The main aim of Ashley Waite, the practicing engineer and author of this excellent and very useful volume, was to provide all other practicing engineers with the source of information that would help them to understand the fundamental working principles of sonars and also to let them develop the formulas and so-called rules of thumb for the design and performance analysis of subject equipment.

Having a remarkably long professional experience in design and operation of sonars, the author has managed to use this knowledge providing a good practical guidance and working solutions to the various problems most commonly encountered by the technicians and engineers involved in design and operation of the sonars as well as in the performance analysis. The content is arranged in three main parts covering the parameters of the equipment, sound propagation through the sea water and practical sonar systems.

The book is covering all important aspects of sonars and contains numerous useful working examples. The readers are not expected to have any serious knowledge of sonars because the way of explanation is very clear and easily understandable even to the beginners, with no math or physics background required. The end-chapter exercises provided with the correct solutions have been included for the self-assessment and tracking of the training process. The book will be an excellent addition to every engineer's library.

This volume has been released with the intention of it's editor, J. Nihoul, who prepared it trying to compile in a single volume, all proceedings of the XIX International Colloquium on the problems of ocean hydrodynamics. The program of the subject conference was focusing on the relationships existing there between large- and small-scale features, together with the associated processes and transports.

The volume presents the valuable articles covering the different methods of parameterization of small-scale turbulent mixing as applied to the numerical ocean models, the presentation of subject papers has been specifically encouraged by the editor, and the application of the subject approach has finally resulted in significant portion of the articles presented during the Colloquium, dealing with the current problems of parameterization. Note that some of the presented docs demonstrated the direct results obtained during the modeling.

The volume is well reflecting the above stated proportion and emphasizes the whole importance of the researches oh small-scale turbulence for the practical applications, such as the forecasting and ocean modeling. The book will be equally useful, practical and informative for persons willing to be in the loop of any latest happenings in the subject field.​

A course in spoken English language may be presented in either "what to say" or "how to say" form. As a rule, the first of the forms usually focuses on English conversation and teaches how to ask questions, get things done, make requests, express greetings, apologies, farewells, thanks, etc. And the "how to say" form of course deals mostly with English pronunciation and aims to teach the reader the proper pronunciation of English words, phrases and sentences.

Most of the books on spoken English belong to one or the other of these two kinds. This publication, however, deals with spoken English language in both aspects at the same time. This book consists of twenty units, with each of them beginning with a conversation or dialogue - they are to be read carefully by the students before proceeding to the main material of the unit. In fact, this publication is mainly addressed to the students of English who are familiar with the general structure of this language but experience difficulties with communication, and speaking in particular.

No other pre-qualification is required. The aim of this volume is to improve the pronunciation of the learners as well as their colloquial usage making it a bit easier for them to communicate effectively.

The IMO publication which does not require any special introduction. The most important and basic international convention. The must-have document on board any ship and in the office of any shipping company; the necessary one for the marine surveyors, port state control inspectors, and even students - i.e. anyone whose day-to-day activities are related to the safety of human life at sea.

Traditionally, the content of the document is divided into twelve major chapters. The first chapter provides the general provisions. The second chapter has been divided in two parts addressing the construction of the ship, namely structure of the ship, subdivision of the hull, stability of the vessel, ship machinery and electrical installations on board. The next three chapters deal with the lifesaving appliances, radiocommunications and navigational safety. Then, there come two chapters addressing the carriage of cargoes and dangerous goods in particular.

There is one separate chapter on nuclear ships.
