Concentration ratios (CR(wo-media)) are used in most radioecological models to predict whole-body radionuclide activity concentrations in wildlife from those in environmental media. This simplistic approach amalgamates the various factors influencing transfer within a single generic value and, as a result, comparisons of model predictions with site-specific measurements can vary by orders of ma...

WO,/ZrO, catalysts prepared by different methods are distinct in their catalytic behaviour. In this work, WO,/ZrO, catalysts prepared by impregnating Zr(OH), and crystallized ZrO, and then calcining at selected temperatures were characterized by means of qualitative and quantitative Raman spectroscopy. The results showed that ZrO, in WO,/ZrO, obtained from crystallized ZrO, (referred to as WZ) ...

Unter den unterschiedlichen Verifikationsansätzen hat sich das Model Checking in den letzten Jahren immer stärker etabliert. So ist es beispielsweise möglich, Systeme mit realistischer Größe mit der Hilfe von Model Checkern zu verifizieren. Nicht nur im Hardewarebereich, wo bereits Systeme mit bis zu 10 Zuständen erfolgreich verifiziert wurden, sondern auch im Softwarebereich leistet Model Chec...

Methods for expressing a heteromeric taste receptor that responds to umami taste stimuli are provided. These methods comprise the co-expression of T1R1 and T1R3 nucleic acid sequences in a host cell that desirably also expresses a G protein that couples therewith, e.g., G.sub..alpha.15 and G.sub..alpha.16 or gustducin. In preferred embodiments, the host cells will be mammalian cells or Xenopus ...

Chemical sensors based on semiconducting metal oxide nanocrystals are of academic and practical significance in industrial processing and environment-related applications. Novel alcohol response sensors using two-dimensional WO(3) nanoplates as active elements have been investigated in this paper. Single-crystalline WO(3) nanoplates were synthesized through a topochemical approach on the basis ...

In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the ...

BACKGROUND The early detection of wearing-off in Parkinson disease (DEEP) observational study demonstrated that women with Parkinson's disease (PD) carry an increased risk (80.1%) for wearing-off (WO). This post hoc analysis of DEEP study evaluates gender differences on WO and associated phenomena. METHODS Patients on dopaminergic treatment for ≥ 1 year were included in this multicenter obser...
