Many houses suffer from a delay in hot water arrival, after opening the tap, due to length of pipe work boiler or thermal store. Measurements three properties showed delays up 46 s. A recirculation system could maintain at suitable temperature and for 15 m is expected use 30 W less electrical power than local store delivery point. Time-steady eigenvector solutions linked equations allow optimis...

Biofilm formation is one of the major problems of recirculating cooling water systems which detriments the life of equipment, through biocorrosion or microbiologically influenced corrosion (MIC). Sulfate reducing bacteria (SRB) are considered to be the major bacterial group involved in MIC. In the present study, SRB cultures are isolated from aeration basin inlet water sample of cooling water s...

Over the past hundred years, agriculture productivity in the United States has reached record levels through mechanization, intensification, and automation. The short history of aquaculture has also seen a similar trend of increasing production levels in both open pond systems and indoors intensive recirculation systems. Improved monitoring and control of these production systems will yield a r...

BACKGROUND Lowering water heater temperature set points and using less drinking water are common approaches to conserving water and energy; yet, there are discrepancies in past literature regarding the effects of water heater temperature and water use patterns on the occurrence of opportunistic pathogens, in particular Legionella pneumophila. Our objective was to conduct a controlled, replicate...

Purpose: We herein describe the clinical course of a consecutive series of fulminant hepatic failure patients treated with molecular adsorbent recirculating system, a cell-free albumin dialysis technique. From November 2000 to September 2002, 7 adult patients age 22-61 (median 41), one male (14.2%), and 6 females (85.7%), affected by fulminant hepatic failure, underwent 7 courses (1 to 5 sessio...
