Popular Abstract in Swedish Gastroesofageal refluxsjukdom innebär att maginnehåll backar (reflux) upp från magsäcken till matstrupen på ett onormalt sätt. Hos den friska individen finns flera mekanismer som skyddar matstrupen från reflux, vilket tydligt åskådliggörs av att man efter en måltid kan ställa sig upp och ner utan att föda backar upp i matstrupen. Vid refluxsjukdom föreligger defekter inEsophageal pH monitoring is important in the clinical management of patients with symptoms suggestive of gastroesophageal reflux disease (GERD), and in research aiming to clarify the mechanisms involved in the development of GERD complications. Catheter-based techniques for pH recording are uncomfortable, not well tolerated by all patients and cannot reliably measure acid exposure in the most dist

This thesis investigates a set of degree modifiers of adjectives common in spoken British English. The main focus of the study is on generalizable semantic and intonational features, but attention is also given to the use of the modifiers in authentic speech in terms of frequency, collocability and intonation. The study explores the semantic constraints that govern the relationship between degree

BACKGROUND: Thrombosis is one of the most important causes of morbidity in the medical field. Several independent in vitro studies have shown that the fibrinolytic process may be enhanced by ultrasound, but the effect of ultrasound on thrombus formation in vivo is unexplored. The present study was designed to investigate this matter. METHODS: In a blind randomized study, standardized arteriotomies

Artikeln belyser exilens tematik i texter av Paul Celan, Emmanuel Levinas och Zvi Kolitz.

Muslimer framställs idag som sexualfientliga puritaner, medan de inom orientalismen sågs som lustfyllda med en bestialisk, okontrollerad sexualitet i sina harem. Muslimer har konstruerats som ”den andra” i relation till väst, men vad vet vi egentligen om muslimsk sexualitet? I artikeln hävdas att muslimer traditionellt har haft en öppnare inställning till sexualitet än den strikta sexualmoral som

In this work the problem of designing feedback controllers for the rejection of narrow-band disturbances is considered. The design technique proposed herein is based upon a well-suited overparameterization of a standard model-based minimum-variance controller; the extra-degrees-of-freedom so introduced are used to improve the performence of the basic controller. In particular, the problem of impro

Background: Immediate recurrence of atrial fibrillation (IRAF) occurs frequently after electrical cardioversion, its electrophysiological determinants and prognostic significance hove, however, not been studied in detail. This Study aimed to explore (1) the association of IRAF with clinical characteristics, pulmonary vein (PV) arrhythmogenicity as well as atrial electrophysiologic properties and (

Persons with autism develop along trajectories that differ from the typical. Therefore, development itself gives important clues for understanding the behavioral profile characteristic of autism. Developing autism means being different, not necessarily being deficient. The infant and her environment coevolve, and therefore experience of a dynamic world is important in shaping both brain and behav

Popular Abstract in Swedish Avhandlingen består av tre teoretiska uppsatser inom förhandlingsteori och Social choice. Den första uppsatsen försöker bibehålla den entydiga jämvikten i Rubinsteins förhandlingsmodell när man utökar förhandlingsspelet till att omfatta fler än två spelare. Vi åstadkommer en entydig delspelsperfekt jämvikt i en förhandlingsmodell med tre spelare genom att anta att spelaThis thesis consists of three theoretical essays on Bargaining and Social Choice. The first essay addresses the problem of retaining the uniqueness of equilibrium when extending the Rubinstein model to accommodate more than two players. We achieve a unique subgame perfect equilibrium in a bargaining model with three players by assuming that the players make demands in a clockwise order and practic

This study investigates factors of importance for tadpoles survival and metamorph production in the common frog Rana temporaria. It also assess the importance of this for the population dynamics of the species. Eighteen ponds were studied for up to 8 years. Data collected each year included: number of spawn clumps deposited, tadpole number and metamorph number. The permanency of the ponds was also

An experimental study of the normalized three-jet rate of b quark events with respect to light quarks events (light = l equivalent to u, d, s) has been performed using the CAMBRIDGE and DURHAM jet algorithms. The data used were collected by the DELPHI experiment at LEP on the Z peak from 1994 to 2000. The results are found to agree with theoretical predictions treating mass corrections at next-to-

Reactive oxygen species (ROS) produced by the phagocyte NADPH oxidase complex are important in the killing of invading pathogens. Lately, a role of ROS has been suggested in regulation of the immune system. This was further highlighted when the Ncf1 gene, encoding a subunit of the NADPH oxidase complex, was found to regulate arthritis severity in rats. Interestingly, the fact that increased arthri
