Experimental and theoretical investigation of an evaporative fuel system for heat engines

The evaporative gas turbine (EvGT) pilot plant has been in operation at Lund University in Sweden since 1997. This project has led to improved knowledge of evaporative techniques and the concept of introducing fuel into gas turbines by evaporation. This results in, amongst others, power augmentation, efficiency increase and lower emissions. This article presents the experimental and theoretical re

The resolution of the Nirenberg-Treves conjecture

We give a proof of the Nirenberg-Treves conjecture: that local solvability of principal-type pseudo-differential operators is equivalent to condition (Psi). This condition rules out sign changes from - to + of the imaginary part of the principal symbol along the oriented bicharacteristics of the real part. We obtain local solvability by proving a localizable a priori estimate for the adjoint opera

Foreign trade and declining pollution in Sweden: a decomposition analysis of long-term structural and technological effects

This article examines whether there exists any causal relationship between foreign trade and declining pollution in developed countries. In other words, do developed countries outsource their problems to less developed countries rather than solve them? The case study is the Swedish economy and the two environmental indicators employed are energy consumption and CO2 emissions. No causal relationshi

Comparison of different labelling index formulae used on bromodeoxyuridine-flow cytometry data

The essence of the bromodeoxyuridine (BrdUrd)-flow cytometry (FCM) technique is that cells are labelled with the thymidine analogue BrdUrd. They are then allowed to progress through the cell cycle in a BrdUrd-free environment during the postlabelling time period. At a postlabelling time shorter than the length of the S phase (Ts), cells are fixed and prepared for FCM-mediated analysis of BrdUrd an

Differentiated limits for knowability

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

Negotiations in Networks in the European Union

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

Regionaltågssatsningars effekt på fastighetsvärden - en studie av Västkustbanan i Skåne

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.

Phenotype variation within a choroideremia family lacking the entire CHM gene

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

A preliminary study on DNA detection based on relative magnetic permeability measurements and histone HI conjugated superparamagnetic nanoparticles as magnetic tracers

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

Core-shell InP-CdS nanowires: fabrication and study

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

Topographical organization of the cerebellar cortical projection to nucleus interpositus anterior in the cat

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

Quantum state tomography with quantum shot noise

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
