Based on a vector wave theory of volume holograms, dependence of holographic reconstruction on the polarization states of the writing and reading beams is discussed. It is found that under paraxial approximation the circular polarization holograms provide a better distinction of the reading beams. Characteristics of recording polarization holograms in thick phenanthrenequinone-doped poly(methyl...

Evidence has been presented (1) indicating the occurrence of critical zones in the precipitation of the proteins of blood, Cpon the addition of increasing amounts of sodium sulfate at these zones there is not a marked increase in the quantity of protein precipitated for a given increase in salt concentration. The eones occur in the neighborhood of the following concentrations of sodium sulfate ...

The single-tooth restoration has become one of the most widely used procedures in implant dentistry. Improvements to the abutment implant interface design, wider implant platforms and the increased use of cemented restorations have greatly enhanced this procedure. Nonetheless, limitations in the volume of underlying bone and heavy occlusal loads, with or without parafunctional habits, still con...

Microwave imaging for breast cancer detection has been of significant interest for the last two decades. Recent studies focus on solving the imaging problem using an inverse scattering approach. Efforts have mainly been focused on the development of the inverse scattering algorithms, experimental setup, antenna design and clinical trials. However, the success of microwave breast imaging also he...

Polarization gating is a popular technique in biomedical optics. It is widely used to inspect the surface of the tissues (under colinear or cocircular detection) or instead to probe the volume (cross-linear detection), without information on the probed depth. Elliptical polarization is introduced to explore the possibility of probing diffuse tissues at selective depths. A thorough Monte Carlo s...

The binding to human albumin of fluorescein monoglucuronide, a fluorescent metabolite of fluorescein, was studied using two methods: pressure dialysis and fluorescence polarization. Both methods indicated that fluorescein monoglucuronide binds to human albumin more loosely than fluorescein. The free fraction in human plasma estimated from the dissociation constant and the number of binding site...

Purpose: A deficit was identified in the traditional method of making homeopathic dilutions by 1:9 or 1:99 serial based on physical units mass volume. When chemical unit mole is considered, mass-based dilution nitroglycerin ethyl alcohol has a 1:48.8 molar ratio. In order to provide ratio, ratios required for formulations with lithium carbonate: lactose (diluent) and lead phosphate: are 1:41.7 ...

Here, we examined multitemporal behavior of fully polarimetric SAR (PolSAR) parameters at L-band in relation to the stem volume of boreal forests. The PolSAR parameters were evaluated in terms of their temporal consistency, inter-dependence and suitability for forest stem volume estimation across several seasonal conditions (frozen, thaw and unfrozen). The satellite SAR data were represented by...
