The French chemist Marcelin Berthelot put forward a classical and by now an often cited sentence revealing the quintessence of the chemical science: "La Chimie cree son objet". This is certainly true because the largest number of molecular compounds were and are continuously synthesized by chemists themselves. However, modern computational quantum chemistry has reached a state of maturity that one can safely say: "La Chimie Theorique cree son objet" as well. Indeed, modern theoretical chemistry is able today to provide reliable results on elusive systems such as short living species, reactive intermediates and molecules which will perhaps never be synthesized because of one or another type o...
Chemistry is the science of substances (today we would say molecules) and their transformations. Central to this science is the complexity of shape and function of its typical representatives. There lies, no longer dependent on its vitalistic antecedents, the rich realm of molecular possibility called organic chemistry. In this century we have learned how to determine the three-dimensional structure of molecules. Now chemistry as whole, and organic chemistry in particular, is poised to move to the exploration of its dynamic dimension, the busy business of transformations or reactions. Oh, it has been done all along, for what else is synthesis? What I mean is that the theoretical framework ac...
Formal methods have been applied successfully to the verification of medium-sized programs in protocol and hardware design for some time. However, their application to the development of large systems requires more emphasis on specification, modeling, and validation techniques supporting the concepts of reusability and modifiability, and their implementation in new extensions of existing programming languages like Java. This book contains 20 revised papers submitted after the 10th Symposium on Formal Methods for Components and Objects, FMCO 2011, which was held in Turin, Italy, in October 2011. Topics covered include autonomic service-component ensembles; trustworthy eternal systems via evolving software, data, and knowledge; parallel patterns for adaptive heterogeneous multicore systems; programming for future 3D architectures with many cores; formal verification of object oriented software; and an infrastructure for reliable computer systems.
Evo Morales is one of the world's most controversial political leaders. His story is extraordinary: poor shepherd-boy, persecuted coca grower, self-professed admirer of Ché Guevara, hero of the anti-globalization movement, and first indigenous president of modern Latin America. The story of the social movement turned political party he is a part of -- the Movimiento Al Socialismo (MAS) -- is also exceptional: originally founded as a splinter of an ultra-right party, it was given as a gift for the coca growers after they had been banned several times for spurious reasons to register their own party, and went on to become an irresistible force for indigenous rights in Bolivia. In this insightful and revealing book, Sven Harten explains the success of the MAS and its wider consequences, showing how Morales has become the symbol for a new political consciousness that has entailed de-stigmatizing indigenous identities. In many ways, the analysis of Morales's political trajectory serves as a mirror for democracy in Bolivia. It reveals the challenge of squaring the rupture with a discredited past with the continuity of democracy and the aim of representing an entire society.
Advances in Heterocyclic Chemistry is the definitive series in the field - one of great importance to organic chemists, polymer chemists, and many biological scientists. Because biology and organic chemistry increasingly intersect, the associated nomenclature also is being used more frequently in explanations. Written by established authorities in the field from around the world, this comprehensive review combines descriptive synthetic chemistry and mechanistic insight to yield an understanding of how chemistry drives the preparation and useful properties of heterocyclic compounds. - Considered the definitive serial in the field of heterocyclic chemistry - Serves as the go-to reference for organic chemists, polymer chemists and many biological scientists - Provides the latest comprehensive reviews written by established authorities in the field - Combines descriptive synthetic chemistry and mechanistic insight to enhance understanding of how chemistry drives the preparation and useful properties of heterocyclic compounds
This volume contains fifty-six revised and extended research articles, written by prominent researchers participating in the congress. Topics covered include electrical engineering, chemical engineering, circuits, computer science, communications systems, engineering mathematics, systems engineering, manufacture engineering and industrial applications. This book offers theoretical advances in engineering technologies and presents state of the art applications. It also serves as an excellent source of reference for researchers and graduate students working with/on engineering technologies.
This open access book constitutes the proceedings of the 23rd International Conference on Fundamental Approaches to Software Engineering, FASE 2020, which took place in Dublin, Ireland, in April 2020, and was held as Part of the European Joint Conferences on Theory and Practice of Software, ETAPS 2020. The 23 full papers, 1 tool paper and 6 testing competition papers presented in this volume were carefully reviewed and selected from 81 submissions. The papers cover topics such as requirements engineering, software architectures, specification, software quality, validation, verification of functional and non-functional properties, model-driven development and model transformation, software processes, security and software evolution.
