Popular Abstract in Swedish Denna studie visar betydelsen av ökad idrottsundervisning, fysisk aktivitet och extra motorisk träning i skolan. Undersökningen är en delstudie i Bunkefloprojektet - en hälsofrämjande livsstil. Interventionen består i att två årskullar elever har en obligatorisk rörelselektion varje skoldag. Motorikobservationer med MUGI observationsschema som underlag genomförs varje åThe aim of this thesis is to study effects of an extension of physical education/activity and motor training on motor skills, attention and cognition during a period of three years. Another aim is to develop a test, MUGI observationsschema, which could be useful in charting motor skills of school pupils. The study has two intervention groups (n=152) that have physical activity and motor training o

The introduction of PACS in a radiology department means that most functions that are available in the film-based system must be included. One important function is the radiology conference. The handling and application programs of digital workstations are normally not developed for demonstrations of many images in a limited time. This paper describes a workstation with specially designed software

Injectable bone substitutes (IBS) based on calcium phosphate (CaP) and/or calcium sulphate (CaS) are used as fillers in bone defects to stimulate bone integration and allow mechanical loading. Two types of IBS, IBS-1 is CaP+20%CaS and IBS-2 is CaS+40% hydroxyapatite, were investigated. The materials were injected into holes in the femur and tibia in rabbits. After 10 weeks the femora were subjecte

Using high resolution core level spectroscopy, a surface core level shift towards lower binding energy of -0.13 eV is determined for the 2p level of the outwardly relaxed Al surface atoms on NiAl(110). Density functional theory based calculations with inclusion of final state effects yield a value of -0.14 eV for this shift in excellent agreement with experiment. We show that the initial state app

PURPOSE: In an experimental study in rats a correlation between nutritional status and hepatic attenuation in CT and signal intensities in MR imaging was shown. Is physiological nutritional status of importance in clinical CT and MR imaging? MATERIAL AND METHODS: In a cross-over study including 12 healthy volunteers (6 women and 6 men, mean age 34 years), CT and MR imaging of the liver were perfor

The optical response of isolated holes in 20 nm thin gold is probed as a function of alkanethiol CH3(CH2)(x)SH (x is an element of 1-15) and protein adsorption using dark-field spectroscopy. We establish that the plasmon excitations of single and short-range ordered 60 nm holes exhibit similar E-field decay lengths delta approximate to 10-20 nm and that a single hole can be used to resolve the suc

Thirteen piston and gravity cores from the Faroe-Shetland area were investigated for their planktic and benthic foraminiferal and oxygen isotopic distributions. Eight time-slices between 18 ka BP and the present were reconstructed to study variations in surface and deep water exchange between the SE Norwegian Sea and the northeast Atlantic Ocean. Today, a relatively strong northward flow of warm N

Dermatan sulfate (DS) chains are variants of chondroitin sulfate (CS) that are expressed in mammalian extracellular matrices and are particularly prevalent in skin. DS has been implicated in varied biological processes including wound repair, infection, cardiovascular disease, tumorigenesis, and fibrosis. The biological activities of DS have been attributed to its high content of IdoA(alpha 1-3)Ga

Saccharomyces cerevisiae mutants, in which open reading frames (ORFs) displaying similarity to the aldo-keto reductase GRE3 gene have been deleted, were investigated regarding their ability to utilize xylose and arabinose. Reduced xylitol formation from D-xylose in gre3 mutants of S. cerevisiae suggests that Gre3p is the major D-xylose-reducing enzyme in S. cerevisiae. Cell extracts from the gre3

Abstract in Undetermined NMR line shape analysis and relaxation dispersion measurements for N,N-dimethyltrichloroacetamide (DMTCA) weakly aligned using poly-γ-benzyl-l-glutamate, which forms a lyotropic nematic phase when dissolved in chloroform, were used to characterize chemical exchange kinetics for the rotation around the C−N amide bond. At low temperatures (<312 K), slow-exchange 1H-coupled 1

We examine the near-field optical properties of multilayered metal core-shell sphere nanostructures by extending the Mie theory, and demonstrate that the local-field enhancement can be increased by adding new metal shells. A local intensity enhancement of more than 10(5) times can be obtained in the cavity between the Ag core and the innermost Ag shell for proper configurations of multilayered Ag

I dagens samhälle krävs i många fall genomförande av risk- och/eller konsekvensanalyser. Krav ställs dels från myndigheter och dels inom enskilda företag och organisationer. Här kommer endast konsekvensanalyser att behandlas. Anledningen till att genomföra en konsekvensanalys kan skifta. Som nämnts kan krav på en konsekvensalanys komma utifrån från myndigheter och dels kan en analys utföras för at
