A land resource survey of the Fall Point coastline, Broome, W.A.
The purpose of this study was to find a suitable location for a bird observatory and provide adequate coastal land resource data for the area. The main selection criteria and conditions were: the location was closely adjacent to major wader roosting and feeding sites; all-seasons access was required; the location provided a site of around 2 1/2 hectares to provide space for one or more buildings, camp ground and associated facilities ; anticipated access tracks, site developments and levels of use
A resource survey of the coastal lands from Vlaming Head to Tantabiddi Well, West Cape Range region
The report comprise four parts; a brief review of the area\u27s climate, discussion of the geomorphology of the major landform units, an assessment of the potential erosion hazards of the surveyed landforms, and recommendations for development
The State of Fraternity/Sorority Research
Over 50 years ago, Baciq and Sgan (1962) wrote, âOnly an increase in the factual data about fraternities will raise the level from the emotional and anecdotal to the rational and logicalâ (p. 95). In their introduction to The Impact of College on Students, Feldman and Newcomb (1969) noted that the periodic assessment of scientific endeavor is essen-tial for any profession. Practitioners often reflect on and discuss the nature of research in their chosen field, but generally only during conferences or in other informal ways. Feldman and Newcomb believed, however, that the reflection on research in a profession such as fraternity and sorority life should be more systemic. Despite these warnings, Fin-egan and Hines (1967) reported in American Fraternities: An Agenda of Needed Research, âNowhere, so far as we know has anyone undertaken a âresearch programâ with college fraternity life as its focusâ (p. 3)...https://scholarworks.wm.edu/educationbookchapters/1049/thumbnail.jp
Pilbara coastal flora
The Pilbara coastal region is an area which will have increased human pressure both for work and recreation. In recent years, rapid expansion of townsites along the coast has meant that areas which were once stable have come under threat. Conservation measures will be needed to protect the coastline, and to ensure that the beauty of the coastal landscape: an be enjoyed by future generations

Minimal Model for Sand Dunes
We propose a minimal model for aeolian sand dunes. It combines an analytical
description of the turbulent wind velocity field above the dune with a
continuum saltation model that allows for saturation transients in the sand
flux. The model provides a qualitative understanding of important features of
real dunes, such as their longitudinal shape and aspect ratio, the formation of
a slip face, the breaking of scale invariance, and the existence of a minimum
dune size.Comment: 4 pages, 4 figures, replaced with publishd versio
Templated Quasicrystalline Molecular Ordering
Quasicrystals are materials with long-range ordering but no periodicity. We report scanning tunneling microscopy (STM) observations of quasicrystalline molecular layers on 5-fold quasicrystal surfaces. The molecules adopt positions and orientations on the surface consistent with the quasicrystalline ordering of the substrate. Carbon-60 adsorbs atop sufficiently separated Fe atoms on icosahedral AlâCuâFe to form a unique quasicrystalline lattice, whereas further C60 molecules decorate remaining surface Fe atoms in a quasi-degenerate fashion. Pentacene (Pn) adsorbs at 10-fold symmetric points around surface-bisected rhombic triacontahedral clusters in icosahedral AgâInâYb. These systems constitute the first demonstrations of quasicrystalline molecular ordering on a templat
Barchan dune corridors: field characterization and investigation of control parameters
The structure of the barchan field located between Tarfaya and Laayoune
(Atlantic Sahara, Morocco) is quantitatively investigated and compared to that
in La Pampa de la Joya (Arequipa, Peru). On the basis of field measurements, we
show how the volume, the velocity and the output sand flux of a dune can be
computed from the value of its body and horn widths. The dune size distribution
is obtained from the analysis of aerial photographs. It shows that these fields
are in a statistically homogeneous state along the wind direction and present a
`corridor' structure in the transverse direction, in which the dunes have a
rather well selected size. Investigating the possible external parameters
controlling these corridors, we demonstrate that none among topography,
granulometry, wind and sand flux is relevant. We finally discuss the dynamical
processes at work in these fields (collisions and wind fluctuations), and
investigate the way they could regulate the size of the dunes. Furthermore we
show that the overall sand flux transported by a dune field is smaller than the
maximum transport that could be reached in the absence of dunes, i.e. in
saltation over the solid ground.Comment: revised version for JGR-ES, 36 pages, 21 figure
Atomic-layer deposited thulium oxide as a passivation layer on germanium
A comprehensive study of atomic-layer deposited thulium oxide (Tm2O3) on germanium has been conducted using x-ray photoelectron spectroscopy (XPS), vacuum ultra-violet variable angle spectroscopic ellipsometry, high-resolution transmission electron microscopy (HRTEM), and electron energy-loss spectroscopy. The valence band offset is found to be 3.05â±â0.2âeV for Tm2O3/p-Ge from the Tm 4d centroid and Ge 3p3/2 charge-corrected XPS core-level spectra taken at different sputtering times of a single bulk thulium oxide sample. A negligible downward band bending of âŒ0.12âeV is observed during progressive differential charging of Tm 4d peaks. The optical band gap is estimated from the absorption edge and found to be 5.77âeV with an apparent Urbach tail signifying band gap tailing at âŒ5.3âeV. The latter has been correlated to HRTEM and electron diffraction results corroborating the polycrystalline nature of the Tm2O3 films. The Tm2O3/Ge interface is found to be rather atomically abrupt with sub-nanometer thickness. In addition, the band line-up of reference GeO2/n-Ge stacks obtained by thermal oxidation has been discussed and derived. The observed low reactivity of thulium oxide on germanium as well as the high effective barriers for holes (âŒ3âeV) and electrons (âŒ2âeV) identify Tm2O3 as a strong contender for interfacial layer engineering in future generations of scaled high-Îș gate stacks on Ge
