The paper discusses the results of a time dynamic analysis of the possible effects of government and utility sponsored energy efficiency programmes on lighting energy use in Sweden. Scenarios are developed of electricity demand and efficiency improvement, based on various types of energy performance standards and utility demand-side management (DSM) investments. The scenarios account for the dynam

Theoretical oscillator strengths for transitions between the even 4s(2) 4p(2) and the three odd {4s4p(3), 4s(2)4p4d, 4s(2)4p5s} configurations of As+ are reported. Both ab initio, multiconfiguration Hartree-Fock and semiempirical configuration interaction techniques are used. The uncertainty of the results are estimated, by considering the reproduced energy structure, the agreement of results from

We introduce two novel joint radio-frequency (RF)-baseband designs for receivers in a MIMO system with Nt transmit antennas, Nr receive antennas, but only L < Nr RF chains at the receiver. The joint design introduces an RF pre-processing matrix that processes the signals from the different antennas, and is followed by selection (if necessary), down-conversion, and further processing in the baseban

1. The structure of chondroitin/dermatan and heparan-sulphate chains from various proteoglycan populations derived from cultured human skin fibroblasts have been examined. Confluent cell cultures were biosynthetically labelled with [3H]-glucosamine and 35SO4(2-), and proteoglycans were purified according to buoyant density, size and charge density [Schmidtchen, A., Carlstedt, I., Malmstrom, A. &am

Deficiencies of the early components of the classical complement pathway impair the actions of innate and humoral immunity and may lead to increased susceptibility to infections. We have studied the genetic basis of total C4B deficiency in a Finnish patient with recurrent meningitis, chronic fistulas and abscesses. The maternal chromosome carried a four-gene deletion including the C4B gene, and a

A scintillating fibre tracker is proposed to measure elastic proton scattering at very small angles in the ATLAS experiment at CERN. The tracker will be located in so-called Roman Pot units at a distance of 240 m on each side of the ATLAS interaction point. An initial validation of the design choices was achieved in a beam test at DESY in a relatively low energy electron beam and using slow off-th

Radiative lifetime measurements were performed with time-resolved laser-induced fluorescence techniques for 47 levels of the astrophysically important ion Sm1+ over the energy range 21000-36 000 cm(-1). The new results have been compared with previous measurements but also with theoretical calculations taking configuration interactions and core-polarization effects into account, and a satisfying a

Background and Objectives Reagent red blood cells (RBCs) for antibody detection should express certain important antigens as a double dose, that is, the donors must be homozygous for the corresponding alleles. Traditionally, dose is determined by serological typing and known allele frequencies. However, RHD zygosity cannot be predicted serologically owing to the absence of an antithetical antigen,

We discuss LS-forbidden Delta S = 2 transitions of Fe Pi that appear as strong lines in ultraviolet stellar and laboratory spectra. The lines occur because of indirect lever mixing-two close energy levels, w(2)P(3/2) and x(6)P(3/2), are mixed through a third level acting as a catalyst. In transition multiplets, that involve either the w(2)P(3/2) or the x(6)P(3/2) level the normal component is acco

The reactions between chalcocite, synthetic copper(I) sulfide, acanthite and synthetic silver(I) sulfide, and aqueous and acetone solutions of potassium ethylxanthate have been studied. Qualitative analysis of the ethylxanthate species present on the surfaces of the sulfide minerals and the synthetic metal sulfides has been made by means of diffuse reflectance infrared Fourier transform (DRIFT) sp

This article describes the first Swedish experience with fertility preserving surgery according to the technique of Dargent. Minimally invasive methods gain acceptance in the treatment of other tumours and this method seems to treat adequately and preserve function. The literature is reviewed and discussed. In Sweden about 25-40 women under 30 years of age are each year diagnosed with cancer of th

In this thesis we study the critical Ginzburg-Landau action, defined on fields in the plane which are allowed to have a finite number of singularities. We show that a topological invariant, the degree, can be defined under the assumption of finite action only. The action is bounded below by a constant times the degree, and the fields which realize this lower bound satisfy a first order differentia

Two types of glassy carbon (GC) powder (i.e., Sigradur K and Sigradur G) have been mixed with mineral oil to obtain glassy carbon paste electrodes (GCPE's). The electrochemical behavior of such electrodes at different percentages of glassy carbon has been evaluated with respect to the electrochemistry of ferricyanide as revealed with cyclic voltammetry and the best paste composition was chosen. GC

Popular Abstract in Swedish I denna avhandling studeras en resonant omvandlare. Detta är en elektrisk krets som amvandlar likspänningar från en nivå till en annan. För att styra detta system, måste man förstå dess egenskaper. Min uppgift har varit att undersöka huruvida systemet innehåller s.k. gränscykler (självsvängningar) respektive chattering (extremt snabba självsvängningar). Vissa av dessa gIn this thesis existence and uniqueness of limit cycles are shown for a resonant converter, by extending Poincaré-Bendixson theory to non-smooth vector fields. We discuss relevant control theory and the role of simulations.

Can a deliberate enhancement of the natural uptake of atmospheric carbon dioxide in forests and agricultural lands contribute to the efforts to mitigation anthropogenic climate change? This is a question that has generated a great deal of debate and controversy since the inception of the multilateral climate negotiations in the early 1990s. This thesis offers an analysis of how this debate has pla
