Defect Analysis and Productivity Enhancement of Crankcase Casting through Pareto Analysis, POKAYOKE and QC Tools

Abstract: Productivity is a very important aspect in any organization. Productivity means output obtained with respect to how much input is provided. To increase the productivity of any organization it is necessary to study and analyze the rejection data of that organization. This research focuses on the need of following a proper methodology in solving any particular problem. The defects were prioritized using QC tools, Pareto analysis. This research emphasizes on the importance of focusing ...

Surface Roughness and Electrochemical Performance Properties of Biosynthesized α-MnO2/NiO-Based Polyaniline Ternary Composites as Efficient Catalysts in Microbial Fuel Cells

In this study, biosynthesized α-MnO2/NiO NPs and chemically oxidative polyaniline (PANI) were synthesized to form ternary composite anode material for MFC. The synthesized materials were characterized with different materials (UV-Vis, FTIR, XRD, TGA-DTA-DSC, SEM-EDX-Gwyddion, CV, and EIS) to deeply examine their optical, structural, morphological, thermal, roughness, and electrocatalytic properties. As a result, the bioelectrical activity of α-MnO2/NiO/PANI composite-modified PGE was ve...

Biosynthesized α-MnO2 -based polyaniline binary composite as efficient bioanode catalyst for high-performance microbial fuel cell

Microbial fuel cell (MFC) has novel technological advances in simultaneous power generation and wastewater treatment applications. In this study, low-cost biosynthesizedα-MnO2 nanoparticles integration with conducting polyaniline (PANI) matrix to form α-MnO2/PANI hybrid nanocomposite was fabricated by in situ polymerization method. The prepared material was characterized through UV-Vis spectroscopy, XRD, FTIR, TGA-DTA, DSC, SEM, cyclic voltammetry, and impedance spectroscopy. MFC perfor...

Advancements in Bioelectricity Generation Through Nanomaterial-Modified Anode Electrodes in Microbial Fuel Cells

The use of nanotechnology in bioelectrochemical systems to recover bioelectricity and metals from waste appears to be a potentially appealing alternative to existing established procedures. This trend exactly characterizes the current renewable energy production technology. Hence, this review focuses on the improvement of the anode electrode by using different functional metal oxide-conducting polymer nanocomposites to enhance microbial fuel cell (MFC) performance. Enhancement of interfa...

Gas Flaring in Nigeria: What Can be Done to Curb It by Cynthia Ohaeri

GAS FLARING in Nigeria, the burning of natural gas associated with oil extraction, has been a prevalent practice. Natural gas brought to the surface, especially where there is no infrastructure to put this “associated gas” to productive use is burnt for disposal thus making it a wasteful and generally polluting practice. An economy that promotes carbon emission through flaring wastes valuable energy products, increases health disparities and fuels climate change, a far-cry from the Glob...

Multi‑time Scale Coordinated Optimization of New Energy High Permeability Power System Considering Flexibility Requirements

The high proportion of grid-connected intermittent energy such as wind power and photovoltaic makes the demand for power system flexibility increase sharply. In order to improve the overall flexibility of new energy high permeability system and enhance the economy of power system, promote the new energy consumption of system. This paper presents a multi- time scale Coordinated optimization strategy for the new energy high permeability power system considering flexibility requirement (MTS...

Root Chip for Growth and Imaging of Arabidopsis Plants

  We describe a microfluidic platform that can be used to study the hydroponic growth of Arabidopsis plants with high-resolution visualization of root development and root-pathogen interactions. The platform comprises a set of parallel microchannels with individual input/output ports, where 1-day old germinated seedlings are initially placed. Under optimal conditions, a root system grows in each microchannel and its images are recorded over a 198-h period. Different concentrations of plant g...

Magnetic Field effects on Saccharomyces cerevisiae for fermentation in bioethanol production

In this study, two sets of experiments were conducted in order to investigate the impact of static magnetic fields on the growth and ethanol production of Saccharomyces cerevisiae. The first experiment ran for 25 hours with a 2% dextrose loading rate, while the second ran for 30 hours with a 6% dextrose loading rate. The magnetic fields used were homogeneous and non-homogeneous, with strengths of 100 mT and 200 mT, respectively. The results showed that the homogenous magnetic field had no sig...

Simplified and Cost-Effective Method of Studying the Effect of Steel Fibers on Ultra-high Performance Concrete Specimens’ Properties/Members’ Performance

This research work, which presents a simplified technique of modelling steel fibers, uses python algorithm that can be directly run in ABAQUS to automatically generate the location and orientation of steel fibers in a rectangular ultra-high performance concrete specimen, so that the effect of steel fibers on the properties of such a specimen can be directly investigated through numerical simulation. This method is fast, can be applied to structural members of bigger dimensions (like beams,...

Determination of Optimum Design Parameters of Non-linear Damped Outrigger System for High-rise Buildings

In addition to the inherent advantages of an outrigger system over conventional framed structural system, damped-outrigger systems (DOS) enhance it further with its agility to resist lateral loads in high-rise buildings. Dynamic response of slender and flexible buildings with DOS induces vibration control in which twisting of core structure is restricted by shear deformation of the damper present at the end of outrigger connected by perimeter columns. In this paper, a 300 m tall core-tube typ...

Evaluation of Voltage Stability of Transmission Line with P-V and V-Q Curved Analysis

ABSTRACT: The inconsistency present in Transmission line tends to have a cascading collapse and different  types of failures in the transmission line of a power system which impact the power transfer capability of the line. In this paper we used MATLAB coding to plot the real power and reactive power with voltage. We want to predict what happens to the stability of a power system before a cascading collapse.  Note: The MATLAB code was intentionally added to this work to serve as a base for...
