An excursion into the synthesis of novel flavanones
The aim of this project was to develop new methodology for synthesizing flavanones asymmetrically in a manner that could be extended to the synthesis of novel indoloflavanone analogues. The designated approach was via an asymmetric aldol reaction catalysed by a chiral organocatalyst followed by an …

An excursion with the Boltzmann equation at low speeds : variance-reduced DSMC
The goal of the present thesis is to develop a practical method for simulating low-signal kinetic (small-scale) gaseous flows. These flows have recently received renewed attention in connection with the design and optimization of MEMS/NEMS devices operating in gaseous environments; they are …

Reliability and Validity of the Condition-Modified Star Excursion Balance Test: Influence of Concussion History
… linked in a cyclical relationship that outlines the necessity of balance assessment tools in the diagnosis, prevention and rehabilitation of injuries. Despite this necessity, many challenges present in relation to assessment protocols and utility. For concussion assessment, the Balance Error …

A unified library of nonlinear solution schemes: An excursion into nonlinear computational mechanics
… nonlinear finite element systems. Each of these solution schemes differs in the use of a constraint equation for the incremental-iterative procedure. The governing finite element equations and constraint equation for each solution scheme are combined into a single matrix equation, which …

Predicting Pilot Misperception of Runway Excursion Risk Through Machine Learning Algorithms of Recorded Flight Data
<p>The research used predictive models to determine pilot misperception of runway excursion risk associated with unstable approaches. The Federal Aviation Administration defined runway excursion as a veer-off or overrun of the runway surface. The Federal Aviation Administration also defined a …

Experimental study of transient pool boiling heat transfer under exponential power excursion on plate-type heater
… and empirical correlations [2] allow capturing the thermal behavior of plate-type fuels or heaters in contact with a single-phase coolant. On the other hand, transient boiling heat transfer is a scarcely studied and much less understood phenomenon. Although, earlier studies have shown that …

Sabbatian influences on the Chassidic and Mitnagdic movements : an excursion into messianic Kabbalah and its disseminators in the aftermath of Shabbatai Tzvi
This study hypothesises that as a result of a thorough analysis of the context and content of rabbinic texts, including the known associations of their authors − spanning the periods of Shabbatai Tzvi, the Baal Shem Tov and the Vilna Gaon − the conclusion can be reasonably drawn that the Chassidic …

An Examination of Contributing Factors to Star Excursion Balance Test in Individuals with and without Chronic Ankle Instability
Objective: The purposes of this study were to determine if differences exist in sagittal plane strength at the ankle and knee, static and dynamic postural control, ankle dorsiflexion range of motion (DFROM), and ankle laxity between individuals with and without chronic ankle instability (CAI) as …

Carbon cycle changes during the end-Marjuman (Cambrian) extinction in the Southern Appalachians
The late Cambrian-early Ordovician transition contains several trilobite extinctions. The first of these extinctions (the end-Marjuman) is thought to coincide with the Steptoean Positive Carbon Isotope Excursion or SPICE, a large and rapid excursion in the marine carbon isotope record. This …

Chemostratigraphy of the Uppermost Cambrian Below the Ordovician GSSP
… profiles for sedimentary sequences supplementing the need for distinguishing fossils from different depositional environments and those lacking fossil materials. The Global Boundary Stratotype Section and Point (GSSP) of the Cambrian‒Ordovician boundary is located at Green Point in the Green Point …

THE EFFECTS OF INITIAL HIP ABDUCTION AND EXTERNAL ROTATION STRENGTH AND NEUROMUSCULAR FATIGUE OF THE GLUTEUS MEDIUS ON THE STAR EXCURSION BALANCE TEST IN MALE AND FEMALE HEALTHY SUBJECTS
The gluteus medius muscle is an essential hip stabilizer during unilateral stance. A weakened or fatigued gluteus medius may be associated with decreases in postural control during dynamic balance. The objective of this study was to determine if initial hip muscular strength and gender affect …

Carbonate Carbon Isotope Chemostratigraphy from the Ruby Ranch Member of the Cedar Mountain Formation in the Western San Rafael Swell
The Ruby Ranch Member of the Cedar Mountain Formation in East-Central Utah represents terrestrial deposits in the early Cretaceous Period. This member has been studied at multiple field locations and has been determined to span the Aptian-Albian Boundary based on chemostratigraphic and detrital …

A magmatic trigger for the Paleocene-Eocene Thermal Maximum?

This Paleocene-Eocene Thermal Maximum (PETM) is often cited as an analogue of anthropogenic climate change. Many trigger mechanisms for the carbon release at the PETM have been …

Terrestrial Impacts of the Central Atlantic Magmatic Province on western Pangea
<p>Earth's climate is predominantly controlled by the fluctuation of greenhouse gases, specifically CO2 and CH4, over geologic time. The late Triassic is a period of abrupt climate change that has been associated with a disruption to the global carbon cycle due the emplacement of the Central …
