The effect of core polarization on binding energies, term splitting, fine structure, and transition probabilities is investigated for the low lying states 4s2S, 3d2D, 4p2P(o) in Ca II and 4s2(1)S, 4s4p1,3P(o) in Ca I. Results from inclusions of core polarization in the form of model potentials are compared with explicit MCHF calculations, and the accuracy of the different approaches is discussed.
Abstract in French La géométrie du tissue urbain a une grande influence sur le microclimat et influence donc le confort thermique extérieur des habitants et, le microclimat urbain influence à son tour indirectement le climat intérieur. Une mauvaise adaption climatique des environnements urbains a souvent pour conséquence l'utilisation d'une climatisation active et ainsi une augmentation de la cons
A jawed polychaete fauna from the upper 30 in of the Upper Ordovician Sylvan Shale (Richmondian, Ash-ill) of Oklahoma is described, based on recovered scolecodonts (polychaete jaws). The fauna includes members of six families: Paulinitidae, Ramphoprionidae, Polychaetaspidae, Atraktoprionidae, Hadoprionidae, and Kalloprionidae. Ten species are identified and one new paulinitid species, Ketmerites (
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
