Pheno-phospholipids and Lipo-phenolics: Novel Structured Antioxidants

by Mohamed Fawzy Ramadan

Natural phenolics are powerful bioactive compounds, but their use as antioxidant agents in lipid-based foodstuffs and cosmetics is limited due to their hydrophilic traits. A promising technique to overcome low solubility of phenolics is to increase their hydrophobicity by grafting with lipophilic moiety to form lipid-enriched phenolics (lipo-phenolics). Another way to enhance the amphiphilic traits of phenolics is by lipophilization with phospholipids in a suitable solvent to form phenolics-enriched phospholipids (pheno-phospholipids). Both functionalized phenolics (phenolipids) exhibit high bioavailability and antioxidative potential. Functional phenolics-enriched phospholipids (pheno-phospholipids) play an important role in enhancing the functional properties of both phenolic compounds and phospholipids in food for their use in nutrition and health. Phenolipids have also found applications on an industrial scale, likely due to low costs, the availability of starting material and safety. Recent advances in the field of lipophilization allow accessing molecules with high potency and targeted action covering a wide spectrum of bioactivities. Owing to their cost and availability, phenolipids find applications in niche sectors such as cosmetics and pharmaceutics as well as in the novel food. This book reports on the chemistry, preparation, and functionality of lipid-enriched phenolics (lipo-phenolics), broadening their applications in food, pharmaceuticals and cosmetics. The strategies of the lipophilization of phenolics, the effect of modification on the biological properties and potential applications of the resulting lipo-phenolics are reviewed. The text also discusses the preparation, physicochemical characteristics and functional properties of phenolipids and phytosomes, including the latest developments and their current industrial status.

Phenolic Resins: A Century of Progress

by Louis Pilato

With global capacity in excess of 5 million tons annually, phenolic resins are one of the leading thermosetting resins that are used in many diverse industries such as wood adhesives, fiberglass/mineral wool binder, molded materials for autos/electronic/electrical industries, brakes, abrasives, foam, coatings/adhesives, laminates, composites, metal castings/refractories, and rubber industry. These phenolic resin business areas are critical to the national economy and general welfare of emerging and developed nations. Although phenolic resins are barely noticed in these applications, it is difficult to imagine their absence since they are vital and not easily replaced by other polymeric materials due to favorable cost/performance characteristics of phenolic resins. In this new book these application areas are summarized and updated by global phenolic experts that are engaged daily in these activities. Further new technology and application areas of global technical activity are presented and include nanotechnology, updated phenolic resin chemistry, carbon fiber and long glass fiber reinforced molding materials, new analyses/testing, carbon foam, carbon/carbon brakes for autos, photo resists, new fiber reinforced systems, renewable raw materials, and recycling. It is anticipated that the new book will feature a global perspective of phenolic resins through the participation of international (North America, Europe and Asia) phenolic experts that was lacking in all previous books related to phenolic resins.

Phenomenological Creep Models of Composites and Nanomaterials: Deterministic and Probabilistic Approach

by Leo Razdolsky

The use of new engineering materials in the aerospace and space industry is usually governed by the need for enhancing the bearing capacity of structural elements and systems, improving the performance of specific applications, reducing structural weight and improving its cost-effectiveness. Crystalline composites and nanomaterials are used to design lightweight structural elements because such materials provide stiffness, strength and low density/weight. This book reviews the effect of high temperature creep on structural system response, and provides new phenomenological creep models (deterministic and probabilistic approach) of composites and nanomaterials. Certain criteria have been used in selecting the creep functions in order to describe a wide range of different behavior of materials. The experimental testing and evaluation of time variant creep in composite and nanomaterials is quite complex, expensive and, at times, time consuming. Therefore, the analytical analysis of creep properties and behavior of structural elements made of composite and nanocomposite materials subjected to severe thermal loadings conditions is of great practical importance. Composite elements and heterogeneous materials, from which they are made, make essential changes to the classical scheme for constructing the phenomenological creep model of composite elements, because it reflects the specificity of the composite material and manifests itself in the choice of two basic functions of the creep constitutive equation, namely memory and instantaneous modulus of elasticity functions. As such, the concepts and analytical techniques presented here are important. But the principal objective of this book is to demonstrate how nonlinear viscoelastic engineering creep theory can be incorporated into the general theory of mechanics of materials so that composite components can be designed and analyzed. The results are supported by step-by-step practical structural design examples and will be useful for structural engineers, code developers as well as material science researchers and university faculty. The phenomenological creep models presented in this book provide a usable engineering approximation for many applications in composite engineering.

Phenomics in Crop Plants: Trends, Options and Limitations

by Aditya Pratap Jitendra Kumar Shiv Kumar

Identification of desirable genotypes with traits of interest is discernible for making genetic improvement of crop plants. In this direction, screening of a large number of germplasm for desirable traits and transfer of identified traits into agronomic backgrounds through recombination breeding is the common breeding approach. Although visual screening is easier for qualitative traits, its use is not much effective for quantitative traits and also for those, which are difficult to score visually. Therefore, it is imperative to phenotype the germplasm accessions and breeding materials precisely using high throughput phenomics tools for challenging and complex traits under natural, controlled and harsh environmental conditions. Realizing the importance of phenotyping data towards identification and utilization of a germplasm as donors, global scientific community has exerted increased focus on advancing phenomics in crop plants leading to development of a number of techniques and methodologies for screening of agronomic, physiological, and biochemical traits. These technologies have now become much advanced and entered the era of digital science. This book provides exhaustive information on various aspects related to phenotyping of crop plants and offers a most comprehensive reference on the developments made in traditional and high throughput phenotyping of agricultural crops.

Phenotropic Interaction: Improving Interfaces with Computing with Words and Perceptions (Fuzzy Management Methods)

by Moreno Colombo

Successful interaction between humans and artificial systems allows for combining the advantages of all actors in solving problems. However, interaction is often demanding for people, as it builds on artificial concepts, such as strict protocols.This book presents the new paradigm of 'phenotropic' interaction, which aims to improve the naturalness of the interaction thanks to bio-inspired approaches. These include methods for understanding and reasoning with human perceptions expressed as natural language, fundamental to support the artificial system to better understand people's real desires and needs. Methods for improving the theories of computing with words and perceptions are developed in this book and applied to concrete use cases in prototypes enhancing the exchange of information with virtual assistants and smart city ecosystems. The presented use cases serve not only as examples of the application of the phenotropic interaction principles but also to verify their effective impact on communication.

Philosophical Explorations of the Legacy of Alan Turing: Turing 100 (Boston Studies in the Philosophy and History of Science #324)

by Alisa Bokulich Juliet Floyd

This volume presents an historical and philosophical revisiting of the foundational character of Turing's conceptual contributions and assesses the impact of the work of Alan Turing on the history and philosophy of science. Written by experts from a variety of disciplines, the book draws out the continuing significance of Turing's work. The centennial of Turing's birth in 2012 led to the highly celebrated "Alan Turing Year", which stimulated a world-wide cooperative, interdisciplinary revisiting of his life and work. Turing is widely regarded as one of the most important scientists of the twentieth century: He is the father of artificial intelligence, resolver of Hilbert's famous Entscheidungsproblem, and a code breaker who helped solve the Enigma code. His work revolutionized the very architecture of science by way of the results he obtained in logic, probability and recursion theory, morphogenesis, the foundations of cognitive psychology, mathematics, and cryptography. Many of Turing's breakthroughs were stimulated by his deep reflections on fundamental philosophical issues. Hence it is fitting that there be a volume dedicated to the philosophical impact of his work. One important strand of Turing's work is his analysis of the concept of computability, which has unquestionably come to play a central conceptual role in nearly every branch of knowledge and engineering.

Philosophical, Logical and Scientific Perspectives in Engineering

by Zekâi Şen

This book highlights and explains the significance of philosophical, logical, and scientific principles for engineering education/training and engineering works. In so doing, it aims to help to rectify the neglect of philosophy and logic in current education and training programs, which emphasize analytical and numerical methods at the expense of the innovative practical and creative abilities so important for engineering in the past. Individual chapters examine the relation of philosophy, logic, and science to engineering, drawing attention to, for example, the significance of ethics, the relevance of the philosophy of science, and the increasing importance of application of fuzzy logic to engineering. Modeling principles and philosophy in engineering are discussed, and the impact of different education systems, examined. Too often engineers have become reliant on readily available formulations and software; this book offers an antidote, promoting the recognition of artistic and humanitarian aspects and their integration in engineering works.
