This study investigated the influence of experimental factors on the electrochemical cyanide destruction efficiency in a flow-through reactor using response surface methodology. Central composite experimental design was used to obtain the four main operating factors, such as current density, initial cyanide concentration, chloride concentration, and electrolysis time, on the response surface of...

in this study, activated sludge process for wastewater treatment in a refinery was investigated. for such purpose, a laboratory scale rig was built. the effect of several parameters such as temperature, residence time, effect of leca (filling-in percentage of the reactor by leca) and uv radiation on cod removal efficiency were experimentally examined. maximum cod removal efficiency was obtained...

Today’s unmanned aerial vehicles are being utilized by numerous groups around the world for various missions. Most of the smaller vehicles that have been developed use commercially-off-the-shelf parts, and little information about the performance characteristics of the propulsion systems is available in the archival literature. In light of this, the aim of the present research was to determine ...

Methods. Microscopic, cultural, biochemical, statistical. Results. The results research on properties DI...

Background/Aim: Papillary neoplasia encompasses both malignant and benign lesions, core needle biopsy (CNB) is crucial in their diagnosis. Histological findings determine management. Here we compare volumetric apparent diffusion coefficient (ADC) histogram analysis of carcinomas pathologies identified by histopathology from excisional biopsies. Methods: This retrospective study included 524 pat...

to achieve optimal yield and high production in wheat, need to adapt the plant's vegetative and reproductive growth stages to environmental conditions and increase use efficiency of production factors by desirable density. in order to study the effect of plant density on extinction coefficient and radiation use in modern and old wheat (triticum aestivum l.) genotypes, an experiment was conducte...
