Most of the world’s energy still comes from fossil fuels, and there are still many strides being made in the efficiency and cost effectiveness of extracting these important and increasingly more elusive natural resources. This is only possible if the nature of the emergence, evolution, and parameter estimation of high grade reservoir rocks at great depths is known and a theory of their forecast is developed. Over 60 percent of world oil production is currently associated with carbonate reservoir rocks. The exploration, appraisal and development of these fields are significantly complicated by a number of factors. These factors include the structural complexity of the carbonate complexes, variability of the reservoir rock types and properties within a particular deposit, many unknowns in the evaluation of fracturing and its spatial variability, and the preservation of the reservoir rock qualities with depth. The main objective of most studies is discovering patterns in the reservoir rock property changes of carbonate deposits of different genesis, composition and age. A short list of the unsolved issues includes: the role of facies environment in the carbonate formation; the major geologic factors affecting the formation of high-capacity reservoir rocks and preservation of their properties; recommendations as to the use of the new techniques in studies of the structural parameters; and establishing a correlation between the major evaluation parameters. The focus of this volume is to show the scientific and engineering community a revolutionary process. The author perfected an earlier developed methodology in studies of the void space structure (Bagrintseva’s method, 1982). This methodology is based on carbonate rock saturation with luminophore and on special techniques in processing of photographs made under UV light. The luminophore technique was combined with the raster electron microscopy and its variation, the studies under the cathode luminescence regime. This combination enabled a more detailed study of the reservoir void space, the nonuniformity in the open fracture evolution, their morphology, length and variability of openness. Over recent years these techniques have found wide application. Useful for the veteran engineer or scientist and the student alike, this book is a must-have for any geologist, engineer, or student working in the field of upstream petroleum engineering.

The basic of the BPM technique in the frequency domain relies on treating the slowly varying envelope of the monochromatic electromagnetic field under paraxial propagation, thus allowing efficient numerical computation in terms of speed and allocated memory. In addition, the BPM based on finite differences is an easy way to implement robust and efficient computer codes. This book presents several approaches for treating the light: wide-angle, scalar approach, semivectorial treatment, and full vectorial treatment of the electromagnetic fields. Also, special topics in BPM cover the simulation of light propagation in anisotropic media, non-linear materials, electro-optic materials, and media with gain/losses, and describe how BPM can deal with strong index discontinuities or waveguide gratings, by introducing the bidirectional-BPM. BPM in the time domain is also described, and the book includes the powerful technique of finite difference time domain method, which fills the gap when the standard BPM is no longer applicable. Once the description of these numerical techniques have been detailed, the last chapter includes examples of passive, active and functional integrated photonic devices, such as waveguide reflectors, demultiplexers, polarization converters, electro-optic modulators, lasers or frequency converters. The book will help readers to understand several BPM approaches, to build their own codes, or to properly use the existing commercial software based on these numerical techniques.

In order to enable a better understanding of the key concepts of automation, this book develops the fundamental aspects of the field while also proposing numerous concrete exercises and their solutions. The theoretical approach that it presents fundamentally uses the state space and makes it possible to process general and complex systems in a simple way, involving several switches and sensors of different types. This approach requires the use of developed theoretical tools such as linear algebra, analysis and physics, generally taught in preparatory classes for specialist engineering courses.

An in-depth treatment of cutting-edge work being done internationally to develop new techniques in crop nutritional quality improvement Phytonutritional Improvement of Crops explores recent advances in biotechnological methods for the nutritional enrichment of food crops. Featuring contributions from an international group of experts in the field, it provides cutting-edge information on techniques of immense importance to academic, professional and commercial operations. World population is now estimated to be 7.5 billion people, with an annual growth rate of nearly 1.5%. Clearly, the need to enhance not only the quantity of food produced but its quality has never been greater, especially among less developed nations. Genetic manipulation offers the best prospect for achieving that goal. As many fruit crops provide proven health benefits, research efforts need to be focused on improving the nutritional qualities of fruits and vegetables through increased synthesis of lycopene and beta carotene, anthocyanins and some phenolics known to be strong antioxidants. Despite tremendous growth in the area occurring over the past several decades, the work has only just begun. This book represents an effort to address the urgent need to promote those efforts and to mobilise the tools of biotechnical and genetic engineering of the major food crops. Topics covered include: New applications of RNA-interference and virus induced gene silencing (VIGS) for nutritional genomics in crop plants Biotechnological techniques for enhancing carotenoid in crops and their implications for both human health and sustainable development Progress being made in the enrichment and metabolic profiling of diverse carotenoids in a range of fruit crops, including tomatoes, sweet potatoes and tropical fruits Biotechnologies for boosting the phytonutritional values of key crops, including grapes and sweet potatoes Recent progress in the development of transgenic rice engineered to massively accumulate flavonoids in-seed Phytonutritional Improvement of Crops is an important text/reference that belongs in all universities and research establishments where agriculture, horticulture, biological sciences, and food science and technology are studied, taught and applied.

This book comprehensively argues for more future benchmarking between nations. Since the initial food safety benchmarking report was published in 2008, the sharing of data and protocols among nations has dramatically increased. It was intended to identify and evaluate common elements among global food safety systems. More specifically, benchmarking identifies those countries that employ comparatively best practices to assess, manage, and communicate the risks related to the safety of food and their respective food systems. The overarching intent of this benchmarking assessment, however, is to stimulate exchange and discussion on food safety performance among nations.
