From Fossils to Astrobiology : Records of Life on Earth and Search for Extraterrestrial Biosignatures
From Fossils to Astrobiology reviews developments in paleontology and geobiology that relate to the rapidly-developing field of Astrobiology, the study of life in the Universe. Many traditional areas of scientific study, including astronomy, chemistry and planetary science, contribute to Astrobiology, but the study of the record of life on planet Earth is critical in guiding investigations in the rest of the cosmos. In this varied book, expert scientists from 15 countries present peer-reviewed, stimulating reviews of paleontological and astrobiological studies. The overviews of established and emerging techniques for studying modern and ancient microorganisms on Earth and beyond, will be valuable guides to evaluating biosignatures which could be found in the extraterrestrial surface or subsurface within the Solar System and beyond.
From Energetics to Ecosystems : the Dynamics and Structure of Ecological Systems
Ecosystems are complex and enigmatic entities that are ultimately our life support systems. Understanding these systems to the point of being able to predict their behaviour in the face of perturbations requires that researchers adopt a number of strategies that vary in both approach and scale. This book, in a sense, is representative of some of the developments that have unfolded when math and physics met ecology. Here, some of the world’s leading ecologists examine ecosystems from theoretical, experimental, and empirical viewpoints, from energetics to ecosystems. The book begins with simplifying and synthesizing nature’s complex relationships. It then moves on to explore the mapping between food web structure and function and ends with the role of theory in integrating different research areas. From the breadth of systems analyzed to the rigor of approaches taken, this book is not only a useful resource for students and researchers in ecology, but also serves as a fitting tribute to the life and work of Peter Yodzis.
From computer literacy to informatics fundamentals ; International conference on informatics in secondary schools : Evolution and perspectives, ISSEP 2005, Klagenfurt, Austria, March 30-April 1, 2005, Proceedings
Duetothepenetrationofinformationtechnologyintosocietyatlargeandinto schools in particular, the relationship between informatics and education leading togeneralcomputerliteracyortotheuseofIT-basedapproachesinconventional subjects, e-learning in school, is an evident focus of many contributions. According to the broad scope of the conference its proceedings are split into two volumes. This volume, From Computer Literacy to Informatics Fundam- tals, covers papers reporting on national strategies of informatics instruction and their evolution in accordance with the penetration of information proce- ing equipment in our daily life. In one way or another, these strategies strive to accommodate the needs of basic skills in information and communication te- nology (ICT) with educational principles that can be conveyed by informatics instruction in a traditional sense. Hence, the papers on national strategies are complementedintwoways: ?rstly, bycontributionsthatstrivetoidentifyfun- mental issues, informatics can contribute to the general education process of the youth; and, secondly, by papers presenting approaches on how to link or even to combine instruction about such informatics fundamentals with the need to introduce pupils to the productive use of ICT.
From Cells to Proteins : Imaging Nature across Dimensions ; Proceedings of the NATO Advanced Study Institute, held in Pisa, Italy, 12-23 September 2004
This book offers updated information on how much information we are able to obtain in the exploration of the inner details of biological specimens in their native structure and composition. And deals with the implementation of laser beam and stage scanning systems incorporating confocal optics or multiphoton microscopy; the advent of new electro-optical detectors with great sensitivity, linearity, and dynamic range; the possibility of 2D fast image enhancement, reconstruction, restoration, analysis and 3D display, and the application of luminescence techniques.
From Bulk to Nano : The Many Sides of Magnetism
The field of magnetism is rapidly advancing in this new millennium, revealing an ever-wider diversity of magnetic phenomena on more than one scale. With the emergence of countless applications particularly on a nanoscale, and their unpredictable implications mostly on a macroscale, it may seem that different aspects of magnetism are unrelated. Quite often, the overwhelming amount of topics discussed in the professional literature views only parts of a field, ignoring a broader context. Therefore, the present book aims at addressing the relationship between apparently unconnected topics in magnetism. Less obvious relationships are revealed among individual fields on various scales, making them better understandable.
From Assessing to Conserving Biodiversity : Conceptual and Practical Challenges
This book despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so? The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that “thing” to which the word ‘biodiversity’ refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous.

Free Energy Calculations : Theory and Applications in Chemistry and Biology
This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles.
Free Energy and Self-Interacting Particles
This book examines a system of parabolic-elliptic partial differential eq- tions proposed in mathematical biology, statistical mechanics, and chemical kinetics. In the context of biology, this system of equations describes the chemotactic feature of cellular slime molds and also the capillary formation of blood vessels in angiogenesis. There are several methods to derive this system. One is the biased random walk of the individual, and another is the reinforced random walk of one particle modelled on the cellular automaton. In the context of statistical mechanics or chemical kinetics, this system of equations describes the motion of a mean field of many particles, interacting under the gravitational inner force or the chemical reaction
Framing in Sustainability Science : Theoretical and Practical Approaches
This book offers both conceptual and empirical descriptions of how to “frame” sustainability challenges. It defines “framing” in the context of sustainability science as the process of identifying subjects, setting boundaries, and defining problems. The chapters are grouped into two sections: a conceptual section and a case section.
Frailty and Kidney Disease : A Practical Guide to Clinical Management
This book is of importance in nephrology, specifically nephrogeriatrics, since frailty is a condition affecting many elderly patients and which is becoming increasingly common in medical practice. As such, there is a considerable need for information to assist professionals treating these patients. The book includes chapters on the frailty syndrome (definition, evaluation and treatment), the main geriatric syndromes (gait disorder, falls, incontinence, and delirium), the main renal syndromes (acute renal injury, chronic kidney disease) as well as dialysis and kidney transplant, and the relationship between geriatrics and renal syndromes.
Fragility fracture nursing : Holistic care and management of the orthogeriatric patient
Aims to provide a comprehensive but practical overview of the knowledge required for the assessment and management of the older adult with or at risk of fragility fracture. It considers this from the perspectives of all of the settings in which this group of patients receive nursing care.
Fractures du genou = Knee fractures
Provides a comprehensive yet practical overview of the management of knee fractures and their complications. The editorial team comprises specialists from France, Switzerland, Belgium, the United States, and Ireland, many of whom are members of the AO group. Imaging strategies, assessment, classification, and anatomical variations are reviewed for each anatomical location. All therapeutic approaches are discussed without exception: conventional implants, intramedullary nailing, minimally invasive techniques, including the role of external fixation, and newer technologies such as the LISS. These approaches are subjected to critical analysis to identify the best options based on the indications and individual circumstances. The patellar apparatus is addressed in its functional unity. Postoperative management, influenced by functional prognosis, is also covered, as is the management of malunion, stiffness, and other complications. Finally, very specific problems are discussed, such as pediatric injuries, patellectomies, periprosthetic fractures, often complex projectile injuries, the role of immediate arthroplasty and massive grafts, but also associated injuries which sometimes have a heavy impact on the final prognosis.
Fracture Mechanics ; Vol.123 : An Introduction
The second edition of the book contains four new chapters in addition to the ten chapters of the first edition. The fourteen chapters of the book cover the basic principles and traditional applications, as well as the latest developments of fracture mechanics as applied to problems of composite materials, thin films, nanoindentation and cementitious materials. Thus the book provides an introductory coverage of the traditional and contemporary applications of fracture mechanics in problems of utmost technological importance.
Fracture Mechanics : With an Introduction to Micromechanics
Concerned with the fundamental concepts and methods of fracture mechanics and micromechanics, Fracture Mechanics primarily focuses on the mechanical description of fracture processes; however, material specific aspects are also discussed. The presentation of continuum mechanical and phenomenological foundations is followed by an introduction into classical failure hypotheses. A major part of the book is devoted to linear elastic and elastic-plastic fracture mechanics. Further subjects are creep fracture, dynamic fracture mechanics, damage mechanics, probabilistic fracture mechanics, failure of thin films and fracture of piezoelectric materials. The book also contains an extensive introduction into micromechanics.
Fractional-in-time semilinear parabolic equations and applications
This book provides a unified analysis and scheme for the existence and uniqueness of strong and mild solutions to certain fractional kinetic equations. This class of equations is characterized by the presence of a nonlinear time-dependent source, generally of arbitrary growth in the unknown function, a time derivative in the sense of Caputo and the presence of a large class of diffusion operators. The global regularity problem is then treated separately and the analysis is extended to some systems of fractional kinetic equations, including prey-predator models of Volterra–Lotka type and chemical reactions models, all of them possibly containing some fractional kinetics.
Fractals in Engineering : New Trends in Theory and Applications
The strong potential of this research can be seen in real industrial situations with recent progress being made in areas such as chemical engineering, internet traffic, physics and finance.
