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...
متن کاملQualitative 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...
متن کاملComparative Genome Sequence Analysis of Choristoneura occidentalis Freeman and C. rosaceana Harris (Lepidoptera: Tortricidae) Alphabaculoviruses
The complete genome sequences of Choristoneura occidentalis and C. rosaceana nucleopolyhedroviruses (ChocNPV and ChroNPV, respectively) (Baculoviridae: Alphabaculovirus) were determined and compared with each other and with those of other baculoviruses, including the genome of the closely related C. fumiferana NPV (CfMNPV). The ChocNPV genome was 128,446 bp in length (1147 bp smaller than that ...
متن کاملApplication 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...
متن کاملQualitative Theory and Chemical Explanation
Roald Hoffmann and other theorists claim that we we ought to use highly idealized chemical models (“qualitative models”) in order to increase our understanding of chemical phenomena, even though other models are available which make more highly accurate predictions. I assess this norm by examining one of the tradeoffs faced by model builders and model users — the tradeoff between precision and ...
