A new approach for analyzing cracked problems in 2D orthotropic materials using the well-known element free Galerkin method and orthotropic enrichment functions is proposed. The element free Galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. In this study, element free Galerkin is extrinsically enriched by the recently developed crack-tip orthot...

Wemodel the evolution of dynamomaintained magnetic fields in a barred spiral galaxy. The velocity fields are taken from N-body dynamical simulations. The important feature is the presenceof strong, unsteadynon-circular gasmotions, driven by the central bar, The nonlinear dynamo calculations are carried out with both two dimensional (thin disc approximation) and three dimensional codes. The resu...

INTRODUCTION This study aimed to explore the effect of carbon dioxide (CO2) pneumoperitoneum on tumor proliferation and metastasis in an orthotropic xenograft nude mice model of human renal cell carcinoma (RCC) and evaluate the safety of CO2 pneumoperitoneum laparoscopy for treating RCC. MATERIAL AND METHODS RCC 786-0 cells were injected to establish an orthotropic xenograft model. Fifty nude...

Recent morphological studies have demonstrated a laminar (sheet) organization of ventricular myofibers. Multiaxial measurements of orthotropic myocardial constitutive properties have not been reported, but regional distributions of three-dimensional diastolic and systolic strains relative to fiber and sheet axes have recently been measured in the dog heart by Takayama et al. [30]. A three-dimen...

OBJECTIVE To determine the effectiveness of the use of the SIP score and the quality of life impairment in patients with ileal conduit and orthotropic ileal derivations by Hautmann and AbolEnein/Ghoneim. METHODS Prospectively evaluated 146 patients in different age groups. In 66 patients ileal conduit derivation was performed, in 20 patients orthotropic derivation using Hautman technique was ...

A complete approach for the search of top-quality six-bar linkages based on four-bar generating coupler curves with circular regions has been developed. The includes a robust algorithm to high-accuracy in and fitness function able evaluate quality resulting linkage. is used explore design space order optimal dwell identify types that provide best dwells according established criteria.
