purpose: to report a case of unilateral aspergillus fumigatus interface keratitis after laser in situ keratomileusis (lasik). case report: a 22-year-old woman developed corneal infiltrates located at the flap- stroma interface in her left eye 48 hours after myopic lasik. the infiltration progressed despite administration of topical fortified antibiotics therefore, the flap was lifted and irriga...
A problem of reflection and transmission of a plane shear wave incident at a corrugated interface between transversely isotropic inhomogeneous and visco-elastic half-spaces is investigated. Applying appropriate boundary conditions and using Rayleigh’s method of approximation expressions for reflection and transmission coefficients are obtained for the first and second order approximation of the...
In this paper the tunable M-channel filters based on Thue-Morse heterostructures consisting of single -negative materials has been studied. The results showed that the number of resonance modes inside the zero- gap increases as the number of heterogenous interface, M, increases. The number of resonance modes inside the zero- gap is equal to that of heterogenous interface M, and it can be used a...
Abstract Explosive welding is a solid state process in which bond is produced by a high oblique impact of two plates with the controlled explosive charge. In this paper, the explosive welding of Ms90 brass flyer plate with the St14 steel base plate are considered by using the parallel set up geometry. From the practical viewpoint, various parameters such the stand-off distance, dynamic angl...
a study of the features of the international children's digital library's user interface from the viewpoint of users and presenting a proposed model zohreh hassanpoor* saeed rezaei sharifabadi** alzahra university of tehran this research studies iranian children's understanding of the meaning of conceptual signs and icons existing in the user interface of the internati...
In the present research, the effect of standoff distance on corrosion properties of the joint of three aluminum–steel explosive layers has been studied. For this purpose, the samples were welded with various standoff distance under constant explosive load. Optical Microscopy and Scanning Electron Microscopy were used to measure the quality of the joint and type of interface. Furthermore, point ...
Introduction: User interfaces are a crucial factor in ensuring the success of mobile applications. Mobile Educational Applications not only provide flexibility in learning, but also allow learners to learn at any time and any place. The purpose of this article is to investigate the effective factors affecting the design of the user interface in mobile educational applications. Methods: Quantita...
In this paper, the density of states (DOS) of a planar d-wave Josephson junction is studied analytically. Two high temperature superconductors are separated by an interface with finite transparency coefficient. The c-axes are parallel to the interface and ab-axes have a mis-orientation. The tunneling occurs via the interface because of phase difference between superconducting bulks. The effec...
In this research, Effect of explosive ratio parameter on interface properties of explosively bonded copper-410 martensitic stainless steel were investigated, plates were welded in constant standoff distance with different explosive ratios. Optical microscopy, scanning electron microscopy, Microhardness and Tensile shear tests were carried out. The results showed that wavelength, wave amplitude,...
Nowadays total joint replacements are widely used in the world, so in average 800,000 joint surgeries are done yearly only in Europe and North America. However implant loosening is and remains as the major issue of all implant failures and therefore causes revision surgery procedures. Studies and experiments have identified poor fixation of implants most likely is the main cause of long term im...
