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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 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 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 …

The Occurrence Of Contracaecum Travassosi (Nematoda) In North America [Research Notes], Banner Bill Morgan, Robert L. Rausch, Everett Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Seven specimens of a nematode (five males and two females) of the genus Contracaecum were collected from the ventriculus of Pandion haliaetus carolinensis (Gmelin) (osprey) captured at Greenville, Ohio. After a comparison with C. travassosi described by Gutierrez (1943. Sobre la morfología de una nueva especie de "Contracaecum" (Nematoda: Ascaroidea) Rev. Brasil. Biol. 3: 159-172) from the cormorant (Phalacrocorax albiventer) collected at the San Jose light-house, Territory of Chubut, Argentina, our material has been assigned to that species. So far as the writers have been able to determine, this is the first record of the species …

A Filter Paper "Chromatopile", Herschel Mitchell, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

The application of one- and two-dimensional paper chromatography to the separation of small amounts of many kinds of compounds has become a well-established and useful technique (1, 2, 3, 5, 6). In general these methods do not handle sufficiently large quantities of materials for isolation and chemical identification. Large columns of starch and other materials have been used satisfactorily for handling larger quantities of mixtures (4). Starch columns proved to be unsatisfactory, how- ever, for isolation of certain substances under investigation in this laboratory. As a consequence, a new and simple apparatus and technique have been developed, using …

A Study Of The Effects Of An Estrogenic Complex On Bacillus Subtilus, Roger S. Wotkyns

Biology ETDs

In an effort to understand malignancies, a number of studies have been made on the quantitative aspects of the effects of synthetic carcinogenic hydrocarbons on microorganisms. The molecular similarities of these synthetic carcinogens and natural products such as the estrogens, the androgens, cholic acid, vitamin D and others have stimulated a great deal of interest in investigation of the possible carcinogenic nature of these natural products.

The European Corn Borer, Gerald B. Spawn

Agricultural Experiment Station Entomology Pamphlets (1940-1952)

The European corn borer was first recorded from South Dakota i n the summer of 1946. At that time Hr. H. C. Severin and the author found borers in corn in Union and Lincoln and Minnehaha counties. Less than half of one percent of the stalks in the fields were infested at that time. During the summer of 1948 the infestation had spread over most of the corn producing area of our state. By the fall of that year 36 counties were known to be infested . Several fields in the southeastern part of the state had 100 per cent …

Quantitative Study Of Root Systems In Different Soil Types, J. E. Weaver, R. W. Darland

Department of Agronomy and Horticulture: Faculty Publications

Study of soil-root relations of various crop plants and range grasses has lagged far behind the pressing need for an understanding of these relationships. Little progress in devising new methods for such study, at least methods that have been widely used in the field, has been made since the extensive researches by the direct method, using trench and hand pick, employed by Weaver (1, 2) during the period 1919 to 1926. This lack of a quantitative approach to comparative root studies in various soil types has undoubtedly been a chief reason for the dearth of more definite information on this …
