Constructive specification

Another generalization uses referential (material) symmetric Piola-Kirchhoff stress and Green strain tensors in place of the stress and strain tensors used in the small deformation theory. These tensors have components relative to a fixed reference configuration, and the theory of Section 5.2 carries over intact when small deformation quantities are replaced by their referential counterparts. The referential formulation has the advantage that tensor components do not change with relative rotation between the coordinate frame and the material, and it is relatively easy to construct specific constitutive functions for specific materials, even when they are anisotropic. 

The referential formulation is translated into an equivalent current spatial description in terms of the Cauchy stress tensor and Almansi strain tensor, which have components relative to the current spatial configuration. The spatial constitutive equations take a form similar to the referential equations, but the moduli and elastic limit functions depend on the deformation, showing effects that have misleadingly been called strain-induced hardening and anisotropy. Since the components of spatial tensors change with relative rigid rotation between the coordinate frame and the material, it is relatively difficult to construct specific constitutive functions to represent particular materials.

In order to complete this snapshot of the processes currently available for treating HWW, several case studies from the literature are reported below they all detail recent dedicated WWTPs constructed specifically for HWWs in different countries. 

A process that was no more than a laboratory phenomenon when the Office of Saline Water was authorized in 1952 has been rapidly developed to the point where it is now one of the most economical processes for the conversion of brackish water to fresh. This process, electrodialysis, was selected for the third demonstration plant. It will be located at Webster, S. D. The Bureau of Reclamation Laboratories in Denver, Colo., prepared the specifications for this plant which will be designed to produce 250,000 gallons of fresh water per day. Operating on water containing between 1500 and 1800 parts of salt per million parts of water, this plant will remove more than 1 ton of salt daily to produce product water with less than 500 parts of salt per million parts of water which is required to meet U. S. Public Health Standards for good drinking water. Construction specifications for this plant were available August 1, and sealed bids will be opened on October 4, 1960. 

Neither cargo vessels nor tank vessels have too many requirements associated with fire safety, and the key issues covered in their chapter (Chapter 20) are construction specifications and active fire protection. However, the code also states that interior finish and furnishings in exits and exit accesses must meet the requirements of Chapter 8 and that accommodation spaces must meet the requirements of Chapter 10 (and these vessels are rarely sprinklered). 

Chemical properties that reflect the tendency of a chemical to partition between phases have been constructed specifically for environmental fate applications. These specialized properties are known as partition coefficients. The parameter that is a measure of a chemical s tendency to partition between water and air is known as the dimensionless Henry s constant (KH), determined by the ratio of the...

Fluorinated carbonyl compounds may be employed in condensation reactions to stereo- and regioselectively construct specifically fluorinated materials. The fluorinated reactants may be utilized as either the nucleophilic or electrophilic reaction partners. 

The contributions to the relaxation energy of an isolated molecule, designated as intramolecular in character, E (intra), arise from two sources (4, 6). Electronic relaxations generate energies E (intra) = l-2eV whereas atomic relaxations yield E (intra) = 0.1-0.2eV. The electronic contributions are built inio the semiempirical CND0/S3 model by construction. Specifically, the procedure of determining the model parameters by fitting PES data for exanq>lary molecules (benzene, furan, pyrrole) provides a... 

The powder obtained with the MHQ technique, which has to be maintained below 140 K to prevent further reaction, is more difficult to handle than that produced by the RFQ technique because of its finer structure. To apply the spectrocopies listed above to such a powder, one often has to construct specific adaptations to sample holders and/or sample compartments, in particular, to get the powder where required, without warming during handling and operation.
