Exchangeable Potassium And Clay Minerals In Selected Iowa Soil Profiles, J. J. Hanway, R. L. Handy, A. D. Scott

Proceedings of the Iowa Academy of Science

Exchangeable K values and X-ray diffraction patterns were obtained for soil samples from several modal profiles of nine different soil series in Iowa. Exchangeable K in "moist" subsoils was consistently low and almost always lower than in the "moist" surface soil. Drying increased exchangeable K in all the soils, but the increase due to drying varied between soil series and with depth in the profile of each series. Reversion of exchangeable K to a non-exchangeable form on rewetting the oven-dry samples generally increased with depth in the profile but the exchangeable K never decreased to the original "moist" level. X-ray …

Estimate Of Slope Classes By Counties In Iowa, R. W. Arnold, L. E. Tyler, F. F. Riecken

Proceedings of the Iowa Academy of Science

The proportion of land in given slope classes has been estimated for Iowa counties from a randomly selected sample. The sample, approximately 2 percent of the land area of the state, consists of about 4,500 individual tracts, each about 160 acres in size. A detailed soil map was made of each tract, using a 4-inch-to-the-mile aerial photograph as a base map, thus providing the basic information for a physical land-condition inventory. The data from the soil maps were projected to give estimates of physical land conditions by counties and for the state as a whole. On a state basis, nearly …

Characteristics Of The Floyd And Some Related Soils In Floyd And Bremer Counties, Iowa, J. A. Phillips, F. F. Riecken

Proceedings of the Iowa Academy of Science

This study deals with imperfectly and poorly drained soils generally considered to have developed under prairie from a parent material consisting of a sandy-silt mantle overlying Iowan glacial loam till. Three Floyd profiles, two profiles of the proposed Tripoli series (Floyd, poorly drained variant), and one Clyde profile were studied in the field and in the laboratory. Results indicate that the Tripoli soils should be separated from the Floyd and mapped as a separate series. The present concepts of the Floyd series as a minimal Brunizem and the Tripoli as a minimal Wiesenboden are substantiated by field studies and laboratory …

The Impact Of Usage Studies Upon Recent Grammar Texts, Donald Keith Chiquet

Dissertations and Theses @ UNI

The purpose of this study is to show to what degree writers of grammar texts have been influenced by the controversy over usage as a criterion of grammatical acceptability. More specifically, the problem is to show the degree of agreement between textbook writers and liberal grammarians. This information will be used to determine the degree to which textbooks are liberal or traditional. If the texts are liberal, it may be considered that the impact of liberal grammarians upon textbook writers has been great. If these grammar texts are not liberal, or if they are no more liberal than they were …

The Development Of Ear Prirnordia Of Zea In Relation To Position On The Plant, John E. Sass

Proceedings of the Iowa Academy of Science

The development of auxiliary buds of a yellow dent maize hybrid was studied. Seven buds at acropetally successive nodes survived at least to 68 days after planting and became pistillate inflorescences, potential ears. Meiosis occurred in the basal ovaries of the upper two ears after 68 days, when the styles were 2 mm. long, and complete embryo sacs were present by 71 days. The two upper ears attained approximately the same morphological and cytological stage between 68 and 71 days. The top bud invariably became the harvestable ear. The failure of complete development of the second ear is not ascribed …

Presidential Address - The Academy Of The State And The State Of The Academy, William C. Oelke

Proceedings of the Iowa Academy of Science

Our experimentation with the arrangement of the Academy program this year, largely due to the insight and initiative of Dr. Don Lewis of the State University of Iowa, and ably forwarded by Dr. Sherwood Tuttle and others from our host institution, seems to have been most successful if one can judge from the results so far. This rearrangement of the program, placing the address of the president in juxtaposition with the business meeting, allows and indeed makes advisable a change in its character.

Distribution Of Manganese In A Bio-Topo Sequence Of Southeastern Iowa Soils, E. C. A. Runge, L. De Leon

Proceedings of the Iowa Academy of Science

Manganese extractable by sodium hydrosulfite was determined for 9 soil profiles of a bio-topo (vegetation and drainage) sequence in southeastern Iowa. The distribution of manganese in the soils studied is influenced by vegetation, drainage, and pH. Under prairie vegetation the manganese is evenly distributed with depth in the well-drained soil, but with increasing wetness of the soil profile, manganese is apparently lost from the A1 horizon and accumulates in the lower part of the B horizon. Manganese accumulates in the A₁ and A₂ horizons of the well-drained soils developed under forest vegetation, but in profiles of increasing wetness …

Notes On Hibernating Bats In Dubuque County Caves, Ted J. Muir, Emmett Polder

Proceedings of the Iowa Academy of Science

In the fall and winter of 1958 and 1959 four species of bats, Myotis lucifugus, Myotis sodalis, Eptesicus fuscus, and Pipistrellus subftavus, were found in five Dubuque County caves. M. sodalis was a new species record for Iowa. Migration of bats into the caves began when the minimum temperature dropped to 24° F. The greatest increase in cave population occurred when the daytime high temperature was below freezing and nighttime lows ranged from 13° F. to 1° F. Midwinter copulation of E. fuscus was observed, and drinking of condensed water on cave ceilings by M. lucifugus was noted. No intercave …

Some Blood Parasites From Birds In Central Iowa, John N. Farmer

Proceedings of the Iowa Academy of Science

During 1957, 1958, and 1959, blood smears from 568 birds were examined. Ninety-nine (17.25%) of these birds were found to harbor haemosporidian parasites. Four species of birds harbored Plasmodium, four species were infected with Leucocytozoon, and five species with Haemoproteus. Trypanosomes and microfilariae were observed in two species.

Cottontails With "Horns", Arnold O. Haugen

Proceedings of the Iowa Academy of Science

Published information on papillomas, commonly called horns, on cottontails (Sylvilagus floridanus) in Iowa dates back to 1907. Specimens of horned rabbits are on record from Woodbury, Pottawattamie, Cherokee, Franklin, and Boone counties. Those from the last two counties were necropsied at Iowa State University in 1958 and 1959-60, respectively. Information from conservation officers and biologists shows sight records for a number of years past for at least 16 additional counties. The malady seems to be limited almost entirely to the western half of the state.

A Biometric Technique For Reaction Tissue Research, Graeme P. Berlyn

Proceedings of the Iowa Academy of Science

Images of sections of tissue taken from the upper side of leaning stems of Populus deltoides were projected on a paper grid system. Specimens were oriented so that the cambium and the last three annual increments were included in cross section. Counts of stimulated and non-stimulated cells in randomly selected grids were recorded. This procedure provides a means of subjecting the incidence of tension wood and other cytohistological phenomena to statistical analysis.

A Preliminary Survey Of Some Midwestern Plants For Substances Inhibiting Human Plasma Cholinesterase In Vitro, Wallace H. Orgell, Kunda A. Vaidya, Eugene W. Hamilton

Proceedings of the Iowa Academy of Science

Substances which inhibit the action of human plasma cholinesterase in vitro have been found in aqueous extracts of various members of the plant family Solanaceae. A preliminary survey of some weedy and cultivated midwestern representatives of this family revealed eleven active species in six genera: Datura, Lycopersicon, Nicotiana, Petunia, Physalis, and Solanum. A member each of the genera Capsicum and Lycium were inactive. Inhibitory substances were not found in thirty-one species representing nineteen plant families other than Solanaceae.

Effect Of Seed Size And Hulls Upon X-Ray Sensitivity Of Oat Seeds, C. L. Gonzalez, K. J. Frey

Proceedings of the Iowa Academy of Science

Apparently the hull covering on oat seeds afforded some protection to the seed from X-rays, although the degree of protection varied among varieties. At X-ray dosages of 30,000r to 40,000r the large seeds were damaged more than the small ones when measured by germination percentage or reduction in seedling vigor. The damage from X-rays was not completely related to the germ sizes of the 2 seed classes.

Profile Characteristics Of Some Forest-Formed Soils Derived From Iowan Till, J. M. Soileau, F. F. Riecken

Proceedings of the Iowa Academy of Science

Three profiles were collected in Bremer and Floyd counties to represent the proposed Coggon series; detailed field and laboratory studies were conducted on these profiles. The Coggon soils have developed under forest vegetation from a "two-story" parent material consisting of a silty mantle-pebble band-glacial till sequence. Being formed from Iowan-age glacial till, the Coggon profiles exhibit an amount of development that is low compared to other Gray-Brown Podzolic soils of Iowa. Coarser parent material might possibly explain why Coggon is less developed than the Weller soils, which are formed from presumably younger, loessial parent material. On the other hand, the …

A Study Of The Effects Of The 1958 Junior High School Seminar In Science And Mathematics, Iowa State Teachers College, Upon The Pupils’ Attitudes Toward And Interest In Science And Mathematics, William Richards Babcock

Dissertations and Theses @ UNI

The current emphasis which the "atomic age" has placed upon the education of "gifted" or "talented" pupils in science and mathematics has provided educators with an opportunity to devise and implement new and unique programs in the elementary and secondary schools. Educators have utilized two approaches in meeting the challenge--acceleration and enrichment. Many secondary schools in all parts of the United States are offering pupils opportunity to take more advanced course work than the traditional curriculum had allowed. College courses, as well as high school subjects, are being offered at the high school level both during the regular academic year …

Dissertations and Theses @ UNI

The purpose of this study has been to examine the various problems attendant to the production of operettas, with recommended procedures for solutions to these problems, and with particular attention to those problems inherent in the smaller secondary schools. An attempt has been made to operate on the most practical level with theoretical explanations being confined to the minimum.

A Proposed Handbook For Iowa Coordinators Of Distributive Education, Orville Lee Allen

Dissertations and Theses @ UNI

Distributive education is a nation-wide training program designed to prepare workers for more effective distribution of goods and services through programs of instruction at both the adult and secondary levels.1 Reimbursable distributive education was initiated in Iowa in 1937. In 1958 Iowa had twenty-four high school cooperative part-time programs and ten adult programs in operation.

Empathic Ability Compared As To Environmental Setting And Concept Of Measurement, Alice Jane Anderson

Dissertations and Theses @ UNI

Since the turn of the century there has been a growing controversy as to the definition and significance of the term "empathy" in the separate fields of esthetics and psychology. People concerned with both areas use a similar basic definition - the ability to "feel into" an object or another person. It is in the attainment of this ability and the ways in which we can use it that the definitions vary. In the esthetic sense, empathy is thought of as a process of identification and projection. A person watching a play, for instance, projects himself into the actions and …
