Shear and Tensile Strength Measurements of CaCO 3 Cemented Bonds between Glass Beads Treated by Microbially Induced Carbonate Precipitation
(
American Society of Civil Engineers (ASCE)
, 2023 , Article)
The particle-scale shear and tensile strength measurements of microbial-induced calcite precipitation (MICP) treatment have been investigated in this paper. Glass beads were used to represent sand particles. Three ...
Microbially induced calcite precipitation in calcareous soils by endogenous Bacillus cereus, at high pH and harsh weather
(
Elsevier
, 2020 , Article)
Microbially induced calcite precipitation (MICP) improves the physical properties of soils by increasing the solid content, decreasing the pore sizes and improving the rigidity of the particle-to-particle contact ending ...
Investigating the effect of polymer-modified graphene oxide coating on RO membrane fouling
(
Elsevier
, 2022 , Article)
The development of novel reverse osmosis (RO) membranes resistant to multiple types of fouling is a need to secure clean water production and meet rising water demands. In this paper, the RO membrane surface-functionalized ...
Bayesian network and response surface methodology for prediction and improvement of bacterial metabolite production
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The optimization of antifungal activity production by Bacillus amyloliquefaciens was carried out using Response Surface Methodology (RSM) in two steps. The first step involved the screening of cultural parameters affecting ...
Reuse of Sludge as Organic Soil Amendment: Insights into the Current Situation and Potential Challenges
(
MDPI
, 2023 , Article Review)
Sludge generation as an organic by-product of wastewater treatment has seen a consistent increase worldwide due to population growth and industrial activities. This poses a chronic challenge regarding management options ...
Date pits based nanomaterials for thermal insulation applications - Towards energy efficient buildings in Qatar
(
Public Library of Science
, 2021 , Article)
Air-conditioning systems make the most significant part of energy consumption in the residential sector. There is no denying that it is essential to produce a comfortable indoor thermal environment for residents in a ...
Characterization and assessment of process water from oil and gas production: A case study of process wastewater in Qatar
(
Elsevier
, 2022 , Article)
This study characterized and assessed three different process water (PWWs) (S-1, S-2, and S-3) from oil and gas production in Qatar. The wastewater generated in various processing stages contains many harmful components ...
Evidencing the role of carbonic anhydrase in the formation of carbonate minerals by bacterial strains isolated from extreme environments in Qatar
(
Elsevier
, 2022 , Article)
Calcium carbonate, one of the most abundant minerals in the geological records is considered as primary source of the carbon reservoir. The role of microorganisms in the biotic precipitation of calcium carbonate has been ...
Interaction between indigenous hydrocarbon-degrading bacteria in reconstituted mixtures for remediation of weathered oil in soil
(
Elsevier
, 2022 , Article)
It has been demonstrated that biostimulation is necessary to investigate the interactions between indigenous bacteria and establish an approach for the bioremediation of soils contaminated with weathered oil. This was ...
The use of principle component analysis and MALDI-TOF MS for the differentiation of mineral forming: Virgibacillus and Bacillus species isolated from sabkhas
(
Royal Society of Chemistry
, 2020 , Article)
Occurrence of mineral forming and other bacteria in mats is well demonstrated. However, their high diversity shown by ribotyping has not been explained, although it could explain the diversity of formed minerals. Common ...
