Pre-failure indicators detected by Acoustic Emission: Alfas stone, cement-mortar and cement-paste specimens under 3-point bending

Fracture and Structural Integrity, 2018
Acoustic Emission (AE) is the technique most widely used nowadays for Structural Health Monitoring (SHM). Application of this technique for continuous SHM of restored elements of stone monuments is a challenging task.

Indicators of loss of consciousness in slaughter without stunning: a neuroanatomical reappraisal [PDF]

Frontiers in Veterinary Science
Minimizing animal suffering during slaughter depends on appropriate pre-slaughter handling, technique, and post-slaughter assessment. The post-slaughter phase must include rapid determination of loss of consciousness (LOC) using scientifically based ...
