Title of Document: THE HYDROLOGIC AND WATER QUALITY PERFORMANCE OF THE SLIGO-DENNIS BIORETENTION CELL. Jennifer M. Olszewski, Master of Science, 2010 Directed By: Professor Allen P. Davis Civil and Environmental Engineering Bioretention cells have been found to improve the hydrologic and water quality performance of impervious areas such as parking lots. The current study recorded hydrologic da...

Silica aerogels display exceptional properties and great application potential, with a mature market in thermal insulation. Both supercritical drying (SCD) ambient pressure (APD) routes are implemented industrially. Herein, how aging silica content affect the mechanical properties, these turn determine shrinkage, spring back, density during APD systematically investigated. The densities U-shape...

Most glenoid implants rely on large centrally located fixation features to avoid perforation of the glenoid vault in its peripheral regions. Upon revision of such components there may not be enough bone left for the reinsertion of an anatomical prosthesis. Multiple press-fit small pegs would allow for less bone resection and strong anchoring in the stiffer and denser peripheral subchondral bone...

"The most important function of a bed is to support your body, especially the spine, so that your muscles can relax while you rest. Ideally, your spine should keep its natural curve when you sleep on your back, and stay straight when you lie on your side. A good mattress will mould itself to the shape of your body: it should let your shoulders and hips sink into it, but then spring back to give...

Commercially available prosthetic hands are simple grippers with one or two degrees of freedom; these pinch type devices have two rigid fingers in opposition to a rigid thumb. This paper focuses on an innovative approach for the design of a myoelectric prosthetic hand. The new prosthesis features underactuated mechanisms in order to achieve a natural grasping behavior and a good distribution of...

background: different environmental conditions, such as high temperature or exposure to some chemical agents, may affect the force decay of different methods of space closure during orthodontic treatment. the aim of this in vitro study was to evaluate the force decay pattern in the presence of tea as a popular drink in some parts of the world and two mouthwashes that are usually prescribed by t...
