Technical and economic simulation of a hybrid renewable energy power system design for industrial application.

Countries in Africa rank the highest in low energy accessibility and air pollution globally. Presenting the urgent need to explore renewable energy sources to tackle the power challenge and reduce the carbon footprint for a greener atmosphere. A novel hybrid wind and solar renewable energy power system (HREPS) coupled to a battery that is capable of powering industrial appliances in the Basse district of The Gambia has been proposed.

Technical analysis of wind energy potentials using a modified Weibull and Raleigh distribution model parameters approach in the Gambia.

Wind energy has gained prominence over the past few decades because of its environment-friendly nature and abundant availability. However, the exploration of wind energy requires adequate knowledge of the wind distribution parameters before installing the wind turbine. This study assessed the potential of harvesting wind energy at two Gambian locations by fitting the best model comparing Weibull and Raleigh Distributions.

Improved Biogas Production from Human Excreta Using Chicken Feather Powder: A Sustainable Option to Eradicating Poverty.

It has been proposed that providing energy for cooking and lighting would solve over 65% of energy needs in rural communities. The use of biomass resources has been found not sustainable as other bioproducts such as biodiesel and bioethanol depend on it. More so that there is a depletion of bioresources in some parts of the world.

Dataset on effect of sand grain size and water salinity on oil recovery.

This research investigates the combined effect of grain size and water salinity on oil recovery. Water flooding experiment was carried out using unconsolidated formation from Niger Delta. Five groups consisting of five samples, were tested for the effective interaction of two factors (grain size and salinity) and how they affect oil recovery.

Dataset on corrosion degradation behaviour of mild steel in developed nano-cutting coolant from agro waste.

Investigation of the corrosion degradation behaviour of mild steel in an admixture of coconut shell and egg shell (CS-ES) based nano-fluid was presented in this study. Mild steel coupons were immersed in different concentrations (nine concentrations and the control as a reference) of the developed nano-fluid for a period of 24, 48, 72, 96, 120, 144 and 168 h. Corrosion rate was calculated based on ASTM Standard G1-03 standard practice for preparing, cleaning and evaluation of corrosion test specimens.

Green synthesis of triclinic (anorthic) phase AgCoPO nanoparticles: optical studies and theoretical modelling.

We report the plant-mediated synthesis, structural investigation, optical properties and theoretical modelling of a triclinic (anorthic) phase AgCoPO nanoparticles for the first time. As part of green chemistry, the secondary metabolites in the leaf extract of were engaged as the reducing/capping agent for the metal nanoparticles. X-ray diffraction (XRD) revealed the presence of an anorthic AgCoPO phase, crystallised in a triclinic structure with P -1 space group.

Radiological and toxicity risk exposures of oil based mud: health implication on drilling crew in Niger Delta.

Naturally occurring radioactive materials (NORMs) and the presence of toxic metals in drilling fluids/their additives have raised research interests in recent times owing to the risks associated with the exposure times for drillers of petroleum wells. In this study, two drilling fluids A and B were formulated, while two other Mud Samples C and D were obtained from drilled shale and shale-sand formation zones. All four fluids were collected and analyzed for the presence of radioactive and heavy metals.

Loss Path Influence on the MRI Radio Frequency Pulse Sequence: A Theoretical Evidence.

The RF pulse is initiated from either the loop or loopless MRI antenna. It has shown an increased advancement in recent times. Somehow, the concept has proven successful in the MR imaging procedure.

Influence of n-Mosfet transistor on dye-sensitized solar cell efficiency.

A new strategy for evaluating the efficiency of Dye-sensitized Solar Cell (DSC) employed in this study was to introduce a device stabilizer which also functioned as an external load. This aim was accomplished through computations of efficiency of different DSCs based on n-Mosfet transistor. Transistor Z44 mosfet's impact on the DSC systems was to significantly moderate the effect of two vital components namel; the photoanodes and electrolyte sensitizers.

Data on the rheological behavior of cassava starch paste using different models.

Proper selection of rheological models is very important in flow characterization. These models are often used to evaluate parameters that help in the characterization of food samples. Rheological models also provide flow predictions for extreme conditions where the flow nature of the fluid cannot be determined, hence the need for appropriate selection of rheological models.

Modeling and Synthesis of Ag and Ag/Ni Allied Bimetallic Nanoparticles by Green Method: Optical and Biological Properties.

In the quest for environmental remediation which involves eco-friendly synthetic routes, we herein report synthesis and modeling of silver nanoparticles (Ag NPs) and silver/nickel allied bimetallic nanoparticles (Ag/Ni NPs) using plant-extract reduction method. Secondary metabolites in the leaf extract of acted as reducing agent. Electronic transitions resulted in emergence of surface plasmon resonance in the regions of 416 nm (Ag NPs) and 421 nm (Ag/Ni NPs) during optical measurements.

Parametric retrieval model for estimating aerosol size distribution via the AERONET, LAGOS station.

The size characteristics of atmospheric aerosol over the tropical region of Lagos, Southern Nigeria were investigated using two years of continuous spectral aerosol optical depth measurements via the AERONET station for four major bands i.e. blue, green, red and infrared.
