In this paper, it is shown completely analytically that a spintessence model in the dust dominated universe can very well serve the purpose of providing an early deceleration and a present day acceleration. The stunning results of the observations on the luminosity redshift relation of some distant supernovae [1, 2], that the universe is currently undergoing an accelerated phase of expansion, p...

Before the onset of a flare is observed in hard X-rays there is often a prolonged pre-flare or pre-heating phase with no detectable hard X-ray emission but pronounced soft X-ray emission suggesting that energy is being released and deposited into the corona and chromosphere already at this stage. This work analyses the temporal evolution of coronal source heating and the chromospheric response ...

The dynamics of an axisymmetric liquid bridge stretch are investigated by means numerical simulations, and the results validated experimentally. constant acceleration lower substrate stretches bridge. A simplified simulation model experimental setup is developed for unstructured volume-of-fluid two-phase flow method, which models as a fluid with prescribed retracting substrate. effect stretchin...
