Mechanism of Flake Drying and Its Correlation to Quality
… of the drying and bending properties of wood flakes. Three species (southern yellow pine, sweetgum, and yellow-poplar) were tested. Experiments on flake drying and effect of flake properties (cutting direction and dimension) and an external factor (temperature) were used to evaluate the flake …

Influence of Flake Morphology on Fluvial Transportation and Site Formation Interpretation
… device, I test the ways morphology affects a flake's transportation in flowing water. Many archaeological sites are located near fluvial environments where flowing water can potentially alter debitage assemblages. Previous researchers have studied the relationship between flake morphology and …

The processing and characterization of aluminum boride flake-reinforced aluminum matrix composites
AlB$\sb2$ flakes in an aluminum matrix offer the potential for greatly increased composite mechanical and wear properties because of their high aspect ratio, very high mechanical properties and good wetting to the aluminum matrix. This thesis describes, for the first time, an approach to the …

Manufacture and synthesis of a dark micro magnetic flake powder for forensic application
… a novel method for synthesis of a dark magnetic flake powder for detecting latent fingerprint has been developed. Even though, flake powders ,of aluminium, brass and highly reflective magnetic iron flake are already in use in crime scenes , it is highly desirable to develop a suitable darker …

Investigations of flakeboard mat consolidation
The response of a flake mat to the mechanical stress applied during consolidation is a function of mat structure, raw material properties and the environmental conditions created during pressing. This research project was aimed at improving the understanding of raw material behavior during the …

Changes in Oriented Strandboard Permeability During Hot-Pressing
… for panel "blowing". This research considers how flake thickness, flake alignment and changing mat density during hot-pressing influences OSB mat permeability, through its thickness and in the plane of the panel. Some previous research exists but it fails to address the affects of horizontal and …

A technology analysis of the U.S. Atlantic blue crab (Callinectes sapidus) processing industry
… of crab and season on the yields of lump, top flake, bottom flake, and claw and total meat were examined. The effects of cooking time and method and storage time on meat yield was also determined. During summer, male crabs yielded more lump, claw, and total meat than female crabs, and clean …

The development of sub-micro filler enhanced polymer composites
Sub-micro silica flakes and graphite reinforced polymer composites have been developed in this research. The sub-micro polymer composites are designed to overcome problems associated with nanocomposite technology. Apart from the high cost of production, the other major problem in nanocomposites is …

Detection, activity and resistance to thermal inactivation of peroxidase in the blue crab (Callinectes sapidus)
… in fresh and pasteurized lump, claw and flake meat of both male and female blue crabs was determined spectrophotometrically. Activity was greatest in the flake and least in the claw. Male crabs usually exhibited a greater initial activity (λ 0D 460/min) than did females of equal size. The …
