This coincides with the previous condition of transversal patterns to emerge in stationary fronts [PePeC/T<1 [Viswanathan, G., Bindal, A., Khinast, J., Luss, D., 2005. Stationary transversal hot zones in adiabatic packed-bed reactors. A.I.Ch.E.
Stationary, oscillating- and travelling axial-pulses are shown to emerge, in agreement with the experimentally observed axial patterns, and simulations, backed by linear analysis, show that transversal patterns may emerge as well.
We show that a moving-front solution in a cylindrical shell packed-bed catalyzing a first-order activated reaction may bifurcate into transversal patterns when PePeC/T<ΔTad/ΔTm, i.e. when the ratio of the mass to heat Pe numbers is smaller than the ratio of the adiabatic to maximal temperature rises.
In rostrocaudal sections of adult thoraces, a neat signal with a regular transversal banding pattern spanning throughout the IFM fiber width was observed (Fig. 6C).
Nevertheless the transversal design of this study prevents detecting neither acquisition patterns of more than one HPV type nor its relationship with the different risk factors, which make it relevant to conduct longitudinal studies to detect the moment when the acquisition of other HPV types occur and determine if infection events take place simultaneously.
This study was carried out using a transversal design.
This is an economic study with a transversal design.
The phase profiles we propose can be combined with multiple transversal foci phase patterns to actually form axial replicas of the transversal foci.
This work analyses the possible axial- and transversal thermal spatio-temporal patterns that may emerge in a two-dimensional thin annular catalytic bed model using a detailed micro-kinetic model for CO oxidation.
Study design: Transversal cohort.
