Reading: exploring the reading skill after the second schoolyear in Icelandic children

Frontiers in Education
The main aim of this study was to investigate whether there are gender differences in children’s reading ability at the end of their second year of primary school in Iceland (N = 545; 260 girls, 285 boys, mean age: 7.7 years, SD = 0.39). A second aim was

Burning Velocity for the Compacted Mixture of a Ti-Al System, Just after Spontaneous Ignition in the SHS Process

Journal of Thermal Science and Technology, 2012
Burning velocity just after spontaneous ignition has been examined not only experimentally but also theoretically, as related to a Self-propagating High-temperature Synthesis (SHS) process, for a Ti-Al system.

Numerical investigation of forced ignition in laminar counterflow non-premixed methane-air flames

, 2007
Simulations of forced ignition of non-premixed laminar counterflow flames are used to study the effect of strain rate on ignition success. A one dimensional calculation is performed, using detailed methane chemical kinetics and treating the spark as an ...

A Critical Analysis of the Oxy-Combustion Process: From Mathematical Models to Combustion Product Analysis

Energies, 2022
Fossil fuels are the most widely used resource for energy production. Carbon dioxide (CO2) emissions are correlated with climate change, and therefore these emissions must be reduced in the future.

Gas-phase and heat-exchange effects on the ignition of high- and low-exothermicity porous solids subject to constant heating

, 2006
This article investigates the ignition of low-exothermicity reactive porous solids exposed to a maintained source of heat (hotspot), without oxygen limitation.

The effect of oxygen starvation on ignition phenomena in a reactive solid containing a hot-spot [PDF]

, 2003
In this paper, we explore the effect of oxygen supply on the conditions necessary to sustain a self-propagating front from a spherical source of heat embedded in a much larger volume of solid.
