Wind Erosion And Sand Blasting, E E. Rowley

Journal of the Department of Agriculture, Western Australia, Series 4

Wind erosion and sand blasting of crops and pastures have been frequent hazards to many south coast sandplain farms ever since land clearing started there. In 1980 and 1981 the problems were particularly severe, resulting in widespread crop and pasture losses. Pastures are at risk as the amount of available dry feed declines in late summer, autumn and early winter, but cultivated paddocks with emerging crops usually suffer the most serious economic and physical effects. Wind-caused problems have serious implications for agriculture on these sandplain areas. Apart from the serious annual production losses, four or five consecutive years of serious …

Ware River Intensive Watershed Study - Part 2. Estuarine Receiving Water Quality, Cindy Bosco, Gary F. Anderson, Bruce Neilson

Reports

The Ware River Intensive Watershed Study contains results of runoff from small catchments, instream transport of runoff and the impacts on estuarine water quality, which are contained in two volumes: 1. Nonpoint Source Pollution and 2. Estuarine Receiving Water Quality

Estuarine Studies: The Ware River is a relatively "clean" estuarine system. However, during summer months some of the nutrients, particularly inorganic phosphorous and organic nitrogen, achieve levels associated with moderate enrichment. The Ware is typical of other small tributaries of Chesapeake Bay: nutrient levels are higher at low tide, the estuary is more homogenous laterally than longitudinally, and vertical gradients …

The Preparation Of The Coordination Compounds Of Palladium (Ii) And Spermine And Spermidine, Wenli Grace Lee

University of the Pacific Theses and Dissertations

The purpose of this study was to prepare and characterize complexes produced by the reactions of spermine and spermidine with palladium(II) chloride. A first analysis of the problem seemed to indicate that preparation of the complexes should be straightforward and not difficult. Bonding of the nitrogen atoms to the metals allows sterically for formation of two six-membered rings separated by a tetramethylene chain in a spermine complex, and by a six-membered chelate ring in a spermidine complex.

Palynological Differences Between The Chuckanut And Huntingdon Formations, Northwestern Washington, Kenneth Norman Reiswig

WWU Graduate School Collection

Pollen and spore assemblages from the Tertiary coal-bearing Chuckanut and Huntingdon Formations were studied to determine the existence and location of the southern boundary of the Bellingham Basin. Ages of deposition were determined for each formation based on the flora recovered. The age of the Chuckanut Formation ranges from Middle Paleocene at its base to Late Eocene at its top. The age of the Huntingdon in northwestern Washington is Late Eocene to perhaps Earliest Oligocene. From the evidence of palynomorph ranges, no definite age breaks were found within the Chuckanut Formation, or between the Chuckanut and Huntingdon Formations. The structure …

Robotics And The Conservation Of Human Resources, Robert U. Ayres, Steven M. Miller

Research Collection School Of Computing and Information Systems

Due to rapid expansion in the field of robotics, policy issues have arisen in regard to developing human skills to deal with the new technology and to deal with the obsolescent human skills which are the inevitable result of this growth pattern. Industrialists, educators, union leaders, and government officials must work cooperatively to insure that the coming changes are made with minimum disruption. Improved training methods and courses have to be developed for the skills needed to control, manage and supervise the new machines. Some of the ways in which this can be accomplished are through offering financial incentives for …

Anisotrophy In Mhd Turbulence Due To A Mean Magnetic Field, John V. Shebalin

Dissertations, Theses, and Masters Projects

The development of anisotropy in an initially isotropic spectrum is studied numerically for two-dimensional magnetohydrodynamic (MHD) turbulence. The anisotropy develops due to the combined effects of an externally imposed dc magnetic field and viscous and resistive dissipation at high wave numbers. The effect is most pronounced at high mechanical and magnetic Reynolds numbers. The anisotropy is greater at the higher wave numbers.;The statistical structure of two-dimensional MHD turbulence is also considered. It is shown that the three known rugged invariants of the isotropic case reduce to two for the anisotropic case. Randomness and ergodicity are also briefly discussed.

A Classification Of Certain Graphs With Minimal Imperfection Properties, S. H. Whitesides

Dartmouth Scholarship

The family of (α, ω) graphs are of interest for several reasons. For example, any minimal counter-example to Berge's Strong Perfect Graph Conjecture belongs to this family. This paper accounts for all (4, 3) graphs. One of these is not obtainable by existing techniques for generating (α + 1, ω) graphs from (α, ω) graphs.

The Water Requirements And Pollutant Potential In The Gasification Of Carbonaceous Shales, Jeffery A. Cissell, V. Dean Adams, Joel E. Fletcher, Daniel S. Filip, Dennis B. George

Reports

A laboratory-scale, batch operated gasifier was used to evaluate the heating value, process and cooling water requirements, and water pollution potential of gasification of carbonaceous shales. These potentially valuable fossil fuels are found over large areas of Southern and Eastern Utah and vary widely in quality depending on the amount of intermixed inorganic material. The results indicate that a synthesis gas, consisting primarily of hydrogen and carbon monoxide, can be produced from carbonaceous shales. The total heating values of the synthesis gas from the carbon shales examined ranged from 4 to 62 percent of that of coal. The process water …

Salt Loading From Efflorescence And Suspended Sediments In The Price River Basin, David S. Bowles, Hooshang Nezafati, Rao K. Bhasker, J. Paul Riley, R. J. Wagenet

Reports

Salinity control is a major component of water management in arid climates and irrigated areas and one of particular concern in the Colorado River Basin. The alts enter the water as it flows over land or moves through the soil or geologic formations. The principal salt collection processes are 1) dissolution from the soil surface during runoff events, 2) transpiration of soil water leaving salt residuals, 3) efflorescence left by evaporating seepage and then dissolved by subsequent runoff, 4) dissolution with weathering of fixed bed channels, 5) salts released by sediments entering the channel from sheet, gulley, and bank erosion, …

A water quality study was conducted between May 1977 and August 1978. Samplse were collected from the Animas River, which will provide the inflow to the proposed reservoir, and from the La Plata River, which will receive discharge from the reservoir. Samples …

Sprinkler Application Of So2 - Treated Groundwater At The Sandarosa Farm, Snowville, Utah, V. Dean Adams, Craig S. Criddle

Reports

Sulfur is recognized as one of the essential elements for plant growth. It has also been used in agriculture for reclamation of saline and sodic soils. During the reclamation process there is the potential benefit of increased availability of phosphorus and certain micro-nutrients for plant uptake. There is also potential for increased infiltration thus increasing water utilization efficiency.

Sulfur has been applied to soils in a flake or nodule form, by the addition of sulfuric acid and most recently by the application of sulfurous acid. The raw sulfur addition technique is accomplished by spreading raw sulfur on the soil and …

Benthic Resting Cysts Of Gonyaulax Monilata Howell And Their Relationship To Red Tides In The Indian River, Florida, Kevin C. Owen, Dean R. Norris

Ocean Engineering and Marine Sciences Faculty Publications

Gonyaulax monilata cysts were found in the sediments from 13 of 37 stations sampled in the Indian River, Florida. The distribution of cysts appears to be the result of 2 unrelated phenomena. In areas where blooms have occurred in the past, the lack of circulation in the lagoon allows the cysts to accumulate. South of Turkey Creek, cysts are found associated with shellfish beds where no blooms have been reported. It is suggested these cysts have been introduced into shellfish regions with oysters which are annually rafted from areas where G. monilata blooms occur. Blooms of this toxic dinoflagellate can …

The Distribution And Properties Of Lateritic Gravels At Yalanbee And Their Interactions With Soil Phosphorus, David Weaver

All other publications

This study aimed at investigating the distributive patterns and properties of lateritic gravels at "Yalanbee" (C.S.I.R.O. research station) and how these properties and patterns e ffect the adsorption of phosphorus onto the lateritic gravels. It also aimed partly at investigating the effect of the presence of lateritic gravels on the adsorption of phosphate by "whole soils". Gravels in the Yalanbee soil had migrated since their formation as was shown by their abundance and large size at the top of a slope which graded to less abundant, smaller and more rounded gravels further down the s lope. The distribution of gravels …

A Brightening Of The Symbiotic Variable Sy Muscae, A. G. Michalitsianos, Menas Kafatos, W. A. Feibelman, G. Wallerstein

Mathematics, Physics, and Computer Science Faculty Articles and Research

The symbiotic variable SY Muscae has been observed with IUE in September 1980 and June 1981 and in the photographic region in May 1981. The entire ultraviolet spectrum brightened between September and June by about a factor of 5. The spectrum shows high excitation including emission from N v and high electron density, about 10^10 cm^-3 as determined from various line ratios in the ultraviolet. The optical spectrum is dominated by permitted lines; even [0 m] is very weak again indicating high density in the ionized region. The increase in ultraviolet continuum and line emission may be due to enhanced …

A Water Quality Study Of The Northwest River, Virginia, Albert Y. Kuo, Bruce Neilson, Paul V. Hyer

Reports

The Northwest River is a small, coastal plains river lying to the south of the Hampton Roads metropolitan area. It flows in a southeasterly direction from the Dismal Swamp, its headwaters, to North Carolina where it empties into Currituck Sound. Lunar tides in the river are quite small, but flow reversals due to winds are not uncommon.

Previous studies of the river have evaluated its potential as a drinking water source and the environmental changes that would occur as a result of water withdrawal. The latter concern was primarily that downstream locations would experience higher salinity levels once fresh water …
