The Nearctic species of the genus Sympherobius
Banks are revised. Seventeen species are recorded from
the region. Two new species, S. constrictus and S.
quadricuspis are described from California and Arizona
respectively. Four new specific synonyms are proposed
(junior synonym(s) first): S. brunneus Nakahara and S.
stangei Nakahara = S....
This paper discusses the theoretical design parameters of
photographic data recording systems associated with atmospheric
research radar. Practical considerations modify these theoretical
results. The design of a recording system employed on the Range
Height Indicator (RHI) scope of the weather Radar Set AN/CPS-9
atop McCulloch Peak, Oregon, illustrates the optimization...
Experimental crosses between Rana pretiosa pretiosa Baird
and Girard and Rana cascadae Slater, resulted in viable hybrids.
Reciprocal differences at the time of fertilization are indicated. A
high level of success in producing viable hybrids can be obtained if
Rana pretiosa pretiosa is the female of the parent species, The...
Forced vital capacity lung expiration examinations of nonsmoking
and cigarette-smoking male sample populations were compared to
determine if the 75 to 85 percent segment was a more sensitive test
of early lung dysfunction. The nonsmoking population was composed
of 240 men who were tested for values of forced vital capacity...
A comparative investigation of the phenotypic properties of environmental and clinical strains of the lactose-positive human pathogen, Vibrio vulnificus, revealed that they are indistinguishable in traits commonly used for identification in clinical and public health laboratories. It has also been confirmed that there are other strains of undefined Vibrio spp.,...
"Expert systems" is an area in the field of
artificial intelligence which attempts to encode an
"expert's" heuristic knowledge and reasoning ability into
a computer program. The purpose of this study is to
investigate the applicability of using an "expert system"
in a closed-loop automatic control system.
An "expert system"...
Benthic samples were collected during the summer, winter and
spring seasons from upper Yaquina Estuary, a region used by Georgia-
Pacific Corporation for log dumping and storage. Samples came from
an active log dump and storage areas as well as areas not associated
with log handling activity. The samples were...
