California brome and blue wildrye are important native grass species in the Pacific Northwest. However, both species have been reported to have low emergence under less than favorable field conditions. Seed coating is used to improve emergence and stand establishment of various crops. Three studies were carried out to determine...
Log and core data document gas saturations as high as
90% in a coarse-grained turbidite sequence beneath the gas
hydrate stability zone (GHSZ) at south Hydrate Ridge, in the
Cascadia accretionary complex. The geometry of this gas-saturated
bed is defined by a strong, negative-polarity
reflection in 3D seismic data. Because...

A common problem in postal surveys of human populations
arises when some of the sampled people fail to respond to the questionnaire.
The problem is that the answers provided by the respondents
may not be typical of the answers the nonrespondents would
provide if these had been solicited more successfully....
This paper investigates interactions between recreational and commercial fisheries. It introduces the idea of a protected area for recreational fisheries, as a way to reduce conflicts between the two sectors and to preserve the natural resource. It is demonstrated that without a protected area for recreational fisheries, open access may...
Many species have multi-stage life cycles in which the youngest stages (e.g., larvae) are small, dispersive, and abundant, whereas later stages are sessile or sedentary. Quantifying survival throughout such early stages is critical for understanding dispersal, population dynamics, and life history evolution. However, dispersive stages can be very difficult to...
Cogeneration is the simultaneous generation and use of
both electricity (or mechanical power) and thermal energy
from a single fuel source. It is a technology that has been
used for years by industries, commercial institutions, and
municipalities that need both heat and electrical power. An
analytical approach has been developed...
