BACKGROUND: Patients with prosthetic heart valves have an increased risk of thromboembolic events, and transcranial Doppler sonography reveals microembolic signals. Whereas microembolic signals were initially assumed to be of particulate matter, recent studies suggest that they are partially gaseous in origin. If this is true, alteration of environmental pressure should change microembolic signal

Som journalist och fotograf var Lennart Williams framför allt knuten till Ljungby-Tidningen Smålänningen, men han publicerade sig flitigt som naturskribent även i många andra publikationer. Den här uppsatsen tar fasta på ett nostalgiskt tema i de naturkrönikor han skrev i Göteborgs-Posten under åren 1957-87.

First results on charm quarkonia production in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) are presented. The yield of J/psi's measured in the PHENIX experiment via electron-positron decay pairs at midrapidity for Au-Au reactions at roots(NN) = 200 GeV is analyzed as a function of collision centrality. For this analysis we have studied 49.3x10(6) minimum bias Au-Au reactions

Cross sections for elastic production of J/psi mesons in photoproduction and electroproduction are measured in electron proton collisions at HERA using an integrated luminosity of 55 pb(-1). Results are presented for photon virtualities Q(2) up to 80 GeV2. The dependence on the photon-proton centre of mass energy W-gamma p is analysed in the range 40 <= W-gamma p <= 305 GeV in photoproduction and

Den okritiske läsaren kan få uppfattningen att det råder konsensus om definitionen av begreppet livsstil med samma exakthet som en medicinsk diagnos. Så är ingalunda fallet. Det är oftare så att det är det slarviga bruket av ordet livsstil som gjort det så välbekant för en större allmänhet. Begreppet livsstil kommer här att analyseras i efter två huvudlinjer. Den ena har sin grund i empirisk forsk

This paper investigates a variety of forms of management control in a large management consultancy company. The very high level of compliance with corporate objectives among employees is highlighted and singled out as a phenomenon worth exploring. The company exhibits a rich variety of various formal control devices focusing on financial issues as well as human resources. The paper shows that thes

We study the history of storminess in Northern Europe, as derived from local pressure observations in Lund since 1780 and Stockholm since 1820 ( Sweden). At both stations barometer readings were made three times per day, morning, midday and evening, and after about 1850 at fixed observation hours. We use four common storminess indices: annual number of deep lows ( p < 980 hPa), the annual 95th and

In this paper, the authors report the use of liquid-liquid partition chromatography (LLPC) in an aqueous polyethylene glycol (PEG)/dextran two-phase system to compare the surface properties (partition properties) of human antibodies and fragments thereof. The surface properties of all the monoclonal antibodies of different classes and subclasses investigated were within the same broad range as tha

Popular Abstract in Swedish I ett ökande antal regioner i världen finns det arbetande barn som organiserar sig utifrån sin identitet som arbetande barn. Jag har studerat tre olika unioner i delstaten Karnataka i Indien, där jag har fokuserat på hur dom själva upplever mobiliseringen och vilka möjligheter de har att förändra sin situation inom existerande normer, traditioner och samhällsstrukturer.A number of working children in several regions over the world are mobilising to fight for better working conditions and to gain their rights according to how they interpret the Child Rights Convention (UNCRC) from 1989. Despite the increasing focus on child participation, their approaches and their demands are in many aspects controversial and they are often met with suspicion among diverse actor

Objectives: To investigate side by side the effects on serum lipoproteins and postprandial glucose and insulin concentrations of beverages enriched with 5 or 10 g of beta-glucans from oats or barley. Design and setting: An 8-week single blind, controlled study with five parallel groups carried out at two centres under identical conditions. Interventions: During a 3-week run-in period all subject

It has been suggested that a parent–teacher–student conference should centre on the capacities and good qualities of the student. This article focuses on teacher discourse in situations where the students’ answers (in mathematics tests, written assignments etc.) are either entirely or almost entirely correct. The study shows that, in eight cases out of ten, the comments made reflect a “deficiency

The effect of pulsed electric field (PEF) pretreatment on solid-liquid expression from potato tissue was studied on individual parenchyma tissue samples for different PEF intensities, varying relative deformations and deformation rates. The yield increased with relative deformation. The yield at any given relative deformation increased with increased PEF intensity and decreased deformation rates.

Popular Abstract in Swedish Flertal studier talar för att såväl vaskulär demens som demens av Alzheimers typ är relaterade till blodtrycksnivå tidigare under livet. En studie har visat att redan blodtrycket vid 50- årsåldern är relaterat till kognitiva (intellektuella) funktioner vid 70-års ålder. En annan studie har visat att hypertoni i 70-årsåldern föregår utveckling av demens i ålder 80-85 år."Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. Examination included a medical and a psychological investigation, ultrasonographic measurement of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flo

Diffractive interactions represent a lively domain of investigations, as confirmed by the progresses reported during the conference. We summarize the diffractive interactions session and put the new experimental data (Section 1), developments in modeling diffraction (Section 2) and the theoretical relations with Quantum Chromodynamics (Section 3) in perspective.
