Statistical mechanics of polymer systems. [Annual] progress report, [1989--1990] (open access)

Statistical mechanics of polymer systems. [Annual] progress report, [1989--1990]

Dynamic Monte Carlo simulations were performed to obtain the dynamic scaling behavior of isolated, self-avoiding chains below the theta temperature. Simulations were conducted using both face-centered cubic and body-centered cubic lattice models, which use only one-bead elementary motions. Temperature effects were simulated by a nearest neighbor (square-well) interaction potential with a minimum energy {epsilon}. The relaxation times of the normal modes and the scaling exponents obtained are consistent with the predictions of Brochard and DeGennes for gel mode formation. The scaling exponent relating relaxation times to mode number showed high correlation with coil density. Dynamic scaling results were model independent for a given value of {mu}{phi} where {mu} is the coordination number minus one and {phi} = {minus} {epsilon}/k{sub B}T.

D0 Cryo Ventilation Fan Controls and Monitoring (open access)

D0 Cryo Ventilation Fan Controls and Monitoring

This engineering note describes how exhaust fan 6 (EF-6) and exhaust fan 7 (EF-7) are controlled and monitored. Since these two fans are a vital link in the ODH safety system, they will be monitored, controlled and periodically operated by the programmable logic controller (PLC). If there should be a fault in the ventilation system, the PLC will print a warning message to the cryo control room printer and flash a descriptive warning on the ODH/ventilation graphics page. This fault is also logged to the Xpresslink graphics alarm page and to an alarm history hard disk file. The ventilation failure is also an input to the auto dialer which will continue it's automatic sequence until acknowledged. EF-6 delivers 13000 C.F.M. and is considered emergency ventilation. EF-7 delivers 4500 C.F.M. and will run 24 hrs a day. Both ventilation fans are located in an enclosed closet in the TRD gas room. Their ductwork, both inlets and outlets run along side the pipe chase, but are separated by an airtight wall. Their combination motor control starter cabinets are located in the TRD room in plain visible sight of the fans with the closet door open. The fans have signs that state they …

Overview of Proposed Geothermal Development in Hawaii (open access)

Overview of Proposed Geothermal Development in Hawaii

During the four hours of the public meeting held by the State Department of Business and Economic Development (DBED) in Maui in November 1989, not one of the 200 persons present spoke in favor of geothermal development on the Big Island to supply power to Oahu. However, we were all sure after the meeting that the State would proceed on its course to develop the project in spite of any public concerns. This situation we find incredible considering there are many unanswered questions on a subject of paramount importance to the economic and environmental well being of all of us. Our concerns are well expressed in the editorial of The Maui News, December 10, 1989 . We wish to set the record straight with some facts from an economic, financial and utility planning viewpoint, recognizing also the potentially serious social, health and other environmental impacts.
