Beam model of geometrical nonlinear longitudinal-flexural self-sustained vibrations of nanotube conveying fluid is obtained with account of nonlocal elasticity. The Euler-Bernoulli hypotheses are the basis of this model. The geometrical nonlinear deformat... see more

This research aimed to realize experimentally the facilevascular self-healing system in epoxy glass fibre reinforced composite. Using flexiblepolytetrafluoroethylene tubes as removable preforms, the channels were embeddedinto both neat epoxy resin and uni... see more

The ability to recognize the concept of early numbers in early childhood is very important to develop so that children are ready to take part in learning mathematics at a higher level. This study aims to determine the effect of mathematics learning approa... see more

In order to improve the fragile nature of concrete, and its low tensile strength, and with a view to giving it the desired properties, which serve to build more durable structures at less cost, the association of a self-consolidating concrete with fiber, ... see more

The paper presents the results of an investigation conducted to study the influence of fibre hybridization on the compressive strength, flexural strength, flexural fatigue and flexural toughness of the HybridFiber Reinforced Self Compacting Concrete (HyFR... see more

Self-compacting concrete (SCC) is a very fluid concrete and a homogeneous mixture that solves most of the problems related to ordinary concrete. Self-Compacting Concrete gets dense and compacted due to its own self-weight. An experimental investigation ha... see more

The aim of this research was to investigate the effectiveness of verbal self-instruction on sustained attention (based on Continuous Performance Test) among students with mathematics learning disabilities in Ardabil city. The study has used causal – compa... see more

In this paper an probabilistic model of the friction phenomena on the work- back up rolls contact surface has been presented. It has been shown that such character of the disturbance in distribution of zones with static and kinetic friction. can be regard... see more
