Laboratory experiments on saline ice are often performed cold, isothermal and dry specimens out of convenience versus working with warm or floating in water. The laboratory conditions, thus, usually involve non-natural conditions. This study compares cyclic loading covering the main range ocean wave periods both dry, warm, specimens. Results indicate that −2.5°C have higher moduli than an avera...

No validated, generally accepted data set on the mechanical properties of brain tissue exists, not even for small strains. Most of the experimental and methodological issues have previously been addressed for linear shear loading. The objective of this work was to obtain a consistent data set for the mechanical response of brain tissue to either compression or shear. Results for these two defor...

BACKGROUND Intermittent pneumatic compression (IPC) has been shown, by duplex, to increase popliteal artery flow in normal legs and in legs with superficial femoral artery occlusion. The objective of this study was to see if IPC improves distal circulation in legs with severe infra-popliteal disease. PATIENTS AND METHODS Sixteen chronically ischemic legs with arteriographically demonstrated c...

many studies have considered the effects of suspension properties on the dewatering process but fewhave focused on ore properties. thus, the present work studied the effects of ore properties (density,particle size, mineralogy) on the dewatering process based on lab and pilot experiments. a hydrocyclonewas used to prepare the required samples for the experiments. to study the effects of mineral...

spinal epidural haemorrhage may present as back pain associated with radicular symptoms and can be a catastrophic clinical scenario with progression to paraplegia or even sudden death. being a rare entity, it needs a high index ofclinical suspicion to diagnose it. fractures have been documented as a cause of hematorrachis but such hematomas only extend to one or two vertebral segments. large ep...

a 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. plain x-ray revealed a large cauliflower shaped exophytic mass at the level of t8, t9 and t10 vertebrae. computed tomography (ct) and magnetic resonance imaging (mri) showed an abnormal bony mass arising from the posterior arch of t9 with protrusion...

Recent distributed computing applications are developed using different platforms working on different Operating Systems and these applications are running on heterogeneous hardware. SOAP protocol is mainly used for communicating among heterogeneous processes developed in platforms like .Net, Java, Android and so on. SOAP messages are basically XML documents and thus because of use of XML messa...

Liquid nitrogen was subjected to multiple shock compression to examine its response to pressures (15-40 GPa) and temperatures (1800-4000 K) previously unexplored in static and shock compression studies. Raman spectroscopy measurements were used to characterize the molecular bond response and to determine temperatures in the peak state. By extending our analysis to include other Raman spectrosco...

Mechanical behavior of articular cartilage was characterized in unconfined compression to delineate regimes of linear and nonlinear behavior, to investigate the ability of a fibril-reinforced biphasic model to describe measurements, and to test the prediction of biphasic and poroelastic models that tissue dimensions alter tissue stiffness through a specific scaling law for time and frequency. D...
