Nanofibres Friend Or Foe

This book is a printed edition of the Special Issue "Nanofibres: Friend or Foe?" that was published in Fibers

Nanofibers, particularly those of a carbonaceous content, have received increased interest in the past two decades due to their outstanding physico-chemical characteristics and their possibility to form and contribute towards a plethora of potentially advantageous materials for consumer, industrial and medical applications. Despite this, and together with the numerous research studies and published articles that have sought to investigate these aspects, the potential impact of CNTs is still not understood. Whether or not nanofibers may be able to provide a sophisticated alternative to conventional materials is still debatable, whilst their effects upon both environmental and human health are highly equivocal. How nanofibers are conceived can determine how they may interact with different environments, such as the human body. Understanding each key step of the synthesis and production of nanofibers to their use within potential applications is therefore essential in gaining an insight into how they may be perceived by any biological system and environment. Thus, obtaining such information will enable all scientific communities to begin to realize the potential advantages posed by nanofibers. The aim of this Special Issue therefore, was to provide a collective overview of nanofibers; 'from synthesis to application'. The Issue particularly focuses upon carbon-based nanofibers, but also highlights alternative nanofiber types. Emphasis is given holistically, with articles discussing the production routes of nanofibers, their plight during their life-cycle (origin to applied form and effects over time), as well as how nanofibers could either incite conflict, or provide aid to human and environmental health

Nano- and Nanohybrid Fungicides: Novel Applications in Plant Pathology addresses nanofungicides and the opportunities that nano-agrochemicals can provide. Organized into three parts, this book addresses the synthesis and formulation of nanofungicides and nanohybrid fungicides, as well as their sensing, degradation, and commercialization. Furthermore, the book assesses the potential hazards and safety of nanofungicdes for agroecosytems, in addition to startup, patents, regulatory concerns, and prospects. Plant scientists, plant pathologist, agriculture and food scientists, and professionals and students working in related fields will all benefit from this timely resource. Explains the synthesis or biosynthesis of nanofungicides Determines the active ingredients of nanofungicides Describes the applications of nanofungicides in plant disease control and crop protection Explores the mechanisms of antifungal activity

This updated 6th Edition is fully aligned with the most current DSM-5 and Occupational Therapy Practice Framework, 4th Edition, and adds new chapters reflecting recent advances in the management of infectious diseases, general deconditioning, musculoskeletal pain, amputations, and sickle cell anemia. Each chapter follows a consistent format, presenting an opening case followed by descriptions and definitions, etiology, incidence and prevalence, signs and symptoms, diagnosis, course and prognosis, medical/surgical management, impact on occupational performance, and two case illustrations. Rounded out with robust instructor resources and new full-color imagery, this bestselling resource is an essential tool for today’s occupational therapy and occupational therapy assistant students.

Phenolic compounds are secondary metabolites found in legumes, grains, fruits, algae, leaves and many other dietary sources. However, the abundance and differences in chemical structure, solubility, toxicological safety and, therefore, bioactivity and functional effects in humans. This book covers the basic chemical composition and structure of phenolic compounds and focus on their technological applications in food models and products: nondairy and dairy beverages, bakery, and meat-based foods. Additionally, food preservation aspects, including the effects of polyphenols additions on the product’s shelf-life, processing and recovery of polyphenols from plant materials, antioxidant and antiproliferative aspects of polyphenol-rich extracts are considered and holistically debated. Toxicological safety of polyphenols in foods is explained and discussed Application of polyphenols in dairy and nondairy foods is discussed Effects of polyphenols on food preservation/shelf-life are explained

Polyphenols are a heterogeneous group of bioactive compounds mainly found in plant-based foods. Numerous clinical and epidemiological studies have led to the result that polyphenol intake may protect against chronic diseases such as cardiovascular and neurodegenerative diseases, cancer, or type 2 diabetes, to name some. Polyphenol intake estimation can be obtained through food frequency questionnaires and nutritional biomarkers, both having their own advantages and disadvantages. Although the association between these bioactive compounds and health seems irrefutable, many questions remain still unanswered. For instance, more studies are needed to identify possible interactions and effect-modulating variables, such as smoking habit, body mass index, sex, alcohol, hormones, other foods, etc. Moreover, intestinal microbiota seems to play an important role in the metabolism of polyphenols, but it is still unclear how.

Human Orthopaedic Biomechanics: Fundamentals, Devices and Applications covers a wide range of biomechanical topics and fields, ranging from theoretical issues, mechanobiology, design of implants, joint biomechanics, regulatory issues and practical applications. The book teaches the fundamentals of physiological loading and constraint conditions at various parts of the musculoskeletal system. It is an ideal resource for teaching and education in courses on orthopedic biomechanics, and for engineering students engaged in these courses. In addition, all bioengineers who have an interest in orthopedic biomechanics will find this title useful as a reference, particularly early career researchers and industry professionals. Finally, any orthopedic surgeons looking to deepen their knowledge of biomechanical aspects will benefit from the accessible writing style in this title. Covers theoretical aspects (mechanics, stress analysis, constitutive laws for the various musculoskeletal tissues and mechanobiology) Presents components of different regulatory aspects, failure analysis, post-marketing and clinical trials Includes state-of-the-art methods used in orthopedic biomechanics and in designing orthopedic implants (experimental methods, finite element and rigid-body models, gait and fluoroscopic analysis, radiological measurements)
