Russia And Arms Control: Are There Opportunities For The Obama Administration?, Stephen J. Blank Dr.

Books, Monographs & Collaborative Studies

Russo-American relations are generally acknowledged to be at an impasse. Arms control issues feature prominently in that conflicted agenda. Indeed, as of September 2008, the Bush administration was contemplating not just a break in arms talks but actual sanctions, and allowed the bilateral civil nuclear treaty with Russia to die in the Senate rather than go forward for confirmation. Russian spokesmen make clear their belief that American concessions on key elements of arms control issues like missile defenses in Europe are a touchstone for the relationship and a condition of any further progress towards genuine dialogue. This impasse poses several …

Biarsenical Labeling Of Vesicular Stomatitis Virus Encoding Tetracysteine-Tagged M Protein Allows Dynamic Imaging Of M Protein And Virus Uncoating In Infected Cells, Subash C. Das, Debasis Panda, Debasis Nayak, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

A recombinant vesicular stomatitis virus (VSV-PeGFP-M-MmRFP) encoding enhanced green fluorescent protein fused in frame with P (PeGFP) in place of P and a fusion matrix protein (monomeric red fluorescent protein fused in frame at the carboxy terminus of M [MmRFP]) at the G-L gene junction, in addition to wild-type (wt) M protein in its normal location, was recovered, but the MmRFP was not incorporated into the virions. Subsequently, we generated recombinant viruses (VSV-PeGFP-∆M-Mtc and VSV-∆M-Mtc) encoding Mprotein with a carboxy-terminal tetracysteine tag (Mtc) in place of the M protein. These recombinant viruses incorporated Mtc at levels similar to M in …

Synthesis And Characterization Of Hazelnut Oil-Based Biodiesel, Yixiang Xu, Milford Hanna

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The demand for diesel fuel far exceeds the current and future biodiesel production capabilities of the vegetable oil and animal fat industries. New oilseed crops that do not compete with traditional food crop are needed to meet existing energy demands. Hybrid hazelnut oil is just such an attractive raw material for production of biodiesel. Hazelnut oil was extracted from hybrid hazelnuts and the crude oil was refined. Hazelnut oil-based biodiesel was prepared via the transesterification of the refined hazelnut oil with excess methanol using an alkaline catalyst. The effects of reaction temperature, time and catalyst concentration on the yield of …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Adsorption and desorption of phosphorus (P) and nitrogen (N) by stalk residues may influence the concentrations of P and N in runoff. A laboratory study was conducted to measure the effects of P and N constituents in solution on adsorption and desorption of P and N by corn, soybean, and wheat stalk residues. Experimental variables included type of stalk material (corn, soybean, and wheat), inorganic nutrients in solution (PO₄-P and NO₃-N; PO₄-P and NH₄-N; NO₃-N and NH₄-N; and PO₄-P, NO₃-N, and NH₄-N), …

Thermodynamically Coupled Heat And Mass Flows In A Reaction-Transport System With External Resistances, Yaşar Demirel

Yaşar Demirel Publications

Considerable work has been published on mathematically coupled nonlinear differential equations by neglecting thermodynamic coupling between heat and mass flows in reaction-transport systems. The thermodynamic coupling refers that a flow occurs without or against its primary thermodynamic driving force, which may be a gradient of temperature, or chemical potential, or reaction affinity. This study presents the modeling of thermodynamically coupled heat and mass flows of two components in a reaction-transport system with external heat and mass transfer resistances. The modeling equations are based on the linear nonequilibrium thermodynamics approach by assuming that the system is in the vicinity of global …

Why We Have Field Stations: Reflections On The Cultivation Of Biologists, John J. Janovy Jr., Krista M. Major

John J. Janovy, Jr. Publications

For a resident of the state of Nebraska, the Cedar Point Biological Station (CPBS), located in scenic limestone bluffs below Kingsley Dam, an earth-filled artificial mountain that impounds a lake 35 kilometers long and 5 kilometers wide, is a bargain in American higher education. In three weeks a student can earn four credits of upper-division coursework, get original research experience, and, most importantly—especially in an educational milieu increasingly characterized by electronic content and electronic course management—get his or her hands on some live wild plants and animals in an appropriate ecological context. This encounter with nature is typically the first …

Wnt And Egf Pathways Act Together To Induce C. Elegans Male Hook Development, Hui Yu, Adeline Seah, Michael A. Herman, Edwin L. Ferguson, H. Robert Horvitz, Paul W. Sternberg

School of Biological Sciences: Faculty Publications

Comparative studies of vulva development between Caenorhabditis elegans and other nematode species have provided some insight into the evolution of patterning networks. However, molecular genetic details are available only in C. elegans and Pristionchus pacificus. To extend our knowledge on the evolution of patterning networks, we studied the C. elegans male hook competence group (HCG), an equivalence group that has similar developmental origins to the vulval precursor cells (VPCs), which generate the vulva in the hermaphrodite. Similar to VPC fate specification, each HCG cell adopts one of three fates (1°, 2°, 3°), and 2° HCG fate specification …

From Cells To Coastlines: How Can We Use Physiology To Forecast The Impacts Of Climate Change?, Brian Helmuth

Faculty Publications

The interdisciplinary fields of conservation physiology, macrophysiology, and mechanistic ecological forecasting have recently emerged as means of integrating detailed physiological responses to the broader questions of ecological and evolutionary responses to global climate change. Bridging the gap between large-scale records of weather and climate (as measured by remote sensing platforms, buoys and ground-based weather stations) and the physical world as experienced by organisms (niche-level measurements) requires a mechanistic understanding of how ‘environmental signals’ (parameters such as air, surface and water temperature, food availability, water flow) are translated into signals at the scale of the organism or cell (e.g. body temperature, …

Web Query Recommendation Via Sequential Query Prediction, Qi He, Daxin Jiang, Zhen Liao, Steven C. H. Hoi, Kuiyu Chang, Ee Peng Lim, Hang Li

Research Collection School Of Computing and Information Systems

Web query recommendation has long been considered a key feature of search engines. Building a good Web query recommendation system, however, is very difficult due to the fundamental challenge of predicting users' search intent, especially given the limited user context information. In this paper, we propose a novel "sequential query prediction" approach that tries to grasp a user's search intent based on his/her past query sequence and its resemblance to historical query sequence models mined from massive search engine logs. Different query sequence models were examined, including the naive variable length N-gram model, Variable Memory Markov (VMM) model, and our …

Molecular Dynamics Study Of Crystal Plasticity During Nanoindentation In Ni Nanowires, V. Dupont, F. Sansoz

Aerospace Engineering - Daytona Beach

Molecular dynamics simulations were performed to gain fundamental insight into crystal plasticity, and its size effects in nanowires deformed by spherical indentation. This work focused on-oriented single-crystal, defect-free Ni nanowires of cylindrical shape with diameters of 12 and 30 nm. The indentation of thin films was also comparatively studied to characterize the influence of free surfaces in the emission and absorption of lattice dislocations in single-crystal Ni. All of the simulations were conducted at 300 K by using a virtual spherical indenter of 18 nm in diameter with a displacement rate of1 ms1. No significant effect of sample size was …

Granite Rock Outcrops: An Extreme Environment For Soil Nematodes?, Erin Austin, Katharine Semmens, Charles Parsons, Amy M. Treonis

Biology Faculty Publications

We studied soil nematode communities from the surface of granite flatrock outcrops in the eastern Piedmont region of the United States. The thin soils that develop here experience high light intensity and extreme fluctuations in temperature and moisture and host unique plant communities. We collected soils from outcrop microsites in Virginia (VA) and North Carolina (NC) in various stages of succession (Primitive, Minimal, and Mature) and compared soil properties and nematode communities to those of adjacent forest soils. Nematodes were present in most outcrop soils, with densities comparable to forest soils (P > 0.05). Nematode communities in Mature and Minimal soils …

To Emit Is Human; To Regulate, Divine: Statutory Interpretation Of The Clean Air Act In Massachusetts V. Environmental Protection Agency, 127 S. Ct. 1438 (2007), Kathryn Hurie

Southern Illinois University Law Journal

Whether global warming is scientific fact or mere conjecture, Massachusetts v. Environmental Protection Agency is the quintessential case regarding the future of air pollution regulation. In this case, the Supreme Court held that the Environmental Protection Agency must make a ruling as to whether carbon dioxide and other greenhouse gases constitute air pollutants. If so, the Clean Air Act requires the EPA to regulate emissions of such gases from new motor vehicles. If not, the EPA can avoid regulation of such emissions. 
Regardless of its findings, the EPA can no longer refuse to make a determination. This Casenote argues carbon …

The parameters studied included temperature (ambient, 20, 25 and 30°C), exposure time (up to 30 min), gas flow rate (0·03, 0·06, 0·12, 0·25, 0·5 and 0·75 l min−1) and concentration level (five different levels). The efficacy of ozone treatment was a function of the parameters investigated and optimum control parameters of flow rate (0·12 l min−1), temperature (ambient) and ozone concentration (75 μg ml−1) resulted …

Thermodynamics Of Effector Binding To Hemocyanin : Influence Of Temperature., Ariane Pott, Michael Menze, Manfred Grieshaber

Faculty and Staff Scholarship

Hemocyanins are allosterically regulated oxygen carriers freely dissolved in the blood of many crustaceans. The natural modulator urate accumulates under hypoxic conditions in the hemolymph of Homarus vulgaris, and increases the oxygen affinity of the respiratory pigment. Other non-physiological effectors such as caffeine, dimethylxanthines and methylxanthines are also known to modulate the oxygen-binding properties of hemocyanin. In order to gain insight into the thermodynamic driving forces of these interactions we analyzed the binding of several urate analogs to dodecameric hemocyanin at different temperatures by employing isothermal titration calorimetry (ITC). All investigated non-physiological effectors including caffeine, dimethylxanthines and methylxanthines bind exothermically …

Efficacy Of Botanical And Mineral Oils On Willamette Mite (Acari: Tetranychidae), Elizabeth Ruby Begonia Church

Master's Theses

Willamette mite (WM), Eotetranychus willamettei, is a major pest throughout most winegrape regions in coastal California and Oregon. These mites puncture leaf tissue with their chelicerae and cause loss of photosynthetically active area. Chemical control treatments on grape include nearly ten registered synthetic miticides, plus soaps and oils. Oils can be petroleum based (mineral oil) or botanical (from seeds of various plants). There has been a lot of interest of late in the use of botanical oils other than soybean, including those derived from the seeds of plants including spearmint, rosemary and clove. This project tested for differences in the …

A large-scale mesocosm study was conducted to determine if vegetation with willow trees enhances biodegradation and to evaluate the mechanisms of natural biodegradation of weathered petroleum compounds under field conditions. The mesocosms were designed to model conditions at a former oil field where mid-range petroleum distillates were used as a diluent for pumping crude oil contaminated the soil and groundwater at the site with petroleum compounds. Ten mesocosms were constructed at the field site using un-impacted soil and diluent-impacted groundwater from the site. Five …

Examining The Relationship Between Religious Coping Strategies, Attachment Beliefs And Emotion Regulation In A Mixed Sample Of College Students Attending An Evangelical University In Central Virginia, Kevin C. Corsini

Doctoral Dissertations and Projects

Emotion regulation is an essential component of individual development, enabling a person to experience, recognize, express and modulate his emotions. There are a number of factors which influence the development of emotion regulation, including family context, biology, and primary caregiver interaction. Attachment theory provides a theoretical framework for describing these developmental influences and the resulting emotion regulation strategies an individual employs. Primary emotion regulation strategies are developed and utilized when an individual has established a secure attachment with his primary caregiver. When these secure attachments do not develop in the primary caregiver relationship, the resulting insecure attachment relationship leads the …

Elevated P21-Activated Kinase 2 Activity Results In Anchorage-Independent Growth And Resistance To Anticancer Drug-Induced Cell Death, Jerry Marlin, Andrew Eaton, Gerald Montano, Yu-Wen E. Chang, Rolf Jakobi

Student Publications

p21-activated kinase 2 (PAK-2) seems to be a regulatory switch between cell survival and cell death signaling. We have shown previously that activation of full-length PAK-2 by Rac or Cdc42 stimulates cell survival, whereas caspase activation of PAK-2 to the proapoptotic PAK-2p34 fragment is involved in the cell death response. In this study, we present a role of elevated activity of full-length PAK-2 in anchorage-independent growth and resistance to anticancer drug-induced apoptosis of cancer cells. Hs578T human breast cancer cells that have low levels of PAK-2 activity were more sensitive to anticancer drug-induced apoptosis and showed higher levels of caspase …
