The Anatomical Therapeutic Chemical (ATC) classification system, recommended by the World Health Organization, categories drugs into different classes according to their therapeutic and chemical characteristics. For a set of query compounds, how can we identify which ATC-class (or classes) they belong to? It is an important and challenging problem because the information thus obtained would be ...

The laser, an acronym for light amplification by stimulated emission of radiation, is a source of nearly monochromatic, coherent, electromagnetic radiation that propagates as a beam. The chemical laser is a type of laser system that is driven by the release of energy during a chemical reaction. Chemical lasers are usually large, high power devices that integrate chemical delivery systems, a sup...

During chemical reactions, molecules interact to produce new molecules. Some of the reaction mechanisms are very close to the way gene combine to produce new genes. Like the classical genetic crossover operator, chemical crossover occurs when two molecules exchange the atomic material they are composed of. Molecules do so in order to produce new and more stable molecules. Several differences ex...

has been done of late years on the chemistry of pathological processes. The subject of Chemical Pathology is in its infancy, but it is fairly certain that the future of Pathology and even of Medicine will be closely bound up in it. Hitherto Pathology has been concerned chiefly with morphological questions, and rightly so, for the morphological problems are much easier to solve than the chemical...

The book’s first few chapters deal with an introduction to bioinformatics, sequence analysis, and the diverse Internet resources currently available. The following chapters guide the reader through the databases of BLAST: BLASTN, BLASTP, BLASTX, and TBLASTN. Each chapter is set up to conduct you through a particular example query (or two), and is supplemented with specific screen shots from the...

The corrosion protection of petroleum storage tank is important for safety work in petroleum depot. Precise prediction of soleplate corrosion may reflect the security state of a storage tank, and it can provide scientific references to the anti-corrosion and maintenance in safety management. Grey Model GM (1,1) in the Grey Theory is a good prediction method based on small volume of original dat...
