The effect of amino acid supplementation on weight, body composition, muscle size, and muscle strength in amateur weightlifters
… an amino acid supplement on muscle size, muscle strength, body composition, and body weight. A blind protocol was followed in which eight of the participants were administered the amino acid supplement and seven received a placebo. Each subject was tested before and immediately after the ten week …

The fatigue-crack growth and fracture characteristics of a precipitation-hardened semiaustenitic stainless steel
Fatigue-crack propagation and residual static-strength data on PH15-7Mo (TH 1050) stainless steel are presented in this thesis. In addition, the capability of McEvily and Illg's crack-growth analysis and Kuhn and Figge's residual strength analysis to correlate the test data has been investigated. …
