Obviously, water is the most fundamental resource considered the basis of all life on our planet, and this resource is becoming increasingly important issue and potential source of conflict in today's world. The present fascinating volume setting out numerous ingenious methods used by the ancient human societies to gather, transport and store water, is a very timely book taking into account a profligacy and overextraction threatening the existence of the watercourses and aquifers that for millennia have been supplying people's needs for the water.

The book is intended to provide readers with a general overview of the water technologies established by some of the ancient human civilizations. No publication on water technologies of the ancient times might be considered complete without discussions of the engineering developments of the Greeks and Romans, and these have been covered in the present volume together with the examination of how American societies of that historical period accommodated their water requests.

The text of the book is really wide-ranging and offering some practical and effective technical solutions to the crisis taking place in today's water supply. Readers will find valuable insights made by the author into the ancient water technologies which underpin most of the contemporary practices of water engineering and management.

The publication is aimed at non-specialists using the electric motors/drives, and it was released to fill the gap that is there between the theory-based academic books and a bit more prosaic 'handbooks' providing useful detail but giving little to not opportunity for the real understanding and development of insight. It addresses nearly all modern types of motors/drives, including both conventional and brushless direct current induction motors plus servo drives.

The present third edition of the book includes numerous examples and diagrams; moreover, there are so many new topics covering the material that has not been included in the second release of the publication. The authors used a minimum of mathematics in order to make the book easy to use and make the material easy to understand to all groups of readers. The material and data provided in the book are up-to-date and will be useful to OEM designers, electricians, users of the electrical equipment, maintenance and repair personnel who are involved in making decisions.

Anyone who spends some time on this book will get a truly comprehensive understanding of the subject. We would say that it is an excellent technical book and maybe even one of the best books on electrical motors and drives available today. Though the material has been presented in a very understandable manner, the publication retains its technical soundness.

The volume is providing a truly comprehensive coverage of both strain and stress analysis of the circular cylinders as well as of pressure vessels, and this is one of the most important classic topics of the theory and methodology of machine design. Most of the other books available today, are offering only a partial coverage of this subject and in the majority of cases they only consider the stress analysis in the elastic field; in the meantime, this book enlarges the design area and analyzes the processes occurring at pressures stressing the materials beyond their yield points and at thermal loads giving rise to creep.

This work by Vincenzo Vullo, who is professor at the University of Rome, teaching the mechanical design discipline, considers not only traditional but also advanced topics, ensuring that it will be useful to the machine design engineers and researches in this field. The relations that have been provided by the author, re intended to serve as a sound foundation for the design of those products that are considered safe and sophisticated from the technological point of view, and also complying with the requirements of the recognized technical codes and standards, plus for the developments of various innovative applications.

We are introducing maybe the most popular and very highly respected publications on mechanics. This world recognized publication is mainly focusing on the development of the correct understanding of the fundamental principles rather than just addressing the specific methodologies.

The author of this volume, Irving Shames, has covered all basic principles instead of applying the "cookbook" approach and his also did his best trying to make this book more readable. This release of the volume is the latest available one and it includes more than five hundred completely new technical problems that have all been checked for accuracy by the author, very carefully and rigorously.

The topics of the book related to statics are covering the basics of mechanics, vector algebra and quantities, equilibrium equations, some introductory information on structural mechanics, and all other related topics, while the part of the book dedicated to the dynamics addresses particle dynamics, kinematics of rigid bodies including plane motion, dynamics relating to same, vibration matters etc.

The text presented by the author is deservedly considered as invaluable source of technical reference for students of mechanical engineering; they way material is presented makes the volume so reader-friendly and numerous examples allow the students understand the theory much easier.

The Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection addressed the problem of littering the marine environment by plastic and microplastics for decades. From the beginning, they focused mainly on microplastics, considering them an emerging concern, which would lead to the development of a scoping paper.

The international workshop held back in 2010 by GESAMP, centered on the microplastic particles as a vector for transporting persistent, bio-accumulating, and toxic substances in the ocean. The subject workshop was the first to convene representatives from the all interested parties, including but not limited to the chemicals industry, academia, policymakers, and intergovernmental organizations.

One of the conclusions made was that further evaluation of the potential impacts of microplastics was necessary. That led to the establishment of the GESAMP Working Group 40 (WG40) in 2012 to investigate the sources, fate, and effects of microplastics in the marine environment.

The fleet submarine Shark wallowed heavily in an oily following sea. It was a moonless night with no breeze. The six men on bridge watch searched the dark horizon more intently than usual. Shark lay astride the Japanese convoy routes from the Marianas to Japan—a busy spot in the northern reaches of the Bonin Islands—and the SJ surface-search radar was temporarily out of commission.

At 0134, Willie Bonsel, one of three lookouts who were standing on a platform in the periscope shears, broke the silence on the bridge. "Smoke on the horizon. Zero-three-zero." The contact had apparently not fazed Fireman Bonsel, who was noted for his taciturnity, but the other five men on the bridge were electrified. Especially the quartermaster, Jack Childress, fresh out of sub school and making his first war patrol.

When he swung his 7-by-50 binoculars to the horizon off the starboard bow, his hands trembled so badly he could not focus the lens. The officer of the deck, Jim Bell, a reserve lieutenant, junior grade, who was Shark's communications officer, riveted his binoculars on the horizon and spoke quietly but authoritatively into the intercom to the conning tower immediately below: "Report to the captain. Smoke on the horizon. Zero-three-zero. Come right to two-five-oh. Secure the battery charge. Put all four main engines on the line. All ahead full."...

In the last years, the increasing number of the complex problems has required much more technical knowledge  be possessed by the engineers to be able to address and mitigate them. Such problems include but are not limited to the design of various engineering systems and subsystems, their design/re-design and interaction of other systems.

The present publication by Atila Ertas presents readers the fundamental concepts of the mechanical engineering in the context of the design process, providing all of them, and especially non-mechanical engineers, with the required knowledge and understanding of the most important mechanical aspects of a project, thus making the collaboration in transdisciplinary teams a bit easier. The author as managed to combine in a single volume the statics and dynamics, together with the vibration and material strength, offering a practical reference for design.

The book starts with the comprehensive overview of the PtD, standing for the "prevention through design", giving an idea of the occupational HSE needs and presents the condensed introduction to the engineering statics and dynamics, failure theories and various dynamic loadings.

The content also includes numerous real-life examples of the design and analysis together with the practical applications demonstrating how exactly the transdisciplinary knowledge could be applied in practice. The book shall be suitable for the students willing to understand the basics of engineering mechanics, as well as the professionals in the industry.
