Abstract. The research program deals with fluid-structure interaction (FSI), a challenging field of engineering, practical application on aerospace problems such as the flutter, an instability problem due to aeroelastic excitations. goal is find suitable way deal flutter in two macro fields, fluid and structure, are modelled mid high-level accuracy. Moreover, creation interface could be useful ...

Abstract The meshing technique represents the capability to discretize domain of interest, fit real physical continuum in best possible way. most used approach is finite-element method (FEM), a numerical solve partial differential equations. To overcome classical issues presented by FEM, other models are investigated. goal allow problem be discretized elements represented arbitrary polygons, wh...

Neodiogmites Carrera, 1949, a rare Neotropical genus of Asilidae, is revised and divided into three species groups: (1) the melanogaster group, including N. carrerai Artigas & Papavero, N. melanogaster (Wiedemann, 1821), N. tenebrosus Carrera and N. carolindae sp. nov.; (2) the alexanderi group, including N. atriapex (Carrera & Papavero), N. alexanderi (Carrera), N. mixtus (Carrera), N. modestu...

Abstract. Variable stiffness composites present additional tailoring capabilities if compared to classical straight fiber composites. However, the fabrication of these advanced leads inevitably presence manufacturing signatures such as gaps and overlaps, which alter mechanical behavior laminated components. In this work, fundamental frequency variable laminates with overlaps is studied. The Def...

Background: Complementary and alternative medicines are increasingly used for the treatment of asthma worldwide. A five-herb herbal formula (CUF) has been found to be effective and safe in an animal model of asthma and in a preliminary clinical study. Objective: The objective of this study was to evaluate the safety and efficacy of CUF in children suffering from asthma. Design: A randomized, do...

A major cause of ultrafiltration (UF) membrane fouling is the accumulation of microorganisms and their associated soluble products. To mitigate fouling the application of pulsed short-wavelength ultraviolet (UVC) light (around 254 nm) within the membrane tank together with pre-coagulation was investigated. In mini-pilot-scale tests carried out in parallel with conventional pre-treatment (CUF), ...

This paper proposes the use of Jacobi polynomials to approximate higher-order theories beam, plate, and shell structures. The Carrera unified formulation is used in this context express displacement kinematics a hierarchical form. In manner, classical complex can be implemented with ease. Particular attention focused on attenuation correction shear locking. Therefore, reduced integration as wel...

Ultrafiltration has been used successfully in a variety of applications in the perioperative setting to assist in hemoconcentration and volume reduction. This study was designed to investigate the effects of aggressive conventional hemofiltration on bypass urine production, fluid balance, and renal performance in the 24 hours after bypass procedures in the adult population. A prospective, rando...
