The Stomatal Behvior Of Begonias And Its Relationship To Infection By Xanthomonas Begoniae, Eugene David Kitzke Jun 1945

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.


Some Technique Methods For Preparing Slides Of The Paramecium, Irene Padley Jun 1945

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.


Range Land Of America And Some Research On Its Management, Laurence A. Stoddart Apr 1945

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~ …


Bulletin No. 317 - Range Lands Of Utah County And Their Utilization, L. A. Stoddart Mar 1945

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 …


Electric Chick Brooding Studies, F. D. Yung, F. E. Mussehl Mar 1945

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.


The Effect Of Adrenaline Injection On Glycogenolysis And Glycogenesis In Rat Livers, Virginia Mary Zingsheim Feb 1945

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 Feb 1945

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 …


Yields And Consumption Of Forage In Three Pasture-Types: An Ecological Analysis, R. W. Darland, J. E. Weaver Feb 1945

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 …

The Development Of Bone In The Chick Embryo, Helen M. Koelsch Oct 1944

The Development Of Bone In The Chick Embryo, Helen M. Koelsch

Bachelors’ Theses

The day by day development of the bone in the chicken embryo as determined by the fixing and staining of embryos for each twenty-four hour growth period during the time of greatest skeletal development, is the subject of this paper. The stage in the embryological history of the chick during which the most important phases of bone development occur was determined to be the period between the seventh and the sixteenth days of incubation. It is therefore the purpose of this investigation to give an account of the growth and development of the bones of the ordinary domestic fowl as …

Bulletin No. 314 - Gains Made By Cattle On Summer Range In Northern Utah, L. A. Stoddart Jun 1944

Bulletin No. 314 - Gains Made By Cattle On Summer Range In Northern Utah, L. A. Stoddart

UAES Bulletins

The Utah Agricultural Experiment Station, in 1934, began experimental studies on the grazing of beef steers on mountainous summer range lands. Although the direct purpose of this work was to find whether supplementing phosphorus in the diet of grazing steers would increase their gains, many incidental observations proved of great interest. Among the most significant were the distribution and extent of weight gains through the summer grazing season and the effects of various factors such as weather upon the gains, causing them to vary greatly from year to year.

Field and Laboratory

The most articulate explorer of East Texas oil fields ­ the man whose work appears to have caused the incorpora tion of a number of oil companies in that section - was a Kentuckian, Benjamin Taylor Kavanaugh (1805-88).


Notes On The Trematode Subfamily Loimoinae (Monogenea), With A Description Of A New Genus, Harold W. Manter, Waldo L. Schmitt Mar 1944

Notes On The Trematode Subfamily Loimoinae (Monogenea), With A Description Of A New Genus, Harold W. Manter, Waldo L. Schmitt

Harold W. Manter Laboratory of Parasitology: Library Materials

The subfamily Loimoinae was named by Price (1936) for a peculiar monogenetic trematode, Loimos salpinggoides MacCal lum, 1917, from the gills of a dusky shark, Carcharias obscurus (Lesueur), at Woods Hole, Massachusetts, USA. Price (1938) redescribed this trematode, correcting several errors made by MacCallum. Manter (1938) described Tricotyle scoliodoni from a shark, Scoliodon terrae-novae (Richardson), from Beaufort, North Carolina, USA. He noted some similarities between Tricotyle and Loimos. The redescription of Loimos by Price increased these similarities.

The Nymph Of Enallagma Basidens Calvert (Odonata, Coenagrionidae), Alice Ferguson

Field and Laboratory

The species Enallagma basidens Calvert, one of the abundant Coenagrionid Odonates of Dallas County, Texas, is widely distributed in the streams and ponds of the county. As its nymph has never, so far as I can discover, been described, I take occasion to do so in this brief note.
