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 …

A unified library of nonlinear solution schemes: An excursion into nonlinear computational mechanics
A library of nonlinear solution schemes including load, displacement, arc-length, work, generalized displacement, and orthogonal residual control are cast into a unified framework for solving nonlinear finite element systems. Each of these solution schemes differs in the use of a constraint …

Predicting Pilot Misperception of Runway Excursion Risk Through Machine Learning Algorithms of Recorded Flight Data
… 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 stable approach as an aircraft …

Reliability and Validity of the Condition-Modified Star Excursion Balance Test: Influence of Concussion History
… measure is both. The unique nature of the Star Excursion Balance Test (SEBT) may provide both a cost effective and sensitive measure of balance for concussion assessment though the current protocol may not even be sufficient. The Condition-Modified Star Excursion Balance Test (CM-SEBT) uses the …

Experimental study of transient pool boiling heat transfer under exponential power excursion on plate-type heater
Conduction and single-phase convective heat transfer are well understood phenomena: analytical models [1] 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 …

An Examination of Contributing Factors to Star Excursion Balance Test in Individuals with and without Chronic Ankle Instability
… which factors contribute the most to Star Excursion Balance Test (SEBT) performance in the CAI and healthy control groups. Design: A case-control study. Setting: Research laboratory. Participants: Twenty healthy control participants (M=6, F=14, 20.5±1.3 yrs, 70.63± 15.9 kg, 167.52±11.1 cm.) …

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 …

Carbon cycle changes during the end-Marjuman (Cambrian) extinction in the Southern Appalachians
… with the Steptoean Positive Carbon Isotope Excursion or SPICE, a large and rapid excursion in the marine carbon isotope record. This excursion, which is expressed in sedimentary successions globally, is thought to represent a large perturbation to the carbon cycle during this time. …

Head Position Variability During Single and Dual-task Tandem Gait Concussion Testing Protocol
… The time to complete the task and average mean excursion in the ML direction, velocity in the ML direction, were ensemble averaged and compared using a repeated measures ANOVA. RESULTS: A significant difference was found for single-task FP mean excursion ML (CN=1.78±0.54cm, CF=1.49±0.38cm; …

On Verification of Load Models for Frequency Response Using PMU Data
During frequency excursions, not only generators respond to the frequency deviation. Most electric loads are sensitive to large variations in frequency that change their power consumption as a result. Therefore, load modeling is a crucial element in power system simulation, and a better …

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
… affect neuromuscular performance on the Star Excursion Balance Test (SEBT) following fatigue of the hip musculature. In a randomized control trial, set in a laboratory, 20 male and 20 female recreationally active subjects with no history of lower extremity injury were recruited to participate …

Chemostratigraphy of the Uppermost Cambrian Below the Ordovician GSSP
… negative. The δ13C values reveal a negative excursion at and below the Cambrian‒Ordovician boundary, which may correlate with the Top of Cambrian Carbon Isotope Excursion (TOCE) and its significant negative excursion. A nadir of -6.44 ‰ at the base of the Eoconodontus conodont zone marks the …

Acute Effects of Biomechanical Muscle Stimulation to Lower Extremity Using the Swisswing® on SEBT Scores in Persons With and Without Chronic Ankle Instability
… control by evaluating performance on the star excursion balance test (SEBT) among uninjured and chronic ankle instability (CAI) subjects. Forty subjects aged 18 to 26 who participated in physical activity at least two times a week were placed in two groups: CAI or non-CAI group. Subjects …
