Hepatobiliary medicine has seen major recent scientific advances in viral hepatitis, haemochromatosis and autoimmune liver/disease helped by imaging advances in MRI and CT. This volume of some 200 cases by an internationally renowned author team, covers the whole spectrum of liver disease, focusing on the clinical photos, imaging, charts and graphs. The problem-oriented, randomized self-assessment format, lends itself to revision and continuing professional development. The book will appeal particularly to young doctors preparing for membership and board examinations.

There is now an awareness within the industry, particularly as oil companies direct considerable resources towards developing diverless production systems, that a fully integrated approach to equipment design and intervention is necessary to achieve an acceptable system. The requirement for an integrated approach to equipment design and intervention is applicable not only to diverless depths but to all subsea structures, equipment and intervention techniques in whatever depth. Fortunately the inherent dexterity of the diver does not impact so severely on design as other intervention techniques. However the benefits of an integrated approach are still applicable and the use of such simple "diver aids" as cutting guides and subsea markings installed prior to the installation of jackets and subsea equipment can have a significant impact on the cost of intervention. This paper examines the requirements and limitations in designing subsea equipment for Remotely Operated Vehicle (ROV) intervention. For the oil company embarking on the development of a diverless production system, be it totally diverless because of the envisaged water depth or primarily diverless with the possibility of diver back up, the intervention techniques adopted will strongly influence the final system design. The necessity to undertake an extensive development programme to produce the optimum intervention system is very costly, requires long lead times and comprehensive testing particularly where novel solutions are adopted. It is a daunting prospect for even the most progressive of oil companies.

Digital Photography DSLR So you want to learn about digital photography. 'Digital Photography - DSLR' has been is written for those who want to learn digital photography. It covers all of the basic digital photography techniques. When you are learning digital photography it is vital that you understand the digital photography basics so that even with an entry level DSLR you can produce sound pictures, both technically and creatively. For the purpose of this book, which is basically a guide to digital photography, I will be using images shot with my Canon 350D. Some were taken with the 18 - 55mm kit lens and some with the upgraded Canon EFS 17 - 85mm, I chose to use my old 350D to simply demonstrate that you do not need to own the most expensive kit to be able to take great pictures. Through the use of both lenses I cover the majority of the basic digital photography techniques, and these techniques explained here apply to all makes of camera. It is only when you get to the prosumer level that things need to be explained on an individual camera basis. When I started taking photographs back in the days of film there were certain basics that had to be understood in order to produce a good photograph and the same basics apply to the digital photography cameras of today. No matter how clever they get the real photographer will always want to take creative control into their own hands and so there is an inherent need to understand exposure, the histogram, aperture, shutter speeds, ISO, depth of field, the relationship between shutter speed, exposure and aperture, focus, focal plane in relation to aperture and of course how to frame the shot. The purpose of this book is not to focus (excuse the pun) on any one specific genre of photography, such as portrait or landscape photography, but to give a solid grounding in the basics required to produce a good picture. Below is a list of the subjects covered however other information will no doubt creep in as I get over enthusiastic about certain subjects. To put your mind at ease a lot of what I am about to explain did not come easy to me and I totally understand some of the frustration you are experiencing or will experience in the future as you learn the art of photography. I believe it is important to remember one thing above all else and that is: 'The word "photography" comes from two Greek words, photo- meaning light and graph - meaning draw', so you are literally 'Drawing with Light'. Personally I think that is rather beautiful and when I get frustrated it helps me to remember that photography is not just a mechanical process. I wish you the best with your endeavours and I hope this book goes some small way in helping you to achieve your goals with your DSLR. Roger Chapman

This book provides a definitive history of the U.S. Army Rangers that details the origins and development, combat philosophy, and key engagements of America's elite fighting force. The U.S. Army Rangers: Forging a Special Operations Force details the origins and development, combat philosophy, and key engagements of America's elite fighting force. Structured topically, the book allows for a chronological review of the history of the Ranger from the 17th century to the present day, with special attention paid to the establishment of the 1st Ranger Battalion in the post-Vietnam era-the origins of the elite fighting force that exists today. This book is replete with information garnered from dozens of interviews with the individuals who created the initial Ranger Force. By integrating the words and first-hand accounts of these founding fathers, the work offers insights unavailable elsewhere. Additionally, the author delves into the unique psyche of the soldiers who volunteer for-and are accepted into the ranks of-the "Rangers." * Explores the mindsets and the challenges facing the individuals who were involved in developing America's premier fighting force * Provides an unprecedented firsthand account of the formation of the Ranger Regiment that exists today * Describes the soldier's experience-and the Army itself-at the end of the conscript Vietnam-era Army, a pivotal time in the development of American military forces * Presents colorful vignettes taken from current conflicts in Iraq and Afghanistan * Provides real-world examples of what it is like to be a modern day Ranger that allow readers to understand the Ranger psyche
