background: placenta previa (pp) is an obstetric complication that can affect maternal and fetal morbidity and mortality. its prevalence is rising due to cesarean sections. there is no quantitative data of placenta in pp. in this study, quantitative parameters of placenta in cases with pp in comparison with normally implanted controls were investigated. methods: in this quasi experimental study...

Transportation of heavy oil by the so-called water-ring technique is a very promising method which pressure drop and pollution can be significantly reduced. Dedicated experiments have been carried out changing phase’s density, viscosity, velocity interfacial tension to systematically analyze characteristics water ring. On basis such experimental data, mathematical model for prediction has intro...

In order to attack the problem of asymmetric shapes of the observed Supernova Remnants, a numerical technique is developed that divides the sphere into many sectors. Using this numerical method, some of the observed features of the supernova remnants, like a barrel shape or multi-ring shape can be reproduced.

BACKGROUND LV diastolic vortex formation has been suggested to critically contribute to efficient blood pumping function, while altered vortex formation has been associated with LV pathologies. Therefore, quantitative characterization of vortex flow might provide a novel objective tool for evaluating LV function. The objectives of this study were 1) assess feasibility of vortex flow analysis du...

Using the complete set of stellar and radio occultation data from Cassini mission, we fit a multimode model to outer edge Saturn’s A ring, similar that previously applied B ring by Spitale Porco (2010) Nicholson et al. (2014a). Our takes into account coorbital libration satellite Janus, whose 7:6 Lindblad resonance is believed be responsible for maintaining at its observed location. Consistent ...
