Pilot-scale petroleum refinery wastewaters treatment systems: performance and microbial communities' analysis by Karray, Fatma

“…The reduction of the COD, BOD5, phenols, and the total petroleum hydrocarbon (TPH) reached 82.10%, 85.87%, 91.63%, and 81.11%, respectively at high hydraulic residence time (HRT = 10 days). Decreasing HRT to 5 and 2.5 days led to a decrease in the efficiency of the process and a decrease in biomass concentration was also observed (<1000 mg/l). …”

Asymmetric effects of oil price shocks on the demand for money in Algeria by Amirouche, Chelghoum

“…This paper investigates the symmetric and asymmetric effects of real oil prices on real money demand in Algeria over the period 1999:Q1–2020:Q1. Using a linear autoregressive distributed lag model (ARDL), and a nonlinear autoregressive distributed lag model (NARDL), we find no evidence of a long-term relationship among the variables. …”
