Download or read book Reactive Extraction written by Hans-Jörg Bart and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This booklet is designed to bridge the gap between handbooks and technical literature and aims at graduate students or experienced readers. Commercial flow sheeting simulation software is increasingly available and is used in the early steps of process design in industry. As to this, more sophisticated and precise models based on activities instead of concentrations should be used. After an introductory chapter there is in Chapter 2 an intensive discussion of reactive phase equilibria of ionic and non-ionic solutes based on chemical potentials. Chapter 3 introduces to multicomponent diffusion and mass transfer. However, the main focus is on the reactive mass transfer on rigid and mobile surfaces where the interfacial reaction, molecular diffusion and adsorption layers are decisive. The respective extraction of zinc with a cation exchanger and of acetic acid with an anion exchanger is discussed as case studies. Since adsorption layers and surfactants have a major impact on liquid-liquid extraction efficiency, the final chapter reviews several tech niques which make use of polymeric species in an extractive process. A short review is also given on extraction apparatus and the hydrodynamics (hydraulic design, droplet populance balances) of columns. Much of the booklet is based on the PhD works of C. Czapla (2000), G. Modes (2000), H. Klocker (1996), T. Kronberger (1995), M. Marters (2000), M. Roos (2000), M. Traving (2000) and B. Wachter (1996) who I wish to thank for their fruitful contributions.

Book excerpt: Mass Spectrometry in Drug Discovery summarizes the theory, instrumentation, techniques, and application of mass spectrometry and atmospheric pressure ionization to screening, evaluating, and improving the performance and quality of drug candidates. It provides time- and cost-efficient approaches for the generation and analysis of effective pharmaceuticals, covers advances in combinatorial chemistry, molecular biology, bioanalysis automation, and computing, and demonstrates the use of mass spectrometry in the assessment of disease states, drug targets, and potential drug agents.

Download or read book Survival of the Prettiest written by Nancy Etcoff and published by Anchor. This book was released on 2011-02-02 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: A provocative and thoroughly researched inquiry into what we find beautiful and why, skewering the myth that the pursuit of beauty is a learned behavior. In Survival of the Prettiest, Nancy Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, argues that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism—it’s in our biology. Beauty, she explains, is an essential and ineradicable part of human nature that is revered and ferociously pursued in nearly every civilization—and for good reason. Those features to which we are most attracted are often signals of fertility and fecundity. When seen in the context of a Darwinian struggle for survival, our sometimes extreme attempts to attain beauty—both to become beautiful ourselves and to acquire an attractive partner—suddenly become much more understandable. Moreover, if we understand how the desire for beauty is innate, then we can begin to work in our own interests, and not just the interests of our genetic tendencies.

Download or read book Port Strategy for Sustainable Development written by Elvira Haezendonck and published by MDPI. This book was released on 2021-03-23 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, most large port hubs include the circular economy transformation challenge, together with smart digitalization and Internet of Things (IoT), in their strategic priorities. However, many ports do not seem to have progressed beyond incremental, small-scale sustainable innovations or the support of rather fragmented sustainability initiatives. The challenges are complex, since ports do not only have to reconsider their own core activities but also their role in the supply chain of shippers, to lift themselves out of the linear lock-in. Opportunities are also created, and port authorities and businesses need to embrace circular learning and turn these projects into sustainable business models. This strategic change or refocus requires new insights into innovative governance and business frameworks, the link between strategy and commercially viable business models, systems innovation, intensified stakeholder collaboration and co-creation, altered traffic segments and hinterland focus, amongst others. These Special Issue articles address current CE transition concerns salient to port strategists and managers, such as first strategic changes towards circular ports, building awareness on the importance of sustainability data and available space, and how port authorities can develop circular business models.

Download or read book Energy Efficiency in Electric Motors Drives Power Converters and Related Systems written by Mario Marchesoni and published by . This book was released on 2020 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, there is a great deal of attention focused on sustainable growth worldwide. The increase in efficiency in the use of energy may even, in this historical moment, bring greater benefit than the use of renewable energies. Electricity appears to be the most sustainable of energies and the most promising hope for a planet capable of growing without compromising its own health and that of its inhabitants. Power electronics and electrical drives are the key technologies that will allow energy savings through the reduction of energy losses in many applications. This Special Issue has collected several scientific contributions related to energy efficiency in electrical equipment. Some articles are dedicated to the use and optimization of permanent magnet motors, which allow obtaining the highest level of efficiency. Most of the contributions describe the energy improvements that can be achieved with power electronics and the use of suitable control techniques. Last but not least, some articles describe interesting solutions for hybrid vehicles, which were created mainly to save energy in the smartest way possible.
