Devolatilization- and surface renewal study with a LIST co-rotating processor

In the devolatilization step of polymn. processes, extruders are widely used for surface renewal. The LIST co-rotating processor (CRP) studied in the present paper, shows high performance for devolatilization processes. A sepn. model is correlated with exp ...

Residual strain effects on the stress field in a thick wall finite element model of the human carotid bifurcation

Nikolaos Stergiopoulos, Jean-Jacques Meister

A three-dimensional finite element model of the carotid artery bifurcation was constructed in order to determine the stress field and assess the modification of the stress field when residual strain is taken into account. Residual strain in the carotid bif ...

A new photopolymerizable blood vessel glue that seals human vessel anastomoses without augmenting thrombogenicity

Jeffrey Alan Hubbell

A new nonbiologic photopolymerizable glue, polyethyleneglycol 400 diacrylate, was studied with respect to its mechanical and biochemical interaction with human blood vessels. Using the human placental artery model, we tested the ability of polyethyleneglyc ...

Rapid Cross-Field Ion-Transport in a Plasma with Sheared Parallel-Flow

Ambrogio Fasoli

Test-particle measurements of plasma cross-field ion transport show a dramatic change associated with the presence of sheared plasma flow parallel to a fixed magnetic field. Experimental conditions for enhanced transport are consistent with a simple model ...

The use of laser-light scattering and controlled shear in platelet aggregometry

Jeffrey Alan Hubbell

Laser-light scattering was used to observe and quantify the dynamics of human blood platelet aggregation in platelet-rich plasma (PRP). Aggregation was performed in a controlled shear environment by placing the PRP in the annular space between a rotating c ...

The short-term blood biocompatibility of poly(hydroxyethyl methacrylate-co-methyl methacrylate) in an in vitro flow system measured by digital videomicroscopy

Jeffrey Alan Hubbell

An in vitro flow system for short-term blood biocompatibility testing of solution-castable polymeric biomaterials was developed. This system was relatively free of artefacts resulting from blood contact with materials other than the test material itself. I ...

Shear deactivation of enzymes in membrane reactors

Albert Renken

The technique of ultrafiltration can be applied for the recovery of biocatalysts in discontinuous as well as continuous reaction processes. The operation of ultrafiltration membrane reactors requires establishment of a certain shear rate along the membrane ...
