Phytotoxic Substances From Soil Microorganisms And Crop Residues, T.M. Mccalla, F.A. Haskins Jun 1964

Phytotoxic Substances From Soil Microorganisms And Crop Residues, T.M. Mccalla, F.A. Haskins

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The role of organic matter in the growth of plants has been a subject of much investigation and controversy since the sixteenth century. During the early era, decomposition of plant residues and green and animal manures provided a primary source of minerals for plant growth. In addition, beneficial effects on soil structure and water-holding capacity were attribute to the presence of organic matter. With the development of agricultural chemistry culminating in the work of Liebig in the nineteenth century, it was discovered that plants could make satisfactory growth in the absence of added organic matter if suitable kinds and amounts …


Exposure To Parathion Effect On General Population And Asthmatics, Robert S. Ganelin, Cipriano Cueto Jr., G. Allen Mail Jun 1964

Exposure To Parathion Effect On General Population And Asthmatics, Robert S. Ganelin, Cipriano Cueto Jr., G. Allen Mail

United States Food and Drug Administration: Publications

There has been much lay and medical concern regarding toxic effects of insecticides on the general population. In addition to direct toxic effects, it is suspected that insecticidal application has deleterious physical effects on persons with respiratory diseases. To evaluate some of these problems, the authors have attempted to quantitate actual absorption, symptoms, and laboratory evidence of intoxication in persons with varying degrees of exposure to parathion. By means of controlled observations, the respiratory effect of application of this compound on persons with bronchial asthma was also measured. The results suggest that the effect of this chemical on the general …

Studies On The Helminth Fauna Of Alaska. Xl. Strigea Gruis Sp. N., A Trematode Parasite Of Grus Canadensis (L.), Georges Dubois, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Strigea gruis sp. n. (Trematoda: Strigeata, Strigeidae) is described from the sandhill crane Grus c. canadensis (L.). Only one other species of Strigea (S. neotidis Bisseru, 1956) is known from birds of the order Gruiformes; it is distinguished from S. gruis by several characteristics including its slender form, campanulate anterior segment, size of pharynx and of eggs, position of ovary, and position and size of testes. S. gruis differs from two other species having a relatively large pharynx, S. sphaerula (Rudolphi, 1803) and S. intermedia Szidat, 1932, both parasites of corvids, in the form of the anterior segment and …


Isolation And Preliminary Characterization Of Bacteriophage Φμ-4, Fred Shafia, T.L. Thompson May 1964

Isolation And Preliminary Characterization Of Bacteriophage Φμ-4, Fred Shafia, T.L. Thompson

Papers in Microbiology

Isolation and preliminary characterization of bacteriophage Φμ-4. J. Bacteriol. 87:999-1002. 1964.-Bacteriophage Φμ-4 was isolated from lysogenic Bacillus stearothermophilus NU strain 4, and was propagated in strain 10 of the same species. The phage was extremely host-specific. One of the 23 strains of thermophiles screened for susceptibility supported phage replication. Plaque-forming efficiency of Φμ-4 depended on the agar medium employed and the temperature of incubation. Generally, media which resulted in restricted growth of the host cells on agar plates were most satisfactory for plaque formation. A latent period of 35 min was terminated in cell lysis and release of about 175 …


Arctic Health Research Center, U.S. Public Health Service, Robert L. Rausch May 1964

Arctic Health Research Center, U.S. Public Health Service, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A program of research in Alaska was initiated by the United States Public Health Service in 1948, with the establishment of a field station in temporary facilities located at Anchorage. This station, officially designated the Arctic Health Research Center in May 1950, was founded largely as the result of surveys of health conditions in Alaska conducted during 1946 and 1947 by two committees representing the American Medical Association. The reports of these committees led Congress to pass a special appropriation bill to support the investigation of health problems in Alaska.

Six research sections were set up within the first year. …


Culture And O-Hydroxycinnamic Acid Content Of Excised Melilotus Roots, Larry G. Williams, Francis A. Haskins, Herman J. Gorz May 1964

Culture And O-Hydroxycinnamic Acid Content Of Excised Melilotus Roots, Larry G. Williams, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Excised roots of biennial sweetclover were successfully cultured through repeated transfers on a modified White's medium solidified with agar. Roots also grew well in shaker-agitated liquid cultures over the pH range 4.5 to 7.0. Exposure of the cultures to bright illumination resulted in submaximal growth. No net synthesis of o-hydroxycinnamic acid was observed in the cultured roots.

Rabbit Control, Warren V. Johnson Mar 1964

Rabbit Control, Warren V. Johnson

Vertebrate Pest Conference Proceedings: 2nd (1964)

Common California rabbits comprise two major genera. One, the genus Sylvilagus, or true rabbit, is represented by the cottontail and brush rabbits. The second of the two major genera is the genus Lepus, or hares. These are erroneously called the jack rabbits and snow shoe rabbits. The common jack rabbit, Lepus californicus, is the most familiar one throughout California and portions of some of the other western states. Because of their size and abundance, they are by far the most destructive - so emphasis will be placed on this species throughout the balance of this report. The diet of the …


Animal Control In New Zealand, Walter E. Howard Mar 1964

Animal Control In New Zealand, Walter E. Howard

Vertebrate Pest Conference Proceedings: 2nd (1964)

New Zealand has a multiplicity of challenging animal-control problems, and all of them concern animals which man has intentionally introduced either for sport, food or fur. Since the beginning of European settlement in the 19th Century, approximately 53 species of mammals and 125 species of birds have been deliberately or accidentally introduced into New Zealand, and 34 birds and 31 mammals have become established (Wodzicki, 1950). The principal reasons the exotic big game animals (Riney, 1955), fur bearers and feral domestic livestock have been so destructive to certain habitats in New Zealand are because 1) some of the soils are …


Starlings In The Pacific Northwest, H. Nelson Elliott Mar 1964

Starlings In The Pacific Northwest, H. Nelson Elliott

Vertebrate Pest Conference Proceedings: 2nd (1964)

As is the case in many sections of the country today, starlings are causing increasing concern in the Pacific Northwest. When these birds were first recognized in Washington, Oregon and Idaho in the early 1940's only small numbers were seen, usually with blackbirds. During the 50's, however, the number of wintering starlings increased from a few birds, to thousands, with estimated flocks of 25,000 to 50,000 in western Oregon and along the Snake River Valley in Idaho and eastern Oregon. During the past five years winter resident populations in these areas have been estimated by the 100,000's, with some observers …


The Role Of Industry In Developing New Materials For Vertebrate Pest Control, G. Hermann, W. M. Zeck Mar 1964

The Role Of Industry In Developing New Materials For Vertebrate Pest Control, G. Hermann, W. M. Zeck

Vertebrate Pest Conference Proceedings: 2nd (1964)

In the first paper presented to you today by Dr. Spencer, an expert in the Animal Biology field and an official authority at the same time, you heard about the requirements imposed on a chemical in order to pass the different official hurdles before it ever will be accepted as a proven tool in wildlife management. Many characteristics have to be known and highly sophisticated tests have to be run. In many instances the governmental agency maintains its own screening, testing or analytical programs according to standard procedures. It would be impossible, however, for economic and time reasons to work …


Occurrence Of O-Hydroxycinnamic Acid In Species Of Melilotus And Trigonella, Herman J. Gorz, Francis A. Haskins Mar 1964

Occurrence Of O-Hydroxycinnamic Acid In Species Of Melilotus And Trigonella, Herman J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Leaf samples from available species of Melitotus and the closely related genus, Trigonella, were assayed for free as well as glucosidically bound cis- and trans-o-hydroxycinnamic acids. A qualitative evaluation of β-glucosidase activity also was made. In none of the species were appreciable quantities of the free acids detected. Of the 19 species of Melilotus sampled, 14 contained high levels of the o-hydroxycinnamic acid glucosides, one (M. infesta) was intermediate, and four were essentially free of these glucosides. The intermediate level in M. infesta is unlike that in any other species of Melilotus, …


The American Eagles And Their Economic Status, E. R. Kalmbach, Ralph H. Imler, Lee W. Arnold Jan 1964

The American Eagles And Their Economic Status, E. R. Kalmbach, Ralph H. Imler, Lee W. Arnold

United States Fish and Wildlife Service: Publications

For centuries eagles have captured the fancy of man the world over. Because of its extensive range in the northern hemisphere, the golden eagle is the most widely known of this group of birds. Its use in falconry was the sport of kings. The frequency of its appearance in royal coats of arms indicated its importance. It is the national emblem of Germany and Mexico.

In North America the bald eagle as well as the golden eagle represents this group of powerful birds of prey. The bald eagle is strictly an American species, and the founders of the United States …

The Reapportionment Cases: A Conservative Defense Of Individual Rights, Wallace M. Rudolph Jan 1964

The Reapportionment Cases: A Conservative Defense Of Individual Rights, Wallace M. Rudolph

Nebraska Law Review

The latest pronouncement of the Supreme Court in the reapportionment cases will be greeted by legal and political commentators as an example of a further usurpation of states rights by the Supreme Court. It will be shown, however, that (1) the decision was required by the equal protection clause, (2) the decision was foreordained by use of the equal protection clause, (3) the Court was not imposing its own views of political theory when it upheld the civil liberties of individuals and limited the power of political majorities, and (4) the decision will not destroy initiative or local individuality but …

Effect Of Amino Acid Supplementation Of Rations Containing Meat And Bone Scraps On Rate Of Gain, Feed Conversion And Digestibility Of Certain Ration Components For Growing-Finishing Swine, W. G. Luce, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Previous work at this station (Peo and Hudman, 1962) has shown that meat and bone scraps, when fed at levels from 5 to 10% of the total ration, significantly depress rate of gain of growing-finishing swine. Similar results have been reported by Bloss et al. (1953), Terrill et al. (1954), Meade and Teter (1957), and Becker and Jensen (1961).


Hyperparasitism, Michael G. Boosalis Jan 1964

Hyperparasitism, Michael G. Boosalis

Department of Plant Pathology: Faculty Publications

Much of the research on hyperparasitism has been of a descriptive nature, based primarily on studies with dual cultures in synthetic media. The main contributions from these investigations concern the host range of the parasite, the mode of penetration and infection, and the morphological changes of the host and the parasite resulting from parasitism.

More recent studies on hyperparasitism emphasize the effect of environmental factors, especially nutrition, on the susceptibility of the host. Research on the physiology of hyperparasitism has been limited. Nevertheless, this important aspect of the problem should continue to receive increased attention as hyperparasitism is extremely amenable …


Influence Of Surface Active Agents On Some Lactic Streptococci, R. B. Maxcy Jan 1964

Influence Of Surface Active Agents On Some Lactic Streptococci, R. B. Maxcy

Department of Food Science and Technology: Faculty Publications

Fatty acids and other surface active agents were used to clarify the relationship of surface activity to the inhibition of lactic streptococci. There was complete inhibition of lactic streptococci in media where surface activity exceeded a critical level. The effectiveness of inhibition by fatty acids, nonionic surface active agents, anionic surface active agents, decyl alcohol, growth medium, and temperature variation was directly related to the surface activity. The surface active agents created an unfavorable environment at most concentrations, rather than acting as a specific inhibitory substance to which the organisms were capable of adapting and thereafter resuming normal growth. The …

Economics Of Change In Market Structure, Conduct, And Performance The Baking Industry 1947-1958, Richard G. Walsh, Bert M. Evans

University Studies (University of Nebraska) (1888–1984)

Baking is one of the largest industries in the United States. Its sales, which exceed $4 billion annually, rank it third among the food processing industries, and thirteenth among all manufacturing industries. Bakery products account for nearly $1 out of every $10 spent by American consumers for food. Almost half of the domestic consumption of wheat flour is in the form of bread, rolls, cake, pie, doughnuts, sweet goods, and other perishable bakery products. While this study encompasses the perishable bakery products industry as defined by the U.S. Census Bureau, it focuses primarily on wholesale markets for white bread.
