New Ommatius Wiedemann From The Americas With Two New Species Groups, Keys, And Taxonomic Notes (Diptera: Asilidae), Aubrey G. Scarbrough

Insecta Mundi

Two species groups are proposed for Ommatius Wiedemann, normus and tibialis species groups, increasing the number to eight groups from the Americas. The normus group includes six species, two of which are new, O. nebulosus n. sp. and O. tepui n. sp., from Venezuela. This species group thus far extends from Venezuela southward into Paraguay and southern Brazil. Ommatius pulcher (Engel) is redescribed and a neotype designated. The tibialis group includes eight previously described species from eastern and southwestern United States. Ommatius gemma Brimley is transferred to the costatus group. Keys to the eight species groups and the species of …

Highly Sensitive Mass Detection And Identification Using Vibration Localization In Coupled Microcantilever Arrays, Matthew A. Spletzer, Arvind Raman, Hartono Sumali, John P. Sullivan

Birck and NCN Publications

We study the use of vibration localization in large arrays of mechanically coupled, nearly identical microcantilevers for ultrasensitive mass detection and identification. We demonstrate that eigenmode changes in such an array can be two to three orders of magnitude greater than relative changes in resonance frequencies when an analyte mass is added. Moreover, the changes in eigenmodes are unique to the cantilever to which mass is added, thereby providing a characteristic "fingerprint" that identifies the particular cantilever where mass has been added. This opens the door to ultrasensitive detection and identification of multiple analytes with a single coupled array.

Mechanisms By Which Apoptotic Membranes Become Susceptible To Secretory Phospholipase A2, Rachel Williams Bailey

Theses and Dissertations

During apoptosis, changes occur in T-lymphocyte membranes that render them susceptible to hydrolysis by secretory phospholipase A2 (sPLA2). To study the relevant mechanisms, a simplified model of apoptosis using a calcium ionophore was first applied. Kinetic and flow cytometry experiments provided key observations regarding ionophore treatment: initial hydrolysis rate was elevated, total reaction product was increased four-fold, and adsorption of the enzyme to the membrane surface was unaltered. Analysis of these results suggested that susceptibility during calcium-induced apoptosis is limited by substrate availability rather than enzyme adsorption. Fluorescence experiments identified three membrane alterations that might affect substrate access to the …

Orchestration Of The S-Phase And Dna Damage Checkpoint Pathways By Replication Forks From Early Origins, Julie M. Caldwell, Yinhuai Chen, Kaila L. Schollaert, James F. Theis, George F. Babcock, Carol S. Newlon, Yolanda Sanchez

Dartmouth Scholarship

The S-phase checkpoint activated at replication forks coordinates DNA replication when forks stall because of DNA damage or low deoxyribonucleotide triphosphate pools. We explore the involvement of replication forks in coordinating the S-phase checkpoint using dun1Δ cells that have a defect in the number of stalled forks formed from early origins and are dependent on the DNA damage Chk1p pathway for survival when replication is stalled. We show that providing additional origins activated in early S phase and establishing a paused fork at a replication fork pause site restores S-phase checkpoint signaling to chk1Δ dun1Δ cells and relieves the reliance …

Securing Manets With Bitsi: Danger Theory And Mission Continuity, Marco Carvalho, Richard A. Ford, William H. Allen, Gerald A. Marin

Electrical Engineering and Computer Science Faculty Publications

MANET (Mobile Ad hoc Network) environments are becoming increasingly important as potential users recognize the benefits of being able to create a functional network using little or no fixed infrastructure. Unfortunately, the very properties that provide such flexibility also cause significant complications in terms of security. The collaborative nature of the system combined with its continual state of flux requires solutions that are highly dynamic, and that can adapt to massive changes in system resources, traffic patterns and network topology. In this paper, we outline a new approach to MANET security called BITSI (the Biologically-Inspired Tactical Security Infrastructure). BITSI is …

The Effects Of Prenatally Administered Phytoestrogens On The Reproductive And Behavioral Development Of Long-Evans Rats, Crystal Blake

Theses and Dissertations

Equol is known to be a selective androgen modulator and has the ability to bind and inhibit 5-alpha dihydrotestosterone (5α-DHT). Equol is also a selective estrogen receptor modulator and is able to bind beta estrogen receptors with high affinity. As estrogen receptors are found in the hypothalamus, pituitary, and gonads, prenatally administered equol could affect the morphological and reproductive development of offspring. To test this hypothesis, during gestational days 14 to 20, forty-two pregnant Long-Evans rats were given one of six treatments: 1) no treatment, 2) injection with dimethyl sulfoxide (DMSO), 3) injection with 10 mg/kg equol, 4) injection with …

Genetic Evidence For An Alternative Citrate-Dependent Biofilm Formation Pathway In Staphylococcus Aureus That Is Dependent On Fibronectin Binding Proteins And The Grars Two-Component Regulatory System, Robert M. Q. Shanks, Michael A. Meehl, Kimberly M. Brothers, Raquel M. Martinez, Niles P. Donegan, Martha L. Graber, Ambrose L. Cheung, George A. O'Toole

Dartmouth Scholarship

We reported previously that low concentrations of sodium citrate strongly promote biofilm formation by Staphylococcus aureus laboratory strains and clinical isolates. Here, we show that citrate promotes biofilm formation via stimulating both cell-to-surface and cell-to-cell interactions. Citrate-stimulated biofilm formation is independent of the ica locus, and in fact, citrate represses polysaccharide adhesin production. We show that fibronectin binding proteins FnbA and FnbB and the global regulator SarA, which positively regulates fnbA and fnbB gene expression, are required for citrate's positive effects on biofilm formation, and citrate also stimulates fnbA and fnbB gene expression. Biofilm formation is also stimulated by several …

A Constant Struggle: Renegotiating Identity In The Aftermath Of Rape, Jo Aine Clarke

USF Tampa Graduate Theses and Dissertations

The academic study of rape has historically ignored the recovery experience of the person being raped. Beyond medical and physical effects, and the possibility of legal prosecution, little attention has been paid. Existing research loses sight of the survivor's experience, ignoring the fact that a rape affects every aspect of life. The trauma is not only physical, but also impinges on the emotional, intellectual and interpersonal spheres. Rape can be, and often is, a life-threatening experience: one that needs to be faced and dealt with before there can be any sort of productive future. While it has been demonstrated that …

Electrochemical Durability Of Carbon Nanotubes At 80 °C, Liang Li, Yangchuan Xing

Chemical and Biochemical Engineering Faculty Research & Creative Works

Carbon nanotubes (CNTs) have been studied as an alternative catalyst support in polymer electrolyte membrane (PEM) fuel cells. Recent studies showed that CNTs appear to be more resistant to electrochemical corrosion than carbon black (CB). in a previous study, we have demonstrated the room temperature durability of multiwalled CNTs in both non-catalyzed and catalyzed electrochemical oxidations. This paper is to report results conducted at 80 °C-an operational temperature of PEM fuel cells. It was found that multiwalled CNTs are still more resistant than CB at the elevated temperature. However, the electrochemical oxidation rate is more rapid than that at the …

Synthesis And In Vitro Properties Of Trimethylamine- And Phosphonate-Substituted Carboranylporphyrins For Application In Bnct, Michael W. Easson, Frank R. Fronczek, Timothy J. Jensen, M. Graça H. Vicente

Faculty Publications

A series of carboranylporphyrins containing either amine or phosphonic acid functionalities and two to six closo-carborane clusters have been synthesized via a [2 + 2] condensation of a dimethylamino- or diethylphosphonate-substituted dipyrromethane with a dicarboranylmethyl-benzaldehyde. The X-ray structures of four key reaction intermediates (1, 2, 3, and 4a) and of two target porphyrins, the diphosphonate ester- and the diamino-tetracarboranylporphyrins 5b and 6a, are presented and discussed. In vitro studies using human carcinoma HEp2 and human glioblastoma T98G cells show that these porphyrins are non-toxic in the dark up to 100 μM concentrations, and that a tetracarboranylporphyrin bearing two quaternary ammonium …

Eco-Social Analysis Of An East African Agro-Pastoral System: Management Of Tsetse And Bovine Trypanosomiasis, Johann Baumgärtner, Gianni Gilioli, Getachew Tikubet, Andrew Paul Gutierrez

All Peer-Reviewed Publications

A key constraint for development of many East African agro-pastoral communities is African animal trypanosomiasis or nagana caused by Trypanosoma spp. and vectored by species of tsetse flies (Glossina spp.). Suppression of trypanosomiasis through trapping of tsetse fly populations was conducted from 1995 to 2005 at and near Luke, Southwest Ethiopia. Odor baited mass trapping technology was used to suppress adult fly populations to very low levels while tryponocidal drugs were used to treat trypanosome infections in cattle. Data on ecological, economic and social variables were collected and analyzed in the context of eco-social dynamics in the community. The bio-economic …
