The conductive polymer poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4- phenylene vinylene) (MEH-PPV) was investigated by means of single molecule spectroscopy at 15 K. MEH-PPV single chains were deposited onto a surface from a toluene solution and covered with a polymer cap layer spin-coated from an aqueous solution for protection from air. The MEH-PPV molecules exhibited large fluorescence spectral diff
A soy protein film coating was developed and evaluated to reduce fat transfer in deep-fried foods during frying. Soy protein isolate solutions (10% SPI) with 0.05% gellan gum as plasticizer cooled after being held at 80 degrees C for 20 min provided suitable films. There was a significant fat reduction (55.12(+/-6.03)%db) between fried uncoated and coated discs of doughnut mix. The same films were
Popular Abstract in Swedish Ofärd är samhällsrisker. Riskorganisationer kan definieras som organisationer vilka genererar större samhällsrisker än traditionellt företagande. Dessa organisationer hanterar en mer omfattande kravbild än gängse företagande, en kravbild som innefattar risker för människor utanför själva verksamheten. Riskorganisationer är en del av den värdeförädling som krävs för att Risk societies are made of risk organizations. This dissertation is an ethnographic study of a risk organization, of a nuclear power plant. Risk organizations have larger demands on their organization than traditional companies have. Risk societies, to come or already present, have new political agendas. Within a risk society the major task is to reduce and distribute the negative side effects of
Popular Abstract in Swedish Syftet med avhandlingen är att undersöka bondeskapets (the peasantry)framtida existens. Analysen görs på global nivå, men framför allt på lokal nivå i samband med implikationerna av Mexikos nya jordreform från 1992. Bonden dekonstrueras i ekonomisk-och sociopolitisk aktör för att belysa hans/hennes complexitet. Försörjningsstrategier i tider då staten ersätts av markandThe thesis deals with a classical issue, that of the fate of the peasantry, in particular the process of the transformation of the peasantry. The aim is to explore whether there is a place for the smallholding peasantry in the future, or if the process of dissolution is inevitable. The discussion of this broad question is approached by first deconstructing the peasantry into economic actors and so
The role of immunoglobulin A (IgA) anti-tissue transglutaminase antibodies (IgA-tTG) as predictors of untreated celiac disease (CoD) is well documented, and the presence and levels of these antibodies are most accurately monitored with native or recombinant human antigens. However, IgA-deficient CoD patients are not identified by IgA serology, and conflicting results concerning the diagnostic vali
The anthology deals with pedagogical problems within academic teaching.
Popular Abstract in Swedish Avhandlingen innehåller fyra arbeten om några aspekter på ickelineära paraboliska ekvationer och system. I det första arbetet presenterar vi ett resultat om "quenching" vid dynamiska randvillkor. Det andra arbetet rör global existens av klassiska lösningar till vissa paraboliska system. I det tredje arbetet bestämmer vi optimala konstanter för vissa Gagliardo-NirenbergThis thesis contains four papers about some aspects of nonlinear parabolic equations and systems. Paper 1. A note on quenching for parabolic equations with dynamic boundary conditions We present a quenching result for semilinear parabolic equations with dynamic boundary conditions in bounded domains with a smooth boundary. Paper 2. On global existence for semilinear parabolic systems We presen
The process K-l3 is calculated to two-loop order (p(6)) in chiral perturbation theory (ChPT) in the isospin conserved case. We present expressions suitable for use with previous work in two-loop ChPT where the order p(4) parameters (L-i(r)) were determined from experiment. We point out that all the order p(6) parameters (C-i(r)) that appear in the value of f(+)(0) relevant for the determination of
Persistent aneurysm perfusion represents failure of endovascular repair. The leak may occur around either end of the prosthesis or through a collateral route. Most cases can be treated by endovascular means. Stents can be rotated, the prosthesis can be lengthened at either end, and collateral pathways can be occluded, all without recourse to open repair. This report describes the management of per
This paper presents an investigation of CO formation in a lean premixed propane/air turbulent flame in an afterburner configuration. A previous experiment showed that a high amount of CO was formed in the mean turbulent flame brush. To explain the high CO concentration in the flame zone, the effects of flame stretch and flame wrinkling are studied, based on an ensemble averaged laminar flamelet li
This study describes the chydorid (Branchiopoda, Anomopoda) assemblages from 66 European shallow lakes, and presents data relating the assemblages to lake type and ecological quality. Forty species, out of a total recorded European fauna of 60 species, were found in the study sites. No significant differences were found between chydorid assemblages associated with rock and plant substrata. Pattern
Popular Abstract in Swedish Tvärsektoriella nätverk mellan myndigheter, näringsliv och olika intressegrupper har tilldelats en allt större betydelse, då det varit en vanlig uppfattning att en hållbar utveckling bäst skapas genom ett gemensamt ansvar. Uppfattningarna om resultaten av dessa initiativ uppvisar dock spektakulära skillnader: från att framstå som oslagbara lösningar på de utmaningar soThe importance of cross-sectoral collaborative initiatives, that is partnerships of governments, civil society and the private sector, was elevated due to the belief that the issues of SD are a collective responsibility of all societal actors. The assessment of these initiatives is ranging dramatically; from giving them a status of an unbeatable solution for the SD challenges, to blaming them for
The report contains abstracts of master theses (examensarbete) made at the department of Automatic Control, Lund, during the academic year 1979/80. During this year 12 theses were made by 15 students. The theses are written in Swedish with an English abstract.
Conjugated polymers are becoming interesting materials for a range of optoelectronic applications. However, their often complex electronic and structural properties prevent establishment of straightforward property-function relationships. In this paper, we summarize recent results on the photophysics and excited state dynamics of conjugated polymers, in order to paint a picture of exciton formatio
Objective: To assess overall resource consumption, work capacity and quality of life of patients with multiple sclerosis in nine European countries. Methods: Information on resource consumption related to multiple sclerosis, informal care by relatives, productivity losses and overall quality of life (utility) was collected with a standardised pre-tested questionnaire from 13186 patients enrolled i
Treatment of a benzene solution of (tmeda)PdMe2 or (dppe)PdMe2 with carbon dioxide gives the corresponding methyl bicarbonate complex, (L-L)PdMe(O2COH). These were characterised by NMR spectroscopy and elemental analysis. Under strictly dry conditions no reaction was observed. Recrystallisation of the tmeda bicarbonate complex from acetone yields the corresponding eta(2)-carbonate complex, which w
Purpose: alpha-Melanocyte stimulating hormone (alpha-MSH; Fluka Chemie AG, Geneva, Switzerland) and oxytocin induce erection in rats after intracerebroventricular administration. We studied possible interactions of alpha-melanocyte stimulating hormone with mechanisms pertaining to oxytocin or nitric oxide. Materials and Methods: We used 78 anesthetized male Sprague-Dawley rats. Catheters were impl
