Experimental Program With The Iowa State University Undergraduate 1.5 Mev Cyclotron, Ronnie R. Burns

Proceedings of the Iowa Academy of Science

The Iowa State University 1.5 Mev undergraduate cyclotron experimental program is divided between cyclotron technology and nuclear physics experiments. Accelerator technology work has been done in the determination of the shape of the resonance curve as a function of the magnetic field strength and radius, the determination of magnetic tune-down as a function of radius, and the measurement of the vertical excursions of the beam. Nuclear physics experiments have been performed with the light elements.

Air Ion Densities In A Smoke-Filled Room, Philip J. Lorenz

Proceedings of the Iowa Academy of Science

This study was concerned with the differentiation and measurement of small, intermediate, and large ion densities in a sealed room. It was found that the background density of large negative ions exceeded that of any other class. Under conditions of tobacco smoke pollution, large ions of both positive and negative charge were the major components of the air ion population. This was accompanied by a persistent attrition of high mobility ions both during and after smoking.

Fungus Flora Of Panicum Virgatum L., J. A. Helin

Proceedings of the Iowa Academy of Science

The pathogenic fungi collected on Panicum virgatum in Iowa included Elsinoe sp., Phyllachora graminis, Colletotrichum graminicola, Selenophoma donacis, Puccinia panici, Tilletia maclagani, and Uromyces graminicola. Those which were saprophytic or of doubtful pathogenicity included Ophiobolus herpotrichus, Leptosphaeria microscopica, Mycosphaerella recutita, Phaeoseptoria elymi, and Phaeoseptoria festucae. Reported for the first time on Panicum virgatum are Elsinoe sp., Ophiobolus herpotrichus, Leptosphaeria microscopica, Mycosphaerella recutita, Phaeoseptoria elymi, and P. festucae. This is the initial report of Colletotrichum graminicola and Selenophoma donacis in Iowa on this host.

The Isolation Of Fusarium Moniliforme Sheld. From Corn Kernels, Richard W. Ikenberry

Proceedings of the Iowa Academy of Science

Kernels representing six inbred corn lines were soaked in sterile distilled water for 24 and 48 hours, with and without aeration during soaking. When the kernels were plated on a nutritive medium following such treatments, frequency of appearance of Fusarium moniliforme on kernels was directly associated with longer periods of soaking, and with continuous aeration provided during soaking. Such variations in recovery of the organisms from the kernel, depending on isolation procedure used, strongly emphasize the fact that failure to isolate a fungus from host tissue does not necessarily mean the fungus is absent.

Isolation Of Pyrenochaeta Terrestris From Onion Roots, Robert P. Borgman, J. C. Horton

Proceedings of the Iowa Academy of Science

A comparison was made of various techniques for isolating Pyrenochaeta terrestris (Hansen) Gorenz et al. from growing onion roots. Water agar was as suitable as potato dextrose agar (0.5% dextrose) and is recommended to avoid contamination. Texas L 303, Iowa Yellow Globe 51, and Trapp's Downing Yellow Globe used as trap crops were equally efficient. Maximum infection of the early planting occurred earlier than a later planting.

Extent And Distribution Of Soils In Depressional Areas In The Clarion-Nicollet-Webster Soil Association In Lowa, D. F. Slusher, R. W. Arnold, R. Protz

Proceedings of the Iowa Academy of Science

The extent and distribution of soils that occur in depressional areas in the Clarion-Nicollet-Webster soil association have been estimated for Iowa counties from a randomly selected sample. The sample consisted of detailed soil maps of approximately 1000 quarter-section (each about 160 acres), or about 2 percent of the total land area. The data from the soil maps of the samples were projected to give estimates of soil conditions by counties and for the area as a whole. The acreage of depressional soils is estimated to be 4.8 percent of the total soil association area with significant variation between counties. The …

The Iowa State University 1.5 Mev Undergraduate Cyclotron, Daniel J. Mcguire

Proceedings of the Iowa Academy of Science

This paper presents a general description of a small cyclotron built and used by undergraduates of the Iowa State University Physics Department. This machine was the first operating small cyclotron capable of useful nuclear reactions to be built by an undergraduate group. Specifications of the machine are given. The paper also includes a short review of cyclotron action and a description of some of the auxiliary equipment used in the ISU cyclotron laboratory.

Relationship Between The California Bearing Ratio And The Unconfined Compressive Strength Of Sand-Cement Mixtures, C. A. O'Flaherty, H. T. David, D. T. Davidson

Proceedings of the Iowa Academy of Science

This investigation showed that a true functional relationship, valid over a wide range of experimental conditions, does not exist between the results obtained by two methods of evaluating the strength of a cement-treated sandy soil. These two methods are the California Bearing Ratio test and the unconfined compressive strength test. However the equation, log CBR = 1.115 + 0.660 log UCS, can be used as a working relationship between the two tests under varying experimental conditions. It was concluded that a true functional relationship likely does exist for a given experimental condition, i.e., where only one experimental condition varied at …

A Survey Of Articles Pertaining To Education Appearing In Selected Non-Professional Magazines During The Five-Year Period 1953-1957, Gerald Eugene Dockum

Dissertations and Theses @ UNI

There are very few people who are not earnestly interested in education, especially if they have children of their own enrolled in school. Nearly all of these people realize that the school is one of the most important agencies which exert an influence upon their children and which should provide them with the tools to develop for themselves a future of the type parents normally desire for their children. This, plus the fact that education is publicly-supported, makes a vast majority of the people of our country vitally interested in our system of public education.

Problems In The Use Of Plant Growth Chambers, J. C. Horton, D. C. Foley

Proceedings of the Iowa Academy of Science

Plant growth chambers cannot duplicate all of the intricacies of continually changing environments, but properly designed chambers can produce daily and hourly changes in light and temperature with reasonable precision. Gradient, the most objectionable type of temperature variation, can be minimized by increasing air circulation and removing lamp heat as quickly as possible. Bulb age and temperature influence light intensity.

Fusarium Blight Of Soybeans, John Dunleavy

Proceedings of the Iowa Academy of Science

Fusarium orthoceras produced necrosis of succulent root tissues of soybean seedlings and infected tips of lateral roots of older plants. Pods and seeds were most susceptible to fungus penetration after maturity. High relative humidity was necessary for infection of seeds. Maximum stand reduction and yield loss under field conditions were obtained when seeds were sown in Fusarium-contaminated soil before rains. In a greenhouse the disease was most destructive when plants were grown in soil at 100-percent water-holding capacity at 21° C. The disease was less damaging to plants grown in soil at the same moisture level at 27°. Seedlings grown …

Seed Weight As A Measure Of Response Of Oats To Crown Rust Infection, M. D. Simons, J. A. Browning

Proceedings of the Iowa Academy of Science

Average seed weight, as determined by samples consisting of 100 seeds, was significantly correlated with yield and bushel weight in fungicide and varietal response trials. In one fungicide trial seed weight was a more sensitive measure of rust control than yield or bushel weight. In varietal trials seed weight response to the crown rust fungus of oats grown in hill plots was significantly correlated with yield response in 32-square-foot plots.

Testing Oats In The Field With Specific Races Of Crown Rust, M. D. Simons

Proceedings of the Iowa Academy of Science

Different methods of testing were compared under field conditions. Inoculation procedures in which rust spores were applied directly to the plants were generally not as satisfactory as procedures in which highly susceptible rust-spreader plants were inoculated heavily early in the season. Certain strains of oats were shown to be resistant to two of the races of crown rust used and susceptible to the third. Other strains were resistant to all three races.

White And Black Crappies In Clear Lake, Summer, 1960, Richard A. Neal

Proceedings of the Iowa Academy of Science

Studies of white crappie, Pomoxis annularis, and black crappie, Pomoxis nigromaculatus, showed a shift in the population in Clear Lake during the past 10 years from a dominance of black to white crappies. A decrease in the rate of growth of black crappies was shown for this period although the rate of growth of white crappies has remained constant. The food habits of white and black crappies were very similar. The three most important food items were Cladocera, fish, and insect larvae, in that order. Young-of-the-year samples indicated that the trend toward white crappies was continuing. Turbidity was suggested as …

Wood Duck Roosting Flights At Paint Creek, Lowa, Dale Hein

Proceedings of the Iowa Academy of Science

Wood duck roosting flights were studied at a marsh near the mouth of Paint Creek, Allamakee County, Iowa, during late summer and fall of 1959 and 1960. Evening roosting flight counts were superior to morning counts for estimating roosting populations. Changes in times of flights and illumination associated with flights were noted as the season advanced. The roosting population built up to a pre-migration peak in mid-September. Counts fluctuated erratically after migration started about October 1, and the roost was abandoned in early November. Data collected at Paint Creek Roost were typical in general of those collected at the other …

Conserving Iowa's Prehistoric Heritage, Marshall Mckusick

Proceedings of the Iowa Academy of Science

A hundred years of farming and relic hunting has destroyed much of Iowa's archeological resources. An active program of research is currently underway at the State University of Iowa in order to preserve these prehistoric remains before they are entirely lost. It will require a strenuous effort to salvage enough information to piece together the ten thousand years of Iowa's past. Current research emphasis is upon publishing reports and organizing the results of previous work throughout the state. After this phase of the program is completed a series of excavations will be made in different parts of the state to …

Problems Of Paleontological Preservation In Iowa, W. D. Frankforter

Proceedings of the Iowa Academy of Science

A brief review of vertebrate paleontological work in Iowa reveals an early utilization of fossils in Pleistocene studies followed by a lapse in collecting and research until revived during the past decade. Legal measures enacted to protect paleontological materials have, in the opinion of many paleontologists, resulted in numerous federal and state regulations which are unrealistic and a hindrance to scientific endeavor. Efforts to modify or remove federal rules and regulations governing fossils are discussed. Legal restrictions do not constitute the primary problems of paleontological conservation in many states, including Iowa. Instead, the problems are those of (1) public education …

Guides For The Elementary Teacher In The Playing Of Selected Simple Rhythmic, Melodic And Harmonic Instruments, Lorraine Salome Augustyn

Dissertations and Theses @ UNI

"There are no first, second, third fourth, fifth or sixth graders in the elementary schools of Appleton, Wisconsin. Children are ungraded. They are neither promoted nor failed. They do not receive report cards. Under Appleton's Continuous Progress Plan, youngsters move along as fast as their individual abilities can take them. Free from the artificial limits of grade requirements they push on beyond these arbitrary boundaries. In the process they meet the toughest competitive challenge in the world--the challenge to achieve their highest capacity.'

Thus, does Arthur Morse describe the educational philosophy of the Appleton Elementary Public Schools. This philosophy is …

Informational Materials In The Homes And Achievement In School Of Elementary Students At Iowa Falls, Iowa, Kenneth L. Christensen

Dissertations and Theses @ UNI

In this rapidly changing world children are engaged with problems of science, social studies, literature, and world events. Their interests have been widened by travel, radio, television, newspapers, and magazines. Their curiosities have been aroused by new experiences and they search for related facts. The textbook formerly occupied a central position in learning; but in the complex society of the present, neither a single textbook nor multiple texts are adequate to enable the school to fulfill its responsibility for the education of children. Not only does a modern educational program demand more informational materials than did the narrow "essentials" program …

Introits, Hymns, Anthems, And Responses For The Reorganized Church Of Jesus Christ Of Latter Day Saints, Donald L. Breshears

Dissertations and Theses @ UNI

The writer is a member of The Reorganized Church of Jesus Christ of Latter Day Saints. Since a knowledge of some of the history and beliefs of this denomination is essential for an understanding of the problem undertaken, it will be necessary to explain them to some extent. The Church of Jesus Christ of Latter Day Saints was founded on April 6,1830, by Joseph Smith on the premise that God, being unchangeable, can and does communicate His will to men on earth now, as in former days. Because of their peculiar social and religious philosophy and the need for self-protection …

The Bounty System In Iowa, David W. Waller, Paul L. Errington

Proceedings of the Iowa Academy of Science

A study of the history and functioning of the bounty system in Iowa demonstrates the legal weaknesses, costliness, and general ineffectiveness of this method of controlling undesired wildlife. The bounty laws have developed by trial and error. Early laws were simplified and primarily intended for the protection of livestock from the larger predators, notably wolves. After 1900, the program was expanded to include nuisance species and, more recently, in intended behalf of game protection. Bounty rates were changed many times in response to changes in attitudes toward troublesome wildlife and the cost of maintaining the program. Because of bounty frauds, …

Life History Of The Quillback And Highfin Carpsuckers In The Des Moines River, David Vanicek

Proceedings of the Iowa Academy of Science

An age and growth study was made of 705 quillback, Carpiodes cyprinus, and 399 highfin carpsuckers, C. velifer, taken from the Des Moines River, Boone County, Iowa, from June 1 to August 24, 1960. The length-weight relationship, body-scale relationship and coefficient of condition of these two species are very similar, but the quillback is a larger and faster growing fish. Difficulty was encountered in distinguishing young quillbacks and highfins from the young of the other two species of carpsuckers found in the river.
