Is the solar spectrum latitude dependent? An investigation with SST/TRIPPEL [PDF]

, 2011
Context: In studies of the solar spectrum relative to spectra of solar twin stars, it has been found that the chemical composition of the Sun seems to depart systematically from those of the twins.

Alkali resistance testing methodology and development: Focus on mullite based castables

International Journal of Ceramic Engineering & Science, 2022
Aluminosilicate refractories, which are widely used in alkali‐rich environments, typically have a matrix that is close to mullite in composition. It is the matrix component that is most vulnerable to attack in service.

The Origin of Cosmic Rays: How Their Composition Defines Their Sources and Sites, and the Processes of Their Mixing, Injection and Acceleration [PDF]

, 1976
Galactic cosmic-ray source compositions, (Z/H)GCRS from H to Pb and ~10^8 - 10^14 eV, differ from solar-local interstellar, (Z/H)SS or (Z/H)ISM by ~20-200x.

Advances in the Development, Processing, and Application of Locally Sourced Clay-based Refractory Materials for Furnace Application in Nigeria

Science, Engineering and Technology
Refractories are ceramic materials that are used in high-temperature applications, often above 1100oC. These materials find applications in reactors, kilns, ovens, and furnace linings.

Chemical Equilibrium Abundances in Brown Dwarf and Extrasolar Giant Planet Atmospheres

, 1998
We calculate detailed chemical abundance profiles for a variety of brown dwarf and extrasolar giant planet atmosphere models, focusing in particular on Gliese 229B, and derive the systematics of the changes in the dominant reservoirs of the major ...

Dexamethasone for Chemotherapy‐Induced Nausea and Vomiting Prevention in Pediatric Patients: International Consensus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.

Mechanical properties and microstructure fractal analysis of refractory bauxite concrete [PDF]

Science of Sintering, 2015
The surface topography analysis via fractals as a means of explanation of composite materials mechanical and microstructural characteristics has hardly been reported so far. This study proposes a method of fractal analysis and its application to

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.
