Mechanism, Life and Mind in Modern Natural Philosophy (International Archives of the History of Ideas Archives internationales d'histoire des idées #240)

by Charles T. Wolfe Paolo Pecere Antonio Clericuzio

This volume emphasizes the diversity and fruitfulness of early modern mechanism as a program, as a concept, as a model. Mechanistic study of the living body but also of the mind and mental processes are examined in careful historical focus, dealing with figures ranging from the first-rank (Bacon, Descartes, Spinoza, Cudworth, Gassendi, Locke, Leibniz, Kant) to less well-known individuals (Scaliger, Martini) or prominent natural philosophers who have been neglected in recent years (Willis, Steno, etc.). The volume moves from early modern medicine and physiology to late Enlightenment and even early 19th-century psychology, always maintaining a conceptual focus. It is a contribution to a newly active field in the history and philosophy of early modern life science. It is of interest to scholars studying the history of medicine and the development of mechanistic theories.

Mechanism of Functional Expression of F1-ATPase (SpringerBriefs in Molecular Science)

by Masahiro Kinoshita

This book presents a new view of the mechanism of functional expression of ATP-driven motors (proteins or protein complexes). It is substantially different from the prevailing idea that the motor converts chemical energy to mechanical work. To facilitate understanding, the differences between the new and prevailing views are explained using many illustrations. The book is of interest to those who are not convinced of the notion of chemo–mechanical coupling. The claims presented are the following: The system, which comprises not only the motor but also water, does no mechanical work during the ATP hydrolysis cycle; a protein is moved or a protein in the complex is rotated by the entropic force generated by water. The highlight of the explanation in the book is that the mechanism of unidirectional rotation of the central shaft in F1-ATPase is discussed in detail on the basis of this new view. The hydration entropy of each β subunit to which a specific chemical compound (ATP, ADP and Pi, Pi, or nothing) is bound, the hydration entropy of the α3β3 complex, and the dependence of the hydration entropy of F1-ATPase on the orientation of the γ subunit play essential roles.

Mechanism of Plant Hormone Signaling under Stress

by Girdhar K. Pandey

Plant hormone signaling plays an important role in many physiological and developmental processes including stress response. With the advent of new post-genomic molecular techniques, the potential for increasing our understanding of the impact of hormone signaling on gene expression and adaptive processes has never been higher. Unlocking the molecular underpinnings of these processes shows great promise for the development of new plant biotechnologies and improved crop varieties. The topics included in this book emphasize on genomics and functional genomics aspects, to understand the global and whole genome level changes upon particular stress conditions. With the functional genomics tools, the mechanism of phytohormone signaling and their target genes can be defined in a more systematic manner. The integrated analysis of phytohormone signaling under single or multiple stress conditions may prove exceptional to design stress tolerant crop plants in the field conditions. Bringing together the latest advances, as well as the work being done to apply these findings to plant and crop science, Mechanism of Plant Hormone Signaling Under Stress will prove extremely useful to plant and stress biologists, plant biotechnology researchers, as well as students and teachers.

Mechanisms for CO2 Sequestration in Geological Formations and Enhanced Gas Recovery

by Roozbeh Khosrokhavar

This book gives background information why shale formations in the world are important both for storage capacity and enhanced gas recovery (EGR). Part of this book investigates the sequestration capacity in geological formations and the mechanisms for the enhanced storage rate of CO2 in an underlying saline aquifer. The growing concern about global warming has increased interest in geological storage of carbon dioxide (CO2). The main mechanism of the enhancement, viz. , the occurrence of gravity fingers, which are the vehicles of enhanced transport in saline aquifers, can be visualized using the Schlieren technique. In addition high pressure experiments confirmed that the storage rate is indeed enhanced in porous media. The book is appropriate for graduate students, researchers and advanced professionals in petroleum and chemical engineering. It provides the interested reader with in-depth insights into the possibilities and challenges of CO2 storage and the EGR prospect.

Mechanisms for Long-Term Innovation: Technology and Business Development of Reverse Osmosis Membranes (Advances in Japanese Business and Economics #31)

by Masatoshi Fujiwara Yaichi Aoshima

This book explores how a long-term innovation can take place based on historical analyses of the development of reverse osmosis (RO) membrane from the early 1950s to the mid-2010s. The RO membrane is a critical material for desalination that is a key to solve water shortages becoming serious in many places of the world. The authors conducted in-depth field studies as well as analyses of rich archival data to demonstrate how researchers, engineers, managers, entrepreneurs, and policymakers interacted each other for this material innovation to be realized. A series of historical analyses in this book uncovered that initial government supports, strategic niche markets, emergence of breakthrough technology, and company-specific rationales played significant roles for companies to overcome four types of uncertainty, technological, market, competition, and social/organizational ones, and enabled the companies to persistently invest in the development and commercialization of the RO membrane. This book depicts that innovation does not arise on a sudden, but that it is actualized through long lasting process with turns and twists, which is driven by many non-economic rationales beyond economic motives.

Mechanisms in Molecular Biology (Elements in the Philosophy of Biology)

by Tudor Baetu

The new mechanistic philosophy is divided into two largely disconnected projects. One deals with a metaphysical inquiry into how mechanisms relate to issues such as causation, capacities and levels of organization, while the other deals with epistemic issues related to the discovery of mechanisms and the intelligibility of mechanistic representations. Tudor Baetu explores and explains these projects, and shows how the gap between them can be bridged. His proposed account is compatible both with the assumptions and practices of experimental design in biological research, and with scientifically accepted interpretations of experimental results.

Mechanisms in Science: Method or Metaphysics?

by Stavros Ioannidis Stathis Psillos

In recent years what has come to be called the 'New Mechanism' has emerged as a framework for thinking about the philosophical assumptions underlying many areas of science, especially in sciences such as biology, neuroscience, and psychology. This book offers a fresh look at the role of mechanisms, by situating novel analyses of central philosophical issues related to mechanisms within a rich historical perspective of the concept of mechanism as well as detailed case studies of biological mechanisms (such as apoptosis). It develops a new position, Methodological Mechanism, according to which mechanisms are to be viewed as causal pathways that are theoretically described and are underpinned by networks of difference-making relations. In contrast to metaphysically inflated accounts, this study characterises mechanism as a concept-in-use in science that is deflationary and metaphysically neutral, but still methodologically useful and central to scientific practice.

Mechanisms of Arsenic Toxicity and Tolerance in Plants

by Mirza Hasanuzzaman Kamrun Nahar Masayuki Fujita

Arsenic is likely the most talked-about metalloid in the modern world because of its toxic effects on both animal and plants. Further, arsenic pollution is now producing negative impacts on food security, especially in many south Asian countries. Since plants are a major food source, their adaptation to As-rich environments is essential, as is being informed about recent findings on multifarious aspects of the mechanisms of arsenic toxicity and tolerance in plants. Although numerous research works and review articles have been published in journals, annual reviews and as book chapters, to date there has been no comprehensive book on this topic.This book contains 19 informative chapters on arsenic chemistry, plant uptake, toxicity and tolerance mechanisms, as well as approaches to mitigation. Readers will be introduced to the latest findings on plant responses to arsenic toxicity, various tolerance mechanisms, and remediation techniques. As such, the book offers a timely and valuable resource for a broad audience, including plant scientists, soil scientists, environmental scientists, agronomists, botanists and molecular biologists.

Mechanisms of Everyday Cognition

by James M. Puckett Hayne W. Reese

Based on the proceedings of the twelfth biennial conference on life-span developmental psychology, most of the contributions in this volume deal with the mechanisms of everyday cognition. However, a broad spectrum of additional concerns is addressed within the domain of everyday cognition: its metatheoretical underpinnings, theory and theoretical issues, methods of investigation, empirical considerations, and social issues and applications. Addressing everyday cognition in infancy, childhood, adolescence, young and middle adulthood, and old age, this book is consistent with the chronological life-span theme of this series. The contributors collectively discuss some of the traditional concerns of life-span psychology: the dialectical nature of everyday cognition, individual differences, and contextual influences. Leading and concluding chapters provide overview, integration, and summary. In bringing together a wide array of age periods and points of view within the domain of everyday cognition, the editors hope that students and researchers in developmental psychology and cognitive science will find a useful cross-fertilization of ideas. A huge variety of theoretical perspectives is presented ranging from the position that everyday cognition and academic (laboratory) cognition are different manifestations of the same underlying processes to the position that the underlying processes are completely separate. Also of importance, a large assortment of research methods is illustrated including interviews, laboratory simulations, real-life observations and psychometric methods.

Mechanisms of Forest Ecosystems Sustainability in a Changing Climate: Complete Triad of Ecological Monitoring

by Erland G. Kolomyts

The author's working concept of geo-ecological monitoring is presented. For the first time, the full triad of monitoring in its classical definition is considered: "observation (state assessment) – control (prediction) – management (adaptation, feedback, regulation)". The strategic goal of described monitoring research is to reveal the environmental otential of sustainablility of forest ecosystems in the context of modern global warming. The monograph expounds the main statements of author’s topo-ecological predictive concept: “Global Changes on the Local Level”, as a basis of ground bio-ecological and geosystem monitoring of natural ecosystems under global anthropogenic climatic changes. This concept makes it possible to carry out local empirical simulation of the regional bioclimatic trend and thereby reveal the mechanisms of transmission of global and regional climate signals to the local level. On the example of the Volga River basin, predictive empirical-statistical models of the carbon balance of forest ecosytems are presented under conditions of a changing climate. The carbon content in various pools of boreal and nemoral forests were calculated. The global climate models give prognostic estimates of the components of them carbon balance. A quantitative assessment of the ecological resources of forest formations that provide the environment sustainability through mechanisms of regulation of the carbon cycle is given. The adaptation of forest ecosystems to climate change is described through the calculated parameters of their functional sustainability.

Mechanisms of Gene Regulation

by Ferdinand Molnár Carsten Carlberg

This textbook aims to describe the fascinating area of eukaryotic gene regulation for graduate students in all areas of the biomedical sciences. Gene expression is essential in shaping the various phenotypes of cells and tissues and as such, regulation of gene expression is a fundamental aspect of nearly all processes in physiology, both in healthy and in diseased states. This pivotal role for the regulation of gene expression makes this textbook essential reading for students of all the biomedical sciences, in order to be better prepared for their specialized disciplines. A complete understanding of transcription factors and the processes that alter their activity is a major goal of modern life science research. The availability of the whole human genome sequence (and that of other eukaryotic genomes) and the consequent development of next-generation sequencing technologies have significantly changed nearly all areas of the biological sciences. For example, the genome-wide location of histone modifications and transcription factor binding sites, such as provided by the ENCODE consortium, has greatly improved our understanding of gene regulation. Therefore, the focus of this book is the description of the post-genome understanding of gene regulation. The purpose of this book is to provide, in a condensed form, an overview on the present understanding of the mechanisms of gene regulation. The authors are not aiming to compete with comprehensive treatises, but rather focus on the essentials. Therefore, the authors have favored a high figure-to-text ratio following the rule stating that "a picture tells more than thousand words". The content of the book is based on the lecture course, which is given by Prof. Carlberg since 2001 at the University of Eastern Finland in Kuopio. The book is subdivided into 4 sections and 13 chapters. Following the Introduction there are three sections, which take a view on gene regulation from the perspective of transcription factors, chromatin and non-coding RNA, respectively. Besides its value as a textbook, Mechanisms of Gene Regulation will be a useful reference for individuals working in biomedical laboratories.

Mechanisms of Genome Protection and Repair (Advances in Experimental Medicine and Biology #1241)

by Dmitry O. Zharkov

DNA is under constant challenge from environmental and endogenous metabolic assaults. Several layers of defence and repair systems allow cells to maintain stable genomes; in humans, dysfunction of these systems leads to cancer, neurodegeneration, and other pathologies. At the same time, recently it had emerged that targeted and regulated DNA damage and repair is a mechanism underlying several important cellular processes such as epigenetic demethylation and immunoglobulin gene diversification. The present collection of papers is aimed to cover new developments in the area of protective and regulatory mechanisms associated with DNA damage. The mechanisms ruling the recognition of damaged nucleotides against the vast background of normal ones are reviewed. The role of extended non-catalytic domains that are often found in eukaryotic DNA repair proteins in contrast to their downsized, catalytic-only bacterial counterparts is discussed. Among the proposed subjects are the regulatory functions of bulky covalent modifications such as poly(ADP)ribosylation and ubiquitylation in DNA damage response, especially in the context of chromatin remodelling. As opposed to DNA repair, damage tolerance allows cells to replicate with lesions in the genome; the enzymes responsible are also covered. Finally, we present examples of modern multilevel understanding of the cell function and malfunction in the wake of genotoxic assaults such as oxidative stress, abiotic environmental stress, and DNA-damaging plant toxins.

Mechanisms of Mineralization of Vertebrate Skeletal and Dental Tissues

by Irving M. Shapiro William J. Landis

The book presents a multi-disciplinary approach to understanding mechanisms regulating the formation of mineral in vertebrate skeletal and dental tissues. The focus of the book is directed toward the mineralization process, an evolutionarily conserved system in which cells synthesize a complex and unique extracellular matrix into which mineral is deposited. Regulatory control is viewed though lenses that emphasize the genetic, physical-chemical, biochemical, structural, cellular and extracellular aspects of the mineralization process as they relate to crystal nucleation, growth and maturation. Throughout the book, defects in regulation at the genetic and transcriptional levels are linked to the numerous clinical problems associated with the mineralization of bone, cartilage, tendon, tooth, and soft tissues. The book serves as a comprehensive text for basic scientists and scholars working in the many areas that comprise hard tissue research, as well as undergraduate and graduate students, postdoctoral fellows and those contemplating working in the field of biomineralization or who need a review of a specific mineralization topic. The information contained in the book is relevant for clinicians and clinical scientists in the fields of orthopaedic surgery, veterinary medicine, dentistry, endocrinology, aging and genetics.
