Impacts Of Projected Climate Change On Urban Water Use, United States Department Of The Interior, Bureau Of Reclamation

Water

Urban water use, particularly outdoor use, responds to changes in temperature, precipitation, and other climatic parameters. This study significantly improved the capacity of an existing regional water demand model to estimate the response of both residential and commercial-industrial water demand to changes in climatic parameters. The resulting functional relationships derived from historic time-series climatic and water use data were applied to global climate scenarios for the four Wasatch Front counties of Utah.

Bulletin 4278 - How To Use Wide Furrow Sowing For Improved Crop Production On Water Repellent Sand, Paul Blackwell, Grant Morrow, Tony Webster

Bulletins 4000 -

Wide furrow sowing is a method for successfully establishing crops of lupins or cereals on non-wetting sands, and improving crop establishment on non-repellent sands. The same principles can be used to assist establishment of fodder shrubs and long-term pasture (e.g. tagasaste and Rhodes grass).

Pyrolysis And Oxidation Reaction Of 1,2, Dichloroethylene In Ar; Ar And Ch4; Ar, Ch4 And O2 Mixtures, Byung Ik Park

Theses

The thermal reaction of trans-1,2-dichloroethylene (DCEE) in methane and oxygen mixtures in Ar bath gas has been studied in 10.5 mm I.D. tubular flow quartz reactors at I atmosphere pressure, isothermal temperature between 575°C and 1000°C, and times of 0.3 to 2.0 seconds.

The thermal reaction of trans-1,2-dichloroethylene in the gas phase proceeds via unimolecular HCI elimination under the reaction condition of the present experiments. The chain branching C-Cl bond fission reaction is expected to become important at the higher temperature, competing With the HCI elimination.

The decay trans- 1,2- dichloroethylene, intermediates and final product distributions varied in the absence …

This study was performed to find a satisfactory regime of operation for the vapor phase bio-oxidation of ethyl alcohol, a model volatile organic compound (VOC), in a specially designed bioreactor. Ethanol was selected as a model compound representing bakery oven gas pollution. A spirally wound bioreactor module was used within which was immobilized a mixed bacterial culture from aerobic sludge. The activated sludge from municipal wastewater treatment plants readily attached with no pretreatment on the surface of the spiral biosupport which is a polymeric sheet.

The parameters studied were air flow rate and inlet concentrations of ethanol. Ethanol was injected, …

Study On The Remediation Of Organic Soil Contaminated With Polychlorinated Biphenyls Using A Variable Frequency Microwave Furnace, Lili Zou

Theses

The development of new and innovative remediation technologies for soil contaminated with Polychlorinated Biphenyl (PCB) is necessary to fulfill the need of cleanup of contaminated sites. In the past eight years the Laboratory for Microwave treatment as Hazardous Substance Management Research Center has investigated the use of Microwave energy to remediate contaminated soils. A major drawback of using single frequencies of the microwave range is the non-uniformity of the electromagnetic field. In this thesis a Variable Frequency Microwave Furnace (operating between 2.40 and 7.50 GHz) is used to improve the uniformity of the field. A new method is used to …

Study Of The Leaching Of Pentachlorophenol From Treated Utility Poles, Jingyi Zhang

Theses

Pentachlorophenol ( PCP ) has been used as a preservative in wood industry over 40 years. If new regulations are passed, the disposal of used treated utility poles in landfills could be restricted because of the toxic properties of PCP. This study was undertaken to provide a better understanding of the rates and mechanisms of leaching of PCP from these poles.

Following the initial analytical method development for PCP determination, a study was done to apply and validate the method in a leaching characteristics study of PCP from Douglas Fir and Southern Pine.

The major factors which influence the leaching …

Pedogenic Processes In Thick Sand Deposits On A Marine Terrace, Central California, Lynn E. Moody, R. C. Graham

Natural Resources Management and Environmental Sciences

Pedological studies in thick sedimentary sequences are generally limited to the upper few meters. Field investigation of thick (~50 m) sand deposits on an emergent Pleistocene marine terrace in central California showed morphological differences between the solum at the surface and the deep regolith. Based on morphological and geochemical features, four units were identified within the regolith. Two zones of active pedogenesis occur within three of these units. The surficial unit is in Holocene sand deposits (mixed, thermic, Argic Xeropsamments), and has darkened A horizons, a slightly reddened subsoil, and incipient lamellae at the depth of wetting front infiltration. These …

Size Distribution And Scattering Phase Function Of Aerosol Particles Retrieved From Sky Brightness Measurements, Y. J. Kaufman, A. A. Gitelson, A. Karnieli, E. Ganor, R. S. Fraser, T. Nakajima, S. Mattoo, B. N. Holben

School of Natural Resources: Faculty Publications

Ground-based measurements of the solar transmission and sky radiance in a horizontal plane through the Sun are taken in several geographical regions and aerosol types: dust in a desert transition zone in Israel, sulfate particles in Eastern and Western Europe, tropical aerosol in Brazil, and mixed continental/maritime aerosol in California. Stratospheric aerosol was introduced after the eruption of Mount Pinatubo in June 1991. Therefore measurements taken before the eruption are used to analyze the properties of tropospheric aerosol; measurements from 1992 are also used to detect the particle size and concentration of stratospheric aerosol. The measurements are used to retrieve …

A River Ran Through It... : The Cultural Ecology Of The Santa Clara Valley Riparian Zone, Erin M. Reilly

Research Manuscript Series

This study addresses the nature of human interaction with the riparian environment in the Santa Clara Valley over time. This is not a new anthropological theme. Literature dates to 1863 The Earth as Modified by Human Action, by George P. Marsh); cultural ecologist Betty J Meggars stated: "The relationship- of culture to environment is one of the oldest problems in the science of anthropology ... "(Meggars, 1968:19); and, anthropologist Alfred Kroeber said: "no culture is wholly intelligible without reference to the nonculture, or so-called environmental factors with which it is in relation and which condition it "(Kroeber 1906:297).

Learning About Ethical Outdoor Leadership, Karen Fox, Mark Reed

Research in Outdoor Education

Outdoor adventure programming has responded to changing societal and individ­ual needs by enlarging the goals and objec­tives of programs beyond the boundaries of the outdoor trip. Program missions, goals and objectives regularly include integrating people with and without disabilities, rein­forcing appropriate school and societal be­haviour in youth at risk, enhancing the self­ esteem of young people, teaching environ­mentally sound behaviour, and enhancing restorative healing for women survivors of abuse and people with terminal illness. These broader goals and objectives place different demands upon the outdoor leader and situate an outdoor trip within a larger context. This larger context connects out­door …

Moods Of 3-Week And 5-Week Outdoor Expedition Participants, Pamela E. Foti, Suzanne R. Daiss

Research in Outdoor Education

The purpose of this research project was to investigate and document the cycle of mood states displayed by outdoor recreation expedition participants. It was hypothesized that an individual's moods pass through a predictable cycle during the beginning, middle, and end phases of a 3-week to 5-week outdoor expedition.This cycle would include fluctuations in mood states such as anger/hostility, confusion/bewilderment, de­pression/dejection, fatigue, tension/anxiety, and vigor. It was anticipated that ten­sion/anxiety would be high in the beginning, medium to high in the middle, and then low at the end. Depression/dejection was ex­pected to be low in the beginning, high in the middle, …
