In Korea, irrigation technology using subsurface drip (SDI) is new in agriculture system. Many limitations of SDI are not well known. can damage crops from overwatering. To address this weakness, it important to improve and test the applicability with air injection (oxygation). Therefore we investigated soil oxygen (O2) carbon dioxide (CO2), root characteristics yield maize two conditions moist...

Venturi-type cavitation reactors still appear as the most promising candidates for industrial-scale production due to their cheapness and ease of construction, scaling, replicability. The effects temperature on hydrodynamic cavitating flows in a Venturi section are investigated find optimum reacting conditions enhancing treatment intensity. flow varied with 4 different rates wide range temperat...

Akarsularda bulunan çözünmüş oksijen miktarı, hem suyun kalitesini gösteren de suda yaşayan canlıların ihtiyaç duyduğu önemli etkendir. Hidrolik yapıların akarsular ile temas etmeleri miktarına oranda etki etmektedir. Kaskatlar ve venturiler suların havalandırılmasında kullanılan hidrolik yapılardır. Venturi sistemlerinde daralan kesit içerisinde ilerleyen hızının ani bir şekilde artması birlik...

A laboratory flotation column equipped with Venturi aerators and an adjustable froth removal system was used to study the effect of calcium soap and a mixture of calcium soap/alkyl phenol ethoxylate surfactant on ink and fibres transfer during flotation de-inking of a 50% old newprint (ONP) / 50% old magazines (OMG) recovered papers mixture. Mass transport phenomena determining the yield of the...
