Auckland Volcanic Field Olivine Research Poster for AGU Fall 2013_Smidelainesmid
This poster was presented at the American Geophysical Union's Fall 2013 scientific conference. It describes research results from chemical analyses of olivine minerals found in the deposits of the Auckland Volcanic Field, New Zealand. This research is a part of the publicly-funded DEtermining VOlcanic Risk in Auckland project.
Dr. Frans W.A. Brom heeft op 12 april 2011 de leerstoel Ethiek van Technology Assessment aan de Universiteit Utrecht aanvaard. Hij deed dit met het uitspreken van de oratie ‘Thuis in de Technologie’.
Controls on the fo and ni contents of olivine in sulfide bearing mafic ultram...xirey
This document summarizes controls on the nickel and magnesium contents of olivine in mafic and ultramafic intrusions. It discusses how fractional crystallization, reaction with sulfide liquids, and trapped liquid modification can impact olivine composition. It then uses examples from the Voisey's Bay intrusion in Canada, which hosts a major nickel-copper deposit, to demonstrate modeling approaches to understand these processes and better interpret olivine compositions in such intrusions.

The document reports on the discovery of olivine on the surface of the asteroid Vesta in unexpected locations, based on data from the Dawn spacecraft's VIR instrument. Specifically:
- Olivine was found in the northern hemisphere of Vesta, rather than the southern basins where mantle rocks were expected based on previous models.
- The olivine occurs in large patches hundreds of meters across mixed with howardite regolith, unlike in meteorites where it is a minor component of diogenites.
- The amount and distribution of olivine-rich material suggests a complex evolutionary history for Vesta and is not consistent with previous ideas of olivine occurrence being associated with diogenites

This document discusses a researcher's work developing brain-computer interfaces (BCI). It describes measuring EEG brain activity during tasks to extract features and predict the tasks using linear models. The researcher received a grant to validate plans for a BCI company but found no commercial viability. The document also discusses issues with early BCI hardware performance and the researcher's new work on a stress-sensing wearable and matching startups to corporate investors.
