The flow induced by a liquid column falling on an undisturbed liquid surface is studied with the aid of a high-speed camera. The falling liquid spreads over the receiving liquid forming a cavity which eventually pinches off due to the action of gravity. It is only at this point that the normal flow pattern in which the impacting liquid penetrates below the free surface is established. The same ...

Ink-jet printing combines large-area film fabrication with low-cost solution processing. A high-resolution display calls for small-sized and closely arranged pixels, which can be realised using ink-jet printing. Here, we introduce the relevant steps of printing, namely, droplet formation, falling, hitting substrate, spreading, formation a pixel. On basis summarisation factors that affect pixel ...

We have performed a first fully 3-D GRMHD simulation with Schwarzschild black hole with a free falling corona. The initial simulation results show that a jet is created as in the previous simulations using the axisymmetric geometry with the mirror symmetry at the equator. However, the time to generate the jet is longer than in the 2-D axisymmetric simulations. We expect that due to the addition...

Quantum Chromodynamics predicts radiative terms which, at low transverse momentum QT of an observed multi-particle system, can be large enough to threaten the legitimacy of a fixed-order perturbative treatment. We present a subtraction-style calculation which sums these terms to all orders for a direct photon plus jet final state, and show that the kinematic effect of such a resummation is sign...

Introduction: Dental trauma is a very significant problem in primary dentition. It has a physical, esthetic and psychological impact on the child and his/her parents. The purpose of this study was to assess the prevalence of traumatic inju‌ries to the anterior primary teeth and deter‌mining factors in 2-5-year-old children in Rasht, 2012. Materials and Methods: This research was a cross-sectio...
