Strength and Durability Properties of Concrete Containing Pumice and Scoria as Supplementary Cementitious Material
(Hindawi, 2021-05-24)
Concrete structures suffer serious deterioration under a corrosive environment. Consequently, the service life of these concrete
structures is decreased and deteriorates under combined attack of sulphate and chlorides. ...
Integrated Capacitive Deionization and Humidification-Dehumidification System for Brackish Water Desalination
(MDPI, 2021-11-15)
A hybrid capacitive deionization and humidification-dehumidification (CDI–HDH) desalination system is theoretically investigated for the desalination of brackish water. The CDI system
works with two basic operations: ...
Sub- and Supercritical Water Gasification of Rice Husk: Parametric Optimization Using the I-Optimality Criterion.
(ACS Publications, 2021-05-18)
In this study, rice husk biomass was gasified under sub- and supercritical water conditions in an autoclave reactor. The effect of temperature (350-500 °C), residence time (30-120 min), and feed concentration (3-10 wt %) ...
Water Boiling Test of carbonized briquettes produced from charcoal fines using African Elemi (Canarium schweinfurthii) resin as an organic binder
(Springer Nature Switzerland AG., 2021-10-10)
The study evaluated carbonized briquettes produced from charcoal fines using African Elemi (Canarium schweinfurthii) resin as a binder. Briquette samples (B25, B30, B35, B40) with the ratio of charcoal fines:binder of 3:1, ...
Production of carbonized briquettes from charcoal fines using African Elemi (Canarium Schweinfurthii) resin as an organic binder
(Taylor & Francis Group, 2021-09-25)
This study investigated the use of African Elemi (Canarium Schweinfurthii) resin as a binder for the production of carbonized briquettes from charcoal fines. The binder and charcoal fines were characterized through proximate ...
Capacitive deionization: a promising technology for water defluoridation: a review
(IWA Publishing, 2021-08-30)
Capacitive deionization (CDI) is among the promising technologies employed for water purification. CDI has been studied for the removal of
various ionic species from water including fluoride ion (F ) with promising results. ...
A Review on Computational Fluid Dynamics Applications in the Design and Optimization of Crossflow Hydro Turbines
(Hindawi, 2021-10-15)
In recent years, advances in using computational fluid dynamics (CFD) software have greatly increased due to its great potential to
save time in the design process compared to experimental testing for data acquisition. ...
Capacitive Deionization for the Removal of Paraquat Herbicide from Aqueous Solution
(Hindawi, 2021-10-08)
In comparison to other conventional methods like adsorption and reverse osmosis (RO), capacitive deionization (CDI) has only been investigated extensively for the removal of inorganic pollutants from water, demonstrating ...
Clustering and Fuzzy Logic-Based Demand-Side Management for Solar Microgrid Operation: Case Study of Ngurudoto Microgrid, Arusha, Tanzania
(Hindawi, 2021-02-15)
Permanent electricity availability should not be taken for granted since grid sustainability and reliability are at stake when there is no balance between supply and demand. This paper employs a load balancing demand-side ...
Design and Performance Analysis of Composite Airfoil Wind Turbine Blade
(University of Dar es Salaam, 2021)
Small horizontal axis wind turbine rotors with composite airfoil rotor blades were designed and
investigated in the present study in order to improve its performance in low wind speed and low
Reynolds number (Re) conditions ...
