Download or read book Molecules in Time and Space written by Miguel Vicente and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade a wealth of new data has arisen from the use of new fluorescent labelling techniques and the sequencing of whole microbial genomes. One important conclusion from these data is that bacterial cells are much more structured than previously thought. The wall and the outer membrane contain topological domains, some proteins localize or move in specific patterns inside the cells, and some genes appear clustered in the chromosome and form conserved evolutionary units. Many of these structures are related to the cell cycle and to the process of cell morphogenesis, two processes that are themselves related to each other. From these observations the dcw gene cluster appears as a phylogenetic trait that is mainly conserved in bacilli. Molecules in Time and Space reviews the data on the formation of subcellular patterns or structures in bacteria, presents observations and hypotheses on the establishment and the maintenance of cell shape, and on the organization of genetic information in the chromosome.

Download or read book Order from Force written by Jeffrey H Williams and published by Morgan & Claypool Publishers. This book was released on 2015-12-01 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present theme concerns the forces of nature, and what investigations of these forces can tell us about the world we see about us. The story of these forces is long and complex, and contains many episodes that are not atypical of the bulk of scientific research, which could have achieved greater acclaim 'if only...'. The intention of this book is to introduce ideas of how the visible world, and those parts of it that we cannot observe, either because they are too small or too large for our scale of perception, can be understood by consideration of only a few fundamental forces. The subject in these pages will be the authority of the commonly termed, laws of physics, which arise from the forces of nature, and the corresponding constants of nature (for example, the speed of light, c, the charge of the electron, e, or the mass of the electron, me).

Download or read book Governing Molecules written by Herbert Gottweis and published by MIT Press. This book was released on 1998-12-10 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists, investors, policymakers, the media, and the general public have all displayed a continuing interest in the commercial promise and potential dangers of genetic engineering. In this book, Herbert Gottweis explains how genetic engineering became so controversial—a technology that some seek to promote by any means and others want to block entirely. Beginning with a clear exposition of poststructuralist theory and its implications for research methodology, Gottweis offers a novel approach to political analysis, emphasizing the essential role of narratives in the development of policy under contemporary conditions. Drawing on more than eighty in-depth interviews and extensive archival work, Gottweis traces today's controversy back to the sociopolitical and scientific origins of molecular biology, paying particular attention to its relationship to eugenics. He argues that over the decades a number of mutually reinforcing political and scientific strategies have attempted to turn genes into objects of technological intervention—to make them "governable." Looking at critical events such as the 1975 Asilomar conference in the United States, the escalating conflict in Germany, and regulatory disputes in Britain and France during the 1980s, Gottweis argues that it was the struggle over boundaries and representations of genetic engineering, politics, and society that defined the political dynamics of the drafting of risk regulations in these countries. In a key chapter on biotechnology research, industry, and supporting technology policies, Gottweis demonstrates that the interpretation of genetic engineering as the core of a new "high technology" industry was part of a policy myth and an expression of identity politics. He suggests that under postmodern conditions a major strategy for avoiding policy failure is to create conditions that ensure tolerance and respect for the multiplicity of socially available policy narratives and reality interpretations.

Download or read book Timetrees Incorporating Fossils and Molecules 2nd edition written by Michel Laurin and published by Frontiers Media SA. This book was released on 2022-09-15 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calibrating phylogenies to time is central to addressing many questions in evolutionary biology and macroevolution. The fossil record once provided our only source for establishing a timeline for evolution. However, the incompleteness of the fossil record and the non-uniformity of fossil recovery rate make it challenging to obtain precise estimates of divergence times from fossil evidence alone. Molecular dating, which combines evidence from the geological and molecular records, enables us to generate a much more complete and precise timeline of events. The molecular clock can be time-calibrated using temporal evidence from fossils and used to estimate divergence times based on the assumption that the rate of sequence evolution will be approximately constant over time and among lineages. Methodological challenges to applying this concept in practice have been to relax the assumption of constant evolutionary rates and to model the uncertainty associated with paleontological and geological calibrations. To this end, available statistical methods have become increasingly complex in order to capture key features of empirical data. These are typically applied using Bayesian inference, which provides a powerful framework for incorporating multiple sources of uncertainty. Although overall more effort has been expended in developing models of molecular sequence evolution, critical advances have also included approaches to modeling taxonomic diversification and fossilization. In particular, recent advances in birth-death process models have allowed for continuous sampling along lineages, enabling more information from the fossil record to be incorporated into dating analyses in a statistically coherent way. In addition, available dating methods can now be applied to scenarios in which no molecular data may be available, allowing for novel insights into the evolution of entirely extinct clades. Other recent innovations enable us to date divergence times among taxa that have no fossil record, including the use of gene duplication events or biogeographic evidence. Furthermore, time-calibrated trees are necessary for obtaining phylogenetic estimates of taxonomic diversification and extinction rates, which can now be jointly inferred along with lineage divergence times. These approaches offer an exciting opportunity to understand the evolution of life in deep time, although key challenges remain, especially with regards to modeling the processes of genome evolution, taxonomic diversification and fossil recovery. In this Research Topic, we focus on recent advances in methodology, outstanding challenges, and the application of molecular and paleontological dating methods to empirical case studies across the Tree of Life.

Download or read book Molecules and the Chemical Bond written by Henry A. Bent and published by Trafford Publishing. This book was released on 2013-09-30 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: MOLECULES and the Chemical Bond is about understanding Schrdingers equation, for chemical systems. In his famous Lectures on Physics, Richard Feynman quotes Paul Dirac on what it means to understand an equation. I understand what an equation means, said Dirac, if I have a way of figuring out the characteristics of its solutions without actually solving it. That hits the nail on the head! Its precisely what Conceptual Valence Bond Theory does for Schrdingers equation. A physical understanding of an equation, adds Feynman, is a completely unmathematical, imprecise, and inexact thing, but absolutely necessary for a physicist. It unfolds in MCB in two stages, described by Newton as a stage of Analysis (a union of observations and inductions) and a stage of Synthesis (use of inductions, accepted as first principles, to explain observations). The books chief vehicle for creating an intuitive understanding of solutions of Schrdingers equation is the worlds largest and to the authors knowledge, virtually only library of line drawings of exclusive orbital models of chemical species electron density profiles. By focussing attention on fundamental physical principles and by avoiding use of atomic orbitals and, thereby, mathematical complexities associated with Schrdingers equation (the only source of atomic orbitals), the books essays provide a scientifically sound, student-friendly introduction to modern valence theory. Repetition of fundamental ideas, here and there, is intended to make individual essays understandable and interesting, each by itself, so that readers may examine them in any order, in leisurely walks, so to speak, in the big garden that is valence theory, picking bouquets to their liking.

This book was released on 2012-12-06 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute (ASI) on "Relativistic Effects in Atoms, Molecules and Solids" cosponsored by Simon Fraser University (SFU) and Natural Sciences and Engineering Research Council of Canada (NSERC) was held at the University of British Columbia (UBC) , Van couver, Canada from August 10th until August 21st, 1981. A total of 77 lecturers and students with diverse backgrounds in Chemistry, Physics, Mathematics and various interdisciplinary subjects attended the ASI. In the proposal submitted to NATO for financial support for this ASI, it was suggested that recent impressive experimental developments coupled with the availability of sophisticated computer technology for detailed investigation of the relativistic structure of atoms, molecules and solids would provide an excellent testing ground for the validity and accuracy of the theoretical treatment of the rela tivistic many-electron systems involving medium and heavy atoms. Such systems are also of interest to the current energy crisis because of their usage for photovoltaic devices, nuclear fuels (UF6), fusion lasers (Xe*2)' catalysts for solar energy conversion, etc.
