Com os avan os na tecnologia m dica, os materiais utilizados na presta o de cuidados dent rios s o uma rea de investiga o fascinante. O material restaurador ideal para os dentes ainda dif cil de encontrar. Mesmo ap s a introdu o de v rios materiais restauradores dent rios ap s a elimina o gradual da am lgama, o material mais testado e confi vel para muitos dentistas ainda o cimento de ion mero de vidro (GIC). As propriedades b sicas encantadoras deste material ajudam n o s no tratamento, mas tamb m na preven o. Por isso, era necess rio revisitar as suas vantagens b sicas e combin -las com tecnologias mais recentes, incluindo a nanotecnologia. Este livro apresenta a genealogia do GIC, incluindo a maior parte do trabalho de investiga o realizado atrav s da integra o de v rias nanopart culas no material, com o objetivo de manter as suas qualidades b sicas vantajosas e superar as falhas. A an lise detalhada ajudar os estudantes de gradua o e p s-gradua o em medicina dent ria a compreender os conceitos b sicos do material. Os profissionais da rea da medicina dent ria, bem como os pacientes conscientes de hoje, tamb m beneficiar o de informa es atualizadas sobre o material restaurador dent rio mais popular.

Mit den Fortschritten in der Medizintechnik sind die in der Zahnmedizin verwendeten Materialien ein faszinierendes Forschungsgebiet. Das ideale Material f r Zahnrestaurationen ist noch immer nicht gefunden. Auch nach der Einf hrung verschiedener Zahnrestaurationsmaterialien nach dem Auslaufen von Amalgam ist Glasionomerzement (GIC) f r viele Zahn rzte nach wie vor das bew hrteste und vertrauensw rdigste Material. Die grundlegenden faszinierenden Eigenschaften dieses Materials helfen nicht nur bei der Behandlung, sondern auch bei der Pr vention. Daher war es an der Zeit, seine grundlegenden Vorteile erneut zu betrachten und mit neueren Technologien, darunter der Nanotechnologie, zu kombinieren. Dieses Buch bietet eine Genealogie des GIC, einschlie lich eines Gro teils der Forschungsarbeiten, die durchgef hrt wurden, um verschiedene Nanopartikel in das Material zu integrieren, mit dem Ziel, seine grundlegenden vorteilhaften Eigenschaften zu erhalten und seine M ngel zu berwinden. Die detaillierte Analyse wird Zahnmedizinstudenten und Doktoranden ein grundlegendes Verst ndnis des Materials vermitteln. Zahn rzte und auch die heutigen informierten Patienten werden von den aktuellen Informationen ber das beliebteste Zahnrestaurationsmaterial profitieren.

Use this practical guide to successfully handle the challenges encountered when designing an enterprise data lake and learn industry best practices to resolve issues.When designing an enterprise data lake you often hit a roadblock when you must leave the comfort of the relational world and learn the nuances of handling non-relational data. Starting from sourcing data into the Hadoop ecosystem, you will go through stages that can bring up tough questions such as data processing, data querying, and security. Concepts such as change data capture and data streaming are covered. The book takes an end-to-end solution approach in a data lake environment that includes data security, high availability, data processing, data streaming, and more.Each chapter includes application of a concept, code snippets, and use case demonstrations to provide you with a practical approach. You will learn the concept, scope, application, and starting point.What You'll LearnGet to know data lake architecture and design principlesImplement data capture and streaming strategiesImplement data processing strategies in HadoopUnderstand the data lake security framework and availability modelWho This Book Is ForBig data architects and solution architects

A practical guide to help you tackle different real-time data processing and analytics problems using the best tools for each scenario About This Book • Learn about the various challenges in real-time data processing and use the right tools to overcome them • This book covers popular tools and frameworks such as Spark, Flink, and Apache Storm to solve all your distributed processing problems • A practical guide filled with examples, tips, and tricks to help you perform efficient Big Data processing in real-time Who This Book Is For If you are a Java developer who would like to be equipped with all the tools required to devise an end-to-end practical solution on real-time data streaming, then this book is for you. Basic knowledge of real-time processing would be helpful, and knowing the fundamentals of Maven, Shell, and Eclipse would be great. What You Will Learn • Get an introduction to the established real-time stack • Understand the key integration of all the components • Get a thorough understanding of the basic building blocks for real-time solution designing • Garnish the search and visualization aspects for your real-time solution • Get conceptually and practically acquainted with real-time analytics • Be well equipped to apply the knowledge and create your own solutions In Detail With the rise of Big Data, there is an increasing need to process large amounts of data continuously, with a shorter turnaround time. Real-time data processing involves continuous input, processing and output of data, with the condition that the time required for processing is as short as possible. This book covers the majority of the existing and evolving open source technology stack for real-time processing and analytics. You will get to know about all the real-time solution aspects, from the source to the presentation to persistence. Through this practical book, you'll be equipped with a clear understanding of how to solve challenges on your own. We'll cover topics such as how to set up components, basic executions, integrations, advanced use cases, alerts, and monitoring. You'll be exposed to the popular tools used in real-time processing today such as Apache Spark, Apache Flink, and Storm. Finally, you will put your knowledge to practical use by implementing all of the techniques in the form of a practical, real-world use case. By the end of this book, you will have a solid understanding of all the aspects of real-time data processing and analytics, and will know how to deploy the solutions in production environments in the best possible manner. Style and Approach In this practical guide to real-time analytics, each chapter begins with a basic high-level concept of the topic, followed by a practical, hands-on implementation of each concept, where you can see the working and execution of it. The book is written in a DIY style, with plenty of practical use cases, well-explained code examples, and relevant screenshots and diagrams.

This book examines the politics of rural development with special reference to watershed development interventions in the desert province of Rajasthan in India. Watershed development (and rainwater harvesting) is one of the most significant rural development interventions in rainfed areas of India since the early 1990s. A range of developmental actors including the state watershed department, international donors, NGOs and grassroots organisations are involved in sponsoring watershed development projects. Using multi-sited ethnography and conversational interviews with the deliverers as well as recipients of development, the book compares and contrasts the watershed interventions of the state and two different kinds of NGOs in Rajasthan. While conventional studies on watershed development have focused on the evaluation of ‘success’ or ‘failure’ of particular projects, whether implemented by the state or NGOs, the book moves beyond this narrow analytical gaze to look at the roles, agendas and interests of multiple development agencies, often partnering together and sometimes competing with each other as part of, what the author calls, the ‘watershed development regime’.Taking cue from watershed development and water conservation projects over the last two decades, the book engages with the larger question of ‘how’ of delivering development. It examines the complex processes of cooperation, competition, negotiations, contestations and conflicts between different stakeholders, including the agents of development and differently positioned rural social groups in the context of Rajasthan. The book demonstrates that the recent interventions in watershed development and rainwater harvesting have considerably shaped the politics of development in Rajasthan in a number of ways: by becoming a site for the remaking of the ‘state’ and its internal relations, by disturbing the local hegemony in the countryside, by creating new relations of patronage between diverse agents and recipients of development, by increasing the associational capacity as well as creating new conflicts (intra and inter village) and by initiating competition and cooperation between the various agents of development over control of local resources and power.
