The potential of an electronic nose consisting of a hybrid gas sensor array system has been examined for species discrimination and strain identification of dermatophytes which are causative pathogens for human and animal infection. Temporal volatile production patterns have been studied at a species level for a Microsporum species, two Trichophyton species and at a strain level for the two Tri...

The phenomenon of evaporation of volatile metal bath components can be observed in numerous process of both extractive metallurgy and refi ning. In some of them, this phenomenon can be considered positive, in others, however, to the contrary. In order to intensify the evaporation process or to restrain it, one must necessarily know the factors determining its rate. The most important of those f...

In this paper we propose a new method for volatile time series forecasting using Independent Component Analysis (ICA) algorithms and SavitzkyGolay filtering as preprocessing tools. The preprocessed data will be introduce in a based radial basis functions (RBF) Artificial Neural Network (ANN) and the prediction result will be compared with the one we get without these preprocessing tools or the ...

An acute confusional state was observed to follow heavy exposure to polyurethane gloss paint fumes in a previously healthy 60 year old man. This state remitted over a 3-day period, but was followed by transient bone marrow suppression and evidence of liver cell damage. The corroborated absence of other toxins and the temporal association of exposure to paint fumes suggest that a volatile paint ...

In this paper we summarize various possible techniques such as Crossover Prediction Model or the classical Principal Component Analysis (PCA) tool to include exogenous data. Furthermore we propose a new method for volatile time series forecasting using Independent Component Analysis (ICA) algorithms and Savitzky-Golay filtering as preprocessing tools. The preprocessed data will be introduce in ...

Introduction and Background: The Mars Science Laboratory (MSL) CheMin instrument on the Curiosity rover is a transmission X-ray diffractometer (Co-K radiation source and a ~5 to ~52 2 range) where the analyzed powder samples are constrained to have discrete particle diameters <150 μm by a sieve [1]. To date, diffraction patterns have been obtained for one basaltic soil (Rocknest (RN)) and f...

Since volatile anesthetics inhibited high voltage-gated calcium channels and G-protein-coupled M(1) muscarinic signaling, their effects upon M(1) receptor-induced modulation of L-type (alpha1C) calcium channel was investigated. Voltage-clamped Ba(2+) currents (I(Ba)) were measured in Xenopus oocytes coexpressed with L-type channels and M(1) muscarinic receptors. M(1) receptor agonist, acetyl-be...

A mathematical model for the simulation of spherical bubble dynamics in binary alkane mixtures is presented. Detailed heat and mass transfer phase transition are resolved, air absorption desorption considered. As example mixtures, high-volatile heptane low-volatile dodecane investigated. The component shows a convective counter-intuitive transport opposite to diffusion flux. staggered flux asso...

The volatile composition of veal has yet to be reported and is one of the important factors determining meat character and quality. To identify the most important aroma compounds in veal from Holstein bull calves fed one of three diets, samples were subjected to solid-phase microextraction (SPME) combined with gas chromatography-quadrupole mass spectrometry (GC-MS). Most of the important odoran...

Volatile profiles yielded from gas chromatography-mass spectrometry (GC-MS) analysis provide abundant information not only for metabolism-related research, but also for chemotaxonomy. To study the chemotaxonomy of Mangshanyegan, its volatile profiles of fruit and leaf and those of 29 other genotypes of Citrus, Poncirus, and Fortunella were subjected to phylogenetic analyses. Results showed that...
