The papers in this publication will be talks at the 3 day Gels in Conservation conference held by IAP in association with Tate. The conference will be a gathering of conservators, conservation and other scientists, and students of conservation to present and discuss the theory and practical use of gels in various branches of conservation (paintings, paper, wall paintings, textiles, museum objects etc).The papers and posters present in this publication cover topics on the theory of Gels, recent developments in Gel technologies, clearance and residues, systematic evaluation of Gel properties and effects, preparation and practical issues with case studies concerning: wall paintings, easel paintings, contemporary art, textiles, archaeological objects, paper, sculpture, mixed media, traditional materials and more.
This expansive and practical textbook contains organic chemistry experiments for teaching in the laboratory at the undergraduate level covering a range of functional group transformations and key organic reactions.The editorial team have collected contributions from around the world and standardized them for publication. Each experiment will explore a modern chemistry scenario, such as: sustainable chemistry; application in the pharmaceutical industry; catalysis and material sciences, to name a few. All the experiments will be complemented with a set of questions to challenge the students and a section for the instructors, concerning the results obtained and advice on getting the best outcome from the experiment. A section covering practical aspects with tips and advice for the instructors, together with the results obtained in the laboratory by students, has been compiled for each experiment. Targeted at professors and lecturers in chemistry, this useful text will provide up to date experiments putting the science into context for the students.

A geração de energia proveniente da fonte solar mostrou alto crescimento no Brasil nos últimos anos, sobretudo pela notória queda dos preços da tecnologia solar fotovoltaica. Em menos de uma década, tornou-se uma das fontes renováveis mais competitivas do país, inclusive nos leilões de energia. Além disso, há grande incidência de irradiação solar por todo o território brasileiro, fazendo com que o país tenha alta aptidão para esta fonte. Neste sentido, a energia solar fotovoltaica é um importante vetor para o desenvolvimento sustentável, resultando em geração de empregos e renda, na atração de investimentos e na diversidade e segurança da matriz elétrica nacional. A ...
Phytotherapy Approaches for Treatment of Mouth Ulcers is a book with updated and illustrated text with pictures and graphs that help to define, characterize and classify mouth ulcers. The most frequent oral mucosa lesions are the aphthous ulcerations with a prevalence of 4.6 to 30.6%. These can be defined as a fundamental lesion characterized by the absence of the epithelial tissue layer, which makes the subjacent conjunctive tissue unprotected and vulnerable to external aggressions. There are three main forms, the most common being the aphthous; these are small, rounded, defined ulcerations that are painful and heal in 10 to 14 days. The other form of recurrent aphthous ulceration is the ty...
A novel written as a sharp parable of American society, addressing love, purpose, discrimination, and poverty. In Jeffrey Lewis’s novel, the Land of Cockaigne, once an old medieval peasants’ vision of a sensual paradise on earth, is reimagined as a plot on the coast of Maine. In efforts to assuage their grief over their son’s death and to make meaning of his life, Walter Rath and Catherine Gray build what they hope will be a version of paradise for a group of young men from the Bronx. As Walter and Catherine work to reinvent this land, formerly a summer resort, the surrounding town of Sneeds Harbor proves resistant. The residents’ well-meaning doubts lead to well-hidden threats, and ...
Lasers have become an increasingly useful tool in conventional dental practice. Their precision and less invasive quality make them an attractive technology in esthetic and pediatric dentistry, oral medicine, and a range of other dental procedures. Lasers in Dentistry: Guide for Clinical Practice is a comprehensive, yet concise and easy-to-use guide to integrating lasers into conventional clinical practice. The book begins by providing the reader a thorough understanding of how lasers work and their varied effects on oral tissues. Subsequent chapters are organized by procedure type, illustrating common clinical techniques with step-by-step illustrations and case examples. In addition, each chapter provides an overview of the latest research for use in clinical practice. More comprehensive than at atlas yet practical and clinically oriented in its approach, Lasers in Dentistry is an essential tool for practitioners and students looking to broader their skill set in laser dentistry.
Trillions of commensal microbes reside on and inside the human body, including the intestinal and respiratory tracts, which encompass various microbial taxa, such as bacteria, fungi, archea and viruses. The close proximity of microbes with the host provides an opportunity to continually interact with each other. Advances in research approaches, including high-throughput sequencing, have allowed us to study host and commensal microbes at the genetic and functional levels. Recent studies suggest that commensal microbes play a crucial role in the development of the host’s immune system and induce innate and adaptive immune responses against pathogens. It is also becoming apparent that the gut...
