Influence of lithium carbonate and superplasticizer as admixtures on low calcium dialuminate cement castable submitted to thermal shock

Journal of Asian Ceramic Societies, 2021
The purpose of this study was to investigate the hot properties of low calcium dialuminate cement castable as binder with varying amount of Li2CO3 and castament FS20 superplasticizer as admixtures. Thermal damage test was carried out through quenching in

Improved Outcomes for Older Children, Adolescents, and Young Adults With Neuroblastoma in the Post‐Immunotherapy Era: An Updated Report From the International Neuroblastoma Risk Group

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background We describe clinical and biologic characteristics of neuroblastoma in older children, adolescents, and young adults (OCAYA); describe survival outcomes in the post‐immunotherapy era; and identify if there is an age cut‐off that best discriminates outcomes.

Influência dos aditivos sobre a permeabilidade e a velocidade de secagem de concretos refratários aplicados por projeção Influence of additives on the permeability and drying behavior of wet shotcrete refractory castables

Cerâmica, 2004
A projeção a úmido de concretos refratários consiste em aplicar o material como um jato de "spray" sobre a superfície, resultando numa elevada taxa de instalação e uma eficiente compactação do material.

Surface treatment of an Al2O3-based refractory with CO2 and high power diode lasers for improved mechanical and chemical resistance characteristics [PDF]

, 2002
Within both normal and corrosive (NaOH and HNO3) environmental conditions, the wear rate and wear life characteristics of an Al2O3-based refractory were greatly enhanced by means of CO2 and high power diode laser (HPDL) surface treatment.

Clinical Characteristics and Prognostic Risk Factors for Pediatric B‐Cell Lymphoblastic Lymphoma: A Multicenter Retrospective Cohort Study for China Net Childhood Lymphoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background B‐cell lymphoblastic lymphoma (B‐LBL) represents a rare variety of non‐Hodgkin lymphoma, with limited research on its biology, progression, and management. Methods A retrospective analysis was performed on the clinical characteristics of 256 patients aged ≤18 years who received treatment under the China Net Childhood Lymphoma (CNCL)‐

Use of dilatometer to screen refractory raw materials

International Journal of Ceramic Engineering & Science, 2022
Sudden shortage of a particular raw material due to freight disruptions, competitive market, and COVID restrictions have frequently forced the refractory industry to rapidly develop alternative formulations using available low‐cost materials.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Magnesia‐carbon refractories from recycled materials

International Journal of Ceramic Engineering & Science, 2022
Recycling of used refractories – in particular closed‐loop recycling – gains in importance because of both ecological and economic benefits, such as the conservation of natural resources, reduced landfilling, and the reduction of greenhouse gases and ...

Predicting the frequencies of diverse exo-planetary systems

, 2007
Extrasolar planetary systems range from hot Jupiters out to icy comet belts more distant than Pluto. We explain this diversity in a model where the mass of solids in the primordial circumstellar disk dictates the outcome. The star retains measures of the
