flow characteristics and rheological parameters of “malas yazdi” pomegranate (punica granatum l.) juice were investigated using rotational viscometer at different temperatures (10, 20, 30, 40, 50, 60 and 70ºc) and concentrations (12, 22, 32, 42 and 52º brix). the experimental data had the best fitness with herschel-bulkley model and the values of flow behavior index (n) varied between 0.97 and ...

Higher concentration is beneficial for the Paste and Thickened Tailings (PTT) operation in metal mine. Partial paste thickeners are produced lower density underflow. Flocculated tailings intended to form a water entrapped network structure thickener, which detrimental underflow concentration. In this study, continuous thickening experiment was carried out ultra-fine tungsten study influence of ...

The flocculation that takes place in the central feedwell of thickener plays a crucial role coal-slurry thickening process, which is not only complex but also largely influenced by flow characteristics. A coupled computational fluid dynamics–population balance model (CFD–PBM) was used to flocculation-thickening behaviour an industrial-scale gravity thickener. initialisation parameters inlet wer...

objective: etching of enamel and dentin is an important step in restoration of teeth with composite resin ensuring the retention of restoration and decreasing microleakage. this in vitro study sought to compare the effects of kimiya and etch-rite acid etchants on the microleakage of composite restorations.   methods: this experimental study was conducted on 30 sound human molar teeth. class v c...

The purpose of this study was to quantify the occurrence and release of antibiotic resistant genes (ARGs) and antibiotic resistant bacteria (ARB) into the environment through the effluent and biosolids of different wastewater treatment utilities including an MBR (Membrane Biological Reactor) utility, conventional utilities (Activated Sludge, Oxidative Ditch and Rotatory Biological Contactors-RB...
