PURPOSE New all-inside meniscal repair devices include those combining sutures with anchors and that allow for an "adjustable" repair. This study's purpose was to compare the failure strength of new meniscal repair devices with suture repairs. TYPE OF STUDY Experimental laboratory biomechanical study. METHODS A single repair was placed in a vertical longitudinal peripheral tear made in fres...

PURPOSE Pullout strength of screws is a parameter used to evaluate plate screw fixation strength. However, screw fixation strength may be more closely related to its ability to generate sufficient insertion because stable nonlocked plate-screw fracture fixation requires sufficient compression between plate and bone such that no motion occurs between the plate and bone under physiological loads....

Steel-fiber-reinforced concrete (SFRC) is a composite material made by randomly distributing short steel fibers in normal (NC). In this study, central pull-out tests of 32 specimens were performed to investigate the bond behavior between high-strength rebar and SFRC under influence fraction fiber volume (Vf = 0%, 0.5%, 1.0% 1.5%) temperature (T 20, 200, 400 600 °C). The results show that NC spe...

During the pullout maneuver, peregrine falcons were observed to adopt a succession of specific flight configurations that are thought offer an aerodynamic advantage over aerial prey. Analysis trajectory falcon in controlled environment shows it experiencing load factors up , and further predictions suggest this could be increased almost during high-speed pullout. This can attributed high maneuv...
