In this paper, the properties of the defect mode in the photonic band gap ofone-dimensional ternary photonic crystals containing high temperature superconductorlayer (SPCs) have been theoretically investigated. We considered the quasi-periodiclayered structures by choosing two order of ternary Thue-Morse structures with mirrorsymmetry. We investigated the transmission spectra of these structure...

The field of optimization and machine learning are increasingly interplayed and optimization in different problems leads to the use of machine learning approaches‎. ‎Machine learning algorithms work in reasonable computational time for specific classes of problems and have important role in extracting knowledge from large amount of data‎. ‎In this paper‎, ‎a methodology has been employed to opt...

the aim of this investigation was to evaluate the use of polypropylene mesh and glycerol preserved bovine pericardium (gbp) to repaire abdominal wall defects in 24 clinically healthy mongrel dogs using inlay and underlay techniques. twenty four healthy mongrel dogs were used in this study. the animals were divided into two main groups according to the type of the prosthetic material used. each ...

introduction pulmonary vein stenosis includes narrowing of one or more pulmonary veins that may have congenital or acquired causes. congenital pulmonary vein stenosis is a rare condition and also a rare cause for pulmonary hypertension. since identifying the etiology of pulmonary hypertension plays a crucial role in medical and surgical planning, we decided to introduce a rare case of pulmonary...

statement of problem: digital measurement of rvg may improve diagnostic interpretation of radiographs in terms of accuracy, although it has been shown that validity of linear measurements of interproximal bone loss could not be improved by basic digital manipulations. purpose: the aim of this study was to evaluate the accuracy of radiovisiography (rvg) in the linear measurement of interproximal...

background: brain type natriuretic peptide (bnp) is a cardiac hormone that is secreted mainly by the ventricles in response to volume expansion and pressure load. it can predict post-operative complications after heart surgery in adults. we sought to investigate the prognostic value of bnp in children after heart surgery. methods: we measured the bnp serum levels in 96 children with congenital ...

today, congenital heart diseases may be treated without surgery through advances in interventional cardiology. however, complications such as infection and thrombus formation may develop due to foreign materials used during these procedures. surgical intervention may be required for the removal of the device utilized for the procedure. in this case report, we present the surgical treatment of a...

Roll forming process is used for manufacturing sheet metal parts by successive bending and creating the final shape with gradual deformation. In this article, deformation of a pre-punched sheet due to the roll forming process was studied. Two main defects in the roll forming process are ovality of holes and bow defect. The ovality of the hole is influenced by the process parameters including sh...
