The Stomatal Behvior Of Begonias And Its Relationship To Infection By Xanthomonas Begoniae, Eugene David Kitzke

Bachelors’ Theses

A leaf spot disease of begonias caused by a bacterium has been under observation and study at Marquette University for nearly a year. It brings up many interesting questions which need to be an­swered before the investigators can fully evaluate and determine correctly the relationships of this organism to the Begoniaceae. One of the questions, which has come up, was the problem of the mode of entrance. It is the purpose of this paper to deter­ mine the relation of the stomata to infection.

Histological Study Of The Small Intestine Of The Common Green Snake, Thamnophis Sirtalis, Robert George Stineman

Bachelors’ Theses

Although much work has been done histologically with the vertebrates, very little seems to have been done on the intestinal tract of the reptile. This is especially true of the snakes, despite the abundant sources of material. Reptiles are one of the first classes of vertebrates in which there is a distinction made between small and large intestine. Histology textbooks devote only a few lines to the histology of the reptilian small intestine. For this reason it seems that it would be worthwhile to make a detailed study of that portion of the intestinal tract immediately distal to the duodenum …

The Histology Of The Digestive Tract Of The Common Green Snake, Thamnophis Sirtalis 3. Esophagus, Janice Jean Mcfarlane

Bachelors’ Theses

This is the third in a series of investigations of the comparative histology of the digestive tract of Thamnophis sirtalis, the common green snake. Comparatively little recent work of this nature upon any of the class Reptilia, and especially upon the order Ophidia, seems to have been undertaken. Kendall(1940) makes no mention of Ophidia, but discusses briefly the digestive system of the lizard, limiting his treatment of the esophagus to a few lines. Cole (1941) has an equally short and general discussion of the digestive system of Thamnophis sirtalis, again devoting but a brief space to his discussion of the …

Atypical Conditions Of The Inferior Vena Cava, Mary F. Reagan

Bachelors’ Theses

Extensive dissection of various mammalian forms, expecially of man, the rabbit, and the cat has led to a recognition of a certain vascular pattern of the inferior vena cava which is typical for the group, It occurs so consistently that the occasional specimens which differ from it are of interest because of both their ontogenetic and phylogenetic significance.

The Feulgen Reaction Applied To Various Platyhelminthes And Small Ascarid Worms Mounted In Toto In Balsam Oil, Louise R. Russort

Bachelors’ Theses

The problem involved in this experiment was the application of the Feulgen Reaction to a number of flatworms and small ascarid worms, in an attempt to ascertain whether or not a practical staining technique, (showing clear differentiation of nuclear material, etc., from the surrounding cuticle and cytoplasm) -- may be developed, by staining and mounting them in toto. The Feulgen Reaction was used in this experiment, not as a specific indicator for thymonucleic acid, but rather as a cytological stain. Some attention will be focused upon the reaction's specificity, however, in the following discussion of the development of the reaction …

Some Technique Methods For Preparing Slides Of The Paramecium, Irene Padley

Bachelors’ Theses

Du Jardin (1835) was probably the first to recognize in protozoa, living substance. To this substance, he applied the word sarcode. In 1861, Max Schultze expressed the idea that sarcode and protoplasm are the same thing.

Bulletin No. 318 - An Economic Analysis Of Turkey Production In Utah, Dee A. Broadbent, W. Preston Thomas, George T. Blanch

UAES Bulletins

The production of turkeys for market by farmers in Utah has increased rapidly since 1935, and in 1944 was the highest in the history of the state. Although turkeys are produced on a relatively few farms , the enterprise is an important source of the state's agricultural income. In 1942 and 1943, the cash income from sales of turkeys was almost six million dollars or equivalent to 5 percent of the total cash income of the state.

In addition to the sale of turkeys, this new enterprise supports, fully or in part, other industries of the state. The processing plants, …

Bulletin No. 319 - Cherry Rootstocks, Francis M. Coe

UAES Bulletins

This paper reviews the history and status of the cherry rootstocks problem in Utah and the United States and reports 14 years' results from a sweet cherry rootstocks test orchard on open porous soil at Farmington, Utah.

Although a majority of authorities favor or recommend the mazzard root for sweet cherries, the mahaleb is also widely used and preferred by many nurserymen and growers. Many authorities condemn mahaleb stocks as being dwarfing and short lived. Two orchard tests on heavy soils in the Atlantic states decisively favor mazzard.

In the Utah test orchard, the trees on mahaleb proved to be …

The North American Species Of Smilacina, Desma H. Galway

Theses and Dissertations

This paper is the result of a taxonomic study of the species of the genus Smilacina occurring naturally in North America north of Mexico. In the past it has been difficult to make satisfactory determinations of members of this genus from existing manuals, especially among western forms. West of the great plains the great diversity in environmental conditions has given rise to a diversity in form of the species that are widely distributed. Many of these forms have been given specific or varietal names recently, and as no comprehensive work on the genus has been done since most of these …

Range Land Of America And Some Research On Its Management, Laurence A. Stoddart

Faculty Honor Lectures

Although grazing of livestock has been a practice and a profession of man almost from his beginning only recently has range management reached anything approaching a pre~ cise science. Although ' trials and errors over the years brought to light much practical methodology for assuring high production from grazing land, still it remained for the plant physiologist and ecologist to find the whys and wherefores, and to advance new methods and new thoughts which promise to increase productivity still further and at the same time maintain the great range resource.

The peculiar land situation that marked America in her forma~ …

Charcoal Rot Of Corn And Sorghum, J. E. Livingston

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In Nebraska, the charcoal rot caused considerable damage to the 1940 grain sorghum crop in the south central counties, and the following year it caused serious lodging and reduction of yield in both corn and sorghum in all sections of the state. Field observations indicated that some varieties of sorghum were damaged less than others; thus it appeared desirable to test thoroughly all varieties to determine whether any were sufficiently resistant to be recommended for field planting or to be used in a breeding program. It seemed desirable to study the influence of soil environment on infection and the development …

Studies On The Riboflavin Content Of Cheese, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The riboflavin concentrations of twenty-seven kinds of cheeses and cheese spreads were determined by feeding these products to rats whose body stores of riboflavin had been depleted by being fed a riboflavin-deficient diet. Fifteen experiments were made in which 1,223 rats were used. The results obtained varied from 13.5 to 1.2 micrograms of riboflavin per gram of cheese (or spread). The samples of Goat, Velveeta, Mel-0-Pure, and Liederkranz had the highest concentrations of riboflavin while the samples of Cream and Pimento Cream had the lowest concentrations.

Bulletin No. 317 - Range Lands Of Utah County And Their Utilization, L. A. Stoddart

UAES Bulletins

Utah County, comprising about 1,394,760 acres, lies in the north central part of Utah immediately west of the precipitous Wasatch Mountains. These mountains, which occupy about the eastern half of the county, vary in elevation from 4,700 feet at the bench lands to 9,000 and 10,000 feet. Extreme elevations of 12,000 feet are found on the highest peaks. The western half of the county, although broken by small mountain ranges, is much more level, lower in elevation, and more arid. Whereas the mountainous eastern parts of the county are marked by higher precipitation and, consequently by relatively dense vegetation, mostly …

Bulletin No. 316 - Marketing Fruits And Vegetables In Utah, W. Preston Thomas, George T. Blanch

UAES Bulletins

During the period from 1920 to 1941 the fruit industry in Utah and other areas or the west went through a period of adjustment. Previous to and during World War I, growers received high prices for fruit which resulted in increased production. However, following the sudden drop in prices of 1920, fruit growers had a hard time to market the large tonnage produced. Returns were low. During this period keen competition for the sale of fruits developed between individual growers and various producing areas. Although the problems of adjustment were severe in most fruit areas of the west, the marketing …

Electric Chick Brooding Studies, F. D. Yung, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Perhaps one of the most valuable lessons to be learned from a study of chick brooding is that good results can often be obtained in more ways than one. In carrying on work with electric brooders at the Nebraska Agricultural Experiment Station, special attention has been given to such factors as insulation and to other details of design which effect economy of operation and ease of construction. Low cost rather than "cheapness" has been the ideal. The work has been cooperative between the Agricultural Engineering Department and the Poultry Husbandry Department of the University of Nebraska.

Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson

Publications (WR)

Whether the tremendously increased population acquired by Las Vegas in the years 1940 to 1942 will be retained cannot at present be foretold. However, the valley will undoubtedly be expected to support a considerably larger population than it did at any time prior to 1940, and continually increasing demands on the water supply for innumerable pcacetimc activities must be anticipated. Therefore, a sound evaluation of tho ground water resources of Las Vegas Valley is directly in line with the other wisely progressive planning programs which are now operating or are taking shape in the valley as well as in the …

Poultry Progress: Our Egg Marketing Job, F. E. Mussehl, H. C. Filley

Nebraska Agricultural Experiment Station: Historical Circulars

Eggs are one of the products which Nebraska farm families exchange for the necessities and comforts of life. Although values are measured in dollars and cents, the interest of the producers centers in the amount of useful goods and services that the eggs will buy rather than in the price per dozen or per case. Farmers are interested in a fair exchange value because they wish better homes, better schools, better churches, and better communities in general. In the typical Nebraska community, not only farmers but physicians, merchants, mechanics and school teachers are dependent for their income, either directly or …

The Effect Of Adrenaline Injection On Glycogenolysis And Glycogenesis In Rat Livers, Virginia Mary Zingsheim

Bachelors’ Theses

Present day knowledge concerning the liver is derived from many sources and the accumulation of many methods of investigation. Sugar, which is needed by the body for energy, is stored in the liver as glycogen. Claude Bernard (26), an eminent physiologist, was the first to suspect that carbohydrates were stored in the liver. Faulty glycogen synthesis and hydrolysis results in one of our most widespread diseases, diabetes. Thus, many biochemists and physiologists have tried to find the mechanism of the process, and the primary and secondary facts which affect glycogenesis and glycogenolysis. Although the chemical secretions and hormones of such …

Making Permanent Mounts Of Fern Gametophytes, Gail Seeraphine Barczak

Bachelors’ Theses

One of the botanists first to grow fern gametophytes from spores whicch were sown on moist clay was Farlow (1874), a student of the famous botanist, DeBary, professor of Botany at the University of Strassburg in Germany. Farlow sowed the spores of Ptteris cretica var. albo-lineata on moist clay placed into small flower pots. Watering was accomplished from the top. There was no sterilization of the culture medium. The gametophytes of this fern were also grown under the same conditions by DeBary (1878). Steil (1919a) grew the prothalli of Ptteris sulcata and Ptteris cretica var. albo-lineata in the same manner …

Nyssa Woods Of The Pacific-Northwest Tertiary, George F. Beck

All Faculty Scholarship for the College of the Sciences

The nyssa gums are one of the modern genera of trees most certainly present among the petrified woods and forests of the Pacific Northwest. Almost every collection from the mid-Tertiary of this region contains a few specimens of typical tupelo or sour gum. These are fine-grained woods which to the unaided eye may be mistaken for conifers.

Yields And Consumption Of Forage In Three Pasture-Types: An Ecological Analysis, R. W. Darland, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Native pastures in eastern Nebraska and adjacent states have undergone profound changes as a result of drought. Bluestems (Andropogon) and associated grasses have been thinned and weakened, although recovery has been marked since 1941. In many pastures they were replaced by western wheat grass (Agropyron smithii) or other invading species. In nearly all, wheat grass now occurs in considerable abundance. Kentucky bluegrass (Paa pratensis), into which many overgrazed native pastures had degenerated, was almost completely killed by the drought, or greatly damaged as in western Iowa. Despite these widespread changes, few studies have been made on the relative yields, preferences …
