Characterization of Minerals, Metals, and Materials 2018
This collection gives broad and up-to-date results in the research and development of materials characterization and processing. Coverage is well-rounded from minerals, metals, and materials characterization and developments in extraction to the fabrication and performance of materials. In addition, topics as varied as structural steels to electronic materials to plant-based composites are explored. The latest research presented in this wide area make this book both timely and relevant to the materials science field as a whole. The book explores scientific processes to characterize materials using modern technologies, and focuses on the interrelationships and interdependence among processing, structure, properties, and performance of materials. Topics covered include ferrous materials, non-ferrous materials, minerals, ceramics, clays, soft materials, method development, processing, corrosion, welding, solidification, composites, extraction, powders, nanomaterials, advanced materials, and several others.
Electrochemistry of N4 Macrocyclic Metal Complexes
This new edition describes the state of the art regarding metal complexes of N4-ligands, such as porphyrins and phthalocyanines. Volume 2 focuses on the electro assisted use of N4 complexes as biomimetic models for studying several biological redox processes. It focuses on molecular oxygen transport and catalytic activation to mimic monooxygenase enzymes of the cytochrome P450 in particular. It also examines N4 complexes’ use as catalysts for the oxidative degradation of various types of pollutants (organo-halides, for example) and residual wastes. The remarkable activity of these complexes towards a large number of significantly relevant biological compounds makes them excellent candidates as electrode modifiers for electrochemical sensing. This volume also discusses applications of N4 Macrocyclic Metal Complexes to photoelectrochemistry and photocatalysis, and concludes with an exciting section on Electrosynthesis of N4.

When God Gives Life a Purpose
When God gives life a purpose, everything is transformed, and the sun will always shine, even in the midst of winter! This is the author's personal account of her life journey, where she discovers her faith in God and the resilience to persevere. The book delves deeper than self-help, emphasizing living in Cod while facing life's adversities and triumphing over them. The studies were carried out with exceptional devotion to construct sound biblical solutions. The ideas display an innovative trait and uncover plentiful prospects. Their luminosity, perseverance, and capacity to convey meanings make them authentic spiritual gifts that are available to everyone and signify a condition to be unraveled. In general, the relationship between the Word and the idea promotes the relationship between new concepts, attitudes, and changes. The quality of the text is determined by the complex and enigmatic process of aligning the presented elements with the social-cognitive content. Reading is viewed as an intentional concept, where the participants are active agents who construct themselves and each other through dialogic exchanges.
Electronic commerce and digital services
THE DIGITAL ENVIRONMENT HAS NO BOUNDARIES. A new business model, product or technological service emerges all the time. Along with the facilitation and solutions brought by technological development, new problems, conflicts and litigation in social and economic relations also arise. Laws of several countries are not often able to keep up with the digital dynamism. Furthermore, there is not a consensus in international trade organisations on the concept of digital services and electronic commerce. That is the scenario in which the European Union has constantly developed rules to regulate the digital environment, ensuring and combining legal security and standardisation of rules with the pract...
Service Contracts in the Oil and Gas Industry
This book is written and edited by experts and academics already active in the oil and gas industry, and addresses students and practitioners alike. It aims to familiarize them with salient features of oil and gas service contracts. The book provides a concise description and, to a lesser extent, analysis of the main features of service contracts of the types commonly used in the oil and gas industry. Writers and editors come from different legal traditions and practice in different jurisdictions, including UK, Iran, Brazil and Mexico. Service contracts are as broad as their name suggests, comprising a wide array of contracts. However, a clear distinction exists between contracts where one party to the contract is a sovereign state or neither is. This has been the basis for organizing the present book in two parts.
The long and winding lawsuit
When transnational couples split, one of the parents wants to reestablish the status quo ante. But now there is a child. Rodrigo Meira brings to light this problem in Brazil and delivered the first research that has delved into the court files, with a view to understanding international abduction in Brazil. The author worked at the Brazilian Central Authority and is concluding his PhD in International Law, in which he examines Brazilian compliance, analyzing cases from 2002 to 2022 and interviewing other professionals who deal everyday with the problem. Meira shows what lies behind this procedural slowness, critically analyzing the culture of biased interpretation by procedural means. He als...
Spectral method for fatigue damage estimation with non-zero mean stress
This thesis consists of a fatigue study carried out on an aluminum alloy 2024-T3 in both time domain and frequency domain. Non-zero mean random signals of strain and stress are analyzed in time domain using usual Rainflow method and the damage is accumulated with the Palmgren-Miner rule, according to mean stress equations. The signals are analyzed in frequency domain using the power spectral density and the probability density function. The spectral domain analysis does not consider the negative effect of the mean stress in metal life under fatigue, so the correction factors for mean stresses developed by Goodman, Morrow, and Smith-Watson-Topper are used to change the power spectral density ...
Social dialogue and the role of the brazilian labour inspection in dealing with the new Coronavirus pandemic
Social dialogue and labour inspection are essential to promote and achieve decent work and are also important in times of crisis. After a brief historical review of social dialogue in Brazil in recent years, the experience of the Brazilian labour inspection in dealing with the crisis caused by the new coronavirus pandemic is described and later compared with the practices adopted by labour inspectorates in other countries. Data collection includes interviews with two social partners and an international survey with the participation of representatives from twelve countries. In the end, guidelines are proposed on how the performance of labour inspection and the use of social dialogue should be in the face of a crisis with negative economic effects in order to overcome it quickly and without major problems, generating beneficial and lasting results in the world of work and helping to recover the economy.
Adoção aberta
Com a perspectiva de proporcionar um processo mais acolhedor para quem está sendo adotado e com maior entendimento por quem pretende adotar, é cabível lançar um exercício hipotético inicial: imagine como seria se existisse um modelo de adoção capaz de conjugar as demandas das família biológica e adotiva e ainda privilegiar o melhor interesse de crianças e adolescentes adotados, permitindo o contato entre todos, mesmo após a conclusão do processo de adoção? Esse caminho pode ser trilhado por meio da adoção aberta – instituto que pressupõe a preservação dos vínculos pré-adoção, por intermédio da instituição de formas de contato entre a família de origem e a famíl...
