Disposable materials enjoy annually steady growth in volume in the field of medical applications as surgical gowns, isolation gowns, and medical drapes which impede cross contamination from reusable protective apparel in a hospital. There are four levels of liquid barrier performance according to the American National Standard/Association for the Advancement of Medical Instrumentation (ANSI/AAM...

BACKGROUND Autoclaving, heat, irradiation or chemical detergents are used to disinfect autografts, allografts and biomaterials for tissue reconstruction. These methods are often associated with deterioration of mechanical, physical, and biological properties of the bone grafts and synthetic implants. High hydrostatic pressure has been proposed as a novel method preserving biomechanical and biol...

Inclusion body refolding processes are poised to play a major role in the production of recombinant proteins. Improving renaturation yields by minimizing aggregation and reducing chemical costs are key to the industrial implementation of these processes. Recent developments include solubilization methods that do not rely on high denaturant concentrations and the use of high hydrostatic pressure...

It is well known that the superconducting transition temperature (T(c)) of cuprate superconductors can be enhanced by varying certain structural and electronic parameters, such as the flatness of the CuO₂ planes or their doping level. We determine the uniaxial and hydrostatic pressure derivatives of T(c) in the structurally simple tetragonal compound HgBa₂CuO(4+δ) near optimal doping. Our resul...

the three-phase-lag model and green–naghdi theory without energy dissipation are employed to study the deformation of a two-temperature fiber-reinforced medium with an internal heat source that is moving with a constant speed under a hydrostatic initial stress and the gravity field.  the modulus of the elasticity is given as a linear function of the reference temperature. the exact expressions ...

in this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. in order that studies on different types of nanotubes be comparable, the chiral vectors of c and si-c nanotubes are selected as (7,7) and (5,5), respectively, so that    a similar volume of fluid is investigated ...

Buckling and post buckling of cylindrical shells under hydrostatic pressure is regarded as important issue in structure of submarines. These cylindrical shells have variable thickness due to construction process which effected by pressure of buckling and its destruction. In this paper, effects of changing thickness on buckling and destruction pressure under external hydrostatic pressure of a sh...
