Leaching and tracer experiments in batches at L/S 20 were performed with 3-month-old MSWI bottom ash separated into eight different particle sizes. The time-dependent leaching of major elements (Ca2+, K+ Na+, Cl- and SO4-2) was monitored for up to 747 It. Physical properties of the particles, the specific surface (BET), pore volume and pore volume distribution over pore sizes (BJH) were determined

The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial investment costs. A life cycle approach could improve both the economic and environmental performance since the energy use would decrease. Currently, there is a lack of knowledge, models and tools for determining the life cycle cost (LCC) for

We present the joint maximum likelihood (ML) symbol-time and carrier-frequency offset estimator in orthogonal frequency-division multiplexing (OFDM) systems. Redundant information contained within the cyclic prefix enables this estimation without additional pilots. Simulations show that the frequency estimator may be used in a tracking mode and the time estimator in an acquisition mode.

The current development debate emphasizes national ownership of the development agenda as a precondition for sustainable development and aid effectiveness. Vietnam is often held up as a good example of strong ownership. Yet, the ownership concept is not clearly defined or understood due to a lack of empirically rooted evidence and analysis. This study examines the key elements of development owne

This article reviews the contemporary literature related to tamsulosin, which is now the most widely used alpha antagonist in treating benign prostatic hyperplasia. The primary emphasis of this article is on the clinical data that exist related to this agent. Currently, there are no adequate studies that effectively compare existing agents for the treatment of benign prostatic hyperplasia using a

Popular Abstract in Swedish Avhandlingen innefattar 5 fristående artiklar samt en slutlig sammanfattning av samtliga arbeten. Arbetet behandlar textilproduktion under yngre järnålder framförallt vikingatid. Textilproduktionen har beaktats utifrån de textilredskap som påträffats vid utgrävningar av bosättningar i Skåne, Mälardalsområdet samt Birka, Sverige och Hedeby nuvarande Tyskland. Redskapen oThe initial aim of the present PhD thesis was to develop the method of classification for textile tools to facilitate the study of textile production in an archaeological context. The thesis consists of five separate projects and a concluding summary. The study covers the late Iron Age, mainly the Viking Period. Geographically, the study covers the regions of Scania, in S.W. Sweden, with seven set

Background. Increased levels of nitric oxide (NO) and the exudations of plasma proteins to the airway lumen have both been considered characteristics of airway inflammation. The aim of the present study was to investigate a possible relationship between nasal NO concentrations and acutely induced exudative inflammation of the nasal mucosa. Methods: Twelve healthy non-allergic subjects participated

The linearly constrained minimum variance (LCMV) method is an extension of the classical minimum variance distortionless response (MVDR) filter, allowing for multiple linear constraints. Depending on the spatial filter length and the desired frequency grid, a direct computation of the resulting spatial beampattern may be prohibitive. In this paper, we exploit the rich structure of the LCMV express

Traffic safety work needs different methods and tools in order to choose and evsaluate traffic safety measures. The thesis contributes to this problem by presenting and visualizing a method which describes the traffic safety situation in several dimensions. The method used to describe the traffic safety problem shows the potential of a simultanous presentation and evaluation of these dimensions an

Recombinant adeno-associated virus serotype 2 (rAAV2) vector has been widely employed for gene therapy. Recent progress suggests that the new serotypes of AAV showed a better performance than did AAV2 in normal tissues. Here, we evaluate the potential role of human vascular endothelial growth factor (VEGF) gene transfer using rAAV vector pseudotyped with serotype I capsid proteins (rAAV1) in the t

The thesis analyzes the everyday life of women and men in a neighbourhood planned for low-income housing in the ourskirts of the capital San José in Costa Rica. The research uses an everyday life perspective and shows how gender organization leads to a division of labour and a use of space that differentiate between women and men's activities. There are space use patterns that reflect the existing

A series of bioassay experiments were performed from spring to autumn in a small dimictic lake (Deep Pond, Massachusetts) to examine the potential for bacterial growth limitation by organic carbon (glucose), inorganic nutrients (ammonium or phosphate), or both. The experiments demonstrated that phosphorus was the primary element limiting bacterial growth in Deep Pond during a large part of the sum

By observing and analyzing the influence of the therapist on the family as well as interactions between family members, the encounter with a family in a medical setting can serve to improve the health of its members, by improving their ability to use their own resources. This method of focusing on the interaction between individuals in a family or other systems has been a valuable addition to medi

Twenty patients who underwent early aneurysm surgery--that is, surgery within 72 hours after rupture--underwent further follow-up examination including magnetic resonance imaging (MRI) of the brain and a comprehensive neuropsychological assessment. Significant statistical correlation between tissue loss as seen on a late MRI scan and neurobehavioral deficits could not be established. Among 9 patie
