Circulation and temperature effects on the development and distribution of the eggs and larvae of the Antarctic krill, Euphausia superba : a modeling study
(1989)
An existing three-dimensional time-dependent circulation model was adapted to investigate the circulation in the South Shetland Islands - Bransfield Strait region. The simulated circulation distributions show seasonal ...
Pre-referral intervention : implementing a workshop model to reduce the rate of inappropriate referrals among regular education teachers
(1989)
The purpose of this study was to design and implement a workshop series model advocating pre-referral intervention. The emphasis was upon developing a set of procedures that would create more efficient screening practices ...
A parallel machine for the unification algorithm : design, simulation, and performance evaluation
(1989)
Unification, which has applications in databases, expert and knowledge-based systems, and natural language and image processing, is known to be the most repeated operation in logic and PROLOG interpreters. Slow execution ...
Electrolysis of hydrogen sulfide in aqueous solutions and molten salts
(1989)
An analysis of the chemical and electrochemical reactions in aqueous sulfide solutions indicated that the electrolysis of hydrogen sulfide in an alkaline solution will yield elemental sulfur and hydrogen without the ...
Burnett apparatus for measurement of cross second virial coefficients study case : ethane-propane at 350, 400 and 450 K
(1989)
An experimental apparatus, based on the Burnett mixing experiments, was designed and constructed for measuring the cross second virial coefficient (B12). In this isothermal experiment, two pure fluids are fed to separate ...
A new method for kinetic studies of fast radical rearrangements : development and applications
(1989)
An indirect method for studying the kinetics of fast radical rearrangements has been developed. The method employs N-hydroxypyridine-2-thione ("PTOC") esters as radical precursors and hydrogen atom transfer from thiophenol ...
Change masters in schools : a description of innovative strategies in Texas and Michigan
(1989)
For some time, the school has been seen as the organization that must be at the center of change. It is education's worksite; it is where the action is. It is where individuals can be challenged to become a community of ...
A biosystematic study of the Schizachyrium scoparium complex
(1989)
Population samples of Schizachyrium scoparium, collected from Texas (vars. divergens, frequens, littorals, and virile) and New Mexico (var. neomexicanum), and herbarium specimens (including type specimens of Andropogon ...
Decline curve analysis for real gas wells with non-Darcy flow
(1989)
Isochronal testing of gas wells suggests that high velocity flow in wells containing hydraulic fractures results in an additional pressure drop down the fracture that is flow rate dependent. In addition, wellhead pressures ...
A study in extensional tectonics
(1989)
Boudin wavelength to thickness ratios are determined by: (1) the value of the power-law exponent in the layer, (2) the ratio of layer strength to confining medium strength; and (3) the ease of slip on the layer-medium ...
