This perspective discusses multi-functional biomass production systems, which are located, designed, integrated and managed so as to provide specific environmental services, in addition to biomass supply. Besides discussing the general concept and outlining a range of different possible applications, we present in somewhat more detail specific applications of such systems for the cases of Sweden a

The enzymatic activity of tyrosinase was studied both in aqueous and organic media. In the latter case tyrosinase was entrapped in a system of reverse micelles of Aerosol OT in octane. At hydration degree 25, when the inner cavity of the reverse micelles was comparable with the size of a tetrameric tyrosinase form known for aqueous solutions, an optimum level of catalytic activity was observed. An

Clinical studies with intrastriatal transplants of embryonic mesencephalic tissue in patients with Parkinson's disease (PD) provide proof-of-principle for the cell replacement strategy in the diseased human brain. The grafted dopaminergic neurons can reinnervate the denervated striatum, restore regulated dopamine release and movement-related frontal cortical activation, and give rise to significan

When a shotgun phage-display library of Staphylococcus aureus Newman was affinity selected (panned) against recombinant von Willebrand factor (vWf), a novel von Willebrand factor binding protein (vWbp) was found. Experimental data indicate that the interaction between vWbp and vWf is very specific and mediated by a region of 26 aa residues in the C-terminal part of vWbp. vWbp has an N-terminal sec

The purpose of this study was to investigate the relationship between student influence, students' strategic approaches to studying and academic achievement, and to examine differences between students in a Master's programme in Engineering with conventional teaching and one based on problem-based learning in a sample of 268 students. A version of the Approaches and Study Skills Inventory for Stud

Objective-The aim of the present study was to describe how the diagnosis of heart failure (HF) was assessed, aetiology and management in elderly patients with non-insulin-dependent diabetes mellitus (NIDDM) in primary health care, with special reference to use of echocardiography. Design-Descriptive retrospective investigation. Setting-Ronneby and Karlskrona communities, both situated on the Swedi

Glass is often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. Experimental methods based on etching to determine the depth distribution of recoil-implanted 210Po in glass from radon decay in air is presented. By carefully controlling chemical concentrations and exposure time during which the glass is etched, stepwis

Basic neurotransplantation research evoked clinical trials of restorative brain surgery. Parkinson's disease was the first and primary test bed for this putative new therapeutic method. Various centers performed the grafting surgery and the behavioral evaluations in different ways, and observed a varying degree of symptomatic relief. This led to a plea for double blind placebo-controlled clinical

The relation between the œuvres of Jurgen Habermas and Michel Foucault constitutes an important reference point to several aspects of contemporary social research and philosophical discussion. In this paper I give an account of Habermas's critique of Foucault, a critique which operates on three levels-methodology, empirical descriptions, and political implications. I also make some commentaries on

Transplantation of allogeneic embryonic neural tissue is a potential treatment for patients with Parkinson's and Huntington's diseases. The supply of human donor tissue is limited, and alternatives such as the use of animal (e.g., porcine) donor tissue are currently being evaluated. Before porcine grafts can be used clinically, strategies to prevent neural xenograft rejection must be developed. Kn

Reaction of [Re-2(CO)(9)(NCMe)] with tri(2-thienyl)phosphine (PTh3) in refluxing cyclohexane affords three substituted dirhenium complexes: [Re-2(CO)(9)(PTh3)] (1), [Re-2(CO)(8)(NCMe)(PTh3)] (2), and [Re-2(CO)(8)(PTh3)(2)] (3). Complex 2 was also obtained from the room-temperature reaction of [Re-2(CO)(8)(NCMe)(2)] with PTh3 and is an unusual example in which the acetonitrile and phosphine ligands

We investigate, for quotients of the non-commutative polynomial ring, a property that implies finiteness of Gröbner bases computation, and examine its connection with Noetherianity. We propose a Gröbner bases theory for our factor algebras, of particular interest for one-sided ideals, and show a few applications, e.g. how to compute (one-sided) syzygy modules.

The phylogeny of Alisma (Alismataceae), a genus of approximately nine species of aquatic plants mainly distributed in the Northern Hemisphere, was reconstructed with parsimony analysis on RAPD data and sequences of the nuclear ITS and chloroplast trnL regions, and with MDS on RAPD data. Separate analyses were performed on each data set. Butomus umbellatus was used as outgroup in the analysis of se

Fondaparinux is a new anticoagulant that interacts with antithrombin III and activated coagulation factor X resulting in an inhibition of the coagulation system. It has been successful in doses of 2.5 mg for thromboprophylaxis as well as in higher therapeutic doses of 5-7.5 mg. No optimal method for monitoring the effects of fondaparinux has been proposed. The aim of the present study was to inves
