Thylakoids from the green alga, Dunaliella salina, were fragmented by sonication and the appressed grasna membranes separated from stroma lamellae by partitioning in aqueous two-phase systems. The concentration and antenna size of Photosystem I in the two membrane domains were determined for cultures grown at three different light intensities. Although the antenna size of both PS is decreased with

Tetrakis(dimethyl sulfide)palladium(II) bis(tetrafluoroborate), [Pd(C(2)H(6)S)(4)](BF(4))(2), (I), and tetrakis(1,4-oxathiane-kappaS)palladium(II) bis(tetrafluoroborate), [Pd(C(4)H(8)OS)(4)](BF(4))(2), (II), both crystallize as mononuclear square-planar complexes with tetrafluoroborate as the counter-ions. The Pd atom accepts four S-donor atoms and is positioned at an inversion centre in both comp

This paper describes the implementation of a structure assessmentmethod in an industrial control system. The method uses available signals to evaluate if a given signal can be used for additional feed forward control action to improve the performance of a control loop.

The flux of ultrafiltration membranes may be severely reduced when treating low-molecular-weight hydrophobic solutes even though the cut-off of the membrane is orders of magnitudes greater than the size of the solute molecules. In this investigation, the flux reduction was correlated to the membrane pore size using octanoic acid as a model substance. As a comparison, the pore size was also determi

During the last few years, Swedish municipalities have become increasingly engaged in competition to attract in-migrants. An important element of these efforts has been the use of place- marketing campaigns and promotion. Very little is known, however, about these attempts in terms of the number of municipalities involved, economic efforts, ways of marketing, target groups, etc. Furthermore, and m

The immunodominant T-cell epitope that is involved in collagen-induced arthritis (CIA) is the glycosylated type II collagen (CII) peptide 256-270. In CII transgenic mice, which express the immunodominant CII 256-270 epitope in cartilage, the CII-specific T cells are characterized by a partially tolerant state with low proliferative activity in vitro, but with maintained effector functions, such as

Several studies have shown that alpha-ketoglutaric acid (AKG) increases serum levels of proline and has beneficial effects on skeletal development. We studied the effect of alpha-ketoglutaric (AKG) acid calcium salt (6 g AKG and 1,68 Ca/day) or calcium alone (1.68 Ca/day) on serum C-terminal cross-linked telopeptide of type I collagen (CTX) and osteocalcin (OC), as well as lumbar spine bone minera

In this paper we investigate, determine and classify the critical configurations for solving structure and motion problems for 1D retina vision. We give a complete categorization of all ambiguous configurations for a 1D (calibrated or uncalibrated) perspective camera irrespective of the number of points and views. It is well-known that the calibrated and uncalibrated case are linked through the ci

The thermal elimination reaction that appears in some polycarbonates has been studied by density functional theory (DFT) and ab initio methods of different levels. This work has been focused in the elimination process of ethyl formate, as a good model of this kind of reaction. Different minima and the transition state have been found to characterize the thermal elimination reaction, and the activa

Popular Abstract in Swedish Det förgångna är framtiden är en socialantropologisk studie av ett politiskt skeende som pågått under de senaste 20 åren och som handlar om hur ursprungsfolket kanaka maoli i Hawai´i fått rätt till självbestämmande och andra särskilda rättigheter. Kanaka maoli har använt en diskursiv strategi som handlat om att de en gång i tiden varit ursprungligt suveräna och att dennThe sovereignty- and self-determination movements of indigenous peoples are a salient factor on the political agenda in many western world countries. Indigenous peoples in Hawai´i and elsewhere have become increasingly politicised in hope of changing their relationship with the states within which they are located. The discourse of indigenous peoples turn around the concept ”First Nations” whose c

Popular Abstract in Swedish Denna undersökning inventerar beståndet av beteckningar för EGENDOM I ALLMÄNHET och för MOBIL och IMMOBIL EGENDOM i de regionala medeltida nordiska lagarna (dvs. de danska och svenska landskapslagarna, de norska lagtingslagarna samt den isländska Grágás). Materialet analyseras språkgeografiskt med avsikten att skapa en relativ termkronologi. En grovanalys visar attféThis study investigates the stock of words for PROPERTY IN GENERAL with the subcategories MOVABLE and IMMOVABLE PROPERTY in the regional medieval Scandinavian laws and makes a linguistic-geographical analysis of these words with the aim of establishing a relative term chronology. A crude analysis shows that fé/fæ for PROPERTY IN GENERAL and land for IMMOVABLE PROPERTY were the oldest
