Head-loss monitor

Practically all of the deposit/fouling monitors discussed so far are suitable for some degree of measurement or evaluation of biomass/biofilm activity. There are also other devices available, for example, a head-loss monitor. This device is simply a 6-ft-long stainless steel tube, through which cooling... 

Inform patient and family about possible toxic effects on the 8th cranial nerve monitor for loss of hearing, ringing or roaring in ears, or a feeling of fullness in head... 

A number of biochemical and clinical measurements are necessary for effective monitoring of patients receiving PN. Important clinical laboratory measurements include serum concentrations of electrolytes, hematologic indices, and biochemical markers for renal function, liver function, and nutrition status. Other important clinical measurements include vital signs, weight, total fluid intake and losses, and nutritional intakes. Weekly height/length and head... 

The facility is equipped with an on-line, timed, weight/volume diversion system that diverts the mainstream into the weighing and volumetric tanks while the content of a reserve tank is dumped into the upper holdup tank. In this way, the sudden loss of flow was compensated for and a constant pump head was maintained. The density of the medium can be monitored to within 1 % and was obtained by combining the flow speed and weight readout. A solid weight... 

These plots represent small time steps during the oscillatory motion the rheometer employs to monitor the sample. The above plot depicts the motion of the head of the rheometer as a black line, and illustrates the response of the sample with a grey dotted line. As a gel becomes more solid, the response of the material will move in phase with the head of tile rheometer, since the elastic modulus will be relatively stronger than the loss (viscous) modulus. During this time, both G and G" are growing as the crosslink density in the sample changes. The machine will report the data usually in the following manner.
