In the Tabas coal preparation plant (SE Iran), -50 + 6 mm raw coal was treated in a 700 mm two-stage two-density Tri-Flo dynamic dense medium separator. In order to study the circuit performance and to evaluate the separator efficiency, 32 mm cubic density tracers were used in the range of 1.28-2.1 g/cm3 and under different operational conditions. The performance of Tri-Flo was evaluated in a r...

Abstract Tri-flo cyclone, as a dense-medium separation device, is one of the most typical environmentally friendly industrial techniques in coal washery plants. Surprisingly, no detailed investigation has been conducted to explore effectiveness tri-flo cyclone operating parameters on their representative metallurgical responses (yield and recovery). To fill this gap, work for first time process...

Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...

There is currently a paucity of preclinical models available to study the metastatic process in esophageal cancer. Here we report FLO-1, and its isogenic derivative FLO-1LM, as two spontaneously metastatic cell line models of human esophageal adenocarcinoma. We show that FLO-1 has undergone epithelial-mesenchymal transition and metastasizes following subcutaneous injection in mice. FLO-1LM, der...

Background: The COVID-19 pandemic has forced many educational institutions to shift to flexible learning options (FLO), which require technology in teaching. Digital immigrant nurse educators, who are educators born before 1985, may need help adopting FLO due to their limited knowledge and skills in technology. This study aims to explore the experiences of digital immigrant nurse educators' cha...

The outer cell wall of the yeast Saccharomyces cerevisiae serves as the interface with the surrounding environment and directly affects cell-cell and cell-surface interactions. Many of these interactions are facilitated by specific adhesins that belong to the Flo protein family. Flo mannoproteins have been implicated in phenotypes such as flocculation, substrate adhesion, biofilm formation, and...

This paper studies the recovery of a superposition of point sources from noisy bandlimited data.In the fewest possible words, we only have information about the spectrum of an object in the low-frequency band[−flo, flo] and seek to obtain a higher resolution estimate by extrapolating the spectrumup to a frequency fhi > flo. We show that as long as the sources are separated b...

A quantitative method was developed for analyzing mixtures containing fatty esters and tri(TG), di(DG) and monoglycerides (MG) obtained by the transesterification of vegetable oils. Analyses were performed by thin layer chromatography (TLC)/flame ionization detection (FlO) with an latroscan TH-10 instrument. Stearyl alcohol served as an internal standard. From plots of area and weight ratios of...

This study evaluated the relationship between florfenicol resistance and flo genotypes in 1,987 Escherichia coli isolates from cattle. The flo gene was detected in 164 isolates, all of which expressed resistance to florfenicol at MICs of >/=256 microg/ml. The florfenicol MICs for all isolates that lacked flo were </=16 microg/ml.
