forming limit curve (flc) is an important tool for evaluation of formability of sheet metals subjected to different loading. free bulge of aluminume tubes has been investigated numerically to obtain flc. to verify the numerical results one experimental setup has been manufactured which has the ability of controlling the internal pressure and axial feed. in this study, time and zone of bursting ...
The creation of drag-reducing surfaces in deformed tubes is vital importance to thermal management, energy, and environmental applications. However, it remains a great challenge tailor the surface structure wettability inside slim complicated feature. Here, we describe an electrochemical anodization strategy achieve uniform superhydrophobic coating TiO2 nanotube arrays throughout inner deformed...
In free bending process, the axis shape of bent tube is determined by motion trajectory die. The tubes with different radii and directions can be formed continuously adjusting position posture To accurately form pre-designed tube, formation mechanism arc in process was analyzed. mathematical model between radius deviation established moving direction die also according to plane space azimuth wh...
INTRODUCTION We studied the effect of head rotation on the relative position of the right common carotid artery (CCA) and the right internal jugular vein (IJV) in patients with laryngeal mask airway (LMA) insertion to evaluate the accuracy of anatomical landmarks for right IJV cannulation. METHODS We simulated needle insertion to the right IJV on sonograms via the central landmark approach an...
We have measured total vocal-tract (VT) length, lip-tube length and glottal height during vowels on X-ray film data of short French utterances [1]. VT midpoints are determined by progressively fitting circles along the VT-length from the glottis to lip opening. The VT-length is obtained by summing up the distance between adjacent midpoints. Lip-tube length is defined as the distance between the...
A 40-YR-OLD man presented for excision of recurrent pituitary adenoma. Medical history included pulmonary tuberculosis. On chest auscultation, diminished air entry in the left axillary and supra-/infraclavicular areas were observed. Chest radiogram demonstrated evidence of collapse and/or fibrosis of most of the left lung and significant ipsilateral tracheal and mediastinal shift (fig. A). Afte...
BACKGROUND/AIM In a computed tomography (CT) examination, scanogram images are used to determine the range of the area to be imaged before scanning. The importance of scanogram image exposure has increased since total examination radiation has decreased due to technological advancements. The purpose of this study was to determine and compare radiation doses delivered to patients while the tube ...
tions and advantages of this method have been reported (Barber, J. MIilk & Food Technol., 12, 257-266, 1949), and it is well to point out here the obvious economy in incubator space, agar medium, time, and productivity. Usually, 4 to 5 ml of agar are used per tube. Samples (1 ml or some fraction thereof) aire added to the sterile, melted, and tempered agar; the tubes are agitated gently, slante...
Due to their compliance and high dexterity, biologically-inspired continuum robots have attracted much interest for applications such as medical surgery, urban search and rescue, de-mining etc. In this paper, we will present an application to medical surgery-colonoscopy by designing a pneumatic-driven flexible robotic manipulator, called ColoBot. The focus of this paper lies in the sensor-based...
BACKGROUND We explored whether positioning patients in a 25° back-up sniffing position improved glottic views and ease of intubation. METHODS In the first part of the study, patients were intubated in the standard supine sniffing position. In the second part, the back of the operating table was raised 25° from the horizontal by flexion of the torso at the hips while maintaining the sniffing p...
