Modern studies of atmospheres, oceans, and Earth and planetary systems require a good knowledge of basic chemical principles. This book provides a clear, concise grounding in these principles. Undergraduate and graduate students with little formal training in chemistry can work through the chapters, and the numerous exercises, within this book before accessing more advanced texts in atmospheric chemistry, geochemistry, and the environmental sciences. Basic Physical Chemistry for the Atmospheric Sciences covers the fundamental concepts of chemical equilibria, chemical thermodynamics, chemical kinetics, solution chemistry, acid and base chemistry, oxidation-reduction reactions, and photochemistry. This new edition has been updated and revised from the first edition. In a companion volume entitled Introduction to Atmospheric Chemistry (2000, Cambridge University Press) Peter Hobbs provides an introduction to atmospheric chemistry itself, including its applications to air pollution, acid rain, the ozone hole, and climate change. Together these two books provide on ideal introduction to atmospheric chemistry for a variety of disciplines.

Rembrandt van Rijn (1606-69) transcends any period or social milieu: he is one of the world's great masters and though his works reflect the confidence of newly independent Holland, his vision extends fat beyond these narrow confines. A deeply perceptive artist (his many self-portraits show his continued interest in the study of human nature), he sought to go beyond superficialities, to endow his biblical paintings, historical narratives, genre scenes and portraits with psychological depths hitherto unknown in Dutch painting. Impatient with conventionally stiffly posed group portraits, he produced such masterpieces as The Night Watch, The Anatomy Lesson of Dr Tulp and The Staal Meesters, while his studies of Saskia, his wife, and his mistress Hendrickje Stoffels reveal his deeply sensuous, compassionate nature. For this new, updated edition, Michael Kitson, Director of the Paul Mellon Centre in London, has revised his highly successful book in the light of the most recent scholarship on Rembrandt, making this the ideal survey of the career of a much-loved genius.

Few artists of this century have exercised so wide an influence as Paul Klee (1879-1940). He was one of the most inventive and prolific of the modern masters, working in a dozen different styles, each of which he made uniquely his own, so that a work from his brush is unmistakable in any style. The forty-eight full-page colour plates in this book illustrate the unparalleled way in which he combined unrivalled imaginative gifts with supreme technical and formal proficiency, from the playfulness of such early pictures as Red and White Domes to the more threatening, bitter satire of the later work. Accompanying the plates are extensive notes and an authoritative introduction, which discusses Klee's life and the development of his thought and achievement. Douglas Hall is the former Director of the Scottish National Gallery of Modern Art, Edinburgh and an acknowledged expert on the art of Paul Klee. His essay on the artist, first published in 1977, bas here been revised, expanded and updated, to make this an invaluable introduction to an extraordinary painter.

Paul Durand-Ruel redefined the role of the art dealer. An exceptional entrepreneur and precursor of the international art market scene, he established a network of galleries between Paris, London, Brussels, and New York, and organized international traveling exhibitions. The first to recognize the talent of the Barbizon School artists and then the impressionists, and confident in his role championing their art, Paul Durand-Ruel established the careers of visionary artists including Pierre-Auguste Renoir, Claude Monet, Alfred Sisley, Berthe Morisot, and Mary Cassatt. This book-fully revised and updated by the Durand-Ruel estate-is an indispensable reference for understanding the artistic circles and the art market of the nineteenth century. Retracing the dealer's life from 1831 to 1922, it features more than sixty illustrations including archival documents and reproductions of works of art, a selection of articles and letters, a list of the principal exhibitions and paintings he displayed, as well as a biographical timeline, family tree, and indexes to key figures, artists, and artworks.

"Rothery does an excellent job of synthesizing the research inspired by the Voyager missions into a coherent description of outer solar system geology." -Jonathan I. Lunine, Sky & Telescope "A highly readable, respectably accurate and complete nontechnical summary of planetary satellites for general and scientific audiences." -Paul M. Schenk, Icarus "Rothery brings these satellites to life." -David Hughes, New Scientist. "The depth and authority of the treatment of physical geological processes makes this a good introduction to the outer satellites for undergraduate students, while the clarity of the text ensures that things do not become too complicated for less expert readers." -Lionel Wilson, Times Higher Eduation Supplement. Extensively revised and updated, this new edition of this acclaimed geological guide to the outer solar system includes results and close-up color and black-and-white images from both the 1995-1999 Galileo mission to Jupiter and the Voyager space probe. Rothery explains the geological aspects of the major satellites of the outer planets, from Jupiter to Neptune and the Pluto-Charon system. In particular he shows how tectonic and volcanic processes, driven by heat from within, have shaped the rigid outer layers of these worlds. Rothery also discusses the similarities and differences among them and the ways in which they resemble Earth-like planets.

The central theme of Green Plants is the astonishing diversity of forms found in the plant kingdom, from the simplicity of prokaryotic algae to the myriad complexities of flowering plants. To help the reader appreciate this remarkable diversity, the book is arranged according to generally accepted classification schemes, beginning with algae (both prokaryotic and eukaryotic) and moving through liverworts, hornworts, mosses, fern allies, ferns and gymnosperms to flowering plants. Copiously illustrated throughout with clear line diagrams and instructive photographs, Green Plants provides a concise account of all algae and land plants, with information on topics from cellular structure to life cycles and reproduction. The authors maintain a refreshingly cautious and objective approach in discussions of possible phylogenetic relationships. Newly emerging information on features of plants known only as fossils is included, providing as complete a history as possible of the plant kingdom. Throughout the book there are many references to ultrastructural and physiological features which relate growth and form to current concepts in the study of plant development. This new edition has been completely updated to reflect current views on the origin of the major groups of plants and includes information arising from more recently developed techniques such as cladistic analyses. As such, it provides an up-to-date and timely resource for students of botany, and also for researchers needing a comprehensive reference to the plant kingdom.

Camille Pissarro (1830-1903) was not only a central figure in the Impressionist movement, but a major influence on the development of modern art. He was the only artist to exhibit at ail eight of the Impressionist exhibitions between 1874 and 1886, and his letters are a fascinating and invaluable source of information on the theoretical aspects and practical implications of Impressionism. Pissarro's career touched that of an extraordinary number of his contemporaries, to whom he was often a teacher and always a friend. In his early years he worked with Monet; in the 1870s he painted in close friendship with Cézanne; he was a guide for Gauguin, whom he introduced to the Impressionist group; and in the 1880s bc flirted with Neo-Impressionism with Seurat. This marvellously illustrated book charts the evolution of his painting, and celebrates his compositional brilliance, technical skill and innovatory approach. Forty-eight full-page colour plates illustrate the extraordinary quality of Pissarro's work from ail periods, and these combined with Christopher Lloyd's illuminating text constitute a superb introduction to the artist. Christopher Lloyd is the Surveyor of the Queen's Pictures. His essay on Pissarro, first published in 1979, bas been revised and updated, with the addition of commentaries to each plate, written by Amanda Renshaw, and a wide selection of comparative illustrations.

To fathom the complex culture of China is a daunting task, but Hu Wenzhong and Cornelius Grove, in this substantially revised and updated edition of their popular book, have risen to the challenge. They provide a practical and sensitive cross-cultural analysis of Chinese culture along with insights into how best to communicate and interact with Chinese people. As the economic and diplomatie climate in China has changed, the frequency of contact between Chinese and Americans has increased in all areas : business, academic, scientific, professional, personal and cultural, making this book even more valuable. Relying on Hu's knowledge of his native Chinese culture and Grove's American perspective from his substantial experience in China, Encountering the Chinese will enable Westerners to establish more productive and rewarding relationships with the Chinese, both inside and outside the PRC. As in the first edition, the authors retain fondamental information on basic Chinese values, cultural norms, and mindsets and identify the cross-cultural factors that often lead to failed business negotiations, embarrassing faux pas and misunderstandings when Americans and other Westerners encounter the Chinese. In this second edition they have added a discussion of economic changes and the gradual demise of state-owned companies, and they give special attention to the shift among young urban professionals and businesspeople from traditional collectivist values toward individualism and a market economy mentality. There is also a new section for American women working in China.

The Italian Yearbook of Human Rights 2015 provides a dynamic and up-to-date overview of the measures Italy has taken to adapt its legislation and policies to international human rights law and to comply with commitments voluntarily assumed by the Italian Government at the international level. The 2015 Yearbook surveys the activities of the relevant national and local Italian actors, including governmental bodies, civil society organisations and universities. It also presents reports and recommendations that have been addressed to Italy in 2014 by international monitoring bodies within the framework of the United Nations, the Council of Europe and the European Union. Finally, the Yearbook provides a selection of international and national case-law that casts light on Italy's position vis-à-vis internationally recognised human rights. "Italy and Human Rights in 2014 : the Challenge of National/International Constitutional Synergism" is the focus of the introductory section of the Yearbook. The complex network of monitoring actions carried out by the supranational bodies, and the relative reporting requirements Italy must meet, can only be viewed in the context of reciprocal exchange and strengthening between the provisions enshrined in the national Constitution and international human rights law. The Italian Agenda of Human Rights 2015 represents an updated orientation tool intended to support the commitment taken by the Italian Government in the framework of the second Universal Periodic Review (October 2014) before the UN Human Rights Council.

Ce livre sur Ansible s'adresse aux administrateurs de systèmes Unix qui souhaitent découvrir les différentes fonctionnalités spécifiques de cet outil DevOps permettant la configuration centralisée de serveurs et applications. A l'aide d'exemples concrets, l'auteur apporte au lecteur les connaissances nécessaires pour bien comprendre l'intérêt de son utilisation. Certains prérequis sur le langage YAML ou l'utilisation du protocole SSH sont un plus pour une utilisation efficace d'Ansible. Dans les premiers chapitres, l'auteur aide toutefois le lecteur à les acquérir pour qu'il puisse tirer le meilleur profit de la lecture du livre. Les chapitres qui suivent traitent des différents mécanismes d'Ansible avec une approche de difficulté progressive. Les premiers mécanismes permettent ainsi d'administrer de façon classique les serveurs (Unix ou Windows) alors que les suivants nécessitent des notions plus avancées, notamment sur la programmation Python. Le lecteur y découvre alors comment créer un inventaire, comment réinjecter des informations provenant de sources existantes (ESX, AWS, Docker...) ou comment créer des playbooks. La création de rôles Ansible est également traitée ainsi que quelques bonnes pratiques à suivre (analyse de code et test avec Molecule à l'aide de Podman ou Docker). A côté des notions purement orientées Ansible, certains chapitres sont consacrés au déroulement du déploiement d'une application MediaWiki. Le lecteur étudie ainsi les problématiques de parallélisation des tâches, l'introduction d'un répartiteur de charge Haproxy et le lancement en séquence des opérations permettant de réaliser les mises à jour avec un impact minimal (rolling update). L'optimisation des tâches sera également un point important avec la mise en place de Mitogen. La suite du livre détaille plus particulièrement la personnalisation d'Ansible. La restitution d'informations (mécanismes de callback et découverte de ARA), l'écriture de modules pour la gestion d'opérations, les filtres Jinja ou encore la création d'actions sont ainsi étudiés. Enfin, l'auteur présente dans les derniers chapitres la problématique de la création de machines virtuelles, classiques (via l'hyperviseur ESX/VMware/vCenter) ou dans le cloud (avec AWS), l'utilisation de containers containers Podman/Docker avec Ansible, le pilotage d'applications dans un cluster Kubernetes ainsi que la création d'un opérateur.
