To make low grade lumber into high-valued products, finger-jointing is a widely
used method in the timber industry. In certain situations, chip-out occurs degrading the
quality of the joint. To better understand the machining process, a beam-type
dynamometer based on strain gages was designed to analyze the dynamic cutting forces...
Anaerobic digestion of lipid-extracted algal biomass has been proposed as a method to
recover and recycle nutrients in algal biofuel systems. The purpose of this study was to quantify recoverable nitrogen and phosphorus from anaerobically digested C. vulgaris. Recoverable nutrients were deemed those present in the liquid phase of anaerobic...

L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
The fifth volume of a five-volume series is presented. The contents are arranged under the following chapter headings: (1) Purification, (2) Effects on Materials, (3) Heaters and Coolers, (4) Radiators, Condensers, and Boilers, and (5) Applications.
The second volume of a five-volume series is presented. The contents are arranged under the following chapter headings: (1) Fluid Mechanics of Liquid Metals, (2) Liquid-Metal Heat Transfer, (3) Intermediate Heat Exchangers, and (4) Steam Generators.
The purpose of this research was to determine if differences
existed in mathematical skills needed for entry-level employment in
selected electricity-electronics occupations in Oregon. The four
primary objectives of the study were to:
1. Identify mathematical skills from task analyses of key
electricity-electronics occupations.
2. Validate the identified mathematical skills....
The application of laser generated ultrasonics was first
demonstrated in the mid-seventies and has shown good potential
when applied to isotropic materials. However, its use with
composite materials is still in the early stages of development.
This study explores the potential for application of laser
generated Rayleigh and Lamb waves...
