The Advanced Resistive Exercise Device (ARED) is an exercise device designed by NASA to allow for more intense workouts in zero gravity. The device was flown to the International Space Station during STS-126 [ 1 ] and installed in 2009 to replace its inefficient predecessor, the Interim Resistance Exercise Device. [ 2 ]
A burning apparatus consisting of two biconvex lens. A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.
Lower back pain is one of the largest healthcare expenditures in the United States, with the market for lumbar spine diagnostics and treatment estimated at $40 billion annually and overall costs reaching up to $134.5 billion. Aclarion’s NOCISCAN technology addresses this growing need by offering a noninvasive diagnostic alternative.
Administrative costs. About 25% of U.S. healthcare costs relate to administrative costs (e.g., billing and payment, as opposed to direct provision of services, supplies and medicine) versus 10-15% in other countries. For example, Duke University Hospital had 900 hospital beds but 1,300 billing clerks.
Vision rehabilitation (often called vision rehab) is a term for a medical rehabilitation to improve vision or low vision.In other words, it is the process of restoring functional ability and improving quality of life and independence in an individual who has lost visual function through illness or injury.
There still yet exists a low-cost device with high efficacy. [27] Additionally the precise mechanisms as to how sonophoresis works is currently yet to be discovered. Further research into the mechanisms, and the dominant mechanisms, can allow for better optimization of sonophoresis parameters, which will increase the efficacy of treatments.
Fixation disparity is a tendency of the eyes to drift in the direction of the heterophoria.While the heterophoria refers to a fusion-free vergence state, the fixation disparity refers to a small misalignment of the visual axes when both eyes are open in an observer with normal fusion and binocular vision.

A prism coupler is a prism designed to couple a substantial fraction of the power contained in a beam of light (e.g., a laser beam) into a thin film to be used as a waveguide without the need for precision polishing of the edge of the film, without the need for sub-micrometer alignment precision of the beam and the edge of the film, and without the need for matching the numerical aperture of ...
