The Effect Of Certain Chemotherapeutic Substances On Antibody Production, Clifford C. Davis Jr.

Biology ETDs

The purpose of the present study was (1) to compare the production of specific antibodies in normal animals to that seen in similar animals receiving treatment with a given compound during the immunization period; (2) to correlate these responses with the over-all physiologic response of the animal to the compound; and (3) attempt to account for any variations from the normal by these animals.

Stem Anatomy Of Twelve Forbs Of The Family Compositae Growing Near Hays, Kansas, Cheng Lin

Master's Theses

The importance of forbs to the livestock diet seems to come from their high percentage of calcium and phosphorus (Runyon, 1947). Furthermore, they also contain a higher amount of moisture (Savage and Heller, 1947) which makes them more succulent and therefore more palatable than the grasses during drought. This condition of greater succulence is due in part at least to _the more deeply penetrating roots of the forbs (Albertson, 1937). Observations also have indicated the possibility of a considerable amount of latex, oils and resins in the green forb plants. Because of the importance of these plants it was thought …

Effect Of Storage Temperatures On Triumph Seed Potatoes Used For The Early Crop In The South And In Central Nebraska, H. O. Werner

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

During the decade 1931-1940 it became increasingly apparent that some factor (or factors) besides disease was responsible for much of the variation in yields produced by lots of certified seed potatoes planted in commercial fields and comparative trial plots in the South during midwinter. This bulletin reports investigations into the method of storing western Nebraska seed potatoes as a means of improving the production of the early crop of Triumphs in the Gulf Coast States.

The Structure And Reproduction Of Corn, T. A. Kiesselbach

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The primary purpose of this paper is to summarize investigations concerning the structure and reproduction of the corn plant (Zea mays L.). Because of wide interest in the reproductive process in connection with breeding and genetic studies the floral development, fertilization, and embryology are especially stressed. The morphology and development of the vegetative organs is also included. The botanical relationship, origin, genetics and breeding of corn are briefly considered.

Potato Ring Rot, L.T. Richardson

Agricultural Experiment Station Plant Pathology Pamphlets (1942-1962)

Every potato grower should be on guard against the destructive disease known as bacterial ring rot of potatoes, whether the potatoes are grown for seed or for table purposes. If even a trace of the disease was found in your crop this year, every effort should be made to eliminate it. If no ring rot appeared this year, precautions should be taken to prevent its introduction to the farm through seed, sacks, machinery, hauling equipment, or other means. It does not pay to take a chance with bacterial ring rot.

Liquid Loss From Glass Jars Processed In The Pressure Cooker, Arnold E. Baragar

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Home canners and extension home economists have inquired frequently why much liquid is sometimes lost from glass jars of food processed in the pressure cooker. At an extension service Home Canning Research Conference held at Kansas City, December, 1946, state extension agents requested research on this home canning problem, because no published reports were available. This bulletin is a report of experiments with glass jars processed in a pressure cooker to determine (1) conditions that allow much liquid to be expelled from jars, (2) conditions that reduce liquid loss to a negligible amount, and (3) the physical conditions involved in …

Observations Of The Life Cycle And Larval Development Of Paruterina Candelabraria (Goeze, 1782) (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Paruterina candelabraria (Goeze, 1782) is parasitic in owls in Europe and North America, and appears to be the most frequently encountered cestode occurring in strigiform birds (Wolffhugel, 1900; Rausch, 1948). It is the purpose of this paper to present observations on the larval development and life cycle of P. candelabraria. Apparently nothing is known concerning the life cycles of cestodes of the genus Paruterina Fuhrmann, 1906, most of which occur in passeriform birds.

Botanical Records Of Field Work In The Southern United States In 1945 And 1947, Rogers Mcvaugh

Field and Laboratory

For about three months in 1945, and for a similar period in 1947, I was able to carry on field-work in systematic botany in the southern United States, chiefly in Texas, but with some attention to neighboring states. The work in 1945 was a joint project of Southern Methodist University and the Bureau of Plant Industry, U.S. Department of Agriculture; I was delegated by the Bureau to join field-parties sent out by the University. The work in 1947 was undertaken by the University of Michigan, with the cooperation of Southern Methodist University and of the Arnold Arboretum, Harvard University.

The Texas Species Of Conyza (Compositae), Lloyd H. Shinners

Field and Laboratory

The transfer of those species of Erigeron sometimes segregated under Leptilon to the widespread tropical genus Conyza by Dr. Arthur Cronquist (1943) brings together five annual weeds of Texas which are obviously closely allied. They may be distinguished by the following key. Specimens mentioned in the discussion are in the Herbarium of Southern Methodist University.

Nomenclature Of Texas Varieties Of Descurainia Pinnata (Cruciferae), Lloyd H. Shinners

Field and Laboratory

In LeRoy E. Detling's Revision of the North American species of Descurainia (Amer. Midi. Nat. 22: 481-520, 1939), the barely distinguishable races of D. pinnata are termed subspecies. The following are credited to Texas, listed here with the proper name as variety. Since a proposal to make mandatory the repetition of the specific epithet for the typical variety of a species has been approved by members of the American Society of Plant Taxonomists, and by a preliminary symposium at Utrecht considering proposals to be submitted to the next International Botanical Congress (see Brittonia 7: 16-17, 1949), no name is proposed …
