Phytochemical profiles and antioxidant activity of four historical
grape accessions (‘Kuzu Kuyrugu’, ‘Miskali’, ‘Erkek Miskali’, and
‘Kirmizi Kismis’) grown in Igdir province located in Eastern Anatolia
Region of Turkey were examined. The amount of vitamin C,
organic acids (citric acid, tartaric acid, malic acid, succinic acid and
fumaric acid), sugars...
The ethyl acetate extract of the culture filtrate of the marine Ascomycete,
Leptosphaeria oraemaris (Linder) yielded a novel metabolite
designated by the common name leptosphaerin. An x-ray crystallographic
structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)-
3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine
47 and D-mannitol 44. Oxidation of 47 followed...
Few discoveries of any importance have been the result of a moment's happy coincidence; rather have they been the fruit of many hours of tedious thought and experiment. This is especially true in the realm of organic chemistry. Here, where progress is made only by the most painstaking experimentation, extensive...
The focus of postcolonial studies has shifted in the last decade or so from a struggle over history, the narratives of winners and losers—as recorded by the winners and resisted by the losers—to a struggle over geography. Power inequities formerly embodied in Manichean conceptualizations (Colonizer/Colonized, Oppressor/Oppressed, Occidental/Oriental, Self/Other, First World/Third...
Isolated populations of four reindeer lichen species and varieties co-occur in a unique relict prairie habitat at Mima Mounds Natural Area Preserve, southwest Washington State, USA. The prairie is the type locality for mima mounds, unusual geologic features providing topographical variation that influences vegetation patterns. Reindeer lichens (Cladonia subgenus Cladina)...
Forest communities in the central portion of Oregon's western Cascades are arrayed along moisture and temperature gradients. With the aid of reconnaissance data and a computerized ordination technique, 23 forest communities have been provisionally recognized in two distinct forest zones, the Tsuga heterophylla (300 to 1050 m in elevation) and...
The purpose of this study is to investigate the direction of future
Korean industrial engineering education and to suggest how U.S.
experiences can guide Korean developments. The leading indicator
concept, correlation coefficients are utilized.
The following statistical relationships were developed and the
following educational and practical industrial engineering trends in...
"The general objective of research . . . was to determine mechanisms that control the production dynamics of benthic plants and associated epiphytes in Netarts Bay relative to physical processes and changing patterns of nutrient distribution. . ."
Under defined cultural conditions, zygotes of the brown alga
Fucus distichus L. Powell divide synchronously to form two-celled
embryos at approximately 24 hours after fertilization. These two
cells differ from one another in gross morphology, ultrastructure,
cytochemistry, and developmental fate. Cytochemical staining and
autoradiography indicated that a sulfated polysaccharide was...
A study to determine the relationship between plant species and eight terrain variables and between thirty-one vegetation types
and the terrain variables was conducted in a 4, 000 square mile area
south and east of Tucson, Arizona. The eight terrain variables
included elevation, parent material, macrorelief, landform type,
drainage density,...
This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...
The ability of N,N'-diphenylurea (DPU) to substitute for cytokininactive
adenine derivatives in promoting callus growth of Phaseolus lunatus
and Nicotiana tabacum has been examined. In general, DPU stimulated
callus growth of P. lunatus at high concentrations and the growth of
most callus tissues was irregular, while the response of tobacco...
Crown gall infected and healthy Kalanchoe pinnata (Lam.)
Persoon plants were analyzed for soluble amino acids. Specifically
the amino acids in young leaf, mature leaf, stem, root, and gall
tissues were quantitatively measured. The plants were inoculated
with the bacterium, Agrobacterium tumefaciens (Smith and Townsend)
Conn., on one side of...
