University of California field

The University of California field stations have dealt with dilute pesticide waste disposal on an experimental basis by using lined soil evaporation beds. The beds typically are 20 x 40 x 3 ft pits lined with a butyl rubber membrane and back filled with 12 to 18 Inches of sandy loam soli. Figure 1 Is a cross secton of such a bed. Used containers and spray equipment are washed on an adjacent concrete slab the wastewater drains Into a sedimentation box for trapping particulates, followed by a distribution box In the bed. From the distribution box, the dilute pesticide solutions run underneath the soli surface through leach lines made of 4 Inch perforated PVC pipe. The system Is designed so that water moves up through the soli by capillary action and evaporates off the surface. 

Ten University of California field stations located throughout the state (Figure 2) allow for the study of the evaporation beds under several climatic and design variations (Table I). All the evaporation beds were sampled except the one located farthest away, at the Imperial Valley station. The evaporation beds vary In temperature range and annual precipitation, and In such design considerations as size, soil depth, soil pH, the presence or absence of storage tanks, a roof over the bed or slab area, and whether or not the soil Itself has been amended with hydrated lime. The beds also differ In the specific pesticide wastes disposed, and the longevity and Intensity of use.

University of California, San Francisco. The original AMBER has become one of the more widely used academic force fields and extensive work has gone into developing it — resulting in a number of versions of the method and associated parameters. Hyper-Chem gives results equivalent to Versions 2.0 and 3.0a of the AMBERprogram distributed by the Kollman group and parameter sets for both these versions are distributed with HyperChem.

The remaining actinide elements were prepared by various bombardment techniques fairly regularly over the next 25 years (Table 31.1) though, for reasons of national security, publication of the results was sometimes delayed. The dominant figure in this field has been G. T. Seaborg, of the University of California, Berkeley, in early recognition of which, he and E. M. McMillan were awarded the 1951 Nobel Prize for Chemistry. 

In an attempt to develop the hydrogen bomb before the Russians, a second weapons laboratory , Lawrence Livermore, was established in July 1952 to handle the additional work that would be necessaiy to stay ahead of the Russian nuclear weapons program. The administrator chosen was the University of California. Eor the next forty-five years, this LLNL was a formidable competitor to Los Alamos in the development of nuclear weapons. But much like most of the other major national laboratories, its focus also shifted away from nuclear weapons to basic science to fields like magnetic and laser fusion energy, non-nuclear energy, biomedicine, and environmental science. By the late 1990s, half of the laboratoi y s budget was nonde-fense related as the shift away from nuclear weapons continued. 

Townes s academic life continued. He served as provost of MIT from 1961 to 1966. In 1964, Townes received the Nobel Prize in physics for work in quantum electronics leading to construction of oscillators and amplifiers based on the maser-laser principle. He was named university professor at the University of California-Berkeley in 1967. There he worked for more than 20 years in astrophysics. Ironically, this field is one of many that were transformed by die laser, and Townes often tised lasers in his subsequent research. 

Tomato fruits (Lycopersicon esculentum Mill. var. Castlemart ) were collected from vines grown in the field at the University of California, Davis. Pericarp discs were cut from surface sterilized MG stage fruit (10). Droplets (10 n ) of test solutions (see below) were applied to the cut surface of discs and disc ethylene production was measured as described previously (11). The amounts of test materials used were based on colorimetric assay (6) of uronic acid content.

Hancock received his B.A from Harvard and his Ph.D. from the University of Wisconsin in 1968. After a National Institutes of Health Postdoctoral Fellowship at Yale, he worked as assistant and associate professor in the chemistry department of the University of California—Davis from 1968 to 1979, where he taught graduate and undergraduate chemistry and did research in organic and organometallic photochemistry. His work opened a new field of study in organoboron photochemistry. 

The purpose of this article is to review some of the current endeavors in this developing field. To maintain brevity, the focus is on recent studies carried out in our own laboratory and in conjunction with Professor M.T. Bowers at the University of California at Santa Barbara, with emphasis on the use of kinetic energy release distributions and infrared laser multiphoton excitation to probe potential energy surfaces for the reactions of atomic metal ions with alkenes and alkanes.

Ann McCampbell, M.D., is a graduate of the UCLA Medical School and became a licensed physician in California in 1979. She completed an internship in internal medicine in Santa Barbara, and practiced in the field of women s health for five years at the University of California Santa Barbara Student Health Center, and at Kaiser Permanente in the San Francisco Bay Area. Off-hours she played drums in a rock and roll band, and played competitive beach volleyball. 

Susan completed her undergraduate work at the University of California at Berkeley, followed by training and work as a paralegal. Later, in spite of serious chemical and electromagnetic field barriers, she earned a master s degree in disability policy. A divorce was one of the challenges she faced during that chapter of her life. 

Dr. Meng was awarded a Ph.D. from the University of California, Los Angeles, under the supervision of Professor Fred Wudl in 2002. Before joining DuPont Company, he pursued internship training at Lucent Technologies, Bell Laboratories under Professor Zhenan Bao (now at Stanford University) in the field of organic electronics. 

Some of the world s foremost nutrition and medical researchers are now actively involved in developing a better understanding of the field which Dr. Williams pioneered. Rucker and Tinker from the University of California at Davis, Department of Nutrition, have described the role of nutrition in gene expression and its relationship to biochemical individuality as "a fertile field for the application of molecular biology. "6 It is now well known that significant biochemi-... 

The NTP has recently completed a series of inhalation studies in rats and mice, including both noncancer and cancer evaluations. The results of these studies will provide valuable new data on the toxicity of this compound in animals. Dr. W. Kilgore (University of California, Davis) is studying methods for detecting exposure of field workers to bromomethane, and is obtaining data on health effects in these workers. 

No information was located on any on-going studies on the fate and transport of bromomethane. However, two studies related to human exposure to bromomethane are being supported by the U.S. Department of Agriculture and conducted at the University of California, Davis. One project will analyze bromomethane residues on foods, and the second will quantitate exposure levels of field workers to bromomethane and develop appropriate procedures to minimize exposure from this source. Remedial investigations and feasibility studies at NPL sites that contain bromomethane will provide further information on environmental concentrations and human exposure levels near waste sites. 

Twenty years ago two researchers laboring diligently at the University of California at Los Angeles developed the first modified asymmetric membranes which seemed to have commercial potential for what was to become the exciting field that today is known as hyperfiltration or reverse osmosis. Since that time, these dedicated scientists have given freely of themselves and their talents not only to further contribute technically, but also to help guide, teach, and train others to grow in this frontier area. 

In we management systems involving allelopathy, crop varieties may be screened or new varieties developed for their potential for controlling weeds. Such varieties may be left as residues in the field, or be incori rated in every rotation system, and/or used as a companion crop. Similarly, if crop varieties allelopathic to pathogens can be found, their residues can be used similarly for disease control. Research groups of Putnam at Michigan State University and of Gliessman at the University of California are two of many that are involved in research of this kind. 

The experiments were done at the Farm Facility of the Agroecology Program at the University of California at Santa Cruz, where there are facilities for laboratory, greenhouse, and field research. The climate is Mediterranean, and averages 40 inches of rainfall annually. 

Alex Zettl and his colleagues at the University of California, Berkeley, have been active in this field. In 2005, Zettl and his team built an oscillator that is one of the smallest electric motors in the world. The motor works by driving some of the atoms of a tiny drop of liquid metal over to an adjacent and smaller drop. An electric current powers this movement. The most interesting phase of the operation occurs during the rebound, as the atoms return to the original source. This phase happens because of a molecular force known as surface tension. 

He received his B.S. (1945) and Ph.D. (1949) from the University of California, Los Angeles his research advisor was Professor Francis E. Blacet, who first identified the photolysis of N02 as the anthropogenic source of ozone in photochemical air pollution. From 1942 to 1945, he participated in laboratory and field studies in chemical warfare. He was on the faculty at Northwestern University from 1949 to 1954, leaving to join the faculty at the new University of California, Riverside, campus. He was a Guggenheim Fellow at University College, Oxford, in 1961 and a Research Fellow of Merton College, Oxford, in 1965. 

The papers on which the articles in this volume are based, were prepared at the invitation of the organizing committee, for presentation at the Conference on Stochastic Processes in Chemical Physics which was held at the University of California at San Diego, La Jolla, March 18-22, 1968. The purpose of this meeting was to bring together selected experts in the fields of probability theory, applied mathematics, transport processes, statistical mechanics, chemical kinetics, polymer chemistry, and molecular biochemistry for an exchange of ideas and to stimulate interest and activity in the application of the theory of stochastic processes to problems in chemical physics.
