Sealing effects of cross-linked gelatin

Journal of Biomaterials Applications, 2012
Surgical sealants form gel when applied to tissues. Currently, fibrin sealant has been successfully used in many surgical fields, but it has several disadvantages, including possible virus transmission, low adhesive strength, and high cost. In this study, gelatin and glutaraldehyde (GA) solutions were chosen to demonstrate the effectiveness of cross ...

Effect of surface roughness of mechanical seals under blood sealing

Lubrication Science, 2010
AbstractA miniature mechanical seal with cooling water circulating system has been developed as a shaft seal for rotary blood pumps. The present paper describes the establishment of the experimental methods under blood sealing and the estimation of the effect of the surface roughness on the shaft seal problems, especially in the increase of the ...

Comparison of Rim Sealing Effectiveness in Different Geometrical Configurations

Heat Transfer
The flow field developing inside the stator-rotor cavities of gas turbines is characterized by a complex unsteady behaviour which still requires expensive and time consuming CFD simulations to be accurately modelled.

Cost-Effectiveness of Pit and Fissure Sealing at Schools for Caries Prevention in China: A Markov Modeling Analysis

Caries Research, 2023
The World Health Organization states that the application of pit and fissure sealants (PFSs) is an effective way to prevent dental caries. Estimates of potential health and economic impacts of PFS upon school-age children provide crucial evidence to ...

Effects of Purge Flow Configuration on Sealing Effectiveness in a Rotor–Stator Cavity

Journal of Engineering For Gas Turbines and Power, 2017
Secondary air is bled from the compressor in a gas turbine engine to cool turbine components and seal the cavities between stages. Unsealed cavities can lead to hot gas ingestion, which can degrade critical components or, in extreme cases, can be ...
