With the development of the graded-index technology, POFs have become leading candidates for home networking. Since the first Gl POF was reported in 1982, considerable efforts have been made to enhance Gl PDF s performance. For practical applications, many problems have to be overcome. In particular, fiber attenuation and thermal stability have been major issues. 

SCISEARCH contains bibliographic citations (links) to publications in science and technology. The database represents the electronic online version of the expanded Science Citation Index (SCI) and parts from the Current Contents of the Institute for Scientific Information (ISI). More than 5900 science and technical journals are included in the database with more than 20 million records (October, 2002). Searches can be performed on the bibliographic data, along with where, and how often, an author or publication is dted.

Diesel Fuel. Eederal diesel specifications were changed to specify a maximum of 0.05% sulfur and a minimum cetane index of 40 or a maximum aromatics content of 35 vol % for on-road diesel. Eor off-road diesel, higher sulfur is allowed. CARB specifications require 0.05% sulfur on or off road and 10% aromatics maximum or passage of a qualification test. Process technologies chosen to meet these specifications include hydrotreating, hydrocracking, and aromatics saturation.

Improvements in asthma treatment include the development of more effective, safer formulations of known dmgs. The aerosol adrninistration of P2-agonists or corticosteroids results in a decrease in side effects. Also, the use of reUable sustained release formulations has revolutionized the use of oral xanthines which have a very narrow therapeutic index (see Controlled release technology). For many individuals, asthma symptoms tend to worsen at night and the inhaled bronchodilatots do not usually last through an entire night s sleep (26,27). 

This technology also allows the control of refractive index profiles by doping. AH vapor-phase techniques use a vapor stream of volatile haUdes such as SiCl, GeCl, BCl, or POCl, and gases such as CI2 or O2. The reactants are oxidized and deposited onto a substrate to produce a soHd glass preform which is then drawn into a fiber. The variations of the technique differ in the way the reactants are oxidized (16).
