Carbon nanotubes (CNTs) are a novel nanomaterial with wide potential applications; however the adverse effects of CNTs following environmental exposure have recently received significant attention. Herein, we explore the systemic toxicity and potential influence of 0-1000 mg L(-1) the multi-walled CNTs on red spinach. The multi-walled CNTs exposed plants exhibited growth inhibition and cell dea...

The paper presents a numerical analysis of thick-walled PA66 GF30 moldings with the addition chemical blowing agent content 1-3 wt%, and obtained results were compared real object. Computer simulations performed using Moldex3D ® software. Based on analysis, it was found that regardless dose used, largest pores place in core sample. Moreover, size depends their number cross-section moldings. Com...

Abstract This paper presents a three-dimensional beam element for stability analysis of elastic thin-walled open-section beams in multibody systems. The model is based on the generalized strain formulation. In this formulation, set independent deformation modes defined which are related to dual stress resultants co-rotational frame. characterized by strains or deformations, expressed as analyti...
