O objetivo de Reflexões contemporâneas é apresentar uma obra que seja fruto do protagonismo discente em seu processo formativo e uma aplicação de conteúdos escolares para a leitura e posicionamento do/no mundo: objetivo central da formação linguística crítica.
With substantial contributions from experienced industrial scientists and engineers, this work will have real application towards improving process efficiency and improvement in the trillion-dollar global petroleum industry. It presents an overview of the emerging field of petroleomics, which endeavors to understand the fundamental components of crude oil. Petroleomics promises to revolutionize petroleum science in much the same way that genomics transformed the study of medicine not long ago. Asphaltenes are a particular focus, with many chapters devoted to the analysis of their structure and properties.
This thesis addresses the evolving field of measurement science, specifically that of mass spectrometry (MS) and ion mobility spectrometry (IMS) based techniques. It focuses on the design, construction and implementation of low-cost, easy-to-manufacture measurement tools that are used in modern settings such as airport security screening. Advances in these technologies often involve minimal performance enhancement at ever-increasing cost, which in turn limits accessibility to versatile measurement tools. This problem is addressed using desktop 3D printers along with widely available materials for the production of novel ion lenses and an IMS instrument with a performance comparable to that of many commercial systems. Baird ́s findings are a source of inspiration for scientists exploring this emerging field./div
The most comprehensive and up-to-date volume on environmental analysis available today, this is the standard laboratory reference for any environmental or chemical engineer, chemist, or scientist. Today, environmental issues are a great cause of concern at the global level, and universities and other institutions around the world are involved in research on climate change, deforestation, pollution control, and many other issues. Moreover, environmental science and environmental biotechnology are inherent parts of various courses while some universities provide degrees in these fields. Although the environment perspective of water is discussed time and again in research, academic, and non-aca...
Oxides and acids of nitrogen play an important role in regulating atmospheric radical levels, in particular, that of the OH radical the main initiator of the degradation of chemicals in the atmosphere. A comprehensive overview on the methods used to measure nitrogen oxides and acids in the troposphere is given and difficulties and artefacts associated with the use of the techniques for measurements in urban and mega city environments is illustrated. State-of-the-art methods for the measurement of OH and HO2 radicals are reviewed and recently recognised difficulties, in particular with the measurement of HO2 radicals, are highlighted. Other contributions to the book cover our present understa...
The Holy Spirit continues to be at work around the world, yet much confusion and controversy remain regarding the Holy Spirit's activity. In this classic study, John Stott provides clear biblical exposition on the promise, the fruit, and the gifts of the Holy Spirit, expanding on the nature of "the baptism of the Spirit" and whether certain spiritual experiences should be normative for all Christians.
"Cutting, burning, branding, and bone-breaking are all types of self-injury, of the deliberate, non-suicidal destruction of one's own body tissue, a practice that emerged from obscurity in the 1990s and spread dramatically as a typical behavior among adolescents. Long considered a suicidal gesture, The Tender Cut argues instead that self-injury is often a coping mechanism, a form of teenage angst, and expression of group membership, and a type of rebellion, converting unbearable emotional pain into manageable physical pain. An important portrait of a troubling behavior, The Tender Cut illuminates the meaning of self-injury in the 21st century, its effects on current and former users, and its future as a practice for self-discovery or a cry for help."--P. [4] of cover.
This commentary, a part of the Old Testament Library Series, focuses on the book of Psalms. The Old Testament Library provides fresh and authoritative treatments of important aspects of Old Testament study through commentaries and general surveys. The contributors are scholars of international standing.
The photophysical and photochemical properties of probes in biological and in model systems are topics of intense current research. The wavelength, intensity, time and polarisation dependence of fluorescence probes can provide information on properties as diverse as electric fields and changes in conformation and may be used in the formidable task of establishing structure-function relationships in proteins and cell membranes. The wide scope of interactions which can be studied by these fluorescent molecules is illustrated in the articles in this volume which are based on talks, although much extended and updated, given at a meeting on 'Fluorescence Probes in Proteins and Membranes' held in the Royal Institution in November 1979.
