North Of The Nullarbor Plain, A. R. Tomlinson, C. K. Blair Jan 1952

North Of The Nullarbor Plain, A. R. Tomlinson, C. K. Blair

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

For a few hardy dingo-trappers—experienced bushmen able and willing to endure the rigours pf a nomadic existence in a waterless country - the area to the north of the Nullabor Plains has long been a favoured watering ground. In the 1949-1950 season bounties were paid on about 3,000 dingo scalps from this area.


Life Cycle Studies On Stephanostomum Pacificum, A New Species Of Trematode, From The Pacific Marine Station Area, James Frank Hughes Jan 1952

Life Cycle Studies On Stephanostomum Pacificum, A New Species Of Trematode, From The Pacific Marine Station Area, James Frank Hughes

University of the Pacific Theses and Dissertations

This report summarizes the results of a study on the life cycle of a member of the trematode family Acanthooolpidae, genus Stephanostomum Looss, 1899, which was carried on during the summers of 1948, 1949, 1951, and the winter of 1948-49 at the Marine Station of the College or the Pacific at Dillon Beach, California. Only one previous experimental work has been done on the life cycle of any member of this family. Martin (1939) reported the life cycle of Stephanostomum tenue (Linton) which he had obtained at Woods Hole, Massachusetts. Modifications of his technical procedures have been used in this …

Red-Backed Vole With A Tick Attached Near Eyeball, H. L. Gunderson Jan 1952

Red-Backed Vole With A Tick Attached Near Eyeball, H. L. Gunderson

University of Nebraska State Museum: Mammalogy Papers

A red-backed vole (Clethrionomys gapperi), with a tick attached to or just under the inner corner of the eyelid at the canthus, was caught in a live trap on July 11, 1961. This is an unusual place of attachment and it is difficult to understand how the tick could have become attached at a point where it could easily be scratched off by either the forefoot or hind foot of the vole.

Notes On Some Trematodes Parasiti,C In Alaskan Canidae, Bert B. Babero, Robert Rausch Jan 1952

Notes On Some Trematodes Parasiti,C In Alaskan Canidae, Bert B. Babero, Robert Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Except for the report of Hadwen (1922) and a few miscellaneous records, little information is available relative to the helminth parasites infecting canine animals in Alaska. During the past two years, 520 autopsies on can ids have been performed in connection with the investigation of animal-borne diseases. The purpose of this note is to record the occurrence of four species of trematodes observed in Alaskan can ids during the course of these studies; one species is apparently reported for the first time from North America. These four parasites are mentioned separately below:

Metorchis albidus (Braun, 1833)

Ackert (1937) recorded this …


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.

Microscopy Of Newly Developed Paper Making Fibers, Richard E. Hathaway Dec 1951

Microscopy Of Newly Developed Paper Making Fibers, Richard E. Hathaway

Paper Engineering Senior Theses

The more important of the newly developed fiberous paper making materials are bleached groundwood, West coast kraft, hardwood kraft, semichemical pulp and cotton linters. The weight factors of these fiberous materials have been determined by several different investigators, but their identification in a paper furnish is very difficult. The weight factors of cotton linters varies with the freeness of the sample, which can be determined by dying the fibers with a mixture of a direct orange and a direct blue bye. Differentiation can be made between bleached and unbleached groundwood with the Loften-Merritt stain. Staining methods cannot be used to …

A Statistical Analysis Of Strength Characteristics Of Handsheets, Edward J. Horvath Dec 1951

A Statistical Analysis Of Strength Characteristics Of Handsheets, Edward J. Horvath

Paper Engineering Senior Theses

A literature survey was made in order to provide an outline of fundamental statistical definitions, formulas and methods which are used by the paper technician. These methods, if properly applied, would furnish valuable information as to the accuracy of test values, significance of differences and merits of various operations.

A demonstration is made of the application of statistical methods to test data obtained from samples of unbleached kraft pulp in the form of wet laps, air-dry pulp and soaked pulp. The analysis was devoted to the study of strength variations, uniformity and duplicability of handsheets produced from the three samples.

Agricultural Productive Capacity 1955 South Dakota, South Dakota Agricultural Experiment Station Nov 1951

Agricultural Productive Capacity 1955 South Dakota, South Dakota Agricultural Experiment Station

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Our agricultural resources have a strategic role to play in the present mobilization effort. Even a partial military mobilization calls for a large increase in food. Our population has increased by 20 million people since 1940. Our civilian per capita food consumption is up 13 percent, our agricultural exports are up 50 percent above the 1935-39 average and food surpluses have largely disappeared. Estimates of our agricultural productive capacity are needed to determine whether such capacity is great enough to meet future needs and to help the nation make wise decisions concerning such vital questions as these: 1. How much …

Use Your Time Efficiently, Isabel Mcgibney Nov 1951

Use Your Time Efficiently, Isabel Mcgibney

SDSU Extension Circulars

There are only 24 hours a day. No matter how hard we try we cannot make more. Time cannot be found, spent or saved it can only be used. Time may be used wisely to gain many desired satisfactions, or it may be used unwisely with few pleasant results. If we want to use time wisely and save effort, we must be willing to admit there is room for improvement. We must also be willing to change from the old "in the rut" way to a new way of doing our job. Can you improve the way of doing your …

Reduced Ascorbic Acid Content Of Potatoes Grown With And Without Straw Mulching And Irrigation In Eastern Nebraska, H. O. Werner, Ruth M. Leverton, Mary R. Gram Nov 1951

Reduced Ascorbic Acid Content Of Potatoes Grown With And Without Straw Mulching And Irrigation In Eastern Nebraska, H. O. Werner, Ruth M. Leverton, Mary R. Gram

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Potatoes harvested from home gardens and in commercial early-producing fields in the Midwest are an important low-cost source of ascorbic acid from late June into September. The major portion of the early commercial crop in Nebraska (harvested mostly in August) is produced with irrigation. Straw or litter mulching is a well established practice in the nonirrigated garden and farm potato patches. The value of these cultural methods for increasing yield is well known, but prior to this study little was known about their influence on the ascorbic acid content of the tubers, or about the persistence of any such influence …
