Gross Structure Of The Cervical Region Of The Uterus Of White-Tailed Deer, John E. Morris

Proceedings of the Iowa Academy of Science

The uterine cervix of the white-tailed deer, Odocoileus virginianus, consists of the narrowed-down multiple-valved part between the vagina and the hollow thinner-walled uterus proper. The length of the cervix of a mature doe in December may vary from 40 mm to 84 mm. It is composed of four to six, but generally of five, heavily muscled valves with the openings through the valves alternating dorsally and ventrally. This arrangement of valves results in an undulating or twisted passageway through the cervix. Age and reproductive history influences variation in size. The inside surface of the cervix is covered with small longitudinal …

Age, Growth, Fecundity And Food Habits Of Fantail Darters In Boone County, Lowa, James R. Karr

Proceedings of the Iowa Academy of Science

Although 117 fantail darters (Etheostoma flabellare) were collected from Bluff Creek, Boone County, Iowa, during summer 1962 and winter 1962-63, only 1 was found in the Des Moines River. Slenderhead darters occupy the similar riffle areas in the river. Female fantail darters were 18.7, 34.8, and 42.4 mm at the first through the third annuli, respectively, and male darters were 18.5, 36.7, 59.0, and 62.0 mm at the first through the fourth annuli, respectively. No females were found that had formed a fourth annulus. Average coefficient of condition for 104 fantail darters was 1.749. Length-weight relationships for males and …

Morphometric Study Of Two Drainage Basins Near Iowa City, Iowa, Marcus E. Milling, Sherwood D. Tuttle

Proceedings of the Iowa Academy of Science

A morphometric study was made of the adjoining drainage basins of east-flowing Old Man Creek and Clear Creek in Johnson and Iowa counties, Iowa. In terms of the parameters measured, these basins are essentially similar. They agree with "laws" for drainage basins proposed by Horton and are therefore "normal" rather than "misfit". Part of the Clear Creek basin was invaded by Iowan ice and this probably accounts for some abnormal data. Distinct longitudinal asymmetry and obviously steeper south valley walls are probably best explained by the differences in loess thickness on valley sides.

Clay Mineralogy Of A Gumbotil, Wilbourne A. Kelley Iii, Clara Ho

Proceedings of the Iowa Academy of Science

Investigation of the clay minerals in a gumbotil associated with the Mahaska soil series in Keokuk County, Iowa, indicates that the principal clay mineral is a dioctahedral calcium montmorillonite. Other clay minerals present in this gumbotil are kaolinite and mica, although they are in much smaller percentages. The investigation also pointed out difficulties involved in analyzing this type of soil by standard X-ray procedures and the complications introduced in the analysis of soil samples with high iron content utilizing standard accepted diffraction techniques.

Three Color Photometry Of The Total Eclipse Of The Moon, December 29, 1963, John R. Zink, Satoshi Matsushima

Proceedings of the Iowa Academy of Science

A three-color photometry of the eclipsed moon was carried out with a 12-inch reflector during the total eclipse on December 30. 1963. In order to examine the intensity and color distribution of refracted light in the umbral region, the observation was centered at Mare Crisium during the course of the eclipse. The decrease in brightness was found to be about 16 magnitudes for each of the three colors, and no significant reddening effect was observed during the totality. The magnitude differences between different colors appear to be nearly the same on the uneclipsed and the totally eclipsed moon.

An Inexpensive 8000 Gauss Laboratory Electromagnet, Richard D. Adams, Gerald Pfeiffer

Adaptation As Related To The Introversion-Extroversion Dimension, Earl D. Scott, David Wilkinson

Proceedings of the Iowa Academy of Science

Thirteen young adult men were given a test for introversion-extroversion. They were then tested to determine the number of presentations of a noxious stimulus which was required for adaption to the stimulus to take place, as measured by the galvanic skin response. It was found that extroverts adapted with significantly fewer stimulus presentations than did introverts. The results were related to Eysenck's theory concerning the introversion-extroversion dimension and conditionability.

An Ecological Analysis Of Silver Lake Fen I. The Aquatic Metazoan Fauna, Lawrence Eickstaedt

Proceedings of the Iowa Academy of Science

The aquatic metazoan fauna and physicochemical features of the Silver Lake Fen, Dickinson County, Iowa, were investigated. The pools displayed high values of alkalinity, calcium and total hardness, sulfate and dissolved solids; neutral to alkaline conditions; and extreme diurnal variability in dissolved gasses, pH and temperature. Fifty metazoan species have been collected from this unique and rigorous habitat, with nine species being most abundant and widespread. Possible causal factors dealing with population dispersion are discussed.

Summer Emigrations Of The Frog Rana Pipiens In Northwestern Iowa, Richard V. Bovbjerg, Ann M. Bovbjerg

Proceedings of the Iowa Academy of Science

During the summers of 1961, 1962, and 1963, mass emigrations of Rana pipiens pipiens Schreber occurred at the end of the first week in July. The intensity of the movement varied in the three years. Environmental causes for this movement were considered; temperature changes, precipitation or crowding do not seem to be operating. Samples of the tadpole populations were examined and the metamorphic changes prior to emigration are rapid and regular. With final metamorphosis into juvenile frogs, the emigration suddenly begins. It appears to be triggered by internal events related to maturation.

Ecological Observations On Iowa Shore Flies (Diptera, Ephydridae), D. L. Deonier

Gizzard Lesions Associated With Haemoproteus Sacharovi Infections Of Pigeons, John N. Farmer

Proceedings of the Iowa Academy of Science

Becker et al. (1956) described abnormally enlarged spleens and granular gizzards observed in several killed pigeons. Blood films made from these particular birds were diagnosed as positive for Haemoproteus sacharovi. Since mourning doves represent a host for this parasite, four infected doves were killed and selected tissues sectioned and examined in an attempt to locate sites of exoerythrocytic schizogony. None were observed although the spleens of these birds were markedly swollen and colored a mottled purplish-black. Concerning pigeons, however, granular gizzards were observed in each of eight H. sacharovi infected pigeons killed. Examination of sections of infected gizzard revealed areas …

Upper Devonian And Lower Mississippian Conodont Faunas, North-Central Iowa, Wayne I. Anderson

Proceedings of the Iowa Academy of Science

Conodonts are rare in the Shell Rock Formation, but they support the previous assignment of this formation to the lower part of the Upper Devonian. Conodont species diagnostic of the Lower Palmatolepis gigas Zone (Upper Devonian, toIγ) occur in the upper part of the Juniper Hill and in the lower Cerro Gordo members of the Lime Creek Formation. The ranges of conodont species occurring in the Sheffield Formation are indicative of zones toI^δ -tollα. The conodont faunas from the Aplington Formation is meager but may indicate zone toIV or toV. Conodonts from …

Characteristics Of Instrumentation Personnel In The Aerospace Manufacturing Industry Of The New York Metropolitan Area, Kennith Glenn Gordon

Dissertations and Theses @ UNI

As the aerospace manufacturing industry of the New York Metropolitan Area becomes more deeply involved in industrial, scientific, and military activities, it seems reasonable to expect a corresponding growth in the knowledge and understanding of that industry by the engineering and education professions alike . The engineering profession would require an accurate description of the technical character, while the education profession would be concerned with developing a better understanding of the educational ramifications of this new industry. A study of the entire industry would have required the use of resources beyond the power of the writer. However, it was decided …

A Study Of Adult Typewriting In The Public Schools Of Iowa, Fall 1963, John W. Banks

Dissertations and Theses @ UNI

Typewriting has been one of the most popular adult courses for many years. There are reasons for this. These reasons have been variously assumed, but very little study or investigation has been made to discover the reasons for interest in adult typewriting or to determine the status and nature of the adult typewriting programs.

A Study Of Selected Employers’ Opinions Regarding The Terminal Education Programs Of Secondary Schools In Davenport, Iowa, Gerald Dwight Clemmensen

Dissertations and Theses @ UNI

One of the failings of American education today is its inability to meet the needs of the average student in high school. Because of this failing, many young people, mostly boys, will drop out of high school sometime between beginning the tenth grade and finishing the twelfth grade. Because American education does not meet the needs of the average student, many youths, job hunting immediately following graduation from high school, will face a more difficult time in locating some type of employment than their elders did during the early 1930's.

Thou Shalt Keep Christmas: An Operetta For Upper Elementary Grades Or Junior High School Performance, Marion Gertrude Arends

Dissertations and Theses @ UNI

Numerous operettas with Christmas themes, some sacred, some secular, some employing familiar carols, and some entirely original in both text and lyrics have been written for the elementary grades and junior high. There are many pageants depicting Christmas customs and using carols from many countries of the world. However, an investigation of available material has not revealed an operetta based strictly on carols and customs of just one country. The carols and customs of Old England three and four centuries ago are particularly interesting because of the fact that our founding fathers came from the shores of that country, and …

Differences In Class Rank Between Boys And Girls In Graduating Classes Of Iowa Public Secondary Schools, Dave John Cook

Dissertations and Theses @ UNI

For many years, educators have noted that girls seem to attain higher class rank than boys while attending secondary schools. It appears that this idea has been accepted a priori and that little research effort has been put forth to determine the magnitude of the differences which exist. It is a matter of conjecture at the present time as to how great the differences must be before they will be considered to be serious problems.

It was the purpose of this study (1) to determine whether significant differences existed between the class standing of boys and the class standing of …

A Study Of The Public Relations Program Of The Valley Park School, Cedar Falls, Iowa, Puran L. Rajpal

Dissertations and Theses @ UNI

Public relations is a relatively new field in educational administration and it has possibilities for further study that have scarcely been explored. "It is new in the sense that the importance of this field was not formally recognized until a few years ago when provisions were made for it in the management of educational institutions. In recent years educational leaders have been increasingly aware of the importance of effective school public relationships. James L. Hymes, Jr., said, "Home-school relations is a new field. Very little research and experimentation are available as direct guides.”

It was the purpose of this study …

Educators are always alert and watchful for new and better instruments of measurement to be used in serving the student in gaining new insights into his concept of self. Of all the areas of individual differences which lend themselves to testing there is none in greater need of development than that of personality assessment. Any new test, any new approach to this assessment, is worthy of careful research and analysis. While studying at the State College of Iowa, the writer was introduced to the Beck Word-Color Association Test. In the analysis of two gifted boys in Cedar Falls, Iowa, it …

Three Hypotheses Concerning Art Nouveau, Ralph H. Gaede

Dissertations and Theses @ UNI

A style of art, known to us today as Art Nouveau, developed throughout the countries of western Europe during the 1890's. As a style, Art Nouveau had its effect in varying degrees upon most of the art forms: architecture, the applied arts and decorative design, painting, sculpture, illustration, bookbinding, printmaking, ceramics, jewelry-making, and other minor art forms. Then, after encompassing this wide variety of creative activity, the forms of Art Nouveau faded and died out just prior to the First World War (1910-1915).
