Finite element analysis (FEM) has been conducted for case-bonded finocyl port propellantcross section under pressure loading conditions during burning. Peak strain is found todecrease in course of burning, hence, analysis of any intermediate configuration... see more

Finite element analysis of case-bonded solid propellants in finocyl port configuration hasbeen carried out using finite element method. The parametric studies have also been conductedfor loading conditions, material properties, and geometrical configurati... see more

Star port propellant grains have been extensively studied for their operating as well as geometrical parameters. It is observed that reduced tail-off and better neutrality cannot be achieved simultaneously in a configuration. Parametric study is conducted... see more

Radial outward burning tubular propellant grain gives progressive burning profile, but trimming port at one end to conical form gives close to neutral burning profile. Though this configuration is easy to realize, but closeform burnback equation for perfo... see more

Poisson's ratio of hydroxy-terminated polybutadine (HTPB)-based composite propellant is estimated from uni-axial tensile testing. Double dumbbell specimens as per ASTM D638 type IV standard were used and Poisson's ratio at break, obtained by cha... see more

Esta pesquisa tem como objetivo geral levantar teses e dissertações produzidas no Brasil e em Portugal sobre as metodologias didáticas para estudantes com deficiência visual (DV) no período de alfabetização em escolas regulares. Trata-se de uma revisão in... see more

The initial training of teachers assumes great responsibility in the methodo-logical renewal of teachers. This study aims to know the thinking of higher education students, future teachers, regarding their knowledge and attitudes towards the curricular in... see more

A computational procedure has been established to predict the slag in a practical solid rocket motor with submerged nozzle. Both single-phase and two-phase flow analyses have been performed in the rocket motor port. Three-dimensional Navier-Stokes equatio... see more

Este artigo analisa a relação entre publicidade, política e opinião comum no Portugal do século XVII. O caso da aclamação de D. João IV em Barcelos serve para ilustrar as implicações políticas do que chamamos de “desmaterialização” do público durante a Er... see more
