Objectives. Accidents in health care, resulting in injury or death to the patient, are a matter of considerable concern. The aim of this study is to examine whether system weaknesses can contribute to these accidents, and if so, how. Design. Eight consecutive accidents reported to the Health Authority in Sweden were analysed using MTO (Man-Technique-Organization) analysis. Setting. Emergency care
Background Phobic postural vertigo is characterized by dizziness in standing and walking despite normal clinical balance tests. Patients sometimes exhibit anxiety reactions and avoidance behavior to specific stimuli. Different treatments are possible for PPV, including vestibular rehabilitation exercises, pharmacological treatment, and cognitive behavioral therapy. We recently reported significant
Many birds and mammals store energy as hoarded food supplies. A supply of stored food is beneficial during periods when food is scarce, but building up and managing such a supply also entails costs. The optimal number of caches will be reached when the net benefit is at its maximum. If dominants can steal more stored food from subordinates than the other way around, the optimum will differ between
Occupational therapy researchers have tried to clarify the links between occupation and statelike characteristics, such as people's experienced health, disability, and quality of life. However, to fully examine the spectrum of potential influences on occupation, trait-like features should also be investigated. This study focused on personality and self-related factors, in terms of temperament, cha
Nested convolutional codes are a set of convolutional codes that is derived from a given generator matrix. The structural properties of nested convolutional codes and nested generator matrices are studied. A method to construct the set of all minimal (rational) generator matrices of a given convolutional code is presented. As an example, two different sets of nested convolutional codes are derived
Return sludge from two Swedish and two Danish wastewater treatment plants were hydrolysed in laboratory reactors. Treatment plants with/without pre-sedimentation and with/without nitrification were represented. Soluble organic matter was produced from all types of sludge, but the yield was to a large extent dependent on what type of sludge was hydrolysed. Activated sludge from wastewater treatment
Prevention of first time disease or recurrence of coronary heart disease (CHD) is a major task for the health service. Guidelines regarding CHD prevention have been issued but studies have shown that treatment goals are inadequately met in clinical practice and there is urgent need for improved methods of implementation of guidelines. There is also a need for better risk stratification tools in or
Abstract in Undetermined Undersökningen utfördes i form av schaktningsövervakning av Riksantikvarieämbetet UV Syd. Schaktbredden uppgick som mest till 1m och djupet uppgick till 1,6 m. Vid undersökningen framkom 380 stratigrafiska enheter, mestadels dokumenterade i sektion, dessutom tillvaratogs 45 fyndposter framförallt bestående av djurben och keramik. Lämningarna kunde delas i tre olika bebyg
We compared reproductive allocation and variation in condition and survivorship of two heritable female throat color morphs (orange and yellow) in a free-living population of side-blotched lizards (Uta stansburiana). Using path analysis and structural equation modeling, we investigated how variation in the social environment affected clutch size and egg mass and two condition traits (postlaying ma
The coexistence of two lamellar liquid-crystalline phases in equilibrium for binary surfactant-water systems is a rare and still puzzling phenomenon. In the few binary systems where it has been demonstrated experimentally, the surfactant is invariably ionic and the miscibility gap is thought to stem from a subtle balance between attractive and repulsive interbilayer forces. In this paper, we repor
The application of the protein and polysaccharide fractions of barley spent grain as a basis of growth media for probiotic bacteria was studied. High values of biomass yield, cell viability, and organic acid production were observed in the variants of media containing the barley spent grain supplemented with lactose, ascorbic acid, yeast extract, and mineral salts. Cells of lactic acid bacteria an
We have used a human tumor nude mouse model involving heterotransplantation and serial passage of an estrogen receptor (ER) positive, progesterone receptor (PgR) negative human endometrial adenocarcinoma. The effects of estradiol treatment on tumor growth, ER activation and PgR induction were investigated two and four years after heterotransplantation. In Experiment I, two years after initial hete
