Paleokarst And Associated Mineralization At The Linwood Mine, Scott County Iowa, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Operations at the Linwood Mine in Scott County, Iowa, have exposed, on two working levels, extensive pre-Pennsylvanian paleokarst and associated sediment fillings and mineralization in Middle Devonian limestones. Cavities in Davenport-Spring Grove host rocks range up to 270 meters in length and are virtually all filled with fluviatile sediment. Cavities in Cedar Rapids host rocks, on average, are smaller and some are unfilled. Limestone dissolution was controlled by high-angle fractures with a wide variety of orientations and by bedding plane and stylolitic partings. Dissolutional features on both levels of the mine provide evidence for phreatic and vadose processes. Most of …

Perceived Risks Of Emfs And Landowner Compensation, Linda J. Orel

RISK: Health, Safety & Environment (1990-2002)

Although public concerns about EMFs may eventually prove groundless, they can nevertheless depress the market value of residential property near powerlines. Ms. Orel argues that the scientific truth, as courts increasingly recognize, should play no role in determining whether or how much landowners should recover.

Getting Through The Door: Threshold Procedural Considerations In Right-To-Die Litigation, Sharon F. Dipaolo

RISK: Health, Safety & Environment (1990-2002)

Ms. DiPaolo explains how judges may use mootness, ripeness and standing to avoid getting involved in right-to-die cases. She argues that this may interfere with private decision making and be counterproductive.

Survey Of Hematozoa And Intestinal Helminths Infecting Green-Winged Teal In Guthrie County, Iowa, Rick Klann, Bryan Hellyer

Journal of the Iowa Academy of Science: JIAS

Five helminths and one sporozoan were recovered from 21 hunter-killed green-winged teal collected from Lakin Slough in Guthrie County, Iowa during October and November of 1991. The sporozoan, Leucocytozoon simondi, was identified in blood smears from all 21 teal. The helminths recovered from the alimentary tract included three trematodes, Cotylurus flabelliformis, Echinostoma trivolvis and Zygocotyle lunata; a hymenolepid tapeworm; and one acanthocephalan, Corynosoma constrictum. The ecological factors associated with infection by these parasites are discussed.

Inheritance And Number Of Genes Affecting Quantitative Traits Within F2 Maize Populations, D. H. Schmidt, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Populations derived from crosses of elite genotypes are commonly used in plant breeding programs. Knowledge of the genetic variation among individuals and their progenies within F2 populations is essential for effective selection of important traits. The genetic variation and number of effective factors affecting the expression of quantitative traits within 30 F2 maize (Zea mays L.) populations were determined by different methods suggested for study of F2 populations. Estimates of heritability and number of effective factors varied among F2 populations for each trait, primarily because of the differences in trait expression between parents of crosses and the environmental effects upon …

Annual Report Of The Iowa Academy Of Science, 1994-95, Paul E. Rider

Journal of the Iowa Academy of Science: JIAS

Since 1976, annual reports have served as a continuing record of the activities of the Iowa Academy of Science and an archive for its history. These augment the 100 year IAS history written in the centennial year of 1975.

This report covers the period from July 1, 1994 to June 30, 1995. It is based on the official records of the Academy (committee reports, Board minutes, correspondence) as well as the recollections, impressions and thoughts of the author.

Hydrogeology Of The Devonian-Silurian Carbonate Aquifer, Northern Cedar Rapids, Iowa, Keith E. Schilling

Journal of the Iowa Academy of Science: JIAS

The hydrogeology of the Devonian-Silurian carbonate aquifer was investigated at a hazardous waste site in northern Cedar Rapids, Iowa. Data collected at the project site included bedrock cores, specific capacity measurements in discrete packer intervals and monitoring wells, hydraulic-head measurements and groundwater samples collected from select Devonian and Silurian wells.

Cavity Protection Techniques For Red-Cockaded Woodpeckers, Warren G. Montague

Journal of the Arkansas Academy of Science

Population growth of red-cockaded woodpeckers (Picoides borealis) is often limited by the availability of suitable cavities. Structural damage to natural and artificial cavities intended for use by P. borealis is common. Roost and nest cavities of P. borealis often become occupied by other cavity-dependent species. Techniques for preventing damage to artificial cavities and for deterring southern flying squirrel (Glaucomys volans) use of otherwise serviceable cavities are described. Such cavity protection techniques may be necessary to prevent extirpation of small, isolated populations of P. borealis.

5'-Nucleotidase And Thrombin-Like Activities Of Selected Crotalid Venoms, Ali M.S. Shams, Dewey H. Sifford, Bob D. Johnson

Journal of the Arkansas Academy of Science

Thrombin-like activities were not observed inCrotalus basiliscus, C. molossus and C. scutulatus scutulatus crude venoms. 5'-Nucleotidase specific activities of 0.863, 0.273 and 5.520 units/mg of crude venom protein were observed inC. basiliscus, C. molossus and C. s. scutulatus venoms, respectively. Concanavalin ASepharose 4 B (Con A)affinitychromatography yielded two fractions from each of the crude venoms. Ineach instance, both fractions exhibited 5'-nucleotidase activities and the Con A-binding proteins had higher activities than the Con A-nonbinding proteins. 5'-Nucleotidase activities inthe DEAESephadex A-50 chromatographic fractions were localized in the first elution fraction and the last fraction(s) to elute. EDTAhad no effect on the …
