According to the direct homogenization theory of inhomogeneous material, a single medium homogenization constitutive model of the confined concrete in the steel box-concrete combined member has been established, and model parameters have been determined by the measured data of the bending test. By analyzing the theoretical ultimate strength and overall process curve, the results obtained is con...

OBJECTIVE To determine if the 8 cm upper limit for mediastinal width applies in the trauma setting of today. To define the upper limit of normal mediastinal width for supine chest films. METHODS A retrospective review of chest computed tomography scans was conducted to determine the width and position of the mediastinum within the supine chest. Radiographs were performed using a model that en...

Abstract Introduction Obstructive sleep apnea (OSA) is well known to often improve with non-supine positioning as opposed supine positioning. The prevalence of OSA that may on proper 50-60% and the appears when disappears 25-30%. Sleeping in a lateral thought reduce pressure airway, shift directional effect gravity airway structures, counteract physiologic genioglossus collapse occurs supine. O...

In this work, silver nanowire inks with hydroxypropyl methylcellulose (HPMC) binders were coated on polyethylene terephthalate (PET) substrates and welded via flash white light and ultraviolet C (UV-C) irradiation to produce highly conductive transparent electrodes. The coated silver nanowire films were firmly welded and embedded into PET substrate successfully at room temperature and under amb...

Submitted for the MAR13 Meeting of The American Physical Society The Onset of Plasticity in thin Polymer Films BEKELE J. GURMESSA, ANDREW B. CROLL, North Dakota State University — Polymers are widely used materials because of their numerous advantageous mechanical properties, for example their high degree of toughness. Despite the fundamental importance of the onset of plastic deformation to ma...

STUDY DESIGN Retrospective, cross-sectional. OBJECTIVE To determine the initial curve correction of the providence brace (PB) and to determine to what extend the in-brace Cobb angle corresponds to the curve seen on supine lateral bending radiographs (SLBR). SUMMARY OF BACKGROUND DATA SLBR are used to assess curve flexibility in patients undergoing surgical treatment for adolescent idiopathi...

background nowadays percutaneous nephrolithotomy (pcnl) is performed in prone and supine positions. physiologic solutions should be used to irrigate during pcnl. irrigation can cause hemodynamic, electrolyte and acid-base changes during pcnl. objectives the current study aimed to compare the electrolyte, hemodynamic and metabolic changes of prone and complete supine pcnl. patients and methods i...

Polymer microelectromechanical system MEMS devices are promising for biological applications such as development of biosensors and biomechanical devices. In order to develop polymer biological MEMS BioMEMS , polymer microfabrication techniques are required, and the nanomechanics studies, including measurement of the nanomechanical properties of the polymer materials, must be carried out. This a...
