    Description / Table of Contents: This book illustrates the diversity of hypogene speleogenetic processes and void-conduit patterns depending on variations of the geological environments by presenting regional and cave-specific case studies. The cases include both well-known and newly recognized hypogene karst regions and caves of the world. They all focus on geological, hydrogeological, geodynamical and evolutionary contexts of hypogene speleogenesis. The last decade has witnessed the boost in recognition of the possibility, global occurrence, and practical importance of hypogene karstification (speleogenesis), i.e. the development of solutional porosity and permeability by upwelling flow, independent of recharge from the overlying or immediately adjacent surface. Hypogene karst has been identified and documented in many regions where it was previously overlooked or misinterpreted. The book enriches the basis for generalization and categorization of hypogene karst and thus improves our ability to adequately model hypogene karstification and predict related porosity and permeability. It is a book which benefits every researcher, student, and practitioner dealing with karst

    Description / Table of Contents: The book encompasses a set of papers on meteorological tsunamis covering various aspects on this rare but potentially destructive multiresonant phenomenon. Altogether an editorial and 15 contributions are part of this book; eight of the contributions deal with different aspects of meteotsunamis along the U.S. East Coast and in the region of the Great Lakes, including one paper introducing a new methodology in meteotsunami research. Seven more papers are documenting meteotsunamis in various coastal areas of the world oceans. All continents, except Antarctica, have been covered, with the authors representing 11 countries.

    Description / Table of Contents: Tsunami science has evolved significantly since the occurrence of two of the most destructive natural disasters in recent times: the 26 December 2004 Sumatra tsunami that killed about 230,000 people along the coasts of 14 countries in the Indian Ocean and the 11 March 2011 Tohoku (Great East Japan) tsunami that killed almost 20,000 people and destroyed the Fukushima Daiichi nuclear power plant. As a result of these and many other destructive tsunamis that have occurred over just the last decade, scientists from around the world have come together to engage in tsunami research. The global community of researchers has also expanded by discipline, adapting advances in other sciences to study all aspects of tsunami hydrodynamics, detection, generation, and probability of occurrence. The papers presented in this first of two topical volumes of Pure and Applied Geophysics reflect the state of tsunami science during this time. Nine papers examine various aspects of tsunami hazard and risk assessment. Five papers present new methods for tsunami warning and detection and six other papers describe new methods for understanding tsunami hydrodynamics. The final five papers of the volume describe tsunamis generated by non-seismic sources and important case studies. Collectively, this volume highlights contemporary trends in global tsunami science, both fundamental and applied toward hazard assessment and mitigation. The volume is of interest to scientists and practitioners involved in all aspects of tsunamis from source processes to coastal impacts. Postgraduate students in geophysics, oceanography and coastal engineering - as well as students in the broader geosciences, civil and environmental engineering - will also find the book to be a valuable resource, as it combines recent case studies with advances in tsunami science and natural hazards mitigation

    Description / Table of Contents: This volume presents a collection of contributions that were published in "Pure and Applied Geophysics - pageoph" and which deals with the major earthquake that hit Illapel, Chile on September 16, 2015 with magnitude 8.3, and associated trans-oceanic tsunami. The subducting Nazca plate beneath the Andes caused this major earthquake, generating strong shaking, permanent deformation, free oscillations of the Earth, and tsunamis. This event occurred in the flat-angle subducting segment of the plate.The generated tsunami spread throughout the entire Pacific Ocean and was recorded by numerous coastal tide gauges and open-ocean DART stations. All articles give an up-to-date account of research in one of the most active seismic zones worldwide. An introductory article by Kenji Satake rounds this collection off

    Notes: Interpolymer reactions between poly(acrylic acid) (PAA) or poly(methacrylic acid) (PMAA) and poly(N-tert-butylaziridine) (PTBA) were studied and compared with the corresponding reactions of these polyacids with linear polyethyleneimine (LPEI). In aqueous alkaline and salt media the presence of the bulky non-polar N-substituent in the main chain of PTBA results in a decrease of stability of polyacid-PTBA polyelectrolyte complexes. LPEI, which forms stronger salt bonds with PAA, substitutes PTBA in the PAA-PTBA polyelectrolyte complexes. Addition of simple salts to aqueous solutions of non-stoichiometric polyelectrolyte complexes (N-PEC) PAA-PTBA and PMAA-PTBA at room temperature causes a phase separation due to macromolecular exchange and disproportionation reactions. At elevated temperatures (T = 40 - 60 °C), however, the macromolecular exchange between different N-PEC particles does not occur and phase separation in aqueous salt solution of the N-PEC's PAA-PTBA, PMAA-PTBA is not observed. This is attributed to hydrophobic interactions in polyacid-PTBA complexes due to the presence of the tert-butyl groups in the latter.

    Notes: The interaction between oppositely charged linear and crosslinked polyelectrolytes and the molecular mechanism of the transport of linear polyelectrolytes into oppositely charged gels were studied. The mechanism represents a “relay-race” transfer of polyion segments from one fragment of the polyelectrolyte network to the other via interpolyelectrolyte exchange reaction. Thus, the whole layer of the formed interpolyelectrolyte complex serves as an active zone. The driving force for the transport is produced by interpolyelectrolyte addition reaction on the solution/gel interface.

    Notes: The competitive binding of fluorescence-tagged poly(methacrylate) polyanions and poly(phosphate) polyanions with different poly(N-alkyl-4-vinylpyridinium) polycation quenchers (alkyl = methyl, ethyl and propyl) was studied in the region 278÷333 K by fluorescence quenching technique. The equilibrium of this interpolyelectrolyte substitution reaction proved to be temperature sensitive except in the case when the poly(N-methyl-4-vinylpyridinium) polycation was used. Thermodynamic parameters of the reaction were determined. The possibility of effective temperature control of the interpolyelectrolyte reaction might be important for understanding, prediction and utilization of transformation processes of complex particles formed by electrostatically complementary (biological) macromolecules.

    Notes: The biocompatibility and high gas transfer characteristics of gas-permeable membranes have led to their use for total and supportive cardiopulmonary bypass. The gas transfer rates, particularly of oxygen, have previously been measured with sophisticated apparatus and this has restricted accurate measurements to a few laboratories. A simple chemical technique for measuring the oxygen permeability of synthetic membranes is described, in which sodium hydrosulfite is used to provide the highest possible oxygen gradient and the volume of oxygen crossing the membrane is measured volumetrically. Results agreed with those obtained with orthodox apparatus and replacement of the reducing agent with blood gave much lower oxygen transfer rates demonstrating the rheological influences of the blood upon oxygen transfer.
