Popular Abstract in Swedish Lysande plast, finns det? Tanken är att att tunn plast-film skall kunna användas som ihoprullbara tunna TV- och datorskärmar, som lysdioder, som mottagare i solceller och som transistorer. Till vardags är förmodligen den vanligaste uppfattningen att plast är ett isolerande material som inte leder ström och som därför heller inte lyser. Faktum är att bara en del av plasTransient absorption laser spectroscopy and resonance Raman spectrscopy have been used to study conjugated polymers and oligomers. To extract more information the measurements have been compared to computer simulations and calculations. In order to obtain a better understanding of the role of conformational disorder in the photophysics of light-emitting, conjugated polymers the ultrafast transient

A dispersion relation for the combined effect of scattering and absorption of electromagnetic waves is presented for a large class of linear and passive material models. By invoking the optical theorem, the result states that the extinction cross section integrated over all frequencies is equal to the static limit of the extinction volume. The present paper focuses on an attempt to experimentally

Abstract An N-Heptane mechanism and a Methane/Propane mechanism have been reduced by an Automatic Reduction Tool (ART) and simulated with two different solver combinations, which solve the set of ordinary differential equations governing the time evolution of the species simultaneously with solving algebraic equations for species that can be considered to be in quasi steady state. The most succes

Objective. To study frequency of dose escalation in infliximab-treated patients and to identify possible predictors thereof. Methods. Patients with chronic arthritis initiating their first course of anti-TNF treatment with infliximab at Lund University Hospital were included in a structured clinical follow-up protocol. Information on diagnosis, drug dosage, disease duration, previous and ongoing D

To determine benefits and harms of arthroscopic knee surgery involving partial meniscectomy, debridement, or both for middle aged or older patients with knee pain and degenerative knee disease.

Objective: Metformin has been reported to reduce alpha-dicarbonyls, which are known to contribute to diabetic complications. It is unclear whether this is due to direct quenching of alpha-dicarbonyls or to an improvement in glycemic control. We therefore compared the effects of metformin versus repaglinide, an antihyperglycemic agent with an insulin-secreting mechanism, on the levels of the alpha-

The development of new techniques for detection and characterization of transient myocardial ischemia has benefited considerably from the STAFF database, acquired in patients receiving elective prolonged percutaneous transluminal coronary angiography. The present article reviews a range of techniques developed and/or evaluated on the ECG signals of this database, including techniques for exploring

To determine whether adjuvant tamoxifen treatment for breast cancer (BC) is associated with reduced contralateral breast cancer (CBC) risk for BRCA1 and/or BRCA2 mutation carriers.

The human Sushi Domain-Containing Protein 4 (SUSD4) was recently shown to function as a novel inhibitor of the complement system, but its role in tumor progression is unknown.

Popular Abstract in Swedish I avhandlingen presenteras nya teoretiska och experimentella metoder för att analysera spridning av elektromagnetiska vågor, framförallt med fokus på antenner och trådlös kommunikation. Oavsett det handlar om radio- och TV-sändningar, mobiltelefoni, trådlösa datornätverk, eller radar, så är antenner oumbärliga; de är nämligen länken mellan de elektromagnetiska vågorna oSum rules and physical limitations within electromagnetic theory and antenna theory have received significant attention in the last few years. However, the derivations are often relying on application specific and sometimes unsupported assumptions, and therefore a mathematically rigorous and generally applicable approach seems timely. Such an approach is presented in this thesis, along with exampl

The aim of this study was to determine effects on methane potential and overall sludge quality from two different sludge pre-treatment technologies (ozonation high/low dosage and thermal treatment 55/70 degrees C). In general both treatments produced increased methane potential. Thermal treatment resulted in higher chemical oxygen demand (COD)-solubilisation, while the highest volatile fatty acids

Context. Metal-rich globular clusters provide important tracers of the formation of our Galaxy. Moreover, and not less important, they are very important calibrators for the derivation of properties of extra-galactic metal-rich stellar populations. Nonetheless, only a few of the metal-rich globular clusters in the Milky Way have been studied using high-resolution stellar spectra to derive elementa

The contentious issue of identification of any early signs of the emergence of European public sphere in media is the primary topic of this paper. The qualitative analysis is focused on comparing cross-media empirical data from the previously published research in the area of the television, newspapers, and the new media (internet) which shows on more ideological than nationally based framing of t

Power production represents one fourth to one third of all CO2 emissions. Carbon Capture and Storage (CCS) in one way to approach the increasing problem with CO2 emissions from fossil fuelled power plants. The CO2 is separated, compressed and transported to a final storing site. To allow more efficient transport and to match the pressure of the final storing site, the CO2 is compressed to a superc

China has had an unbelievable economic development over the last 25 years. Their gross domestic product (GDP) has increased by more than 9% yearly. Since the middle of the 1980’s this trend has become more and more dependent on China’s private firms. China’s private firms are much more effective than their counterpart state-owned enterprises. Despite this fact, private firms are still treated very
