Periodic differential equations appear in many contexts such as in the theory of nonlinear oscillators, in celestial mechanics, or in population dynamics with seasonal effects. The most traditional approach to study these equations is based on the introduction of small parameters, but the search of nonlocal results leads to the application of several topological tools. Examples are fixed point theorems, degree theory, or bifurcation theory. These well-known methods are valid for equations of arbitrary dimension and they are mainly employed to prove the existence of periodic solutions. Following the approach initiated by Massera, this book presents some more delicate techniques whose validity is restricted to two dimensions. These typically produce additional dynamical information such as the instability of periodic solutions, the convergence of all solutions to periodic solutions, or connections between the number of harmonic and subharmonic solutions. The qualitative study of periodic planar equations leads naturally to a class of discrete dynamical systems generated by homeomorphisms or embeddings of the plane. To study these maps, Brouwer introduced the notion of a translation arc, somehow mimicking the notion of an orbit in continuous dynamical systems. The study of the properties of these translation arcs is full of intuition and often leads to "non-rigorous proofs". In the book, complete proofs following ideas developed by Brown are presented and the final conclusion is the Arc Translation Lemma, a counterpart of the Poincaré–Bendixson theorem for discrete dynamical systems. Applications to differential equations and discussions on the topology of the plane are the two themes that alternate throughout the five chapters of the book.

Red China prepares to invade Formosa. However, fate intervenes when a pro-democracy Beijing official downloads certain information onto a disk. He then erases the data from their system's mainframe and smuggles the disk out of China. The material must be recovered. Arrangements are made to send a young woman to America with the disk. She barely escapes drowning in the Sea of Cortez. Next she then driven through Mexico and smuggled into El Paso, Texas, there she meets her end. A street youngster sees where she hides the disk before she is murdered, retrieves it and then becomes the object of the hunt. Two Triads, the Mexican mafia and a secret group of right-wing Americans I call the Serpents who then become pitted against one lowly FBI agent; Macias Baca Gonzalez. Special Agent Gonzalez's brother-in-law, an Immigration agent dies in an "accident," his lawyer girlfriend is framed with cocaine and the youngster's mother is murdered all in an effort to deter Agent Gonzalez. Agent Gonzalez finds the youngster, the disk, but then his girl friend Molly is kidnapped for trade. Ultimately a fight ensues and Molly is rescued from an old abandoned brewery. The players and the importance of the information is revealed.
This book describes recent advances in the morphodynamics of mixed sand and gravel Mediterranean coasts, and provides updates and new methods for their study and management. It assesses how the differences in the geomorphic setting, in comparison with traditional sandy beaches, result in distinctive physical processes governing the dynamics of these coasts. Further, on the basis of field measurements, theoretical analysis and numerical modeling carried out at two study sites in southern Spain over the last 15 years, the book studies, analyzes and compares these physical processes and mechanisms. It also shows that the narrow and complex bathymetries and inner shelves modify the wave propagation patterns and hence, the longshore sediment transport gradients along the coast. Given the correlation between the changes in these gradients and the shoreline evolution over time, it identifies the complexity of the inner shelf bathymetries as the main driver of coastal changes and describes these processes in detail using, in the plan view, the inter-annual evolution of unaltered and “altered by human” beaches. Lastly, the book details how the generation and subsequent overlapping of berms across the beach profile are responsible for the sediment variability at depth and cross-shore, and concludes that the total run-up (including the water-level) is a more influential variable than wave height in the erosional/depositional response of these beaches.
This book examines the performance of oscillating water column (OWC) wave energy converters. It discusses the influence of humid air inside the chamber and changes in the seabed, and also investigates the role of wave energy converters in coastal protection. The authors use a real gas model to describe the thermodynamics of the air–water vapour mixture inside the chamber, and the compression and expansion process during the wave cycle. Further, they present an alternative formulation with new perspectives on the adiabatic process of the gaseous phase, including a modified adiabatic index, and subsequent modified thermodynamic state variables such as enthalpy, entropy and specific heat. The book also develops a numerical model using computational fluid dynamics to simulate OWC characteristics in open sea, and studies the performance of a linear turbine using an actuator disk model. It then compares the results from both cases to find an agreement between the analytical and numerical models when humidity is inserted in the gaseous phase. Introducing new concepts to studies of wave energy to provide fresh perspectives on energy extraction and efficiency problems, the book is a valuable resource for researchers and industrial companies involved in thermal energy and coastal engineering. It is also of interest to undergraduate and postgraduate students, as it broadens their view of wave energy.

Islam in Europe' and 'Islamophobia' are subjects of vital global importance which currently preoccupy policy-makers and academics alike. Through the examination of various European Muslim groups and institutions that have branched off from Islamic movements - including the Muslim Brotherhood, Hizb ut-Tahrir and Jama'at-i Islami - this book outlines the configuration of social, political and religious processes that have given rise to new kinds of European Muslim organisations. The authors offer a new perspective on these Muslim groups and seek to reclaim them from the often highly-charged public debates by placing them within the context of their origins as politicised religious movements on the one hand and their ongoing incorporation into European societal structures on the other. They also consider the relationship of these organisations to their 'parent' movements and examine the presence of Islam in European education and higher education institutions. Taking into account the connection between Islamic movements and the perceived surge of 'Islamophobia' in Europe, this book does not debate the question of whether these groups fit into normative or cultural structures of European nation-states, but rather examines how these structures have changed through their interaction with these groups and the growing Muslim population within Europe. It does not consider political Islam as the antithesis to a refined notion of secularism, but as a form of public religion which contributes to the ever-changing structure of Europe's secular regimes. Featuring the work of more than 40 scholars from around the world, this is the comprehensive guide to Islamic movements in Europe, offering original, definitive perspectives on Muslims and Islam in Europe today. It will be essential reading for policy-makers, political commentators and scholars alike.
Aquaculture is the art, science and business of cultivating aquatic animals and plants in fresh or marine waters. It is the extension of fishing, resulted from the fact that harvests of wild sources of fish and other aquatic species cannot keep up with the increased demand of a growing human population. Expansion of aquaculture can result with less care for the environment. The first pre-requisite to sustainable aquaculture is clean wate, but bad management of aquatic species production can alter or even destroy existing wild habitat, increase local pollution levels or negatively impact local species. Aquatic managers are aware of this and together with scientists are looking for modern and more effective solutions to many issues regarding fish farming. This book presents recent research results on the interaction between aquaculture and environment, and includes several case studies all over the world with the aim of improving and performing sustainable aquaculture.
Inflammation of the colon is collectively called "Colitis". Since a variety of conditions may cause colitis and its manifestations are similar among the causes, selection of the right treatment based on the correct diagnosis is important in the management of this group of illnesses. Over the last few decades, a major shift has been observed in the clinical attention to the pathogenesis of colitis from infectious to idiopathic inflammatory bowel diseases. Colitis cases that are associated with chemical therapeutics and specific pathogens such as amoeba, have become prominent in hospitalized individuals and immune deficient patients, respectively. In addition, a great deal of progress has been made in colitis research triggering the need for updating our knowledge about colitis. This book Colitis provides comprehensive information on the pathogenesis, mechanism of resolution, and treatment strategies of colitis.
