Entrance and exit region friction factor models for annular seal analysis
(1988)
The Mach number definition and boundary conditions in Nelson's nominally-centered, annular gas seal analysis are revised. A method is described for determining the wall shear stress characteristics of an annular gas seal ...
Sequence requirements of the SV40 early polyadenylation signal
(1988)
Polyadenylation of eukaryotic messenger RNA molecules consists of a two step reaction; cleavage of the primary transcript and step-wise addition of adenylic acid residues to the newly generated 3' OH group. The complex ...
Estimating multiphase flow functions in porous media from dynamic displacement experiments
(1988)
In this work, the estimation of relative permeability and capillary pressure from the data of dynamic displacement experiments was investigated. These properties are used extensively to predict the behavior of petroleum ...
The relationship of global self-esteem to the self-enhancement and self-consistency motives
(1988)
This study was designed to demonstrate that global self-esteem moderates reactions to violations of self-expectancies. Aronson & Carlsmith (1962) found that subjects whose low performance expectancies were disconfirmed by ...
A study of imbibition, germination and emergence of MAR cotton as influenced by soil physical properties
(1988)
Uniform germination and subsequent emergence of seedlings is the first and probably the most important factor that could affect final yield of a crop. In order to better understand the impact of physical conditions in the ...
Reverse osmosis concentration of orange juice : membrane modeling and performance
(1988)
Membrane concentration was modeled using similitude and dimensional analysis. Pertinent variables selected by this methodology were used to determine a series of dimensionless products to describe and model mass transport ...
Cross-synergism of cellulases from different sources
(1988)
Bioconversion of cellulose has great potential for applying large quantities of fermentable feedstocks which can be converted to fuels and commodity chemicals. To achieve maximum conversion of celluose in enzymatic hydrolysis ...
Investigation of the development of ultrahigh-strength Portland cement concrete (UHSC) consolidated by statically applied high confining stress systems
(1988)
Large size (12-in. cubes) specimens of ultrahigh-strength portland-cement concrete and mortar were successfully produced by using a high-pressure confining mold (12-million-pound total load capacity) designed, developed, ...
An event-oriented hourly precipitation model
(1988)
A simulation model of hourly rainfall amounts was developed to provide hourly precipitation input to a water balance model. The hourly rainfall model consists of four parts: (1) daily rainfall occurrence, (2) event rainfall ...
