One of the principal goals declared by the author of this volume was to establish the connection between the mechanical hardness numbers and the physics of the chemical bonds in quantitative and simple ways. In the past, this has not been achieved in the effective manner as the commonly involved atomic processes have not been properly an fully identified.

Though it is still true for the cases of the complex atomic structures, the author of the title believes that the relatively simple prototype cases are duly understood today. It should be taken into consideration, however, that the associated mechanisms change with the types of the chemical bonding. And no universal chemical mechanism exists there to determine the mechanical hardness. The author has made an attempt to develop the proper understanding of the plastic deformation and hardness; this is definitely not a straightforward task as the literature sources covering this subject is still partly confused.

The chapters of the volume cover the indentation and plastic deformation, covalent semiconductors and chemical bonding, transition metals, ionic and molecular crystals, glasses and polymers, chemical and hot hardness, simple alloys and metals, inter-metallic compounds, hard metals and "superhard" materials, actually everything one will require to be aware of...

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.

Today, the role of the chronobiology is in proper understanding of the time base of both marine animals and plants, along with their behavior, physiology and ecology, is being deservedly recognized and this recognition is constantly increasing. It shall be noted, however, that the major portion of all efforts that have been made by the scientists so far was focusing on the seasonal/daily rhythmicity that is commonly associated with the solar periodicity.

In his publication the author, Ernest Naylor, who is the expert in his field, has made a brilliant attempt to describe how exactly the marine organisms ranging from the single cells and up to the vertebrates, and living in estuaries, as well as in the open-ocean and on the sea shores, evolved the bio-clockwork together with the mechanisms of synchronization controlling their rhythmic processes and also their navigational behavior.

The author has also applied a hypo-testing and experimental approach and, as a result, this volume could be used by the any-level students of marine science, marine biology and ecology, oceanography, behavior of the animals and all other biological sciences; it will also be very useful when used as an into for researchers, such as the biologists, biochemists and physiologists, making their first steps in chronobiology.

There are a great variety of ships at sea today whose many technical specifications of engineering installations. The one thing that is common to all of them is that they all require the use of water - one way or another. It may be used for steam production or engine cooling, or simply for consumption by the officers and crew. In fact, water will be used on board in considerable quantities.

Fortunately, there is always plenty of it available in the form of a sea water; they can pump it and use it straight away for washing the deck, for example. But if you try and use this water in a boiler, or for cooling your main engine, in a few days catastrophe will hit the ship - the boiler could blow up or the main engine get damaged. This is because sea water is contaminated by dissolved and dispensed solids, namely sodium chloride, calcium carbonate, magnesium carbonate and calcium sulphate.

These form deposits which can cause overheating and mechanical breakdown, making it unsuitable for use in boilers and in engine cooling systems, just like it is unsuitable for drinking by human being. that is why the cleaning and treatment of water on board the vessel is so important for the ship's efficient operation - and that is where chemical treatment plays a vital role by preventing internal corrosion and scaling formation...

Today, we are introducing the latest, fourth edition of the volume that has been significantly updated using the very recent literature. The content of the book remains basing on graduate/undergraduate university courses which the author has taught for the past forty-five years. Over the past decade numerous new and interesting large-scale oceanographic programmes have been introduced, including the GDMP, standing for the geochemical trace metal program, and climate variability program.

This program is mainly intended to contribute in proper understanding the bio-geochemical cycles of trace elements in the water. The basic studies have already demonstrated the input of both Fe and Pb from the hydrothermal vents and the redox behavior of metals in waters with low content of oxygen. The above mentioned studies are expected to produce lots of valuable information related to the biogeochemistry. The constantly increasing content of the carbon dioxide in the atmosphere, that is resulting from the burning of various fossil fuels is continuing to affect the atmosphere as well as the oceans. The temperature of the surface waters is also increasing and is consequently causing stratification in the oceans.

This all has already led to numerous areas of low oxygen in coastal ocean waters. Each year many oceanographers are doing their best to duly contribute to the rapidly expanding technical knowledge of the oceans. The author has made an excellent attempt to build and update this intro to Chemical Oceanography with new understanding and modern concepts...
