Horizontal cryostat for fatigue testing Patent

Cryostat for use with horizontal fatigue testing machines at low temperature

Explosive bonded TZM-wire-reinforced C129Y columbium composites

Technique consists of positioning layers of TZM metal filaments between thin C129Y columbium sheets and joining multiple sheet stacks by single explosive joining operation. Metallurgical bonds are excellent, external heat is not required, process is relatively inexpensive, and resulting composites are considerably stronger than base alloy

Laminated sheet composites reinforced with modular filament sheet

Aluminum and magnesium composite sheet laminates reinforced with low density, high strength modular filament sheets are produced by diffusion bonding and explosive bonding. Both processes are accomplished in normal atmosphere and require no special tooling or cleaning other than wire brushing the metal surfaces just prior to laminating

Contextual barriers to mobile health technology in African countries: a perspective piece

On a global scale, healthcare practitioners are now beginning to move from traditional desktop-based computer technologies towards mobile computing environments[1]. Consequently, such environments have received immense attention from both academia and industry, in order to explore these promising opportunities, apparent limitations, and implications for both theory and practice[2]. The application of mobile IT within a medical context, referred to as mobile health or mHealth, has revolutionised the delivery of healthcare services as mobile technologies offer the potential of retrieving, modifying and entering patient-related data/information at the point-of-care. As a component of the larger health informatics domain mHealth may be referred as all portable computing devices (e.g. mobile phones, mobile clinical assistants and medical sensors) used in a healthcare context to support the delivery of healthcare services
