Abstract:

The study aims to pinpoint the moderating role of an aspect of corporate governance, that is, Board Structure, in the relationship between managerial behaviour and firm performance. Using data envelopment analysis (DEA), firm efficiency is measured, and afterward, this firm efficiency is regressed on firm size, market share of the company, business segment and foreign currency translation. The residual values are the measurements of managerial behaviour. The data for 11 years (2009–2019) was collected from 492 non-financial firms listed on the stock exchanges of Pakistan, Bangladesh and India.

Lighter alcohols like ethanol and methanol are easily miscible with gasoline and by blending alcohols with gasoline; a part of conventional fuel can be replaced while contributing to fuel economy. Several researchers tested various ethanol blends on different engine test rigs and identified ethanol as one of the most promising ecofriendly fuels for spark ignition engine. Its properties high octane number, high latent heat of vaporization give better performance characteristics and reduces exhaust emissions compared to gasoline. This paper focuses on studying the effects of blending 50 of ethanol by volume with gasoline as it hardly needs engine modifications. Gasoline (E0) and E50 fuels were investigated experimentally on single-cylinder, four-stroke port fuel injection spark ignition engine by varying engine speed from 1500 rpm to 3500 rpm. Performance Characteristics like torque, brake power, specific fuel consumption, and volumetric efficiency and exhaust emissions such as HC, CO, CO2, NOx were studied..

Ankle Foot Orthosis (AFO) is the medical device which is recommended for the patients to improve the walking ability and decrease the risk of falls. Custom AFOs provide better fit, comfort and performance than pre-manufactured ones. The technique of 3D-printing is suitable for making custom AFOs. Fused deposition modelling (FDM) is a 3D-printing method for custom AFO applications with the desired resistance and material deposition rate. Generally, FDM is a thermal process; therefore materials thermal behaviour plays an important role in optimizing the performance of the printed parts. The objective of this study is to evaluate the thermal behaviour of PLA, ABS, nylon and WF-PLA filaments before manufacturing the AFO components using the FDM method. In the study, the sequence of testing materials provides a basic measuring method to investigate AFO device parts thermal stability. Thermal analysis (TG/DTG and DSC) was carried out before 3D printing is to characterize the thermal stability of each material.

Moreover, energy levels in these deposits are low and need to be elevated by introducing efficient operative conversion technologies to utilize these residues as fuels. In this context, the utilization of a fluidized bed innovation enables a wide range of non-uniform-sized low-grade fuels to be effectively converted into other forms of energy.This study was undertaken to evaluate the effectiveness of fluidized conversion method for transformation of agricultural by-products such as rice husk, sawdust, and groundnut shells into useful energy. The present investigation was conducted to know the mixing characteristics of sand and fuel have been found by conducting experiments with mixing ratio of rice husk (1:13), saw dust(1:5) and groundnut shells (1:12), the variation of particle movement in the bed and mixing characteristics are analyzed. The impact of sand molecule size on the fluidization speed of two biofuel and sand components is studied and recommended for groundnut shells using a sand molecule of 0.6 mm size and for rice husk, sawdust 0.4 mm sand particle size. Also, establish that the particle size of sand has a significant effect on mingling features in case of sawdust. In the next part of the investigation, the CFD simulations of the fluidized bed are done to investigate the mixing behavior of sand and biomass particles. A set of simulations are conducted by ANSYS FLUENT16; the state of the bed is the same as that of the test. The findings were presented with the volume fraction of sand and biomass particles in the form of contour plots.
