Surveys on attitudes towards legalisation of euthanasia: importance of question phrasing

Aim: To explore whether the phrasing of the questions and the response alternatives would influence the answers to questions about legalisation of euthanasia. Methods: Results were compared from two different surveys in populations with similar characteristics. The alternatives "positive'', "negative'', and "don't know'' (first questionnaire) were replaced with an explanatory text, "no legal sanct

Biophysics of viral infectivity: matching genome length with capsid size.

In this review, we discuss recent advances in biophysical virology, presenting experimental and theoretical studies on the physical properties of viruses. We focus on the double-stranded (ds) DNA bacteriophages as model systems for all of the dsDNA viruses both prokaryotic and eukaryotic. Recent studies demonstrate that the DNA packaged into a viral capsid is highly pressurized, which provides a f

Electron microscopy of some molybdenum oxide phases after use as catalysts in oxidative ammonolysis and ammoxidation of toluene

Five molybdenum oxide samples, subjected to conditions of oxidative ammonolysis and ammoxidation of toluene at 450 and 460°C, respectively, have been characterized using X-ray diffraction, scanning and transmission electron microscopy, and specific surface area measurements. In oxidative ammonolysis, the relatively large, freshly prepared MoO3 crystals are reduced to smaller MoO2 crystals with a c

Comparison of different chamber techniques for measuring soil CO2 efflux

Twenty chambers for measurement of soil CO2 efflux were compared against known CO2 fluxes ranging from 0.32 to 10.01 mumol CO2 m(-2) s(-1) and generated by a specially developed calibration tank. Chambers were tested on fine and coarse homogeneous quartz sand with particle sizes of 0.05-0.2 and 0.6 mm, respectively. The effect of soil moisture on chamber measurements was tested by wetting the fine

Consumption of vegetables, fruit and other plant foods in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts from 10 European countries

Objective: To describe and compare the consumption of the main groups and subgroups of vegetables and fruits (V&F) in men and women from the centres participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: Cross-sectional analysis. Dietary intake was assessed by means of a 24-hour dietary recall using computerised interview software and standardised pro

Channel models for ultrawideband personal area networks

This article describes the modeling of ultra-wideband wireless propagation channels, especially for the simulation of personal area networks. The IEEE 802.15.3a standards task group has established a standard channel model to be used for the evaluation of PAN physical layer proposals. We discuss the standard model, the measurements that form its basis, and the possibilities for future improvements

Identification of novel transcription factor-like gene from human intestinal cells

Intestinal crypt epithelial T84 cells form luminal structures and differentiate to intestinal enterocyte-like cells in response to IMR-90 fibroblast-secreted transforming growth factor-beta when grown within three-dimensional collagen gel. In search of TGF-beta regulated genes involved in this differentiation process, we isolated a TGF-beta downregulated cDNA, human homologue of rat apoptosis anta

Lower Urinary Tract Symptoms in Stroke Patients

The overall aims of this thesis were to investigate the prevalence, severity and bother of Lower Urinary Tract Symptoms (LUTS) in a clinical sample of stroke patients and to evaluate the effect of pelvic floor muscle training (PFMT) in women with urinary incontinence after ischemic stroke. The thesis consisted of 6 articles based on 4 studies and a review. In the first study (Paper I), the Danish

Endoglin is not critical for hematopoietic stem cell engraftment and reconstitution but regulates adult erythroid development

Endoglin is a transforming growth factor-beta (TGF-beta) accessory receptor recently identified as being highly expressed on long-term repopulating hematopoietic stem cells (HSC) However, little is known regarding its function in these cells. We have used two complementary approaches toward understanding endoglin's role in HSC biology: one that efficiently knocks down expression via lentiviral-dri

Lifetime Measurements of Normally Deformed and Superdeformed States in 82Sr

Lifetimes of a superdeformed band in Sr-82 were measured with the centroid shift method. The measured average quadrupole moment of this band corresponds to a quadrupole deformation of beta(2) approximate to 0.49, which is slightly smaller than both the theoretical prediction, and the measured deformation of the SD band in the neighboring isotone Zr-84. Lifetimes of high spin states of three normal

Sensegiving as mise-en-sens - The case of wind power development

In seeking to advance the understanding of the production, diffusion and negotiation of meaning in and between organisations, we introduce below the notion of mise-en-sens. Mise-en-sens refers to the performing art term of mise-en-sce` ne and builds on the French term sens denoting meaning as well as direction. Starting from a qualitative analysis of how Swedish wind farm developers manage the per

Comparison of 'pattern recognition' and logistic regression models for discrimination between benign and malignant pelvic masses: a prospective cross validation

OBJECTIVES: To test prospectively the diagnostic performance of two logistic regression models for calculation of individual risk of malignancy in adnexal tumors (the 'Tailor model' and the 'Timmerman model'), and to compare them to that of 'pattern recognition' (subjective evaluation of the gray-scale ultrasound image and color Doppler ultrasound examination). DESIGN: Consecutive women with a pel

Point interactions: PT-Hermiticity and reality of the spectrum

General point interactions for the second derivative operator in one dimension are studied. In particular, cal PT-self-adjoint point interactions with the support at the origin and at points +/-l are considered. The spectrum of such non-Hermitian operators is investigated and conditions when the spectrum is pure real are presented. The results are compared with those for standard self-adjoint poin
