We study complex dynamics of a cutting process, a recently developed frictional model of cutting process in [Rusinek et al., 2014] to gain better insight into the mechanics of frictional chatter and the factors affecting it. The new model takes into account the forces acting on the tool face as well as on the tool flank. We first present nonlinear dynamic behavior using bifurcation diagrams for...

PURPOSE The aim of this study was to investigate the changing pattern in the use of intravenous pyelogram (IVP), conventional computed tomography (CT), and non-contrast-enhanced computed tomography (NECT) for evaluation of patients with acute flank pain. MATERIALS AND METHODS We retrospectively reviewed the medical records of 2,180 patients with acute flank pain who had visited Bundang Jesaen...

In tetrapods, limbs develop at two specific positions along the anteroposterior axis of the embryo, whereas other regions of the embryo, most prominently the neck and the flank, are limbless. However, the flank can generate an ectopic limb when the Fgf-feedback loop crucial for the initiation of limb budding is activated. Thus, despite its limblessness, the flank is a limb-competent area. Using...

The analysis of drill cutting angles is important for the design of high-performance drill geometry. The cutting angles along the cutting edge of a drill are determined by the combination of its flute and flank surfaces. This paper examines the analysis of both flute and flank surface models and the evaluation of drill cutting angles. A new mathematical model for an arbitrary drill flute face i...

A 47-year-old woman was referred to our hospital for the management of her large abdominal mass. She had a history of right flank pain off and on for 2-3 years. She was admitted to the provincial hospital in the previous four days due to right flank pain and nausea. She had no history of trauma. Abdominal computed tomography (CT) was performed and liposarcoma was suspected in the right flank. S...

Flank transparency is the perception of a colored transparent filter evoked by apparent-motion displays containing as few as two colors. Displays of flank transparency contain a random array of line segments placed on a uniform background. Small flanks are added to the line segments if the segments fall in the interior of a moving virtual shape, such as a virtual disk. This leads to the percept...

background: this study was designed to investigate the efficacy of pentoxifylline (ptx) in the treatment of irradiated wounds. materials and methods: ten female pigs of the large white strain were used in these investigations. six skin fields, 4 * 4 cm and separated from each other by 4 cm, were marked out on each flank and those on left flank were irradiated with 18gy single dose of 250 kv x-r...

Originally described in 1853 by Dr. Morel-Lavellee, closed internal degloving injuries represent an important, althoughuncommon, source of morbidity in trauma patients. These injuries are typically the result of a shearing or crushing force thattraumatically separates the skin and subcutaneous tissue from the underlying fat. This results in disruption of perforatingblood vessels and lymphatics,...
