4 and 7mmol/l. To determine the quantity and timing of th

Hälsopromotion i skolan. Utvärdering av DISA - ett program för att förebygga depressiva symtom hos ungdomar.

Popular Abstract in Swedish Bakgrund Hälsopromotion i skolan förespråkas för att främja välmående och förebygga depressiva symtom hos ungdomar, men insatsernas effektivitet och kostnadseffektivitet behöver utvärderas löpande. Depressiva symtom klassas av WHO som den största sjukdomsbördan hos unga människor och skapar såväl stort lidande för den enskilda och de anhöriga, som höga samhällskostnaderBackground: DISA (Depressive Symptoms In Swedish Adolescents) is a cognitive behavioral intervention aimed at preventing stress and depressive symptoms in adolescents. It is frequently used in Swedish schools for students aged 13-15 years. DISA is commonly offered to females, but at some schools, the intervention is also offered to males. In this study, the application of the intervention for both

The Contemporary Concept of Significant Versus Insignificant Prostate Cancer

Context: The notion of insignificant prostate cancer (Ins-PCa) has progressively emerged in the past two decades. The clinical relevance of such a definition was based on the fact that low-grade, small-volume, and organ-confined prostate cancer (PCa) may be indolent and unlikely to progress to biologic significance in the absence of treatment. Objective: To review the definition of Ins-PCa, its in

Control and Communication with Signal-to-Noise Ratio Constraints

Popular Abstract in Swedish Reglering och kommunikation med störande brus Hur kan man på bästa möjliga sätt skicka data, till exempel en ljudsignal, när kommunikationen störs av brus och ändå måste ske snabbt? Och hur kan man på bästa sätt styra en process när styrsystemet begränsas av dålig kommunikation? Dessa frågor har undersökts i avhandlingen Control and Communication with Signalto-Noise This thesis is about two problems in the intersection of communication and control theory. Their common feature is that they involve communication over an additive white noise channel with a signal-to-noise ratio (SNR) constraint. The first problem concerns the transmission of a real-valued signal from a partially observed Markov source. The distortion criterion is the mean squared error and the

Self-injection threshold in self-guided laser wakefield accelerators

A laser pulse traveling through a plasma can excite large amplitude plasma waves that can be used to accelerate relativistic electron beams in a very short distance-a technique called laser wakefield acceleration. Many wakefield acceleration experiments rely on the process of wave breaking, or self-injection, to inject electrons into the wave, while other injection techniques rely on operation wit

An elemental diet fed, enteral or parenteral, does not support growth in young pigs with exocrine pancreatic insufficiency.

BACKGROUND: & aims: Young individuals with exocrine pancreatic insufficiency (EPI) show growth reduction that can be reversed by dietary pancreatic enzyme supplementation. Here we investigated whether feeding an elemental diet could replace the growth-promoting effect of enzyme supplementation in EPI pigs. METHODS: Weaned pigs with intact pancreas (control) or pancreatic duct-ligated (EPI pigs

Fetal biometry between 20-42 weeks of gestation for Polish population

Objective: Ultrasound estimating of fetal weight is one of the most frequent examinations during pregnancy. Hitherto, foreign fetometry curves have mostly been used in Poland as there are no national available reference charts that are based on ultrasound fetal biometry. The aim of the present study was to construct new charts based on ultrasound fetometry reference for Polish population. Study de

Breast Tomosynthesis: Aspects on detection and perception of simulated lesions

The aim of this thesis was to investigate aspects on detectability of simulated lesions (microcalcifications and masses) in digital mammography (DM) and breast tomosynthesis (BT). Perception in BT image volumes were also investigated by evaluating certain reading conditions. The first study concerned the effect of system noise on the detection of masses and microcalcification clusters in DM image

Förändringsprocesser i reaktorinneslutningar : betongväggarnas klimatförhållanden och uttorkning

Projektet har haft som övergripande syfte att bedöma och kvantifiera tidigare och framtida förändringsprocesser i betonginneslutningarna i de två typerna av svenska kärnkraftverk. Detta skall kunna utgöra en del av underlaget för bedömning av kvarvarande livslängd hos inneslutningarna. Projektet har lagt huvudvikten vid den pågående uttorkningen av fukten i inneslutningsväggen och hur fuktfördelni

Description and performance of an electron-ion coincidence TOF spectrometer used at the Brazilian synchrotron facility LNLS

This paper reports the characteristics and performance of a Time-of-Flight Mass Spectrometer (TOF-MS) for coincidence measurements between electrons and ions that has been developed jointly in Sweden and Brazil. The spectrometer, used for studies of inner-shell photoexcitation of molecules in the gas-phase, has been optimized by implementing ion and electron lenses to allow the use of relatively s

Ultrasmall Silver Nanopores Fabricated by Femtosecond Laser Pulses

Ultrasmall nanopores in silver thin films with a diameter of about 2 nm have been fabricated using femtosecond laser ablation in liquid. Ultrafast laser pulse ablation generates highly nonequilibrium excitated states, from which silver thin films emerge and progressively grow with the assistance of capping agent molecules. During this growth process, capping agent molecules are enclaved within the
