PURPOSE Comparison of the mechanical characteristics of meniscal repair fixation using horizontal sutures and six different sutures under submaximal cyclic and load to failure test conditions may aid physicians in selecting a suture type. METHODS A 2-cm long anteroposterior vertical longitudinal incision was created in six groups of bovine medial menisci. Lesions were repaired using a No. 2 s...

Strengthening muscles of the back may have various implications for improving functions of daily living, aiding in the transfer of power in throwing, and assist in injury prevention of the shoulder complex. While several versions of the pull-up exist, there is currently no literature comparing their differences. The purpose of this investigation was to compare the electromyographical activity o...

BACKGROUND Physical strength is associated with improved health outcomes in children. Heavier children tend to have lower functional strength and mobility. Physical activity can increase children's strength, but it is unknown how different types of electronic media use impact physical strength. METHODS Data from the NHANES National Youth Fitness Survey (NNYFS) from children ages 6-15 were ana...

As a vibration- free concrete, self- compacting concrete (SCC) can be easily used in the absence of consolidation, therefore; it is a good option for repairing and retrofitting concrete structures. The quality of repair layer is highly effective on a successful repair. Accordingly, in this study, factors affecting the quality of fiber-reinforced self-compacting concrete repair layer, including ...

In this study, a new medical bone screw was designed and manufactured by Ti6Al4VELI GR23 material and tested in accordance with the ATSM F 543-02 test procedure experimentally. This test is used to measure the axial tensile force required to fail or remove a bone screw from a defined material. Concurrently, 3-D Finite Element Analysis (FEA) models of these medical bone screws were developed to ...

The properties of the fiber/matrix interface in composites have an influence on their overall performance. Common methods for studying the interface are micromechanical tests that load a single fiber/matrix interface to failure. Two popular tests are the microbond test [1] and the single-fiber, pull-out test [2]. In a microbond test a droplet of matrix is sheared off the fiber by pulling the fi...
