Exploring Chemical Concepts Through Theory and Computation

by Shubin Liu

Exploring Chemical Concepts Through Theory and Computation Deep, theoretical resource on the essence of chemistry, explaining a variety of important concepts including redox states and bond types Exploring Chemical Concepts Through Theory and Computation provides a comprehensive account of how the three widely used theoretical frameworks of valence bond theory, molecular orbital theory, and density functional theory, along with a variety of important chemical concepts, can between them describe and efficiently and reliably predict key chemical parameters and phenomena. By comparing the three main theoretical frameworks, readers will become competent in choosing the right modeling approach for their task. The authors go beyond a simple comparison of existing algorithms to show how data-driven theories can explain why chemical compounds behave the way they do, thus promoting a deeper understanding of the essence of chemistry. The text is contributed to by top theoretical and computational chemists who have turned computational chemistry into today’s data-driven and application-oriented science. Exploring Chemical Concepts Through Theory and Computation discusses topics including: Orbital-based approaches, density-based approaches, chemical bonding, partial charges, atoms in molecules, oxidation states, aromaticity and antiaromaticity, and acidity and basicityElectronegativity, hardness, softness, HSAB, sigma-hole interactions, charge transport and energy transfer, and homogeneous and heterogeneous catalysisElectrophilicity, nucleophilicity, cooperativity, frustration, homochirality, and energy decompositionChemical concepts in solids, excited states, spectroscopy and machine learning, and catalysis and machine learning, as well as key connections between related concepts Aimed at both novice and experienced computational, theoretical, and physical chemists, Exploring Chemical Concepts Through Theory and Computation is an essential reference to gain a deeper, more advanced holistic understanding of the field of chemistry as a whole.

Exploring and Optimizing Agricultural Landscapes (Innovations in Landscape Research)

by Lothar Mueller Viktor G. Sychev Nikolai M. Dronin Frank Eulenstein

The book informs about agricultural landscapes, their features, functions and regulatory mechanisms. It characterizes agricultural production systems, trends of their development, and their impacts on the landscape. Agricultural landscapes are multifunctional systems, coupled with all nexus problems of the 21th century. This has led to serious discrepancies between agriculture and environment, and between urban and rural population. The mission, key topics and methods of research in order to understanding, monitoring and controlling processes in rural landscapes is being explained. Studies of international expert teams, many of them from Russia, demonstrate approaches towards both improving agricultural productivity and sustainability, and enhancing ecosystem services of agricultural landscapes. Scientists of different disciplines, decision makers, farmers and further informed people dealing with the evolvement of thriving rural landscapes are the primary audience of this book.

Exploring and Mapping Alaska: The Russian America Era, 1741-1867 (Rasmuson Library Historic Translation)

by Alexey Postnikov Marvin Falk

Russia first encountered Alaska in 1741 as part of the most ambitious and expensive expedition of the entire eighteenth century. For centuries since, cartographers have struggled to define and develop the enormous region comprising northeastern Asia, the North Pacific, and Alaska. The forces of nature and the follies of human error conspired to make the area incredibly difficult to map. Exploring and Mapping Alaska focuses on this foundational period in Arctic cartography. Russia spurred a golden era of cartographic exploration, while shrouding their efforts in a veil of secrecy. They drew both on old systems developed by early fur traders and new methodologies created in Europe. With Great Britain, France, and Spain following close behind, their expeditions led to an astounding increase in the world’s knowledge of North America. Through engrossing descriptions of the explorations and expert navigators, aided by informative illustrations, readers can clearly trace the evolution of the maps of the era, watching as a once-mysterious region came into sharper focus. The result of years of cross-continental research, Exploring and Mapping Alaska is a fascinating study of the trials and triumphs of one of the last great eras of historic mapmaking.

Exploring Agrodiversity (Issues, Cases, and Methods in Biodiversity Conservation)

by Harold Brookfield

Small farmers are often viewed as engaging in wasteful practices that wreak ecological havoc. Exploring Agrodiversity sets the record straight: Small farmers are in fact ingenious and inventive and engage in a diverse range of land-management strategies, many of them resourcefully geared toward conserving resources, especially soil. They have shown considerable resilience in the face of major onslaughts against their way of life by outsiders and government.Using case studies from Africa, Asia, Latin America, and the Pacific, this book provides in-depth analysis of agricultural diversity and explores its history. The book also considers the effect of the "gene revolution" on small farmers and reviews the effects of the "green revolution" in Asian countries. In conclusion, it questions whether the diverse agricultural practices employed by small farmers can survive modern pressures and the global ambitions of the biotechnology industry.

Kids learn how fossils form and about the different types of fossils and the world of long ago--its landscape and the plants and animals that lived then. Scientists use radiometric dating to test fossils to discover when they were made, what organisms made them, what those organisms used for energy, what killed them, and a whole lot of other information. All from rocks! That's a lot of information stored under our feet. Activities include creating plaster fossils, using popcorn to illustrate radiometric dating, and exploring what might have caused mass extinctions by making a lava flow and simulating an asteroid impact. By studying the past, not only do students meet amazing plants and animals, they are also encouraged to consider their own role in geological time to make thoughtful hypotheses about the future.

Explorations in Urban and Regional Dynamics: A case study in complexity science (Routledge Advances in Regional Economics, Science and Policy)

by Joel Dearden Alan Wilson

The task of modelling the evolution of cities – the dynamics – is one of the major challenges of the social sciences. This book presents mathematical and computer models of urban and regional dynamics and shows how advances in computer visualisation provide new insights. Models of non-linear systems in general have three characteristics: multiple equilibria, ‘path dependence’ over time and phase transitions – that is, abrupt change at critical parameter values. These phenomena all exhibit themselves in reality, and it is an ongoing task to match model-based analysis with real phenomena. There are three key features of cities and regions to be represented in models: activities at a location – residence, health, education, work and shopping; flows between locations – spatial interaction; and the structures that carry these activities – buildings, transport and communications networks. Spatial interaction and many elements of activities’ location can be modelled by statistical averaging procedures, which are related to Boltzmann’s methods in statistical mechanics. This is while the evolution of structure can be represented in equations that connect to the Lotka-Volterra equations in ecology. Within this broad framework, alternative approaches can be brought to bear. This book uses entropy-maximising versions of spatial interaction models. The authors explore the dynamics in more detail, using advanced visualisation techniques. These ideas have wide potential uses, and the book illustrates this with applications in history and archaeology.
