This paper studies a planning problem for heating water. Hereby, boilers (e.g. gas or electric boilers, heat pumps or microCHPs) are used to heat the water and store it for domestic demands. We consider a simple boiler which is either turned on or turned off and has a buffer of limited capacity. The energy needed to run the boiler has to be bought on a day-ahead market, so we are interested in ...

Water as a resource, basic amenity and universal solvent is shared by population. The physicochemical and biological quality study of Anekal Taluk has been taken up to evaluate its suitability for potable purposes. 1026 water samples were collected from bore well, hand pumps of 272 villages covering in Anekal Taluk. The quality of groundwater has been made through the analysis of pH, colour, el...

A 35-year-old man presented with recurrent lower extremity weakness associated with polyuria later progressing to generalised weakness with difficulty in breathing. The patient was hypotensive and dry, with normal thyroid and chest examination, weak lower extremity and carpopedal spasm. Workup revealed hypokalaemia, hyponatraemia, hypocalcaemia, hypomagnesaemia, hypochloraemia and hypophosphata...

Irrigation canals are large-scale systems, covering vast geographical areas, and consisting of many interconnected canal reaches that interact with control structures such as pumps and gates. The control of such irrigation canals is usually done in a manual way, in which a human operator travels along the irrigation canal to adjust the settings of the gates and pumps in order to obtain a desire...

Radiocarbon dating of ground water is used in combination with the primary measurements of classical hydrological and chemical analyses. Radiocarbon dating will produce the best results when it involves multiple measurements or sequential sampling. The most useful data come from these comparisons and not from absolute ages. In the case of multiple measurements, the apparent ages of the ground w...

The Clean Water Act of 1972 as amended in 1987 requires states to control the flow of pollution from storm water into local rivers. In most cases, this requirement is carried out through installation of an expensive system of pipes and pumps. The Tollgate Drainage District, Ingham County, Michigan, examined here, uses a more economical alternate approach: water from the district flows into an a...
