The articles will be useful for many engineers as well as for academic teachers and students majoring in the mentioned fields of engineering science.

The 49th volume of "International Journal of Engineering Research in Africa" contains peer-reviewed manuscripts reflecting the research results in the fields of materials science, applied mechanics and mechanical engineering. Such issues as sensitivity analysis, renewable energy, pressure gradient, multiphase flow, power quality are raised in the volume. The presented scientific articles can be appreciated by the majority of engineers, academic teachers and students majoring in the fields of engineering science.

In this current 49th volume of the journal "Journal of Nano Research" we present to readers the collection of peer-reviewed papers by results of scientific and engineering researches from field of nanomaterials and applied nanotechnologies. 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.

This book presents a holistic view on localized energy transition while addressing current challenges associated with the production of biofuels, introducing new materials to produce solar photovoltaic (PV) panels, and digital systems for sustainable energy monitoring on a small scale, carbon capture, and sequestration. Also, each chapter of the book addresses specific aspects of the renewable and sustainable energy space while focusing more on energy improvement and storage technologies that are practical focused. Features: Offers useful information on new forms of renewable energy generation with reference to Industry 4.0. Illustrates practical approaches to energy transition. Provides guidance on renewable energy sources and energy storage systems. Discusses the application of the Fourth Industrial Revolution (4IR)-related approaches to emerging energy storage technologies. Includes studies that reveal approaches to realizing productivity, profitability, and increased return on investment (ROI). This book is aimed at graduate students and researchers in mechanical, chemical, and mechatronics engineering and renewable energy systems.

Humanities studies on the Arabian Peninsular including anthropology, archaeology, architecture, art, epigraphy, ethnography, history, language, linguistics, literature, numismatics, theology, and more, from the earliest times to the present day or, in the fields of political and social history, to around the end of the Ottoman Empire.

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)

​Engineering and infrastructure assets maintain the lifeline of economies. It is, therefore, critical to manage these assets in such a way that they provide a consistent level of service throughout their lifecycle. Management of asset lifecycle, however, is information intensive and utilises a plethora of information systems. The role of theses systems in asset management is much more profound. It extends beyond the organizational boundaries and addresses business relationships with external stakeholders to deliver enhanced level of business outcomes. In doing so information systems are not only required to translate business strategic considerations into action, but are also expected to produce learnings and feedback that informs business strategy and aids in strategic reorientation.
