We studied on the feasibility of focused ultrasound for tactile feeling display. Our experiments showed that focused ultrasound at 1 MHz and 5 MHz effected our somatic sensation both by its radiation pressure and by direct stimulation to the nerve structures. The radiation pressure force generated by our apparatus was 0.23 gf/cm per 1-watt power consumption and evoked tactile feeling stably, wh...

Most people are aware that regular alcohol drinkers can become tolerant to the effects of alcohol. Tolerance can lessen the outward manifestations of intoxication, and this poses challenges for the drinker and other observers, including law enforcement officers. On the basis of a National Institutes of Health-funded longitudinal study examining a cohort of convicted alcohol-impaired drivers, th...

Two types of Triton X-100 extracted model of Paramecium caudatum were prepared and effects of the ionic compositions of the reactivating medium on the swimming behaviour of the extracted models were examined. Type I, prepared by the method of Naitoh and Keneko, did not change swimming direction depending on the concentrations of Mg2+ and K+ in the reactivating medium. Type II, prepared by a dif...
