Tritium Contents in Rain Water at Nagoya

Rain Attenuation at Terahertz

Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R. Measurements of Terahertz wave taken at 313 GHz (0.96 mm) were compared with our calculations. Result...

Tritium in [o]water, Its Identification and Method of Removal

18 years of conformation radiotherapy at Nagoya University Hospital.

Conformation radiotherapy is one of the best techniques for minimizing the radiation dose absorbed by the surrounding normal tissue while delivering a high dose to a cancerous target area. The cases of all patients who underwent external irradiation at Nagoya University Hospital from 1975 to 1992 were reviewed. A total of 5740 patients with 6179 lesions were irradiated during this time, and 379...

Simulation of Rain-Water Overland-Flow

Abstract. We are interested in simulating overland flow on agricultural fields during rainfall events. In this context, we definitely have to cope with dry/wet interfaces and water inflow on dry soil. The model considered is the Shallow Water system (or Saint-Venant equations) without infiltration. Moreover, the model has to be completed with friction terms. It is numerically solved by a finite...

Influence of acid rain upon water plumbosolvency.

The West of Scotland has had particular problems in the past associated with soft acidic water supplies and uptake of lead from domestic plumbing systems by such water. As a consequence of this, health problems related to overexposure to lead have been identified. The current debate on acidification of ground waters by acid rain is therefore particularly pertinent to this area. Studies have sho...
