    • Inglés
    Environmental and consumer activists have for a long time blamed pesticides, fertilizers and other aspects of intensive farming for causing environmental degradation and human disease. Yet, as the authors in this book show, intensive farming has enabled growth in food production at a rate greater than population growth, thereby ensuring that people are better fed than ever before, whilst simultaneously limiting the effect of farming on the environment.The authors debunk numerous pervasive myths, including:Myth: Pesticides are bad for the environment and bad for human healthFact: Synthetic pesticides enable the production of large quantities of fresh fruit and vegetables, which means that people are better protected against cancer. In addition, the synthetic pesticides themselves are often less toxic than natural pesticides. Overall, synthetic pesticides present a net gain in health terms.Myth: Antibiotic resistance in animals is spreading to humans.Fact: The use of antibiotics in young animals keeps meat prices low and does not materially contribute to antibiotic resistance in humans.Myth: Nitrate fertilizers are a threat to human health.Fact: Nitrate fertilizers are probably beneficial to human health.Myth: Genetically modified organisms (GMOs) are bad for the environment and bad for our health.Fact: Many environmental problems associated with agriculture can be reduced by using GMOs, which have the potential to improve yields and quality which simultaneously reducing associated inputs, such as fertilizers, herbicides and pesticides. Commercially produced GM foodcrops have no known impacts on human health and future GM foodcrops are likely to have health benefits (enabling such things as low-fat chips/french fries and non-allergenic peanuts).Myth: Instances of food poisoning would be reduced if we had more regulations.Fact: Instances of food poisoning in the UK may have been exacerbated by over-cautious government regulation.Myth: Subsidies are needed to order to ensure that food and fish are produced in environmentally sound ways.Fact: Subsidies to fisheries and farming have caused widespread environmental degradation.Myth: Packaging and transporting food is environmentally unfriendly.Fact: Packaging enhances the shelf life of products and reduces wastage during transport. Transporting food allows society to take advantage of different environmental and socio-economic conditions that exist in different places.

A mark of growing maturity is apparent in the coverage of health and safety and related social issues. This is complemented by a clear commitment to the consideration of human factors and the environment. It is hoped that by promoting a wider debate on the matters of future technology and its horizons, on the identification of what industry needs from the research and development community and on building effective partnerships between academia, industry and government, the publication not only addresses the practical commercial obligation to seek robust solutions for today's problems, but will stimulate research for the years to come.

  • Finite Element Techniques in Groundwater Flow Studies

    With Applications in Hydraulic and Geotechnical Engineering

    • Inglés
    The finite element method (FEM) is one of those modern numerical methods whose rise and development was incited by the rapid development of computers. This method has found applications in all the technical disciplines as well as in the natural sciences.One of the most effective applications of the finite element method is its use for the solution of groundwater flow problems encountered in the design and maintenance of hydraulic structures and tailing dams, in soil mechanics, hydrology, hydrogeology and engineering geology.The stimuli to write this book came from the results obtained in the solution of practical problems connected both with the construction and maintenance of fill-type dams and tailing dams and the utilization of groundwater in Czechoslovakia, and on the other hand from the experience gained in teaching hydraulic structures theory at the Faculty of Civil Engineering of the Technical University of Prague. All the experience so far obtained shows markedly the advantages of the finite element method and the great possibilities of its further development as well as its considerable demands on the algorithmization, programming and use of computer possibilities. The reader will find an explanation of the fundamentals of the finite element method directed mainly toward isoparametric elements having an exceptional adaptability and numerical reliability. The finite element method application to groundwater flow concerns mainly two-dimensional problems, which occur most frequently in practice. Considerable attention is given to non-linear and non-stationary problems, which are most important in application.A computer program (based on the eight-noded isoparametric elements) is included and fully documented.The book will be useful to civil engineers, hydrogeologists and engineering geologists who need the finite element method as a solution tool for the complex problems encountered in engineering practice.

  • Limit Analysis in Soil Mechanics

    • Inglés
    During the last ten years, our understanding of the perfect plasticity and the associated flow rule assumption on which limit analysis is based has increased considerably. Many extensions and advances have been made in applications of limit analysis to the area of soil dynamics, in particular, to earthquake-induced slope failure and landslide problems and to earthquake-induced lateral earth pressures on rigid retaining structures. The purpose of the book therefore is in part to discuss the validity of the upper bound work (or energy) method of limit analysis in a form that can be appreciated by a practicing soil engineer, and in part to provide a compact and up-to-date summary of recent advances in the applications of limit analysis to earthquake-induced stability problems in soil mechanics.

    • Inglés
    The goal of image synthesis is to create, using the computer, a visual experience that is identical to what a viewer would experience when viewing a real environment. Radiosity and Realistic Image Synthesis offers the first comprehensive look at the radiosity method for image synthesis and the tools required to approach this elusive goal. Basic concepts and mathematical fundamentals underlying image synthesis and radiosity algorithms are covered thoroughly. (A basic knowledge of undergraduate calculus is assumed). The algorithms that have been developed to implement the radiosity method ranging from environment subdivision to final display are discussed. Successes and difficulties in implementing and using these algorithms are highlighted. Extensions to the basic radiosity method to include glossy surfaces, fog or smoke, and realistic light sources are also described. There are 16 pages of full colour images and over 100 illustrations to explain the development and show the results of the radiosity method. Results of applications of this new technology from a variety of fields are also included.Michael Cohen has worked in the area of realistic image synthesis since 1983 and was instrumental in the development of the radiosity method. He is currently an assistant professor of computer science at Princeton University. John Wallace is a software engineer at 3D/EYE, Inc., where he is the project leader for the development of Hewlett-Packard's ATRCore radiosity and ray tracing library. A chapter on the basic concepts of image synthesis is contributed by Patrick Hanrahan. He has worked on the topic of image synthesis at Pixar, where he was instrumental in the development of the Renderman software. He has also led research on the hierarchical methods at Princeton University, where he is an associate professor of computer science. All three authors have written numerous articles on radiosity that have appeared in the SIGGAPH proceedings and elsewhere. They have also taught the SIGGRAPH course on radiosity for 5 years.

  • Molecular Beam Epitaxy

    From Research to Mass Production
    • 1 Edición
    • Mohamed Henini
    • Inglés
    This multi-contributor handbook discusses Molecular Beam Epitaxy (MBE), an epitaxial deposition technique which involves laying down layers of materials with atomic thicknesses on to substrates. It summarizes MBE research and application in epitaxial growth with close discussion and a ‘how to’ on processing molecular or atomic beams that occur on a surface of a heated crystalline substrate in a vacuum.MBE has expanded in importance over the past thirty years (in terms of unique authors, papers and conferences) from a pure research domain into commercial applications (prototype device structures and more at the advanced research stage). MBE is important because it enables new device phenomena and facilitates the production of multiple layered structures with extremely fine dimensional and compositional control. The techniques can be deployed wherever precise thin-film devices with enhanced and unique properties for computing, optics or photonics are required. This book covers the advances made by MBE both in research and mass production of electronic and optoelectronic devices. It includes new semiconductor materials, new device structures which are commercially available, and many more which are at the advanced research stage.
