This work set out to examine the potential contribution of five aliphatic lactones, γ-nonalactone, γ-decalactone, γ-dodecalactone, δ-decalactone and δ-dodecalactone to stone fruit aroma in beer. This work consists of three related studies; lactone olfaction thresholds, additive/synergistic aroma effects and a gas-chromatography-mass-spectrophometry method of analysis. First was the determination of these...
RNA tumor viruses, such as avian myeloblastosis virus (AMV)
and MC29 virus, cause malignant transformation of the cells they infect.
Transformed cells are able to continually produce progeny virus
particles.
Evidence is given that RNA-dependent RNA polymerase is present
in virus infected cells. RNA-dependent RNA polymerase isolated
from AMV-infected myeloblasts...
The volatile flavor fraction of lightly milled wheat grown in
eastern Oregon was isolated for study by two methods: steam distillation
under vacuum and steam distillation at atmospheric pressure.
The sample obtained under vacuum was extracted with ether
which was then evaporated to yield the desired wheat essence.
Steam distillation...
With the increased production and use of double knit fabrics
made from textured filament polyester, homemakers have become
concerned over procedures for care that can be successfully carried
out in the home. The purpose of this study was to determine what
effects wash water temperatures and drying methods have on...
The Communication Decency Act became law in 1996 and was
immediately challenged on Constitutional grounds. It was subsequently declared
unconstitutional based on the First Amendment guarantee of free speech. Using
Fantasy Theme Analysis, an analysis of the dramatic elements of the key players
was accomplished. The dramatic elements of Overall...
The creating of pattern in woven fabrics by placing design on the
warps and/or wefts before they are woven is ancient. Primary
examples of these textiles are ikat, which is a resist dyeing technique,
and chine, in which design is painted or in some way printed on the
tensioned warp...
The development of an effective infectious
hematopoietic necrosis virus (IHNV) vaccine depends on a
better understanding of the antigenic structure and
variation among isolates. Three objectives to elucidate
this were: (1) to generate a panel of antigenic
derivatives of the IHNV glycoprotein by monoclonal
antibody-mediated selection of neutralization-resistant
variant viruses,...
Twenty mentally retarded teen-age girls living at Fairview Hospital and Training Center in Salem, Oregon, were selected to be included in this study. The purpose of the study was to attempt to determine if institutionalized mentally retarded teen-age girls are able to benefit through a class dealing with personal grooming...
The purpose of this study was to answer the following question: What was the
perceived value to planners of incorporating information from ecotourists about their
perceived needs in the standard system presently being used to plan interpretation?
The Ecotourist Needs Assessment (ETNA) process was proposed as an external needs
assessment....
