How Might Ecologists Make The World Safe For Biodiversity Without Getting Fired?, David Johns Dec 2012

How Might Ecologists Make The World Safe For Biodiversity Without Getting Fired?, David Johns

Political Science Faculty Publications and Presentations

This essay raises the following questions: What if conservation success depends less on speaking truth to power than on organizing a political force that can bring more pressure to bear on decision makers than their opponents? But what if natural scientists, by virtue of their knowledge, passion, commitment, are pretty much the only group that can be trusted with the fate of biodiversity and leading humankind out of their destructive ways? What if begging policy makers to do the right thing means barren oceans, the end of many species, and the end of wild places (not to mention a more …

A New Species Of Molinema (Nematoda: Onchocercidae) In Bolivian Rodents And Emended Description Of Litomosoides Esslingeri Bain, Petit, And Diagne, 1989., Juliana Notarnicola, F Agustin Jimenez-Ruiz, Scott L Gardner

Publications

We report the distribution of 2 species of filarioid nematodes occurring in different hosts in the central region of South America. Molinema boliviensis n. sp. was recorded as a parasite of sigmodontine and echymyid rodents in Bolivia, and Litomosoides esslingeri was recorded in sigmodontine and ctenomyid rodents from Bolivia and Argentina. Molinema boliviensis n. sp. shares several similarities with other species reported in spiny rats; however, it can be easily differentiated by the presence of a flat anterior end, gradually tapering lappets and a tubercle present in posterior end, a short, uniform buccal capsule, an oval-shaped vagina vera, and a …

Studies On Spreading Depolarization In Healthy And Metabolically Compromised Brain Tissues, Isamu Aiba Dec 2012

Studies On Spreading Depolarization In Healthy And Metabolically Compromised Brain Tissues, Isamu Aiba

Biomedical Sciences ETDs

Spreading depolarization (SD) is a slowly propagating wave of depolarization of neurons and glia. Since its original discovery in 1944, SD has been observed in various experimental settings, both in vitro and in vivo. SD has recently been detected in brains of human patients with various injuries, and a contribution of SD to deleterious consequences of acute brain injury is increasingly accepted. iv The present dissertation work focus mainly on the characterization of SD and cellular events associated with it. Main interests of these studies are on underlying mechanisms that convert non-injurious factors into mediators of acute neuronal injury. One …

Prenatal Alcohol Exposure Alters Histamine H3 Receptor Modulation Of Glutamate Release And Long-Term Potentiation In The Rat Dentate Gyrus, Rafael Koerich Varaschin Dec 2012

Prenatal Alcohol Exposure Alters Histamine H3 Receptor Modulation Of Glutamate Release And Long-Term Potentiation In The Rat Dentate Gyrus, Rafael Koerich Varaschin

Biomedical Sciences ETDs

Children with Fetal Alcohol Spectrum Disorder exhibit long lasting behavioral impairments, such as learning disabilities, problems in executive functioning and memory deficits. Currently, there are no rationally designed, clinically available pharmacological tools to circumvent prenatal alcohol-induced cognitive deficits. Recently, using a rat model of voluntary drinking during pregnancy, Savage and collaborators (2010) showed that the inverse agonist of histamine H3 receptors reverses fetal ethanol-induced deficits in learning and memory, without further increasing cognition in control rats. These differential effects and the notion that H3 receptors reside in presynaptic nerve terminals to inhibit neurotransmitter release, led to the hypothesis that fetal …

Effect Of Scc Mixture Composition On Thixotropy And Formwork Pressure, A. F. Omran, Kamal H. Khayat, Y. M. Elaguab Dec 2012

Effect Of Scc Mixture Composition On Thixotropy And Formwork Pressure, A. F. Omran, Kamal H. Khayat, Y. M. Elaguab

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

High lateral pressure exerted on formwork systems by self-consolidating concrete (SCC) is one of the hindrances for using such highly flowable concrete in cast-in-place applications. Self-consolidating concrete is a complex system that can be made using a wide range of mixture proportioning and often incorporated various chemical admixtures and supplementary cementitious materials. the investigation of the effect of each material ingredient independently on lateral pressure of SCC is not a simple task. in this study, thixotropy is rather used to assess the effect of various mixture parameters on formwork pressure. Thixotropy is determined by the evaluation of the structural buildup …

Reframing The Mediation Lens: The Call For A Situational Style Of Mediation, Tanya M. Marcum, Charles R. Stoner, Sandra J. Perry

Southern Illinois University Law Journal

Child custody mediation can have a positive impact on the parties involved in mediation as well as on the process of settlement itself.  The process of mediation focuses the parties on the needs of the children and helps the parents to be realistic in their expectations regarding custody and visitation of the children.  Mediators realize the importance of listening carefully to the parties involved in the custody dispute.  This article looks at three distinct groups of mediators involved in child custody mediation in the state of Illinois, the mediators perceived mediation styles, and their actual mediation styles.  As a result, …

Performance Of Polar Codes For Quantum And Private Classical Communication, Zachary Dutton, Saikat Guha, Mark M. Wilde Dec 2012

Performance Of Polar Codes For Quantum And Private Classical Communication, Zachary Dutton, Saikat Guha, Mark M. Wilde

Faculty Publications

We analyze the practical performance of quantum polar codes, by computing rigorous bounds on block error probability and by numerically simulating them. We evaluate our bounds for quantum erasure channels with coding block lengths between 210 and 220, and we report the results of simulations for quantum erasure channels, quantum depolarizing channels, and 'BB84' channels with coding block lengths up to N = 1024. For quantum erasure channels, we observe that high quantum data rates can be achieved for block error rates Pe ≤ 10-4 and that somewhat lower quantum data rates can be achieved for quantum depolarizing and BB84 …

Public And Private Resource Trade-Offs For A Quantum Channel, Mark M. Wilde, Min Hsiu Hsieh Dec 2012

Public And Private Resource Trade-Offs For A Quantum Channel, Mark M. Wilde, Min Hsiu Hsieh

Faculty Publications

Collins and Popescu realized a powerful analogy between several resources in classical and quantum information theory. The Collins-Popescu analogy states that public classical communication, private classical communication, and secret key interact with one another somewhat similarly to the way that classical communication, quantum communication, and entanglement interact. This paper discusses the information-theoretic treatment of this analogy for the case of noisy quantum channels. We determine a capacity region for a quantum channel interacting with the noiseless resources of public classical communication, private classical communication, and secret key. We then compare this region with the classical-quantum-entanglement region from our prior efforts …

A thorough search for large-scale anisotropies in the distribution of arrival directions of cosmic rays detected above 1018eV at the Pierre Auger Observatory is presented. This search is performed as a function of both declination and right ascension in several energy ranges above 10 18eV, and reported in terms of dipolar and quadrupolar coefficients. Within the systematic uncertainties, no significant deviation from isotropy is revealed. Assuming that any cosmic-ray anisotropy is dominated by dipole and quadrupole moments in this energy range, upper limits on their amplitudes are derived. These upper limits allow us to test the origin of cosmic rays …

Brown dwarfs are important objects because they may provide a missing link between stars and planets, two populations that have dramatically different formation histories. In this paper, we present the candidate binaries with brown dwarf companions that are found by analyzing binary microlensing events discovered during the 2004-2011 observation seasons. Based on the low mass ratio criterion of q < 0.2, we found seven candidate events: OGLE-2004-BLG-035, OGLE-2004-BLG-039, OGLE-2007-BLG-006, OGLE-2007-BLG-399/MOA-2007-BLG-334, MOA-2011-BLG-104/OGLE-2011-BLG-0172, MOA-2011-BLG-149, and MOA-201-BLG-278/OGLE- 2011-BLG-012N. Among them, we are able to confirm that the companions of the lenses of MOA-2011-BLG-104/OGLE-2011-BLG-0172 and MOA-2011-BLG-149 are brown dwarfs by determining the mass of the lens based on the simultaneous measurement of the Einstein radius and the lens parallax. The measured masses of the brown dwarf companions are 0.02 ± 0.01 M and 0.019 ± 0.002 M for MOA-2011-BLG-104/OGLE-2011-BLG-0172 and MOA-2011-BLG-149, respectively, and both companions are orbiting low-mass M dwarf host stars. More microlensing brown dwarfs are expected to be detected as the number of lensing events with well-covered light curves increases with new-generation searches. © 2012.

Precise measurement of neutrino beam direction and intensity was achieved based on a new concept with modularized neutrino detectors. INGRID (Interactive Neutrino GRID) is an on-axis near detector for the T2K long baseline neutrino oscillation experiment. INGRID consists of 16 identical modules arranged in horizontal and vertical arrays around the beam center. The module has a sandwich structure of iron target plates and scintillator trackers. INGRID directly monitors the muon neutrino beam profile center and intensity using the number of observed neutrino events in each module. The neutrino beam direction is measured with accuracy better than 0.4 mrad from the …

A thorough search of the sky exposed at the Pierre Auger Cosmic Ray Observatory reveals no statistically significant excess of events in any small solid angle that would be indicative of a flux of neutral particles from a discrete source. The search covers from -90° to +15° in declination using four different energy ranges above 1 EeV (1018 eV). The method used in this search is more sensitive to neutrons than to photons. The upper limit on a neutron flux is derived for a dense grid of directions for each of the four energy ranges. These results constrain scenarios for …

We present the first multi-wavelength follow-up observations of two candidate gravitational-wave (GW) transient events recorded by LIGO and Virgo in their 2009-2010 science run. The events were selected with low latency by the network of GW detectors (within less than 10 minutes) and their candidate sky locations were observed by the Swift observatory (within 12 hr). Image transient detection was used to analyze the collected electromagnetic data, which were found to be consistent with background. Off-line analysis of the GW data alone has also established that the selected GW events show no evidence of an astrophysical origin; one of them …

Syntheses And Photodynamic Activity Of Pegylated Cationic Zn(Ii)-Phthalocyanines In Hep2 Cells, Benson G. Ongarora, Xiaoke Hu, Susan D. Verberne-Sutton, Jayne C. Garno, M. Graça H. Vicente

Faculty Publications

Di-cationic Zn(II)-phthalocyanines (ZnPcs) are promising photosensitizers for the photody-namic therapy (PDT) of cancers and for photoinactivation of viruses and bacteria. Pegylation of photosensitizers in general enhances their water-solubility and tumor cell accumulation. A series of pegylated di-cationic ZnPcs were synthesized from conjugation of a low molecular weight PEG group to a pre-formed Pc macrocycle, or by mixed condensation involving a pegylated phthalonitrile. All pegylated ZnPcs were highly soluble in polar organic solvents but were insoluble in water; they have intense Q absorptions centered at 680 nm and fluores-cence quantum yields of ca. 0.2 in DMF. The non-pegylated di-cationic ZnPc 6a …

Analysis Of Composition And Structure Of Coastal To Mesopelagic Bacterioplankton Communities In The Northern Gulf Of Mexico, Gary M. King, Conor B. Smith, Bradley Tolar, James T. Hollibaugh Dec 2012

Analysis Of Composition And Structure Of Coastal To Mesopelagic Bacterioplankton Communities In The Northern Gulf Of Mexico, Gary M. King, Conor B. Smith, Bradley Tolar, James T. Hollibaugh

Faculty Publications

16S rRNA gene amplicons were pyrosequenced to assess bacterioplankton community composition, diversity, and phylogenetic community structure for 17 stations in the northern Gulf of Mexico (nGoM) sampled in March 2010. Statistical analyses showed that sam ples from depths ≤100 m differed distinctly from deeper samples. SAR 11 α-Proteobacteria and Bacteroidetes dominated communities at depths ≤100 m, which were characterized by high α-Proteobacteria/γ-Proteobacteria ratios (α/γ > 1.7). Thaumarchaeota, Firmicutes, and δ-Proteobacteria were relatively abundant in deeper waters, and α/γ ratios were low (<1). Canonical correlation analysis indicated that δ- and γ-Proteobacteria,Thaumarchaeota, and Firmicutes correlated positively with depth; α-Proteobacteria and Bacteroidetes correlated positively with temperature and dissolved oxygen; Actinobacteria, β-Proteobacteria, and Verrucomicrobia correlated positively with a measure of suspended particles. Diversity indices did not vary with depth or other factors, which indicated that richness and evenness elements of bacterioplankton communities might develop independently of nGoM physical-chemical variables. Phylogenetic community structure as measured by the net relatedness (NRI) and nearest taxon (NTI) indices also did not vary with depth. NRI values indicated that most of the communities were comprised of OTUs more distantly related to each other in whole community comparisons than expected by chance. NTI values derived from phylogenetic distances of the closest neighbor for each OTU in a given community indicated that OTUs tended to occur in clusters to a greater extent than expected by chance. This indicates that "habitat filtering" might play an important role in nGoM bacterioplankton species assembly, and that such filtering occurs throughout the water column.© 2013 King, Smith, Tolar and Hollibaugh.

Competition Of Zinc Ion For The [2fe-2s] Cluster Binding Site In The Diabetes Drug Target Protein Mitoneet, Guoqiang Tan, Aaron P. Landry, Ruili Dai, Li Wang, Jianxin Lu, Huangen Ding

Faculty Publications

Human mitochondrial protein mitoNEET is a novel target of type II diabetes drug pioglitazone, and contains a redox active [2Fe-2S] cluster that is hosted by a unique ligand arrangement of three cysteine and one histidine residues. Here we report that zinc ion can compete for the [2Fe-2S] cluster binding site in human mitoNEET and potentially modulate the physiological function of mitoNEET. When recombinant mitoNEET is expressed in Escherichia coli cells grown in M9 minimal media, purified mitoNEET contains very little or no iron-sulfur clusters. Addition of exogenous iron or zinc ion in the media produces mitoNEET bound with a [2Fe-2S] …

Efficacy Of Foliar Insecticides On Eggs Of Nezara Viridula (Hemiptera: Pentatomidae), Sebe A. Brown, Jeffrey A. Davis, Arthur R. Richter

Faculty Publications

Stink bugs (Hemiptera: Pentatomidae) are important insect pests of crops. Stink bug feeding reduces yields, lowers crop quality, induces delayed maturity, and wounds tissues allowing for pathogen entry. Historically, effective adult and nymph control of stink bugs has been with insecticides. However, little insecticide efficacy against stink bug eggs is known. The objective of this study was to determine how foliar insecticides currently recommend for southern green stink bug, Nezara viridula (L.), control in soybean impact pre-emergence nymphal mortality using an egg dip bioassay. Eight formulate insecticides were tested. Differences in nymphal stink bug pre-emergence mortality were recorded. The lowest …

A three-treatment aerial application insecticide experiment was conducted in five commercial sugarcane, Saccharum spp., fields in south Texas to evaluate the use of pheromone traps for improving chemical control of the Mexican rice borer, Eoreuma loftini (Dyar), in 2009 and 2010. A threshold of 20 moths/trap/wk was used to initiate monitoring for larval infestations. The percentage of stalks with larvae on plant surfaces was directly related to the number of moths trapped. Reductions in borer injury and adult emergence were detected when a threshold of >5% of stalks with larvae present on plant surfaces was used to trigger insecticide applications. …

Using two-dimensional foraging arenas, laboratory tests were conducted to investigate the effect of soil type, soil moisture level and ambient temperature on the exploratory tunneling by Coptotermes formosanus Shiraki. In choice arenas consisting of two substrate types having two moisture levels each, and conducted at a constant temperature of 22 °C, a significantly greater proportion of termites aggregated in sand than in sandy loam. Similarly, the length of excavated tunnels was also increased in sand. In a given substrate, termite aggregation or tunnel length did not differ between 5% and 15% moisture levels. In no-choice tests, where three different substrates …

Transgenic corn (Zea mays L.) products expressing multiple Bt proteins targeting a same group of insect pests have become commercially available in the U.S. The first commercialized pyramided Bt corn technologies for managing lepidopteran pests include Genuity® VT Triple Pro™ and Genuity® SmartStax™. In this study, larval survival and plant injury of Cry1Ab-susceptible (Cry1Ab-SS), -resistant (Cry1Ab-RR), and -heterozygous (Cry1Ab-RS) genotypes of the sugarcane borer, Diatraea saccharalis F., on five commercial corn hybrids were evaluated in a leaf tissue bioassay and two greenhouse trials during 2010-2011. The five hybrids included two non-Bt corn and three Bt corn hybrids representing three transgenic …
