In this article, we propose a new dynamic model of Cosserat beams in view its application to continuum and soft robotics manipulation locomotion. contrast usual approaches, it is based on the nonlinear parameterization beam shape by strain fields their reduction functional basis modes. While remaining geometrically exact, approach provides us with minimal set ordinary differential equations Lag...

conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...

biomechanical properties of soft tissue, such as liver, are important in modeling computer aided surgical procedures. experimental evidences show that liver tissue is transversely isotropic. in this article, considering the liver tissue as an incompressible fiber-reinforced composite with one family of fibers, an exponential strain energy function (sef) is proposed. the proposed sef is based on...

probiotics, living microorganisms which when used in adequate amounts, have health benefits on the host, have attracted a considerable deal of interest in the biotechnology market. various prokaryotic and eukaryotic microbes have been studied for probiotic purposes in human and animals. lactobacillus and bifidobacterium are the main probiotic genera; however, there are reports on the probiotic p...

Nowadays, the technology intends to use materials such as magnesium alloys due to their high strength to weight ratio in engine components. As usual, engine cylinder heads and blocks has made of various types of cast irons and aluminum alloys. However, magnesium alloys has physical and mechanical properties near to aluminum alloys and reduce the weight up to 40 percents. In this article, a new ...
