A model of indocyanine green (ICG) disposition from the moment of its injection in blood was developed. ICG disposition was characterized in five dogs deeply anesthetized with halothane, which decreased cardiac output and prolonged intravascular mixing. After ICG injection into the right atrium, femoral arterial blood samples were collected every 3 s for the 1st min and less frequently to 20 mi...

This paper develops a system model for electrification in a flow loop and investigates volume charge accumulation due to recirculatory flow between a charge source and several charge relaxation regions. Enhanced charge densities are predicted when the source is a filter and the residence time in the relaxation regions is small compared to the liquid dielectric relaxation time. Small scale flow ...

Intensive aquaculture releases large quantities of nutrients into aquatic bodies, which can lead to eutrophication. The objective of this study was the development of a biological recirculatory wastewater treatment system with a diazotrophic cyanobacterium, Aulosira fertilissima, and simultaneous production of valuable product in the form of poly-β-hydroxybutyrate (PHB). To investigate this pos...

The relationship between the changes in portal venous and hepatic arterial blood flows, in the liver is a much disputed question, it has tremendous significance in the practice of transplantation, and an explanation has been available since 1981, when Lautt published the so-called "adenosine washout theory". According to our earlier observations the decrease of portal pressure or flow consisten...

BACKGROUND There have been few reports of pharmacokinetic models that have been linked to models of the cardiovascular system. Such models could predict the cardiovascular effects of a drug under a variety of circumstances. Limiting factors may be the lack of a suitably simple cardiovascular model, the difficulty in managing extensive cardiovascular data sets, and the lack of physiologically ba...
