Back-calculation of length-at-age from otoliths and spines is a common technique employed in fisheries biology, but few studies have compared the precision of data collected with this method for catfish populations. We compared precision of back-calculated lengths-at-age for an introduced Ictalurus furcatus (Blue Catfish) population among 3 commonly used cross-sectioning...
Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...
The black grass bug genus Irbisia Reuter was revised. Over 18,000
specimens were examined and information concerning the biology, host
plant and distributional relationships of the species was compiled.
In addition to external characters, the male claspers and vesica, and
the female dorsal libiate plate of the bursa copulatrix and...
Avian encephalomyelitis virus-infected chick embryo homogenate
was precipitated with polyethyleneglycol 6000 (PEG), extracted
with fluorocarbon, concentrated by ultrafiltration, and purified by
isopycnic gradient centrifugation. The physical and chemical properties
of the purified virus were studied. The examination of purified
avian encephalomyelitis virus (AEV) with electron microscopy using
negative stain revealed...
Nonpoint sources of pollution are being recognized
nationwide as a significant threat to groundwater quality.
In Oregon, groundwater supplies in several areas have been
affected by contamination possibly caused by nonpoint
sources associated with agricultural activities, on-site
sewage disposal, and inadequate hazardous materials
management in urban areas. State groundwater protection...
The purpose of this study was to determine the effects of the
Delphi Technique on two types of judgment; factual judgment and value
judgment. Other considerations were the effect of the process on
mean response and variability of response.
In testing the Delphi Technique this study arrived at five
definite...
