Pollution of water sources with emerging contaminants (micropollutants) is a fact known worldwide. This book examines the presence of micropollutants (medicines, hormones, pesticides) in surface water and the lack of success in removal by conventional water treatment options, then explores nanofiltraion and reverse osmosis methods as better options. The author reviews quantification of removals by means of multivariate data analysis techniques, providing a better understanding of the separation of micropollutants by membranes. He discusses increases in water reuse practices and the important role water membrane treatment will play in the removal of micropollutants and the importance of understanding the characteristics, advantages and disadvantages of nanofiltration and reverse osmosis.
Seawater desalination is increasingly being used as a means to augment freshwater supplies in regions with high water stress, and reverse osmosis is increasingly the technology of choice because of the low energy consumption. However, seawater reverse osmosis (SWRO) systems suffer from various types of fouling, which can increase energy consumption and the use of chemicals during SWRO operation. In practice, pre-treatment systems are put in place to reduce the particulate and biological fouling potential of SWRO feed water. However, simple, reliable and accurate methods to assess the extent to which biological fouling potential is reduced during pre-treatment are not available for seawater. ...
Pollution of water sources with emerging contaminants (micropollutants) is a fact known worldwide. Although the risks of micropollutants in sources of water are partly recognized, interpretation of consequences are controversial; thus, the future effects of altered water with micropollutants remains uncertain and may constitute a point of concern for human beings when potable water consumption is involved. Therefore, many drinking water utilities target as an important goal high-quality drinking water production to lessen quality considerations that may arise from the consumers. In this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.
Lope de Vega's Women and Servants (Mujeres y criados, c. 1613-14), newly translated by Barbara Fuchs, depicts a sophisticated urban culture of self-fashioning and social mobility, as the titular figures outsmart fathers and masters to marry those they love. Recently rediscovered in an overlooked 17th-century manuscript in Madrid's Biblioteca Nacional, the comedia emerges from its 400-year sleep with a remarkable freshness: it presents a world of suave dissimulation and accommodation, where creaky notions of honor and vengeance have virtually no place. Full protagonists of their own stories, women and servants take control of their fates despite their assigned roles in a patriarchal and hiera...
This book emphasizes the significance of affects, feelings and emotions in how we think about politics, gender and sexuality in Latin America. Considering the complex and even contradictory social processes that the region is experiencing today, many Latin American authors are turning to affect to find a key to understand our present situation, to revisit our history, and to imagine new possibilities for the future. This tendency has shown such a specificity and sometimes departure from northern productions that it compels us to focus more deeply on its own arguments, methods, and critical contributions. This volume features essays that explore the particularities of Latin American ways of thinking about affect and how they can shed new light into our understanding of, gender, sexuality and politics.
A comprehensive guide to privileged structures and their application in the discovery of new drugs The use of privileged structures is a viable strategy in the discovery of new medicines at the lead optimization stages of the drug discovery process. Privileged Structures in Drug Discovery offers a comprehensive text that reviews privileged structures from the point of view of medicinal chemistry and contains the synthetic routes to these structures. In this text, the author—a noted expert in the field—includes an historical perspective on the topic, presents a practical compendium to privileged structures, and offers an informed perspective on the future direction for the field. The book...
Citing recently realized applications for extruders as polymerization, modification, and degradation reactors and presenting a telling array of new research results and illustrative experimental cases, Reactive Extrusion Systems sheds light on the complex set of interactions underlying reactions in extruders. The book succeeds as a three-part surve
