In this paper, I propose a relevance-theoretic account of the particles le, guo and zhe in Mandarin Chinese. Though conventionally regarded as aspect markers, on closer inspection they seem to contribute to a range of interpretations that cannot be subsumed under a semantic category or a specific temporal representation. The explanatory model presented in this paper builds upon relevancetheoretic

Differences in the incidence of hip fractures have been reported between urban and rural areas. In this population-based study the characteristics of fracture patterns between the city of Malmo and the nearby rural district of Sjobo were compared. A total of 782 individuals in Malmo and 486 in Sjobo were invited to participate. Fracture history for all invited was registered. The odds ratio for fr

Over the years, there has been much debate regarding the conformational behavior of flexible polyelectrolytes with electrostatic interactions described by the D bye-Huckel approximation. In particular, the electrostatic persistence length has been reported to depend both quadratically and linearly on the screening length as well as having no consistent power-law dependence at all. On the basis of

The phylogeny of two lichens, Cetraria obtusata from the Alps and Coelopogon epiphorellus occurring in the southern hemisphere is studied. A DNA-matrix based on ITS 1 and ITS 2 sequences of the rDNA is compared with a data set composed of morphology and secondary chemistry characters in phylogeny analyses using PAUP 4.0. The two data sets were entirely congruent. Neither Cetraria obtusata nor Coel

CONCLUSIONS: The results of the present study suggest that the pancreas and parotid glands both respond with hypoplasia during absence of food in the digestive tract and with hyperplasia following pancreatico-biliary diversion (PBD). Factors other than cholecystokinin (CCK) are, however, involved in the effects on the parotid glands, since infusion of CCK-8S and devazepide was without influence. B

The main topic of the thesis is the connection between representation theory and special functions. We study matrix elements, coupling coefficient, and recoupling coefficients for the simplest Lie and quantum groups. We show that a large number of multivariable orthogonal and biorthogonal polynomials occurring in the literature may be obtained as coupling coefficients (generalized Clebsch-Gordan

The purpose of this report is to present a critical review of research and practice based knowledge about factors conductive to ”good functioning” of work teams in the light of the evolving knowledge of developmental processes in groups. Conceptions of work team effectiveness are critically evaluated and new formulations presented. Factors such as two-way causality, boundary based defintions of te

The purpose of this study was to examine the effect of exacerbations on mild to moderate asthmatic patients' preference-based, health-related, quality of life scores and also to describe the effect of these exacerbations on daily life. In a survey, 100 mild to moderate asthmatic patients in the United Kingdom were asked to rate three different health marker states on a scale between 0 (death) and

Global error bounds are derived for multistep time discretizations of fully nonlinear evolution equations on infinite dimensional spaces. In contrast to earlier studies, the analysis presented here is not based on linearization procedures but on the fully nonlinear framework of logarithmic Lipschitz constants and nonlinear semigroups. The error bounds reveal how the contractive or dissipative beha

We present a logic which we call Hybrid Duration Calculus (HDC). HDC is obtained by adding the following hybrid logical machinery to the Restricted Duration Calculus (RDC): nominals, satisfaction operators, down-arrow binder, and the global modality. RDC is known to be decidable, and in this paper we show that decidability is retained when adding the hybrid logical machinery. Decidability of HDC i

Dispersion of electromagnetic waves is usually described in terms of an integrodifferential equation. We show that whenever a differential operator can be found that annihilates the susceptibility kernel of the medium, dispersion can be modeled by a partial differential equation without nonlocal operators

There is an increasing interest in new strategies for replacing animal tests in research. The use of cell cultures and integrated electrodes is seen as a promising alternative that could potentially solve this problem. In this work, we present a L-glutamate sensor based on a bienzyme redox hydrogel, capable of detecting the release of this excitatory neurotransmitter from adherently growing cells

beta-Alanine synthase catalyzes the last step in the reductive degradation pathway for uracil and thymine, which represents the main clearance route for the widely used anticancer drug 5-fluorouracil. Crystals of the recombinant enzyme from Drosophila melanogaster, which is closely related to the human enzyme, were obtained by the hanging-drop vapour-diffusion method. They diffracted to 3.3 angstr

Object. Subarachnoid hemorrhage (SAH) results in the expression of inflammatory and extracellular matrix (ECM)related genes and various G protein-coupled receptors. In the present study, the authors evaluated the time course and sequence of the transduction pathways, p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase-1 and 2 (ERK1/2), and associated transcription
