A 76-year-old, 148-cm woman was scheduled for right upper lobectomy. A 32 Fr left-sided double lumen tube was placed using a conventional technique. Despite several attempts under fiberoptic bronchoscope-guidance, we could not locate the double lumen tube properly. We thus decided to proceed with the bronchial tube in the right mainstem bronchus. During surgery, 8-cm-long laceration was noted o...

The PANDA collaboration intends to build a state-of-the-art detector to study the physics of antiproton annihilation in the charm mass region at the future FAIR facility at GSI, Darmstadt. One major part of the PANDA detector is the straw tube tracker. It will consist of about 6000 individual straws grouped in 11 double layers and filled with an Ar+10% CO2 gas mixture. The required radial spati...

In this paper, a novel foam-filled double ellipse tube (F-DET) is proposed. First, the circle and ellipse tubes with three different configurations(hollow, foam-filled, double foam-filled) are investigated under axial and oblique impact by using the nonlinear finite element code LS-DYNA. The numerical results showed that the F-DET tube has the best crashworthiness performance than tubes with ot...

Abstract In this study, based on the energy balance for different components of a double-layered vacuum-tube solar collector with U-tube, thermal performance unit is investigated separately using an analytical and quasi-dynamic method. The model used in study determines temperature distribution longitudinal radial directions. research, effects physical parameters heat transfer including size co...

OBJECTIVE The objective of this study was to evaluate a novel method of distal end-tidal CO2 capnography by comparison with PaCO2 and with the more standard method that measures mainstream proximal end-tidal CO2 in intubated infants. METHODS Included in the study were all infants who were ventilated with conventional mechanical ventilation and intubated with a double-lumen endotracheal tube i...

tube and pelle are two of the maternally transcribed genes required for dorsal-ventral patterning of the Drosophila embryo. Females homozygous for strong alleles of tube or pelle produce embryos that lack all ventral and lateral embryonic pattern elements. By analyzing the phenotypes caused by 24 pelle and 9 tube alleles, we have defined characteristic features of the two genes, including the e...

During insertion of the double lumen tube in patients with ankylosing spondylitis, cervical neutral position should be maintained to avoid vertebral and spinal injuries. Although flexible fiberoptic bronchoscopic intubation is the gold standard, available FOB size is not compatible with that of the endobronchial lumen of the double lumen tube. This problem should be solved according to institut...
