Introduction: Esophageal foreign bodies are important and serious cause of morbidity and mortality in both children and adults, usually as a result of serious complications, such as perforation, necrosis, mediastinitis, and fistulation. Therefore, rapid and accurate diagnosis with subsequent removal is very important. Clinical Case: We present and discuss the presentation, diagnosis and surgical management of a 6-year-old with a 2-year history of ingested coin locked in the oesophagus. Discussion: Diagnosis was established by upper gastrointestinal endoscopy, barium swallow and chest x-ray. The coin was removed by open surgery via oesophagotomy through right thoracotomy after failed retrieval via rigid oesophagoscopy. Conclusion: Surgical treatment in the form of esophagotomy via thoracotomy may be necessary in some cases of impacted foreign bodies in the esophagus where endoscopic removal is unsuccessful.

Mixed-model U-shaped assembly line balancing problems (MMUALBP) is known to be NP-hard resulting in it being nearly impossible to obtain an optimal solution for practical problems with deterministic algorithms. This paper pre-sents a new evolutionary method called combinatorial optimisation with coincidence algorithm (coin) being applied to Type I problems of MMUALBP in a just-in-time production system. Three objectives are simultaneously considered;minimum number workstations, minimum work relatedness, and minimum workload smoothness. The variances of coin are also proposed, i.e. CNSGA II, and coin-MA. coin and its variances are tested against a well-known algo-rithm namely non-dominated sorting genetic algorithm II (NSGA II) and MNSGA II (a memetic version of NSGA II). Experimental results showed that coin outperformed NSGA II. In addition, although coin-MA uses a marginal CPU time than CNSGA II, its other performances are dominated.

A symmetric all-organic non-aqueous redox flow-type battery was investigated employing the neutral small molecule radical 3-phenyl-1,5-di-p-tolylverdazyl,which can be reversibly oxidized and reduced in one-electron processes,as the sole charge storage *** voltammetry of the verdazyl radical in 0.5 M tetrabutylammonium hexa fluoro phosphate(TBAPF6)in acetonitrile revealed redox couples at-0.17 V and-1.15 V ***+/Ag,leading to a theoretical cell voltage of 0.98 *** the dependence of peak currents on the square root of the scan rate,diffusion coefficients on the order of 4 x 10 6 cm2 s-1 were *** performance was assessed in a static cell employing a Tokoyuma AHA anion exchange membrane,with 0.04 M verdazyl as catholyte and anolyte in 0.5 M TBAPF6 in acetonitrile at a current density of 0.12 mA *** coulombic efficiencies were good(94%-97%)throughout the experiment,the capacity faded gradually from high initial values of 93%of the theoretical discharge capacity to 35%by the 50th *** and energy efficiencies were 68%and 65%,*** analysis by cyclic voltammetry revealed that decomposition of the active material with cycling is a leading cause of cell degradation.

Background: Foreign body (FB) ingestion by children is a common problem worldwide. Management may include endoscopic removal. This paper describes the clinical findings, sites and types of FBs, and outcomes in children who underwent endoscopic management of ingested FBs at our institution. The published literature regarding the management of FB ingestion in children is also reviewed. Methods: We retrospectively reviewed the records of all patients aged coins being the most common. Endoscopic removal was successful in 43 patients. The 17 patients with tracheobronchial foreign bodies included 9 males and 8 females with a mean age of 3.2 years. The most common symptoms were breathing difficulty in 12 patients (71%) and coughing in 3 (18%). The most common tracheobronchial FBs were nuts (10 patients). Bronchoscopic removal was successful in all 17 patients. Conclusions: coins were the most common gastrointestinal FBs, and nuts were the most common tracheobronchial FBs. Clinical presentations were variable, and a high index of suspicion is necessary. Endoscopic removal is safe and effective, and early diagnosis and management result in favorable outcomes.

Current minimization programs do not permit full control over different aspects of minimization algorithm such as distance or probability measures and may not allow for unequal allocation ratios. This article describes the implementation of “MinimPy” an open-source minimization program in Python programming language, which provides full customizetion of minimization features. MinimPy supports naive and biased coin minimization together with various new and classic distance measures. Data syncing is provided to facilitate minimization of multicenter trial over the network. MinimPy can easily be modified to fit special needs of clinical trials and in particular change it to a pure web application, though it currently supports network syncing of data in multi-center trials using network repositories.

Foreign body ingestion is a common emergency situation in children with one or a few objects having been ingested. Here we report our experience using endo-scopic retrieval in a female centenarian with dyspnea and foreign bodies in the esophagus. She attempted suicide by swallowing 26 coins and two other foreign bodies. A gastroscope was used to remove all foreign bodies in the lower esophagus. In total, 26 coins, one ferrous ring and one cylindrical plastic object were retrieved. To our knowledge, this is the first clinical report on retrieval of so many foreign bodies in a single case.
