13. Behavior and design of built-up compressed steel members composed of concentric hot rolled circular hollow sections
Abstract This research presents a study of the behavior of built-up compressed steel members composed of concentric hot rolled circular hollow sections. The use of these members is an innovative solution of practical interest for situations in which a single member does not reach the required compressive strength. Some technically and economically viable de

14. An Innovative Structural Fatigue Monitoring Solution for General Aviation Aircraft
ABSTRACT: This article proposes a novel and effective solution for estimating fatigue life of General Aviation (GA) airframes using flight data produced by digital avionics systems, which are being installed or retrofitted into a growing number of GA aircraft. In the proposed implementation, a flight dynamics model is adopted to process the recorded flight d

15. Development and validation of a stability indicating HPLC method to determine diltiazem hydrochloride in tablets and compounded capsules
ABSTRACT A stability indicating HPLC method to determine diltiazem hydrochloride (DTZ) in tablets and compounded capsules was developed and validated according to Brazilian and the International Conference on Harmonization (ICH) guidelines. The separation was carried out on a Purospher Star® C18 (150 x 4.6 mm i.d., 5 µm particle size, Merck Millipore) anal

16. Application of a Greedy Algorithm to Military Aircraft Fleet Retirements
ABSTRACT This article presents a retirement analysis model for aircraft fleets. By employing a greedy algorithm, the presented solution is capable of identifying individually weak assets in a fleet of aircraft with inhomogeneous historical utilization. The model forecasts future retirement scenarios employing user-defined decision periods, informed by a cost

17. Structural Analysis of the Double Bottom Structure During Ship Grounding by Finite Element Approach
Abstract Possibility of a water-transportation mode to experience numerous accidental loads is predicted limitless and always demand sustainable analysis. Impact phenomenon raises as main reason of environmental damage, for instance, grounding contributes in form of short-time impact and produces massive damage on the bottom structure of a marine vessels, e.

18. Development of a computational instrument using a lagrangian particle method for physics teaching in the areas of fluid dynamics and transport phenomena
Abstract Particle methods are an alternative to the traditional mesh Eulerian methods for solution of fluid dynamics and transport phenomena problems. The Lagrangian Meshless Smoothed Particle Hydrodynamics (SPH) method presents advantages compared to mesh methods as a better visualisation of the spatio-temporal evolution of the flow (and the fluid propertie

19. Development and validation of a HPTLC method for analysis of Sunitinib malate
ABSTRACT A simple high performance thin layer chromatography (HPTLC) has been developed and validated for determination of sunitinib malate and possible impurities. The samples were applied in forms of bands on an aluminum TLC plate pre-coated with silica gel and were separated using dichloromethane: methanol: toluene: ammonia solution as the mobile phase. S

21. Portuguese validation of the Social Competence and Behavior Evaluation Scale (SCBE-30)
Abstract Aim The Social Competence and Behavior Evaluation Scale (SCBE-30) is a 30-item questionnaire designed to assess preschoolers’ behavioral problems (externalizing and internalizing) and social competence. It is widely used in the developmental research. This study aims to contribute to the adaptation and validation of the Portuguese version of the

22. Elasto-Plastic Stress Analysis in Rotating Disks and Pressure Vessels Made of Functionally Graded Materials
Abstract A new elastio-plastic stress solution in axisymmetric problems (rotating disk, cylindrical and spherical vessel) is presented. The rotating disk (cylindrical and spherical vessel) was made of a ceramic/metal functionally graded material, i.e. a particle-reinforced composite. It was assumed that the material's plastic deformation follows an isotropic

23. Experimental Validation of a Cardiac Simulator for in vitro Evaluation of Prosthetic Heart Valves
Abstract Objective: This work describes the experimental validation of a cardiac simulator for three heart rates (60, 80 and 100 beats per minute), under physiological conditions, as a suitable environment for prosthetic heart valves testing in the mitral or aortic position. Methods: In the experiment, an aortic bileaflet mechanical valve and a mitral biop

24. The Caughey absorbing layer method - implementation and validation in Ansys software
AbstractThis paper addresses the Caughey Absorbing Layer Method (CALM) performance in the one-dimensional problem and its implementation in commercial software, with possibility of direct extension to two-dimensions. The adequacy and numerical efficiency is evaluated using three different error measures and five different variations of the damping profile. O
