Novel pyrrolo[2,3-d]pyrimidines 5a–j, 6a–j and pyrrolo[2,3-b]pyridines 7a–h; incorporating the common vicinal diaryl motif of tumor necrosis factor-α (TNF-α) inhibitors, were synthesized starting from 2-amino-pyrrole-3-carbonitriles 1a–h. The structures of synthesized compounds were elucidated by spectral data (IR, NMR, and MS) and elemental analyses.(More)
The purpose of the present study is to demonstrate the numerical accuracy of different turbulent models that can predict the physical properties and physical phenomena of turbulent gas flow in a solid rocket nozzle. The nozzle is assumed to have a convergent-divergent geometry with impermeable and adiabatic walls. The entrance flow is subsonic with known(More)
