The article is based on the string-hypothesis, which has important scientific consequences. Science has meant to associate the notion of number with the strict operation of counting. However, recent account of string-theoretical approaches is sharply distinguishing ”number” from ”magnitude”. In studying ”spinning” strings in the context of language, it is shown that rotation is a valid concept. Fo
Popular Abstract in Swedish Studiens övergripande mål är att beskriva olika användningar « seul » och « seulement », och att förklara dessa användningar inom en generativ ram. Efter första kapitlets introduktion presenteras ett antal tidigare studier i det andra och tredje kapitlet. Fjärde kapitlet redovisar ett empiriskt material med exempel på seul och seulement, tagna från dagspressen. Den empiThe overall aim of this study is to describe a number of different uses of the French "seul" and "seulement", and to account for the observed differences within a generative framework. After an introductory chapter, chapters two and three present a survey of earlier studies. The fourth chapter concerns an empirical study of authentic occurrences of "seul" and seulement", drawn from the press. The
Multi-level governance is a term that is commonly used to characterize the nature of the European Union. In this article we argue that multi-level governance requires a research focus on negotiations and networks. Our focus is on day-to-day negotiations rather than ``history-making'' decisions, and we proceed from the assumption that negotiations vary in character across issue areas. After discuss
I samband med byggandet av den nya järnvägssträckningen mellan Landskrona och Helsingborg byggdes kring år 2000 flera nya pågatågsstationer både längs den nya järnvägssträckningen men även längs med den tidigare järnvägen. Dessa nya stationer som placerades på orter som tidigare helt saknat tågtrafik ger en möjlighet att jämföra utvecklingen på dessa orter med utvecklingen på andra liknande orter.
A Swedish family with choroideremia and a deletion of the CHM gene has been studied with ophthalmological examination, full-field electro-retinography, and DNA analysis in order to characterize the phenotype of the disease. Although all four patients studied had a complete deletion of the gene, they showed a considerable variability regarding the phenotype, including the electroretinogram tracings
Histone H I conjugated superparamagnetic nanoparticles were assessed for their ability to work as magnetic tracers in conjunction with the relative magnetic permeability metre (MPM-100) for the detection and quantification of DNA (deoxyribonucleic acid). The method employed was based on the electrostatic adsorption of DNA (analyte) to amino group derivatised silica (carrier) and subsequent binding
InP nanowires are fabricated by organo-metallic vapour phase epitaxy and studied via photoluminescence measurements performed on single nanowires, finding evidence of state filling with increasing excitation power density. To increase flexibility in fabrication technology we developed a wet chemical procedure to grow a CdS shell on these wires. In these InP-CdS wires the luminescence efficiency wa
1. A new methodological approach for detailed study of the organization of the cerebellar corticonuclear projection was evaluated in barbiturate-anaesthetized cats. Extracellular field potentials were simultaneously recorded in nucleus interpositus anterior and in the forelimb area of the C3 zone, at the cerebellar surface. On electrical and natural stimulation of the forelimb skin, the evoked pos
We propose a scheme for a complete reconstruction of one- and two-particle orbital quantum states in mesoscopic conductors. The conductor in the transport state continuously emits orbital quantum states. The orbital states are manipulated by electronic beam splitters and detected by measurements of average currents and zero frequency current shot-noise correlators. We show how, by a suitable compl
The aim was to study if neural grafts placed brain infarcts could improve functional recovery. The middle cerebral artery was occluded (MCAO) in 19 spontaneously hypertensive rats. Nine rats were sham operated. Twelve to 16 days after the ischemic insult, 9 of the MCAO rats received transplants of dissociated fetal neocortical tissue (MCAO-T) and 1, 3 and 6 months after transplantation surgery, th
In the first part of this thesis, measurement and registration procedures of occlusal interferences and their inter and intraobserver variability were evaluated. In the second part of this thesis, the short and long-term effect of occlusal adjustment therapy was prospectively assessed in a controlled clinical trial in a selected group of 50 patients with myogeneous craniomandibular disorders (CMD)
This article deals with how Swedish welfare authorities, governmental as well as municipal, performed personal case studies during the period 1940 to 1970. The visits at home are focused, as a mean of the authorities to generate truth of the inquired woman. The home visit was part of a personal case inquiry, perhaps initiated from the authorities to create basic data for decision-making. The examp
The article presents two Matlab-based tools for analysis andsimulation of real-time control systems: Jitterbug andTrueTime.Jitterbug allows the user to compute aquadratic performance criterion for a linear control system undervarious timing conditions. The control system is described using anumber of continuous- and discrete-time linear systems. Astochastic timing model with random delays is used
Several poly (dimethylsiloxanes) (PDMS) copolymers of dimethylsiloxane (DMS) with ethylene or propylene oxide were tested as artificial carriers for the delivery of oxygen to biological systems. Copolymers with a DMS content of 33% or lower enhanced glucose oxidation by 200% in contrast to the 25% increase produced by the same concentration of perfluorodecalin. When 0.05% of the copolymer with 18%
