The computed tomographic (CT) appearance of unfused ossicles in the lumbar spine has had little attention. Unfused ossicles result from accessory ossification centers near the tip of the vertebral processes. Their main importance lies in distinguishing them from fractures. The CT appearance of unfused ossicles in the lumbar spine was correlated with that of the corresponding surface anatomy fro...

The mechanical response of magnesium alloy AZ31B is addressed thanks to four-point bending tests. These alloys are known have an asymmetrical behavior in tension-compression. test is, therefore, a good candidate analyze this effect because it combines the two solicitations. Digital image correlation used measure evolution strain fields during test. Measurements shift neutral line (zero strain) ...

This paper addresses the narrow applicable fracture toughness range of master curve method (ASTM-E1921) by expanding scaling process to include effect constraint loss in miniaturized specimens. To facilitate acquisition and scalability reliable data from one specimen size another apply Master-Curve with confidence when using small specimens, difference structure crack tip stress field between l...

Intravascular large B-cell lymphoma (IVLBCL) is a rare and aggressive subtype of systemic extranodal non-Hodgkin diffuse large B-cell lymphoma (DLBCL). We report a rare case of IVLBCL who showed diffuse 18F-fluorodeoxyglucose (FDG) uptake in the lung in FDG-positron emission tomography/computed tomography (PET/CT) without respiratory symptoms or chest CT abnormalities. Serum biochemical studies...

Induction of hypertrophy and inhibition of apoptosis may be important mechanisms contributing to increased airway smooth muscle (ASM) mass in asthma. Data from our laboratory indicates that cardiotrophin-1 (CT-1) induces hypertrophy and inhibits apoptosis in isolated human airway smooth muscle cells. To determine whether these novel effects of CT-1 also occur in the airway tissue milieu and to ...

The objective of this study is to develop a numerical tool using the commercial software, Abaqus and Python, predict fatigue crack front shape while taking into account influence plasticity induced closure on propagation in three Dimensional (3D) structures. In aim, 3D model compact tension specimen made out stainless steel 304L, subjected constant loading scheme, proposed. considered be driven...

In this paper, we present the dynamic response of commercially pure copper subjected to combined tension-torsion loads representative real case impact scenarios. Experiments were conducted both quasi statically, at a strain rate equal 10?3 s?1, and dynamically rates in region between 500 s?1 1000 s?1. All high experiments using novel Split Hopkinson Tension-Torsion Bar instrumented with high-sp...
