Bioremediation of mortar made from Ordinary Portland Cement degraded by Thiobacillus thioparus using Bacillus flexus
(Heliyon, 2021-06)
Cement is widely used as a construction material in the construction industry. However, there are challenges
affecting its durability efficacy. Cement mortar/concrete is subject to degradation by aggressive ions such ...
Heavy metal concentrations in soil and vegetables irrigated with sewage effluent: A case study of Embu sewage treatment plant, Kenya
(Elsevier, 2020-02)
As a result of the increasing constraint in the availability of fresh water for irrigation,
wastewater especially sewage effluent is being used for irrigation of agriculture fields, par-
ticularly in urban and peri–urban ...
A Review on Pyroprocessing Techniques for Selected Wastes Used for Blended Cement Production Applications
(Hindawi, 2020-08)
Pyroprocessing is an important stage in cement manufacturing. In this process, materials are subjected to high temperatures so as
to cause a chemical or physical change. Its control improves efficiency in energy utilization ...
Characterization of Local Nano-Heat Transfer Fluids for Solar Thermal Collection
(Hindawi, 2020-08)
Performance of organic oils in solar thermal collection is limited due to their low thermal conductivity when they are compared to
molten salt solutions. Extraction of organic oils from plants can be locally achieved. 'e ...
Energy recovery from biomethanation of vinasse and its potential application in ozonation post-treatment for removal of biorecalcitrant organic compounds
(ELSEVIER, 2020-10)
Vinasse is characterized by a high chemical oxygen demand (COD) and dark brown colour, which requires abatement before disposal to prevent the pollution of receiving streams. Anaerobic digestion (AD) usually applied for ...
Malaria vector control strategies. What is appropriate towards sustainable global eradication?
(ELSEVIER, 2020-10)
Malaria a mosquito-borne disease caused by Plasmodium remains to be a main global burden despite concerted efforts to eliminate it. While diverse control strategies have been put in place for mosquito-borne diseases, vector ...
Characterization of composite material from the copolymerized polyphenolic matrix with treated cassava peels starch
(Heliyon, 2020-07)
Conventional binders in the particleboards formulation involve use of formaldehyde resins. Epidemiologic studies
show that formaldehyde is carcinogenic. Efforts to reduce formaldehyde emissions by use of scavengers has ...
Crop residues used as lignocellulose materials for particleboards formulation
(Heliyon, 2020-09)
Efforts to reduce pressure on use of wood in particleboard formulation have included the use of non-wood materials such as crop residues. Physical and mechanical properties are determined by the number of the hydroxyl
(-OH) ...
Effect of Bacillus cohnii on Some Physicomechanical and Microstructural Properties of Ordinary Portland Cement
(Hindawi, 2020-09)
Cement-made materials face durability and sustainability challenges. (is is majorly caused by the presence of cracks. Cracking
affects the mechanical strength of cement-based materials. Microbiologically induced calcite ...
