A method of separately quantifying organic and inorganic 14C compounds present in spent ion-exchange resins and process water from nuclear power reactors has been developed. Extraction of carbon compounds is accomplished by means of acid stripping (inorganic 14C) and subsequent wet oxidation (organic 14C) or by N2 purging in combination with a catalytic furnace (oxidized and reduced gaseous compou
Glycosidases are widespread among bacteria. The opportunistic human pathogen Enterococcus faecalis encodes several putative glycosidases but little is known about their functions. The identified endo-β-N-acetylglucosaminidase EndoE has activity on the N-linked glycans of the human immunoglobulin G (IgG). In this report we identified the human glycoprotein lactoferrin (hLF) as a new substrate for E
Capsule The majority of Hen Harriers Circus cyaneus that spend the winter in England are derived from the British breeding population. Aims To investigate the popular hypothesis that Hen Harriers which over-winter in England are derived principally from breeding populations in mainland Europe. Methods Demographic data were used to estimate numbers of Hen Harriers in Britain at the end of the breed
This thesis investigates the role of migration in international trade within the framework of behind-the-border trade barriers and firm behavior. In addition to the introduction, which provides a context to the analysis, it consists of four essays. The first essay, titled ‘Migration as Trade Facilitation? Investigating the Links Between International Trade and Migration,’ examines the cross-countr
Unemployment and precarity have become key features of 21st century work. Employability is presented as a solution to these issues. Individuals are exhorted to manage their employability, in order to be able to exercise choice in the labour market. While employability is individualsʼ responsibility, governments, employers and educational bodies simply provide opportunities for its development. Hig
Since May 1998 Scandinavian group researchers and social psychologists have met bi-annually for what has to be called the GRASP conference. GRASP originally stood for ”Group as Paradox”. The first five conferences were held in Linköping, Lund, Stockholm and Skövde and, again, Linköping. The sixth conference was organized at Lund University May 15-16, 2008 under the auspices of the network Organi
Footwear sole wear by natural use or artificial abrasion either increases or decreases slip resistance on floors with and without lubricant. The objectives of this paper were to study the effect of footwear sole abrasive wear on slip resistance on ice with respect to temperature, and to compare the slip resistance of abraded soles on melting and hard ice with that on lubricated steel plate. The ki
We examine wireless systems employing Rake receivers and fast scheduling over multiple users. The interactions between multipath diversity, multiuser diversity, and the feedback delay are investigated in terms of the mean signal-to-noise ratio (SNR). It is assumed that all users experience the same propagation characteristics, i.e., the same number of taps and power-delay profile (PDP). The result
Popular Abstract in Swedish En studie av konformationer och elektronövergångar i ett antal rodaniner, ett tiourinämne och ett par ditiokarbamater m.h.a. kristallografi, spectroskopi och datatekniska beräkningsmetoder.Analysis of conformations and electron transitions of 3-(alkyl or aralkyl)-5-(methyl or phenyl)rhodanines with analogues and N,N'-bis[(S)-1-phenylethyl]-thiourea have been performed by X-ray crystallography, 1H NMR, molecular mechanics, ultraviolet spectroscopy and for the chiral rhodanines, enantiomer chromatography and circular dichroism spectroscopy. The magnitude of rotational barriers has bee
Popular Abstract in Swedish En anledning till att nya växtarter uppkommer är att närbesläktade arter korsar sig med varandra. Detta har skett i alla tider. Hybridisering (korsning) mellan arter kan utöver skapande av nya arter även medföra att mindre vanliga, kanske endemiska, arter inte överlever (en endem = en art som endast finns i ett mycket begränsat geografiskt område). Detta beror på genetiIn the present thesis, I investigated the inter- and intraspecific variation in the Silene vulgaris/uniflora species-complex (the bladder campions). I have focused on the effects of past and present hybridization both on a large scale ? over the whole of Europe ? and on a local scale. Silene vulgaris and S. uniflora are perennial herbs and they are interfertile. The results from my studies sugges
Several scenarios for ethanol production, methane production (by anaerobic digestion) and co-production of these, using autumn harvested hemp as substrate, were investigated and compared in terms of gross energy output. Steam pretreatment improved the methane production rate compared with mechanical grinding. The methane yield of steam pretreated stems was similar both with and without pre-hydroly
Background NKX2-1 encodes a transcription factor with large impact on the development of brain, lung and thyroid. Germline mutations of NKX2-1 can lead to dysfunction and malformations of these organs. Starting from the largest coherent collection of patients with a suspected phenotype to date, we systematically evaluated frequency, quality and spectrum of phenotypic consequences of NKX2-1 mutatio
We explore how two community-based reform models align with the World Bank's World Development Report 2004 accountability framework. Using a qualitative case study of rural Guatemalan primary schools, we examine local governance through interviews with a range of stakeholders. While both reforms appear appropriate according to the World Bank's accountability framework, especially the model giving
At the end of the eighteenth century, Edward Gibbon described the antiquarian scholars of previous generations as men of “profound learning and easy faith.” His exemplar was the Swedish polymath Olof Rudbeck, who in a series of frantic and combative tomes sought to portray Sweden as the model for Plato’s Atlantis and the seething cultural cauldron from which Western civilization had emerged. A Pil
The average charge states of Pb-188 and No-252,No-254 ions in dilute helium gas were measured at the gas-filled recoil separator TASCA. Hydrogen gas was also used as a filling gas for measurements of the average charge state of No-254. Helium and hydrogen gases at pressures from 0.2 mbar to 2.0 mbar were used. A strong dependence of the average charge state on the pressure of the filling gases was
