The f-plane linear shallow-water equations support coastal Kelvin waves. These waves propagate along the coast and have zero velocity normal to the coast. It is shown that the balance equations also support coastal Kelvin waves, but these waves differ depending upon the boundary conditions imposed. Three different boundary conditions and...
Cosmogenic-burial and U-series dating, identification of fluvial terraces and lacustrine
deposits, and river-profile reconstructions show that capture of the Gunnison River by
the Colorado River and abandonment of Unaweep Canyon occurred between 1.4-0.8
Ma. This event led to a rapid pulse of incision unlike any documented in the Rocky
Mountains....
Endogenous small RNAs (endo-siRNAs) interact with Argonaute (AGO) proteins to mediate
sequence-specific regulation of diverse biological processes. Here, we combine deep-sequencing and
genetic approaches to explore the biogenesis and function of endo-siRNAs in C. elegans. We describe
conditional alleles of the dicer-related helicase, drh-3, that abrogate both RNA interference and...
Background:
Masons have the highest rate of overexertion injuries among all construction trades and rank second for occupational back injuries in the United States. Identified ergonomic solutions are the primary method of reducing exposure to risk factors associated with musculoskeletal disorders. However, many construction workers lack knowledge about these solutions,...
Spanish Abstract:
El descubrimiento de un depósito de artefactos conteniendo puntas de proyectil en la
Tradición de Tallo Occidental (Western Stemmed Tradition) en una fosa claramente
definida, en el sitio de Cooper’s Ferry, ofrece una perspectiva única sobre la tecnología
lítica temprana y organización logística en el Occidente de América...
Objective. The purpose of this study was to improve understanding of
who experiences insurance-based discrimination during prenatal care, labor, and delivery
and how their health care may differ from that of other women. Methods. We pooled data
from the 1998-99, 2000, and 2001 Oregon Pregnancy Risk Assessment Monitoring System
and...
