Optical Measurements of Nonlinearity in the Middle Ear

Dispersion and Nonlinearity in Ultra-Optical Ga2O3 and TiO2-Bi2O3-PbO Glass Systems

Dispersion, as the characteristic variation of refractive index with wavelength, is more pronounced, where the wavelength is approaching to the absorption band. In ultra-optical glasses, the nonlinear refractive index, concerning to the light intensity dependent phenomenon, becomes considerable. Here, two ultra-optical property glass systems; TiO2-Bi2O3-PbO (TBP...

Study of seasonal distribution of dust in the Middle East region using CALIOP and MODIS data

Aerosol optical depth in 550 nm and angstrom exponent measurements with MODIS have been studied with 1-degree resolution for the period 2006-2017 in the middle east. Moreover, tropospheric aerosol optical depth and depolarization ratios measured at 532 nm with CALIOP have been studied for same area and same period of time too. These parameters have been classified seasonally. Optical depth resu...

“Study of stable gallium oxide heavey metal Ga2O3-Bi2O3-PbO system glasses proposed as a base for optically noble glazes and enamels”

Ultra optical glasses are proposed for attaining noble glazes of high reflection and shine. In addition, these glasses can be used as semi-mirrors and optical instruments. In this reseach attempts were devoted mainly to introduce a glass system with the highest possible refractive index in which the highest reflection is desirable. Thus different amounts of heavy metal oxides modifiers, such as...

Non-invasive Assessment of Bacterial Biofilm in the Middle Ear Using Low-coherence Interferometry/optical Coherence Tomography and Acoustic Measurements by Cac Thi Nguyen Dissertation

Effect of Suctioning of the Middle Ear Effusion on Hearing Condition Before Ventilation Tube Insertion

Abstract OME is a Common disease in children. over than 90% of children in preschool ages experienced this disease once at least. Despite medical therapy about 10% of the OME patients won't improved and these are the group of patients who referred to as chronic OME patients. Insertion of VT in TM is an accepted therapy for these patients and during surgery for insertion of VT, suctioning of mi...
