pressurized storm sewer simulation: model enhancement. final rept jul 89-aug 90

a modified pressurized flow simulation model, pfsm, was developed and attached to the federal highway administration, fhwa, pool funded pfp-hydra package. four hydrograph options are available for simulating inflow to a sewer system under surcharge or pressurized conditions. several key parameters, such as time-step and print options, are..

studies and testing of antireflective (ar) coatings for soda-lime glass. final report

experimental results on this feasibility study to establish processes for producing antireflection films on glass coverings for encapsulated solar cells are very encouraging. efforts have been concentrated in three areas: acid etching of glass, plasma etching of glass, and acid development of sodium silicate films on glass. the best trans..

a study of uremic toxicology

middle molecule (mm) fractions (7a, b, c) obtained by chromatography were each separated in at least two fractions with different mobility and uv-absorption. preparative isotachophoresis proves to be a suitable method for isolation of pure mm compounds. the automatic mm analyzer, which combines gel filtration and ion exchange gradient elu..

six proven ways you can cut health-care costs -- now

the council on wage and price stability issued an extensive report dealing with employee health care benefits and labor and management-sponsored innovations in controlling health care costs six case studies from that report are excerpted and summarized in this article to illustrate proven ways of reducing health care costs the six ways ar..

development of hybrid thermoplastic composites

this program was a three-phase effort. phase i was devoted to evaluatiing compatible fiber surface finishes for thermoplastic matrices. three polysulfone resins (p-1700, pkxa.41 and pkxa.24) from union carbide were evaluated. under phase ii graphite reinforced thermoplastic composites were evaluated for stress cracking in various service ..

structure and mechanical properties of al--al/sub x/o/sub y/ vacuum deposited laminates

high yield strength materials can be fabricated by many techniques a method proposed by koehler is to alternate thin layers of a high shear modulus material with that of a low shear modulus material. the layers must be less than one hundred atomic layers in thickness and be single crystals of similar lattice spacing epitaxially grown on t..
