The issue will be useful to specialists in mechanical engineering and construction.

We are glad to present to our readers the 37th volume of International Journal of Engineering Research in Africa. This volume contains articles describing the research results in the fields of materials science, mechanical engineering, power distribution, construction materials and technologies, technological processes in the chemical production and environmental engineering, network engineering and supply chain. The articles will be useful for many engineers as well as for academic teachers and students majoring in these fields of engineering science.

The refined theory of beams, which takes into account both rotary inertia and shear deformation, was developed jointly by Timoshenko and Ehrenfest in the years 1911-1912. In over a century since the theory was first articulated, tens of thousands of studies have been performed utilizing this theory in various contexts. Likewise, the generalization of the Timoshenko-Ehrenfest beam theory to plates was given by Uflyand and Mindlin in the years 1948-1951.The importance of these theories stems from the fact that beams and plates are indispensable, and are often occurring elements of every civil, mechanical, ocean, and aerospace structure.Despite a long history and many papers, there is not a single book that summarizes these two celebrated theories. This book is dedicated to closing the existing gap within the literature. It also deals extensively with several controversial topics, namely those of priority, the so-called 'second spectrum' shear coefficient, and other issues, and shows vividly that the above beam and plate theories are unnecessarily overcomplicated.In the spirit of Einstein's dictum, 'Everything should be made as simple as possible but not simpler,' this book works to clarify both the Timoshenko-Ehrenfest beam and Uflyand-Mindlin plate theories, and seeks to articulate everything in the simplest possible language, including their numerous applications.This book is addressed to graduate students, practicing engineers, researchers in their early career, and active scientists who may want to have a different look at the above theories, as well as readers at all levels of their academic or scientific career who want to know the history of the subject. The Timoshenko-Ehrenfest Beam and Uflyand-Mindlin Plate Theories are the key reference works in the study of stocky beams and thick plates that should be given their due and remain important for generations to come, since classical Bernoulli-Euler beam and Kirchhoff-Love theories are applicable for slender beams and thin plates, respectively.Related Link(s)

We hope this collection will be useful and interesting for a wide range of engineers, scientists and students whose activity is related with creation and using of nanomaterials and nanotechnologies in the different branches of human activity.

Many approaches have been undertaken to mitigate global climate change, including the movement away from fossil fuels. Fossil Free Fuels: Trends in Renewable Energy examines several key topics, such as the utilization of biofuels as a sustainable renewable resource, recycling and untapped waste-to-energy products, and other carbon-neutral strategies in various industries, such as the transportation, construction, and manufacturing sectors. It provides recent updates on the latest technologies, modeling, design, and technical aspects, as well as several practical case studies. The current world energy scenario is examined and various solutions to larger environmental problems are outlined in terms of the shift to more alternative energy sources. Features: Minimizes technical jargon in a straightforward style for a wider audience Discusses sustainable options for different industries, such as the use of green materials in the construction sector, biofuels for transportation, and many more Includes numerous illustrations, tables, and figures to aid in understanding This book serves as a practical reference for engineers, researchers, environmental consultants working in renewable energy industries, and students.

Indigenous knowledge systems (IKS) are a combination of knowledge systems encompassing technology; social, economic, and philosophical learning; or educational, legal, and governance systems. The lack of documentation of these systems presents a problem as the knowledge is fading away over time. In response, it is essential that policies and strategies are undertaken to ensure that these systems are protected and sustained for generations to come. The Handbook of Research on Protecting and Managing Global Indigenous Knowledge Systems is a comprehensive reference source that works to preserve indigenous knowledge systems through research. Focusing on key concepts such as tools of indigenous knowledge management and African indigenous symbols, the book preserves and promotes indigenous knowledge through research and fills the void staff and students within the field of indigenous knowledge systems face with the current lack of research and resources. This book is ideal for university students, lecturers, researchers, academicians, policymakers, historians, sociologists, and anyone interested in the field of indigenous knowledge systems.
