The present work presents a model based on fuzzy logic tools to predict and simulate the hot metal temperature in a blast furnace (BF). As input variables this model uses the control variables of a current BF such as moisture, pulverised coal injection, oxygen addition, mineral/coke ratio and blast volume, and it yields as a result of the hot metal temperature. The variables employed to develop the model have been obtained from data supplied by current sensors of a Spanish BF. In the model training stage the adaptive neurofuzzy inference system and the subtractive clustering algorithms have been used.
Since 1928, hemagglutinins have been known to exist in saliva; however, they have not been utilized as evidence in criminal investigations because in the past, techniques for measuring them have not been sufficiently sensitive. In this paper we describe improved techniques for detecting salivary hemagglutinins and report initial results obtained with these methods. The stability of salivary hemagglutinins at several different temperatures was examined in liquid samples and in dried stains on filter paper, cigarette butts, and envelope flaps. Our observations indicate that salivary hemagglutinins may be sufficiently stable, over periods of one to several days at ambient room temperatures, to be of value to forensic science investigators. The results of the hemagglutinin assay are not affected by the age or sex of the sample donor. Because salivary hemagglutinins can be used to determine ABO blood type, analyses of this kind can serve as an important confirmatory test which the forensic serologist can use in conjunction with salivary agglutinogen determinations.
The 60 MHz IH NMR spectra of clenbuterol, 1, have been studied in CDC13 solution with the achiral shift reagent, tris(6,6,7,7,8,8,8-hepta-fluoro-2,2-dimethyl-3,6-octanedionato)europiur(IIII), 2, and the 511 Copyright 0 I V X Y by Marcel I k k k e r .

Use of 3 resulted in observable enantiomeric shift differences, AAd, for the %-butyl, NHzf benzylic CH and the aryl proton signals. Values of A A d as high as 135.1 Hz (2.25 ppm) and 86.5 Hz (1.44 ppn) were seen for the methine and aryl protons, respectively, with a solution 0.1035 molal in 1 and a a:& molar ratio of 0.551. The aryl resonance is especially well suited for direct optical purity determinations of 1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
