This new, revised and updated edition takes into account the most recent advances in the understanding of human pathophysiology. The book presents the complex basic principles of vascular hemodynamics and its pathophysiologie in a direct and effective way, stressing the importance of the mechanical properties of large arteries in the origin of blood pressure. The readily understandable text, supported by helpful images, describes the elements that define blood pressure and explains such important concepts as pulse wave velocity, central blood pressure, reflected waves, and pulse pressure amplification. Entirely new chapters are included on the sympathetic nervous system and arterial stiffness and on the role played by arterial stiffness in influencing blood pressure variability. The book will enable the physician to answer some of the key questions encountered when addressing the problem of arterial hypertension in everyday clinical practice: How is blood pressure generated? How should blood pressure values be interpreted? Is systolic blood pressure of greater importance than diastolic blood pressure?

Hydrodynamics of Time-Periodic Groundwater Flow...
146,99 € *
ggf. zzgl. Versand

Hydrodynamics of Time-Periodic Groundwater Flow introduces the emerging topic of periodic fluctuations in groundwater. While classical hydrology has often focused on steady flow conditions, many systems display periodic behavior due to tidal, seasonal, annual, and human influences. Describing and quantifying subsurface hydraulic responses to these influences may be challenging to those who are unfamiliar with periodically forced groundwater systems. The goal of this volume is to present a clear and accessible mathematical introduction to the basic and advanced theory of time-periodic groundwater flow, which is essential for developing a comprehensive knowledge of groundwater hydraulics and groundwater hydrology. Volume highlights include: Overview of time-periodic forcing of groundwater systems Definition of the Boundary Value Problem for harmonic systems in space and time Examples of 1-, 2-, and 3-dimensional flow in various media Attenuation, delay, and gradients, stationary points and flow stagnation Wave propagation and energy transport Hydrodynamics of Time-Periodic Groundwater Flow presents numerous examples and exercises to reinforce the essential elements of the theoretical development, and thus is eminently well suited for self-directed study by undergraduate and graduate students. This volume will be a valuable resource for professionals in Earth and environmental sciences who develop groundwater models., including in the fields of groundwater hydrology, soil physics, hydrogeology, geoscience, geophysics, and geochemistry. Time-periodic phenomena are also encountered in fields other than groundwater flow, such as electronics, heat transport, and chemical diffusion. Thus, students and professionals in the field of chemistry, electronic engineering, and physics will also find this book useful.

Between Globalization and Integration - The Eur...
51,16 € *
ggf. zzgl. Versand

This volume focuses on the integration and globalization of Romania, a prominent emerging market in South-Eastern Europe and one of the major players in the securitization of the Black Sea and the Eastern European border, as both a part of NATO since 2004 and a fully integrated EU Member State since 2007. It will examine the challenges the country has faced in its progression from totalitarianism to democracy through several waves of reform intended to update and streamline its political and economic processes for success in the free-market capitalist arena. Having learned the hard way about some of the key aspects of public administration, Romania has learned a place for itself among the diverse global players of Europe and beyond. The first section reviews current perspectives on globalization and its impact in the late 20th century. It has flattened the Earth, generating better communication and exchanges than ever before, but also gathering a fair amount of criticisms from commentators seeing it as little else than neo-colonialism. Cooperative-administrative strategies are being suggested instead, in order for new public administration patterns to smoothly run in coordination with the globalized world. In the second section, the European Union is described as a complex multi-level socio-political entity, itself historically in turmoil over its own style of rule - e.g. hierarchy vs. coordination, integration vs. centralization, etc. - or even its own existence, as the European dream seemed to be losing steam with the general population of Europe several times in the previous century. Powers and responsibilities of the European institutions and agencies are also discussed. Thirdly, the recent history of Romania is approached from the Europeanization context, starting from its post-1989 days of confusion and of attempting to jumpstart democracy. Eventually, it has to undergo a series of reforms and internalize some principles fundamental to the EU in order for the much-awaited accession to occur and its multiple effects to start taking place. A country with a rich cultural heritage and straddling multiple socio-political axes, Romania has plenty more to offer in the new geostrategic, security and development contexts of the 21st-century Europe. As such, this volume provides inspiration for further research and practical application opportunities on topics of local, European and global significance. Dr. Sebastian A. V?duva is the current Dean of the Griffiths School of Management at the Emanuel University in Oradea, Romania, as well as a management scholar with numerous active ties, academic and entrepreneurial, in both Europe and the United States. He has developed various seminars on leadership and effective management on both micro- and macro-economic levels and is behind several programs intended to boost Romanian economy by drawing in international investors and business partners.

This thesis focuses on magnetic reconnection processes in the boundary layer of the interplanetary magnetic cloud. Magnetic reconnection is an important and frontier topic in the realm of physics. Various physical phenomena can be observed during the reconnection process but lots of them are not fully understood. This thesis provides the first observational evidence of energetic electrons associated with magnetic reconnection in the solar wind and discusses the particle acceleration problems. In addition, after analyzing the particle flux variations in Magnetic Cloud Boundary Layer, the thesis proposes a possible new criterion for the identification of magnetic reconnection in the solar wind. These tantalizing results could be particular clues to understand the dynamical problems in magnetic reconnection processes.
