This text focuses on the environmental evolution of Mars. Particular emphasis is given to the understanding of Mars as a cold planet throughout its entire geological evolution, starting as a wet world where liquid water was abundant on the surface, albeit the low temperatures, and its sequential transition into a dry planet as temperatures turned even colder.
This book examines five highly influential Francoist films produced from 1938 until 1964 and three later films by critically acclaimed directors Luis BuÃ3Âłuel, Guillermo del Toro, and Alex de la Iglesia that attempt to undermine Francoist aesthetics by re-imagining its visual and narrative cliches.
A Companion to Spanish Cinema is a bold collection of newly commissioned essays written by top international scholars that thoroughly interrogates Spanish cinema from a variety of thematic, theoretical and historic perspectives. Presents an insightful and provocative collection of newly commissioned essays and original research by top international scholars from a variety of theoretical, disciplinary and geographical perspectives Offers a systematic historical, thematic, and theoretical approach to Spanish cinema, unique in the field Combines a thorough and insightful study of a wide spectrum of topics and issues with in-depth textual analysis of specific films Explores Spanish cinema’s cultural, artistic, industrial, theoretical and commercial contexts pre- and post-1975 and the notion of a “national” cinema Canonical directors and stars are examined alongside understudied directors, screenwriters, editors, and secondary actors Presents original research on image and sound; genre; non-fiction film; institutions, audiences and industry; and relations to other media, as well as a theoretically-driven section designed to stimulate innovative research
Seawater: Its Composition, Properties and Behaviour provides a comprehensive introduction to marine science. This book is divided into seven chapters. Chapter 1 summarizes the special properties of water and the role of the oceans in the hydrological cycle. The distribution of temperature and salinity in the oceans and their combined influence on density, stability, and vertical water movements are discussed in Chapters 2 to 4. The fifth chapter describes the behavior of light and sound in seawater and provides examples of the application of acoustics to oceanography. Chapter 6 examines the composition and behavior of the dissolved constituents of seawater, covering minor and trace constituents and major ions, as well as dissolved gases and biologically important nutrients. Residence times, speciation, and carbonate equilibria are also deliberated. The last chapter provides a short review of ideas about the history of seawater, involvement of the oceans in global cycles, and their relationship to climatic change. This publication is beneficial to oceanographers and marine biologists, including students that are interested in marine science.
This book presents recent advances in the field of nanoscale characterization of ferroelectric materials using scanning probe microscopy (SPM). It addresses various imaging mechanisms of ferroelectric domains in SPM, quantitative analysis of the piezoresponse signals as well as basic physics of ferroelectrics at the nanoscale level, such as nanoscale switching, scaling effects, and transport behavior. This state-of-the-art review of theory and experiments on nanoscale polarization phenomena will be a useful reference for advanced readers as well for newcomers and graduate students interested in the SPM techniques. The non-specialists will obtain valuable information about different approaches to electrical characterization by SPM, while researchers in the ferroelectric field will be provided with details of SPM-based measurements of ferroelectrics.
