The need to reduce CO2 emissions from fossil-fuel based power production creates the need for new power plant solutions where the CO 2 is captured and stored or reused. Oxygen Transfer Membrane (OTM) is the key component of oxy-fuel combustion processes as pure oxygen is usually required to process reactions (e.g. Natural Gas Combined cycle NGCC, Pulverised Coal-fired power plants PC-plants, Integ

Popular Abstract in Swedish Avhandlingens bidrag ligger inom området för Markov regimskiftesmodeller i tidsserieanalys. Den består av fem separata uppsatser som specifikt undersöker två statistiska frågeställningar, samt applicerar metodologin på fyra olika makroekonomiska områden. De två huvudsakliga statistiska bidragen rör (i) utvecklandet av ett flexibelt test baserat på simulering för att utrThis dissertation studies statistical properties and applications of the Markov switching models for economic time series in five separate papers. The two main statistical themes are (i) the task of choosing the number of states to use in the model, and (ii) inference on time-varying transition probabilities. Our empirical applications span a wide array of topics in international finance and macro

The path and termination point for the rapid proton-capture (rp) process above Ni-56 is uncertain due to a lack of knowledge of nuclear properties, especially masses, near the proton drip line. To address this need we have begun a program to measure masses along the rp-process path in the A similar to 60-80 region using beta-gamma coincidence spectroscopy, Q(EC) values derived from beta (+) spectr

Only a small number of protein homologues cause the majority of allergies. There is no consensus structure or other obvious common denominator discriminating the few proteins that are allergens from thousands of other, non-allergenic proteins. By database sequence homology searching, we here show that to date known allergen sequences have no or few bacterial homologues, in contrast to randomly sel

Purpose: Antimuscarinic agents, which are used in to treat urgency and urge incontinence, have well-known effects on peripheral muscarinic receptors. However, some currently used drugs may have effects on muscarinic receptors in the brain and/or spinal cord involved in voiding control. We tested if muscarinic receptors within the central nervous system mediate a tonic excitatory influence on voidi

The incidence of moderate visual impairment and blindness due to diabetic retinopathy was studied 5 years after introducing a screening system for early detection of treatable retinopathy. Photocoagulation was performed in patients with clinically significant macular oedema, severe preproliferative, and proliferative retinopathy. Eighty-eight percent of 470 Type 1 and 88% of 388 Type 2 diabetic pa

National goals regarding sustainable development from the Swedish government were decisive in the planning process when the newly built city district Western Harbour was established in the city of Malmo, Sweden. A systems analysis was used as a tool for evaluating different collection and treatment systems. This type of analysis does not include more subjective factors such as acceptance of organi

The impossibility results of Bovens and Hartmann (2003, Bayesian epistemology. Oxford: Clarendon Press) and Olsson (2005, Against coherence: Truth, probability and justification. Oxford: Oxford University Press.) show that the link between coherence and probability is not as strong as some have supposed. This paper is an attempt to bring out a way in which coherence reasoning nevertheless can be j

Experimental data for through-drying of tissue at intensities comparable to industrial conditions arc presented. The study covers three basis weights, 20, 30 and 40 g/m(2), dried at drying air temperatures of 100, 150 and 200 degrees C. Unlike most experimental data on through-drying in the literature, the experiments in this study were performed under conditions of constant pressure drop across t

Allt sedan demonstrationerna mot WTO i Seattle har den globala rättviserörelsen uppmärksammats för att den har sammanfört aktivister från disparata rörelsemiljöer, i gemensamma protester mot den ekonomiska globaliseringens effekter och de globala organ som anses driva fram denna utveckling. I denna artikel diskuteras hur dessa mobiliseringar kan förstås utifrån gängse teorier om "nya sociala rörel

A short overview of eta and eta' decays is given with an emphasis on what can be learned for the strong interaction from them. The talk consists of a short introduction to Chiral Perturbation Theory, a discussion of eta -> 3 pi beyond p(4) and some of the physics involved in eta' -> eta pi pi, 3 pi as well as an overview of anomalous processes.

The variable region 1 to 3 (V1-V3) of the HIV-1 envelope plays an important role in coreceptor usage. Early in infection HIV- 1 is using CCR5 as coreceptor to enter target cells (R5 viruses) whereas viruses using CXCR4 as coreceptor (X4 viruses) may appear later in infection. This broadening or switch in coreceptor usage is associated with progression to AIDS. In my thesis work, we have compared t

We report a novel system for time-resolved diffuse remission spectral measurements, based on short light continuum pulses generated in an index-guided crystal fiber, and a spectrometer-equipped streak camera. The system enables spectral recordings of absorption and reduced scattering coefficients of turbid media in the wavelength range 500 - 1200 nm with a spectral resolution of 5 nm and a tempora

Rewritable Reference Attributed Grammars (ReRAGs) is a recently developed compiler-compiler technology based on object-orientation, aspect-orientation, reference attributed grammars, and conditional rewrites. In this paper we describe our experiences from using ReRAGs for implementing Java compilers. We illustrate how the usage of ReRAGs renders a rather compact, yet easy-to-understand and modular

This paper presents a computational study of the combustion process of wood pellets in a small-scale grate fired furnace. The objectives were to obtain detailed information on the combustion characteristics and NO formation in the furnace, and to examine the effect of secondary air on the combustion process. The simulation results were compared with experimental data in terms of flame temperature
