AIMS Prone and supine positions for percutaneous nephrolithotomy are widely used but have their drawbacks. We report a new positioning method called "flank suspended supine position" (FSSP) for PCNL and describe our experience with PCNL in this position to evaluate its safety and efficacy. METHODS Retrospective study of 150 cases of renal stone patients treated with PCNL in a new position cal...

Urinary tract rupture is often complicated by septic shock and has a high mortality rate. Although it rarely represents a diagnostic challenge, a spontaneous rupture with urinary extravasation is a rare event which, when associated with strange and confounding clinical presentation, may rapidly evolve into life threatening septic shock. A 70-year-old patient presented with intense right leg and...

The investigation of mouse flank tumours by magnetic resonance imaging (MRI) is limited by the achievable spatial resolution, which is generally limited by the critical problem of signal-to-noise ratio. Sensitivity was improved by using an optimized solenoid RF micro-coil, built into the animal cradle. This simple design did not require extensive RF engineering expertise to construct, yet allow...

Typically flank milling is used to machine ruled surfaces. In this paper, a method of designing doubly curved NURBS surfaces for flank milling using the least squares method is given. In this method, grazing points generated by the Bedi et al. [4] tool positioning method are used as sample points. The user defines the degree and the number of control points along two parametric directions of th...

In the present work, two different types of artificial neural network (ANN) architectures viz. back propagation neural network (BPNN) and radial basis function network (RBFN) have been used in an attempt to predict flank wear in drills. Flank wear in drill depends upon speed, feed rate, drill diameter and hence these parameters along with other derived parameters such as thrust force, torque an...

Acute pancreatitis is not an uncommon disease in an emergency department (ED). It manifests as upper abdominal pain, sometimes with radiation of pain to the back and flank region. Isolated left flank pain being the sole manifestation of acute pancreatitis is very rare and not previously identified in the literature. In this report, we present a case of acute pancreatitis presenting solely with ...

Fibroblast growth factors (FGFs) act as signals in the developing limb and can maintain proliferation of limb bud mesenchyme cells. Remarkably, beads soaked in FGF-1, FGF-2, or FGF-4 and placed in the presumptive flank of chick embryos induce formation of ectopic limb buds, which can develop into complete limbs. The entire flank can produce additional limbs, but generally wings are formed anter...

This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...

A model of the flank wear of cutting tools is developed by using linear control theory. The flank wear is assumed to consist of a mechanically activated and a thermally activated component. The wear process is mathematically treated as a feedback process, whereby the progressive wear raises the cutting forces and temperature thereby increasing the thermally activated wear-rate, and contributes ...

Introduction: Flank terraces are topographically subtle, laterally extensive structures on the flanks of several large Martian volcanoes [1]. The origin of terraces has been ascribed to several mechanisms, including elastic self-loading [2], lithospheric flexure [3], gravitational spreading [4], magma chamber tumes-cence [5], and shallow slumping [6]. Here we summa-rise the results of our work ...
