Performance analysis of standalone solar PV panel: case study of Arusha, Tanzania
(NM-AIST, 2019-03)
The purpose of this study was to carry out experimental and theoretical performance analysis of standalone solar Photovoltaic (PV) panel in tropical region. The study concentrated on the influence of poor PV panel positioning ...
Cryptogamic Packed Biofilter as Potential Adsorbent for CO2, NH3, and H2S Impurities from Biogas
(Hindawi, 2020-07-07)
The presence of elevated concentrations of carbon dioxide, hydrogen sulfide, ammonia, and trace impurities in biogas affect its caloric value as well as causes corrosion and is extremely toxic. There are various methods ...
Qualitative soil moisture assessment in semi-arid Africa – the role of experience and training on inter-rater reliability
(Copernicus Publications, 2015-08-10)
Soil and water management is particularly relevant in semi-arid regions to enhance agricultural productivity. During periods of water scarcity, soil moisture differences are important indicators of the soil water deficit ...
Inhibition of aluminium corrosion using carica papaya extracts in acidic media (sulphuric acid and phosphoric acid)
(NM-AIST, 2017-12)
Corrosion inhibition of aluminium using Carica papaya leaves extracts in 1M H2SO4 and IM H3PO4 was investigated under different temperatures (30, 40 and 500C) and concentrations (from 20-100 v/v %). The inhibitor was found ...
Demand-SideManagement of Solar Microgrid Operation: Effect of Time-of-Use Pricing and Incentives
(Hindawi, 2020-06-05)
Over 17% of the world’s population lack access to electricity, the majority being in rural areas of sub-Saharan Africa and South
Asia. Microgrid technologies are a promising solution towards rural and remote area ...
Theoretical study of structure, vibrational spectra and thermodynamic properties of cluster ions existing in vapours over barium dihalides
(NM-AIST, 2017-12)
Computational and theoretical methods were employed to study the structure, vibrational spectra and thermodynamic properties of cluster ions that were detected earlier in saturated vapour over barium dihalides. The equilibrium ...
Biogas slurry derived mesoporous carbon/metal oxides composites for supercapacitors application
(NM-AIST, 2017-12)
With the increasing utilities of intermittent renewable energies, hybrid electric vehicles and portable
electronic devices, supercapacitors have been identified as one of the solution for energy storage
since they can ...
Modelling of energy demand and supply patterns in Tanzania
(2016-04)
Energy is an important element in realizing the interrelated socio-economic development of countries. In an attempt to develop long term energy demand and supply patterns that would enable the country meet her growing ...
Removal of hydrogen sulfide from biogas using sweet potato’s leaves derived activated carbon
(NM-AIST, 2020-04)
Hydrogen sulfide gas contained in biogas is both corrosive and poisonous. In this study a
performance of sweet potato leaves activated carbon for hydrogen sulfide removal from biogas
was evaluated. The samples were ...
Application of rice and corn husk biochar for removal of heavy metal ions from industrial wastewater
(NM-AIST, 2020-01)
This study investigated the removal of heavy metal ions from industrial wastewater by using rice
and corn husk biochar. The choice of the materials was influenced by their largest surface area,
plentiful functional groups ...
