We propose here a large homogeneous calorimeter as the next generation neutrino detector for ν factories and/or conventional ν beams. The active media is chosen to be water for obvious economical reasons. The Čerenkov light produced in water is sufficient to have good energy resolution, and the pattern recognition is realized by a modular water tank structure. Monte Carlo simulations demonstrat...

Three evaporators are used to reduce the volume of waste in the waste tank farm at the Savannah River Site (SRS). Evaporators are crucial operation in the SRS waste processing and management system. Using the Aspen Custom Modeler (ACM) software package marketed by Aspen Technology, Inc., the evaporator dynamic flowsheet models have been constructed to simulate the behavior of the evaporator sy...

Thirty-five years ago, B.F. Skinner (1976) lamented a decreasing trend in the prevalence of cumulative records in the Journal of the Experimental Analysis of Behavior ( JEAB). The editorial began with the two memorable lines, ‘‘Evidently we have not long to wait for an issue of JEAB without a single cumulative record! I shall not miss the records so much as the kinds of experiments that could s...

Triboelektrostatická separácia minerálnej substancie zo slovenského uhlia V článku sú diskutované niektoré technické aspekty triboelektrostatickej separácie a výsledky aplikácie tohto postupu pri úprave troch typov uhlia, konkrétne energetického uhlia z Cígľa, Handlovej a Novák. Bolo zistené, že účinnosť separácie veľmi úzko závisí na druhu separovan uhlia. Prvé výsledky preukázali súvislosť me...

The potential of using Effective Microorganisms (EM) to purify waste water, including that of a sewage system, for recycling purposes was evaluated. The studies were extended to examine the potential of using treated sewage sludge as a fertilizer in crop production. Long term application of EM reduced the adverse characteristics of waste water. The quality of the treated water was high, which i...

Previous studies of the bacterial quality of roof-harvested rainwater have been confined to either detection of specific pathogens and faecal indicator organisms, or epidemiological studies of health effects associated with consumption of stored rainwater. As yet however, a general consensus on tank-water quality has not been reached. In this paper it is proposed that achieving reliable microbi...
