1. PARAMETERS FOR MODELING PASSIVE SUSPENSIONS OF SPRAY BARS
ABSTRACT The uniformity and quality of spraying depend on the stability of the spray boom, defined as the suspension system between the boom and the machine chassis. This paper presents a procedure for improving the performance of passive spray bar suspensions through parameter adjustment. Two multibody dynamics models of a tractor sprayer set were developed

2. Health-related physical fitness and weight status in 13- to 15-year-old Latino adolescents. A pooled analysis
Resumo Objetivo: Investigar a relação entre a aptidão física relacionada à saúde e o status do peso em adolescentes latinos de 13 a 15 anos. Método: A amostra final consistiu em 73.561 adolescentes entre 13 e 15 anos (35.175 meninas) do Chile (n = 48.771) e da Colômbia (n = 24.790). As aptidões cardiorrespiratória e musculoesquelética foram medi

3. Shear strength analysis of slabs without transverse reinforcement under concentrated loads according to ABNT NBR 6118:2014
Resumo A solicitação por cargas parcialmente distribuídas em lajes sem armadura transversal, frequente em tabuleiros de pontes, resulta na propagação horizontal da força cortante em direção aos apoios, situação na qual nem toda a largura da laje é mobilizada. Por esta razão, os modelos de resistência à força cortante de vigas e de resistência

4. Comparison of Developed Numerical Macro and Micro Masonry Models for Static and Dynamic Analysis of Masonry-infilled Steel Frames
Abstract First, the basic characteristics of macro and micro masonry models in numerical analyses of masonry structures are discussed. Afterwards, developed numerical macro and micro masonry models, intended for the nonlinear static and dynamic analysis of unreinforced and confined masonry walls, as well as of masonry-infilled frames, are briefly presented.

5. Superposition of Stress Fields in Diametrically Compressed Cylinders
Abstract The theoretical analysis for the Brazilian test is a classical plane stress problem of elasticity theory, where a vertical force is applied to a horizontal plane, the boundary of a semi-infinite medium. Hypothesizing a normal radial stress field, the results of that model are correct. Nevertheless, the superposition of three stress fields, with two

6. Ground reaction forces during level ground walking with body weight unloading
Background: Partial body weight support (BWS) systems have been broadly used with treadmills as a strategy for gait training of individuals with gait impairments. Considering that we usually walk on level ground and that BWS is achieved by altering the load on the plantar surface of the foot, it would be important to investigate some ground reaction force (

7. Synthesis and characterisation of polymeric nanofibers poly (vinyl alcohol) and poly (vinyl alcohol)/silica using indigenous electrospinning set up
Indigenous design and fabrication horizontal of electrospinning set up was developed to facilitate with double drum conveyor belt system to make ease in harvesting nanofibers rapidly. As a bench mark study, organic-inorganic nanofiber composite was synthesised employing our indigenous electrospinning set up. The aqueous solution of poly (vinyl alcohol) and p

10. Study of tension in the periodontal ligament using the finite elements method
Orthodontic movement is process of transformation of a physical stimulation into a force applied to a tooth, with a biological response identified as bone remodelling. Although it is possible to measure the force applied on a tooth, its distribution around the root is irregular forming areas of higher concentration of tensions, which do not correspond to the

12. Mechanical evaluation of space closure loops in Orthodontics
This study evaluated the mechanical performance of teardrop-shaped loops and teardrop-shaped loops with helix used in orthodontic space closure. Sixty retraction loops made with 0.019" x 0.025" stainless steel (SS) and beta-titanium (BT) wires were used. They were attached to a testing machine to measure the magnitudes of the sagittal force and the load-defl
