Formulações saneantes, geis, aromatizantes de ambiente, repelentes naturais e sabonetes alternativos
A Fábrica Escola de Detergentes é um projeto de extensão do Instituto Federal do Paraná (IFPR) Campus Palmas que desenvolve estudos, pesquisas e ações extensionistas para produção de saneantes. As atividades realizadas nesse espaço formativo relacionam questões ambientais, tecnológicas e sociais com fundamento da formação integral e, portanto, científica, cidadã e social. Ainda, por meio da articulação entre a teoria e prática formativas, há o envolvimento da comunidade interna e externa. Durante as atividades realizadas no projeto de extensão, busca-se aproximar as demandas e conhecimentos populares aos conceitos, práticos e teorias científicas, como forma de qualificar e referenciar socialmente as ações do projeto. Por exemplo, o termo científico tensoativo é bastante utilizado durante as atividades, sendo pouco conhecido e/ou usado na linguagem popular. Os tensoativos são as substâncias que conferem a função de limpeza aos produtos e, portanto, interferem em seu rendimento e no preço de venda.
EBOOK: Meaning Making in Secondary Science Classroomsaa
This book focuses on the talk of science classrooms and in particular on the ways in which the different kinds of interactions between teachers and students contribute to meaning making and learning. Central to the text is a new analytical framework for characterising the key features of the talk of school science classrooms. This framework is based on sociocultural principles and links the work of theorists such as Vygotsky and Bakhtin to the day-to-day interactions of contemporary science classrooms. *presents a framework, based on sociocultural theory, for analysing the language of teaching and learning interactions in science classrooms *provides detailed examples and illustrations of in...
Green Chemistry Education
Green Chemistry has brought about dramatic changes in the teaching of chemistry that have resulted in increased student excitement for the subject of chemistry, new lecture materials, new laboratory experiments, and a world-wide community of Green Chemistry teachers. This book features the cutting edge of this advance in the teaching of chemistry.
Sensory Evaluation Practices
Sensory Evaluation Practices examines the principles and practices of sensory evaluation. It describes methods and procedures for the analysis of results from sensory tests; explains the reasons for selecting a particular procedure or test method; and discusses the organization and operation of a testing program, the design of a test facility, and the interpretation of results. Comprised of three parts encompassing nine chapters, this volume begins with an overview of sensory evaluation: what it does; how, where, and for whom; and its origin in physiology and psychology. It then discusses measurement, psychological errors in testing, statistics, test strategy, and experimental design. The re...
Bioactive Compounds from Natural Sources, Second Edition
The first edition of Bioactive Compounds from Natural Sources was published in a period of renewed attention to biologically active compounds of natural origin. This trend has continued and intensified—natural products are again under the spotlight, in particular for their possible pharmacological applications. Largely focusing on natural products as lead compounds in drug discovery, Bioactive Compounds from Natural Sources, Second Edition: Natural Products as Lead Compounds in Drug Discovery is actually a completely new volume containing surveys of selected recent advances in an interdisciplinary area covering chemistry of natural products, medicinal chemistry, biochemistry, and other rel...
Chemical Technology in Antiquity
Chemistry is intimately involved in the development of the oldest known civilizations, resulting in a range of chemical technologies that not only continue to be part of modern civilized societies, but are so commonplace that it would be hard to imagine life without them. Such chemical technology has a very long and rich history, in some cases dating back to as early as 20,000 BCE. "Chemistry Technology in Antiquity" aims to present the discovery, development, and early history of a range of such chemical technologies, with the added goal of including a number of smaller subjects often ignored in the presentation of early chemical technology. While the book does not aim to be a comprehensive coverage of the full range of chemical technologies practiced during antiquity, it provides a feel and appreciation for both the deep history involved with these topics, as well as the complexity of the chemical processes that were being utilized at such a very early time period.
Cinnamon and Cassia
Cinnamon and Cassia, the "Spices of Life", together constitute one of the most widely used group of spices. A comprehensive volume, Cinnamon and Cassia: Genus Cinnamomum explores in detail Srilankan cinnamon, Chinese cassia, Indonesian cassia, Indian cassia, camphor, and also the important related and useful spices of Cinnamomum. The introdu
Identification of Essential Oils by Ion trap Mass Spectroscopy
This handbook presents the ion trap mass spectra of the most common terpenes (hydrocarbons found in oils, resins, and balsams) found in nature, including relative retention/elution times, an extensive synonymy of common and IUPAC names, CAS registry numbers, molecular formulas, and structures. Includes 502 spectra of essential oils from predominantly plant sources Presents an overview of the ion trap system
