Abstract:

Context. We consider a weakly to moderately active comet and make the following simplifying assumptions: (i) The partial ionization frequencies are constant throughout the considered part of the coma. (ii) All species move radially outward with the same constant speed. (iii) Ion-neutral reactions affect the chemical composition of the ions, but ion removal through dissociative recombination with free electrons is negligible. Aims. We aim to derive an analytical model for the radial variation of the abundances of various cometary ions. Methods. We present two methods for retrieving the ion comp

Abstract:

We present two studies that investigated the adoption of visual/spatial and analytic strategies by individuals at different levels of expertise in the area of organic chemistry, using the Visual Analytic Chemistry Task (VACT). The VACT allows the direct detection of analytic strategy use without drawing inferences about underlying mental processes. The first study examined the psychometric properties of the VACT and revealed a structure consistent with the hypothesis that it consists of two sub-scales: visual/spatial and analytic. The second study investigated the performance of 285 participan

Abstract:

Victorian chemistry and Victorian political theory are both constructed around a foundational analytic unit: for the former, it is the atom, and for the latter, the individual. Because the latter construct was actually the more robust of the two, Victorian chemists used the resources of art and literature to lend individuality to atoms, while literary writers used chemistry to suggest that the category of the individual might be no more than a fiction of liberal theory.

Abstract:

ArgumentHistorians have accorded a privileged status to the analytic ideal of elements as a distinctive marker of “modern” chemistry. Boyle’s and Lavoisier’s have been used to characterize their modernity, which has in turn justified their status as the founding fathers of modern chemistry. It has been difficult, however, to establish a viable connection between these two fathers or the genealogy of their definitions. I argue in this paper that French didactic tradition gave rise to the definition Boyle stated in the Sceptical Chymist, or the analytic/philosophical ideal of elements. He did no

SummaryThis paper introduces the concept of bivariate structural regression analysis, a new technique which offers some advantages compared to the well-known structural relationship approach. The concept is not restricted to multivariate normal distribution, and without additional constraints the model remains identifiable in the bivariate case. A bivariate calibration line is developed first by the maximum likelihood method and then also distribution-free by applying rank statistics. Both estimation procedures coincide, if the distribution assumption is satisfied. Hence, the distribution-free

Abstract:

Analytical chemistry is deeply rooted in Europe. It started with the work of Liebig and Fresenius, among others. Then Kirchhoff, as father of spectroscopy, contributed to the development of the modern instrumental analysis techniques flourishing today. As soon as I started learning analytical chemistry at university, I fell in love with it. At that time, I could not explain why I wanted to become an analytical chemist. Having gained experience teaching and performing research in analytical chemistry, I know now that I am attracted to it because this branch of chemistry is what an apple means t
