Sommario/riassunto |
|
The basic theory of sheet metal forming in the automotive, appliance and aircraft industries is given. This fills a gap between the descriptive treatments in most manufacturing texts and the advanced numerical methods used in computer-aided-design systems. The book may be used by lecturers in undergraduate courses in manufacturing; plentiful exercises and worked examples provide quantitative tutorial problems for students. A separate, but related simulation software package advertised on this page enables students to explore the limits of processes and understand the influence of dif |

Sommario/riassunto |
|
Ultrasound plays an integral part in the diagnosis and management of many gynaecological conditions; indeed, ultrasound forms part of the RCOG's mandatory training programme for doctors wishing to specialise in obstetrics and gynaecology. This book will be of use to both trainees and those already in clinical practice looking for a user-friendly reference guide. The use of ultrasound in gynaecology goes well beyond simple picture recognition: a skilful gynaecological sonographer will bring together scan findings and the clinical scenario to enhance patient care. This leads to targeted investigations and strategies for intervention. This book covers all aspects of the use of ultrasound in the fields of gynaecology and early pregnancy, with the contents including: postmenopausal bleeding; adnexal masses; pelvic pain; reproductive medicine; miscarriage; ectopic pregnancy; and ovarian cysts. |
