Consolidation, Pre- and Post-Peak Shearing Responses from Internally Instrumented Biaxial Compression Device
An internally instrumented, servo-controlled biaxial compression device is described for evaluating shear band formation in soils. Internally measured vertical and lateral soil displacements as well as lateral deformations of a very low friction bottom sled allow one to observe the progressive development of shear bands in a specimen. Anisotropically consolidated specimens of relatively ...

Tips and Precautions for Using Oxygen Concentrator
Using an oxygen concentrator to breathe additional oxygen is safe and life-sustaining. However, just like with any other form of gadget, it’s vital to know a few tricks to get the most out of it. A common misunderstanding is that portable oxygen concentrators are the same as compressed oxygen or oxygen tanks, which are both methods of supplying more oxygen. As a result of the oxygen ...

Nitinol Applications
Although many nitinol applications are not well-known to the public, some applications are quite routine and familiar. The spectacle frame made of Nitinol severely deformed and then returned to normal. Similarly, a few years ago, when mobile phone antennas were made of Nitinol, they could bend without breaking or permanently bending. Another superelastic application of Nitinol is for orthodontic ...

Finite Element Study of a Lumbar Intervertebral Disc Nucleus Replacement Device
Nucleus replacement technologies are a minimally invasive alternative to spinal fusion and total disc replacement that have the potential to reduce pain and restore motion for patients with degenerative disc disease. Finite element modeling can be used to determine the biomechanics associated with nucleus replacement technologies. The current study focuses on a new nucleus replacement device ...
