Fly Ashes for HVFAC Production

Procedia Engineering, 2013
AbstractDevelopment and application HVFAC in the Czech Republic is no easy task. For production HVFAC are important raw materials. especially the quality and characteristics of the ash, which is used for the production HVFAC. The article compares selected chemical and physical properties of Czech fly ashes by foreign fly ash.

Data‐Driven Insights into Rare Earth Mineralization: Machine Learning Applications Using Functional Material Synthesis Data

Advanced Intelligent Systems, EarlyView.
Hydrothermal synthesis records for rare‐earth compounds are repurposed to learn mineralization rules. An extreme gradient boosting model ingests precursors, additives, and engineered descriptors to predict product phases, crystallization temperature, and pH. Feature importance indicates dominant thermodynamic control with kinetic modulation, suggesting

Engaging and strengthening youth through international community‐based research: Implementation and evaluation of an International Youth Advisory Board

American Journal of Community Psychology, EarlyView.
Abstract Youth advisory boards are ubiquitous in community‐based research, yet there is limited description of their development or direct benefits to participants within international research contexts. This convergent mixed‐method study describes and evaluates the design and implementation of a bilingual International Youth Advisory Board (IYAB) of ...

Cuneiform Nucleus Stimulation Can Assist Gait Training to Promote Locomotor Recovery in Individuals With Incomplete Tetraplegia

Annals of Neurology, EarlyView.
Objective Impaired ability to induce stepping after incomplete spinal cord injury (SCI) can limit the efficacy of locomotor training, often leaving patients wheelchair‐bound. The cuneiform nucleus (CNF), a key mesencephalic locomotor control center, modulates the activity of spinal locomotor centers via the reticulospinal tract.

A proximodistal gradient in bone structure and mechanics in the wings of Seba's short‐tailed bat, Carollia perspicillata

The Anatomical Record, EarlyView.
Abstract Bats possess the remarkable ability to fly, and with this, distinctive wing bone properties. We investigated the structural, mechanical, and compositional properties of the humerus, radius, metacarpals, and proximal and middle phalanges of Carollia perspicillata, an approximately 15 g fruit‐eating bat native to the Neotropics.

Improving Fly Ash Whiteness and the Influence of Modified Fly Ash on the Physical Strength of Paper

BioResources, 2015
In order to improve the whiteness of fly ash, the particles were coated by in-situ precipitation of calcium carbonate. After different mass ratios of calcium oxide to fly ash were mixed into water, a certain amount of carbon dioxide was bubbled into the ...
