In a conventional well-mixed fluidized bed the solids are almost
completely mixed and the residence time for individual particles may vary
between zero and infinity. For materials especially sensitive to the processing
time, a wide distribution of residence time is extremely undesirable. A multi-compartment
fluidized bed was proposed to minimize...

Abraham Heschel wrote that a philosopher's primary task was not merely to describe and judge the modes and facts of actual human behavior, but also to examine and understand the meaninq of those descriptions and judgements of modes and facts (Bella, 1978). Our values are critically tied to our structures...
Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...
This paper provides logit estimates of the probability that students will
cheat in a specific class using randomized response and direct question data in
two logit models. The results predict that there are several indicators of the
probability of cheating occurring in a class. These factors include both student
and...
The solution of coupled neutronic/thermal hydraulic nuclear reactor calculations
requires the treatment of the nonlinear feedback induced by the thermal hydraulic
dependence of the neutron cross sections. As a result of these nonlinearities, current
solution techniques often diverge during the iteration process. These instabilities arise
due to the low level...
Detailed subsurface structure contour maps and cross sections have shown the
northern Los Angeles basin to be underlain by a south facing monocline that is
complicated by secondary faults and folds. The monocline forms a structural shelf that
marks the northern boundary of the Los Angeles central trough. The monocline...
There is a widespread problem with looting and vandalism of cultural resources in the Pacific Northwest. To combat this problem law enforcement must have the assistance of the archaeological community. To be able to assist law enforcement, archaeologists and cultural resource specialists must have the proper training in cultural resource...
Stress analysis was performed to determine the maximum stress acting on a railcar coal support-bed, using COSMOS finite element and WFM micromechanics models. The fracture strength of polyurethane impregnated Kevlar 29 fabric, proposed for integration with the railcar structure, was determined experimentally by loading the impregnated coupons in a microcomputer...
