Effects of ambient temperature on the combustion processes of single pulverized coal particle

open access: yesJournal of Thermal Science and Technology, 2021
In the pulverized coal combustion, coal particles cross over a steep temperature gradient formed by a diffusion flame. This temperature gradient affects the particle temperature. This study has experimentally investigated effects of field temperature and

Aid, Volatility, and Growth Again: When Aid Volatility Matters and When it Does Not [PDF]

open access: yesReview of Development Economics, 2009
AbstractIn previous papers the authors have argued that aid is likely to mitigate the negative effects of external shocks on economic growth (i.e. that aid is more effective in countries which are more vulnerable to external shocks). Recently an important debate has emerged about the possible negative effects of aid volatility itself.

Investigation of the Laser Radiation Effects on Lignite with the Products Analysis by Mass Spectrometry

open access: yesEurasian Chemico-Technological Journal, 2020
In this paper, one studied the effect of pulsed laser radiation (1064 nm, 120 μs) on lignite. The method of mass spectrometry was used to analyze the formed gaseous reaction products after the exposing of coal samples to the laser radiation.
