CO₂ Efficiency Break Points for Processes Associated to Wood and Coal Transport and Heating

Energies, 2019
This paper aims to deal with CO2 emissions in energy production process in an original way, based on calculations of total specific CO2 emissions, depending on the type of fuel and the transport distance. This paper has ambition to set a break point from

Freezing by Heating in a Driven Mesoscopic System [PDF]

, 2000
We investigate a simple model corresponding to particles driven in opposite directions and interacting via a repulsive potential. The particles move off-lattice on a periodic strip and are subject to random forces as well. We show that this model - which

Effect of Low Temperature on Electric Vehicle Range

World Electric Vehicle Journal, 2021
A significant disadvantage of battery electric vehicles compared to vehicles with internal combustion engines is their sharply decreased driving range at low temperatures. Two factors are primarily responsible for this decreased range.
