In this study, the evaluation of audiovisual interaction regarding to the sounds and colours of trains was investigated. Different pictures of trains were modified in their colors and presented on a liquid crystal screen in a sound proof room with the appropriate sound of the train. The subjects judged the loudness of the sound-picture stimuli with the(More)
Snake venoms are responsible for two reported human deaths as determined by the double diffusion method. Double diffusion is a simple, rapid, and reliable method, but it is rather qualitative and requires a rather large quantity of sample. In order to evaluate venom concentration more quantitatively, the more sensitive ELISA (enzyme linked immunosorbent(More)
The doping effects on the proton incorporation and protonic conductivity of perovskite-type SrZrO3 were investigated using the density functional theory (DFT) with the generalized gradient approximation (GGA). The optimized geometries, formation energies of hydrogen defect and activation energies for hydrogen diffusion in SrZrO3 doped with Al, Sc, Ga, Y,(More)
This paper describes the detection limit for 23 drugs and chemicals in the blood by means of a screening method that uses a gas chromatographic system equipped with a wide-bore capillary column and a nitrogen phosphorus detector. The detection limit by this method was determined as being 1 mm of peak height at the detector's range of 100 and 8 of(More)
A screening method for detecting volatile hydrocarbons in blood has been developed using gas chromatography/mass spectrometry with a wide-bore capillary column and a headspace method. Toluene-d8 and indan were used as the internal standards for quantitative analysis. Hydrocarbons with retention indices from 600 to 1200 were simultaneously and quantitatively(More)
A new approach to investigate the circumstances relating to carbon monoxide intoxication by analysing volatile hydrocarbons in the blood of cadavers is reported. Headspace gas chromatography/mass spectrometry was used to demonstrate the hydrocarbons. The results can be characterized into four categories depending on the compounds detected. In construction(More)
