limited water resources, especially in iran, require most effective method of water use to avoid losses. one of the important parameters in irrigation is water distribution uniformity coefficient (cu) in sprinkler irrigation. cu in every irrigation depends on pressure heads (p), riser height (rh), distance between sprinklers on lateral pipes (sl), and the distance between lateral pipes (sm). th...

A bioreactor refers to any manufactured or engineered device that supports a biologically active environment. These kinds of reactors are designed to treat wastewater treatment. Volumetric mass transfer coefficient and the effect of superficial gas velocity, as the most important operational factor on hydrodynamics, in three-phase airlift reactors are investigated in this study. The experiments...

Bone grafting of the patellar defect from harvest of the central third bone-patellar tendon-bone autograft in anterior cruciate ligament (ACL) reconstruction has been advocated by some authors to decrease the risk of patellar fracture from the existing stress riser as well as decrease postoperative donor site pain. We present a method of harvesting bone reamings during ACL reconstruction that i...

This note addresses the stabilization problem of a marine structure (i.e. cable/riser), connected to a surface vessel at one end and to a thruster unit at the other. Here, only lateral motion is considered. Based on boundary measurements, stabilizing control laws are designed. The controllers consist only on feedback from boundary measurements. The costs are thus minimized and the spillover ins...

For the purpose of understanding mechanism grain refinement in cast metal by mechanical vibration, demonstration tests were conducted using an ammonium chloride solution. Ammonium solution and molds with various shape prepared for water model experiment. In case open mold, crystals crystallized on mold wall grew toward center without vibration. However, when vibration was applied, countless gen...
