New hydrolyzable polymer could lead to cheaper biomaterials

Can Optical Interconnects Lead to Cheaper High-Performance Multiprocessors?

A new paradigm for an all-to-all optical interconnect is presented. It could be part of an interconnection fabric between parallel processing elements and the first level of the cache in a computer system. Parallel processing has traditionally aspired to improve performance of such systems. An optical interconnect raises a new possibility: obtain both improved performance and significant cost r...

Errors in statistics could lead to misinterpretation.

In reviewing "The Use of Low-Load Prolonged Stretch Devices in Rehabilitation Programs in the Pacific Northwest" by Nuismer, Ekes, and Holm (AjOT, July/August 1997, pp. 538-543), I found several notable errors in the results. For example, when computing statistics for change in range of motion (ROM), a zero was mistakenly used instead of the reported -10 (Table 1, p. 541) for Subject 7. Table 1...

Sonochemical Synthesis of Novel Nano Flower Lead(II) Metal-organic Coordination Polymer: A New Precursor to Produce Nano-sized PbO

Metal-organic coordination polymers are a class of organic–inorganic materials consists of metal ions linked together through multi-dentate organic ligands, to form a polymeric chain. These materials have received a great deal of attention in a wide range of different areassuch as catalysis, sensing, luminescence, separation and storage used . The new nano flowerPb(II) 1Dmetal-organic chain {[P...

Fracture of Ceramic-Polymer Composite Biomaterials

Fracture toughness, strength, and elastic modulus of poly(methyl methacrylate) (PMMA)and poly(buty1 methacrylate) (PBMA)-impregnated alumina ceramics were measured as a function of polymer volume fraction, mean polymer particle size, and interfacial bonding between the polymer and ceramic. Fracture toughness was found to increase with increasing polymer volume fraction and decreasing polymer pa...
