Protection against atherogenesis with the polymer drag-reducing agent Separan AP-30.
The inhibitory effect of Separan AP-30, an anionic polyacrylamide, on atherosclerotic plaque formation in aortas of rabbits on a high (2%) cholesterol diet was tested over a period extending from 37 to 170 days. Atherogenesis was quantified morphometrically by application of a computer-assisted image analysis of histologic cross sections of the aorta. The area of vessel wall-atheroma interface,...
متن کاملEffects of a drag-reducing polyelectrolyte of microscopic linear dimension (Separan AP-273) on rat hemodynamics.
Separan AP-273, a polydisperse, high molecular weight (10(5)-10(7) dalton range), anionic polyacrylamide, demonstrates polymer drag reduction (Toms effect) in the flows of several substances including blood. That is, under appropriate conditions, pipe flow can be increased markedly for a given pressure gradient, sometimes threefold or more, by nanomolar concentrations of linear macropolymers. T...
متن کاملAgent-Based Network Protection Against Malicious Code
This paper presents an agent-based approach to Network Intrusion Prevention on corporate networks, emphasizing the protection from fast-spreading mobile malicious code outbreaks (e.g. worms) and related threats. Agents are not only used as a system-integration platform, but we use modern agent approaches to trust modeling and distributed task allocation to efficiently detect and also counter th...
متن کاملAn improved diameter scaling correlation for turbulent flow of drag-reducing polymer solutions
The friction coefficient was measured for developed flow of drag-reducing polymer solutions in tubes of 2, 5, 10, 20 and 52 mm i.d. Our results were processed along with other authors' data in terms of different parameters in order to investigate the possibility of developing a simple empirical method for the prediction of the pipe diameter effect on friction. We found that the drag-reduction c...
متن کاملMeasurement of temperature profiles in turbulent pipe flow of polymer and surfactant drag-reducing solutions
A device was built to measure temperature profiles of turbulent pipe flows of various drag-reducing fluids. It is easy to use and reliable. We measured temperature profiles over a range of conditions leading to accurate measurements down to y+ 10, for tests carried over Reynolds numbers Re between 10 000 and 90 000. The effects of high heat fluxes and buoyancy, in particular, were quantified to...
