The kinetics and mechanism of bainite transformation have been studied in Fe-Cr-Mo-V-Ti-C steel high speed dilatometry backed by thermodynamic analysis. The complete transformation of austenite, however, has not occurred at any reported temperature. Obtained results confirm the incomplete reaction phenomenon with the cessation of the bainite transformation well before the paraequilibrium is ach...

While the pulmonary toxicity of NO2 is clearly established, the mechanism by which it is removed from inspired air is poorly understood. Uptake is most likely dependent on chemical reaction since, despite limited per se gaseous NO2 aqueous solubility, uptake proceeds rapidly without ready saturation. We utilized an isolated perfused rat lung model to characterize the effect of dose rate on upta...

this paper was concerned with studying the magnetohydrodynamic steady laminar free convection flow of a micropolar fluid past a continuously moving surface in the presence of heat generation and thermal radiation. similarity transformation was employed to transform the governing partial differential equations into ordinary ones, which were then solved numerically using the finite element method...

We have investigated the increased rate of glycolysis following transformation of chick embryo fibroblasts by Rous sarcoma virus. In both normal and transformed cells the regeneration of adenosine 5 -diphosphate and orthophosphate was found to be the rate-limiting factor for glycolysis. The plasma membrane Na -K -adenosine5 -triphosphatase (ATPase) was a major contributor to adenosine 5 -diphos...

background: a highly efficient genetic transformation system is essential for a successful genetic manipulation of the african violet (saintpaulia ionantha wendl.).objectives: developing a particle bombardment-based genetic transformation system for the african violet.materials and methods: a local cultivar of the african violet from guilan province was used for transformation experiments. the ...
