conclusions this study indicates that low-load rt results in greater accumulations in vl compared to high-load rt over the course of 8 weeks of training. results after adjusting for the pre-test scores, there was a significant difference between the two intervention groups on post-intervention total vl with a very large effect size (f (1, 15) = 16.598, p = .001, ηp2 = .525). there was a signifi...

INTRODUCTION After hip surgery, it is the orthopedist's decision to allow full weight bearing to prevent complications or to prescribe partial weight bearing for bone ingrowth or fracture consolidation. While most loading conditions in the hip joint during activities of daily living are known, it remains unclear how demanding physiotherapeutic exercises are. Recommendations for clinical rehabil...

In the design of land-based or offshore wind turbines for ultimate limit states, long-term loads associated with return periods on the order of the service life (20 years, usually) must be estimated. This requires statistical extrapolation from turbine load data that may be obtained by simulation or by field tests. The present study illustrates such extrapolation that uses field data from the B...

Activities with high spinal loads should be avoided by patients with back problems. Awareness about these activities and knowledge of the associated loads are important for the proper design and pre-clinical testing of spinal implants. The loads on an instrumented vertebral body replacement have been telemetrically measured for approximately 1000 combinations of activities and parameters in 5 p...

Title of dissertation: MODELS FOR RAPID ASSESSMENT OF LEADLESS COMPONENT FAILURES DURING PRINTED WIRING BOARD BENDING Nathan John Blattau, Doctor of Philosophy, 2004 Dissertation directed by: Professor Donald Barker Department of Mechanical Engineering The proliferation of leadless ceramic chip components has caused their failure to become a critical issue in the electronics industry. The major...

OBJECTIVE To quantify the dynamic loads and intervertebral motions throughout the cervical spine during simulated rear impacts. METHODS Using a biofidelic whole cervical spine model with muscle force replication and surrogate head and bench-top mini-sled, impacts were simulated at 3.5, 5, 6.5, and 8 g horizontal accelerations of the T1 vertebra. Inverse dynamics was used to calculate the dyna...

Title of Dissertation: DEVELOPMENT OF MACH SCALE ROTORS WITH COMPOSITE TAILORED COUPLINGS FOR VIBRATION REDUCTION Jinsong Bao, Doctor of Philosophy, 2004 Dissertation directed by: Professor Inderjit Chopra Department of Aerospace Engineering The use of composite tailored couplings in rotor blades to reduce vibratory hub loads was studied through design, structural and aeroelastic analysis, fabr...

Bone fractures occur frequently at mid-shaft femoral site during frontal and offset automotive crashes. Because these injuries are expensive, it is crucial to understand the injury mechanisms if this injury is to be prevented. The experimental investigation of femoral shaft tolerance under loading corresponding to real world accidents requires a challenging test setup that allows applying exter...

Studies of limb bone loading during terrestrial locomotion have focused primarily on birds and mammals. However, data from a broader functional and phylogenetic range of species are critical for understanding the evolution of limb bone function and design. Turtles are an interesting lineage in this context. Although their slow walking speeds and robust limb bones might lead to low locomotor for...
