Optimal water quality pollution control comes from locating critical nonpoint source pollution areas within a watershed and applying site-specific conservation practices. However, management decisions are implemented at the farm-level. While site-specific conservation practices are crucial for environmental protection, reduction strategies must have economic benefit to the producer if they are ...
N atural gas (NG) is a clean-burning alternative fuel with a significant potential for reducing harmful emissions, especially those of fine particles, from vehicles. Vehicular particulate emissions in turn are a concern, because they are small (small particles are especially harmful to health) and numerous, and occur near ground level where people live and work. In response, some have argued fo...
Simultaneous imaging of depolarized and polarized Rayleigh scattering combined with OH-LIF and two-photon CO-LIF provides two-dimensional measurements of mixture fraction, temperature, scalar dissipation rate, and the forward reaction rate of the reaction CO+ OH = CO2 + H in turbulent partially premixed flames. The concept of the three-scalar technique for determining the mixture fraction using...
Abstract This paper investigates CO 2 intensity changes from energy use in the Nigerian economy for a period of 39 years (1981-2019) using Logarithmic Mean weight Divisia Index (LMDI). The respective contribution and impacts different factors such as activity effects, conversion efficiency, energy, fuel mix, among others on aggregate carbon emission has been examined bearing mind poor electrici...
Residential energy consumptions of both electricity and fuels are associated with emissions of many air pollutants. Temporally and spatially resolved energy consumption data are scarce in China, which are critical for a better understanding of their environmental impacts. In this study, a space-for-time substitution method was proposed and two models for predicting fuel and electricity consumpt...
Compressed natural gas (CNG) is a substitution of alternative fuel for automotive application with significant environmental advantages as it is the only fuel cheaper than gasoline or diesel, comparatively lower air pollution emissions, lesser CO2 emissions. However, emission of methane is 40% more in CNG fuelled engines compared to gasoline and diesel. With the exponential growth in CNG fuelle...
INTRODUCTION The limited availability of fossil fuel sources, worldwide rising energy demands and anticipated climate changes attributed to an increase of greenhouse gasses are important driving forces for finding alternative energy sources. One approach to meeting the increasing energy demands and reduction of greenhouse gas emissions is by large-scale substitution of petrochemically derived t...
