Il volume, al momento l’unico in italiano sui PLC S7-1200 e S7-1500, presenta le principali caratteristiche dei due PLC Siemens attualmente in produzione. Nel testo viene prima analizzato l’aspetto hardware e poi, in modo più dettagliato, ma con un linguaggio tecnico sempre accessibile, il software di gestione. La teoria è sviluppata in modo semplice e corredata di esempi che rendono più facile la comprensione. Le tracce degli esercizi sono definibili affini all’impianto. Successivamente vengono esposte e sviluppate, sempre con esempi, le principali tecniche di programmazione avanzata. L’opera è divisa in moduli e al termine di ognuno sono proposti un buon numero di domande ed esercizi molto utili per la revisione e il consolidamento dell’argomento sviluppato. Sono presenti anche numerose fi gure che illustrano l’utilizzo e le funzioni del software TIA Portal.

Communities Of Practice

This book presents a theory of learning that starts with the assumption that engagement in social practice is the fundamental process by which we get to know what we know and by which we become who we are. The primary unit of analysis of this process is neither the individual nor social institutions, but the informal 'communities of practice' that people form as they pursue shared enterprises over time. To give a social account of learning, the theory explores in a systematic way the intersection of issues of community, social practice, meaning, and identity. The result is a broad framework for thinking about learning as a process of social participation. This ambitious but thoroughly accessible framework has relevance for the practitioner as well as the theoretician, presented with all the breadth, depth, and rigor necessary to address such a complex and yet profoundly human topic.

Global warming is changing the world as we know it. Climate change can have catastrophic impacts in numerous cities across the world. It is time for us to react – quickly and effectively. The European Community (EC) has been leading the fight against climate change, making it one of its top priorities. We have introduced the most ambitious targets of their kind, known as the “20/20/20 by 2020” initiative within the “Climate Action and Renewable Energy Package.” As a result, European Member States have taken on a commitment to curb their CO emissions by at least 20% by 2020. 2 These targets are indeed commendable; however, they are only the start if we are to avoid the consequences of global warming. Whilst top level coordination from the European Institutions and Member State governments is vital, the role of mitigating and adapting to climate change at local level must not be forgotten. In fact, here cities, regions and their citizens play a significant a role. It is therefore vital they become directly involved in the climate change challenge. The European Commission therefore launched in 2008 a new initiative, the Covenant of Mayors, which brings together a network of European mayors in a voluntary effort to go beyond the European Union’s already ambitious targets. Half of our greenhouse gas emissions (GHGs) are created in and by cities.

This book reflects the research output of the Committee on the International Protection of Consumers of the International Law Association (ILA). The Committee was created in 2008, with a mandate to study the role of public and private law to protect consumers, review UN Guidelines, and to model laws, international treaties and national legislations concerning protection and consumer redress. It has been accepted to act as an observer not only when the UNCTAD was updating its guidelines, but also at the Hague Conference on Private International Law. The book includes the contributions of various Committee members in the past few years and is a result of the cooperation between the Committee members and experts from Australia, Brazil, Canada and China. It is divided into three parts: the first part addresses trends and challenges in international protection of consumers, while the second part focuses on financial crises and consumer protection and the third part examines national and regional consumer law issues.
