background adaptation is an important process for humans. children, who are physically or mentally disabled, impose special stresses on their families, parents and in particular on their mothers. objectives this study examines the relationship between the characteristics of mothers who have educable mentally retarded children, and their adaptation based on roy’s adaptation model. patients and m...

Abstract The coupling between a moving ground-state atom and the quantum electromagnetic field is at origin of several intriguing phenomena ranging from dynamical Casimir emission photons to Sagnac-like geometric phase shifts in interferometers. Recent progress this emerging reveals unprecedented connections non-trivial aspects modern physics such as electrodynamic retardation, non-unitary evol...

A Swept Source Polarization-Sensitive Optical Coherence Tomography (SS-PS-OCT) instrument has been designed, constructed, and verified to provide high sensitivity depth-resolved birefringence and phase retardation measurements of the retinal nerve fiber layer. The swept-source laser had a center wavelength of 1059 nm, a full-width-half-max spectral bandwidth of 58 nm and an A-line scan rate of ...

A novel polarization-sensitive optical coherence tomography (PS-OCT) system was developed using polarization maintaining (PM) optical fibers and fiber coupler to measure birefringence properties of samples. Polarization distortion due to PM fibers and coupler can be calibrated with different polarization states during two consecutive A-scans. By processing the analytical interference fringe sig...

For conventional superconductors the electron-electron interaction is strongly reduced by retardation effects, making the formation of Cooper pairs possible. In the alkali-doped Fullerides, however, there are no strong retardation effects. But dielectric screening can reduce the electron-electron interaction sufficiently, if we assume that the random-phase approximation (RPA) is valid. It is no...
