Predicting Beef Fatty Acid Composition from Diet and Plasma Profiles Using Multivariate Models

Animals
The nutritional value of beef is highly influenced by its fatty acid composition. This study evaluated whether diet proximate analyses or plasma fatty acid profiles could predict the meat fatty acid composition in young beef cattle finished at pasture or

Observations of the Growth and Decay of Stall Cells during Stall and Surge in an Axial Compressor

International Journal of Rotating Machinery, 2017
This research investigated unsteady events such as stall inception, stall-cell development, and surge. Stall is characterized by a decrease in overall pressure rise and nonaxisymmetric throughflow.
