A series of combined measurements was made at the Naval Air Station North Island (NASNI) Installation Restoration Site 5, Unit 2 during July and August 2013. Combined measurements included CO₂ respiration rate, CO₂ radiocarbon content to estimate chlorinated hydrocarbon (CH) mineralization and a zone of influence (ZOI) model. CO₂ was...
Communities throughout the world have grappled with the positive and negative impacts of tourism for years. Oregon State University’s (OSU) Sustainable Tourism Lab was created in 2021 to support such global destinations and help them pursue a sustainable path – inclusive of economic, community, and environmental perspectives. Our first step...
In his July 31, 1996 remarks on welfare reform, President Clinton signaled his intent to sign into law the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA), bipartisan legislation aimed at reforming federal welfare policy. During the press conference, Clinton framed welfare as necessary but ultimately temporary relief, stating its...
Transacting siRNA (tasiRNA) biogenesis in Arabidopsis is initiated
by microRNA (miRNA) –guided cleavage of primary transcripts. In
the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)–
miR390 complexes interact with primary transcripts at two sites,
resulting in recruitment of RNA-DEPENDENT RNA POLYMERASE6
for dsRNA biosynthesis. An extensive screen for Arabidopsis mutants...
The research reported here was a preliminary study to assess the nature and extent of herbicides leaving the target area in runoff water when these materials are used in container nurseries, and with less emphasis from nurseries growing field stock.
Specific objectives of this study were to:
1) Survey the...
Where a legacy of aggressive wildland fire suppression has left forests in need of fuel reduction, allowing wildland fire to burn may provide fuel treatment benefits, thereby reducing suppression costs from subsequent fires. The least-cost-plus-net-value-change model of wildland fire economics includes benefits of wildfire in a framework for evaluating suppression...
In RNA-directed silencing pathways, ternary complexes result from small RNA-guided ARGONAUTE (AGO) associating with target transcripts. Target transcripts are often silenced through direct cleavage (slicing), destabilization through slicer-independent turnover mechanisms, and translational repression. Here, wild-type and active-site defective forms of several Arabidopsis thaliana AGO proteins involved in posttranscriptional silencing were...
The photoelectron spectra of a series of ketone
compounds have been investigated in the gas phase. Core
ionization energies were measured to probe the effects of
molecular size and connectivity number on core ionization
energies.
It was found that core ionization energies roughly
decrease with increasing connectivity number as expected....
