Practical Handbook for Small-Gauge Vitrectomy A Step-By-Step Introduction to Surgical Techniques, Second Edition
Practical Handbook for Small-Gauge Vitrectomy: A Step-By-Step Introduction to Surgical Techniques, Second Edition by Ulrich Spandau
English | EPUB | 2018 | 382 Pages | ISBN : 3319896768 | 168 MB
Since publication of the first edition of this book in 2012 vitreoretinal surgery has marched with huge steps forward. In 2012 23G was standard, today 25G and 27G are the most commonly used gauge sizes for vitrectomy. In 2012 the cutting rate was 5.000 cuts/min and today with the development of a novel vitreous cutter the cutting rate has increased to 16.000 cuts/min. The advent of 25G/27G made the instruments smaller and surgery less traumatic.



Pedestrian Fall Safety Assessments Improved Understanding on Slip Resistance Measurements and Investigations
Pedestrian Fall Safety Assessments: Improved Understanding on Slip Resistance Measurements and Investigations by In-Ju Kim
English | EPUB | 2017 | 276 Pages | ISBN : 331956241X | 4 MB
This book examines pedestrian shoe-floor slip resistance from an engineering standpoint in order to better understand friction and wear behavior. This analysis includes an extensive investigation into the surface properties of shoes and flow, and the measurement of dynamic friction and other mechanical and physical aspects of shoe-floor tribology. Lastly, the book proposes a measurement concept for the identification and classification of operational floor surfaces under a range of different conditions.
