Plant pathogens and diseases are among the most significant challenges to survival that plants face. Disease outbreaks caused by microbial or viral pathogens can decimate crop yields and have severe effects on global food supply. Understanding the molecular mechanisms underlying plant immune response and applying this understanding to develop biotechnological tools to enhance plant defense against pathogens has great potential for moderating the impact of plant disease outbreaks. Plant Pathogen...

The aim of this book is to relate fluid flows to chemical reactions. It focuses on the establishment of consistent systems of equations with their boundary conditions and interfaces, which allow us to model and deal with complex situations. Chapter 1 is devoted to simple fluids, i.e. to a single chemical constituent. The basic principles of incompressible and compressible fluid mechanics, are presented in the most concise and educational manner possible, for perfect or dissipative fluids....

Aimed at senior undergraduates and first-year graduate students, this book offers a principles-based approach to inorganic chemistry that, unlike other texts, uses chemical applications of group theory and molecular orbital theory throughout as an underlying framework. This highly physical approach allows students to derive the greatest benefit of topics such as molecular orbital acid-base theory, band theory of solids, and inorganic photochemistry, to name a few. Takes a principles-based, group...

Colour is a sensation and as such it is a subjective and incommunicable quantity. Colour measurement is possible because we can create a correspondence between colour sensations and the light radiations that stimulate them. This correspondence concerns the physics of light radiation, the physiology of the visual process and the psychology of vision. Historically, in parallel to standard colorimetry, systems for colour ordering have been developed that allow colour specifications in a very...
