Several experiments were undertaken to investigate the mechanism of
photodechlorination of pentachlorobenzene. The thermal methoxydechlorination
reaction of pentachlorobenzene was studied. In DMSO at 50 °C sodium
methoxide reacts smoothly with pentachlorobenzene to give three
tetrachloroanisole isomers. A second-order kinetic plot for this reaction is linear to
high precision, indicating that...
We give a new characterization of elements in the Veech group of a translation surface. This provides a computational test for Veech group membership. We use this computational test in an algorithm that detects when the Veech group is a lattice (has co-finite area), and in this case computes a...
We show that Pappus Curves, introduced by R. Schwartz to study his dynamical system in the real projective plane generated by iterated applications of the classical Pappus Theorem, are algebraic exactly in the linear case. Our approach is to use properties of projective curves such as singular points, genus, number...
This study examines the impact of the recently constructed
limited- access highway, Interstate 5, on agricultural land in Linn
County, Oregon. More specifically it scrutinizes the quality and
quantity of the land relinquished to the highway right -of -way; the
effects on field boundaries, connectivity, mobility, drainage, land
use, miscellaneous...

A THESIS
Purpose
The purpose of this study was to make a comparative analysis of
student attitudes and learning in relation to the selected academic
subject of English when it is applied to certain Oregon occupational
clusters. The occupational clusters selected were agriculture,
electricity-electronics, industrial mechanics, and stenographersecretarial
occupations.
Method
The comparisons...
We use the theory of continued fractions over function fields in the setting of hyperelliptic curves of equation y²=f(x), with deg(f)=2g+2. By introducing a new sequence of polynomials defined in terms of the partial quotients of the continued fraction expansion of y, we are able to bound the sum of...
