Nanotechnology has shown great potential to alleviate increasing pressure to meet food needs for our increasing human population, Novel agricultural innovations are required to enhance the health of edible crops and per unit area yield without impacting the associated environment in a negative way. Recent advancements in nanotechnology-based agricultural solutions have proven to help overcome the problems in agriculture that are associated with run-off of essential fertilizers from agricultural soils, low nutrient accumulation by crops, as well as to control insects, pests, and seasonal biotic factors, treatment of wastewater used for irrigation, plant uptake of xenobiotics (heavy metals, pesticides, industrial chemicals, drugs, and so on) that may be present in contaminated soils. Additionally, the consumption of such food crops may result in malnourishment and plant-mediated transfer of toxic substances among humans especially in underprivileged and rural populations. Agents to stimulate plant growth include various types of nanomaterials such as carbon nanotubes, metal, and metal-oxide nanoparticles. Applications of particular nutrients or elements in crop plants can be shown to aid human nourishment (either by directly inducing its uptake or indirectly through enhancing the intracellular levels of other associated elements that ultimately boost the synthesis of the desired nutrient in plants). It is also important to consider the competence and fate of nanomaterials in soil ecosystems. The entry route of nanomaterials into the environment includes both natural and anthropogenic sources. In order to achieve sustainable and safe use of nanotechnological products in agriculture, similar environmental conditions must be simulated on lab scale with the careful selection of organisms related to agriculture. Thus, emphasis should be placed on the judicial use of nano-enabled products without compromising the sustainability of the environment and human health. This comprehensive book highlights recent field research as well as contributions from academicians in the lab. This book addresses the major aspects related to nanotechnology, biofortification of crops, and human and environmental health.

This book offers an in-depth verification of numerical solutions for differential equations modeling heat transfer phenomena, where the smoothed particle hydrodynamics (SPH) method is used to discretize the mathematical models. Techniques described in this book aim to speed up the convergence of numerical solutions and increase their accuracy by significantly reducing the discretization error.In their quest, the authors shed light on new sources of numerical error that are specific to the SPH method and, through them, they identify the characteristics of the solutions influenced by such errors. The accuracy of numerical solutions is also improved with the application of advanced tools like the repeated Richardson extrapolation (RRE) in quadruple precision, which was adapted to consider fixed or moving particles. The book finishes with the conclusion that the qualitative and quantitative verification of numerical solutions through coherence tests andmetrics are currently a methodology of excellence to treat computational heat transfer problems.Mathematicians in applied fields and engineers modelling and solving real physical phenomena can greatly benefit from this work, as well as any reader interested in numerical methods for differential equations.

This book in the advanced structured materials series provides first an introduction to the mircomechanics of fiber-reinforced laminae, which deals with the prediction of the macroscopic mechanical lamina properties based on the mechanical properties of the constituents, i.e., fibers and matrix. Composite materials, especially fiber-reinforced composites, are gaining increasing importance since they can overcome the limits of many structures based on classical metals. Particularly, the combination of a matrix with fibers provides far better properties than the constituents alone. Despite their importance, many engineering degree programs do not treat the mechanical behavior of this class of advanced structured materials in detail, at least on the bachelor¿s degree level. Thus, some engineers are not able to thoroughly apply and introduce these modern engineering materials in their design process. The second part of this book provides a systematic and thorough introduction to the classical laminate theory based on the theory for plane elasticity elements and classical (shear-rigid) plate elements. The focus is on unidirectional lamina which can be described based on orthotropic constitutive equations and their composition to layered laminates. In addition to the elastic behavior, failure is investigated based on the maximum stress, maximum strain, Tsai-Hill, and the Tsai-Wu criteria. The introduced classical laminate theory provides a simplified stress analysis, and a subsequent failure analysis, without the solution of the system of coupled differential equations for the unknown displacements in the three coordinate directions. The book concludes with a short introduction to a calculation program, the so-called Composite Laminate Analysis Tool (CLAT), which allows the application of the classical laminate based on a sophisticated Python script.

This book provides insights into microfiber pollution in textile industries that would help researchers and professionals to work from the textile point of view to mitigate the problem, and create a green sustainable future. Microplastic pollution has received great importance due to its adverse environmental and health impact. Microplastic particles are found to contaminate the ecosystem. Research has reported microplastics on seashores, in deep seas, freshwater systems including rivers and lakes, and most importantly in the air. Various land-based and water-based organisms are also contaminated with microplastics. The most serious issue is when these particles are found in the food chain and air which can reach the human system. It has been estimated that human beings can intake up to 1,21,000 microplastic particles in a year through food and inhalation. Being one of the most polluting industries, the contribution of Textile industries in microplastic pollution is extremely higher (around 35%). This book addresses the issue of microfiber/microplastic pollution cause by various techniques including home laundry and the ways to alleviate it.
