Phytochrome from oats (Avena sativa L. cv. Sol II), partially purified on brushite, was immobilized on Sepharose beads to which antiphytochrome immunoglobulin had been covalently linked. The immobilized phytochrome was first brought to the Pr form with unpolarized far-red light. The change in linear dichroism at 660 nm induced by plane polarized red light, and its reversal by plane polarized far-r

We study the probability distribution of the height of global maximum for a Gaussian random field evolving in time. Particularly, we discuss the role of the wave kinematics. It is observed that taking into account time dynamics of spatial characteristics results in distributions different from those obtained for the static case. We show how different characteristics of the sea surface like signifi

Abstract in UndeterminedThe questions dealt with in the course of this workshop are greatly complex. In order to outline the state of the art in Southern Scandinavia the character of the archaeological and palaeobotanical source material and different theories on early agriculture are summarized. Theoretical and methodological problems implied in ecological and archaeological interpretations of th

Purpose: To evaluate the functional disorders of the oral and pharyngeal phases of deglutition after repair of esophageal atresia in children. Material and Methods: 19 children (10 girls, 9 boys, mean age 22 months) underwent videofluoroscopy of deglutition after repair of esophageal atresia. The videofluoroscopic studies were assessed according to functional and morphological changes in the oral,

A general mass calibration procedure of a PIXE set-up is described. As an example, the results of the calibration of the PIXE set-up in Lund are given. For the calibration commercially available standards were used. The parameters of a physical model were adjusted to fit a calibration curve. To decrease errors due to inhomogeneities of the standard foils, the average from four different pieces of

Ball rolling by dung beetles is considered to be a derived behaviour that evolved under pressure for space, and from competitors at the dung pat. Straight-line orientation away from the pat using a celestial cue should be the most successful rolling strategy to move dung to an unknown burial site. We tested this hypothesis in the field and the laboratory by presenting five species of ball-rolling

Analysis of Emanuel Swedenborg and his conceptual understanding of writing

PCB concentration in river water at the outlet of a lake was monitored far two years following the completed remediation of the PCB contaminated sediment of the lake. The remediation resulted in lowered PCB concentration in the sediment, from 5 mu g g(-1) (d.w.) to 0.060 mu g g(-1) (d.w.). PCB concentration in the water decreased over the two years, but varied seasonally. Highest PCB concentration

The complex formation between HOO and SO2 in argon matrices has been studied with FTIR spectroscopy. The complex shifts of the intramolecular fundamentals of the complex components suggest the formation of a complex, where HOO acts as a lone pair donor to the sulfur atom of SO2 while its hydrogen atom is sufficiently close to one of the oxygen atoms of SO2 to give a significant blue shift of the H

This study seeks to find answers to the question of how much competition is introduced by different types of regulation aimed at promoting electricity generated with renewable energies. For this purpose the partial equilibrium model is applied. Further analysis of the costs of governance for two realised regulations, the German EEG and the Texas RPS, is based on Transaction Cost Economics.

OBJECTIVE: To investigate markers of endothelial activation in muscle biopsies from rheumatoid arthritis (RA) patients with and without extra-articular manifestations (ExRA). PATIENTS AND METHODS: Nine consecutive ExRA patients were compared with nine RA controls without ExRA, matched for age, sex and duration of RA. Muscle biopsies were obtained from the lateral vastus or anterior tibial muscle.

Popular Abstract in Swedish Korsningsintensiteten for en stationär stokastisk process är ett värdefullt verktyg när man studerar fördelningen för våghöjder och för maxima av havsnivån. Denna avhandling betraktar två approximationstekniker för fall då korsningsintensiteten inte kan ges exakt.Båda tekniker använder en asymptotisk expansion, och första och andra ordningens termer i denna approximatioThe crossing rate of a stationary random process is a valuble tool when studying crest hight distributions and maxima of sea level elevation. This thesis considers two approximation techinques for cases when the crossing rate cannot be exactly computed. Both techniques use an asymptotic expansion, and the first and second order terms in these expansions are given explicitly. Paper A describes how
