Molecular Differentiation Of Alfalfa Weevil Strains (Coleoptera: Curculionidae), S. J. Erney, K. P. Pruess, S. D. Danielson, T. O. Powers

Department of Entomology: Faculty Publications

Mitochondrial DNA was amplified and sequenced from eastern, western, and Egyptian strains of alfalfa weevil, Hypera postica (Gyllenhal). Eastern and Egyptian weevils differed at only 2 nucleotide sites in 1,031 base pairs sequenced; western weevils differed by 5% sequence divergence. Three restriction sites were identified which separated eastern and western haplotypes. No intrastrain polymorphism was detected in 150 weevils from Nebraska. Collections from Lincoln in eastern Nebraska and Scottsbluff in western Nebraska were fixed for the eastern and western haplotypes, respectively. Eastern and western haplotypes were found together in the same fields in a broad overlap region in central Nebraska.

Strategy Use In Process Writing: A Survey Of Esl Students' Strategy Use In L1 Writing And In L2 Writing, Mei-Ya Jung

All Graduate Theses, Dissertations, and Other Capstone Projects

Nowadays, an increasing number of students from different countries study in the United States. These English-as-a-second-language (ESL) students have to use English as a necessary tool to make instruction comprehensible and to express their own meaning in the academic context. Of the four language skills (listening, speaking, reading, and writing), writing is generally recognized as most difficult to acquire. This paper examines the question whether students' first language (L1) writing skills may be available for them to use in the process of second language (L2) writing.

Determination Of Toxicity And Bioactivity Of Four Organic Insecticides Recommended For Control Of Pests In Vegetable Crops, Hugo Humberto Rodriguez Salvatierra

Theses and Dissertations

This work was done to determine the toxicity and bioactivity of four organic insecticides and ultimately find answers about their toxic potential. Thus, farmers will be able to take the necessary precautions when using them. This investigation was performed in the Laboratory of Biology of the Eastern University Center (Chiquimula) at the University of San Carlos, Guatemala. In order to determine the acute toxicity and bioactivity of the organic insecticides ANONAZO, BOX, AJORIN, and NARCISO, five doses were used in albino mice and three concentrations in nauplii of brine shrimp (Artemia salina). The finney basic program was used for calculating …

American Widowers With School-Age Children : An Exploratory Study Of Role Change And Role Conflict, Douglas Edward O'Neill

Electronic Theses and Dissertations

This study assessed the effects that the death of a wife has on the roles of the widower when he becomes a single parent with school-age children. The literature review guided the study towards the areas of the family, roles of husband and wife, crises in families, specific crises which men become a single parent and men as single parents. An interactionist perspective was used with Znanieckis' Social Role theory to gain insight on the widowers processing of roles and social position. An exploratory survey of a sample population (N=46) of widowers with school-age children was used to gather data …

The Vital Element, Jennifer Mcnab

Graduate Research Papers

Integrating technology into curriculum requires educators to have a working knowledge of using technology in the educational setting. However, technology integration is often an oversight in staff development. Educators are more likely to use technology to their full potential if a support system is in place and proper training of how to use technology in their classroom is available.

The purpose of this study was to investigate how educators use computers to enhance the learning experience for students. Educators from around the United States answered the request for sharing motivational ideas for incorporating computers into the classroom. These innovative activities …

Leaf Gas Exchange And Growth Of Flood-Tolerant And Flood-Sensitive Tree Species Under Low Soil Redox Conditions, S. R. Pezeshki, J. H. Pardue, R. D. Delaune

Faculty Publications

Seedlings of Taxodium distichum L., Quercus lyrata Walt. and Q. falcata var. pagodaefolia Ell. were grown for 22 days in a rhizotron system providing two soil redox potential regimes, +170 mV (low Eh) and +560 mV (high Eh). Leaf chlorophyll concentration and gas exchange, root alcohol dehydrogenase (ADH) activity, root and leaf ethylene production, and growth and biomass partitioning were measured. In response to the low Eh soil treatment, stomatal conductance was reduced in Q. falcata and Q. lyrata but not in T. distichum, whereas net photosynthesis was reduced significantly in all species; however, net photosynthesis in T. distichum began …

Modeling The Vertical Distribution Of Oyster Larvae In Response To Environmental Conditions, Margaret M. Dekshenieks, Eileen E. Hofmann, John M. Klinck, Eric N. Powell

CCPO Publications

A size-structured, time and vertically-dependent model was used to investigate the effects of water column structure on the distribution of larvae of the oyster Crassostrea virginica. Formulations used to model larval growth and behavior are based upon laboratory studies. Simulated vertical larval distributions obtained for conditions representative of a well-mixed, partially stratified and strongly stratified water column illustrate the effect that salinity and temperature gradients have on moderating larval swimming and hence on larvae vertical location. For well-mixed conditions, smaller larvae are dispersed throughout most of the water column. For strongly stratified conditions, the smaller-sized larvae cluster within the …

Automatic Correlation And Calibration Of Noisy Sensor Readings Using Elite Genetic Algorithms, R. R. Brooks, S. S. Iyengar, J. Chen

Faculty Publications

This paper explores an image processing application of optimization techniques which entails interpreting noisy sensor data. The application is a generalization of image correlation; we attempt to find the optimal gruence which matches two overlapping gray scale images corrupted with noise. Both tabu search and genetic algorithms are used to find the parameters which match the two images. A genetic algorithm approach using an elitist reproduction scheme is found to provide significantly superior results.

The Effects Of Glucose And Fatty Acids On Enhanced Biological Phosphorus Removal Using A Sequencing Batch Reactor, Tarek Zaki Khouri

Retrospective Theses and Dissertations

Two anaerobic/aerobic sequencing batch reactors (SBRs) were used to evaluate enhanced biological phosphorus removal (EBPR). The first SBR, designated the Glucose SBR, was run for a period of four months. It received a synthetic wastewater plus glucose as a supplemental carbon source. The second SBR, the Isovaleric SBR, was run for three months. During the first month, isovaleric acid was its supplemental carbon source while for the remaining time period, no supplemental carbon source was added to the feed. Steady-state data from the SBR receiving isovalerate yielded the highest phosphorus (P) removals observed during the study, with a mixed liquor …

The Relationship Of Ethnic Identity Development To Cognitive Development In Preschool Children, Teresa L. Henegar

Honors Capstones

Current research seeks to determine when children first become aware of salient ethnic differences. It has been therorized that children's ethnic identity development follows the same sequence as that of cognitive development. The focus of this thesis is on children's ethnic identity development and the relationship of ethnic identity development to cognitive development. This thesis is based on literature on Piaget's theory on children's cognitive development and recent research on ethnic and identity development. It is done in accord with the current study, "Cognitive Development and The Perception of Skin Color in Young Children," by Dr. Shi-Ruei Sherry Fang, Human …

Assessment Of Arsenate Resistance In Haloalkaliphilic Archaea, Taeko Matsushima

Honors Capstones

Haloalkaliphilic Archaea, Natronococcus occultus is one of a few organisms which survive in soda lakes. It grows optimally in 3.4 M NaCl and pH 9. It is suspected that this organism has resistances to heavy metals because its distant relative, haloneutrophilic Archaea, had shown resistance to several different heavy metals. Although no haloneutrophilic Archaea had shown resistance to arsenate, several eubacteria had been tested positive for arsenate resistance. Natronococcus occultus was tested for arsenate resistance, partially because arsenate stays in solution even in 3.4 M NaCl and at pH9. The uptake rates of phosphate and arsenate are compared to investigate …

What's Sex Got To Do With It? Challenges For Incorporating Sexuality Into Family Planning Programs, Kirsten Moore, Judith F. Helzner

Reproductive Health

In February 1996, IPPF/WHR and the Population Council’s Ebert Program on Critical Issues in Reproductive Health jointly hosted a meeting on the challenge of incorporating sexuality into family planning. This report was compiled after organizers concluded that the ideas and strategies presented during the meeting merited wider recognition and debate within the family planning field. The meeting examined five myths that have prevented family planning and reproductive health services from dealing directly with issues of sexuality and gender. The report draws principally on the discussions from the meeting as well as on the perspectives of the organizers. The authors hope …
