Advances in research have led to the use of robotics in a range of surgical applications. Medical robotics: Minimally invasive surgery provides authoritative coverage of the core principles, applications and future potential of this enabling technology. Beginning with an introduction to robot-assisted minimally invasive surgery (MIS), the core technologies of the field are discussed, including localization and tracking technologies for medical robotics. Key applications of robotics in laparoscopy, neurology, cardiovascular interventions, urology and orthopaedics are considered, as well as applications for ear, nose and throat (ENT) surgery, vitreoretinal surgery and natural orifice transluminal endoscopic surgery (NOTES). Microscale mobile robots for the circulatory system and mesoscale robots for the gastrointestinal tract are investigated, as is MRI-based navigation for in vivo magnetic microrobots. Finally, the book concludes with a discussion of ethical issues related to the use of robotics in surgery. With its distinguished editor and international team of expert contributors, Medical robotics: Minimally invasive surgery is a comprehensive guide for all those working in the research, design, development and application of medical robotics for surgery. It also provides an authoritative introduction for academics and medical practitioners working in this field.

During their service life, most biomaterials and medical implants are vulnerable to tribological damage. In addition, the environments in which they are placed are often corrosive. The combination of triobology, corrosion and the biological environment has been named ‘bio-tribocorrosion’. Understanding this complex phenomenon is critical to improving the design and service life of medical implants. This important book reviews recent key research in this area. After an introduction to the topography of bio-tribocorrosion, Part one discusses different types of tribocorrosion including fatigue-corrosion, fretting-corrosion, wear-corrosion and abrasion-corrosion. The book also discusses the prediction of wear in medical devices. Part two looks at biological effects on tribocorrosion processes, including how proteins interact with material surfaces and the evolution of surface changes due to bio-tribocorrosion resulting from biofilms and passive films. Part three reviews the issue of bio-tribocorrosion in clinical practice, including dental applications and joint replacement as well the use of coatings and test methods for bio-tribocorrosion. With its international team of contributors, Bio-tribocorrosion in biomaterials and medical implants is a standard reference for those researching and developing medical devices as well as clinicians in such areas as dentistry and orthopaedic surgery. Reviews recent research in bio-tribocorrosion and its role in improving the design and service life of medical implants Discusses types of bio-tribocorrosion including fatigue and wear corrosion Examines biological effects on bio-tribocorrosion processes including interaction of proteins with metal surfaces

Baumwolle wird auf allen Kontinenten unter den unterschiedlichsten Umwelt- und Produktionsbedingungen angebaut. Sie ist ein wichtiger Rohstoff fA1/4r eine vielfAltige und profittrAchtige WertschApfungskette und wird weltweit an den BArsen gehandelt. Baumwolle steht im Mittelpunkt des Streits um Agrarsubventionen und ist ein wichtiges Instrument in der Entwicklungshilfe. An ihr haben internationale Chemiefirmen ebensoviel Interesse wie Vertreter der Akologischen Landwirtschaft, denn sie verbraucht im Vergleich mit anderen Kulturpflanzen die grAsste Menge an Wasser, DA1/4nger und Pestiziden. Vom Produzenten zum Konsumenten ging die Baumwolle schon zu Kolonialzeiten um die Welt, heute haben sich lediglich die Routen verAndert. So kann es sein, dass Baumwollfasern aus Texas zur Verarbeitung nach China geschickt werden, von dort auf den Laufsteg in Paris gelangen um schliesslich in der Altkleidersammlung nach Afrika zu reisen, wo sie als Secondhand-Mode getragen werden. Der Fotograf Hans Peter Jost hat auf seinen Reisen nach Indien, China, Brasilien, Amerika, Usbekistan, Mali und Tansania ein fotografisches Portrait der Baumwolle geschaffen: das Leben der Baumwollbauern und ihre Arbeitsbedingungen, den Anbau, Ernte, Verarbeitung und Vermarktung der Baumwolle. Christina Kleineidam, die den Fotografen auf seinen Reisen begleitet hat, beschreibt das Gesehene, und gibt Hintergrundinformationen zu den spezifischen Problemen der einzelnen LAnder. Die A-konomin Pietra Rivoli erlAutert in ihrem Vorwort die globalen ZusammenhAnge von Anbau und Vermarktung der Baumwolle.
