Work In Progress: The Wsu Model For Engineering Mathematics Education, Nathan W. Klingbeil, Richard Mercer, Kuldip S. Rattan, Michael L. Raymer, David B. Reynolds

Kno.e.sis Publications

This paper summarizes progress to date on the WSU model for engineering mathematics education, an NSF funded curriculum reform initiative at Wright State University. The WSU model seeks to increase student retention, motivation and success in engineering through application-driven, just-in-time engineering math instruction. The WSU approach involves the development of a novel freshman-level engineering mathematics course EGR 101, as well as a large-scale restructuring of the engineering curriculum. By removing traditional math prerequisites and moving core engineering courses earlier in the program, the WSU model shifts the traditional emphasis on math prerequisite requirements to an emphasis on engineering motivation for …

Plant Organellar Protein Targeting: A Traffic Plan Still Under Construction, Sally Ann Mackenzie

Center for Plant Science Innovation: Faculty Publications

It has long been understood that specific features of a protein and its corresponding import apparatus dictate the behavior of mitochondrial proteins in their intracellular targeting behavior. In plants, the process by which proteins are directed to organelles has been influenced uniquely by the introduction to the cell of plastids. Parallel functions carried out within the mitochondrion and plastid permit the sharing of proteins and emergence of mechanisms to facilitate dual-targeting of the nuclear-encoded products to both compartments. These include transcriptional and translational variations, relaxation of translation initiation controls and conditional cellular influences. Details of the dual targeting system are …

Evolution Of Sexual Dimorphism And Male Dimorphism In The Expression Of Beetle Horns: Phylogenetic Evidence For Modularity, Evolutionary Lability, And Constraint, Douglas J. Emlen, John Hunt, Leigh W. Simmons

Biological Sciences Faculty Publications

Beetle horns are enlarged outgrowths of the head or thorax that are used as weapons in contests over access to mates. Horn development is typically confined to males (sexual dimorphism) and often only to the largest males (male dimorphism). Both types of dimorphism result from endocrine threshold mechanisms that coordinate cell proliferation near the end of the larval period. Here, we map the presence/absence of each type of dimorphism onto a recent phylogeny for the genus Onthophagits (Coleoptera: Scarabaeidae) to explore how horn development has changed over time. Our results provide empirical support for several recent predictions regarding the evolutionary …

Parc Mutations In Fluoroquinolone-Resistant Borrelia Burgdorfeti, Kendal M. Galbraith, Amanda C. Ng, Betsy J. Eggers, Craig R. Kuchel, Christian H. Eggers, D. Scott Samuels

Biological Sciences Faculty Publications

We have isolated in vitro fluoroquinolone-resistant mutants of the Lyme disease agent, Borrelia burgdorferi. Mutations in parC, which encodes a subunit of topoisomerase IV, were associated with loss of susceptibility to sparfloxacin, moxifloxacin, and Bay-Y3118, but not ciprofloxacin. This is the first description of fluoroquinolone resistance in the spirochete phylum.

Characterization And Expression Analysis Of The Groesl Operon Of Bartonella Bacilliformis, Julie A. Callison, James M. Battisti, Kate N. Sappington, Laura S. Smitherman, Michael F. Minnick

Biological Sciences Faculty Publications

The groESL operon of Bartonella bacilliformis, a facultative intracellular, Gram-negative bacterium and etiologic agent of Oroya Fever, was characterized. Sequence analysis revealed an operon containing two genes of 294 (groES) and 1632 nucleotides (groEL) separated by a 55-nt intergenic spacer. The operon is preceded by a 72-nt ORF (ORF1) that encodes a hypothetical protein with homology to a portion of the HrcA repressor for groESL. A divergent fumarate hydratase C (fumC) gene lies further upstream. Deduced amino acid sequences for B. bacilliformis GroEL and GroES revealed a high degree of identity with homologues from other Bartonella and alpha-Protebacteria. A single …

Fisheries Occasional Publication No. 32 - Allocation Of The Western Australian Abalone Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to the Integrated Fisheries Allocation Advisory Committee (IFAAC), the Department will outline what it believes are the most practical and cost effective ways of managing a system for allocating the abalone resource between the commercial, customary and recreational sectors.

In preparing this submission, it has been noted that because of the limited data on recreational catch outside of the metropolitan area, the Sustainable Harvest Limit (SHL) set for the fishery relates only to the area that is equivalent to Area 7 of the commercial fishery. Further, it is acknowledged that the Minister has approved that proportional catch …

Efficacy Of Translocations For Restoring Populations Of Black-Tailed Prairie Dogs, Jo Ann L. D. Dullum, Kerry R. Foresman, Marc R. Matchett

United States Fish and Wildlife Service: Publications

We evaluated translocation as a method to promote recovery of black-tailed prairie dogs (Cynomys ludovicianus) after plague-induced population declines in colonies at the Charles M. Russell National Wildlife Refuge, Montana. We translocated prairie dogs in June of 1999 and evaluated the effects of translocation on colony area 1 year and 4 years later. We also assessed effects of release group size and estimated rates of population growth and survival. Initial size of experimental colonies was categorized as inactive (0 ha), small (0.1-2.0 ha), or large (2.0-6.6 ha); numbers of prairie dogs translocated to each colony size class were …

Managing Yaupon With Fire And Herbicides In The Texas Post Oak Savannah, Rob B. Mitchell, James C. Cathey, Brad Dabbert, Ron Sosebee, Dale F. Prochaska, Stephanie Dupree

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The Post Oak Savannah Ecological Region in Texas was once an open grassland savannah maintained by periodic fires. The Post Oak Savannah can support mid- and tall grasses, such as little bluestem, indiangrass, Texas wintergrass, and purpletop. Today, the savannahs have been replaced by oak woodlands with dense yaupon (Ilex vomitoria) understories that limit grass and forb production and species diversity (Fig. 1). Restriction of fires in conjunction with poor grazing management and periodic droughts are often credited for the dense thickets that occur in the Post Oak Savannah.

Yaupon is a native component of the Post Oak …

Biodemography Of A Long-Lived Tephritid: Reproduction And Longevity In A Large Cohort Of Female Mexican Fruit Flies, Anastrepha Ludens, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Damla Senturke, Lawrence G. Harshman

Lawrence G. Harshman Publications

Age of sexual maturity, daily and lifetime reproductive rates, and life span were recorded in a laboratory cohort of Mexican fruit flies consisting of over 1100 females maintained individually. The results revealed that, relative to the medfly, the Mexfly is slower maturing (14 vs 17 days), more fecund (1400 vs 650–1100 eggs/female), and longer lived (50 vs 35 days). The results reinforced the generality of several earlier findings on the medfly including the deceleration of mortality at older ages and the weakness of the correlation between the rate of egg laying at early ages and both subsequent reproduction and remaining …

Microcapsule Biosensors Based On Competitive Binding And Fluorescence Resonance Energy Transfer Assays, Swetha Chinnayelka

Doctoral Dissertations

Fluorescent sensing systems offer the potential for minimally invasive monitoring with implantable devices, but they require carrier technologies that provide suitable immobilization, accessibility, and biocompatibility while maintaining adequate response characteristics. Towards the development of this goal, a general design of a biosensor with the capability of detecting different metabolites was investigated. The approach is based on the encapsulation of a competitive binding assay in microcapsules and monitoring the changes in fluorescence resonance energy transfer (FRET) in the presence of analyte. To experimentally demonstrate this type of sensing system, glucose was chosen as the model target analyte. The design, fabrication, and …

Molt Strategies And Age Differences In Migration Timing Among Autumn Landbird Migrants In Southwestern Idaho, Jay D. Carlisle, Gregory S. Kaltenecker, David L. Swanson

Intermountain Bird Observatory Publications and Presentations

Intraspecific patterns of autumn migration timing are not well known, particularly in the western United States. Here, we (1) describe autumn migration timing and age ratios of landbird migrants in southwestern Idaho, (2) examine differences in timing among age and sex classes, and (3) demonstrate how prebasic molt strategies affect migration timing differences between age classes. As a group, Neotropical migrants were most common from late July through early September, whereas temperate migrants were most common from mid-September into early October. Proportion of hatch-year birds was 74.5% for all migrants combined and ranged from 33.3% to 100% for individual species. …

The Effect Of Human Predation, Rats And Goats On Small Colonies Of Wedge-Tailed Shearwaters (Puffinus Pacificus) In Southwest Madagascar, Alexis P. Will

Independent Study Project (ISP) Collection

Three islands: Betsiboko, Jamanjaky Be and Jamanjaky Roa, off the coast of Morombe in Southwest Madagascar were visited in November 2005 to verify the existence and evaluate the health of wedge-tailed shearwater (Puffinus pacificus) colonies that were described by Otto Appert in the 1960’s (Hawkins (a) 2005; Hawkins (b) 2005). These three islands experience varying degrees of human use, ranging from low: light human predation on shearwater chicks, to high: the presence of domestic animals, collecting fuelwood on the island and more intensive harvesting of chicks. Interviews were conducted with the local Vezo (fishing) people to quantify the human predation …

La Flore Qui A Faim : Une Enquête Chimique, Biologique Et Culturelle De La Dimorphisme Rouge/Verte Et Les Applications Médicinales De Nepenthes Madagascariensis, Keirnan Willett

Independent Study Project (ISP) Collection

Le Nepenthes madagascariensis est une plante carnivore endémique du côté sud-est de Madagascar qui attirent la proie arthropode (insectes, araignées etc.) en employant les bouts de feuilles convertis en forme des pichets ou urnes. Après d’être attiré par le suc au bord de l’urne, les insectes devint désorientés, perdent la traction et se coulent dans le liquide riche en enzymes digestifs au dessous (14). Les substances nutritives des cadavres sont absorbées par la plante en compensant pour la lacune d’azote dans le sol. Les couvercles des urnes expriment une couleur rouge ou verte. Notre étude examine les différences chimiques et …
