Pressure Transient Analysis of Bingham Fluids using Tiab’s Direct Synthesis Approach
(2019-07-23)
This study investigated transient flow response of heavy oil that exhibit Bingham fluid characteristics. Four wellbore conditions in naturally fractured reservoirs were considered which include horizontal well, hydraulically ...
Malaria Prediction using Bayesian and other Machine Learning Techniques
(2019-09-12)
Main purpose of data mining is to extract valuable information from available data. With the enormous amount of data stored in files, databases, and repositories, in the healthcare sector, it’s increasingly important, if ...
Quantifying the Risks of Wellbore Failure during Drilling Operations Using Bayesian Algorithm
(2019-06-23)
The wellbore integrity plays an important role in petroleum operations like drilling, well completion and production. Caliper, Electrical image logs, Acoustic televiewers (ATV) and Optical televiewers (OTV) are some of the ...
Assessment of Heavy Metal Pollution in Soil and Surface Water in Mng-Gold, Kokoya District, Bong County, Liberia
(2019-07-12)
The presence of heavy metals in water and soil by metalliferous mining activities at MNG-Gold Mine was fully investigated. The extraction of gold in recent years, has led to the generation of huge quantities of solid and ...
Investigation of Peo-Polymer Blend Electrolytes for Electrochemical Capacitors
(2019-07-13)
Recently, there has been a drift of attention towards gel polymer based electrolytes owing to the fact that they are cheap and can achieve an extended potential window for improved energy density in s upercapacitor devices ...
First Principles Study of Porous Carbon as Anode Material for Metal-Ion (Na, Li, Mg) Batteries Applications
(2019-06-23)
Sodium-ion batteries (SIBs) have been identified as an effective technology for grid-scale energy storage because of relatively low cost and natural abundance of sodium, but the lack of suitable anode materials with high ...
Bioactive Polymer as an Alternative Binder for Electrochemical Capacitors
(2019-07-13)
Binders are important components of electrodes of supercapacitors because of their ability to adhere active components and make the resultant slurry to adhere on current collectors.
This work seeks to investigate the ...
Investigation of Lead-Free Bismuth Perovskite by Numerical Simulation using Scaps
(2019-06-23)
The theoretical study of methylammonium bismuth halide, (CH 3 NH 3 ) 3 Bi 2 I 9 , was simulated using SCAPS 1D software package. The effect of the bismuth perovskite absorber layer thickness on the solar cell performance ...
First-Principles Density Functional Theory Studies of the Structural and Electronic Properties of Prodigiosin as a Cancer Drug
(2019-06-23)
Prodigiosin molecule, whose efficacy in the treatment of cancer has proven positive, has been studied using first-principles Density Functional Theory (DFT) methods as implemented in VASP - Vienna Ab initio Simulation ...
Design, Construction and Evaluation of Charcoal, Activated Carbon, Moringa Seed and Sand Water Filtration Systems
(2019-06-23)
The majority of human population especially in developing countries suffers from water-borne diseases such as skin abscesses, cellulitis, skin infections, and diarrhoea due to improperly treated water. Safe drinking water ...
