A state-of-the-art review on spent coffee ground (SCG) pyrolysis for future biorefinery
(
Elsevier Ltd
, 2022 , Article)
Coffee is a globally consumed beverage that produces a substantial amount of valuable organic waste known as spent coffee grounds (SCG). Although SCG is a non-edible biomass, research initiatives focused on valorizing/utilizing ...
Optimization of thermostable proteases production under agro-wastes solid-state fermentation by a new thermophilic Mycothermus thermophilus isolated from a hydrothermal spring Hammam Debagh, Algeria
(
Elsevier Ltd
, 2022 , Article)
The present work investigates for the first time the presence and isolation of the thermophilic fungi from hydrothermal spring situated at the locality of Guelma, in the Northeast of Algeria. The production of the thermostable ...
Health risk assessment induced by trace toxic metals in tap drinking water: Condorcet principle development
(
Elsevier Ltd
, 2022 , Article)
Acute exposure to trace metals (TMs) in water is hazardous to human health. The average concentrations (Cavg.) and carcinogenic (CAR) and non-carcinogenic (non-CAR) risks of eight TMs to World Health Organization's (WHO) ...
Investigation of thin-film composite hollow fiber forward osmosis membrane for osmotic concentration: A pilot-scale study
(
Springer
, 2022 , Article)
The current study applied the forward osmosis (FO) based osmotic concentration (OC) process at the pilot-scale for concentrating synthetic feed solution (FS). The process water (PW) salinity represents effluents from the ...
Adsorption of CO2 on Cu/SiO2 nano-catalyst: Experimental and theoretical study
(
Elsevier B.V.
, 2022 , Article)
Copper-based silica is a promising catalyst for several reaction pathways for CO2 conversion to hydrocarbons. The activity of this catalyst in terms of conversion and product selectivity is affected by CO2 adsorption, ...
Synthesis and evaluation of a novel polyacrylamide functionalized nano-silica as a calcium carbonate inhibitor in upstream applications
(
Elsevier B.V.
, 2022 , Article)
Calcium carbonate scale forms in production and injection wells, precipitating upon pressure and temperature changes, incompatible water mixing, and dehydration. Production shutdown is one of the most dramatic consequences ...
A CFD- RSM study of cuttings transport in non-Newtonian drilling fluids: Impact of operational parameters
(
Elsevier B.V.
, 2022 , Article)
Cuttings removal out of the wellbore represents a real barrier for successful drilling operations. The performance of hole cleaning is determined by several factors. The current article provides a theoretical study of the ...
Enhancing the flocculation of stable bentonite suspension using hybrid system of polyelectrolytes and NADES
(
Elsevier B.V.
, 2022 , Article)
In this study, the influence of a hybrid coagulation/flocculation process on the electrokinetic of highly stable bentonite suspension has been examined. Choline chloride (ChCl) based natural deep eutectic solvent (NADES) ...
Performance of THz Communications Over Cascaded RISs: A Practical Solution to the Over-Determined Formulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Article)
As a last resort for radio frequency communication, Terahertz bands (0.1-10 THz) are targeted thanks to their ability to provide ultra-wide bandwidth satisfying varieties of emerging applications. However, the waves ...
Robust R-Peak Detection in Low-Quality Holter ECGs Using 1D Convolutional Neural Network
(
IEEE Computer Society
, 2022 , Article)
Objective: Noise and low quality of ECG signals acquired from Holter or wearable devices deteriorate the accuracy and robustness of R-peak detection algorithms. This paper presents a generic and robust system for R-peak ...
