• Full-scale hybrid MABRs fed with anaerobic sludge were monitored for three years. Nitrification performance was lowest at the ORP. Nitrifying organisms’ abundance significantly higher highest High of Fe and S compounds in MABR biofilm under Membrane-Aerated Biofilm Reactors (MABRs) are becoming a popular process intensification alternative within wastewater treatment plants (WWTP). Indeed, ni...

Recently we have evaluated the matrix elements 〈Orp〉, where O = {1, β, iαnβ} are the standard Dirac matrix operators and the angular brackets denote the quantum-mechanical average for the relativistic Coulomb problem, in terms of generalized hypergeometric functions 3F2 (1) for all suitable powers and established two sets of Pasternack-type matrix identities for these integrals. The correspondi...

Conventional wastewater treatment processes are challenged by the need to effectively reduce pollutant loads before disposal or reuse, as composition and concentration of contaminants in brewery change with time. This results variation oxidation-reduction potential (ORP) affluent. Hence, current study is aimed at application ORP a real-time tool monitor quality. Other physicochemical parameters...

Abstract Introduction Although the apnea-hypopnea index (AHI) remains gold-standard metric of severity obstructive sleep apnea (OSA), it is often criticized for its limitations. The odds ratio product (ORP), a continuous standardized measure depth that ranges from 0 (deep sleep) to 2.5 (full wakefulness), has been proposed as potential EEG-based alternative assess OSA, including association wit...

Abstract Introduction Previous research has shown mixed results when it comes to electronic device use and the impact on sleep quality. The of devices before bedtime can quality through engaging content blue light melatonin secretion. In present study, we assessed relationship between under real-world conditions. Methods Nineteen participants (age 41.1±10.9; 9 females) recorded their with in-ho...
