This is the second edition of a well-received book that reflects the state of the art in diagnosis and treatment of acute abdominal disorders in the pregnant patient. It addresses a wide range of conditions - whether associated with or incidental to pregnancy - ranging from very rare to more common ones, such as acute appendicitis and acute cholecystitis.

This book highlights original research and recent advances in various fields related to smart cities and their applications. It gathers papers presented at the Fourth International Conference on Smart City Applications (SCA19), held on October 2–4, 2019, in Casablanca, Morocco.

This book constitutes selected papers from the First International Symposium on Geometry and Vision, ISGV 2021, held in Auckland, New Zealand, in January 2021. Due to the COVID-19 pandemic the conference was held in partially virtual format.
The 29 papers were thoroughly reviewed and selected from 50 submissions. They cover topics in areas of digital geometry, graphics, image and video technologies, computer vision, and multimedia technologies.

Inflammatory pathology of the spine is an underestimated, but widespread condition among the population. This atlas shares essential information and case studies on key aspects of MRI for rheumatic inflammatory lesions of the osteoarticular structures of the spine, offering radiologists and clinicians a valuable guide to the management of patients with inflammatory back pain. In particular, this richly illustrated and comprehensive case-based atlas documents the MR findings observed in seronegative spondyloarthritis and rheumatoid arthritis of the cervical spine, providing guidelines on selecting the appropriate imaging protocol.
