A compact fluorosensor using three different ultraviolet light-emission diodes as excitation sources for fiber-optic recording of fluorescence 10 spectra from samples is described. A compact integrated spectrometer with linear array wavelength recording is used, yielding a spectral resolution 11 of about 8 nm. In two system implementations ultraviolet light-emitting diodes at 300, 340 and 395 nm,

The aim of this qualitative study was to identify and analyse the experiences of Swedish local health authority occupational therapists with regard to their participation in, and the implementation of, research. Data were collected from three focus-group interviews, with five different occupational therapists in each. The interviews were taped and transcribed and thereafter analysed using broad co

Not only the argument from contingency for the existence of God but also the theistic idea that God is the metaphysical foundation of the world seem to presuppose the intelligibility and validity of the following question: Why is there anything contingent at all? However, it has been argued that, upon closer inspection, this question is a pseudo-question: a question which presupposes illegitimate

Prion protein (PrP) is an endogenous protein involved in the pathogenesis of bovine spongiform encephalopathy and Creutzfeldt-Jakob disease. Murine PrP has been reported to bind C1q and activate the classical pathway of complement in a copper-dependent manner. Here we show that various conformational isoforms (native, amyloid fibrils, and beta-oligomers) of recombinant human PrP (90-231 and 121-23

A methodology for evaluating and comparing control strategies for wastewater treatment plants was developed. The basic setup of the benchmark is described and the dynamic input data for performing the simulations are outlined. Initial results using different simulation platforms (Fortran code, Matlab/Simulink and GPS-X) are presented.

Vascular aging is described as a gradual process involving biochemical, enzymatic, and cellular changes of the vasculature and modification of the signals that modulate them. On the basis of this conception a new pathophysiological model for deeper understanding of cardiovascular risk and its treatment was introduced. The idea of early vascular aging, that is the acceleration of vascular aging see

We address the problem of transmit beamforming under channel uncertainties for a multiuser MIMO system, where both the transmitter and the receiver are equipped with multiple antennas. In transmit beamforming multi-user multiplexing is performed using spatial diversity techniques so that a base station could serve multiple users in the same frequency band enabling a substantial saving in bandwidth

Let M and N be simply connected space forms, and U an open and connected subset of M. Further let n: U-*N be a horizontally homothetic harmonic morphism. In this paper we show that if n has totally geodesic fibres and integrable horizontal distribution, then the horizontal foliation of U is totally umbilic and isoparametric. This leads to a classification of such maps. We also show that horizontal

Obituary over American poet Mark Strand (1934 - 2014)

Abstract in Spanish Más atención se está dando a la necesidad de integrar la gestión del riesgo en el trabajo de desarrollo para poder reducir así la vulnerabilidad de los pobres que viven en áreas urbanas. Usando El Salvador como estudio de caso, este artículo analiza el proceso de integración en dos sectores de desarrollo: planificación urbana y vivienda social. El objetivo es identificar de qué
