Describes a thin film rectangular dielectric waveguide and its laboratory use. Discusses the theory of uniaxial thin film waveguides with mathematical expressions and the laboratory procedures for a classroom experiment with diagrams. (Author/YP)

Uses the process of normalization in the Cartesian coordinate system which entails radial projection onto a transect to compare different compositions of minerals. Warns that the ternary diagram should not be used as a framework for calculations. (MVL)

Discusses the origin of the catastrophic event as to whether it was an episodic process or of extraterrestrial or endogenous origin. Develops a model of a volcanic mechanism to produce shocked quartz like those found in the Deccan basalts. (MVL)

Describes a method for making holograms viewable in white light without the problem of vibrations. Presents diagrams which show the arrangement for construction, viewing procedures, and a device for generating holograms. A list of supplies is included. (RT)

Presents an experiment to measure the threshold limit of the adhesion of water. Discusses types of thresholds and pseudo thresholds. Provides 13 examples of thresholds in science. (MVL)

This syllabus describes the course objective, examinations and grading, term papers and class presentation, and references. Provides a table of assignments and schedule describing topics and contents. (YP)

Discusses a wall chart, "The Standard Model of Fundamental Particles and Interactions," for use in introductory physics courses at either high school or college level. Describes the chart development process, introduction and terminology of particle physics, components of the chart, and suggestions for using the chart, booklet, and…

Suggests a change in physical chemistry courses to use a slightly more complicated but significantly more useful generalization of the simple freezing point depression law. Lists reasons for the change and presents the treatment of solid-liquid equilibria where solid-solution is allowed. Provides a mathematical treatment. (MVL)

Explains the need, general guidelines, expectations, and advantages of student involvement in research at the undergraduate level. Lists selected research projects conducted by students at Burlington County College. (RT)

Evaluates seven courseware packages covering the topics of fluid dynamics, kinetic theory, and thermal properties. Discusses the price range, sub-topics, program type, interaction, time, calculus required, graphics, and comments of each courseware. Selects some packages based on the criteria. (YP)

Provides an overview of the Computer-Aided Management of Emergency Operations (CAMEO) model and its use in the classroom as a training tool in the "Hazardous Chemical Spills" course. Presents six problems illustrating classroom use of CAMEO. Lists 16 references. (YP)

Provides an overview of the "Hazardous Waste Management Graduate Certificate" program at Wayne State University. Describes four required courses and nine optional courses. Discusses the development of a Master program and the curriculum of the Master program. (YP)

This study was undertaken to determine whether a biology preparatory course given at an urban community college was helping students to develop the proper skills and background necessary to successfully complete follow-up courses in biology. Data indicated a mathematics score was the main discriminator between pass/fail groups of the preparatory…

Described are methods for locating, collecting and culturing ladybird beetles. Included are necessary equipment for feeding and breeding the insects and modifications for various species found in Great Britain. Overwintering spots of various species are also listed. (CW)

Discusses the use of linear regression methods to extrapolate experimental data. Describes the method of averages and two weighted least squares. Calculates the error range of each method. (YP)
