Longitudinal Changes in Adiposity After a Youth Sport‐Related Knee Injury: Informing Posttraumatic Osteoarthritis Prevention

Arthritis Care &Research, EarlyView.
Objective Youth who experience a sport‐related knee injury have elevated odds of becoming overweight or developing obesity in 3 to 10 years, compounding their risk for posttraumatic osteoarthritis (PTOA). To inform prevention strategies, this study compared patterns of adiposity change between youth with a sport‐related knee injury and uninjured youth ...

ALTERNATIVE LEATHER MANUFACTURING PROCESS - 1.PRE-TANNING WITH A REACTIVE OLIGOMERIC RESIN [PDF]

Annals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2018
This paper presents a non-conventional tanning technology, which uses a benzenesulfonate melamine-formaldehyde resin (BSMF) as pre-tanning agent. BSMF tanning alone can produce white leather, which generates chrome-free leather wastes. A BSMF pre-tanning

On the Effect of Creep on Local Lattice Orientation in Single‐Crystal Ni‐Based Superalloy Microstructures

Advanced Engineering Materials, EarlyView.
During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.
