An ancient pheromonal signal is found in aquatic courting salamandrids and terrestrial courting plethodontids, two highly divergent salamander families. In the aquatic courting salamandrids Cynops pyrrhogaster and C. ensicauda, the decapeptide sodefrin is cleaved from a larger 189 amino acid Sodefrin Precursor Factor (SPF) protein and released from a gland...
A widely held belief is that the pre-2018 U.S. repatriation tax has led to stockpiles of cash of multinational corporations being trapped overseas, but there is evidence showing that firms are issuing debt to access cash. Standard and Poor has documented this phenomenon as “synthetic cash repatriation.” This study examines...
The primary purpose of this study was to replicate a study of
Abel and Sahinkaya which investigated the emergence of race and sex
preferences of upper middle socioeconomic status Caucasian
children. This study provided a good match with respect to socioeconomic
status, race, and sex; however, the number of subjects...
Reservoir systems in the western US are managed to serve two main competing purposes: to reduce flooding during the winter and spring, and to provide water supply for multiple uses during the summer. Because the storage capacity of a reservoir cannot be used for both flood damage reduction and water...
The lentil strain of pea seedborne mosaic virus, PSbMV-L, was
distinguished from the standard isolates of PSbMV by a natural inoculum
reservoir in lentil seed and by separate resistance genes in Pisum
and Lens. PSbMV-L was intermediate in symptom severity between the
standard and New Zealand isolates of PSbMV.
Seed...
Because arginine vasotocin (AVT) activates male sexual behaviors in the rough-skinned newt (Taricha granulosa), quantitative autoradiography with radiolabelled arginine vasopressin (³H-AVP) was used to localize and characterize putative AVT receptors in the brain of this amphibian. Binding of ³H-AVP to sites within the medial pallium was saturable, specific, reversible, of...
An analysis was conducted to determine the effects of nonlinearity in
the one dimensional Navier-Stokes equation describing a viscous fluid flow.
An attempt was made to numerically determine the effect of temperature
variance on the fluid, either by varying the constant viscosity factor in the
energy dissipative term in the...
Traditionally, livestock operations were small and combined with cropping operations. This allowed farms to be self-sustaining because nutrients were constantly recycled on the farm. Since the Haber-Bosch chemical process was patented, crop farmers turn to industrial fertilizers when soils nutrients are depleted. Animal and plant operations diverged, functionally separated, and...
