The transition rates of the intercombination lines 2s2p(3 5)S(2)(0)-->2s(2)2p(2 3)P(1,2) are computed using a systematic configuration interaction method (SCIV3). The calculated lifetime of the upper S-5(2)o, level is in excellent agreement with a recent experiment. The branching ratio of the two lines is very different from earlier, less accurate theoretical values.
An hepatitis A epidemic among 36 persons, mainly drug addicts, occurring over an 18-week period, is described. There were indications that smuggling and transportation of narcotic drugs in the rectum started the outbreak, either through direct contamination of the drug or manipulation of the drug resulting in contaminated fingers.
The LUCS Haptic Hand I together with a set of haptic models is the first in a series of projects aimed at studying haptic perception for building several robotic hands together with cognitive computational models of the corresponding human neurophysiology. The haptic systems have been trained and tested with a set of objects consisting of balls and cubes, and the activation in the modules correspo
The kinetics of dipolar nonradiative energy transfer (DET) between dyes confined to the core−corona interface region of poly(isoprene-b-methyl methacrylate) block copolymers (PI−PMMA) in acetonitrile was analyzed using a new distribution model for energy transfer in spherical micelles. The distribution of block junction points was described by the model of Helfand and Tagami (HT) for the strong se
This thesis deals with techniques for the full integration of radio frequency (RF) transmitter with CMOS technology. The theory and implementation of high performance digital-to-analog converters (DACs) for radio frequency (RF) transmitters have been studied. A linear interpolation DAC architecture is proposed. By employing the linear interpolation, the attenuation of DAC's image components is sig
Glucagon, secreted from pancreatic islet a cells, stimulates gluconeogenesis and liver glycogen breakdown. The mechanism regulating glucagon release is debated, and variously attributed to neuronal control, paracrine control by neighbouring beta cells, or to an intrinsic glucose sensing by the a cells themselves. We examined hormone secretion and Ca2+ responses of a and b cells within intact roden
The focus of this article is on the legal profession's visual self-image of legal authority. It takes a departure from the themes of visual legal communication and discusses the relationship between text and pictures in the legal domain. The discussion concludes with a reflection on the consequences of the modern pictorial evolution. Bearing this discussion in mind, will the development of the ICT
We investigate spin-dependent interband magnetotunneling processes in strained broken-gap resonant tunneling structures made from InAs, AlSb, and GaSb, which are promising materials for quantum devices. InAs/AlSb/GaSb/InAs/AlSb/GaSb double-barrier structures grown on both InAs and GaSb are considered. Transmission coefficients for interband tunneling processes from individual eigenstates in the In
Multiple windows have been used in spectrum analysis to reduce variance. In this paper, a multiple-window approach is suggested in cepstrum analysis, where the period of the system response should be estimated. The logarithm of the spectrum as well as the liftering are approximated by a division of two multiple-window spectra. The method is useful especially in the case of short periods of the per
Background Both gastrectomy (GX) and ovariectomy (OVX) induce osteopenia in man and experimental animals. The present study addresses the question - can alendronate, estrogen or parathyroid hormone (PTH) be used to treat established GX- or OVX -evoked osteopenia? Methods Rats were GX-, OVX- or SHAM-operated 8 weeks before starting the treatment with drugs. Each group was then treated for 8 weeks
Popular Abstract in Swedish I denna avhandling studeras korruption och mutor som i första hand sociala och moraliska, snarare än ekonomiska, fenomen. Vilka beskrivningar och tolkningar ger svenska och danska biståndsarbetare av sina möten med vardaglig korruption? Hur fördömes, ursäktas eller rättfärdigas användandet av mutor? Går det att tala om en etikett för mutor, och hur ser denna i så fall uIn this dissertation, corruption and bribery are investigated as social and moral, rather than economic, phenomena. The analysis concentrates on the ways in which Swedish and Danish aid workers describe their experiences of everyday or 'petty' corruption. How do they view their encounters with everyday corruption in developing countries? In what ways are bribes condemned, excused, or justified? Wh
The dependence of charges accumulated on a quantum dot under an external voltage bias is studied. The charge is sensitive to the changes of number of filled levels and the number of conducting levels (channels). We clarify that there are two possible outcomes of applying a bias. (a) The number of conducting channels increases, but the number of filled levels decreases. (b) The number of filled lev

Dynamic changes in structure and morphology during the heating of iron powder to high temperatures have been studied in situ in an environmental scanning electron microscope (ESEM). The results have shown that the presence of lubricants leads to the formation of ferrite needles at about 500ºC. At higher temperatures, the recrystallization of alpha-iron, followed by the nucleation and growth of gam
Incorporating bowel into the urinary tract sets the stage for a potentially dangerous situation for the upper part of this tract. Obstruction, reflux and chronic bacteriuria may develop, all of which can all be detrimental. Most reports on renal function have used IVP and serum creatinine only, methods which are inadequate for proper assessment. Long-term follow-up of patients with ileal conduit d
The NOPEX experimental campaigns dealt with the land-surface-atmosphere exchange of momentum, heat, water and CO2 on local and regional scales. In this paper emphasis is put on the NOPEX experiences with respect to the spatial integration of fluxes of momentum, heat, humidity and CO2 over the mosaic of forest, agricultural land, lakes and mires that make up the southern part of the NOPEX area. It
