Zinnia elegans Jacq. is an ornamental plant, widely used in landscaping. Heavy-metal pollution urban and rural areas still increasing, which determines the actuality of studying plants’ reactions to pollutants. was not sufficiently studied this regard, so aim our research identify morphophysiological changes species under excess copper concentration soil. For this, we treated a growth substrate...

For axial piston units, product optimisation plays an essential role in the development phase, where efficient and price-attractive design manufacturing process is key to success of a product. Moreover, market needs are on lighter, more compact, efficient, reliable products designed limit. Therefore, reliability focus this work, research includes method analysis material stress calculation appl...

The accurate prediction of reference points on the axial stress–axial strain relationship fiber-reinforced polymer (FRP)-confined concrete is vital to pre-design structures made with this system. This study uses an artificial neural network (ANN) for predicting hoop rupture (εh,rup) and transition zone, namely (εc1) stress (f’c1), stress–strain curves FRP-confined concrete. These are key parame...
