Oregonator

The behaviour of the BZ system ean be modelled semi-quantitatively by the oregonator model [15] ... 

Much use has been, and continues to be, made of simplified model schemes representative of general classes of chemical or themial feedback. The oregonator and Lengyel-Epstein models for the BZ and CDIMA systems have been given earlier. Pre-eminent among the more abstracted caricature models is the bnisselator introduced by Prigogine and Lefever [47] which has the following fomi ...

Linus Pauling (1901-1994) was born in Portland Ore gon and was educated at Oregon State University and at the California Institute of Technology where he earned a Ph D in chemistry in 1925 In addition to re search in bonding theory Pauling studied the structure of proteins and was awarded the Nobel Prize in chemistry for that work in 1954 Paul ing won a second Nobel Prize (the Peace Prize) in 1962 for his efforts to limit the testing of nuclear weapons He was one of only four scientists to have won two Nobel Prizes The first double winner was a woman Can you name her" ... 

Soil. Composting of soils contaminated by high explosives is being carried out at the Umatilla Army Depot near Hermiston, Oregon (70). Soil from munitions washout lagoons is being treated iadoors ia compost rows of 2,000 m, and the estimated cost is less than one-third the estimated cost of iaciaeration. If this is successful, there are 30 similar sites on the National Priority List that could be treated ia a similar way.

Georgia, Idaho, North Carolina, and Oregon also have some reserves. 

Total hafnium available worldwide from nuclear zirconium production is estimated to be 130 metric tons annually. The annual usage, in all forms, is about 85 t. The balance is held in inventory in stable intermediate form such as oxide by the producers Teledyne Wah. Chang (Albany, Oregon) and Western Zirconium in the United States Ce2us in France Prinieprovsky Chemical Plant in Ukraine and Chepetsky Mechanical Plant in Russia (crystal bar). 

Hectorite usually contains 0.3—0.6% Li or 0.7—1.3% Li20. Deposits are found in Nevada, California, Utah, Oregon, Wyoming, Ari2ona, and New Mexico. 

The most significant deposits are in southern Nevada, in the Lake Mead area, and in the McDermitt caldera complex on the Nevada—Oregon border. In the McDermitt caldera, lithium probably originated from volcanic sedimentary rocks deposited in the caldera moat. There is evidence that areas of the caldera were hydrothermically active contributing to enrichment of lithium (14). This and other similar deposits are not economically viable as of this writing. These deposits do represent a significant lithium reserve, however, whenever large expansion in demand occurs. 

The main growing areas for badey are North Dakota, Montana, eastern South Dakota, and western Minnesota six-row badey is predominant. Increasingly significant areas are California, Oregon, Washington, Idaho, and Colorado, where predominandy two-row badey is produced. Less than one-half of the badey grown in the United States is processed by the malt industry the remainder is used as animal feed, and ca 80% of the badey used by the malting industry is the six-tow variety (2—5) (see Feeds and feed additives, pet foods). 

English or Persian Walnuts. Walnuts are produced in more countries than any of the other tree nuts but production figures are unrehable. The United States is the leading producer of walnuts, at 234,913 t in 1990—1991 (valued at 279,720,000). Production, mostly in Califomia and Oregon, is nearly one-half of the world total. Many countries produce substantial quantities of walnuts. The USDA considers estimates of the commercial crop more rehable than the total yearly production figures, which in 1990—1991 were 152,500 t in China, 66,000 t in Turkey, 17,000 t in India, 13,000 t in Prance, and 12,000 t in Italy. Walnuts, both in-sheU and shelled, may be imported from many countries, eg. Prance, Italy, China, Turkey, and India. Most imported walnuts are smaller than domestic walnuts and are used by the confectionery and baking industries. 

Waste Recovery, Inc. (WRJ) shreds tires for fuel at installations in Pordand, Oregon Adanta, Georgia MarsiU.es and Du Po, Illinois Conshohocla, Peimsylvania and Houston, Texas. Goodyear owns - 10% of WRJ. Firestone bums rejected tires in addition to other soHd wastes. 

Conrad Industries, Inc. (CentraUa, Washington) and Clean Air Products Company (Pordand, Oregon) have jointiy built a tire pyrolysis demonstration machine which allows recovery of combustible gases, oils, and other by-products. The equipment can also handle other carbonaceous material. It is designed to process 0.9 t/h of tires the entire system is estimated to cost about 2.3 x 10 . The feedstock consists of 5-cm tires chips which produce pyrolytic filler, a vapor gas yielding 11.5 kj/m (1000 Btu/ft ), and medium and light oils yielding about 42 MJ/kg (18,000 Btu/lb) (32).
