A suite of eight rocks analyzed by the Curiosity Rover while it was stopped at the Rocknest sand
ripple shows the greatest chemical divergence of any potentially sedimentary rocks analyzed in the early
part of the mission. Relative to average Martian soil and to the stratigraphically lower units encountered as...
The Curiosity rover has analyzed various detrital sedimentary rocks at Gale Crater, among which fluvial and lacustrine rocks are predominant. Conglomerates correspond both to the coarsest sediments analyzed and the least modified by chemical alteration, enabling us to link their chemistry to that of source rocks on the Gale Crater...
This study addresses perceptions, expectations, and values of women who espoused interest in joining National Panhellenic Conference sorority organizations, and the congruence of their beliefs with their first term membership experiences.

Abstract: The ChemCam instrument, which provides insight into martian soil chemistry at the submillimeter scale, identified two principal soil types along the Curiosity rover traverse: a fine-grained mafic type and a locally derived, coarse-grained felsic type. The mafic soil component is representative of widespread martian soils and is similar in...
The ChemCam campaign at the fluvial sedimentary outcrop ‘‘Shaler’’ resulted in observations of 28
non-soil targets, 26 of which included active laser induced breakdown spectroscopy (LIBS), and all of
which included Remote Micro-Imager (RMI) images. The Shaler outcrop can be divided into seven facies
based on grain size, texture, color,...
Naturally occurring assemblies, such as DNA and proteins, utilize intermolecular forces (i.e H-bonding and van der Waals) to assemble. Utilizing these electrostatic interactions has only just started in the past five decades to be a tool used in synthetic chemistry in what is known as supramolecular chemistry. Supramolecular chemistry has...
Export economy has been interrupted in shrimp/prawn, the second largest earning source of Bangladesh due to detection of Nitrofuran in export ed prawns to the EU countries. Around 100 consignments of frozen prawn (Macrobrachium rosenbergii) were rejected at the EU borders between 2005 and 2009. Bangladesh exported shrimp and fish...
The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...

This study was conducted to assess the economic consequences gained from disease-affected extensive shrimp farming by three major farm ownerships: individual, group and outside respectively. Key data for cost and returns were collected using a questionnaire survey between June and August 2002 from southwest Bangladesh. Profitability of operations was affected...
Green-tree retention is being implemented on state and
federal lands in Oregon. Silvicultural prescriptions with
tree and snag retention are thought to mimic natural
disturbance patterns in the Pacific Northwest more closely
than traditional silvicultural practices, which reduce
structural complexity. The effects of green-tree retention
on native bird species in...
The linear stability of a nearly time-periodic, nonlinear, coastal upwelling–downwelling circulation, over alongshore-uniform topography, driven by a time-periodic wind stress is investigated using numerical methods. The near-periodic alongshore-uniform basic flow is obtained by forcing a primitive equation numerical model of coastal ocean circulation with periodic wind stress. Disturbance growth on...

The role of back channel surface chemistry on amorphous zinc tin oxide (ZTO) bottom gate thin film transistors (TFTs) has been characterized by positive bias-stress measurements and x-ray photoelectron spectroscopy. Positive bias-stress turn-on voltage shifts for ZTO-TFTs were significantly reduced by passivation of back channel surfaces with self-assembled monolayers of...
Oxygen is often the rate-limiting factor in aerobic in situ bioremediation. This paper investigates the degree to which air or oxygen gas can be emplaced into the pore space of saturated porous media and provide a significant mass of oxygen. Column experiments were performed to test three emplacement methods: direct...
Anomalous uplift is observed at the Lop Nor, China nuclear test site using ERS satellite SAR data. Using an InSAR time‐series analysis method, we show that an increase in absolute uplift with time is observed between 1997 and 1999. The signal is collocated with past underground nuclear tests. Due to...
A general model of interactive problem solving is described. The model views interactive problem solving to be the product of cooperating subsystems. The operative subsystem selectively attends to and manipulates problem relevant information in search of a solution. The descriptive subsystem is capable of interpreting this behavior and of discussing...
A novel thermal management approach is explored, which uses supercritical carbon dioxide (sCO2) as a working fluid to manage extreme heat fluxes in electronics cooling applications. In the pseudocritical region, sCO2 has extremely high volumetric thermal capacity, which can enable operation with low pumping requirements, and without the potential for...
The role of gene expression in adaptation to differing thermal environments has been assayed extensively. Yet, in most natural systems, analyses of gene expression reveal only one level of the complexity of regulatory machineries. MicroRNAs (miRNAs) are small noncoding RNAs which are key components of many gene regulatory networks, and...
This study investigates wind-driven circulation in the vicinity of the Heceta Bank complex along the Oregon shelf. Numerical experiments forced with steady winds (0.1 Pa) are conducted; upwelling and downwelling cases are compared. The asymmetric bank bathymetry is the only configurational difference from the symmetric bank runs analyzed in Part...
This study examines how coastal banks influence wind-driven circulation along stratified continental shelves. Numerical experiments are conducted for idealized symmetric banks; the standard bank (200 km long and 50 km wide) has dimensions similar to the Heceta Bank complex along the Oregon shelf. Model runs are forced with 10 days...
Observations of oppositely directed, monthly mean alongshore currents and wind stress over the continental margin off the Pacific coast of North America motivate the theoretical examination of mean flow generation by topographic lee-wave drag. We formulate a barotropic model for wind-forced shelf-slope flow over variable topography. Our central objective is...
Internal‐tide generation is usually predicted from local topography, surface tides, and stratification. However, internal tides are often observed to be unrelated to local spring‐neap forcing, appearing intermittently in 3–5 day bursts. Here we suggest a source of this intermittency by illustrating how remotely‐generated shoaling internal tides induce first‐order changes in...

The effects of alongshore variations in bottom topography on wind-stress-forced barotropic motion over a continental shelf and slope are studied. An idealized channel model with a weakly sloping bottom and with small-amplitude alongshore variations in topography is utilized. Perturbation methods and numerical inversion of Fourier transforms are employed. The effect...
A primitive equation model is used to study the finite-amplitude evolution of instabilities associated with the coastal upwelling front.
