Conventional hydrocarbon oil cannot adhere effectively to oxidized coal, resulting in a low yield of clean coal. In this study, high-speed homogenizer was used emulsify LDD (laurylamine dipropylene diamine) and kerosene, which enhanced the flotation efficiency The results showed an increase from 4.12% (only kerosene) 23.33% (emulsified oil). An contact angle indicated that mixture reagent can h...

results mycoflora profiles of fresh and stored rice grains showed that aspergillus species (37.3%, 40.7%) were the predominant fungal agents, followed by fusarium (21.6%, 16.2%), mucor (19.6%, 16.7%) and rhizopus (9.8%, 11.1%), respectively. in hplc analysis, most of the rice samples (96.7%) collected were found to be positive for fb1 with mean levels ranging from not detected to 56.2 mg/kg for...

this study aimed to construct the hydrate three-phase equilibrium curves for two typical iranian gas reservoir samples using a high-pressure visual cell. to do so, complete analysis of the reservoir fluids was obtained by different techniques of composition analysis i.e. gas chromatography (gc) and detailed hydrocarbon analysis (dha). using high-pressure visual cell the hydrate phase equilibriu...

background: this study investigated blackberry (persian mulberry) effects on apo a-i, apo b, high-sensitivity-c-reactive protein (hs-crp), and systolic blood pressure (sbp) and diastolic blood pressure (dbp) in dyslipidemic patients. materials and methods: in this 8-week randomized clinical trial, 72 dyslipidemic patients were randomly divided into two groups: intervention (300 ml/day blackberr...

conclusions although the results obtained with the use of different methods show an excellent correlation, when one particular sample is tested by different assays, the results are significantly different. it can be concluded that the national standardization program of hba1c measurement is necessary. background hemoglobin a1c (hba1c) testing devices are widely used to evaluate glycemic control...

Abstract In this work, the efficiency of a polyelectrolyte complex (PEC) to retain different cellulose micro/nanofibers (CMNFs) during paper formation and improve physical properties recycled unbleached fiber was analyzed. CMNFs were obtained from commercial bleached eucalyptus pulp (BEP) using PFI refiner followed by chemical treatment with oxalic acid at two concentrations. Finally, fibrillat...
