We report partial cation and anion-yield measurements around the N K edge in isolated ammonia molecules. Due to the dominance of spectator electronic decay following Rydberg excitations, fragmentation was found to be more extensive following excitation to intermediate states of Rydberg character compared to excitation of states with molecular-orbital character. Unusual stability of the NH32+ fragm

Aims Between 1998 and 2005, a number of definitions of the metabolic syndrome (MetS) have been proposed. The aim of this population-based cohort study was to compare prevalence rates and the prediction of cardiovascular disease (CVD) using different definitions of MetS. Methods A total of 5047 non-diabetic subjects (66% women), from the city of Malmo, Sweden, were followed. The incidence of fatal

Fluctuations in the fluorescence polarization degree and direction are reported for the first time for single conjugated polymer molecules embedded in a polystyrene matrix at room temperature. The polymer molecule, a polythiophene derivative, clearly emits as a multi-chromophore ensemble showing that the energy does not funnel to any specific low-energy trap. The fluorescence instead originates fr

Psychology's subject-matter is, admittedly, complicated and difficult to handle. Over the years psychologists have tried various approaches to make their endeavours more plain and manageable. One attempt at simplification is to deny the subjective side of psychic reality and exclusively focus behavioral facts. Another way is reduction of psychic events to somatic counterparts. And a third alternat

We report on endovascular repair of a ruptured abdominal aortic aneurysm. A bifurcated stent graft was inserted under local anesthesia. Aortic clamping is rapidly provided by percutaneous placement of an aortic occlusion balloon catheter. Carbon dioxide can usually replace conventional contrast in patients with renal insufficiency. This minimally invasive procedure may reduce perioperative morbidi

The latest outburst of AG Peg has lasted for 150 years, which makes itthe slowest nova eruption ever recorded. During the time of IUEobservations (1978-1995) line profiles and intensity ratios of the N Vand C IV doublet components changed remarkably, and we discuss plausiblereasons. One of them is radiative pumping of Fe II which is investigatedby studying the fluorescence lines from pumped levels

Popular Abstract in Swedish Det övergripande syftet med föreliggande studie är att utveckla en bättre förståelse om vad det innebär att vara montessorilärare. Utgångspunkten är lärarnas egna liv- och verksamhetsberättelser. Insamling av data har skett genom loggböcker, intervjuer, skriftliga reflektioner och diskussioner. Analys av lärarnas livsberättelser i samband med övriga data har granskats fThe overall aim of this study has been to come to a better understanding of what it means to be a Montessori teacher, by getting a group of Montessori teachers to reflect on their lives and work. Data exploration has comprised journals, interviews, written reflections and collaborative contextual analysis. Analysis of the teachers' occupational life histories and the findings as a whole have been

Popular Abstract in Swedish Homocystein är en aminosyra som bildas genom nedbrytning av aminosyran metionin, som tillförs kroppen via födan. Förhöjda blodnivåer av homocystein kan orsakas av medfödda enzymrubbningar, brist på vitaminerna folsyra och B12, och vissa sjukdomar, t ex njursvikt. Medfödd enzymbrist kan ge mycket höga blodnivåer av homocystein, vilket bland annat leder till kärlskada ochAn elevated plasma level of homocysteine has been suggested as a risk factor for cardiovascular disease. The objectives of this thesis were to study the influence of renal function on homocysteine levels in patients with coronary artery disease and to explore the association of elevated plasma levels of homocysteine to oxidative stress, inflammation, and endothelial dysfunction. The effects of pla

When modelling material mechanical behaviour, an analytical description is required of the relationship between stresses and strains. A computer oriented mechanical behaviour model for steel is described. The model is based on the fact that the deformation process at transient high temperature conditions can be desribed by three strain components which are separately found in different steady stat

Popular Abstract in Swedish Neurodegenerativa sjukdomar karaktäriseras av långsam celldöd i hjärnan med en gradvis försämring av olika funktioner hos patienten. Ytterligare en gemensam nämnare är att de idag inte går att bota. En av dessa är Parkinsons sjukdom, som drabbar ungefär 0.1% av befolkningen, och inträder oftast i femtio- till sextioårsåldern med minskad rörlighet och muskelstelhet som mNeurodegenerative disorders are characterized by a progressive cell-death in the brain, and loss of different functions in the patient. Today, there are no cures for any of the various diseases. Parkinson's disease is a neurodegenerative disorder with a prevalence of 0.1% and the first symptoms usually start to appear between 50-60 years of age with rigidity, tremor, bradykinesia and postural abno

Objective: To evaluate risk factors - notably drugs - for developing acute pancreatitis. Methods: A population-based, case-control study, encompassing 1.4 million inhabitants aged 20-85 years from four regions in Sweden between 1 January 1995 and 31 May 1998. A total of 462 cases were hospitalised in surgical departments with their first episode of acute pancreatitis without previously known bilia

Calcitonin gene-related peptide (CGRP) and related peptides may be involved in migraine pathogenesis. To understand their vasomotor role in the cerebral circulation, we performed two studies, a pressurized arteriography study of the middle cerebral artery (MCA) and a genuine closed cranial window (gCCW) in vivo study. Using the pressurized arteriography model rat MCAs were mounted on micropipettes

BACKGROUND: Chondromalacia patellae is a potentially disabling disorder characterised by features of patellar cartilage degradation. OBJECTIVE: To evaluate markers of cartilage and bone turnover in patients with chondromalacia patellae. METHODS: 18 patients with chondromalacia patellae were studied. Serum cartilage oligomeric matrix protein (s-COMP) and bone sialoprotein (s-BSP) levels were measur

A total of 301 adult questing Ixodes ricinus ticks were collected at 15 different locations along the south and east coasts of Sweden to determine the Borrelia genospecies diversity. Thirty-two ticks (11%) were found to be positive by nested PCR with Borrelia burgdorferi sensu lato-specific primers. Species determination was based on partial sequencing of the 16S rRNA gene and the flagellin gene.
