Photonic Materials and Devices
Our recent advances in solid-state optoelectronic materials and devices will be reviewed. In the area of glass optics, fabrication of novel microstructured and multi-core fibers and their use in realizing single mode lasers will be summarized. In organic and plastic optics, photorefractive polymers for 3D display applications and nonlinear optical polymers for high speed modulators in RF photon...
متن کاملLower limb amputations in southern Finland 1984-1985.
To assess the current epidemiological situation concerning lower limb amputations in southern Finland the data on all amputations made in the catchment area of the Helsinki University Central Hospital were analysed for the period 1984-85. During the two-year period, 880 amputations of lower limbs were performed on 705 patients. The amputation rate was 32.5 per 100,000 inhabitants in 1984 and 28...

Epidemiological data on the periodontal health and oral hygiene practices of young individuals in Latin America are limited. This study was conducted in a sample of 355 first-year students randomly selected from 3,251 new students entering the largest university in Colombia. Participants received a periodontal examination and were interviewed about oral hygiene practices. Specifically, this stu...
متن کاملPhotonics Materials and Devices
Part 2 reviews the materials properties of photonic materials, such as structure (chemical bonds) and electrical conductivity (bands) in Group IV and III-V compound/alloy semiconductors. The correlation of the principal quantum number with optical, thermal and mechanical properties is examined. The definition of effective mass qualifies the energy-wavenumber dispersion relation for direct or in...
