Livelihoods in the Dry Zone of Sri Lanka have traditionally revolved around paddy cultivation under village tanks. In recent times water-use strategies have responded to a range of demographic and environmental pressures. This has implications for the sustainable management of natural resources, especially living aquatic organisms. The impacts of such change need to be understood at the level o...

The novel idea of water Cherenkov calorimeter made of water tanks as the next generation neutrino detector for ν factories and ν beams is investigated. A water tank prototype with a dimension of 1×1×13m is constructed, its performance is studied and compared with a GEANT4 based Monte Carlo simulation. By using measured parameters of the water tank, including the light collection efficiency, att...

Sloshing waves in moving tanks have been studied numerically, theoretically and experimentally in the past several decades. Most reported studies have been for tanks excited by forcing motion in a limited number of directions and with fixed excitation frequencies throughout the forcing. In the present study, a time-independent finite difference method is used to simulate fluid sloshing in the t...

OBJECTIVE Identify a source of contamination to explain the increase in the number of cases of S. Paratyphi B var. Java infection. METHOD A descriptive study was conducted to gather more information about cases and potential risk factors for infection. Between January 2000 and June 2003, we identified and interviewed by questionnaire 53 people with S. Paratyphi B infection. Due to the suspect...

on the Columbia River plateau, a semiarid region in south-central Washington (Fig. 1), the Hanford Site At the Hanford Site, highly radioactive and chemically aggressive served as a plutonium production facility for nuclear waste fluids have leaked from underground storage tanks into the vadose zone. This paper addresses hydrogeological issues at the weapons from 1944 to the end of the Cold War...
