Unusual case of intestinal obstruction

open access: yesJournal of Dr. NTR University of Health Sciences, 2018
Internal hernia is a rare cause of small bowel loop obstruction. Hernia through a defect of the broad ligament is extremely rare. We report a case of small bowel obstruction resulting from the herniation of small bowel through a unilateral defect in the ...

Effects of stray AC on delamination of epoxy coatings with defects in 3.5% NaCl solution

open access: yesInternational Journal of Electrochemical Science, 2017
The stray current induced coating delamination at defect areas is complicated and with its mechanism uncovered. In this study, the delamination mechanism of epoxy coating at defect areas under stray alternating current (AC) interference was investigated ...

Small ventricular septal defects in adults [PDF]

open access: yesEuropean Heart Journal, 1998
To establish the frequency of complications in adults with small ventricular septal defects, which have not undergone surgery.One hundred and eighty-eight adults aged 17-72 (mean, 29.2) years with a small ventricular septal defect were studied. They were referred to a national cardiac centre (National Heart Hospital) and specialized grown-up congenital

Defective Choosability of Graphs without Small Minors [PDF]

open access: yesThe 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 ...

Filling Defects in Small Bowel Urinary Conduits [PDF]

open access: yesJournal 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,

Extended Langford Sequences with Small Defects

open access: yesJournal 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

A Light-Weight Network for Small Insulator and Defect Detection Using UAV Imaging Based on Improved YOLOv5

open access: yesSensors, 2023
Insulator defect detection is of great significance to compromise the stability of the power transmission line. The state-of-the-art object detection network, YOLOv5, has been widely used in insulator and defect detection. However, the YOLOv5 network has
