Cracks in refractory concrete: Transgranular or intergranular?

e-Journal of Nondestructive Testing
We examine refractory concrete samples imaged in situ while undergoing compression. We suggest a method for quantifying the degree of transgranular cracking based on segmenting the aggregate and the crack systems in the computed tomography images.

Maternal Paradox: When Nurturer Meets the Knife, Living Organ Donation From Daughters to Mothers in Türkiye

Sociology Lens, EarlyView.
ABSTRACT This article uses the case of living organ donation from daughters to mothers in Türkiye to examine how maternal subjectivities are constructed, enacted, and transformed within specific cultural contexts. In Türkiye, motherhood is both culturally idealized and politically reinforced as the moral core of womanhood.

Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2010
Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. Sintering is a process which occurs

Stability of Spatio-Temporal Structures in a Lattice Model of Pulse-Coupled Oscillators

, 1996
We analyze the collective behavior of a lattice model of pulse-coupled oscillators. By studying the intrinsic dynamics of each member of the population and their mutual interactions we observe the emergence of either spatio-temporal structures or ...
