The Mixteco primarily reside in the Mexican State of Oaxaca in Southwestern Mexico. They have been arriving in larger numbers then ever before to this part of the North American continent in the last twenty years.Their experience is composed of different dynamics compared to those of their mainstream Mexican counterpart....
A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...
Pyrenophora tritici-repentis, causal agent of tan spot of wheat, produces multiple
host-selective toxins (HSTs), including Ptr ToxA, encoded for by ToxA, Ptr ToxB,
encoded for by ToxB, and Ptr ToxC. Variable distribution of these three HSTs among
different isolates of P. tritici-repentis, both singularly and in all possible combinations,
defines...
The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...
Four key aspects of the relationship between predatory hoverflies and the aphid pest Brevicoryne brassicae L. on broccoli were investigated in the Willamette Valley, Oregon USA: 1) the relationship between aphid density and hoverfly oviposition, 2) the larval voracity of key hoverfly species, 3) the preferences of hoverflies and broccoli...
This study explores the intrapersonal and interpersonal ecological factors that influence adolescent females' perceptions of sex and the extent to which their perceptions of sex impact onset of sexual intercourse as they mature. Particular attention is given to how depression influences individual, personal and social factors in an adolescent female's...
Complex oscillations including chaotic motions have been identified in off-shore and submerged mooring systems characterized by nonlinear fluid-structure interactions and restoring forces. In this paper, a means of controlling these nonlinear oscillations is addressed. When applied, the controller is able to drive the system to periodic oscillations of arbitrary periodicity....
The DNA mismatch repair (MMR) pathway maintains genomic stability and
reduces cancer risk (colorectal and other internal cancers) by correcting polymerase
errors and activating cell cycle checkpoints and apoptosis in response to DNA damage.
Few studies have examined the influence of commonly encountered environmental
mutagens/carcinogens on the etiology of MMR-deficient...
In today's world, desktop computers have become such an integral part of
our lives that it is practically impossible to imagine anything being done without the
aid of computers. As the world becomes more and more fast paced and users feel a
need to have computers on the go, desktop...
A unique channel surface enhancement technique via diffusion-bonding a layer of conductive fine wire mesh onto the heating wall was developed and used to experimentally study flow boiling enhancement in parallel microchannels. Each channel was 1000 μm wide and 510 μm high. A dielectric working fluid, HFE 7000, was used...
