Background: Advances in neonatal intensive care have markedly improved survival in preterm infants. These babies need hospitalization due to the immaturity of the respiratory and digestive systems. The timing for the initiation of proper feeding in premature infants admitted to neonatal intensive care units (NICUs) is an important challenge for physicians, parents, and...

Background: This study was targeted toward comparing volume-guaranteed (VG) ventilation with conventional pressure-controlled (PC) ventilation in preterm infants with respiratory distress syndrome (RDS) in terms of the facilitation of weaning and extubation and occurrence of complications, such as pneumothorax, intraventricular hemorrhage (IVH), retinopathy of prematur...

In this paper we develop the principles of time-delayed control design for the active control of structures in which the presence of large time delays in the control loop may make it difficult for their effects to be easily eliminated and/or compensated. A control design strategy is proposed that is different from what has been generally accepted hereto; it calls for taking advantage of these l...

Strong motion recordings from four seismically isolated buildings are used in time-invariant and time-variant modal identification analyses. The buildings are identified as equivalent, time-varying, linear dynamic systems characterized by their time-varying modal parameters (including fundamental-mode natural frequencies, damping ratios, and mode shapes). The identification analyses for each si...

the purpose of this paper is to provide some asymptotic results for nonparametric estimator of the lorenz curve and lorenz process for the case in which data are assumed to be strong mixing subject to random left truncation. first, we show that nonparametric estimator of the lorenz curve is uniformly strongly consistent for the associated lorenz curve. also, a strong gaussian approximation for ...

Background: Mental disorders are generally a significant reason for increased morbidity. They constitute a serious disease burden. One of the main reasons for this disease burden is long hospitalization periods. Objective: The current study investigated the length of hospital stay and the variables affecting it in patients treated in the Gazi University H...

objective: application of chemical solvents especially in problematic canals is usually a part of the retreatment process.this study was performed to compare the solubility of gutta- percha and resilon in chloroform and to find the effect of sample thickness as well as the time of shaking on their solubility. materials and methods: specific weight of resilon and gutta-percha was placed in a sam...

This study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% Pb, 1.91% Zn taken from Changarzeh mine, South Natanz, Iran. The effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, pH and solid content were investigated in relation t...
