In order to achieve high-level resilience against disasters, effective utilization of previous emergency management information is necessary. The goal of this project is to establish effective utilization of emergency management information and emergency response logs that are accumulated as a fundamental dataset to learn lessons for emergencies in the(More)
1. Stentor coeruleus exhibits negative phototaxis (due to phototactic orientation response) and step-up photophobic response (avoiding reaction) to visible light. 2. The effect of Ja-value ([K+]/[Ca2+]1/2) and calcium ion concentration of the surrounding medium on the photoresponses in Stentor were studied. 3. The both types of photoresponses in Stentor are(More)
Stentor coeruleus exhibits negative phototaxis and step-up photophobic response (avoiding reaction) to visible light (maximum at 610-620 nm in both responses). In the presence of deuterium oxide (D2O) the step-up photophobic response was markedly enhanced, whereas the phototactic orientation response was inhibited. The induction time for the step-up(More)
