No full textGSWA Gibb Rock uranium grid geodetic
No full textMaintenance and Update Frequency: notPlannedStatement: This GSWA Gibb Rock uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the Gibb Rock, WA, 1997 survey. The survey was acquired in 1997 under the project No. 1076 for the geological survey of WA. The data consisted of 4250 line-kilometres of data at 200m line spacing and 40m terrain clearance. The radiometric count rate is contaminated by background radiation contributions from the aircraft, cosmic rays, and the presence of Radon gas escaping from the ground. It is also affected by the ground clearance of the detector, as well as the volume of the detector. This grid was produced after applying radiometric corrections to the uranium window data from the survey. The final grid is checked for quality by GA geophysicists to ensure that the final data released are fit-for-purpose. This GSWA Gibb Rock uranium grid geodetic has a cell size of 0.0005 degrees (approximately 51m) and shows the uranium window countrate of the Gibb Rock, WA, 1997 survey in units of counts per second (or cps). Noise-adjusted singular value decomposition (NASVD) has been applied to the data. NASVD is a spectral component analysis procedure for the removal of noise from gamma-ray spectra. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). This Index is also available online at http://pid.geoscience.gov.au/dataset/79134.

Index of airborne geophysical surveys (Fourteenth Edition).This GSWA Gibb Rock uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the Gibb Rock, WA, 1997 survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of uranium (K), uranium (U) and uranium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface.

Gibb Rock, WA, 1997 (P1076), radiometric line data, AWAGS levelled
No full textMaintenance and Update Frequency: notPlannedStatement: This Gibb Rock, WA, 1997 (P1076), radiometric line data, AWAGS levelled is an airborne-derived radiometric data for the Gibb Rock, WA, 1997. The data was acquired under the project No. 1076 for the geological survey of WA. A total of 4250 line-kilometres of data at a line spacing of 200m were acquired during this survey. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data (Milligan et al., 2009). This survey data is essentially levelled to AWAGS. Noise-adjusted singular value decomposition (NASVD) has been applied to the data. NASVD is a spectral component analysis procedure for the removal of noise from gamma-ray spectra.

Thermodynamic Profiles of Salt Effects on a Host–Guest System: New Insight into the Hofmeister Effect
No full textIsothermal titration calorimetry
was used to probe how salts influence
the thermodynamics of binding of guests to cavitand <b>1</b>. Studies involved six Hofmeister salts covering the range of salting-in
to strongly salting-out. The latter were found to reduce affinity.
The cause of this was competitive binding of the weakly solvated anion
to the hydrophobic pocket of the host. At the other extreme of the
Hofmeister series, salts increased guest affinity. Two factors for
this were evident. At low concentrations the data fitted a previously
reported model that accounts for cation condensation to the outer
carboxylates of the host (Carnagie, R.; Gibb, C. L. D.; Gibb, B. C., <i>Angew. Chem., Int. Ed.</i> <b>2014</b>, <i>53</i> (43), 11498–11500). At higher concentrations, an as of yet
unidentified contribution was observed that was noted to be guest
dependent. Midcontinuum salts such as NaClO<sub>3</sub> were found
to enhance affinity at low concentrations, but weaken it at high concentrations;
a nonmonotonic trend attributed to the aforementioned competing phenomena.
In combination with previous work, the data presented here reveal
that the Hofmeister effect evident in this system can be mostly attributed
to solute–salt interactions
Physical dance performance: An investigation into the development of a performance technique based on the integration of certain Korean dance technique and contemporary Western styles of dance and physical theatre
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 04/10/2001.This development of a performer practice that integrates elements of traditional Korean dance technique and Western forms of physical theatre and contemporary dance is based on an approach to internal understanding and external execution. Central to the work is the concept of body energy, or Ki. This ancient Eastern term is translated into a contemporary practice that enables a performer to engage mental and physical training. Breath and the use of breath in performing are the principal means of achieving this level of engagement

Electrostatic Potential Field Effects on Amine Macrocyclizations within Yoctoliter Spaces: Supramolecular Electron Withdrawing/Donating Groups.
No full textThe central role of Coulombic interactions in enzyme catalysis has inspired multiple approaches to sculpting electrostatic potential fields (EPFs) for controlling chemical reactivity, including ion gradients in water microdroplets, the tips of STMs, and precisely engineered crystals. These are powerful tools because EPFs can affect all reactions, even those whose mechanisms do not involve formal charges. For some time now, supramolecular chemists have become increasingly proficient in using encapsulation to control stoichiometric and catalytic reactions. However, the field has not taken advantage of the broad range of nanocontainers available to systematically explore how EPFs can affect reactions within their inner-spaces. With that idea in mind, previously, we reported on how positively and negatively charged supramolecular capsules can modulate the acidity and reactivity of thiol guests bound within their inner, yoctoliter spaces (Cai, X.; Kataria, R.; Gibb, B. C. J. Am. Chem. Soc. 2020, 142, 8291-8298; Wang, K.; Cai, X.; Yao, W.; Tang, D.; Kataria, R.; Ashbaugh, H. S.; Byers, L. D.; Gibb, B. C. J. Am. Chem. Soc. 2019, 141, 6740-6747). Building on this, we report here on the cyclization of 14-bromotetradecan-1-amine inside these yoctoliter containers. We examine the rate and activation thermodynamics of cyclization (Eyring analysis), both in the absence and presence of exogenous salts whose complementary ion can bind to the outside of the capsule and hence attenuate its EPF. We find the cyclization rates and activation thermodynamics in the two capsules to be similar, but that for either capsule attenuation of the EPF slows the reaction down considerably. We conclude the capsules behave in a manner akin to covalently attached electron donating/withdrawing groups in a substrate, with each capsule enforcing their own deviations from the idealized SN2 mechanism by moving electron density and charge in the activated complex and TS, and that the idealized SN2 mechanism inside the theoretical neutral host is relatively difficult because of the lack of solvation of the TS
