Influence of Starkeya novella on Mechanical and Microstructural Properties of Cement Mortars
(Hindawi, 2020-04)
Cement-based materials are subject to degradation during their service life. Most of the structural failures have been associated with corrosion of the rebar due to chloride ingress, alkali aggregate reaction, and/or sulfate ...
In vitro anti-cancer efficacy and phyto-chemical screening of solvent extracts of Kigelia africana (Lam.) Benth
(Heliyon, 2020)
Background and objectives: Kigelia africana is a medicinal plant growing naturally in many parts of Africa. In Kenya,
a water concoction of the plant is used to treat breast and prostate cancers. Laboratory data on its ...
Biocementation Influence on Flexural Strength and Chloride Ingress by Lysinibacillus sphaericus and Bacillus megaterium in Mortar Structures
(Hindawi, 2020-05)
The concrete/mortar durability performance depends mainly on the environmental conditions, the microstructures, and its chemistry. Cement structures are subject to deterioration by the ingress of aggressive media. This ...
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) ...
