the present paper compares full kinetics mechanisms in numerical modelling of porous radiant burners (prb), with their reduced forms. the two most frequently used mechanisms of methane combustion (gri3.0 and miller) were selected and their effects were examined on temperature, species concentration, burning speed, and pollutant emission. while the findings of numerical simulation of prb show fi...

The objective of this paper was to investigate the extraction process of tanshinone IIA and its mechanism of induction of gastric cancer SGC7901 cell apoptosis. Extraction process of tanshinone IIA was optimised by orthogonal experimental method, and its effect on gastric cancer SGC7901 cell apoptosis was observed using MTT assay and electron microscopy. The optimum extraction process of tanshi...

We study the question of auction design in an IPV setting characterized by ambiguity. We assume that the preferences of agents exhibit ambiguity aversion; in particular, they are represented by the epsilon-contamination model. We show that a simple variation of a discrete Dutch auction can extract almost all surplus. This contrasts with optimal auctions under IPV without ambiguity as well as wi...

This paper reports on solvent-extraction studies of Ni(II) from sulfate solutions with LIX 84I (2-hydroxy-5-nonylacetophenoneoxime) as the extractant. The extraction of metal depends on the equilibrium pH of the aqueous phase and the extractant concentration. The transfer of metal follows a cation exchange-type mechanism: Ni2+ + 2HA --> NiA2 + 2H+. Extraction varies with the nature of the dilue...

This paper describes a novel methodology to perform bilingual terminology extraction, in which automatic alignment is used to improve the performance of terminology extraction for each language. The strengths of monolingual terminology extraction for each language are exploited to improve the performance of terminology extraction in the other language, thanks to the availability of a sentence-l...
