A Thermodynamic‐Kinetic Model for Basic Oxygen Furnace Tapping: Improved Prediction of Phosphorus and Steel‐Slag Evolution

steel research international, EarlyView.
This study develops a thermodynamic–kinetic model for basic oxygen furnace tapping and validates its accuracy under near‐equilibrium and far‐from‐equilibrium initial conditions. Comparison with a reference model demonstrates its broader applicability. The model further reveals the evolution of key steel and slag components, providing new transparency ...

Development of a simulation procedure for the evaluation of new refractories for aluminium furnaces [PDF]

, 2014
Refractory materials for aluminium industry are designed to be resistant to different degrees of thermal, mechanical and chemical wear. The refractory wall thickness reduction during service life increases the heat losses through walls decreasing the ...

Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Was Einhard a widower?

Gender &History, EarlyView.
Abstract The ‘widow’ is a gendered, socially contingent category. Women who experienced spousal bereavement in the early middle ages faced various socio‐economic and legal ramifications; the ‘widow’ was further a rhetorical figure with a defined emotional register. The widower is, by contrast, an anachronistic category.

Cimento aluminoso e seus efeitos em concretos refratários magnesianos espinelizados in situ Calcium aluminate cement and its effects on in-situ spinel containing magnesia refractory castables

Cerâmica, 2010
O uso de concretos refratários alumina-magnésia ligados por cimento aluminoso (CAC) apresenta vantagens decorrentes da presença de espinélio e de CA6 (CaO.6Al2O3), ambas formadas in-situ e acompanhadas de expansão.

Mothers against the natural order: Gender representations and desertion of identities in the drama of disinheriting a son in eighteenth‐century Barcelona  

Gender &History, EarlyView.
ABSTRACT The disinheritance of a firstborn son accustomed to the privileges of exclusion has for centuries been a dramatic event for families, especially if the decision was taken by a woman, the son's own mother. Very few dared to do so, because it symbolised a break with the notion of virtuous, compassionate motherhood; it represented a failure to be
