A study of reproducibility of kinesiology tape applications: review, reliability and validity
2017
Abstract Background Literature addressing the mechanical properties of kinesiology tape is quite scarce. There are no studies which focus on the mechanical characteristics of kinesiology tape, its mechanical properties, nor its adherence following the ISO international standard test methods for tape elongation. Methods This study quantified the mechanical characteristics of 380 samples of kinesiology tape from 19 different brands and in 4 different colors using a dynamometer. Mechanical testing was controlled by UNE EN ISO 13934-1. Results Significant differences were found between tape brands in terms of grammage, maximum force tenacity, work, pre-elongation and percentage elongation (P < …
Patient-specific simulation of the intrastromal ring segment implantation in corneas with keratoconus
2015
Purpose The purpose of this study was the simulation of the implantation of intrastromal corneal-ring segments for patients with keratoconus. The aim of the study was the prediction of the corneal curvature recovery after this intervention. Methods Seven patients with keratoconus diagnosed and treated by implantation of intrastromal corneal-ring segments were enrolled in the study. The 3D geometry of the cornea of each patient was obtained from its specific topography and a hyperelastic model was assumed to characterize its mechanical behavior. To simulate the intervention, the intrastromal corneal-ring segments were modeled and placed at the same location at which they were placed in the s…
Lines or Dots? Reproduction Processes in Handbooks on Illustration, 1890s-1910s
2016
International audience; This chapter examines the way that black and white illustrators came to terms with the industrial use of photomechanical processes and the major changes that occurred in the reproduction of illustrations from the 1890s to the early decades of the 20th century. It explores how handbooks on illustration and illustrators’ autobiographies reflected the need to preserve the so-called “vitality” of the graphic line, an autographic trace of the artist’s gesture. It focuses on the contemporary description and reception of half-tone, the screened process that breaks up tone into dots and that was used to reproduce wash, watercolour, and photographs. This process was often cri…
