Desirability of Oysters Treated by High Pressure Processing at Different Temperatures and Elevated Pressures
High Pressure Processing Different Temperatures
2016/6/2
Organoleptic changes in sterile triploid oysters (Crassostrea virginica) induced by high pressure processing (HPP) were investigated. Because pressure treatments evaluated were greater than current in...

Exploitation of Hertz抯 contact pressures in friction drives
contact pressures friction drive Hertz抯 pressures pitting friction force Mohr抯 circles
2014/2/26
The paper is intent on the applications of equations which describe the Hertz抯 surface pressures in friction drives. In the paper the reduced equations are derived, which are useful to the surface pre...
Effects of Weld Zone Properties on Burst Pressures and Failure Locations
Weld zone e ects DOT-39 refrigerant cylinders Nonlinear FEA analysis Burst pressures
2009/10/10
The effects of weld zone properties on the burst pressures and burst failure locations of DOT-39 nonre-allable refrigerant cylinders were examined using the nite element analysis (FEA) approach. In o...
Water Application Uniformity of a Subsurface Drip Irrigation System at Various Operating Pressures and Tape Lengths
Subsurface drip irrigation emitter discharge uniformity coefficient emitter performance
2009/1/9
Subsurface irrigation has been the focus of attention mainly because of its low evaporation rate and deep percolation losses. Uniformity of water applications and its stability, however, are still a m...
