Assessing Land Use/Cover dynamics of the Ngorongoro world heritage site in Tanzania using a hybrid CA–Markov model
(Authorea, 2020-10)In this study, land-use/cover pattern of the UNESCO world heritage site, Ngorongoro Conservation Area; is analyzed using the CA–Markov model with the help of RS and GIS. Hybrid classification techniques ware used to monitor ... -
Assessment of fluoride removal in a batch electrocoagulation process: A case study in the Mount Meru Enclave
(Elsevier B.V., 2021-03-04)The presence of excessive amounts of fluoride than prescribed standards has been reported in various sources of domestic water supply around the slopes of Mount Meru and other parts in Tanzania. Efforts to remove the ... -
Assessment of Groundwater Quality under Changing Climate in Ngorongoro Conservation Area, Tanzania
(American Society of Civil Engineers, 2022-07)Understanding the hydrochemical composition of water resources in the Ngorongoro Conservation Area (NCA, Dodoma, Tanzania) related to climate variability is essential for sustainable development. Thus, the current study ... -
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 ... -
Catalytic hydrothermal liquefaction of orange peels into biocrude: An optimization approach by Central Composite Design
(Elsevier B.V., 2023-06-01)Global instability, persistent increase in pump-price, inflation and depletion of fossil fuel resources amidst the continuous discharge of greenhouse gases from fossil fuels combustion call for urgent attention. The ... -
Characterization of bird, reptile, and insect community diversity in constructed wetlands and waste stabilization ponds across Tanzania
(Elsevier, 2023-11)Wastewater treatment systems, such as Constructed Wetlands (CWs) and Waste Stabilization Ponds (WSPs), have untapped biodiversity enhancement and development potential. Birds, insects, and reptiles, which are displaced by ... -
Characterization of Polycaprolactone and Rice Husk Silica Composite (PCL-SiO2) by E-Spinning to Apply Supporter for Drug Release
(IOP Publishing Ltd, 2017)Abstract. Polycaprolactone (PCL) is an interesting material to apply biomedical field owing to its biodegradability and biocompatibility which is suitable for a specific site with longer healing times. Blending the polymer ... -
Chitosan-coated liposomes of Carrisa spinarum extract: synthesis, analysis and anti-pneumococcal potency
(ICE Publishing, 2023-02-16)In the present study, a chitosan (CS)-coated liposome (LipCsP-Chitosan) nanocarrier was fabricated for the delivery of Carissa spinarum (CsP) polyphenols to improve bioavailability and anti-pneumococcal potential against ... -
Clay-based ceramic materials for water de-fluoridation
(NM-AIST, 2021-08)Long-term consumption of water with fluoride concentration above the WHO recommended limit of 1.5 mg/g may cause fluorosis. Low-income communities living in fluoride endemic regions are more affected as they cannot afford ... -
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 ... -
