Leo Roy Beard graduated as a civil engineer in 1939 from Caltech. He worked in water resources development then with the Corps of Engineers until 1972, finally as Direetor of Hydrologic Engineering Center HEC, Davis CA. Beard was in parallel a professor of civil engineering at the University of Texas, Austin, where he had directed the Center for Research in Water Resources from 1972 to 1980. 

A series of unpublished reports is available from Center for research in Water Resources at the University of Texas. 

This project was administered by the Idaho Department of Water Resources Energy Division. We thank the University of Idaho, Aberdeen Research and Extension Center for assistance in separating the straw stems used in the tests Dr. Stephen Aust and Paul Swaner at Utah State University for maintaining and supplying the fungal cultures for inoculum pro-... 

This was developed by Aerometrics in 1983, in collaboration with Lewis Research center, for research into pollution reduction from gas turbines. It is particularly relevent to measurements of small, spherical particles such as are found in fuel injection systems, medical nebulizers and bubbles in water. Aerometrics was later acquired by TSI who currently produce the TSI/Aerometrics PDPA 2D System. This instrument measures sizes in the 0.5 to 10,000 pm range using various optical configurations. The optical transmitter and receiver can be traversed together to move the location of the optical probe for spatial mapping of the flow field and the particle size distributions. 

Formerly known as Chemical Manufacturers Association (CMA). A trade association of chemical manufacturers, representing more than 90 percent of the production for basic industrial chemicals in the US. Administers research in areas significant to chemical manufacturing such as air and water pollution control operates Chemical Transportation Emergency Center (CHEMTREC) to control and report chemical accidents. ACC is organized by industrial groups and also by issue groups that sen>e as coordinators and advocators in their fields of specializations. 

Unitika is a Petrochemical company created in 1889 and which has grown especially into the textile business. Today, their business covers a wide range of economical areas, including financial activities. Its environmental division provides facilities for water treatment, incinerators, air pollution prevention facilities and heavy metal fixing agents. Their R D center conducts research to develop new business areas and products in four segments polymers, environment, advanced materials, and health. 

Lightox A photochemical process for destroying organic materials in aqueous solution by oxidation with chlorine, activated by ultraviolet radiation. Developed by the Taft Water Research Center, United States in the 1960s. 

In the extraction of biologically active compounds, care must be taken to avoid the loss of activity that often occurs by contact with organic diluents. Thus a series of systems have been developed specifically with these compounds in mind. The first of these uses mixtures of aqueous solutions containing polymers and inorganic salts that will separate into two phases that are predominately water. A second system uses supercritical conditions in which the original two-phase system is transformed into one phase under special temperature-pressure conditions. Also the active organic compound can be shielded from the organic diluent by encapsulation within the aqueous center of a micelle of surface active compounds. AU these systems are currently an active area for research as is discussed in Chapter 15. 

Cloud Water and Precipitation Collectors. Several methods have been developed for collecting cloud water samples (24-26). Probably the device most commonly used in warm clouds is the slotted rod collector developed by the Atmospheric Science Research Center at the State University of New York (SUNY) at Albany. Commonly known as the ASRC collector (25), this collector consists of an array of rods constructed from Delrin (a form of nylon). Each rod is hollow and has a slot located at its forward stagnation line. The rod radius determines the collection efficiency as a function of particle size, the rods are sized to collect cloud droplets but not submicrometer aerosol particles, and the 50% cutoff is calculated to be at about 3 xm.

Complementary work on the interaction of oxides with water vapor and the properties of transition metal ions in mineral structures was valuable in pointing the way to some of the variables found significant. These projects are supported, respectively, by the National Science Foundation (GP172) and the Advanced Research Projects Agency, through the Stanford Center for Materials Research.
