The morphologies of biological materials, from body shapes to membranes within cells, are typically curvaceous and flexible, in contrast to the angular, facetted shapes of inorganic matter. An alternative dichotomy has it that biomolecules typically assemble into aperiodic structures in vivo, in contrast to inorganic crystals. This paper explores the evolution of our understanding of structures...

The primary claim of this paper is that understanding the stigma so commonly endured by chronic pain sufferers today in the USA and the UK is unlikely without proper appreciation of the history of pain. Ameliorating such stigma is an ethical imperative, and yet most approaches eschew even an attempt to trace connections between historical attitudes, practices and beliefs towards pain and the st...

AIM Occlusal errors during acryl processing affect the retention and stability of complete dentures. The aim of the present study was to assess the influence of a short curing technique on the number of occlusal contacts and the occlusal vertical dimension (OVD) of complete dentures. MATERIALS AND METHODS Complete dentures were prepared. The number of occlusal contacts was recorded in centric...

Experimental and commercial storage and ship ping tests of film-wrapped citrus fruit were conducted the past 5 seasons. Fruit wrapped in film lost less water than waxed fruit, creating the potential for better arrival condi tion of export fruit and for extended storage of fruit to pro long the domestic marketing season. Film wrapping may allow 1 to 2 month holding periods with little quality lo...
