چکیده
Ingestion of foreign bodies is one of the common causes of emergency department visits. History, physical examination, and noninvasive imaging such as plain radiography and computer tomography scan can guide us regarding the type and location of the ingested foreign body. Most of the patients can be managed conservatively but few may need endoscopic evaluation and treatment.

Mistilings with dominoes
We consider placing dominoes on a checker board such that each domino covers exactly some number of squares. Given a board and a type of domino, we define the mistiling ratio as the minimum proportion of squares that are covered in a maximal packing of the board with dominoes of that type. In this note we determine and bound the mistiling ratio for some types of dominoes on the infinite checker...
متن کاملDistribution and relative frequency of immunohistochemically detected endocrine cells in the stomach of New Zealand White rabbit (Oryctolagus cuniculus)
Background: Gastrointestinal (GI) endocrine cells produce many GI hormones that perform various physiological functions of the digestive system. Aims: We aimed to investigate the presence and distribution of immunoreactive (IR) endocrine cells to glucagon, somatostatin, cholecystokinin-8 (CCK-8), serotonin, secretin and histamine in the stomach of adult male Ne...
متن کاملProviding an algorithm for solving general optimization problems based on Domino theory
Optimization is a very important process in engineering. Engineers can create better production only if they make use of optimization tools in reduction of its costs including consumption time. Many of the engineering real-word problems are of course non-solvable mathematically (by mathematical programming solvers). Therefore, meta-heuristic optimization algorithms are needed to solve these pro...
متن کاملDigestive system anatomy of the Acipenser persicus: New features
Sturgeon is one of the most important species of the Caspian Sea aquatics. Unfortunately, this species faces the threat of extinction today. This makes specific studies on any type of sturgeons more important than before. Studies like histological studies, radiology, and sonography, all require a complete understanding of the anatomy of this fish. Since pilot studies showed some misconceptions ...
