Trends and sources of lead (Pb) aerosol pollution in the North Pacific rim of North America from 1850 to 2001 are investigated using a high-resolution (subannual to annual) ice core record recovered from Eclipse Icefield (3017 masl; St. Elias Mountains, Canada). Beginning in the early 1940s, increasing Pb concentration at...
Ocimum basilicum L. (sweet basil) is an essential oil producing crop used in culinary and fragrance applications. The objective of this controlled environment study was to evaluate the effects of organic and conventional fertilization (applied at two nitrogen rates, 150 and 250 kg N/ha) on plant growth, essential oil yield...
A major achievement in research supported by the Kluane Lake Research Station was the recovery, in 2001–02, of a suite of cores from the icefields of the central St. Elias Mountains, Yukon, by teams of researchers from Canada, the United States, and Japan. This project led to the development of...
Many hazelnut (Corylus avellana L.) cultivars
fail to thrive in vitro on standard growth medium and the
reasons for poor growth are not well understood. Our initial
study of five C. avellana cultivars showed that changes in
the mineral nutrients of Driver and Kuniyuki walnut
(DKW) medium, including doubling the...
We contrast the two approaches to ‘‘classical’’ signature change used by Hayward with the one used by us (Hellaby and Dray). There is (as yet) no rigorous derivation of appropriate distributional field equations. Hayward’s distributional approach is based on a postulated modified form of the field equations. We make an...
The divergence theorem as usually stated cannot be applied across a change of signature unless it is reexpressed to allow for a finite source term on the signature change surface. Consequently all conservation laws must also be ‘‘modified,’’ and therefore insistence on conservation of matter across such a surface cannot...
The divergence theorem in its usual form applies only to suitably smooth vector fields. For vector fields which are merely piecewise smooth, as is natural at a boundary between regions with different physical properties, one must patch together the divergence theorem applied separately in each region. We give an elegant...
Background: Pearl millet [Pennisetum glaucum (L.) R. Br.] is a widely cultivated drought-and high-temperature tolerant C4 cereal grown under dryland, rainfed and irrigated conditions in drought-prone regions of the tropics and sub-tropics of Africa, South Asia and the Americas. It is considered an orphan crop with relatively few genomic and...
Coal-bed natural gas production in the U.S. in 2012 was 1655 billion cubic feet (bcf). A by-product of this production is co-produced water, which is categorized as a waste product by the Environmental Protection Agency. The effects of varying concentrations of coal-bed methane (produced) water were studied in the greenhouse...
Pumping water from coal seams decreases the pressure in the seam and in turn releases trapped methane; this is the most common and economic method of methane extraction. The water that is pumped out is known as "coal-bed methane water" (CBMW), which is high in sodium and other salts. In...
We quantified the juvenile rearing and migratory patterns of individuals from a population of fall-spawning Chinook salmon Oncorhynchus tshawytscha in Oregon's Salmon River estuary using otolith microchemistry and microstructure. The study confirmed the daily periodicity of otolith growth increments in a natural fish population under field conditions and validated fundamental...
Most wild animals face concurrent challenges by multiple
infectious organisms, and immunological responses triggered by
some parasites may increase susceptibility to other infectious agents.
Immune-mediated interactions among parasites have been investigated
among individuals in a population, but less is known about
broader comparative patterns. We investigated the “macro-micro facilitation
hypothesis”...
This publication is the third in a series of circulars de signed to assist the graduate engineer in reviewing engineering subject matter in order to prepare for registration examinations. As in the first publication of the series, most of the illustrative problems are taken from recent examinations of the Oregon...

Micropropagation of hazelnut (Corylus avellana
L.) is typically difficult because of the wide variation
in response among cultivars. This study was designed to
determine the required mineral nutrient concentrations for
micropropagation of C. avellana cultivars using a response
surface design analysis. Driver and Kuniyuki Walnut
(DKW) medium mineral nutrients were...
This paper discusses moorage costs during the summer of 1974 for 13 coastal boat basins in Oregon, northern California, and southern Washington. A paper prepared for presentation at the winter meeting of the Pacific Coast Congress of Harbor Masters and Port Managers in Newport, Oregon, January 10, 1975.
A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations...
This article examines a subset of justice-involved persons with mental illness who have repeated contacts with law enforcement officers. Previous work has alluded to this sub-population—often termed “frequent fliers”—but little research has empirically examined its size and nature. This study proposes a method of identifying frequent fliers that is based...
In this paper we examine the effects of self-reported sexual orientation on substance abuse. Using data on a random sample of 6713 individuals in Washington State, this study examines causes and correlates of substance use by sexual minorities, an at-risk and treatment underserved population. Logistic regression results indicate homosexual orientation...
A stand of ponderosa pine (Pinus ponderosa) severely affected by Armillaria root disease was treated with five different levels of sanitation by root removal to reduce root disease losses in the regenerating stand. Treatments included the following: (1) all trees pushed over by machine, maximum removal of roots by machine...

In-line, optical sensing has been developed for on-combine measurement and mapping of grain protein concentration (GPC). The objective of this study was to estimate changes in costs and net returns from using this technology for segregation of the dark northern spring (DNS) subclass of hard red wheat (Triticum aestivum L.)...
The potato tuberworm, Phthorimaea operculella
(Zeller) (PTW), is one of the most important limitations to
potato, Solanum tuberosum L., productivity worldwide.
Leaves, stems, petioles and more importantly, potato tubers,
in the field and storage can be seriously affected. Due to the
relatively recent arrival of the PTWin the United States...
Sensor design and mission planning for satellite ocean color measurements requires careful consideration of the signal dynamic range and sensitivity (specifically here signal-to-noise ratio or SNR) so that small changes of ocean properties (e.g., surface chlorophyll-a concentrations or Chl) can be quantified while most measurements are not saturated. Past and...
OBJECTIVES: The current study examined disparities in smoking trends across African Americans and non-Hispanic whites in California.
METHODS: Data from the 1996 to 2008 California Tobacco Survey were analyzed to examine trends in smoking behaviors and cessation across African Americans and non-Hispanic whites.
RESULTS:
A decrease in overall ever and...
In a population of the European common toad Bufo bufo from a rural pond in the region of Lake Glubokoe Regional Reserve in Moscow province, Russia, unexplained mass mortality events involving larvae and metamorphs have been observed over a monitoring period of >20 yr. We tested toads from this and...
What is the nature of evolutionary divergence of the jaw skeleton within the genus Oncorhynchus? How can two associated bones evolve new shapes and still maintain functional integration? Here, we introduce and test a ‘concordance’ hypothesis, in which an extraordinary matching of the evolutionary shape changes of the dentary and...
Successful host cell colonization by the Q fever pathogen, Coxiella burnetii, requires translocation of effector proteins into
the host cytosol by a Dot/Icm type 4B secretion system (T4BSS). In Legionella pneumophila, the two-component system (TCS)
PmrAB regulates the Dot/Icm T4BSS and several additional physiological processes associated with pathogenesis. Because PmrA...
