Investigation on the Alloy Mixing and Inclusion Removement through Using a New Slot-Porous Matched Tuyeres

open access: yesMetals, 2023
A mathematical model was developed to investigate the refining process through using slot-porous matched dual tuyeres. In this model, the bubble expansion is considered through the ideal gas state equation.

Effect of Batch-Annealing Temperature on Oxidation of 22MnB5 Steel during Austenitizing

open access: yesMetals, 2023
In this paper, the effect of batch-annealing temperature on the oxidation of 22MnB5 steel during austenitizing was studied. When the batch-annealing temperature was decreased from 690 to 680 °C, the surface roughness of cold-rolled 22MnB5 steel decreased,

THE IRON CAGE REVISITED:

open access: yesThe New Economic Sociology, 1983
Instead of examining why organizations are dissimilar, this study explores why organizations tend to be increasingly and inevitably homogenous in their forms and practices.

Stability Analysis of Turing Patterns Generated by the Schnakenberg Model [PDF]

open access: yes, 2004
We consider the following Schnakenberg model on the interval (−1, 1): ut = D1u − u + vu2 in (−1, 1), vt = D2v + B − vu2 in (−1, 1), u (−1) = u (1) = v (−1) = v (1) = 0, where D1 > 0, D2 > 0, B>0.

Iron [PDF]

open access: yesThe Journal of Nutrition, 2001
The most useful and appropriate methods for assessing the bioavailability of (nonheme) iron supplements are described. When the supplement can be labeled isotopically, the best method for measuring bioavailability is hemoglobin incorporation, followed by fecal monitoring. Caco-2 cell in vitro systems can be used for rapid screening to predict potential
