conclusions in our center, prolonged length of stay in the icu correlated positively with euro score. the overall predictive performance of euro score is acceptable and provides both surgeons and intensivists with a good estimate of patient risk in terms of icu stay. background risk stratification models allow preoperative assessment of individual patients cardiac surgical risk and enable analy...

Minimizing the total wire length is an important objective in VLSI layout design. In this paper we consider the problem of minimizing the total wire length during I-dimensional (I-D) compaction. Assume we are given a layout. containing nh horizontal wires, nlJ vertical wires, and rectilinear polygonal layout. components c.omposed of 7lr vertical edges. We present an O(n/, ·nlogn) time algorithm...

OBJECTIVE To evaluate diagnostic value of vaginal pH and cervical length measurement in the second trimester of pregnancy as a preterm labor (PTL) predictor. METHODS During a prospective cohort study 438 uncomplicated singleton pregnant women between 18 and 24 weeks of gestation were assessed regarding vaginal PH and cervical length. Vaginal pH was measured using Ph-indicator strips and cervi...

multiphase flows are commonly encountered in oil and gas industries. the transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the baker chart. the effects of small downward inclinations of ...

PURPOSE To compare the course and magnitude of change on the horizontal and vertical meridians of the cornea after 5 different incisions for cataract: extracapsular cataract extraction (ECCE), 6 mm superior scleral tunnel (6Sup), 3 mm superior scleral tunnel (3Sup), 3 mm temporal scleral tunnel (3Temp), and 3 mm temporal corneal incision (3Cor). METHODS Retrospective chart review of 665 cases...

Thresholds for discriminating the orientation of unreferenced horizontal and vertical lines were measured in subjects with congenital nystagmus (CN) and normal observers and compared to the variability of torsional eye position. Orientation thresholds were determined for horizontal and vertical lines between 0.7 degrees and 5.6 degrees in length, that were presented binocularly for 20-1280 ms. ...

In spite of being one of the most elementary visual effects, the vertical-horizontal illusion is still poorly understood. We provide here a simple quantitative model to describe the overestimation of the vertical segment relative to the horizontal one. The model also includes a necessary factor related to the effect of bisecting a line on the under-estimation of its length. These two factors, o...

Current weather indifferent fields of science and engineering research purposes and different applications are studied. One of the applications of climate studies, the study of the flow over the weir dam and lower exhaust tunnel is aimed at preventing the risk of cavitations. Aeration is known as one of the most economical and practical way to deal with cavitations on rapid spill ways. In the s...
