The junction-field effect transistor has been improved technically,
so it is appropriate in analog switching applications. In this
paper, use of a junction FET as an analog switch is described.
Feedthrough of current from the gate control voltage...

The detection of limit cycles may be accomplished in several
ways. This thesis presents a numerical method for detection when
the system is described by the Van der Pol equation.
Two numerical integration methods are used to increase the
accuracy...

Hens were artificially inseminated at 8:00 a.m., 4:00 p.m.
and 11:50 p.m. Fertility was found to be significantly lower after
8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations
for 2 to 6 days, 2 to 9 days and 10 to 17 days...

Various simple mathematical models have been used to investigate dengue transmission. Some of these models explicitly model the mosquito population, while others model the mosquitoes implicitly in the transmission term. We study the impact of...

Sexual conflict over mating can result in sex specific morphologies and behaviors that
allow each sex to exert control over the outcome of reproduction. Genital traits, in
particular, are often directly involved in conflict interactions. Via...

There is a growing consensus that anthropogenic warming will impact soil organic matter (SOM). Globally, soil contains 2-3 times more carbon (C) than plants, and like plants, temperature induced change of SOM could have significant climate...

The typical coho salmon life history has been characterized by juvenile fish that spend their entire first year in freshwater habitats before migrating into estuaries as smolts. However, reports of early migrating coho fry (age 0), including...

Epichloë typhina, a fungal endophyte of
cool season grasses, is heterothallic and an obligate
out-crosser. In areas of endemism, its spermatia are
moved between stromata of the two opposite mating
types through egg-laying activities of Botanophila...

Despite holding substantial ecological value, wetlands in the United States have experienced a significant decline in both area and function over the past century with the majority of freshwater wetland loss attributed to agricultural conversion....

The mapped area lies between the Wallowa Mountains
of northeastern Oregon and the Seven Devils Mountains of
western Idaho. Part of the Snake River canyon is included.
A composite stratigraphic section includes at least
30,000 feet of strata. Pre-...

FORTRAN is readily feasible to translation into ALGOL since
they share many common features. Most of the features that are
unique to FORTRAN can be translated by restricting them somewhat.
The translator will handle explicit declarations of each...

Solid solution alloying was employed in an attempt to produce some
relatively ductile form of beryllium. If the c/a ratio could be significantly
altered, it was felt new or different slip systems could be activated. The
following elements were...

An abundant fruiting of a black morel was
encountered in temperate northwestern New South
Wales (NSW), Australia, during a mycological survey
in Sep 2010. The site was west of the Great Dividing
Range in a young, dry sclerophyll forest dominated...

A study of the population ecology of Columbia River fall chinook
salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt
to determine the cause of a serious decline in this run which occurred
in the early 1950's. Fluctuations in...

OBJECTIVE: The 75% of older adults with multiple chronic conditions are at risk of therapeutic competition (i.e. treatment for
one condition may adversely affect a coexisting condition). The objective was to determine the prevalence of potential...

Rhizopogon subgenus Villosuli are the only
members of the genus known to form an ectomycorrhizal
relationship exclusively with Pseudotsuga. The
specificity of this host relationship is unusual in that
Rhizopogon is broadly associated with several...

A model for analytical study of the attitude stability of an
orbiting satellite consists of a rigid body whose mass center is constrained to move at constant speed in a circular path about the
center of an inverse-square force field. The body is...

The major nutrient requirements of the blue-green alga Anabaena
spiroides Klebahn were investigated. It was hoped that the results would allow the development of a balanced culture medium in
which the alga would exhibit rapid growth and retain...
