DNA from the human squamous carcinoma cell line, SK-MES-1, and the
plasmids, pUC EJ6.6 containing H-ras oncogene, pSVc-mycl containing
cellular myc gene, pNRSac containing N-ras oncogene, pBR SV containing
SV40 virus DNA, pSV2-neu containing neu oncogene and pSV2-neo
containing neomycin resistant gene were used to transform Balb serum-free
derived mouse...
Dipterans of the family Ephydridae (shore and brine flies) are well
known for their ability to tolerate and thrive in a wide variety of
physically harsh circumstances. The immature stages of one such species
of this family, Ephydra hians, are characteristically limited in
distribution as benthic inhabitants of highly alkaline...
Seasonal abundance and life history traits were compared between populations of the brine fly Ephydra (Hydrokyrus) hians Say (Diptera:Ephydridae), from two western Great Basin alkaline salt lakes. Abert Lake, Oregon, has a relatively low salinity (20-30 g/1 total dissolved solids) and more co-inhabitant benthic species than the higher salinity Mono...
An information processing model of the problem-solving
performance of mechanical designers is presented for four design
tasks: conceptual assembly design, layout component design, detail
component design, and catalog selection. These tasks are organized
into six kinds of segments called episodes, which describe the goal
structure of the designer while performing...
This study is an archeological testing report for the Willamette
Mission Hospital Site. Landform analysis, photointerpretation and historical
research were integrated with anthropological theory for this
study.
The site is an invaluable data base to further the study of human
adaptability and cultural change. It should provide an excellent context...
Noise induced hearing loss is a subject of growing
concern. Over the past 15 years, several well-documented
studies have been completed which express the relationships
between industrial noise exposure and damage to normal and
pathological ears. This research has provided knowledge of
considerable importance to developing successful hearing
conservation programs....
