How Does A Riverine Setting Affect The Lifestyle Of Shellmound Builders In Brazil?, Sabine Eggers, C. C. Petronilho, K. Brandt, C. Jericó-Daminello, J. Filippini, Karl Reinhard

Karl Reinhard Publications

The contact of inland and coastal prehistoric groups in Brazil is believed to have been restricted to regions with no geographical barrier, as is the case in the Ribeira de Iguape valley. The inland osteological collection from the riverine shellmound Moraes (5800–4500 BP) represents a unique opportunity to test this assumption for this region. Despite cultural similarities between riverine and coastal shellmounds, important ecological and site distribution differences are expected to impact on lifestyle. The purpose of this study is thus to document and interpret health and lifestyle indicators in Moraes in comparison to coastal shellmound groups. Specifically we test …

Objectives—Recent advances in the design of MRI contrast agents have rendered the lanthanide complexes of DOTA-tetraamide ligands of considerable interest, both as responsive MR agents and paramagnetic chemical exchange saturation transfer agents. The potential utility of these complexes for in vivo applications is contingent upon them being well tolerated by the body. The purpose of this study was to examine how the nature of the amide substituent, and in particular its charge, affected the fate of these chelates postinjection.

Materials and Methods—Complexes of 6 DOTA-tetraamide ligands were prepared in which the nature of the amide substituent was systematically …

Protecting Critical Infrastructure With Games Technology, Adrian Boeing, Martin Masek, Bill Bailey

Australian Information Warfare and Security Conference

It is widely recognised that there is a considerable gap in the protection of the national infrastructure. Trying to identify what is in fact ‘critical’ is proving to be very difficult as threats constantly evolve. An interactive prototyping tool is useful in playing out scenarios and simulating the effect of change, however existing simulators in the critical infrastructure area are typically limited in the visual representation and interactivity. To remedy this we propose the use of games technology. Through its use, critical infrastructure scenarios can be rapidly constructed, tested, and refined. In this paper, we highlight the features of games …

Measuring And Modeling Of Plant Root Uptake Of Organic Chemicals, Erik Dettenmaier

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Determining the root uptake of xenobiotic organic chemicals into plants is critical for assessing the human and ecological health risks associated with the consumption of plants growing in contaminated environments. Root uptake of xenobiotic organics occurs passively in conjunction with transpiration and the transport from root to shoot is ultimately controlled by passage through one or more lipid root membranes. The transpiration stream concentration factor (TSCF), the ratio between the concentration of a chemical in the xylem to that in the solution used by the roots, is used to describe the relative ability of an organic chemical to be passively …

Ibsen’S Female Characters In Captivity: An Exploration Of Literature And Performance, Christina K. Forshey

Senior Honors Theses

In Henrik Ibsen’s plays, A Doll’s House, The Wild Duck, The Lady from the Sea, and Hedda Gabler, the theme of captivity is demonstrated in the female protagonists Nora, Hedvig, Ellida, and Hedda. The theme of captivity also serves as a performance guide for the portrayal of these characters. Ibsen’s female protagonists are in bondage to an object or person that manipulates the character’s mental and emotional senses. The character’s inner captivity reaches a climax where a decision must be made to abolish the chains of captivity or forever remain enslaved. Since the nineteenth century, the actor has greatly benefitted …

Biogeography-Based Optimization, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

Biogeography is the study of the geographical distribution of biological organisms. Mathematical equations that govern the distribution of organisms were first discovered and developed during the 1960s. The mindset of the engineer is that we can learn from nature. This motivates the application of biogeography to optimization problems. Just as the mathematics of biological genetics inspired the development of genetic algorithms (GAs), and the mathematics of biological neurons inspired the development of artificial neural networks, this paper considers the mathematics of biogeography as the basis for the development of a new field: biogeography-based optimization (BBO). We discuss natural biogeography and …

Climate Change And Consumption, Michael P. Vandenbergh, Douglas A. Kysar

Vanderbilt Law School Faculty Publications

To achieve the level of greenhouse gas emissions reductions called for by climate change experts, officials and policy analysts may need to develop an unfamiliar category of regulated entity: the consumer. Although industrial, manufacturing, retail, and service sector firms undoubtedly will remain the focus of climate change policy in the near term, individuals and households exert a greenhouse footprint that seems simply too large for policymakers to ignore in the long term. This paper, written as a foreword for the Environmental Law Reporter's symposium issue, "Climate Change and Consumption," emerges from an interdisciplinary conference of the same title held at …

Retinoid X Receptor And Peroxisome Proliferator-Activated Receptor-Gamma Agonists Cooperate To Inhibit Matrix Metalloproteinase Gene Expression, Peter S. Burrage, Adam C. Schmucker, Yanqing Ren, Michael B. Sporn, Constance E. Brinckerhoff

Dartmouth Scholarship

We recently described the ability of retinoid X receptor (RXR) ligand LG100268 (LG268) to inhibit interleukin-1-beta (IL-1-β)-driven matrix metalloproteinase-1 (MMP-1) and MMP-13 gene expression in SW-1353 chondrosarcoma cells. Other investigators have demonstrated similar effects in chondrocytes treated with rosiglitazone, a ligand for peroxisome proliferator-activated receptor-gamma (PPARγ), for which RXR is an obligate dimerization partner. The goals of this study were to evaluate the inhibition of IL-1--induced expression of MMP-1andMMP-13 by combinatorial treatment with RXR and PPAR  ligands and to investigate the molecular mechanisms of this inhibition.

Laboratory Study Of Responses Of Anuran Amphibians To Roundup¨ Exposures: Experimental Design And Role Of Sediment, Latice Fuentes

All Theses

The contribution of incidental exposures of Roundup¨ herbicide to amphibian declines can be evaluated with carefully designed laboratory tests. Sensitive, sentinel species of larval anurans were exposed to two formulations: the original formulation of Roundup¨ and Roundup WeatherMax¨ in 96-hour acute, aqueous and water-sediment tests. An experimental design was developed that considered and held constant relevant laboratory conditions which produced precise, replicable data. Experimental design factors decreased variability and increased precision by considering and incorporating the following: 1) range-finding tests; 2) reference toxicity tests; 3) the relative sensitivity of the species tested; 4) differences in formulation; 5) the number of …

Ecm Stabilization Strategies For Bioprosthetic Heart Valves For Improved Durability, Devanathan Raghavan

All Dissertations

Abstract
Approximately 85,000 heart valve replacement surgeries are performed every year in United States and about 300,000 surgeries worldwide. It is estimated that half of them are mechanical valve replacements and the other half bioprosthetic valve replacements. The use of bioprosthetic heart valves is slowly increasing. Bioprosthetic heart valves are made from porcine aortic valves or bovine pericardium. Commercially these bioprostheses are currently crosslinked using glutaraldehyde (GLUT) to prevent tissue degradation and reduce tissue antigenicity. GLUT crosslinks these bioprostheses by stabilizing the collagen present in the tissue via a Schiff base reaction of the aldehyde with the hydroxylysine / lysine …
