Pigment Migration In The Eye Of Forbesichthys Papilliferus, Harld Welborn

Masters Theses & Specialist Projects

Previous studies conducted in these laboratories showed the pigment in the eye of Forbesichthys papilliferus, when exposed to light, migrated from the stratum pigmenti into the layer of rods and cones. It was thought advisable to investigate this matter further. The following lines of investigation were conducted, viz:

1. to determine the rate at which the pigment migrates from the stratum pimenti into the layer of rods and cones when exposed to sunlight;
2. to determine the rate at which the pigment migrates from the stratum pigmenti into the layer of rods and cones when exposed to artificial light; and
3. to determine …

The Flora Of The Tasco Lake Region, Sheridan County, Kansas, Raymond W. Darland

Master's Theses or Doctor of Nursing Practice

It has been customary in writing theses dealing with taxonomic problems to collect data from an entire county. Having had occasion to collect botanical specimens from the Tasco Lake for work in biology at the Sheridan High School, the wealth of plant life to be found here became apparent. The area ranges from xerophytic forms on the uplands to the hydrophytic forms in the lake and marshes. Many of the latter have never been reported from Western Kansas. Collections in preserving fluid were made of the water forms found and specimens of the landforms were mounted on regulation-sized sheets properly …

The Effect Of Variation In The Calcium-To-Phosphorus Ratio On The Utilization Of Nitrogen, Calcium, And Phosphorus By The Growing Chick, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. Three groups totaling 123 chicks were fed accurately known amounts of rations containing 0.9, 1.5, and 2.3 per cent of calcium with liberal provision of the antirachitic factor so that conditions for assimilation and deposition were favorable. 2. By means of the comparative slaughter test the retention of ingested nitrogen was found to be about 37 per cent, and that of phosphorus about 28 per cent in the three lots. 3. With 0.9 per cent calcium in the ration, 35 per cent of that ingested was retained; at a level of 1.5 per cent calcium, 24 per cent was …

Spermatogenesis Of The Albino Rat (Nus Norvegicus Albus), Norman A. Frankenstein

Bachelors’ Theses

This thesis deals with the inquiry opened by the fundamental discovery that the gamete nuclei, and hence, the two parents from which they are respectively derived, con­ tribute each a haploid or single group of chromosomes to the fertilized egg. Each act of fertilization doubles the gametic number of chromosomes; yet the number of characteristic of the species remains constant from generation to generation. Somewhere in the life cycle, accordingly, the diploid or somatic number must be reduced by one-half to the haploid or gametic number. The first explanation was that reduction took place by some process of degeneration or …

Histological Study Of The Structure Of The Testis Of Rana Pipiens, John L. Friedl

Bachelors’ Theses

All the living organisms, be they plant or animal, act as a unit which implies that the various anatomical and physiological systems are coordinated either for the benefit of the Individual itself or for the maintenance of the spe­cies. For convenience sake, the individual is divided into a digestive,. respiratory, circulatory, nervous, muscular, and skeletal systems; but there is one system which although of some value to the individual is primarily adapted for the production of other individuals, and this is the reproductive system.

A Century Of Scientific Exploration In Texas Part 1: 1820-1880, S. W. Geiser

Field and Laboratory

Science evolves and is perfected by the patient and criti cal labors of generations of investigators; and scientific progress is marked by an unending series of publications. To this fact, indeed, is due the perennial interest of the History of Science…. Texas has an almost unique place in the history of scientific exploration. This is probably owing to a number of singular coincidences.

The Anatomy Of The Oyster, M.J. Rohlinger

Bachelors’ Theses

The phylum Mollusca manifests the following characteristics: bilateral symmetry; three primary germ layers; free-living and sessile; marine and fresh-water; a shell modified to form either a bivalve or a univalve which gives an appearance of segmentation due to rings of growth or arrangement of certain parts of the shell as is seen in the class Amphineura, this is only apparent metamerism because the Mollusca are considered to be unsegmented animals; a coelom poorly developed; a foot; a mantle cavity; well developed digestive, circulatory, excretory, and reproductive systems. When one inspects a Chiton, an oyster, a snail, an octopus, or a …

Topographical Anatomy Of Ostrea Virginica, Harry J. Barnett

Bachelors’ Theses

The oyster is important for at least three reasons. First, it is important to the zoologist; second, it is a food which has developed million dollar enterprises; and third, the oyster is a domestic resource for the pearl and its allied industries. The oyster is a bivalve Mollusk, having symmetry in the larval stage but losing it in the adult stage. It has one large adductor muscle, somewhat posterior from the ligament which holds both valves together. The left valve forms a deeper pit than the right one as it is in the left valve that the oyster lies. It …

The Effect Of Pregnancy And Parturition On The Weight Of Dairy Cows, R. F. Morgan, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A study was made of the effect of pregnancy and parturition upon the weight cycle of dairy cows of the Ayrshire, Guernsey, Holstein, and Jersey breeds according to gestation periods from data accumulated from records for the period 1922 to 1934 of the dairy herd of the Dairy Husbandry Department of the University of Nebraska. The weights of the cows were obtained from three consecutive weighings made at the middle of each month and daily weighings beginning at the 265th day of pregnancy and continuing for 30 days after calving. A total of 656 separate gestation periods were tabulated according …

Bulletin No. 265 - Phosphorus Supplements Improve Sugar-Beet By-Product Rations For Cattle, E. J. Maynard, J. E. Greaves, H. H. Smith

UAES Bulletins

In sugar-beet producing areas of the Intermountain West and Pacific Coast beet by-products constitute a most economical source of feed for fattening livestock.

In Utah there are available each year some 144,000 tons of wet beet pulp and some 20,000 tons of beet molasses; in addition, about 6500 tons of dried molasses beet pulp are available in the form of meal or pellets.

Practically all of this livestock feed supply, with a nutritive value equivalent to approximately 41,000 tons of corn or barley, has been fed, together with alfalfa hay, to cattle or sheep for maintenance or in the production …

Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

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

There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.

Factors Controlling Initial Establishment Of Western White Pine And Associated Species, Irvine T. Haig

Yale School of the Environment Bulletin Series

The principal object of the study was to determine the roles played by important physical factors of site, chiefly as these vary with overhead shade and hence are within the control of the silviculturist at the time of logging. No special effort was made to study the effect of biotic agents under natural conditions. Indeed, in order to insure as large a sample of seedlings as possible on which to follow losses caused by physical factors, biotic agents were discouraged wherever feasible. But as records of all mortality losses were kept by cause, some information was collected on the activity …

Bulletin No. 263 - Relative Produciton Of Feed Grain From Spring-Grown Cereals In Utah, R. W. Woodward, D. C. Tingey

UAES Bulletins

Nearly one-third of the cropped acreage of Utah is devoted to cereals. Except for wheat, most of these crops are fed locally. In addition to this, an average of over a million bushels of corn, barley, and oats is shipped into the state each year to be used in various livestock and poultry industries.

The purpose of this publication is to show the comparative amount of feed produced by the different crops--wheat, oats, barley, and corn--under similar conditions as determined for the specified four years by acre-yields obtained in various agricultural regions of the state. One should bear clearly in …

Bulletin No. 259 - Drainage Of Land Overlying An Artesian Groudwater Reservoir: Final Report, O. W. Israelsen, W. W. Mclaughlin

UAES Bulletins

This bulletin constitutes a final report of some phases of cooperative drainage studies in Cache Valley, Utah. The drainage problem in Cache Valley is typical, in many respects, of drainage problems in other irrigated valleys of Utah and the West in general. Application of the principles indicated by the problems will doubtless add materially to the productivity of the land in the several communities concerned and will also contribute to the advancement of public welfare in the general improvement of health, economic, and social conditions. Alkali and water-logging affecting large areas are causes not only of low productivity of the …

Relative Efficiency Of Roots And Tops Of Plants In Protecting The Soil From Erosion, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Plant cover, soil and topography are the major factors concerned in the problem of erosion. During the earlier studies, conducted largely by engineers, chief emphasis was placed upon topography. Following extensive work by pedologists, it is now generally conceded that type of soil is an equally important factor. Intensive studies on the effect of plant cover reveal the extremely important role played by plants in holding the soil against the forces of erosion. In this preliminary account of the relative effectiveness of roots as compared to tops in holding the soil in place, the results are based on extensive experiments …

Role Of Fire In Pasture Management, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

The practice of burning grass is an old one. It was extensively used by the Indians to attract game animals in early spring and to facilitate hunting. It is also highly probable that a large portion of the prairie was burned periodically during very dry years from natural causes

The Utilization Of Nitrogen, Calcium, And Phosphorus By The Growing Chick, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The nitrogen, calcium, and phosphorus content of 127 newly hatched chicks was determined. 2. Thirty newly hatched chicks were fed accurately known amounts of a good chick mash for 60 days. At the end of the period nitrogen, calcium, phosphorus, and fat were determined for each chick. 3. By means of the comparative slaughter test the retention of nitrogen was found to be 37.8 per cent, calcium 43.4 per cent, and phosphorus 27.3 per cent of the respective elements fed. 4. The average gain in live weight per gram of nitrogen fed was 12.0 grams. 5. The rate of …
