Citizen science (formally public participation in science research) has emerged in recent years as an innovative and interactive tool for engaging many diverse groups in science and research. Defined as the collaboration of science professionals and the public in science research, citizen science has tremendously improved the reach of science....
Zoos, aquariums and other free-choice/informal education settings offer the public opportunities to interact with live animals in exhibits through animal encounters and/or touch experiences designed to carry a conservation mission. Many of these institutions are accredited by the American Association of Zoos and Aquariums (AZA) and the World Association of...
The distribution of adult Pacific herring (Clupea harengue
pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by
depth and geographic area over 24 successive months during 1973-75.
From June through September, schools concentrated at 5- to 37-m
depths where zooplankton was abundant, and moderate currents were
present in a...
A liquid-extraction procedure for the concentration of zinc in
sea water was developed. The metal ion in sea water was chelated
with sodium diethyldithiocarbamate and extracted into an organic
solvent, methylisobutylketone, at the normal pH of sea water. A
back-extraction into HCl followed, providing a concentration of 30X
for the...
Shrews of the "Sorex vagrans species complex" were classified into
nine taxa on the basis of morphologic and morphometric analyses of
2,299 specimens from Washington, west of the Cascade Mountains in
Oregon, and in the Coast Ranges of California. In Washington, Sorex
monticolus setosus and S. m. obscurus occur west...
The objective of this study was to determine the distribution of
leakage radiation from two unshielded diagnostic-type X-ray tube
housings. This information was used to determine the shielding required
in the housings to bring them into compliance with the definition
of a diagnostic-type protective tube housing, as set forth by...
The purpose of this study was to examine self-perceived
success as experienced in a learning environment, and its association
with self esteem. The relationships between pretreatment-self
esteem, posttreatment-self esteem, and perceived success experienced
in a five-week clothing construction course were investigated.
Measures of perceived sewing ability, perceived success,
and course...
In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited
similar pH dependent solubilities, showing a minimum solubility at
about pH 8. Their solubilities varied with temperature, having a
positive enthalpy of solution. The effect of a...
