Numerical Simulation Study on Effect of Freezing Temperature on Quality of Fresh Frozen Plasma

open access: yesZhileng xuebao, 2018
When the central temperature of the plasma bag reaches ?30 ℃ the freezing process is finished. The cooling rate and the temperature uniformity of the plasma bag during freezing are two key factors for determining the freezing quality of plasma.

Common Warm Dust Temperatures Around Main-sequence Stars [PDF]

open access: yes, 2011
We compare the properties of warm dust emission from a sample of main-sequence A-type stars (B8-A7) to those of dust around solar-type stars (F5-K0) with similar Spitzer Space Telescope Infrared Spectrograph/MIPS data and similar ages.

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

open access: yesAdvanced Engineering Materials, EarlyView.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).
