Andrew D. Duckworth Book order

In railway modelling, getting the technical components correct is essential for a realistic-looking layout but, unfortunately, these often present the biggest challenges for the hobbyist. Using his own experience as a railway modeller and electronics engineer, Andrew Duckworth provides a guide suitable for all railway modellers, from beginners to the more experienced. With instructions on how and where to use specialist electronic circuits to enhance your layout, Electronics and Wiring for Model Railways will help you to achieve a reasonably sophisticated layout. This book gives an overview of the geometry required for building successful model railways and includes clear explanations of electronics and electrical components. Comparisons of direct control and digital command control (DCC) are given along with step-by-step instructions for wiring the track, signals, buildings and lighting. Reviews of electrical systems, power supplies, wires and cable, control panels and switches are included along with detection, testing and troubleshooting tips. Finally, appendices of terminology, codes and symbols used for both electronics and model railway track plans, together with capacitor conversion tables.

Churchill's Pocketbook of Orthopaedics, Trauma and Rheumatology offers a practical guide to these three combined disciplines in a handy pocketbook format and is ideal for medical students, junior doctors and trainees. The book is perfect for clinical placements in orthopaedics, emergency medicine, rheumatology and general practice, as well as during the undergraduate musculoskeletal anatomy course. The book guides the reader through effective history taking, patient examination, and the selection and interpretation of routine investigations. There are sections on anatomy, paediatrics and trauma assessment, including pre- and post-operative care and complications, together with a comprehensive section on the common medications used in all three specialties. The book will help improve a reader's diagnostic skills and inform about current treatment options In this second edition the authors have updated the content to reflect changes in surgical practice and advances in therapeutics, as well as the molecular understanding of genetic and inflammatory disorders. Details of common procedures have been added. The updated layout has new 'overview' and 'hints and tips' boxes. The aim of the revision has been to provide concise and important information to both medical students revising for their exams, but also to junior doctors in their first years following graduation.
