Relation Between S2 And Later Generation Testcrosses Of Two Corn Populations, S. M. Lile, A. R. Hallauer Jan 1994

Relation Between S2 And Later Generation Testcrosses Of Two Corn Populations, S. M. Lile, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Determination of the relative combining abilities of corn (Zea mays L.) inbred lines is an important feature of applied corn breeding programs. Combining ability is measured by the relative performance of a line in testcrosses to one or more testers. Inbred lines from BS13(S2)Cl and BSCB1(R)C7 corn populations were evaluated at the S2 and later generations of inbreeding. Intense selection was practiced among and within lines during inbreeding to develop the S5-equivalent and S8 generation lines. The objective of this study was to determine if the combining ability of lines in early generations (S2) …

Nuclear Waste Into Glass: Viscosities Of Molten Analogs Of Radioactive Waste Disposal Media, Betty Pang, Kenneth E. Windom Jan 1994

Nuclear Waste Into Glass: Viscosities Of Molten Analogs Of Radioactive Waste Disposal Media, Betty Pang, Kenneth E. Windom

Journal of the Iowa Academy of Science: JIAS

Disposal of high-level radioactive wastes involves vitrification of a mixture of waste products and borosilicate glass frit. Monitoring the composition of the mixture is critical to the control of the vitrification process, bur is difficult because of the high levels or radioactive components in the mixture. Synthetic non-radioactive analogs of the products from nuclear reprocessing have been prepared and their viscosities measured over a wide range of temperature appropriate to those of the vitrification process. Preliminary results indicate that viscosity is a linear function of composition, under isothermal conditions, for a limited compositional range that encompasses the proportions of waste …

Water Quality Monitoring (1988 To 1991) At The Iowa Academy Of Science's Parish Farm, Grundy County, Iowa, Brenda K. Nations, George R. Hallberg Jan 1994

Water Quality Monitoring (1988 To 1991) At The Iowa Academy Of Science's Parish Farm, Grundy County, Iowa, Brenda K. Nations, George R. Hallberg

Journal of the Iowa Academy of Science: JIAS

In May 1988 sampling was initiated to evaluate water quality in relation to management practices at Parish Farm, which is owned by Iowa Academy of Science. Initial results showed tile-line effluent to have high concentrations of nitrate-nitrogen (N03-N). Twelve monitoring wells were installed over a one year period to analyze shallow groundwater at the farm. The wells, tile lines, and surface water were sampled monthly, through October, 1991, and the water analyzed for N03-N and some pesticides. N03-N concentrations varied, related to landuse and management of adjacent areas. Greater N03-N concentrations were …

Nomenclatural Changes For Some Diatoms Found In Iowa, David B. Czarnecki Jan 1994

Nomenclatural Changes For Some Diatoms Found In Iowa, David B. Czarnecki

Journal of the Iowa Academy of Science: JIAS

Nomenclatural revisions for four diatom taxa found in Iowa, two of which are presently maintained in the Loras College Freshwater Diatom Culture Collection (FDCC), are necessary because of systematic interpretations of the Division Bacillariophyta. Achnanthidium hauckianum (Grun.) Czarnecki comb. nov. was originally assigned to the genus Achnanthes Bory. Three taxa were previously assigned to the morphologically diverse genus Navicula Bory. These are Cavinula weinzierlii (Schimanski) Czarnecki comb. nov., Craticula cuspidata var. major [(Meist.) Czarnecki comb. nov. and] Craticula halophila var. subcapitata (0str.) Czarnecki comb. nov.

Classification System For The Natural Vegetation Of Arkansas, Thomas L. Foti, Martin Blaney, Xiaojun Li, Kimberly G. Smith Jan 1994

Classification System For The Natural Vegetation Of Arkansas, Thomas L. Foti, Martin Blaney, Xiaojun Li, Kimberly G. Smith

Journal of the Arkansas Academy of Science

We present a hierarchical classification system for existing natural vegetation of Arkansas based on the United Nations Educational, Scientific and Cultural Organization (UNESCO) system. It incorporates aspects of systems in use by the Nature Conservancy, Arkansas Natural Heritage Commission, Arkansas Game and Fish Commission, Society of American Foresters, and United States Forest Service, as well as data on potential vegetation from maps by E.E. Dale and A.W. Kuchler. A total of 18 physiognomic cover types are recognized for natural terrestrial cover, 6 for palustrine cover, and 4 each for lacustrine cover and riverine cover. Over 200 community types are recognized, …

Sanitation And Parasitism At Harpers Ferry, West Virginia, Karl J. Reinhard Jan 1994

Sanitation And Parasitism At Harpers Ferry, West Virginia, Karl J. Reinhard

Karl Reinhard Publications

One focus of historical archaeology at Harpers Ferry National Historical Park, West Virginia, is tracing the development of sanitation at the town through the 1800s and 1900s. Historical documentation indicates that there was a degree of resistance to the modernization of village sanitation. This study attempts to verify this resistance through examination of privy soils for parasites indicative of fecalborne disease, specifically the helminth species Ascaris lumbricoides and Trichuris trichiura. The presence of these parasites in the early 1900s would indicate that fecal-borne disease due to poor sanitation continued to be an aspect of town life. The analysis revealed the …

Otitis Media, Mastoiditis, And Infracranial Lesions In Two Plains Indian Children, Robert W. Mann, Douglas W. Owsley, Karl J. Reinhard Jan 1994

Otitis Media, Mastoiditis, And Infracranial Lesions In Two Plains Indian Children, Robert W. Mann, Douglas W. Owsley, Karl J. Reinhard

Karl Reinhard Publications

One disease condition that is common to nearly all children is otitis media, also known as middle ear disease. Although most people speak of it as a middle ear "infection," other causes such as neoplasm (tumor) can result in manifestations and symptoms mimicking an infectious process. This paper presents findings related to osseous lesions in two Indian children, approximately three to five years of age, who died with otitis media and infracranial lesions. Through macroscopic and radiographic analysis, it is possible to show that one child probably suffered from tuberculosis and the other from histiocytosis X. From an epidemiological and …

Trade, Contact, And Female Health In Northeast Nebraska, Karl Reinhard, Larry Tieszen, Karin L. Sandness, Lynae M. Beiningen, Elizabeth Miller, A. Mohammad Ghazi, Christiana E. Miewald, Sandra V. Barnum Jan 1994

Trade, Contact, And Female Health In Northeast Nebraska, Karl Reinhard, Larry Tieszen, Karin L. Sandness, Lynae M. Beiningen, Elizabeth Miller, A. Mohammad Ghazi, Christiana E. Miewald, Sandra V. Barnum

Karl Reinhard Publications

Most scholars are understandably preoccupied with the impact of Europeans on native peoples who were passive, unwilling, or resistant participants in that contact. We present in this chapter a different case. The Missouri River tribes, including the Omaha and Ponca, willingly engaged in relations with Euramericans, especially in the fur trade that dominated interaction in this region. The time frame for this study is 1780- 1820, a period when interaction between individual traders and Native Americans was replaced by the dominance of the American Fur Company in organized exploitation of the Missouri River lands and peoples. This involvement later contributed …

Public Attitudes Toward Animal Research: Some International Comparisons, Ralph Pifer, Kinya Shimizu, Linda Pifer Jan 1994

Public Attitudes Toward Animal Research: Some International Comparisons, Ralph Pifer, Kinya Shimizu, Linda Pifer

Attitudes Toward Animal Research Collection

A comparative analysis was made of the public's attitudes toward the use of animals in scientific research in 15 different nations. The intensity of opposition to animal research was found to vary from relatively low levels in Japan and the United States to much higher levels in France, Belgium, and Great Britain. More women than men were opposed to animal research in all 15 nations. Scientific knowledge, or the lack of knowledge, was not found to have a consistent relationship with attitudes toward animal research. Concern about the environment was found to be related to opposition to animal research in …
