Abstract Vertical agriculture in urban areas is a new phenomenon where interest needed order to develop. The objective of the research develop tower system vertical farming technique. In this research, could produce 624 plants. This made using PVC pipe with 26 holes per tower. Each set towers equipped an irrigation system, namely water pump drain nutrient pipe. way monitoring works that ESP 32 ...

This paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. To this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. The g...

in this research, the effect of friction between the liquid metal and the sand mould wall and the effect of passage of liquid through a vertical bend and through a ceramic filter on the fluid flow and the melt velocity has been studied by measuring the velocity of the melt and direct observation of the liquid flow through the different parts of a naturally-pressurized running system. the fricti...
