Water Erosion Control, L C. Lightfoot Mar 1952

Water Erosion Control, L C. Lightfoot

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

Although soil erosion caused by water action is common in our agricultural areas, effective erosion control measures, likely to pay for themselves quickly, can be applied in nearly every case. Plant cover above the soil surface, and fertile soil with good structures are the main factors which enable soils to resist erosion. Dense pasture gives the best cover and at the same time improves the fertility and structure of the soil both effectively and economically, so land management adjusted to the need and capability of soils, slopes and climate is of first importance. Contour practices are of secondary value and …


Sunrise And Sunset Times For May-June, 1952 Mar 1952

Sunrise And Sunset Times For May-June, 1952

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 …

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller Jan 1952

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller

Bulletin of the University of Nebraska State Museum (1924–2023)

Until rather recently little has been known of the Drosophila species of Nebraska. Sturtevant (1921) lists Nebraska as one of seven states from which no Drosophila had been reported. Patterson and Wagner (1943) show that collections of Drosophila pseudoobscura had been made in the vicinities of Scottsbluff and Kearney, but no other Drosophila species are reported from Nebraska in their publication.


Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma Jan 1952

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma

Bulletin of the University of Nebraska State Museum (1924–2023)

In 1948 the insect collections at the University of Nebraska State Museum were placed in the care of the author. Prior to that date curatorial duties were assumed or assigned to full time teaching or research staff members. As would be expected under the latter circumstances, the organization of study material and types was neglected in many families and genera. Since 1948 type material, because of its intrinsic value, has received considerable attention. All primary and representative secondary types have been assembled in three museum cases and one slide cabinet for curatorial and study convenience.


On The Ideal Structure Of The Ring Of Entire Functions, Melvin Henriksen Jan 1952

On The Ideal Structure Of The Ring Of Entire Functions, Melvin Henriksen

All HMC Faculty Publications and Research

Let R be the ring of entire functions, and let K be the complex field. The ring R consists of all functions from K to K differentiable everywhere (in the usual sense).

The algebraic structure of the ring of entire functions seems to have been investigated extensively first by O. Helmer [1].

The ideals of R are herein classified as in [2]: an ideal I is called fixed if every function in it vanishes at at least one common point; otherwise, I is called free. The structure of the fixed ideals was determined in [1]. The structure of the …

Kimberley Soils Need Phosphates, W. M. Nunn Jan 1952

Kimberley Soils Need Phosphates, W. M. Nunn

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

Research work carried out at the Kimberley Research Station on the Ord River, and on experimental plots throughout the East and West Kimberleys, indicates that the soils of the Kimberleys are quite as deficient in phosphorus as are the soils of our agricultural areas where superphosphate is essential to the growth of most crops.

This may come as a surprise to many people, for there has been a widespread tendency to assume that the Kimberleys soils, especially those of the Ord and Fitzroy valleys, are highly fertile.

The black earths of Queensland's Darling Downs produce most enviable yields of sorghum …


Soil Conservation In Western Australia, G. H. Burvill Jan 1952

Soil Conservation In Western Australia, G. H. Burvill

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

Soil is a farmer's basic asset. This issue of "The Journal of Agriculture" in a new form designed to provide still better service to the farming community, is an appropriate medium through which to remind the man on the land of what the soil means to him—and to the State. The farmer's duties to himself, his family and the State are summed up in the words "soil conservation" which is merely another way of saying "wise land use."

Waterfowl Breeding Ground Survey, 1952 In Nebraska, Harvey W. Miller Jan 1952

Waterfowl Breeding Ground Survey, 1952 In Nebraska, Harvey W. Miller

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

The Nebraska Breeding Ground Survey has been conducted for the fifth consecutive year. This survey is aimed at providing indicators to the waterfowl population through measuring the seasonal and year b,y year trends in breeding numbers and production success. The survey recognizes the sandhill region as the most important waterfowl-producing area of Nebraska and therefore, studies have been largely concentrated there.

Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke Jan 1952

Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke

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

Audio censuses of Wisconsin game birds were commenced in 1948, and now include the bobwhite quail, the pheasant and the ruffed grouse, in the order in which censuses were introduced.

Briefly, audio censuses are based on the characteristic sounds given by the male of the species concerned during the breeding season. An observer strategically located at a station, or stations in the field tallies the number of individuals calling, and/or the number of calls heard during a given time period.

In Wisconsin, only the transect method is used, with the observer following a given route and making listening stops of …

Separation Of The Alkaline Earth Group By Means Of Paper Chromatography, Robert J. Martinovich Jan 1952

Separation Of The Alkaline Earth Group By Means Of Paper Chromatography, Robert J. Martinovich

Bachelors’ Theses

Since chromatography is beginning more and more to find its place in industry as an analytical tool, the author became interested in its theoretical and practical applications. This thesis was one phase of a project begun by Dr. John G. Surak, to introduce this type of analysis to the freshmen chemistry classes as a supplementary procedure to their regular methods.


A Statistical Comparison Of The Standard And The Modified Karl Fischer Reagents For Moisture Determination In Certain Compounds, Lowell E. Williams Jan 1952

A Statistical Comparison Of The Standard And The Modified Karl Fischer Reagents For Moisture Determination In Certain Compounds, Lowell E. Williams

Bachelors’ Theses

The Karl Fischer reagent may be used for the direct titration of water in liquids, solids, and gases, of either organic or inorganic compounds. Literature shows that the accurate determination of water is quite practical in nearly all classes of organic compounds. Unlike most of the other techniques, which usually are limited in applicability, the Fischer procedure may be adapted readily to quantitative analysis of samples, whose water content may vary from traces to nearly 100 per cent. The reagent, however, has a shortcoming, namely, it deteriorates rapidly. It has recently been suggested that if a two solution procedure were …


Separation Of The Ions Of Groups Iiia And Iiib By Means Of Paper Chromatography, Norman Leffler Jan 1952

Separation Of The Ions Of Groups Iiia And Iiib By Means Of Paper Chromatography, Norman Leffler

Bachelors’ Theses

Since chromatography, In view of its ever increasing importance, may some day largely replace the more traditional methods of qualitative analysis, this research has been aimed not only toward the establishment of a scheme of separation for the ions of group III, but also toward presenting and applying the theoretical principles and basic techniques of this comparatively young branch of analytical science.


The Determination Of Moisture In Active Dry Yeast, Richard F. Fenske Jan 1952

The Determination Of Moisture In Active Dry Yeast, Richard F. Fenske

Bachelors’ Theses

The writer, having been employed for the past three years, in the control laboratory of one of this country's largest yeast concerns, is very much interested in the determination of moisture in active dry yeast and has there­ tore made the investigation presented in this paper.

The moisture content is, of critical importance in the production of active dry yeast. A yeast whose moisture content is too low will have poor baking characteristics while a yeast whose moisture content is too high will have poor keeping quality. Inconsistent results have been obtained by using various methods to determine the moisture …


A Linear Polymer X-Ray Scattering Model, Bernard Cohen Jan 1952

A Linear Polymer X-Ray Scattering Model, Bernard Cohen

Masters Theses

"In the development of X-ray scattering intensity curves physical models are necessary for the theoretical mathematical development involved. The purpose of this paper is the development of a physical model suitable for X-ray diffraction analysis or a linear polymer.

X-ray intensity patterns may be used to give a greater insight as to the atomic structure, configuration or atoms, molecular weight, and therefore a greater knowledge of the structure of matter, both microscopic and macroscopic. The converse may sometimes be used. An atom or molecular model is constructed, from this model X-ray scattering curves may be derived. These curves may be …
