Nitrogen Cycling in the Americas : Natural and Anthropogenic Influences and Controls
The rate of creation of reactive nitrogen (NR) on the earth has dramatically increased in the last half century mainly due to the production of N-fertilizer through the Haber-Bosch process, fossil fuel combustion, and the cultivation of plants that fix N from the atmosphere. The anthropogenic production of NR has been especially high in developed countries of the temperate zone, such as the USA and Canada, where severe eutrophication of estuaries and coastal zones, acidification of lakes and streams, loss of biodiversity, and reduced forest productivity have become common environmental problems associated with increasing nitrogen loads to ecosystems. This book presents a series of studies from across the Americas whose aim is to highlight key natural processes that control nitrogen cycling as well as discuss the main anthropogenic influences on the nitrogen cycle in both the tropical and temperate regions of the Americas.
Natural Disasters as Interactive Components of Global-Ecodynamics
This book opens a new approach to the study of global environmental changes having unfavourable character for mankind and other living systems. The main advantage of the book consists in the accumulation of knowledge from different sciences to parametrize the global ecodynamic process. Natural catastrophes are considered as an interactive element of global natural dynamics which are described by means of simulation models of global nature/society. The realization of this approach allows the integration within a complex structure of all international and national means of environmental monitoring and provides a tool for objective evaluation of the environmental quality. The main purpose of this book is to develop a universal information technology to estimate the state of environmental subsystems functioning under various climatic and anthropogenic conditions.

Models, Methods and Tools for Product Service Design : The Manutelligence Project
This book summarizes research being pursued within the Manutelligence project, the goal of which is to help enterprises develop smart, social and flexible products with high value added services. Manutelligence has improved Product and Service Design by developing suitable models and methods, and connecting them through a modular, collaborative and secure ICT Platform. The use of real data collected in real time by Internet of Things (IoT) technologies underpins the design of product-service systems and makes it possible to monitor them throughout their life cycle. Available data allows costs and sustainability issues to be more accurately measured and simulated in the form of Life Cycle Cost (LCC) and Life Cycle Assessment (LCA). Analysing data from IoT systems and sharing LCC and LCA information via the ICT Platform can help to accelerate the design of product-service systems, reduce costs and better understand customer needs. Industrial partners involved in Manutelligence provide a clear overview of the project's outcomes, and demonstrate how its technological solutions can be used to improve the design of product-service systems and the management of product-service life cycles.
Modeling Theory in Science Education
The book focuses as much on course content as on instruction and learning methodology, and presents practical aspects that have repeatedly demonstrated their value in fostering meaningful and equitable learning of physics and other science courses at the secondary school and college levels.The author shows how a scientific theory that is the object of a given science course can be organized around a limited set of basic models. Special tools are introduced, including modeling schemata, for students to meaningfully construct models and required conceptions, and for teachers to efficiently plan instruction and assess and regulate student learning and teaching practice. A scientific model is conceived to represent a particular pattern in the structure or behavior of physical realities and to explore and reify the pattern in specific ways. The author further shows how to engage students in modeling activities through structured learning cycles.

Islamic banking and finance
Explores the nature and role of money in modern economies and elaborates on the process of credit deposit creation, trade cycles and instruments for the creation of value in financial markets through the perspectives of Islamic finance. The author explains its characteristics, especially the rationale for the lack of interest-based financial activities. He examines the intrinsic ethical and humanistic frameworks that govern financial theories and practices and the models for the creation of value, risk-sharing and socially responsible investing, as well as the governance and regulation that these systems follow. The author also does a comparative assessment of conventional financial systems with Islamic finance with relevant examples, assesses the performance of Islamic systems and examines existing and expanding markets for Islamic finance.
International Trade and Multinational Activity : Heterogeneity of Firms, Incentives for Foreign Direct Investment, and International Business Cycle Dynamics
During the last 25 year, the neoclassical Heckscher-Ohlin trade theory has been extended to the ‘new’ trade theory by including imperfect competition and fixed costs into the analysis of trade relations. Furthermore, these micro-oriented trade models are increasingly used to analyze macro-oriented questions. Chapter 2 of this study investigates the dynamic welfare effects of exposure to trade in a new trade model, which is extended by firm heterogeneity.

Heterocycles from Carbohydrate Precursors
This book is a volume in the series Topics in Heterocyclic Chemistry.Itc- ers the key methods used for designing synthetic approaches to heterocycles from carbohydrates and the value and scope of these methods. Carbohydrates are widely distributed in nature and constitute the largest part of renewable biomasses. Moreover, many carbohydrates and their derivatives are comm- cially available at relatively cheap prices. Consequently their utilization is highly encouraged and economically they are of great signifcance. Moreover, carbohydrates are highly functionalized compounds that can be readily deritized and/or cyclized to provide heterocyclic compounds. This book provides a modern account and an up-to-date description of the advancement in the synthesis of diverse heterocycles from carbohydrates. Carbohydrates can be considered as a source of chiral centers in addition to the variable modifcation thereof.

In this volume, for the first time, the relationship between biodiversity and ecosystem processes in forests is thoroughly explored. The text examines the multiple effects of tree diversity on productivity and growth, biogeochemical cycles, animals, pests, and disturbances.
Experimenting with Dynamic Macromodels : Growth and Cycles
This book presents a macroeconomic dynamic model à la Solow-Swan, including the market for labour, in a discrete time structure. Labour supply is modelled as a reversed S curve (derived in the appendix). The models are expanded to include expenditure on R&D (thus endogenous technical progress), and public expenditure on infrastructures. For each of the three models, numerical simulations are implemented in MAPLE, and the results are shown in time series figures, which make it easy to detect that even small changes in the parameters produce responses in the time behaviour of the main variables: from steady growth, to regular cycles, to chaotic-like time paths. The simulations show that cycles do not promote material welfare, as measured by total undiscounted consumption along the time horizon, and that the comparative action of R&D versus public expenditure is strictly linked to the values assigned to the parameters.
