Some synthetic efforts in small ring chemistry

Creator:: Lam, Luke Kwok Tung
Abstract:: Cyclopropylcyclobutene was prepared via the intermediate dicyclopropylcarbinyl carbene which was generated by the thermal decomposition of the sodium salt of dicyclopropylketone p-toluenesulfonylhydrazone. The successive thermal isomerization of cyclopropylcyclobutene to 2-cyclopropyl-1, 3-butadiene and to vinylcyclopentene was studied. Kinetic data were obtained for the cyclopropylcyclobutene to 2-cyclopropyl-1, 3-butadiene isomerization in the gas...

Alkylation studies on Hagemann's ester: an approach to the synthesis of the trisporic acids

Creator:: Sung, Wing Lam
Abstract:: Sequential alkylation of Hagemann's ester with methyl and methallyl halides has been studied. Treatment of Hagemann's ester with methyl iodide and sodium ethoxide gave a mixture of 21 and 25 in a ratio of 4:1. Alkylation of 21 with methallyl chloride and potassium t-butoxide afforded a mixture of 37 and...

A method of seismic design for prestressed concrete highway bridge girders

Creator:: Lam, Kwok To
Abstract:: The effects of vertical ground motion are particularly significant in the design of highway bridge girders. Conventional codes do not recommend methods for solving the problem. The intent of this work is to suggest an approach for such design. A set of curves for velocity spectra which are the average...

Dose of reality : what can we learn from educational and veterinary pet owners to guide more effective environmental stewardship of pharmaceutical and personal care products (PPCPs)?

Creator:: Lam, Jennifer
Abstract:: Improper disposal of unused human and pet pharmaceuticals and personal care products (PPCPs) are an emerging public and watershed health threat around the world. Although some waste stream reduction programs such as PPCPs "take-back" exist, there is limited research in current programs on reducing the entry of PPCPs into the...

Exploration of statistical methods for synthesizing the effects of variable-retention harvesting on multiple taxa

Creator:: Lam, Tzeng Yih
Abstract:: Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...

Object detection in biological images using a search-based framework

Creator:: Lam, Michael
Abstract:: This thesis addresses a basic problem in computer vision, that of semantic labeling of images. Our work is aimed at object detection in biological images for evolutionary biology research. In particular, our goal is to detect nematocysts in Scanning Electron Microscope (SEM) images. This biological domain presents challenges for existing...

Analytical model of GaAs MESFET output conductance with frequency and temperature dependent parameters

Creator:: Lam, Steven C. F.
Abstract:: The output characteristics of a conventional GaAs depletion-mode MESFET device have been investigated. One of the important parameters of the small-signal GaAs MESFET model, g[subscript ds] (output conductance), is shown to be frequency and temperature dependent. Variations in g[subscript ds] are a serious problem in many analog and digital circuits...

G, a language based on demand-driven stream evaluations

Creator:: Placer, John R.
Abstract:: A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demonstrate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and...

Biological control of purple loosestrife Lythrum salicaria by two chrysomelid beetles Galerucella pusilla and G. calmariensis

Creator:: Schooler, Shon
Abstract:: In the first part of this study we monitored the development of biological control of purple loosestrife Lythrum salicaria over a six-year period at Morgan Lake in western Oregon. In 1992, two beetles, Galerucella pusilla and G. calmariensis (Coleoptera: Chrysomelidae), were released to control the wetland weed at this test...
