On average, 60% of the world's people and cargo is transported by vehicle that move on rubber tires over roadways of various construction, composition, and quality. The number of such vehicles, including automobiles and all manner of trucks, increas
Chemoinformatics: Theory, Practice & Products covers the theory, commerciallyavailable packages and applications of Chemoinformatics. Chemoinformatics isbroadly defined as the use of information technology to assist in the acquisition,analysis and m
Modern biology has become an information science. Since the invention of a DNA sequencing method by Sanger in the late seventies, public repositories of genomic sequences have been growing exponentially, doubling in size every 16 months—a rate often
We have been exploring experimental conditions to achieve the exfoliation of the layered niobate phase K4Nb6O17 using alkyl amines. In this work, the exfoliation process of the niobate acidic form H2K2Nb6O17 was evaluated in aqueous solutionmedia us
This book was designed with one thing in mind: the way people learn the C# language. Seminar audience feedback helped me understand the difficult parts that needed illumination. In the areas where I got ambitious and included too many features all a
Registration, indexing and searching of chemical structures in relational databases is one of the core areas of cheminformatics [1,2]. Research on the topic goes back to the 1960s and probably before that [3]. However, little detail has been publish
