A Study Of The Kinetics And The Free Radicals Involved In The Low-Pressure, Vapor-Phase Pyrolysis Of Toluene, Robert E. Williams Dec 1952

A Study Of The Kinetics And The Free Radicals Involved In The Low-Pressure, Vapor-Phase Pyrolysis Of Toluene, Robert E. Williams

Chemistry and Chemical Biology ETDs

The separation of lanthanum, yttrium, and the rare earth elements from their ores has been a challenge to the chemist for many years. The similarities in chemical properties has made their separation a problem of extraordinary difficulty. Fractional crystallization has been the classical method utilized in the past, although individual elements have been isolated by oxidization or reduction to other than the tripositive oxidation state (1). Recently ion exchange and solvent extraction methods have become more important as a means of separation of these elements. Both of these techniques depend upon fractional differences in the distribution of compounds or ions …


A Theoretical Formulation Of The Hammett Equation, Gordon A. Gallup, W.R. Gilkerson, M.M. Jones Dec 1952

A Theoretical Formulation Of The Hammett Equation, Gordon A. Gallup, W.R. Gilkerson, M.M. Jones

Gordon Gallup Publications

A relation, which reduces to the form of Hammett's equation, has been derived. Reactions which can be assumed to be of the form ion-dipole or dipole-dipole have been considered. The logarithms of the ratios of rate constants were calculated and compared with experimental values in the form of Hammett's equation constants.

The Regeneration And Maintenance Of Wimmera Ryegrass Pastures Under Saline Soil Condition, F L. Shier Nov 1952

The Regeneration And Maintenance Of Wimmera Ryegrass Pastures Under Saline Soil Condition, F L. Shier

Journal of the Department of Agriculture, Western Australia, Series 3

Over the past ten years, Wimmera ryegrass pastures at the Salmon Gums Re- VJ search Station have been improved and maintained by periodic cultivation of the soil even without applications of superphosphate. On heavy crab-holey soil affected by high salt content and unsatisfactory for wheat growing, cultivation treatments have produced remarkably uniform stands of Wimmera ryegrass as shown in the accompanying pictures. The bare patches due to salt, have been largely eliminated. If the interval between cultivations is more than three years Wimmera pastures deteriorate badly.


Sunrise And Sunset Tables Times For Jan.-Feb., 1953 Nov 1952

Sunrise And Sunset Tables Times For Jan.-Feb., 1953

Journal of the Department of Agriculture, Western Australia, Series 3

Times of sunrise and sunset for every fifth day, are given for a number of towns throughout the State. Times for a town not on the list may be estimated if its position in relation to one or more of the listed towns is known. The times given for sunrise are those of the first appearance of the top edge of the sun over a true horizon; those for sunset give the time of the sun's disappearance below a true horizon. Situation in a valley would make the sun appear to rise later, and on a hill it would appear …


Soil Conservation Service - Basis Of Co-Operation, G H. Burvill Nov 1952

Soil Conservation Service - Basis Of Co-Operation, G H. Burvill

Journal of the Department of Agriculture, Western Australia, Series 3

The Soil Conservation Service has been established as provided in the Soil Conservation Act, 1945. To carry out its objectives will require the co-operation with it of individual farmers and landholders. The policy of the Service is therefore to encourage farmers to help themselves, and particularly to encourage them to recognise the need for soil conservation methods and for soil erosion control in the early stages. More particularly, the Service aims to provide, through its trained staff, technical asistance in the way of agricultural advice, research, conservation, planning, layouts and surveys. As indicated below, under the heading "Charges for Soil …

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne Nov 1952

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Studies of drift thickness and character currently in progress in Indiana indicate changes in drainage that have occurred in Indiana and some adjoining states since the beginning of the Pleistocene epoch. After late Tertiary (Lexington) peneplanation the master-drainage line, the Mahomet-Teays Valley system, became entrenched about 200 feet below its former level before it was ponded by Nebraskan ice and diverted into a new course. During the Parker cycle, which was interrupted by glaciation, the present physiographic features of southern Indiana and their now buried extensions to the north became recognizable. Static rejuvenation then was a major factor in erosion …

This report and any related files are made available to the online through the Lester F. Larsen Tractor Test and Power Museum as resources allow. Established in 1998, this museum is located on the University of Nebraska-Lincoln East Campus. It is and appropriately housed within the walls of the historic 1920 Nebraska Tractor Test Laboratory, where the first tractor test was started on March 31st, 1920. Because the pioneer tests became worldwide standards, this location was designated as a Historic Landmark of Agricultural Engineering by the American Society of Agricultural Engineers in 1980, shortly after testing was moved to a …

Report On Historical Investigation Of Wounded Knee Battlefield Site, Pine Ridge Indian Reservation, South Dakota, Merrill J. Mattes Oct 1952

Report On Historical Investigation Of Wounded Knee Battlefield Site, Pine Ridge Indian Reservation, South Dakota, Merrill J. Mattes

United States National Park Service: Publications

In April 1952, the National Park Service was requested by Representative E. Y. Berry of South Dakota, to consider the possibility of giving national recognition to Wounded Knee Battlefield, on the Pine Ridge Indian Reservation of South Dakota. Limited Date on the battlefield was presented on April 22 to the Advisory Board on National Parks, Historic Sites, Buildings, and Monuments. The Board asked that a field investigation and report be made by the Service to secure more comprehensive data. The Region Two office was requested to conduct this investigation by a note appended to Mr. Tolson's letter of May 9 …

Internal Fissuring Of Wheat Due To Weathering, Max Milner, J. A. Shellenberger, M. R. Lee, Robert Katz Sep 1952

Internal Fissuring Of Wheat Due To Weathering, Max Milner, J. A. Shellenberger, M. R. Lee, Robert Katz

Robert Katz Publications

Radiographic technique developed at this Station for the determination of internal or hidden insect infestation in stored grain has proved to be useful for the detection of other physical anomalies in grains. Practical applications of this sort include the detection of cracked or broken kernels in rough rice (paddy) prior to milling as well as the extent of internal fracturing of certain grains such as maize due to uneven stresses arising from severe drying conditions. This communication deals with a condition of internal fissuring occurring in wheat due to weathering of the ripened grain in the field.

Soil-Saving Schools Sep 1952

Soil-Saving Schools

Journal of the Department of Agriculture, Western Australia, Series 3

Save the soil for your sons and grandsons," or "Every farmer his own soil conservationist" might well serve as slogans for the recently-inaugurated farmers' schools organised in this State by the Soil Conservation Service. Judging by the enthusiasm shown by pupils at the first two schools, held in August last, this highly practical approach to an important subject seems destined to usher in an entirely new conception of soil conservation work as it affects the individual land-owner.

The Hose U-Tube Level, J P. Fallon Sep 1952

The Hose U-Tube Level, J P. Fallon

Journal of the Department of Agriculture, Western Australia, Series 3

With the growing use of soil conservation practices throughout the farming areas, there has been an increasing demand for a simple levelling device that will enable farmers to take their own levels. When they have become familiar with the use of pasture furrows, contour banks and the various other mechanical erosion control measures, farmers with the aid of such an instrument would be able to make an immediate start on an erosion control programme. The instrument would also prove useful for numerous small jobs around the farm when accurate levels are required. Tests have shown the "Hose U-Tube Level" here …
