RNA interference pathways can involve amplification of secondary siRNAs by RNA-dependent RNA polymerases. In plants, RDR6-dependent secondary siRNAs, including transacting siRNAs (tasiRNAs), arise from transcripts targeted by some microRNAs (miRNAs). In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)-miR390 complexes interact with primary transcripts at two sites, resulting in recruitment...
The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...
Observed declines in native pollinator species worldwide has generated concern and focused research into the disturbances, past and present, which may have contributed to these losses. In grasslands, for example, habitat degradation and fragmentation from historical and current crop production and livestock grazing has left only a few remnants of...
This study considered regional forest policies for sequestering carbon in existing
forests in western Oregon. A model of log markets in western Oregon was employed to
examine the impacts of forest policy changes on future carbon stock, harvests, and
management activities. A carbon tax program, as a mitigation option for...
The advent of high-throughput sequencing (HTS) methods has enabled direct approaches to quantitatively profile small RNA
populations. However, these methods have been limited by several factors, including representational artifacts and lack of
established statistical methods of analysis. Furthermore, massive HTS data sets present new problems related to data processing
and...
Current lathe technology, smaller diameter logs, smaller core diameters, and
the sale of higher grade veneer for use in engineered wood products are all factors
contributing to plywood manufacturers using rougher veneer with different lathe
check characteristics. When rough veneer is encountered, plywood manufacturers
typically increase the adhesive spread rate...
Thirty-six gilts were used in an experiment of 2³ factorial
design. The experiment consisted of two breeds (Yorkshire-
Berkshire and Yorkshire), two feeding regimens (pre-breeding and
post-breeding) and two levels of dichlorvos (2, 2-dichlorovinyl
dimethyl phosphate, 0 and 800 mg. per gilt per day). Pre-breeding
treatment consisted of feeding dichlorvos...
Methods to improve the efficacy of swine barley rations were
evaluated. A literature review pertaining to the subject, three feeding
trials involving 104 swine, and a laboratory investigation were
used in the study.
The effects of pelleting with a new modified pellet die that
produces a dense pellet; supplementation with...
This paper seeks to assess the merits of “Vote With Your Dollar” (VWYD) strategies for consumer and investor activism as a model for changing corporate behavior. A novel framework was constructed to group VWYD strategies and campaigns under shared attributes. To assess one such group, the boycott, the research gathered...

Eukaryotic small RNA (~20-30 nucleotides) are diverse regulatory molecules that repress gene expression at the transcriptional and post-transcriptional levels, defend hosts against invading viruses and defend genomes against selfish DNA elements. Small RNA populations are studied by high-throughput sequencing of the total small RNA fraction isolated from cells, however, the...
A Geographic Information System (GIS) can be a powerful tool for solving land use planning
problems. The synthesis, analysis, and depiction of spatial data make it a valuable tool for land use
planners. A primary issue with GIS is the cost and time required to develop a functional system.
One...
The Pentatricopeptide Repeat (PPR) gene family produces RNA-binding proteins that target organellar transcripts. The PPR family is expanded in land plants, with nearly 450 genes identified in Arabidopsis thaliana. In plants with a Cytoplasmic Male Sterility (CMS) phenotype, members of the PPR family can act as a RESTORER OF FERTILITY...
Accuracy requirements for positioning a vessel in the near shore
area have increased in recent years. To meet these requirements
several electronic positioning systems have been developed. One
such system is the Cubic Autotape Model DM-40. The Autotape is a
circular positioning system which utilizes the phase comparison
between transmitted...
Monoclonal antibodies (MCA) produced against infectious
laryngotracheitis virus (ILTV) of chickens reacted in
western blotting experiments with several different ILTV
protein bands in the absence of tunicamycin which inhibits
carbohydrate synthesis. Most of the MCA lost their
reactivity in western blotting experiments when extracts of
tunicamycin-treated ILTV CELC were used,...
The stability of 1 3-bis(2-chloroethyl)-1-nitrosourea
(NSC 409962)(BCNU) was investigated in several buffered
aqueous media, in mixed solvent and in nonaqueous solvent
systems, and in the presence of several electrolytes and
nonelectrolytes. The degradation rate constant of BCNU in
these systems was calculated from the parameters of the
linear regression of...
The principal objective of this study was to identify
and investigate the underlying basis for variations in the
volumes of exports of U.S. winter pears during the 1947 to
1974 period. A number of factors thought to be of importance
in the determination of the volume of exports of a...
The host fish for this study were collected from January
through June of 1965. Tidepools were selected at Bar View, Cape
Arago, Neptune State Park, Seal Rock, and Yaquina Head. Of the
187 fish examined, 132 were infected. The following host fishes
yielded the following parasites. New Host records are...
