This book provides an overview of solar wind turbulence from both the theoretical and observational perspective. It argues that the interplanetary medium offers the best opportunity to directly study turbulent fluctuations in collisionless plasmas. In fact, during expansion, the solar wind evolves towards a state characterized by large-amplitude fluctuations in all observed parameters, which resembles, at least at large scales, the well-known hydrodynamic turbulence. This text starts with historical references to past observations and experiments on turbulent flows. It then introduces the Navier-Stokes equations for a magnetized plasma whose low-frequency turbulence evolution is described within the framework of the MHD approximation. It also considers the scaling of plasma and magnetic field fluctuations and the study of nonlinear energy cascades within the same framework. It reports observations of turbulence in the ecliptic and at high latitude, treating Alfvénic and compressive fluctuations separately in order to explain the transport of mass, momentum and energy during the expansion. Further, existing models are compared with direct observations in the heliosphere. The problem of self-similar and anomalous fluctuations in the solar wind is then addressed using tools provided by dynamical system theory and discussed on the basis of available models and observations. The book highlights observations of Yaglom’s law in solar wind turbulence, which is one of the most important findings in fully developed turbulence and directly related to the long-lasting and still unsolved problem of solar wind plasma heating. Lastly, it includes a short chapter dedicated to the kinetic range of fluctuations, which has recently been receiving more attention from the space plasma community, since this is inherently related to turbulent energy dissipation and consequent plasma heating. It particularly focuses on the nature and role of the fluctuations populating this frequency range, and discusses several model predictions and recent observational findings in this context.
Industrial mathematics is evolving into an important branch of mathematics. Mathematicians, in particular in Italy, are becoming increasingly aware of this new trend and are engaged in bridging the gap between highly specialized mathematical research and the emerging demand for innovation from industry. The contributions in this volume provide both R&D workers in industry with a general view of existing skills, and academics with state-of-the-art applications of mathematics to real-world problems, which may also be incorporated in advanced courses.
This book provides a compact history of gears, by summarizing the main stages of their development and the corresponding gradual acquisition of engineering expertise, from the antiquity to the Renaissance and the twentieth century. This brief history makes no claim to be exhaustive, since the topic is so extensive, complex and fascinating that it deserves an entire encyclopedia. Despite its brevity, the book debunks a number of popular misconceptions, such as the belief that the first literary description of a gear was supplied by Aristotle. It disproves not only this myth, but also other peremptory statements and/or axiomatic assumptions that have no basis in written documents, archaeological findings or other factual evidence. The book is chiefly intended for students and lecturers, historians of science and scientists, and all those who want to learn about the genesis and evolution of this topic.

Vincenzo Consolo is counted by many critics among the most significant voices in contemporary world literature. This volume makes available for the first in English an edited and annotated volume of Consolo's short stories, essays, and other writings pertaining to the diverse cultures and histories of Sicily and the Mediterranean basin. The Mediterranean region holds a particular fascination for Consolo, who seeks through his writing to recover the memory of a Sicilian and Mediterranean history, which he feels is presently being threatened by the forces of late-capitalist Western culture. His writings about the region also voice a commitment to questions of ethics and human rights, which have been brought to the fore by recent tensions dividing this area and forcing a mass exodus of its people. At a time when this part of the world is under threat from unbridled globalization as well as dangerous forms of ethnic and religious fundamentalism, Consolo's words offer an insightful rethinking of regionalism within a global hierarchy of values. They remind us of the necessity of moderation and contingency, and in so doing, attempt to recover a moral and ethical dimension for our collective life.
This book is in part autobiographical in that it examines the life of Vincenzo Rulli. It is a story that needs telling. It needs telling because his life commences with an awareness of him being disassociated from his body. It needs telling because it traces the struggles of his parents and the history behind their decision to leave their country of birth and migrate to Australia in search of a better life. It is a story that needs telling because it chronicles the happy years when the family lived, worked together, children married and grandchildren and parents visited grandparents on a weekly basis, and grandchildren played together. It needs telling because it is filled with paranormal phenomena that followed Vincenzo from birth to the murder of one of his nieces and beyond. It needs telling because it chronicles thirty-four years of struggles by Vincenzo and the police of the state of NSW who having arrested charged and convicted one person, rested on their laurels, notwithstanding evidence within their own brief that points to the complicity of others, it needs telling because Vincenzo gathered evidence that should have been gathered by police and that even though this evidence supports the hypothesis that more than one person was involved, the police could not be moved from their position that only one person was involved in the murder of his niece. It needs telling because this story is proof positive for the proposition that good guys don’t always win, and yes you can get away with murder.
The book presents topics in discrete biomathematics. Mathematics has been widely used in modeling biological phenomena. However, the molecular and discrete nature of basic life processes suggests that their logic follow principles that are intrinsically based on discrete and informational mechanisms. The ultimate reason of polymers, as key element of life, is directly based on the computational power of strings, and the intrinsic necessity of metabolism is related to the mathematical notion of multiset. The switch of the two roots of bioinformatics suggests a change of perspective. In bioinformatics, the biologists ask computer scientists to assist them in processing biological data. Conversely, in infobiotics mathematicians and computer scientists investigate principles and theories yielding new interpretation keys of biological phenomena. Life is too important to be investigated by biologists alone, and though computers are essential to process data from biological laboratories, many fundamental questions about life can be appropriately answered by a perspicacious intervention of mathematicians, computer scientists, and physicists, who will complement the work of chemists, biochemists, biologists, and medical investigators. The volume is organized in seven chapters. The first part is devoted to research topics (Discrete information and life, Strings and genomes, Algorithms and Biorhythms, Life Strategies), the second one to mathematical backgrounds (Numbers and Measures, Languages and Grammars, Combinations and Chances).

Le letture di Nietzsche sono farmaci per il mal di vivere. Nietzsche è una risorsa fondamentale per mettere in atto tutta la forza che spesso non siamo in grado di percepire per fronteggiare gli imprevisti che la vita ci riserva. E così i nostri stati d'animo si appesantiscono sempre di più e nessuno di essi assomiglia con precisione a un altro, bensì ciascuno è infinitamente giovane, come se fosse il Parto dell'Attimo, ed esso vuole espandersi sempre più in alto, sempre più in profondo. A volte siamo così deboli che crediamo tutto il nostro passato sia una fardello da cui è impossibile liberarci. V.ISAIA
La depurazione delle acque reflue rappresenta una delle principali esigenze per la tutela delle risorse idriche, dell'ambiente e della salute dell'uomo. L'attenzione del legislatore, del mondo tecnico e delle imprese è sempre più rivolta alle possibilità di recupero e riutilizzo delle acque depurate con soluzioni e tecnologie sostenibili e tali da garantire l'assenza di rischi. I bioreattori a membrane (MBR) rappresentano l'evoluzione dei trattamenti biologici convenzionali, sono proposti come soluzione tecnologica del futuro e consentono il raggiungimento di elevati rendimenti depurativi e la possibilità di riutilizzo delle acque trattate. L'utilizzo di tecnologie avanzate richiede, però, opportuna competenza in fase di progettazione e di gestione e necessità di attenzione specifica.
Questo non è un libro sui tanti (o pochi) amici e parenti che regolarmente "vegetano" nel vostro salotto, ma proprio il manuale di un rivoluzionario sistema di coltivazione che vi permetterà di avere sempre a portata di mano, anche dentro casa, erbe aromatiche ed ortaggi coltivati senza terra. Perché se - come ha detto qualcuno - la cultura (quella con la "u") non si mangia, le "colture" invece, sì!
