Multi-phase flows are part of our natural environment such as tornadoes, typhoons, air and water pollution and volcanic activities as well as part of industrial technology such as power plants, combustion engines, propulsion systems, or chemical and biological industry. The industrial use of multi-phase systems requires analytical and numerical strategies for predicting their behavior. In its third extended edition this book contains theory, methods and practical experience for describing complex transient multi-phase processes in arbitrary geometrical configurations. This book provides a systematic presentation of the theory and practice of numerical multi-phase fluid dynamics. In the present second volume the mechanical and thermal interactions in multiphase dynamics are provided. This third edition includes various updates, extensions, improvements and corrections.

This book contains the proceedings of the 12th KES International Conference on Sustainability and Energy in Buildings 2020 (SEB20) held in Split, Croatia, during 24–26 June 2020 organized by KES International.
SEB20 invited contributions on a range of topics related to sustainable buildings and explored innovative themes regarding sustainable energy systems. The aim of the conference is to bring together researchers, and government and industry professionals to discuss the future of energy in buildings, neighbourhoods and cities from a theoretical, practical, implementation and simulation perspective. The conference formed an exciting chance to present, interact and learn about the latest research and practical developments on the subject.

This book presents a comprehensive update on some crucial aspects of brain and spinal tumoral pathology that strongly influence the current surgical management. It covers a range of topics, from the latest results of molecular diagnosis for tumors still considered unsuitable for surgical excision, to the increasing use of minimally invasive approaches made possible by the wide application of neuroendoscopic techniques.

This comprehensive book, divided into seven sections, showcases groundbreaking research findings that blend new experiences from the COVID-19 pandemic with long-term research on online laboratories and virtual experimentation. Providing an adequate learning experience in the laboratory has long been a major challenge in science, engineering, and technology education. Recent years have further revealed the complexities of offering distance or remotely accessible educational settings, particularly for laboratory-based courses. In response, many academic institutions have innovated by transitioning their laboratory classes into online laboratories or providing laboratory kits for at-home use. This unprecedented situation has sparked numerous new developments, approaches, and activities, revolutionizing the field.

The rapid growth of gemological sciences and mineralogy requires a comprehensive dictionary for gemologists, mineralogists, geologists, jewel dealers, industry, and hobbyists. The third edition of this dictionary contains about 24,000 entries – about 4,000 more than the second edition. The comprehensive definitions are now completed by more than 1,500 charts, diagrams and figures. The author offers a one-stop reference to any matter dealing with gems and gemology.

Although Leonardo’s Giant Crossbow is one of his most popular drawings, it has been one of the least understood. "Leonardo’s Giant Crossbow" offers the first in-depth account of this drawing’s likely purpose and its highly resolved design. This fascinating book has a wealth of technical information about the Giant Crossbow drawing, as it’s a complete study of this project, though this is as accessible to the general audience as much as it is also informative with new discoveries for the professors of engineering, technology and art. The book explores the context of Leonardo’s invention with an examination of the extensive documentary evidence, a short history of the great crossbow and ballista, the first accurate translation of the text and the technical specifications, and a detailed analysis of Leonardo’s design process for the crossbow, from start to finish. Dozens of preparatory drawings, along with the recent discovery of nearly invisible metal stylus preparatory incisions under the ink of the Giant Crossbow drawing, are evidence of Leonardo’s intent to offer engineers and other viewers a thorough design of the massive machine. The book proposes these new discoveries with the help of a strategy that had been at the core of Leonardo’s working philosophy: the proportional method. As proven with an analysis of the Giant Crossbow project, he used a consistent approach to 1/3rd proportions throughout the design and drawing process and employed this kind of proportional strategy at the start of almost every important project. Thanks to this proof of his knowledge of geometry, evidence of his studies of impetus and force, and thanks to the highly polished and complex nature of the Giant Crossbow design, a later date for the drawing is proposed in the present book, associating the drawing with his drafting capabilities around 1490-93.

Michael Wolffsohn setzt sich, ausgehend von der aktuellen Politik, in seinem neuen Buch mit dem Verhältnis  von Judentum, Christentum und Islam – gestern, heute und morgen – auseinander. In gewohnt pointierter Weise zieht er dazu Geschichte und Theologie heran. Seine illusionslosen und dennoch teils humorvollen und immer messerscharfen Analysen gelten insbesondere Terror, Krieg und Gewalt. Seine große mediale Präsenz als Talkshowgast, Interviewpartner und Publizist erklärt sich durch seine Fähigkeit zu faktengesättigten und allgemeinverständlichen Statements, die auch dieses Buch prägen. Vor dem Hintergrund eines wachsenden Antisemitismus in Europa, einer Zunahme des islamistischen Terrors und des eskalierenden Krieges zwischen Israel und seinen Nachbarn sind Michael Wolffsohns grundsätzliche Einordnungen und Erklärungen zum besseren Verständnis unabdingbar.

Was man wirklich über Klima-Kipppunkte wissen muss
Überschwemmungen, Hitzewellen, Dürren, Waldbrände - die Auswirkungen des immer extremeren Wetters sind auch hierzulande zunehmend spürbar. Aber all das ist erst der Anfang: Weil das 1,5-Grad-Limit nicht mehr zu halten ist und die Erderhitzung fortschreitet, drohen in naher Zukunft im Klimasystem mehrere sogenannte Kipppunkte überschritten zu werden. Die Folgen wären einschneidend, auch für Deutschland.
