Filling Defects in Small Bowel Urinary Conduits [PDF]
Journal of Urology, 1981 Radiographic evaluation of patients with urinary diversion by small bowel conduit includes excretory urography, loopography, and, if necessary, percutaneous pyelography. Five patients with discrete filling defects in their conduits are discussed. These defects represented stones (two cases), antirefluxing ureteral nipples, metastatic bladder carcinoma,

A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]
, 2014 An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...

Extended Langford Sequences with Small Defects
Journal of Combinatorial Theory, Series A, 1998 A \(k\)-extended Langford sequence of defect \(d\) and length \(m\) is a sequence \(s_1,\dots,s_{2m+1}\) in which \(s_k=\varepsilon\), where \(\varepsilon\) is the null symbol and each other member of the sequence comes from the set \(S=\{d,d+1,\dots,d+m-1\}\). Each \(j\in S\) occurs exactly twice in the sequence and the two occurences are separated by

Defective Choosability of Graphs without Small Minors [PDF]
The Electronic Journal of Combinatorics, 2009 For each proper subgraph $H$ of $K_5$, we determine all pairs $(k,d)$ such that every $H$-minor-free graph is $(k,d)^*$-choosable or $(k,d)^-$-choosable. The main structural lemma is that the only 3-connected $(K_5-e)$-minor-free graphs are wheels, the triangular prism, and $K_{3,3}$; this is used to prove that every $(K_5-e)$-minor-free graph is 4 ...

Regeneration of the Gastrointestinal Tract After Using a Small Intestine Submucosa Patch—A Rat Model
BiomedicinesBackground: Necrotizing enterocolitis (NEC) is a life-threatening condition characterized by necrosis of the gastrointestinal tract caused by hypoperfusion and hypoxia-induced inflammation. Surgical treatment often requires resection, with high morbidity

Highly-Sensitive and Frequency-Selective Imaging of Defects via Local Defect Resonance [PDF]
, 2014 In this paper, a consistent way to enhance acoustic, optical and thermal defect responses is suggested by using selective ultrasonic activation of defects based on the concept of local defect resonance (LDR).

Tagged repair techniques for defect tolerance in hybrid nano/CMOS architecture [PDF]
, 2010 We propose two new repair techniques for hybrid nano/CMOS computing architecture with lookup table based Boolean logic. Our proposed techniques use tagging mechanism to provide high level of defect tolerance and we present theoretical equations to ...
