Archaeology: Puzzle Of The Past: An Exhibit Design, Kristine Eyheralde

Presidential Scholars Theses (1990 – 2006)

Archaeology: Puzzle of the Past is a design for a museum exhibit to better explain archaeology to the public. Its purpose is to change the audience's perspective from one of object orientation to visualization of archaeology as a process. The exhibit utilizes a chronological and concrete approach to move the visitors through the major steps in the archaeological process -- including survey, excavation, labwork, and interpretation -- as they occur within the parameters of a fictitious archaeological site. In addition, interactive exercises are designed to be included within each area to reinforce the message.

Theoretical Concepts Of Evil In Counseling, James Kimsey

Graduate Research Papers

Evil can harm an individual in many ways, including psychologically, and, therefore, may be a factor that needs to be addressed in counseling. Many human conditions or problems could be seen as either evil or caused by evil. This is important to children and to people who work for them. This paper is an investigation regarding the origins of evil. Three theoretical approaches based in psychology will be reviewed: Freudian, Behavioral, and Third Force. Implications for school counselors will be briefly treated.

Social Interaction In The College Union Environment: An Examination Of The Physical Setting, Richard David Fekel

Graduate Research Papers

The purpose of this paper is to better understand the effect of the college union physical environment upon informal social interaction. The application of such knowledge may enable college union practitioners to design college union physical settings that enhance, rather than impede, student-faculty and peer informal interaction. This paper briefly presents pertinent research concerning the outcomes associated with student-faculty and peer interaction. Relevant person-environment interaction and physical-environmental models are examined. The social relationship between architecture and human interaction behavior is addressed, as well as the consequential affect of interior seating and furniture arrangements on informal interaction. The ambient environment which …

Selective Recovery Of Β-Galactosidase With Charged Fusion Tails Using Ion-Exchange Membranes, Erika A. Thiem, Meng H. Heng

Journal of the Iowa Academy of Science: JIAS

We explored the feasibility of attaching charged tails to a target protein, in this case β-galactosidase, for selective recovery. In this process, an ion-exchange membrane was used for selective binding and release of β-galactosidase with the attached purification fusions. Strength of binding and purity of eluate increased with increasing tail length. In addition, activity yield was improved with the implementation of an intermediate partial elution recycle procedure.

Effects Of Competition And Predation On Prothonotary Warblers And House Wrens Nesting In Eastern Iowa, Timothy Brush

Journal of the Iowa Academy of Science: JIAS

In a fragmented midwestern floodplain forest, a small Prothonotary Warbler (Protonotaria citrea) population experienced high competition with House Wrens (Troglodytes aedon) and mammalian nest predation in 1988-89. Despite the provision of 3 types of nest boxes and higher water levels, Prothonotary Warblers did not nest successfully and decreased in the fragmented forest in 1990-91. House Wrens used >90% of the nest boxes in both years. Wren territories doubled within the nestbox area, while remaining constant on an unmanipulated area. In contrast, a larger warbler population had high nesting success during 1990-91 in a relatively unfragmented, wetter forest tract. Such forests, …

Use Of Ion Exchange Membranes For Selective Recovery Of Aspergillus Awamori Glucoamylase And Phage T4 Lysozyme, Deborah K. Stafslein, Jeff M. Hunter, Craig E. Forney

Journal of the Iowa Academy of Science: JIAS

Our research examined whether enhanced separation and purification of mutant enzymes could be obtained on ion-exchange membranes. Solutions of three mutants of Aspergillus awamori glucoamylase were passed through an anionic exchange membrane, as well as one mutant of T4 lysozyme through a cationic exchange membrane. The mutant enzymes were modified by adding "charged fusions'', polypeptides of either aspartic acid residues to increase the overall negative charge of the enzyme or arginine residues to increase the overall positive charge. The effect of the mutations on the purification of glucoamylase from a "modified" fermentation broth were examined at two different elution pHs, …

Age And Developmental History Of Iowa Fens, C. A. Thompson, E. A. Bettis Iii

Journal of the Iowa Academy of Science: JIAS

Iowa fens are small, mineorotrophic peatlands maintained by shallow groundwater. Eighteen fen sites located across northern Iowa were mapped and radiocarbon dated to assess the timing of initial peat accumulation. The radiocarbon ages span the Holocene, ranging from 1,240 to 10,900 B.P.; however most fens postdate 5,000 yr B.P. The dominance of late-Holocene ages suggests that Holocene climatic change may have strongly influenced the record of peat accumulation. During the mid-Holocene Iowa was warmer and drier than at present, and peat was degraded or accumulated slowly in fens. The range of ages also implies that the commencement and subsequent rate …

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.

Removal Of Magnetic Impurities From Strontium Copper Oxychloride, Colleen B. Eads, Carol J. Kosmicke, Lance L. Miller

Journal of the Iowa Academy of Science: JIAS

Analyses of a copper-deficient series of Strontium Copper Oxychloride polycrystalline samples are reported. Magnetic susceptibility, X-ray powder diffraction, and differential thermal analyses show a small Curie-type magnetic signal correlates with =0.6% (excess) copper ions in the nominally stoichiometric material. The analyses also imply that the extra magnetic signal is from an impurity phase, possibly related to Strontium Copper Oxide. The concentration of the impurity phase can be controlled by varying the copper stoichiometry.

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 …

Parallel Algorithms For Solving Partial Differential Equations, Stacy Pschenica

Journal of the Iowa Academy of Science: JIAS

This paper describes the use of a parallel computer system in applying a finite difference method to solve various types of partial differential equations. A sequential implementation of this method was made parallel by essentially spatially decomposing the problem domain into pieces that could be separately analyzed and assigning each piece to a processor in a large, multi-processor system. Although this approach is attractive in theory, it suffers in practice because of inter-processor interactions. Thus, particular emphasis was placed on developing efficient methods for the sharing of information among the processors.

Initially, a simple two-dimensional board game, life, was implemented …

Analysis Of An Iowa Aridity Index In Relationship To Climate And Crop Yield, Soumare Harouna, R. E. Carlson

Journal of the Iowa Academy of Science: JIAS

An aridity index and its components, temperature and precipitation, for the period from 1900 through April 1993 were defined and characterized. This index describes the anomalous behavior of both temperature and precipitation over time. Our intent was to examine climate variability in Iowa. Moving mean and standard deviations over various lengths of time were calculated from three time series. We found that these indices fluctuate considerably from year to year and from month to month. The lowest aridity index values occurred in the recent summer of 1992, and the highest occurred during the very drought-prone 1930s. The 12-month moving mean …

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) …
