Magmatic-hydrothermal ore deposits are giant geochemical anomalies in the earth’s crust most often generated by normal magmatic terrestrial processes. They are often associated with oxidized and hydrous intermediate to highly evolved magmas that have concentrated metals and have the necessary components to efficiently extract and transport them as ascending magmatic-hydrothermal...
Metagenomics has revealed that the marine microbial biosphere is immensely more diverse than originally considered, and is an almost untapped reservoir for the potential discovery of microbial natural products. Despite numerous advances in culturing, biosynthetic engineering and genomic-based screening efforts to uncover much of this diversity in relatively accessible environments,...
Analytical chemistry is an essential qualitative and quantitative tool to describe foods and biomaterials and their changes during production, processing and distribution. In this work, rapid analytical procedures for the extraction and quantification of components in fluid milk and diatom fermentation broth were developed. Analytical methods to measure the concentration...
A blood supply chain (BSC) deals with the collection, processing, storing, and distribution of blood collected from donors and delivered to patients at demand points (DPs) through a network of several temporary mobile blood units (MBUs) and permanent local blood centers (LBCs). In general, the strategic and tactical design of...
Microbial natural products represent a massive repository of unique chemical scaffolds with corresponding diverse biological functions. However, in the past decade the development of natural products into new therapeutics has dwindled, in part due to the challenges posed by high rediscovery rates and low throughput associated with classical bioassay-guided fractionation...
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death in the United States. Patients with cirrhosis are more likely to develop HCC. More than 80% of HCC patients are found have preexisting cirrhosis. The prevalence of cirrhosis increased from 0.26% to 0.3.% between 1999 to 2010 and...
Unmet healthcare needs and/or delays in needed care are widespread among patients with serious mental illness (SMI). Mental healthcare delivery has changed dramatically over the last two decades. Although access to mental health specialists remains challenging, mental healthcare is now increasingly provided in primary care settings. However, it is unclear...
Andesitic and rhyolitic magmatism was active during the mid-
Tertiary (Early Miocene) of the Ash Peak area, southeastern Arizona.
Andesitic magmas of similar composition both preceded and followed the
low- and high-silica rhyolitic magmas. The changes from andesitic to
rhyolitic and back to andesitic volcanism is postulated to be the...
We are at risk of losing the sagebrush steppe in the floristic Great Basin to the invasion of Bromus tectorum L., cheatgrass. The floristic Great Basin includes the Central Basin and Range, the Northern Basin and Range, and the Snake River Plain. The Great Basin receives most of its precipitation...
The aim of this dissertation is to construct a virtual element method (VEM) for models in magneto-hydrodynamics (MHD), an area that studies the behavior and properties of electrically conducting fluids such as a plasma. MHD models are a coupling of the Maxwell’s equations for electromagnetics and models for fluid flow....
