TO THE EDITOR: I read the recent article by Peake et al. (4) entitled “Muscle damage and inflammation during recovery from exercise” with great interest. I would suggest adding more information about muscle damage, because in my opinion the authors talked about muscle damage minimally. The authors stated (4): “. . . Concentric muscle contractions do not cause exercise-induced muscle damage.” Bu...

Carbon fiber laminate composites, consisting of layers of polymer matrix reinforced with high strength carbon fibers, are increasingly employed for aerospace structures. They offer advantages for aerospace applications, e.g., good strength to weight ratio. However, impact during the operation and servicing of the aircraft can lead to barely visible and difficult to detect damage. Depending on t...

Silicon wafer thickness reduction without increasing the wafer strength leads to a high fracture rate during subsequent handling and processing steps. Cracking of solar cells has become one of the major sources of solar module failure and rejection. Hence, it is important to evaluate the mechanical strength of solar cells and factors influencing this. The purpose of this work is to understand t...
