In this study, the microbiological quality of household tap water samples fed from rainwater tanks was assessed by monitoring the numbers of Escherichia coli bacteria and enterococci from 24 households in Southeast Queensland (SEQ), Australia. Quantitative PCR (qPCR) was also used for the quantitative detection of zoonotic pathogens in water samples from rainwater tanks and connected household ...

We use strictly ergodic dynamical systems to describe two methods for constructing short range interactions of classical statistical mechanics models with unique ground states and unusual properties of disorder; in particular, these ground states can be mixing under translations (and therefore have purely continuous spectrum), and can have positive entropy. Because of the uniqueness of the grou...

Thermophilic bacteria resembling Thermus aquaticus were isolated from hot water taken from domestic and commercial hot-water tanks. Cold water from the same locations never yielded thermophilic bacteria, suggesting that the bacteria were growing in the tanks. In contrast to the T. aquaticus isolates from hot springs, the present isolates were rarely pigmented. In general, the hotter sources mor...

Two forms of water service delivery in peri-urban settlements in the eThekwini municipal region are communal stand-pipes and household ground-tanks. Water from these sources requires storage prior to use. Previous studies have shown that water quality tends to deteriorate during storage. This study was conducted during the winter season and tested water from standpipe and ground-tank households...

Abstract Cosmic rays that strike the top of Earth’s atmosphere generate a shower secondary particles move toward surface with relativistic speeds. Water Cherenkov detectors (WCDs) on ground can detect charged muons, which are one many generated in shower, imaging technique. A large number these muons travel WCD tanks near speed light vacuum, faster than water, and so trigger isotropic radiation...

The city of Bekasi is experiencing rapid development so the demand for water increasing. To increase service coverage and meet drinking needs people City with a quality that meets Minister Health Regulation No. 492 2010, it planned to up rate capacity Teluk Buyung 4 WTP has 300 L/second raw source, namely West Tarum Secondary Channel. use design criteria from Equivalent evaluation, 3 literature...

Hickey and Wittenberg (Hickey and Wittenberg, 2004) study the “Two Tanks Problem”, a hybrid system described by Stursberg et al. (Stursberg et al., 1997). In this paper, we expand on the use of CLIP (Hickey, 2000) (a Constraint Logic Programming over Intervals and Functions language) to formally describe more complex systems. We add complexity in several forms. The simplest is to have a larger ...
