Tables for Qualitative Chemical Analysis

Simplified qualitative chemical analysis for urinary calculi.

OXALATE Stone powder (2-3 mg) is moistened on an ordinary glass slide with two to three drops of 20% nitric acid and is slowly heated over a small flame to dryness and then for a further 5-10 seconds but without charring. The following results may be noticed: (a) formation of a conspicuous reddish-brown froth indicating ammonium urate; (b) formation ofa flat purplish-brown layer, evidence of ur...

Analysis of Contingency Tables Bayesian Analysis of Contingency Tables

The display of the data by means of contingency tables is used in different approaches to statistical inference, for example, to broach the test of homogeneity of independent multinomial distributions. We develop a Bayesian procedure to test simple null hypotheses versus bilateral alternatives in contingency tables. Given independent samples of two binomial distributions and taking a mixed prio...

Qualitative analysis of an autocatalytic chemical reaction model with decay

In this paper, we revisit a reaction–diffusion autocatalytic chemical reaction model with decay. For higher-order reactions, we prove that the system possesses at least two positive steady-state solutions; hence, it has bistable dynamics similar to the system without decay. For the linear reaction, we determine the necessary and sufficient condition to ensure the existence of a solution. Moreov...

Application Qualitative Process Theory to Qualitative Simulation and Analysis of Inorganic Chemical Reaction

In this paper, we explored the possibilities of embedding Qualitative Reasoning techniques, the Qualitative Process Theory (QPT), and its techniques in the field of inorganic chemistry. The targeted field of implementation is in the Chemical Qualitative Simulation and Qualitative Analysis. The QPT is used to model the chemical reaction, behaviors, properties, principles and commonsense reasonin...
