And the "three-factor quadratic regression orthogonal rotary method" was adopted to study mixing performance of the mixer,after the machine had been designed and trial-produced. It was showed that the optimum technological parameters for mixing time, block coefficient and rotary speed of the paddle shaft were 180 s, 0.75 and 56 r/min, respectively. At the same time, the remains in the bin was little (0.015%). The effe...

Methods: The authors conducted medical record reviews and telephone interviews of 106 consecutive patients with ACL reconstruction using quadrupled semitendinosus-gracilis autograft from 2004 to 2006. Data included anthropometric measurements (height, mass, gender, and age at the time of surgery). Hamstring diameter was obtained using cylindrical sizers in 0.5-mm increments and recorded in the patient's surgical record. Correlation coefficients and stepwise, multiple linear regression were used to determine the relationship between the outcome variable and the predictor variables (age, gender, height, mass, and BMI). Independent sample t tests were used to compare hamstring graft diameter between genders.
