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.

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.

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for
