A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum (1924–2023)
Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.
Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.
Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.
Bulletin of the University of Nebraska State Museum (1924–2023)
Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.
Frost Injury Of Wheat, S C. Chambers
Frost Injury Of Wheat, S C. Chambers
Journal of the Department of Agriculture, Western Australia, Series 4
Late spring frosts commonly reduce yields and affect the quality of grain in many wheat crops- especially throughout the southern, eastern and north-eastern districts.

Growth Study Of Young Gizzard Shad, George Pahl, Gordon Willfahrt
Growth Study Of Young Gizzard Shad, George Pahl, Gordon Willfahrt
Journal of the Minnesota Academy of Science
This investigation was part of a general study aimed at shedding light upon the role of the gizzard shad (Dorosoma cepedianum) as a forage fish of certain game fish species. Recent changes in the populations of such game fish species as the walleye ( Stizastedion vitreum), northern pike ( Esox lucius) , and largemouth bass (Micropterus salmoides) in the upper Mississippi River suggest that the gizzard shad population might have an important bearing on the present situation. The purpose of this investigation was to study the growth rates of the gizzard shad in the Upper Mississippi River during their first …
Farming Without Fallow, H M. Fisher
Farming Without Fallow, H M. Fisher
Journal of the Department of Agriculture, Western Australia, Series 4
UNDER the more intensive cropping rotations common in the early development of the cereal areas of Western Australia bare fallowing was a basic technique in cereal production.
By ploughing the land in July or August and keeping it bare of vegetation for nine or ten months, either by grazing or cultivation, a substantial beneficial effect on the subsequent crop could be expected.
Pigs On The Dairy Farm : Cutting Costs To Meet Low Prices, R A. Bettenay
Pigs On The Dairy Farm : Cutting Costs To Meet Low Prices, R A. Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
As all dairy farmers know, the market prices of pigs tends to fluctuate, depending on supply and demand, in a manner which is very hard to predict.
At a time when prices are low there are several things which the dairy farmer can do to continue operating, although at a reduced margin.

Bare Patch And Poor Emergence Of Cereals. 3. Crusting Of The Soil Surface, S C. Chambers
Bare Patch And Poor Emergence Of Cereals. 3. Crusting Of The Soil Surface, S C. Chambers
Journal of the Department of Agriculture, Western Australia, Series 4
In some seasons extensive bare patches occur in cereal crops sown on the heavier wheat belt soils.
Experimental results from Beverley indicate that the poor emergence in some of these plantings may be due to crusting of the soil surface.
Working the surface with light harrows may destroy the crust and improve emergence.

BECAUSE of the scattered distribution of light lands of the agricultural areas of Western Australia among the better soils, and their large total area, it is not surprising that attempts to develop these unattractive soils for agriculture started many years ago.
Relative Growth In Some Antarctic Pycnogonida, William Granow Fry
Relative Growth In Some Antarctic Pycnogonida, William Granow Fry
University of the Pacific Theses and Dissertations
Work on the systematics of a large collection of Antarctic Pycnogohida has revealed very forcibly the limitations of existing systems of classification of this group. In an attempt to rectify some of these shortcomings for a monograph on the pycnogonid fauna of the Ross Sea area, the author has been led to seek new characters and character states which will be useful in taxonomy.
Virtually nothing is known of pycnogonid behaviour and ecology, and it seems unlikely that additional knowledge in these fields will be forthcoming in the near future. Our knowledge of pycnogonid comparative anatomy and histology is also …

Shellfish Resources Of Washington, Robert Grant Levens
Shellfish Resources Of Washington, Robert Grant Levens
Graduate Student Research Papers
This paper will explore the salt water shellfish resources of Washington State. Particular emphasis will be placed upon the Pacific and Olympia Oysters, the Dungeness Crab, the research being done at Quilcene, and the lesser varieties of shellfish, including shrimp and the hardshell species of clams. The latter includes the littleneck, butter, Manila, and geoduc clams. A major emphasis will be the commercial importance of the shellfish, but the sportsman and the expanding role of Washington as a summer recreation area will not be overlooked.
Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton
Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton
Masters Theses
Chapter I
Introduction
In discussing the basis for teaching high school biology, Van Deventer1 states, "...the present typical course in high school biology serves adequately neither the terminal student nor the college entrance student." He holds that today's courses present watered-down versions of college courses to the student before the intelligence of the student has matured enough to grasp such subject matter. As a result there is very little carry-over value from such courses, and the students may even develop a dislike for biology. This study constitutes an effort to understand these problems and to devise ways of solving …
The Utilization Of Hydrogenated Tall Oil In Paper Furnishes, Thomas W. Asmus
The Utilization Of Hydrogenated Tall Oil In Paper Furnishes, Thomas W. Asmus
Paper Engineering Senior Theses
A literature survey is presented concerning the properties of tall oil, the theory of catalysis, and catalytic hydrogenation applied to tall oil. It is the purpose of the experimental work to prepare a material from tall oil by hydrogenation which will lend itself more useful as a sizing agent for certain low grades of paper.
The experimental results indicated that by hydrogenating tall oil soap, a whiter, less oily material is obtainable. Handsheets were prepared using this hydrogenated material, the starting material, and rosin size as sizing agents. It was found that the handsheets sized with the hydrogenated material had …

Application Of Knowledge Of Medications By Senior Students In A Selected School Of Nursing, Patricia H. Okimi
Loma Linda University Electronic Theses, Dissertations & Projects
The problem arose from the need to study the present method of pharmacology instruction in a selected school of nursing. "How much knowledge of medications do selected senior students have, and how do they apply their knowledge in the administration of medications?"
For this study, the normative survey approach was used as the method of research. Eleven senior students of nursing engaged in the administration of medications, as team leaders, were observed and questioned on two different occasions during one quarter of their school year. The tool of research used to collect data was an observation code sheet developed for …

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams
The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).

Distribution Of Army Cutworm Larvae In Wheat And Barley Fields, K. P. Pruess
Distribution Of Army Cutworm Larvae In Wheat And Barley Fields, K. P. Pruess
Department of Entomology: Faculty Publications
Populations of the army cutworm, Chorizagrotis auxiliaris (Grote), tended to be higher in winter barley than winter wheat planted side by side in the same field. Highest populations occurred in barley within 30 feet of the adjoining wheat. Distribution of larvae in linear 1-foot samples agreed closely with the Poisson. Practical application of these results are discussed.

Bluebush Seed : Cleaning, Drying And Storing, C V. Malcolm
Bluebush Seed : Cleaning, Drying And Storing, C V. Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
BLUEBUSH (Kochia brevifolia) is a perennial plant which occurs naturally in Western Australia.
In the past it has attracted little attention, but in recent years it has created interest as a highly nutritious and salt tolerant plant well adapted to certain salt affected soils in the wheatbelt.
A previous article (Bulletin No. 2630) by Smith and Malcolm drew attention to its use. One of the problems in establishing bluebush is to obtain seed supplies.
