In a graph G = (V,E), a subset $S⊂V$ is said to be an open packing set if no two vertices of S have a common neighbour in G. The maximum cardinality of an open packing set is called the open packing number and is denoted by $ρ^{o}$. This paper further studies on this parameter by obtaining some new bounds.

In this paper, the effects of two different Particle Size Distributions (PSD) on packingbehavior of ideal rigid spherical nanoparticles using a novel packing model based on parallelalgorithms have been reported. A mersenne twister algorithm was used to generate pseudorandomnumbers for the particles initial coordinates. Also, for this purpose a nanosized tetragonal confinedcontainer with a squar...

OBJECTIVE To assess the value of magnetic resonance cholangiography with gadobenate dimeglumine (Gd-BOPTA) where there is a suspicion of bile leakage in the post-liver transplant patient. PATIENTS AND METHODS Eight patients who had undergone a liver transplant underwent 14 MR cholangiograms, five of whom presented bile leakage while the other three had no biliary system complications. The res...

A 45-year-old man was admitted for pain in the upper right abdominal quadrant that had been evolving for months. His previous medical history was unremarkable. The physical examination showed a painful and tense abdomen in the right hypochondrium but the rest was pain free. Biological analysis showed an inflammatory syndrome (C-reactive protein 29.54mg/L). Liver enzymology and urine and blood c...

An 18-year-old womanwith superficial spreadingmelanoma in the epigastric region arising from a congenital nevus (Clark level III, Breslow thickness 3.56mm, mitotic rate 2mitoses/mm2), previously removed, was referred for a sentinel lymph node biopsy. After intradermal injection of 111MBq of 99mTc-nanocolloid (Nanocoll) around the excisional biopsy scar, lymphatic mapping was initiated. Dynamic ...

In textile industry, marker planning is one of the main operations in the cutting fabric stage. Marker packing is usually used to maximize cloth exploitation and minimize its waste. In this research, a method is used based on new found meta-heuristic imperialist competitive algorithm (ICA) and Bottom-Left-Fill Algorithm (BLF) to achieve optimal marker packing. Function of the proposed method wa...

BACKGROUND Fitz-Hugh-Curtis syndrome (FHCS) is caused by inflammation of perihepatic capsules associated with pelvic inflammatory disease. In recent years, infections with nontuberculous mycobacteria (NTM) have been increasingly occurring in immunocompromised and immunocompetent patients. However, NTM has never been reported in patients with FHCS. We present the first case of a patient with ext...

UNLABELLED OBJECTIVES The authors present a novel approach to nonresectional therapy in major hepatic trauma utilizing intraabdominal perihepatic vacuum assisted closure (VAC) therapy in the porcine model of Grade V liver injury. METHODS A Grade V injury was created in the right lobe of the liver in a healthy pig. A Pringle maneuver was applied (4.5 minutes total clamp time) and a vacuum a...
