The importance of headwater streams
Even though headwater streams can constitute more than three quarters of the stream length in drainage basins, they have not been studied as much as other parts of the river system. Most headwater… Expand
The effect of rumen digesta inoculation on the time course of recovery from classical diet-induced milk fat depression in dairy cows.
Ten ruminally cannulated cows were used in a crossover design that investigated the effect of rumen digesta inoculation from non-milk fat-depressed cows on recovery from classical diet-induced milk… Expand
Biopolymer yields from activated sludge and their relation to the operation of treatment plant
SummaryProcedures for the extraction of biopolymers from activated sludge are compared with respect to yields. Statistical analyses show that the variations in polymer yield may be related to the… Expand
The production of polymer from activated sludge by ethanolic extraction and its relation to treatment plant operation
Nitrate, denitrification and sludge settlement in the activated sludge process
Abstract This paper examines the performance of one of the final settlement tanks at a large metropolitan sewage treatment works. The works has a history of high concentrations of suspended solids in… Expand
Short communication: Effect of a citrus extract in lactating dairy cows.
Dry matter intake is a main driver of energy balance in lactating dairy cows, and some plant extracts have been commercially fed to dairy cows to stimulate feed intake. Citrus extracts contain… Expand
The significance of ATP in the settlement of activated sludge
A laboratory-scale activated sludge plant treating simulated coke oven liquors was used to examine the settleability of the sludge in relation to its ATP concentration. On the basis of the data… Expand
