In this study, an electro-oxidation (EO) process using graphite electrodes as electrode pairs was used for the removal of chemical oxygen demand (COD), ammoniacal nitrogen (NH4+-N), and color from real textile printing wastewater.The effects of solution pH, sodium chloride (NaCl) dosage, sodium hypochlorite (NaOCl), which is the oldest and still mo
Abstract We consider in this paper the problem of phase offset and copyright Frequency Offset (CFO) estimation for Low-Density Parity-Check (LDPC) coded systems.We propose new blind estimation techniques based on the calculation and minimization of functions of the Log-Likelihood Ratios (LLR) of the syndrome elements obtained according to the parit
Abstract A facile and environmentally friendly ion exchange-assisted surface passivation (IASP) strategy is presented for synthesizing red emitting Mn4+-activated fluoride phosphors.A substantial, pristine Mn4+-free shell layer, applied as a coating to Mn4+ doped potassium iphone 11 price edmonton fluorosilicate K2SiF6:Mn4+ (KSFM) phosphors, enhanc
Alumina ceramics are widely used because of chemical corrosion resistance.Although alumina ceramics can resist many strong acids and organic acids, be corroded easily by HF due to silicon components in raw materials.This work aimed to reveal the effect of La2O3 on HF/HCl resistance of the alumina ceramic containing SiO2.The X-ray diffractometer (XR
