A prospective study was carried out in 499 patients admitted to a coronary care unit (CCU) in order to evaluate the incidence of clinically significant electrolyte disturbances. Low serum potassium values (less than 3.6 mmol l) occurred in 7% of the CCU patients and low serum magnesium values (less than 0.70 mmol l-1) in 6%. Few patients had low values of both these ions (1.9%). In 49 patients the

In all societies, personal names are important as a means for recognizing and distinguishing people. The paper, following Claude Lévi-Strauss’ theories on how people systematize the surrounding world through named categories, focuses on how we use names to gain knowledge about who a person “is”. We base our conclusions on culturally shared knowledge about how specific names are related to gender,

With the increasing, use of short-range wireless devices for high-data-rate communication in the shared frequency bands, the level of interference can be expected to increase. The ability to,estimate, the performance degradation of these devices due to increasing interference is, therefore, important. In this paper, the throughput of devices that perform frequency hops after each transmitted packe

Bilateral foreign aid negotiations between industrialized and less developed countries; based on conference paper. Characteristic features of foreign aid negotiations, as compared to other types of negotiations between states; influence of factors which are external in relation to the negotiations themselves.

A soft x- ray laser from Ni- like Mo, pumped in grazing incidence ( GRIP), is analyzed with regard to high repetition rate operation. Reliable lasing is obtained, but with significant energy fluctuations attributed mainly to beam pointing jitter from the pump laser. Two modes of operation are compared: continuously moving target and stationary target. With a moving target the soft X- ray output is

To investigate whether biotransport constitutes an entry route into pristine ecosystems for nonpersistent, nonvolatile xenobiotic compounds, extractable organically bound halogen in sockeye salmon (Oncorhynchus nerka) from Alaska was determined before and after spawning migration. The major organohalogen compounds in the salmon were halogenated fatty acids, predominantly chlorinated species that a

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
