The application of reciprocity principles in optics has a long history that goes back to Stokes, Lorentz, Helmholtz and others. Moreover, optical applications need to be seen in the context of applications of reciprocity in particle scattering, acoustics, seismology and the solution of inverse problems, generally. In some of these other fields vector wave propagation is, as it is in optics, of ...

Currently, sensors invade into our everyday life to bring higher life standards, excellent medical diagnostic and efficient security. Plasmonic biosensors demonstrate an outstanding performance ranking themselves among best candidates for different applications. However, their sensitivity is still limited that prevents further expansion. Here we present a novel concept of magnetoplasmonic senso...

background: despite several reports regarding the use of the occlutech figulla® flex septal occluder (offso) in adults, there are few reports on its use in children. we sought to study the result of the transcatheter closure of atrial septal defect (asd) using the offso in children ≤ 12 years. methods: w e enrolled 45 consecutive patients, ranging from 2.5 to 12 years of age, in two large pedia...

introduction in radiography, dose and image quality are dependent on radiographic parameters. the problem is caused from incorrect use of radiography equipment and from the radiation exposure to patients much more than required. therefore, the aim of this study was to implement a quality-control program to detect changes in exposure parameters, which may affect diagnosis or patient radiation do...

according to the vital role of pharmaceutical industry in health care system, pharmaceutical supply chain security, standard production and distribution of the pharmaceutical products are of great importance for pharmaceutical companies. therefore, applying technology, especially radio frequency identification (rfid), is essential to achieve these goals. moreover, due to the importance of secur...

using of colloids and polymeric microparticles are gradually increasing. it is observed that thepositive effects of particles stems in both traditional applications such as column pickings,coatings and paints to more recent technologies in diagnostics, drug delivery and optical devicesare well documented. this review focuses on importance of colloids and covers theirapplications on three level:...

introduction: in this study, arrangement of a low-cost optical tomography device compared to other methods such as frequency domain diffuse tomography or time domain diffuse tomography is reported. this low-cost diffuse optical imaging technique is based on the detection of light after propagation in tissue. these detected signals are applied to predict the location of in-homogeneities inside p...

in the past, medical device design always was performed with medical engineers, technicians and physicians in all design stages and the industrial design role was pale in this field. today the industrial design responsibilities in designing of these devices are considered increasingly. the industrial design role in medical device design was investigated in two fields. first are aesthetic and it...
