• Research toward the synthesis of heliquinomycin ﻿

(2007)
Heliquinomycin, a member of a rubromycin family of natural products, is a complex natural product consisting of a naphthoquinone and an isocoumarin which are linked through a 5,6-spiroketal functionality. The spiroketal ...
• Research toward the total synthesis of lactonamycin and related polyketides ﻿

(2004)
Research toward the total synthesis of the promising antibiotic lactonamycin is reported. Lactonamycin exhibits a wide range of potentially useful biological activities. Most notable among these, is the potent activity ...
• Research towards the synthesis of the furanosteroid class of natural products ﻿

(2003)
The goal of this research was to explore new routes for the construction of viridin- and xestoquinone-related classes of natural products along with similar non-natural products. The four main targets being addressed are ...
• Resettlement Community Center ﻿

(2017-04-21)
American small-town industrial decline and global political economic instability are interconnected. The recent US presidential election showed how Americans are grappling with the issue of immigration. While cities across ...
• Reshaping the metallic surface of a gold nanoshell ﻿

(2004)
Two methods for the controlled reshaping of metal nanoparticles have been investigated: pulsed laser induced reshaping and surfactant-mediated restructuring. The laser induced shape changes of gold nanoshells have been ...
• Residence, Race, and Shared Resources: Does Kin Support Matter for Neighborhood Attainment? ﻿

(2015-08-27)
Vast racial disparities exist in terms of neighborhood quality, and a substantial body of literature on this topic has focused on the role of individuals’ race and socioeconomic status in structuring these outcomes. The ...
• Residential frameworks for the transient: A critical analysis of object event relationships in transient residential sites ﻿

(1995)
This thesis is an effort to respond to our unstable, de-centered quality of living. The single family house is not reflective of our dependency on mobility. As the ultimate transient, the homeless are the inspiration behind ...
• Residual flexibility methods for decoupled analysis of integrated structural systems ﻿

(1998)
Methods of dynamic analysis of large structural systems used in aerospace applications are examined. Full-system solutions are undesirable due to computational cost and logistics issues. Traditional substructuring methods ...
• Residually finite properties of covering spaces ﻿

(1972)
The purpose of this thesis is trying to construct some negative results for Griffith’s theorem 1 in (3) by showing theorem 1.1 and a counter-example in Section 2. I also give some general positive results for this work in ...
• Residues controlling the function and stability of the CD corner in myoglobin and hemoglobin ﻿

(1995)
All globins consist of eight $\alpha$ helices labelled A through H and connected by loop regions, except mammalian $\alpha$ globins which lack a D helix. Myoglobin is used as a simple model for the study of the hemoglobin ...
• Resilience Assessment of Electric Grids and Distributed Wind Generation under Hurricane Hazards ﻿

(2015-04-21)
Modern society is increasingly dependent on high quality electricity for its economy, security, cultural life, public health, safety and governance. As such, ensuring the resilience of electric power systems against ...
• Resistive Switching and Memory effects in Silicon Oxide Based Nanostructures ﻿

(2012)
Silicon oxide (SiO x 1 ∠ x [∠, double =]2) has long been used and considered as a passive and insulating component in the construction of electronic devices. In contrast, here the active role of SiO x in constructing a ...
• Resistive switching in silicon oxide-based systems ﻿

(2010)
Voltage-controlled resistive switching in various gap systems on SiO2 substrates is demonstrated. The nanosized gaps are made by several means using different materials including metals, semiconductors and amorphous carbon. ...
• RESISTOMETRIC STUDY OF IRON-BASED ALLOYS NITRIDED BY CONSTANT ACTIVITY AGING ﻿

(1982)
Constant activity nitriding experiments were performed in Fe-V and Fe-Mo alloys. The nitriding was accomplished aging the alloys in a NH(,3)/H(,2) atmosphere at temperature between 400(DEGREES)C and 600(DEGREES)C, during ...
• Resistor networks and optimal grids for the numerical solution of electrical impedance tomography with partial boundary measurements ﻿

(2010)
The problem of Electrical Impedance Tomography (EIT) with partial boundary measurements is to determine the electric conductivity inside a body from the simultaneous measurements of direct currents and voltages on a subset ...

(1957)
• Resolving the nanoscale mechanisms of calcite growth and dissolution from nonstoichiometric and microbial solutions ﻿

(2008)
The relative rates of calcite (CaCO3) precipitation and dissolution largely determine the preservation and subsequent accumulation of carbonate in the geologic record and are fundamental parameters for predicting the fate ...
• Resonances for carbon bombarded by deuterons ﻿

(1948)
Abstract Not Available.
• RESONANT AND NONRESONANT PION PRODUCTION AT 790 MEV ﻿

(1982)
Fifth-order differential cross sections, (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI) have been measured for the reaction n+p(--->)p+p+(pi)('-) at an incident neutron energy of 790 (+OR-) 5 MeV. The experiment was ...
• Resonant Compton Scattering in Highly-Magnetized Pulsars ﻿

(2014-04-24)
Soft gamma repeaters and anomalous X-ray pulsars are subset of slow-rotating neutron stars, known as magnetars, that have extremely high inferred surface magnetic fields, of the order 100-1000 TeraGauss. Hard, non-thermal ...
