As a typical buffer energy absorbing structure, thin-walled tube filled with foam aluminum has good mechanical properties and absorption characteristics. Therefore, the axial compression performance of square was experimentally studied by quasi-static loading method. On basis existing experimental research theoretical analysis, strain rate is introduced into dynamic theory, mathematical model a...

Chest tube insertion is the most commonly performed procedure in the thoracic surgery practice. This surgical procedure has various complications, however, Horner’s syndrome resulting from compression of the stellat ganglia due to apical insertion of chest tube is extremely rare. In this article a 21-year-old male patient who was treated with chest tube insertion for spontaneous pneumothorax at...

Tubular structural members with slender cross-sections are susceptible to failure through local buckling of their tube walls. Previous numerical studies steel elliptical hollow sections in compression predicted the modes and ultimate loads particularly specimens, results used calibrate design methods for sections. Although these parametric were conducted across a wide slenderness range, it was ...

The present paper deals with the experimental and computational study of axial collapse of the aluminum metallic shells having combined tube-frusta geometry between two parallel plates. Shells were having bottom two third lengths as frusta and remaining top one third lengths as tube. Shells were compressed to recognize their modes of collapse and associated energy absorption capability. An axis...

supply to cranial nerves X and XII, and thus carotid dissection after minor trauma may lead to sudden cranial nerve X and XII palsies. For this reason, in the present case, MR angiography and carotid triplex scan took place but did not reveal any abnormality. Additionally, Tapia’s syndrome can be considered as a localized lesion at the crossing of the recurrent laryngeal and hypoglossal nerves....

BACKGROUND The aim of this study was to examine the application of the Eschmann tracheal tube introducer (ETTI) with 4 types of supraglottic airway devices (SADs) using a child-manikin. METHODS A total of 79 paramedics were asked to exchange the 4 SADs for an endotracheal tube with the ETTI in 3 different scenarios using a randomized crossover study format: normal airway without chest compres...
