In the last two decades, Lithium-ion (Li-ion) batteries have become an inherent part of dayto-day life thanks to their widespread use in many consumer products and electric vehicles. While these batteries possess great advantages, they also carry an inherent safety liability: In case of a crash event, short-circuit failure of the battery may develop, leading to thermal runaway, fires and even e...

The weakly cemented sandstone is widely distributed in the Western Mining Area, which mainly formed by mineral grains and minerals through compaction cementation. To study influence of grain size on mechanical properties acoustic emission (AE) characteristics sandstone, uniaxial compression Brazilian splitting AE tests were carried out four specimens with different sizes. physical properties, b...

During locomotion, the anterior cortex of the equine radius is loaded predominantly in tension, the posterior predominantly in compression. The anterior cortex is relatively strong in tension, the posterior in compression. We investigated the pattern of failure of specimens from the two cortices using laser scanning confocal microscopy. All specimens were loaded in four-point bending to increas...

Please cite this article in press as: Xiong J et al. M doi:10.1016/j.matdes.2010.08.016 A new type of lightweight sandwich panels consisting of vertically aligned hollow Al–Si alloy tubes as core construction and carbon fiber composite face sheets was designed. The hollow Al–Si alloy tubes were fabricated using precision casting and were bonded to the face sheets using an epoxy adhesive. The ou...

The load-displacement behavior of 35 fresh adult cervical spine motion segments was measured in compression, shear, flexion, extension, lateral bending and axial torsion tests. Motion segments were tested both intact and with posterior elements removed. Applied forces ranged to 73.6 N in compression and to 39 N in shear, while applied moments ranged to 2.16 Nm. For each mode of loading, princip...

Study Design Technical report. Objective Multilevel osteoporotic vertebral compression fractures may lead to considerable thoracic deformity and sagittal imbalance, which may necessitate surgical intervention. Correction of advanced thoracic kyphosis in patients with severe osteoporosis remains challenging, with a high rate of failure. This study describes a surgical technique of staged vertebr...

Precursor T lymphoblastic lymphoma (T-LBL) often manifests as a mediastinal mass sometimes compressing vital structures like vessels or large airways. This case was a 40-year-old male who developed T-LBL presenting as respiratory failure caused by mediastinal T-LBL. He presented with persistent life threatening hypoxia despite tracheal intubation. We successfully managed this respiratory failur...

OBJECTIVE To investigate the biomechanical properties of the percutaneous compression plating system for intertrochanteric hip fractures. DESIGN A biomechanical laboratory investigation on human cadaveric upper femora was conducted. SETTING Biomechanical laboratory. PATIENTS Sixteen femora from cadavers of patients aged 60 to 85 years. INTERVENTION An intertrochanteric fracture was perf...

Structural bolts have been widely used in prefabricated construction to connect one steel column another due their and structural benefits. In recent years, innovative column-to-column (PCC) connections using normal developed simplify the process of concrete-filled tubular (CFST) columns transfer upper load bottom through bolt-coupler connection. The PCC connection are under compression. Theref...

Compression techniques seem to be the primary factor in determining the success of both plating and nailing techniques for the management of acute fractures and for delayed and nonunion management of these fractures. An intramedullary nail that can provide continual compression (like a plate) and mechanical manipulation of the callous throughout the course of treatment is an ideal device that p...
