Emergency laparoscopic surgery in the elderly and frail patient English | 2021 | ISBN: 3030799891 | 340 Pages | PDF EPUB | 17 MB The global population is aging rapidly, and as a result emergency abdominal surgery for acute abdomen in the elderly has become a global issue. Demographic changes in the population have also altered the profile of emergency abdominal surgery, with typical causes of acute abdomen in the elderly including acute cholecystitis, incarcerated hernia, bowel obstruction and appendicitis. In these patients, recovery from surgery is often complicated, leading to longer hospital stays compared with younger patients. Laparoscopy in the emergency setting is well established and offers a number of advantages over open surgical approaches, such as reduced postoperative pain, length of hospital stay and complication rates. While laparoscopic surgery for acute diverticulitis has become more widespread, in other conditions, like small bowel obstruction and perforated peptic ulcer, laparotomy is still used in about 70% of cases. Further, despite the urgent need for knowledge regarding surgical treatment of acute abdomen in the elderly, there is still a lack of evidence in this relevant clinical field.  Electrospinning of Graphene English | 2021 | ISBN: 3030754553 | 183 Pages | PDF EPUB | 60 MB This book presents electrospinning as a processing technique in the field of graphene research. It brings together the current state of the art of processing, properties, and applications in different fields of science and technology of graphene and derived materials. The book not only discusses the various aspects of electrospun graphene but also covers the limitation and drawbacks of graphene owing to some of its intrinsic properties.  Electromechanics and Robotics English | 2022 | ISBN: 9811628130 | 507 Pages | PDF | 14 MB This book features selected papers presented at the 16th International Conference on Electromechanics and Robotics 'Zavalishin's Readings' - ER(ZR) 2021, held in St. Petersburg, Russia, on April 14-17, 2021. The contributions, written by professionals, researchers and students, cover topics in the field of automatic control systems, electromechanics, electric power engineering and electrical engineering, mechatronics, robotics, automation and vibration technologies. The Zavalishin's Readings conference was established as a tribute to the memory of Dmitry Aleksandrovich Zavalishin (1900-1968) - a Russian scientist, corresponding member of the USSR Academy of Sciences, and founder of the school of valve energy converters based on electric machines and valve converters energy. The first conference was organized by the Institute of Innovative Technologies in Electromechanics and Robotics at the Saint Petersburg State University of Aerospace Instrumentation in 2006. The 2021 conference was held with XV International Conference "Vibration-2021. Vibration technologies, mechatronics and controlled machines" and VI International Conference "Electric drive, electrical technology and electrical equipment of enterprises", and was organized by St. Petersburg State University of Aerospace Instrumentation (SUAI), St. Petersburg Federal Research Center of the Russian Academy of Sciences (SPC RAS), Southwest State University (SWSU) and Ufa State Oil Technical University (USPTU).  Electrical Steels, Volume 2 : Performance and Applications by Anthony Moses, Philip Anderson English | 2019 | ISBN: 1785619721 | 664 Pages | ePUB | 16 MB  Electrical Steels, Volume 1 : Fundamentals and Basic Concepts by Anthony Moses, Philip Anderson English | 2019 | ISBN: 1785619705 | 584 Pages | ePUB | 11 MB  Economic Freedom and the American Dream by J. Shaanan English | PDF | 2010 | 256 Pages | ISBN : 0230617751 | 1.5 MB Shaanan challenges the conventional view that unrestricted economic freedom enhances our economic and political well being.

Ecological Physiology of Daily Torpor and Hibernation English | 2021 | ISBN: 303075524X | 326 Pages | PDF | 8 MB This book provides an in-depth overview on the functional ecology of daily torpor and hibernation in endothermic mammals and birds. The reader is well introduced to the physiology and thermal energetics of endothermy and underlying different types of torpor. Furthermore, evolution of endothermy as well as reproduction and survival strategies of heterothermic animals in a changing environment are discussed.  Ecological Continuum from the Changjiang (Yangtze River) Watersheds to the East China Sea Continental Margin by Jing Zhang English | PDF | 2015 | 209 Pages | ISBN : 3319163388 | 16.9 MB The book provides a cross-disciplinary and multi-scale assessment of a world top river, the Changjiang (Yangtze River) and its adjacent marginal environment, the East China Sea. The studies in this volume bridges the watersheds of the river and the marginal sea through a combined approach of hydro-dynamics, geochemistry, sedimentary processes, ecology and fishery. The response of ecosystem to the external driving forces is examined via process-oriented observations, mesocosm experiments and numerical simulations in combination. The lessons learnt from the case studies of Changjiang and East China Sea can be beneficial to those who are doing inter-disciplinary researches in the continuum from watersheds to continental margins.
