Различные книги в жанре БиологияChemistry of the Solar System
This book is an appealing, concise, and factual account of the chemistry of the solar system. It includes basic facts about the chemical composition of the different bodies in the solar system, the major chemical processes involved in the formation of the Sun, planets, and small objects, and the chemical processes that determine their current chemical make-up. The book summarizes compositional data but focuses on the chemical processes and where relevant, it also emphasizes comparative planetology. There are numerous informative summary tables which illustrate the similarities (or differences) that help the reader to understand the processes described. Data is presented in graphical form which is useful for identifying common features of the major processes that determine the current chemical state of the planets. The book will interest general readers with a background in chemistry who will enjoy reading about the chemical diversity of the solar system's objects. It will serve as an introductory textbook for graduate classes in planetary sciences but will also be very popular with professional researchers in academia and government, college professors, and postgraduate fellows.
Green Analytical Chemistry
Concerns about environmental pollution, global climate change and hazards to human health have increased dramatically. This has led to a call for change in chemical processes including those that are part of chemical analysis. The development of analytical chemistry continues and every new discovery in chemistry, physics, molecular biology, and materials science brings new opportunities and challenges. Yet, contemporary analytical chemistry does not consume resources optimally. Indeed, the usage of toxic chemical compounds is at the highest rate ever. All this makes the emerging field of green chemistry a “hot topic” in industrial, governmental laboratories as well as in academia. This book starts by introducing the twelve principles of green chemistry. It then goes on to discuss how the principles of green chemistry can be used to assess the ‘greenness’ of analytical methodologies. The ‘green profile’ proposed by the ACS Green Chemistry Institute is also presented. A chapter on “Greening” sample preparation describes approaches to minimizing toxic solvent use, using non-toxic alternatives, and saving energy. The chapter on instrumental methods describes existing analytical approaches that are inherently green and making non-green methods greener. The final chapter on signal acquisition describes how quantitative structure-property relationship (QSPR) ideas could reduce experimental work thus making analysis greener. The book concludes with a discussion of how green chemistry is both possible and necessary. Green Analytical Chemistry is aimed at managers of analytical laboratories but will also interest teachers of analytical chemistry and green public policy makers.
Atmospheric Chemistry
Atmospheric Chemistry provides readers with a basic knowledge of the chemistry of Earth's atmosphere, and an understanding of the role that chemical transformations play in this vital part of our environment. The composition of the 'natural' atmosphere (troposphere, stratosphere and mesosphere) is described in terms of the physical and chemical cycles that govern the behaviour of the major and the many minor species present, and of the atmospheric lifetimes of those species. An extension of these ideas leads to a discussion of the impacts of Man's activities on the atmosphere, and to an understanding of some of the most important environmental issues of our time. One thread of the book explains how living organisms alter the composition and pressures in the atmosphere, modify temperatures, and change the intensity and wavelength-distribution of light arriving from the Sun. Meanwhile, the living organisms on Earth have depended on these very same environmental conditions being satisfactory for the maintenance and evolution of life. There thus appear to be two-way interactions between life and the atmosphere. Man, just one species of living organism, has developed an unfortunate ability to interfere with the feedbacks that seem to have maintained the atmosphere to be supportive of surface life for more than 3.5 billion years. This book will help chemists to understand the background to the problems that arise from such interference. The structure of the book and the development of the subject deviate somewhat from those usually encountered. Important and recurring concepts are presented in outline first, before more detailed discussions of the atmospheric behaviour of specific chemical species. Examples of such themes are the sources and sinks of trace gases, and their budgets and lifetimes. That is, the emphasis is initially on the principles of the subject, with the finer points emerging at later points in the book, sometimes in several successive chapters. In this way, some of the core material gets repeated exposure, but in new ways and in new contexts. The book is written at a level that makes it accessible to undergraduate chemists, and in a manner that should make it interesting to them. However, the material presented forms a solid base for those who are extending their studies to a higher level, and it will also provide non-specialists with the background to an understanding of Man's several and varied threats to the atmosphere. Well-informed citizens can then better assess measures proposed to prevent or alleviate the potential damage, and policy makers more realistically formulate the necessary controls on a sound scientific foundation.
Chemistry in the Kitchen Garden
Over the past decade there has been a resurgence of interest in growing fruit and vegetables in the garden and on the allotment. Part of the driving force behind this is an increased awareness of the health benefits that can be derived from fruit and vegetables in the diet. The 'five helpings a day' dictum reflects the correlation between a regular consumption of fruit and vegetables and a reduced incidence of, for example, cardiovascular disease and some cancers. Growing your own vegetables provides the opportunity to harvest them at their peak, to minimize the time for post-harvest deterioration prior to consumption and to reduce their 'food miles'. It also provides an opportunity to grow interesting and less common cultivars. The combination of economic advantages and recreational factors add to the pleasure of growing fruit and vegetables. This book covers the natural products that have been identified in common 'home-grown' fruit and vegetables and which contribute to their organoleptic and beneficial properties. Over the last fifty years the immense advances in separation methods and spectroscopic techniques for structure elucidation have led to the identification of a wide range of natural products in fruit and vegetables. Not only have many of their beneficial properties been recognized but also their ecological roles in the development of plants have been identified. The functional role of many of these natural products is to mediate the balance between an organism and its environment in terms of microbial, herbivore or plant to plant interactions. The book is aimed at readers with a chemical background who wish to know a little more about the natural products that they are eating, their beneficial effects, and the roles that these compounds have in nature. Developments in the understanding of the ecological and beneficial chemistry of fruit and vegetables have made the exploration of their chemical diversity a fascinating and expanding area of natural product chemistry and readers will obtain some 'taste' for this chemistry from the book. It develops in more detail the relevant sections from the earlier RSC book 'Chemistry in the Garden'. The book begins with an outline of the major groups of compound that are found in fruit and vegetables. This is followed by a description of aspects of environmental chemistry that contribute to the successful cultivation of these crops. Subsequent chapters deal with individual plants which are grouped in terms of the part of the plant, roots, bulbs and stems, leaves, seeds, that are used for food. The final chapters deal with fruit and herbs. The epilogue considers some general aspects of ecological chemistry and climatic stress which may, in the future, affect the growth of fruit and vegetables in the garden particularly in the context of potential climate changes. The book concludes with a section on further reading, a glossary of terms used in plant chemistry and a list of the common fruit and vegetables grouped in their plant families.
Fat Chemistry
Currently, the health of over half the adult population in the UK suffers because of fat. The UK is not alone: obesity is a global problem, but the populations of some countries are heavier than others. This book probes the chemistry of fat in our bodies, providing a unique insight into understanding obesity, and how this material becomes accumulated to cause obesity with particular emphasis on the contribution of nutrition beyond calories. It visits the current hot topic of the genetic origins of obesity and progresses through to the relatively under publicised field of epigenetics, emphasising its importance to understanding the current epidemic. Coming in the wake of the establishment of international collaborations, the book aims to quantify the extent of the contribution of nutritional deficiencies to body weight gain. Yet even before these studies begin some important links have been identified and the molecular mechanisms by which they induce obesity have been mapped. This information reveals a serious problem for the next generation, but it is expected to provide the necessary information to tackle the obesity epidemic. Based on an extensive review of scientific literature, this topical book is written in a way that is accessible to the non-specialist. Suitable for the general public, the principal focus of the book is to advance the public understanding and awareness of science through the high interest subject of obesity. However, many universities recommend public understanding of science texts to students as a means of broadening general knowledge and as a means to emphasise to students the importance of communicating their research to the public. This book will be instrumental in developing this knowledge.
Pulse Chemistry and Technology
Like cereal, pulse processing is one of the oldest and most important of all food processing, which encompasses a diverse range of products. Pulses are widely grown throughout the world and their dietary and economic importance is globally appreciated and well recognized. Although cereal processing has several dedicated text books, no dedicated text on pulse processing is currently available for food science and technology graduates. This book aims to address this oversight, starting with a chapter highlighting the importance of pulses, their production and consumption trends. The coverage in subsequent chapters provides details on the physical and chemical characteristics of pulses, starches, proteins and minor constituents in them and then how they are processed and used. Cooking quality, analysis and the value of the food products will all be examined with the final chapter reviewing the regulatory and legislative requirements for pulses. This book will serve as a comprehensive text book for undergraduate and postgraduate students, educators, industry personnel involved with grain processing and to some extent researchers providing an up-to-date insight into pulse science, processing and technology.
The Chemistry of Plants
This book is an introduction to organic chemistry and its compounds as related to plants. Chemistry tends to be seen as a field that is hard to comprehend and that has few connections with the living world. This book fills a gap as it eases access to organic chemistry by connecting it with plants and includes numerous photos and other illustrations. The book is a combination of organic chemistry with the living world of plants and is an introduction to organic plant compounds for the non-chemist. It starts with a review of basic concepts of chemistry as they relate to plant life, followed by an introduction to structures of organic compounds, which prepares the reader for the following chapters on primary metabolites and on plant fragrances, pigments, and plant defensive compounds. The final chapter relates plant compounds to human life, with subchapters on foods from plants, medicines, psychoactives, fibers, and dyes. Historic discoveries of plant compounds and their developments to contemporary uses, like modern pharmaceuticals, and a section on genetically modified plants, connect with topics of recent interest. The book leads the serious reader from chemistry basics to complex plant substances and their human uses and plant photos and stories accompany chemistry topics and chemical structures to aid understanding. The author, an organic chemist and plant enthusiast, has taught popular undergraduate college level courses on plant chemistry to non-chemistry majors and numerous field seminars to the general public for more than fifteen years. The book's topics and contents have been taught for many years and have proved successful in providing an understanding of plant compounds, organic compounds, and their importance. The book provides a basis for a better understanding of chemistry and its connections to the world of plants, the natural world in general, and to daily life. It is aimed at non-chemistry undergraduate students and to people in general who are interested in plants and who would like to learn more about them. It addresses an audience with little previous chemistry knowledge, yet, leads the serious reader to an understanding of sometimes complex plant compounds, by providing an introduction to chemistry basics, combining the chemistry with pictures and stories, and using simple, clear language. The book can be used both as a text to introduce organic chemistry as it relates to plants and as a text of reference for more advanced readers.

Essays on the Land, Ecotheology, and Traditions in Africa
The book explores how African Christians in Ghana can think eco-theologically about the nexus of mining, waste pollution, water pollution, and land degradation. In 2017, the government of Ghana banned illegal mining and declared war against any activity that does not complement environmental protection and conservation of natural resources. The Christian church needs academic resources to support the campaign against the destruction of the land, water bodies, and environment. The papers presented generate theological imaginations in shaping the political campaign against the destruction of the land and the environment. Reflection on areas related to the theme includes: «The Concept of Land in the Bible»; «The Christian Church and the Galamsey Menace in West Africa»; «The Fulani Cattle Headsmen and Care for the Land»; «The Bible and the Environment: Towards an Agenda for Eco-theology in African Theological Institutions»; «Stewardship of the Land»; «The Menace of Mining in Ghana»; «Destruction of Water Bodies in Ghana»; and «The Menace of Plastic Waste in Ghana.» This volume will serve as a textbook for theological students, the church, and other governmental agencies.
