Genetically Engineered Crops by National Academies of Sciences, Engineering, and Medicine,Division on Earth and Life Studies,Board on Agriculture and Natural Resources,Committee on Genetically Engineered Crops: Past Experience and Future Prospects Pdf
Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Urban Meteorology by National Research Council,Division on Earth and Life Studies,Board on Atmospheric Sciences and Climate,Committee on Urban Meteorology: Scoping the Problem, Defining the Needs Pdf
According to the United Nations, three out of five people will be living in cities worldwide by the year 2030. The United States continues to experience urbanization with its vast urban corridors on the east and west coasts. Although urban weather is driven by large synoptic and meso-scale features, weather events unique to the urban environment arise from the characteristics of the typical urban setting, such as large areas covered by buildings of a variety of heights; paved streets and parking areas; means to supply electricity, natural gas, water, and raw materials; and generation of waste heat and materials. Urban Meteorology: Forecasting, Monitoring, and Meeting Users' Needs is based largely on the information provided at a Board on Atmospheric Sciences and Climate community workshop. This book describes the needs for end user communities, focusing in particular on needs that are not being met by current urban-level forecasting and monitoring. Urban Meteorology also describes current and emerging meteorological forecasting and monitoring capabilities that have had and will likely have the most impact on urban areas, some of which are not being utilized by the relevant end user communities. Urban Meteorology explains that users of urban meteorological information need high-quality information available in a wide variety of formats that foster its use and within time constraints set by users' decision processes. By advancing the science and technology related to urban meteorology with input from key end user communities, urban meteorologists can better meet the needs of diverse end users. To continue the advancement within the field of urban meteorology, there are both short-term needs-which might be addressed with small investments but promise large, quick returns-as well as future challenges that could require significant efforts and investments.
Since the 1970s, much has been learned about the reading process from research by cognitive psychologists. This book summarizes that important work and puts it into a coherent framework.

Extracellular Composite Matrices in Arthropods by Ephraim Cohen,Bernard Moussian Pdf
Emphasis is placed on the elaborate cuticular matrices in insects and crustaceans, spider and insect silks, sialomes of phytophagous and blood-feeding arthropods as well as on secretions of male and female accessory glands. Focus is placed largely on insects, due to the extensive body of published research that in part is the result of available whole genome sequences of several model species (in particular Drosophila melanogaster) and accessible ESTs for other species. Such advances have facilitated fundamental insights into genomic, proteomic and molecular biology-based physiology. This new volume contains comprehensive contributions on extracellular composite matrices in arthropods. The building blocks of such matrices are formed in and secreted by single layered epithelial cells into exterior domains where their final assembly takes place.Additionally, the unique mechanical properties of natural biocomposites like chitin/chitosan, the crustacean mineralized exoskeleton, the pliant protein resilin or insect and spider silks, have inspired basic and applied research that yield sophistical biomimetics and structural biocomposite hybrids important for future industrial and biomedical use. In summary, this book provides an invaluable vast source of basic and applied information for a plethora of scientists as well as textbook for graduate and advanced undergraduate students.

This book is exclusively concerned with wood modification, although many of these processes are generic and can be applied to other lignocellulosic materials. There have been many rapid developments in wood modification over the past decade and, in particular, there has been considerable progress made in the commercialisation of technologies. Topics covered include: The use of timber in the 21st century Modifying the properties of wood Chemical modification of wood: Acetic Anhydride Modification and reaction with other chemicals Thermal modification of wood Surface modification Impregnation modification Commercialisation of wood modification Environmental consideration and future developments This is the first time that a book has covered all wood modification technologies in one text. Although the book covers the main research developments in wood modification, it also puts wood modification into context and additionally deals with aspects of commercialisation and environmental impact. This book is very timely, because wood modification is undergoing huge developments at the present time, driven in part by environmental concerns regarding the use of wood treated with certain preservatives. There has been considerable commercial interest shown in wood modification over the past decade, with products based upon thermal modification, and furfurylation now being actively being marketed. The next few years will see the commercialisation of acetylation and impregnation modification. This is a new industry, but one that has enormous potential. This book will prove useful to all those with an interest in wood modification including researchers, technologists and professionals working in wood science and timber engineering, wood preservation, and well as professionals in the paper and pulp industries, and those with an interest in the development of renewable materials.
