The readers involved in steel design and construction have appreciated the content of this informative title and have found it simply excellent. The publication was worked out by William Segui giving students and professionals all required knowledge that is covering the critical aspects of the steel design process with the particular emphasis made on the design steel members together with their connections.

Segui has designed this book in such manner that would allow the instructors to teach ASD, LRFD (or both), bearing in mind that there is only minor conceptual difference between them. He has made a very good job attempting to simplify the complex topics plus design procedures. This is definitely a best option for the persons who want to study the underlying theoretical principles plus the fundamental mechanics of the steel members.

All complicated topics have been clearly explained and the author made them quite easy to be understood even for the persons without any specific background or professional experience. Talking about clarity, there is no any other textbook that could be comparable to "Steel Design". We do recommend this volume to a broad audience since the explanations of various theoretical topics have been presented in a very accessible manner. The theoretical chapters are supplemented with many examples all of which, in turn, are thoroughly explained.

This informative volume contains all materials of the international workshop that was held in 1999 by the NRC (National Research Council) - they were collected in order to summarize the data and discuss the significance of the role of marine bio-technology in the prevention of the marine environment degradation together with its restoration and remediation. Each of the participants of that scientific event touched the current situation and tried to highlight the real research needs.

Among the important topics discussed by the speakers there were restoration of coral reefs, negative impact of heavy metals, possible strategies for prevention or at least inhibition of bio-film development, oil spill remediation etc. They have also tried to check the most important gaps in the technical knowledge possessed by the marine science community. These proceedings have been very carefully reviewed by the respected industry experts chosen for their remarkably diverse perspectives as well as prominent technical expertise as per with the established procedures.

It is definitely suggested that this set or technical documents is checked by every person involved or interested in the marine environment protection, because of the quality and up-to-dateness of information contained.

This publication by The Royal Institute of Naval Architects contains all materials of the Marine CFD - The Fourth International Conference of Marine Hydrodynamics held in 2005. It includes very interesting articles and researches by the world famous professionals. Among the topics addressed by the participants of the event there were dynamic mesh simulations of unsteady hydrodynamics of the ship, numerical simulation of yaw effect and free surface wave induced separation, scale effect influence on the propeller's hydrodynamic characteristics, prediction of the torque and thrust performance, various considerations on deviation in prediction of the torque, practical boundary element code development for hydrodynamic analysis, free-surface elevation around a moored vessel etc.

We all know that hydrodynamic aspects play a critical role in the quality of a vessel. The powering performance and hull resistance are considered dominant criteria for the ship hull form design. Moreover, vibration and noise that may seriously affect the passenger and crew comfort, often have the hydrodynamic origins and may be caused by stemming resulting from the operation of the propeller.

Warships - RINA International Conference - 2006. The reporters addressed following interesting topics in the course of that international conference - modeling maritime and warship survivability, operational experience with Sea Fighter FSF1, design issues concerning the high-speed adaptable littoral warfare, power and propulsion for the new generation of global combatant, survivability of the warships, tools to reduce vulnerability at the earliest stages of the ship design, multipurpose versus modularity, some affordable ways of protection of vessel systems against fragments and blast, and many more... the publication opens with the article dedicated to the new family of warships by VT Shipbuilding.

The significant increase in the costs over last decades for both new construction and upgrades/modifications and retaining in active service of the destroyers and frigates have resulted in the problems that are currently experienced by many Navy fleets when maintaining adequate ship hull numbers to perform various assigned tasks. The approach that is currently used today, implying production of the multi-purpose vessels may appear too costly to address imminent problems of fleets becoming lower and lower over the next years...

Marine International CFD Conference hosted by RINA in 2011. Some of the topics that have been discussed during that conference - Prediction of the ship wakes using the CFD, ship wake prediction, using these calculation methods for the improvement of predictions of ship manoeuvres, stern challenge, analysis of the craft resistance of the small crafts, trim wedge optimization, cavitating flow analysis in a tunnel thruster, design of the propulsion nozzles using auto-optimization routines, stabilizing fins design, OpenFOAM application, viscous flow computations, and many more...

The first one deals with the simulation of the self-propelled vessels with different computational flow dynamics methods, presented by the expert of the University of Genova. Today, the RANS solvers are considered a standard for and analysis of the flow measure and numerical prediction. Such method takes into consideration the hydrodynamic forces that act on the hull of the vessel, as well as the free surface effect.

It can be effectively used for the design/analysis of the ship propellers; note that the fact of the ship being self-propelled requires a very accurate solution of both above mentioned aspects that interact strongly. Unfortunately, the time and signal scales are difference for the hull and for the propeller...
