Endangered languages, technology and learning: A Yakama/Yakima Sahaptin case study
Efforts to support Indigenous and endangered language education continue to utilize technology in a variety of ways. As the vitality of many languages around the world continues to be threatened, it is important to reassess ... -
“Endless Opportunities”: A Qualitative Study on Improving Two-Way Texting For Medical Male Circumcision Clients In Zimbabwe
Background: Evidence shows that voluntary medical male circumcision (VMMC) as a one-time prevention method is a cost-effective way to reduce HIV transmission. In Zimbabwe, there is an HIV prevalence of 14.6% among adults, ... -
Endocrine growth regulation in salmon: mechanisms of nutritional control of the growth axis
(2003)Vertebrate growth is regulated by the growth endocrine axis, which consists of pituitary growth hormone (GH), liver insulin-like growth factor-I (IGF-I), and IGF binding proteins (IGFBPs). Studies were conducted to ... -
The endocrinology and evolution of tropical social wasps: from casteless groups to high societies
(2013-04-17)The endocrinology and behavior of three social vespid wasps was studied in northeast Brazil (São Cristóvão, Sergipe) from 2010-2011. There were two main objectives of this work: to test a hypothesis on the origin of ... -
Endogenous and exogenous extracellular microRNA transfer
MicroRNAs are small non-coding RNA molecules that post-transcriptionally regulate gene expression by repressing specific target mRNAs. Although most miRNAs regulate gene expression intracellularly, extracellular miRNAs ... -
Endogenous Biomarkers of CYP3A Activity
(2013-07-25)The activity of the drug-metabolizing enzyme cytochromes P450 3A (CYP3A) varies up to 20-fold between individuals. The interindividual variability may be due to both genetic variations and factors such as age, diet, ... -
The Endogenous Hormonal Milieu Associated with Thrombosis in Postmenopausal Women
Although the use of exogenous hormones, such as hormone therapy (HT) and oral contraceptives (OC), is known to be positively associated with the risk of venous thrombosis (VT), the endogenous hormonal environment associated ... -
Endosomolytic Biomaterial Vaccines for Cancer Therapy
Stimuli-responsive biomaterials are useful for a variety of therapeutic applications because they function in concert with naturally occurring biological processes. This dissertation is focused on applications of a ... -
Endothelial cell interactions with model surfaces: effect of surface chemistry, surface mobility, and the adsorbed protein layer
(1999)The clinical success of the small diameter vascular graft remains limited due to occlusion resulting from thrombus formation. Methods for promoting graft endothelialization have been investigated to improve graft healing. ... -
The Energetic Constraints on the Zonal Mean Atmospheric Circulations in the Tropics, Midlatitudes, and High Latitudes
(2013-07-25)In this doctoral thesis, I have studied the processes that affect the atmospheric energy budget and their coupling relationships with atmospheric circulations. The equator-to-pole radiation gradient at the top of the ... -
Energetics of Catalytic Intermediates on Nickel(111) by Calorimetry: Empirical Trends and Benchmarks for Quantum Theory
Our society depends on the use of catalysts for the manufacture of 90% of chemical industry products, for the mass production of fertilizers that grow our food supply, for the synthesis of the fuels that drive our ... -
Energetics of Elementary Steps in Catalysis and Their Use to Search for New Catalysts
We live in a society based upon the mass production of chemicals. Whether it is the fuel in a car, the fertilizers used to make food, or the plastics present in just about everything, these chemicals are so ubiquitous that ... -
Energetics of Small Molecules and Molecular Fragments on Model Catalyst Surfaces: Calorimetric Adsorption and Adhesion Energies on Pt, Ni and Cu(111)
Heterogenous catalysts are essential for our society. From the production of food and energy to the manufacture of chemicals and the mitigation of pollution, catalysts touch every facet of our lives. In order to maintain ... -
Energetics of Small Molecules and Molecular Fragments on Model Catalyst Surfaces: Adsorption Calorimetry on Pt(111) and Cu(111)
Heterogeneous catalysis is essential for the development and support of modern society, with the vast majority of chemical production processes reliant on catalysts. New catalysts and catalytic reactions constitute promising ... -
Energetics, synthesis, and structural characteristics of ferromagnetic metals for shape memory alloy and catalysis
The ferromagnetic metals iron and nickel have valence d electrons that allow for magnetic responsivity and catalytic activity, enabling their use in a variety of applications. The iron–palladium alloy Fe70Pd30 is a ... -
Energy and Charge Transfer in Open Plasmonic Systems
Coherent and collective charge oscillations in metal nanoparticles (MNPs), known as localized surface plasmons, offer unprecedented control and enhancement of optical processes on the nanoscale. Since their discovery in ... -
Energy and Moisture Transport in the Earth Climate System: Mean State and the Perturbation Response
Four studies are presented which investigate how energy and moisture transport define the mean state of the Earth Climate System and its response to perturbations. In the first study, we use a global climate model to study ... -
Energy and volume flux into the deep ocean: examining diffuse hydrothermal systems
(2004)Hydrothermal circulation plays an important role in the chemistry of the world's oceans, the biology beneath and at the seafloor---as well as within the ocean itself---and also the geology of the uppermost igneous oceanic ... -
Energy Commons: A Hypothetical Replacement for Urban Gas Stations in Seattle
While surviving as a monument to the power of car culture in the 20th century, today the gas station has become increasing obsolete in the face of growing cities and increasing environmental awareness. Alternative energy ... -
Energy Expenditure in Patients Undergoing Targeted Temperature Management at 36°C After Cardiac Arrest, the Effect of Shivering and Ability to Maintain Goal Temperature
Survivors of cardiac arrest undergo targeted temperature management (TTM) in the intensive care unit as a strategy to promote neurologic recovery and prevent further cellular injury from post-cardiac arrest syndrome (PCAS). ...
