in this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. distributions of absorption coefficients across the spectrum  are obtained from the hitran2008 database. the full-spectrum k-distribution method is used to deal with the non-gray part of the problem, while the gray radiation calculations are performed using the planck ...

Abstract In this paper, I argue that the distinction between standard and non-standard pragmatic implications, originally used to differentiate among types of conversational implicatures, applies family contents—traditionally referred as ‘presuppositions’—that exhibit projective behaviour. Following scholars working within Question Under Discussion model communication, distinguish two implicati...

In the study of the occurrence and distribution of collagen in normal and pathological tissue and its formation and development in the embryo there has been need for aq accurate method to determine this substance in small amounts of tissue. Spencer, Morgulis, and Wilder (1) devised a method based on conversion of collagen to gelatin followed by the determination of the nitrogen of the gelatin p...

Most available results on optimal decisions under partial information are derived “separation”. But this principle does not always hold. We derive a non-standard first order condition of optimality from principles when signal extraction and policy must be jointly determined. This allows us to solve model fiscal where separation apply. Tax smoothing prevails in normal times, but taxes respond st...

A full-scale treatment system for swine manure was developed to eliminate discharge to surface and ground waters and contamination of soil and groundwater by nutrients and heavy metals, along with related release of ammonia, odor, and pathogens. The system greatly increased the efficiency of liquid-solid separation by polymer injection to increase solids flocculation. Nitrogen management to red...

The standard procedure for the determination of chlorine in organic compounds of mercury consists in decomposition of the material, separation of mercury and determination of chlorine as chloride. Decomposition of the sample could be achieved by wet mineralization [1,2], ignition in a stream of oxygen [3—7] or nitrogen [8], ignition in a flask with oxygen [9], etc. [10, 11]. Chlorine and mercur...

A sensitive and specific assay for the simultaneous quantification of trihexyphenidyl and its hydroxylated metabolite in plasma and urine is described. The method is based on the extraction of the drugs with an organic solvent and separation on a 3% OV-17 Chromosorb Q column in a gas chromatograph equipped with a nitrogen-phosphorus detector. The procedure employs SKF 525 A as the internal stan...
