Soil water movement estimated from isotope tracers
The natural isotope oxygen-18 and artificially injected tritium are used for studying the percolation of soil water. Particle velocity, progression rate and soil moisture flux are distinguished from each other. Water particle velocities and seasonal groundwater recharge are determined in glacio-fluvial deposits and in till soils. In the glacio-fluvial deposits of the Uppsala Esker it is found that
Rewriting in operads and PROPs
This paper is an informal collection of observations on how established rewriting techniques can be applied to or need to be adapted for use in non-associative algebras, operads, and PROPs.
Subtle sequence differences in a turnour-associated peptide epitope translate into major changes in antigenicity
Antigenicity, the ability to bind to members of repertoire of diverse immune receptors, is a concept that is poorly characterised with respect to its defining parameters. To learn more about its makeup, we have investigated the ability of two peptides with highly related sequences, derived from the tumour-associated antigen mucin-1, to recruit in vitro members from a large naive repertoire of synt
Extreme value theory for queues via cycle maxima
The present state of extreme value theory for queues is surveyed. The exposition focuses on the regenerative properties of queueing systems, which reduces the problem to the study of the tail of the maximum $overline X( au)$ of the queueing process ${X(t)}$ during a regenerative cycle $ au$. For simple queues, methods for obtaining the distribution of $overline X( au)$ both explicitly and asymptot
Describing non-Fickian water-vapour sorption in wood
Moisture transport and sorption in wood may not be accurately described by Fick's law of diffusion. The problem of making a model of non-Fickian behaviour (NFB) for wood is discussed. Some measurements in which NFB in wood is clearly seen are also reviewed. Four criteria, which must be satisfied by a model describing sorption in wood cell walls, are presented: (1) the model should not only describ
Informationsteknik och organisatorisk förändring - Teknik, organisation och produktivitet i svensk banksektor 1975-2003
Popular Abstract in Swedish Syftet med avhandlingen är att analysera den tekniska och organisatoriska ut¬vecklingen inom svensk banksektor under perioden 1975-2003 samt att se hur för¬ändringar i dessa två variabler påverkat produktivitetsutvecklingen. Utgångspunkten för analysen av den tekniska och organisatoriska förändringen är att det föreligger ett komplementärt förhållande mellan informationThe purpose of this thesis is to investigate the relation between technological and organizational change in the Swedish banking sector from 1975 to 2003. Besides analyzing the changes in these two variables the effects of the interaction on productivity changes in the sector are examined. The use of the concept of complementarity as a basis for analyzing the interaction between technological and
Effects of restricted diffusion in a biological phantom: a q-space diffusion MRI study of asparagus stems at a 3T clinical scanner
Introduction The aim of this work was to study the effects of restricted diffusion in a biological phantom consisting of green asparagus stems using q-space MRI at a clinical scanner. Method Measurements of the full width at half maximum (FWHM) of the displacement distribution were performed with varied diffusion time (T d). The accuracy of the measurements was investigated with respect to the deg
A theoretical study of the copper–cysteine bond in blue copper proteins
The accuracy of theoretical calculations on models of the blue copper proteins is investigated using density functional theory (DFT) Becke's three-parameter hybrid method with the Lee–Yang–Parr correlation functional (B3LYP) and medium-sized basis sets. Increasing the basis set to triple-zeta quality with f-type functions on all heavy atoms and enlarging the model [up to Cu(imidazole-CH3)2(SC2H5)
Concord and Conflict: the Hui Communities of Yunnan Society in a Historical Perspective
This dissertation studies the historical relation between the Muslim minority and the non-Muslim majority in Yunnan with a combined method: historical criticism supplemented by ethnological interpretation. This relation manifests in history dynamic and dialectical characteristics: concord and conflict. Concord can be found in the stable and balanced periods in the relevant socio-cultural aspects o
Unnoticed relationships: Do consumers experience co-branded products?
This paper takes an interpretive approach to consumers' experiences with co-branded products. While the intended benefits of combining brands in a co-branded product are obvious for the brand owners, it is far from clear that consumers experience these products as co-branded. Results indicate that consumer experiences with co-branded products vary from being very rich to nonexistent. The findings
Cartilage and bone macromolecules in knee joint synovial fluid in rheumatoid arthritis: relation to development of knee or hip joint destruction
OBJECTIVE: To examine the hypothesis that aggrecan, cartilage oligomeric matrix protein (COMP), and bone sialoprotein (BSP) concentrations in synovial fluid could provide information on variations of progression of joint destruction in rheumatoid arthritis. METHODS: Aggrecan, COMP, and BSP were quantified by enzyme linked immunosorbent assays in longitudinally collected knee joint synovial fluid s

Cerebral complications detected by EEG-monitoring during neonatal intensive care
The report describes the clinical use and value of continuous EEG-monitoring during different clinical circumstances that are not usually related to changes in EEG. Three infants with pneumothorax, hypoglycaemia, and severe hyaline membrane, respectively, are presented.
Dependence on oil chain-length of the curvature elastic properties of nonionic surfactant films: Droplet growth from spheres to a bicontinuous network
Using NMR self-diffusion and H-2-NMR relaxation experiments, we have investigated growth of oil-in-water microemulsion droplets when spontaneous curvature is lowered, starting at emulsification failure boundary. We compare two ternary nonionic microemulsion systems, containing penta-ethylene glycol dodecyl ether (C12E5), and decane or hexadecane, at same surfactant-to-oil ratio and approximately t
Notes on the Cretan mistletoe, Viscum album subsp creticum subsp nova (Loranthaceae/Viscaceae)
Viscum album subsp. creticum, known from two mountain areas of E. Crete, is described as new to science. It combines features of the two presently accepted conifer mistletoes, resembling the fir parasite, subsp. abietis, in gross morphology but genetically (by nrDNA ITS sequence data) close to the pine parasite, subsp. austriacum, while differing from either in hypocotyl shape and nucleotide seque
Corrosion of steel in concrete
The research work that is presented in this thesis aims at mapping out the various mechanisms which control the process of steel corrosion in concrete. The process of corrosion is illustrated with a schematic model where the service life is divided into a period of initiation and a period of propagation. The time up to the initiation of the corrosion process is determined by the flow of penetratin
