This book presents an in-depth look at US infrastructure and its challenges in the 21st century. While infrastructure has received considerable attention in recent years, much of the discussion has concentrated on physical, economic, or noneconomic conditions. The Trump administration has heightened interest in the topic, promising infrastructure spending during his tenure, yet little demonstrable progress has been made. This book brings together a multi-disciplinary perspective—structural, technological, economic, financial, political, planning, and policy—that has been largely absent in discussions on the subject, to provide a clearer and broader understanding of the challenges facing US infrastructure. The book is divided into three parts: Part I looks at the challenges from a structural, technological, and sustainability perspective; Part II from an economic, productivity, and finance perspective; and Part III from an institutional, security, and political perspective.Written primarily for policy makers, managers, and administrators in public and private organizations, as well as individuals and academics with an interest in the future of US infrastructure, this book provides an in-depth analysis of the US infrastructure problem, its causes and consequences, and suggests timely, specific measures that may be taken at the state, local, and federal levels to improve and better secure our roads, transit, public buildings, economy, and technology.

Plant Secondary Metabolites provides reliable assays that will equip researchers to meet the unprecedented challenge of fulfilling the huge demand for feed driven by increasing demand of animal protein in developing countries. Using more than a decade of experience working with the quantification of plant secondary metabolites, the authors have created a manual allowing for the safe and efficient use of locally available feed resources. This comprehensive new volume also offers readers a better understanding of plant-animal interactions. The methodologies provided in this volume may also be used to determine plant secondary metabolites in human food and in studying the implications of their consumption on human health and welfare.This volume contains methods for analysis of some important plant secondary metabolites, which may be conducted in laboratories equipped with basic facilities. The chemical nature of plant secondary metabolites and their known physiological effects and mechanisms of action are also briefly presented. The methods have been written in a recipe-like format designed for direct practical use in the laboratory. Authoritative and extensive, Plant Secondary Metabolites will become an essential reference for plant biologists, biochemists, and molecular and cell biologists.

Over the last decade, Computational Fluid Dynamics (CFD) has become a - ture technology for the development of new products in aeronautical industry. Aerodynamic design engineers have progressively taken advantage of the pos- bilities o?ered by the numericalsolutionof the Reynolds averagedNavier-Stokes (RANS) equations. Signi?cant improvements in physical modeling and solution algorithms as well as the enormous increase of computer power enable hi- ?delity numerical simulations in all stages of aircraft development. In Germany, the national CFD project MEGAFLOW furthered the dev- opment and availability of RANS solvers for the prediction of complex ?ow problemssigni?cantly. MEGAFLOWwasinitiated by the?rstaviationresearch programoftheFederalGovernmentin1995undertheleadershipoftheDLR(see Kroll, N. , Fassbender, J. K. (Eds). : MEGAFLOW - Numerical Flow Simulation for Aircraft Design; Notes on Numerical Fluid Mechanics and Multidisciplinary Design, Volume 89, Springer, 2005). A network from aircraft industry, DLR and several universities was created with the goal to focus and direct development activities for numerical ?ow simulation towards a common aerodynamic si- lation system providing both a block-structured (FLOWer-Code) and a hybrid (TAU-Code) parallel ?ow prediction capability. Today, both codes have reached a high level of maturity and reliability. They are routinely used at DLR and German aeronautic industry for a wide range of aerodynamic applications. For many universities the MEGAFLOW software represents a platform for the - provementofphysicalmodelsandfortheinvestigationofcomplex?owproblems. The network was established as an e?cient group of very closely co-operating partners with supplementing expertises and experience.
