In this paper we present a biomechanical study to evaluate the efficiency of the motion of endoscopic robots in the colon, with a special focus on “inchworm” locomotion. A quasi-linear viscoelastic model for soft tissues has been introduced in order to find the mechanical behavior of colon and mesenteries. A study of efficiency of the motion phases, through biomechanical and geometrical factors...

The aim of this general article is to present an overview of the current knowledge about composition and structural changes and also about specific biomechanical alterations related to vitality loss or endodontic therapy. For a long time, these issues have been controversially approached from a clinical standpoint and are therefore still confusing for many practitioners. Vitality loss or endodo...

A fundamental question in the investigation of any sensory system is what physical signals drive its sensory neurons during natural behavior. Surprisingly, in the whisker system, it is only recently that answers to this question have emerged. Here, we review the key developments, focussing mainly on the first stage of the ascending pathway - the primary whisker afferents (PWAs). We first consid...

Leopards have been observed to ambush prey by jumping down on it from trees. There are both anecdotal reports and video recordings of this hunting behavior. Here we conducted a biomechanical analysis technique assess the degree risk for predator in such cases. We concluded that suffering severe injuries seems be too high usual way predation horned mammals as male impalas. Our results can useful...

purpose : to investigate the correlation between corneal biomechanical properties and tomographic parameters of pentacam methods : corneal biomechanical properties and tomographic results of 36 normal subjects were measured by ocular response analyzer (ora) and pentacam and the correlation between these two measurements were analyzed with pearson correlation test with spss version16. results : ...

INTRODUCTION Running, hopping and trotting animals can be modeled as spring-mass systems in which the mechanical behavior of the musculoskeletal system is represented as a leg spring. The stiffness of the leg spring is the primary determinant of the dynamics of running. Biomechanical studies have revealed that larger mammalian species have stiffer legs (Farley et al., 1993). Similarly, large ad...
