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.
The principles of christian education and the confessional schools lutheran administration in the context of the pedagogic ideas in the south of Brazil
This work is developed from studies about the principles of the Christian Lutheran education and the administration of confessional schools in the context of the pedagogic ideas in the south of Brazil (1824-1997). This subject is of general interest, as it can be verified by the selection of articles published in the magazines of the Lutheran Churches in Brazil. This administration encompasses the director, the professor, and the parents, so that they may work together in search for a clear view of the mission, that is, the meaning of the existence of a confessional school. The aims of this research is to clarify questions in the History of Education, as well as in the administration of priv...
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.
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.
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 ...
The End of Democracy
Gilberto Lopes, with this profound and provocative study based on an ingenious imaginary dialogue between Alexis de Tocqueville (1805-1859) and Karl Marx (1818-1883) on democracy, presents us with a disturbing work on one of the most important debates in today's political world. This work arises from a practical concern, from a life experience and a political restlessness, but also from a theoretical curiosity to make a journey inspired by the work of these two great thinkers who approached the history of their time with particular acuity and erudition. The relevance of the approaches presented here is evident as we face, day by day, the challenges that the "democracy" of today's world must confront: growing inequality, greater concentration of wealth, absurd wars and ever deeper and more widespread environmental deterioration. Faced with the state of political and economic confusion that reigns everywhere, Gilberto Lopes proposes, in a renewed and necessary debate on democracy and socialism, to glimpse the signs of progress on the road to equality suggested by Tocqueville as the great engine of history. This book aims to help us successfully reach the end of that road.
