Shredder residues of end-of-life vehicles and white goods are a complex waste stream, which nowadays most often is disposed of at industrial landfills. This paper describes the most important findings concerning the complex composition of the landfill leachate and its on-site, year-round treatment under cold-climate conditions. A 3-year investigation has confirmed that concentrations of different

In this study, a new supercritical fluid chromatography-mass spectrometry (SFC-MS) method has been developed for the separation of nine vitamin D metabolites within less than eight minutes. This is the first study of analysis of vitamin D and its metabolites carried out by SFC-MS. Six columns of orthogonal selectivity were examined, and the best separation was obtained by using a 1-aminoanthracene

Since 2009, Japanese civil society groups have arranged exhibitions in China dealing with the so-called comfort women issue in cooperation with local Chinese organizers, including state-run war museums that function as patriotic education bases. Organizing these exhibitions has required much time and energy. A fundamental aim of these groups is to make the Japanese government compensate the victim

In order to reduce its environmental impact, the chemical industry no longer produces base chemicals such as ethylene, solely from fossil, but also from biomass-based feedstocks. However, a biomass option suitable for one region might not be as suitable for another region due to, e.g., long transport and the related environmental. Therefore, local biomass alternatives and the environmental impact

This paper concerns the use of the expectation-maximisation (EM) algorithm for inference in partially observed diffusion processes. In this context, a well known problem is that all except a few diffusion processes lack closed-form expressions of the transition densities. Thus, in order to estimate efficiently the EM intermediate quantity we construct, using novel techniques for unbiased estimatio

The article considers the importance of frontier studies in historical archaeology and discusses applicability of some of the concepts deriving from postcolonial theories for a better understanding of human relationships in the frontier zones. The conditions of frontiers and borderlands are compared with the characteristics of the “Third Space” described by Homi Bhabha as a realm of negotiation, t

Widespread implementation of cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD) in clinical settings requires improved accuracy for diagnosis of prodromal disease and for distinguishing AD from non-AD dementias. Novel and promising CSF biomarkers include neurogranin, a marker of synaptic degeneration, and YKL-40, a marker of neuroinflammation.

In this paper, a novel method for analysing a bird’s song is presented. The song of male great reed warblers is used for developing and testing the methods. A robust method for detecting syllables is proposed and a classification of those syllables as compared to reference syllables is done. The extraction of classification features are based on the use of singular vectors in different time-freque

This thesis covers different topics related to the application of pseudospectral optimization methods in the field of automatic control. Pseudospectral optimization methods solve dynamic optimization problems by discretizing the state-space, creating a discretized version of a continuous problem. The resulting discretized optimization problems are solved by standard software for nonlinear optimiza

Background In mild asthma exercise-induced bronchoconstriction (EIB) is usually treated with inhaled short-acting beta(2) agonists (SABAs) on demand. Objective The hypothesis was that a combination of budesonide and formoterol on demand diminishes EIB equally to regular inhalation of budesonide and is more effective than terbutaline inhaled on demand. Methods Sixty-six patients with asthma (>12 ye

Aims. Observational studies of the Milky Way bulge are providing increasing evidence of its complex chemo-dynamical patterns and morphology. Our intent is to use the iDR1 Gaia-ESO Survey (GES) data set to provide new constraints on the metallicity and kinematic trends of the Galactic bulge, exploring the viability of the currently proposed formation scenarios. Methods. We analyzed the stellar para

Popular Abstract in Swedish Hur går det egentligen till när beslut fattas om nya, och för skattebetalarna kostsamma, väg- och järnvägsinvesteringar? Fattas besluten på basis av objektiva utredningar och noggranna kalkyler, eller är de ett resultat av politiska förhandlingar och spel mellan olika intressen? I denna avhandling undersöks investeringsplanering som politisk beslutsprocess dels genom enInvestment planning is a decision-making process with specific characteristics. It is often seen as a rational quest for solutions that are in the public interest, and the dominant discourse tends to be technical and economic. Public documents reproduce this picture of a decision-making process based on rationalist premises where analytical methods and objective facts form the basis for decisions.

Background: Dietary fibre is fermented by the colonic microbiota to carboxylic acids (CA), with potential health effects associated in particular with butyric and propionic acid. Objective: To investigate the formation of CA in the hindgut of healthy rats fed dietary fibre from different fractions of wheat shorts, a by-product of the milling of wheat. Design: Rats were fed dietary fibre (80 g/kg f

Enterohemorrhagic Escherichia coli (EHEC) is a highly virulent pathogen that can cause diarrhea and a life-threatening disease known as hemolytic uremic syndrome. EHEC possess an array of virulence factors that can exert severe consequences in the host. Shiga toxin constitutes a key virulence factor. Enteropathogenic Escherichia coli (EPEC) is a leading cause of infant diarrhea. EHEC and EPEC are

In this paper, we introduce a time-frequency spectral estimator for smooth spectra, allowing for irregularly sampled measurements. A non-parametric representation of the time dependent (TD) covariance matrix is formed by assuming that the spectrum is piecewise linear. Using this representation, the time-frequency spectrum is then estimated by solving a convex covariance fitting problem, which also

ASHEIM B. The changing role of learning regions in the globalizing knowledge economy: a theoretical re-examination, Regional Studies. Highlighting four theoretical developments, this paper theoretically re-examines the learning region in view of the changing roles of regions in the globalizing knowledge economy: (1) from specific contexts to general regional development strategies; (2) introducing
