Scanning tunneling microscopy of organic monolayers at the fluid- solid interface

Creator:: Marty, Valerie J.
Abstract:: More that just magnificent views of atoms and molecules, Scanning Tunneling Microscopy, STM, images have the potential to answer some fundamental questions relating to surface molecular dynamics and bonding characteristics of localized species versus more common analytical tools that provide average of bulk sample information. A special feature of the...

Free amino acids in cultured higher marine fungi

Creator:: Peters, James E.
Abstract:: The free amino acid content of the intracellular pools in higher marine fungi was determined by thin-layer and gas-liquid chromatography. The organisms investigated include: Ascomycetes; Nais inornata, Leptosphaeria oraemaris, Corollospora maritima, Haligena elaterophora, Halosphaeria mediosetigera, Halosphaeria appendiculata, Halosphaeria quadriremis, Lignincola Laervis and Remispora hamata, and Fungi Imperfecti; Zalerion maritimum and...

A phytochemical study of Achlys triphylla (Smith) DC., (Berberidaceae)

Creator:: Born, Alvin Edmund
Abstract:: Achlys triphylla, a member of a medicinally active family containing alkaloids, was examined phytochemically to determine its possible value as a source of medicinal agents. Pharmacological testing of the crude ethanol extract exhibited a competitive inhibition of acetylcholine and histamine. Purification of alkaloid 'A' from the crude ethanol extract and...

Ganglionic circulation and regulation of cardiovascular activity in Aplysia californica

Creator:: Furgal, Sheryl M.
Abstract:: Neurons in the abdominal ganglion of the marine mollusk, Aplysia californica , appear to respond directly to changes in blood flow and oxygen tension within the ganglion. When circulation through the ganglion is reduced, the spontaneous activity of some identifiable neurons are excited while others are inhibited. Many of the...

Survey of graduates and undergraduates of North Douglas School District to determine needed improvements in career education

Creator:: Smith, Richard Alan
Abstract:: School systems have an important responsibility to continuously examine and review their educational programs to determine if the programs satisfy the needs of the youth they serve. Systematically collected data derived from former and present students can enable the school system to appraise its effectiveness in fulfilling the aim it...

Spatial patterns of anomalous runoff to precipitation ratios for watersheds within the contiguous United States arranged by level one ecoregions

Creator:: Pittman, Jason W.
Abstract:: Mean annual runoff to precipitation (R/P) ratios were generated for 966 watersheds within the contiguous United States. The watersheds were plotted using Arc View GIS and used as part of an overlay analysis with Level 1 U.S. ecoregions. The ratios were statistically evaluated to determine anomalous R/P conditions within the...

Fruit quality evaluation of strawberries (Fragaria ananassa) grown in California and Oregon

Creator:: Jetti, Rajesh R.
Abstract:: Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...

Biosynthetic studies of fungal diterpene antibiotics

Creator:: Yao, Qingmei
Abstract:: The isoprenoid pathway is one of the major biosynthetic pathways of secondary metabolites. Isoprenoids with a C₂₀ skeleton are known as diterpenoids and are derived from the common precursor, geranylgeranyl diphosphate (GGPP). This dissertation describes approaches to discover the diterpene synthase enzymes which provide the backbone structures for pleuromutilin and...
