Book Review: Iowa's Minerals: Their Occurrence, Origins, Industries, And Lore, Raymond R. Anderson Jan 1999

Book Review: Iowa's Minerals: Their Occurrence, Origins, Industries, And Lore, Raymond R. Anderson

Journal of the Iowa Academy of Science: JIAS

Iowa's Minerals: Their Occurrence, Origins, Industries, and Lore. Paul Garvin. 1998. University of Iowa Press, Iowa City IA. vii + 260 pages. ISBN 0-87745-626-7 hdbd., ISBN 0-87745-627-5 (pbk.).

A mineral is defined as a "naturally occurring, chemically homogeneous crystalline solid." Every mineral has a composition, structure, and characteristics that make it uniquely different from every other mineral. In his new book, Paul Garvin, Professor of Geology at Cornell College in Mount Vernon, Iowa, presents a uniquely different discussion of Iowa's Minerals. While this book does contain the requisite discussions of mineral origins, chemistry, crystallography, and other descriptive information, Garvin enhances …


The Habitat And Distribution Of The Stinkpot, Sternotherus Odoratus, In Iowa, Kristi K. Sutton, James L. Christiansen Jan 1999

The Habitat And Distribution Of The Stinkpot, Sternotherus Odoratus, In Iowa, Kristi K. Sutton, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Twenty years of study have shown that the stinkpot, Sternotherus odoratus and the Illinois mud turtle (Kinosternon flavescens spooneri) occur in Iowa primarily in the Mississippi Alluvial Plain. Even though the turtles are found within a kilometer of each other, they are never sympatric. Illinois mud turtles are most often associated with ephemeral ponds and soils of nearly pure sand (Sparta sand and Chelsea loamy fine sand), whereas stinkpots inhabit permanent water, often fed by cold springs, and are limited to sandy, loamy soils (Aquolls and Perks sandy loam). Even though several new localities have been discovered for stinkpots, population …

Community Composition Of Dry Prairie In Iowa And Southeast Nebraska, Thomas R. Rosburg Jan 1999

Community Composition Of Dry Prairie In Iowa And Southeast Nebraska, Thomas R. Rosburg

Journal of the Iowa Academy of Science: JIAS

Results from quantitative research on the community composition of dry prairies across Iowa were consolidated from three different studies completed since 1983. Information is provided on the distribution and abundance of 204 dry prairie species. The most abundant species included little bluestem (Schizachyrium scoparium (Michx.) Nash), big bluestem (Andropogon gerardii Vitman), side-oats grama (Bouteloua curtipendula (Michx.) Torrey), prairie dropseed (Sporobolus heterolepis (Gray) Gray) and Kentucky bluegrass (Poa pratensis L.). Multivariate analyses were completed using two independent measures of species abundance-relative cover and community constancy. When relative cover was used to determine community composition, the abundance of graminoids (tallgrasses vs. mid-grasses) …

Maintaining Transitive Closure Of Graphs In Sql, Guozhu Dong, Leonid Libkin, Jianwen Su, Limsoon Wong Jan 1999

Maintaining Transitive Closure Of Graphs In Sql, Guozhu Dong, Leonid Libkin, Jianwen Su, Limsoon Wong

Kno.e.sis Publications

It is common knowledge that relational calculus and even SQL are not expressive enough to express recursive queries such as the transitive closure. In a real database system, one can overcome this problem by storing a graph together with its transitive closure and maintaining the latter whenever updates to the former occur. This leads to the concept of an incremental evaluation system, or IES.

Much is already known about the theory of IES but very little has been translated into practice. The purpose of this paper is to fill in this gap by providing a gentle introduction to and …

Osmia Spp. Reared In Artificial Nesting Sites In A Backyard Environment, R. L. Wilson, C. A. Abel, S. G. Mcclurg

Journal of the Iowa Academy of Science: JIAS

Controlled pollination in field cages is used at the United States Department of Agriculture - Agricultural Research Service North Central Regional Plane Introduction Station (NCRPIS) for seed increase of several plane species. Honey bees, Apis mellifera L., have been used almost exclusively for several years. Recently we began investigating other pollinating insects for controlled pollination. 0smia cornifrons (Radoszkowski), a solitary bee imported from Japan, has been an excellent early-season pollinator. We placed domiciles of these bees in backyards of the NCRPIS staff to aid us in providing adequate numbers of bees for use in field cages the following growing season. …

A Municipal Inventory And Evaluation Of Natural Areas: History And Methodology, William R. Norris, Donald R. Farrar Jan 1999

A Municipal Inventory And Evaluation Of Natural Areas: History And Methodology, William R. Norris, Donald R. Farrar

Journal of the Iowa Academy of Science: JIAS

An inventory of natural areas in the vicinity of Ames, Iowa was conducted (1990-1994) in response to conflicts arising when significant natural areas were encountered on lands approved for development by the City of Ames (Iowa) Planning Office. Methods for objective evaluation of woodland and prairie quality were developed for use during the inventory. The woodland method is based on four components: I) Diversity of expected species, H) Structure of canopy and understory layers, III) Fidelity of species to the habitat and IV) absence of Introduced Species. Rules are explicitly stated for the scoring of each component for both the …


Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck Jan 1999

Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck

Journal of the Arkansas Academy of Science

Peck and Heidt (1985) proposed a linear model that demonstrated that for gray fox (Urocyon cinereoargenteus) in Arkansas; total fur harvests from 1966-1982 were highly correlated with mean pelt values. Single variable models using linear regression analysis of current season pelt values (CSPV) and previous season pelt values (PSPV) were designed to predict total fur harvests. These models demonstrated high correlations (r =0.93 and 0.89, respectively). In the past 15 years, markets for fur have undergone many perturbations within Arkansas and overseas resulting in great changes in mean pelt prices. In an attempt to evaluate the continued performance of the …


Effects Of Varied Intensity Resistance Training In Combination With Extra Mass-Bearing Exercise On Bone Adaptations In Ovariectomized And Sham Operated Sprague Dawley Rats, Donna Quimby, Kathy Hall Jan 1999

Effects Of Varied Intensity Resistance Training In Combination With Extra Mass-Bearing Exercise On Bone Adaptations In Ovariectomized And Sham Operated Sprague Dawley Rats, Donna Quimby, Kathy Hall

Journal of the Arkansas Academy of Science

This experiment was designed to study the effects of intensity of exercise on bone adaptations in ovariectomized and sham operated 12 week old rats. Eighty Sprague Dawley rats were divided by mass into two equal groups (mean = 197 g). One group was ovariectomized (OVX); the other sham (S) operated. Each surgery group was then subdivided by mass into four exercise intensity groups. The exercise intensity groups were created by loading additional mass (percent of animals body mass, 0%, 3%, 6% and 9%) on each animal in combination with treadmill running (10 m/min.; 30 min./day; 4 days/wk.; for 7 weeks). …

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard Jan 1999

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Few studies of monogamous canids have addressed regurgitation in the context of extended parental care and alloparental care within family groups. We studied food transfer by regurgitation in a pack of wolves on Ellesmere Island, North West Territories, Canada, during 6 summers from 1988 through 1996. All adult wolves, including yearlings and a post-reproductive female, regurgitated food. Although individuals regurgitated up to five times per bout, the overall ratio of regurgitations per bout was 1.5. Pups were more likely to receive regurgitations (81%) than the breeding female (14%) or auxiliaries (6%). The breeding male regurgitated mostly to the breeding female …

Infoharness: Managing Distributed, Heterogeneous Information, Kshitij Shah, Amit P. Sheth

Kno.e.sis Publications

Today, important information is scattered in so many places, formats, and media, that getting the right information at the right time and place is an extremely difficult task. Developing a single software product, for example, includes the creation of documents ranging from the requirements specification and project schedules to marketing presentations, multimedia tutorials, and more. Each document may be created by a different person using a different tool, and each may be stored in a different place. InfoHarness is an information integration system, platform, and tool set that addresses these problems, managing huge amounts of heterogeneous information in a distributed …

Potential Associations Among Genetic Markers In The Serotonergic System And The Antisocial Alcoholism Subtype, E. M. Hill, S. F. Stoltenberg, M. Burmeister, M. Closser, R. A. Zucker Jan 1999

Potential Associations Among Genetic Markers In The Serotonergic System And The Antisocial Alcoholism Subtype, E. M. Hill, S. F. Stoltenberg, M. Burmeister, M. Closser, R. A. Zucker

Department of Psychology: Faculty Publications

Alcoholism is transmitted in families. The complexity and heterogeneity of this disorder has made it difficult to identify specific genetic correlates. One design with the potential to do so is the family-based association study, in which the frequencies of genetic polymorphisms are compared between affected and nonaffected members. Reduced central serotonin neurotransmission is associated with features of an antisocial subtype of alcoholism, although a primary deficit has not been traced to a particular component. Genetic markers related to the serotonergic system have been identified, located, and cloned. If associations can be discovered, the development process for pharmacotherapy could be facilitated. …

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck Jan 1999

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck

All Master's Theses

Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …

Attitudes To Biotechnology And Genetically Modified Food : A Review, Juliana Rose Cannon Jan 1999

Attitudes To Biotechnology And Genetically Modified Food : A Review, Juliana Rose Cannon

Theses : Honours

Debate surrounds the introduction of new biotechnological applications such as genetically modified food (GMF). With this in mind a critical review of the debate, it's emerging themes, and approaches to measurement was undertaken. The intention of this review was to argue that while existing empirical measures have advanced our understanding of attitudes to GMF, they are limited both conceptually and methodologically. Overall, the validity and reliability of research support was compromised. Conceptually, attitudes to GMF were composed of a number of potential dimensions that have yet to be measured. Adherence to sound scale construction techniques may facilitate more reliable and …

Nutritional And Health Behavior Of The Indigenous Pregnant Women In The Community Of Tunshi-San Nicolas, Chimborazo Province, Sandra Ordonez Gavilanez

Theses and Dissertations

The nutritional food situation in our country is alarming, by what has been classified as a major public health problem, their principle manifestation is the protein malnutrition- energy, with a high prevalence in urban zones- marginal and rural population. It is considered that the main causes that originate on one hand are still deteriorating at a level of income in the popular sectors with the consequent impossibility of access to basic services such as housing, education, stable jobs, health services (drinking water, sewage, etc.) appropriate food regimes, greatly affecting those vulnerable groups such as children and women in fertile years. …


General Diagnosis And Services Developed In The Corral De Piedra Village, San Juan Ermita, Chiquimula, Servin Ardany Flores Galdámez Jan 1999

General Diagnosis And Services Developed In The Corral De Piedra Village, San Juan Ermita, Chiquimula, Servin Ardany Flores Galdámez

Theses and Dissertations

The Corral de Piedra community is located in Chiquimula, Guatemala. The main agricultural activities are corn and bean production, small-scale gardens, and small animal production, such as poultry and pigs. The crop areas are predominantly located on lands with slopes between 12 and 55%, presenting low fertility conditions and poor moisture retention capabilities. In addition, local crop varieties have low productivity potentials and the winter season is characterized by poorly distributed and erratic periods of rain. The Benson Institute introduced a technology transfer model to increase and diversify agricultural production, while preserving current natural resources. An integral part of this …


Alpha Status, Dominance, And Division Of Labor In Wolf Packs, L. David Mech Jan 1999

Alpha Status, Dominance, And Division Of Labor In Wolf Packs, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The prevailing view of a wolf (Canis lupus) pack is that of a group of individuals ever vying for dominance but held in check by the “alpha” pair, the alpha male and alpha female. Most research on the social dynamics of wolf packs, however, has been conducted on non-natural assortments of captive wolves. Here I describe the wolf-pack social order as it occurs in nature, discuss the alpha concept and social dominance and submission, and present data on the precise relationships among members in free-living packs, based on a literature review and 13 summers of observations of wolves …
