Emission Spectroscopic Boundary Layer Investigation during Ablative Material Testing in Plasmatron.

Ablative Thermal Protection Systems (TPS) allowed the first humans to safely return to Earth from the moon and are still considered as the only solution for future high-speed reentry missions. But despite the advancements made since Apollo, heat flux prediction remains an imperfect science and engineers resort to safety factors to determine the TPS thickness. This goes at the expense of embarked payload, hampering, for example, sample return missions.

Use of a Central Catheter Maintenance Bundle in Long-Term Acute Care Hospitals.

Objective: Evidence-based guidelines have resulted in decreases in bloodstream infections associated with central catheters (CLABSIs) in hospital intensive care units. However, relatively little is known about CLABSI incidence and prevention in long-term acute care hospitals (LTACHs).

Methods: A central catheter maintenance bundle was implemented in 30 LTACHs, and compliance with the bundle was tracked for 6 months.
