Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy Jul 1969

Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy

Masters Theses & Specialist Projects

This research was part of a project underway at Barren River and Nolin River Reservoirs in south-central Kentucky. The research was partially supported by a grant through the Sport Fishing Institute, Washington, D.C.

The study reported herein was concerned with the analysis of trace metal concentrations in the two reservoirs. It is believed that the fish population may in part depend upon the trace metals present in the water. It is anticipated that the data presented in this paper will eventually be correlated with the biology studies of the reservoirs being carried out by the Department of Biology of Western …


Chemistry Of The Oxidant, Ferrate, Its Interaction With Specific Organics Found In Waste Water, Donald H. Williams, J. T. Riley Jul 1969

Chemistry Of The Oxidant, Ferrate, Its Interaction With Specific Organics Found In Waste Water, Donald H. Williams, J. T. Riley

KWRRI Research Reports

It became obvious during this investigation that while much work has been done with ferrate (VI) chemistry, discrepancies existed in the literature and very little attention had been given possible engineering uses. This work attempted to fulfill these two needs in an exploratory manner.

The preparative techniques were reviewed and mechanical improvements made in one which allowed improved yields. Essentially what was done was to enlarge and improve the filtering technique of the product and use cooler temperatures throughout the preparation. This greatly shortened the time required. Then it was learned that the addition of ethyl alcohol to the final …

Solution Geochemistry Of The Water Of Limestone Terrains, John Thrailkill, David B. Beiter, Michael T. Osolnik, Roger H. Postley, William T. Mitchell, Leonard N. Plummer, James R. Riddell, Richard C. Worley, Robert D. Zwicker

KWRRI Research Reports

Limestone groundwater flows mainly in openings it has solutionally enlarged, thus an understanding of the water's state of saturation relative to calcite (the principal mineral component of limestone) is fundamental to an understanding of the nature and evolution of the limestone aquifer. This study investigated the Mammoth Cave-Sinkhole Plain (MCSP) and Cave Hollow (CH) aquifers in Kentucky, both in Missippian limestones.

Both aquifers were always undersaturated with calcite. Except for completely ventilated vadose flows (usually) and some vadose seepage (occasionally), all recharges sampled (sinking streams, vadose flows, and vadose seepage) were also undersaturated. The lack of saturation in the MCSP …

Subsurface Irrigation Research In Arkansas, John P. Hoskyn, Billy B. Bryan Jun 1969

Subsurface Irrigation Research In Arkansas, John P. Hoskyn, Billy B. Bryan

Arkansas Water Resources Center Technical Reports

A pilot study conducted in 1963 indicated that (1) cotton yields could be increased by subirrigation, (2) drilled orifices were unsatisfactory because of internal plugging caused by burrs and drilling particles, and (3) operating pressures of 5 and 10 psi were excessive, and 5 psi probably should be considered as an upper-limit pressure. A greenhouse study of a subirrigation system indicated that 2 psi should, in general, for in-wall orifices, be considered as a lower-limit pressure when orifices are built into the pipe wall. The greenhouse study also indicated that a placement depth of 12 inches was preferable to 18 …

Taxonomy Of The Common Dolphins Of The Eastern Pacific Ocean, Richard C. Banks, Robert L. Brownell Jr. May 1969

Taxonomy Of The Common Dolphins Of The Eastern Pacific Ocean, Richard C. Banks, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Delphinus bairdii Dall is a species of dolphin distinct from D. delphis Linnaeus, with which it has usually been synonymized. D. bairdii has a longer rostrum relative to the zygomatic width of the skull; the ratio of these measurements falls at 1.55 or above for bairdii and 1.53 and below for delphis. In the eastern Pacific Ocean, D. bairdii is found in the Gulf of California and along the west coast of Baja California, Mexico; D. delphis is presently found in the waters off California. Until approximately the beginning of the present century, bairdii occurred farther north in the …

Land Use Changes And Sharp-Tailed Grouse Breeding Behavior, Leonard H. Sisson Apr 1969

Land Use Changes And Sharp-Tailed Grouse Breeding Behavior, Leonard H. Sisson

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The sharp-tailed grouse formerly inhabited much of the area which is now Nebraska. The sharp-tailed, along with its near relative, the greater prairie chicken, disappeared from parts of its former range which were put into intense cultivation. The 20,000 square mile area of the Sandhills were not suited to such cultivation and consequently is the remaining stronghold of the sharp-tailed in Nebraska. It is one of the more important sharp-tail ranges remaining in the United States.

With continuing decreases in suitable sharp-tail habitat throughout its former range in the United States, it is important to understand land use trends and …

West Midlands Development : Soil Map Used To Group Similar Soils Into Land Use Classes, Department Of Agriculture, Western Australia

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

Selection of areas for initial treatment is basic to economic development of blocks in the West Midlands.

Obviously, it is best to develop large areas of the most productive "land use classes" first in order to obtain the highest and earliest returns on capital.

Barramundi are widely distributed in rivers and estuaries in the semi-tropical and tropical regions of the Indo- Pacific from South China to the Persian Gulf and along the coast of northern Australia. The limiting factors to the distribution appear to be temperature and salinity.


Flora And Fauna Conservation : A Plea To Landholders, Clee Francis Howard Jenkins Jan 1969

Flora And Fauna Conservation : A Plea To Landholders, Clee Francis Howard Jenkins

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

MUCH of the recent discussion on conservation has centred around the importance of wild flower reserves and the necessity for protecting one of the State's most important tourist attractions.

Although less important to visitors than the flowers, many of our wild animals hold equal interest for nature lovers and scientists, and they also need protection.

Water Storage Has Not Kept Pace With Stock Numbers : South Stirling Survey Finding, A L. Prout Jan 1969

Water Storage Has Not Kept Pace With Stock Numbers : South Stirling Survey Finding, A L. Prout

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

RESULTS of a survey on water storage capacity in the South Stirlings area indicate that farm water storage has not kept pace with increased clearing and stock numbers.

This has resulted in many farmers requesting advice on water conservation projects following two consecutive years of low rainfall runoff.


Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon Jan 1969

Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon

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

Neonatal lamb mortality is often high in Western Australia and losses as high as 33 per cent, have been recorded on private properties in the Esperance area. Surveys by Western Australian Department of Agriculture officers have indicated that more than threequarters of such lamb deaths occur after birth. About half these deaths result from the combined effects of weather and mismothering.

Work in Victoria has indicated that lamb mortality may be reduced by intensive lambing systems such as shedding and this trial was established to see if shedding could reduce lamb mortality in the Esperance environment.


Honey Plants In Western Australia, F. G. Smith Jan 1969

Honey Plants In Western Australia, F. G. Smith

Bulletins - 3000 - 3999

Successful honey production depends, among other things on a good knowledge of the plants which produce nectar.

Every apiarist needs to know which plants are of importance to honey-bees, where those plants occur, and when they flower. He also needs to know which plants produce nectar which will result in the production of good quality honey, and which produce unpalatable or unmarketable honey. To maintain the strength of his bee colonies he also needs to know which plants produce nutritious pollen.

The object of this bulletin is to provide the basic information on these subjects in the main beekeeping areas …
