Background: Osteoporosis is a global age-related health problem in both male and female elderly, affecting the microstructure of bone. Although osteoporosis is normally associated with old age and estrogen deficiency, diabetes mellitus (DM), also con

A scanning tunneling microscope which uses a gallium arsenide tip has been successfully constructed. Atomic resolution is demonstrated by the imaging of the Si(111)‐7×7 surface in ultrahigh vacuum. Details of the tip preparation are given and the

The study sample was 6 rural health units and 405 attendants. Assessment of inputs was done through review of documents, charts, interviews, questionnaires and direct observation. Assessment of accuracy of the techniques was done by cross matching th

We incorporate the experimentally deduced flux line potential well structure into the flux creep model. Application of this approach to the resistive transition in Bi2Sr2CaCu2O8 epitaxial films explains the power law voltage‐current characteristics

We describe the voltage‐current characteristics of YBa2Cu3O7−δ epitaxial films within the flux creep model in a manner consistent with the resistive transition behavior. The magnitude of the activation energy, and its temperature and magnetic fi

We report a new design for an acoustically resonant spectrophone well suited for intracavity operation with widely tunable lasers. Operation with Brewster angle windows or in a windowless mode is possible, and high quality factors (560 and 509, respe

The photothermal deflection technique has been extended as a contactless method to investigate thermal transport in thin films. A theoretical model is developed which quantitatively describes the transport behavior, and is shown to be in excellent ag
