Results of research absorbed dose rate dependence on distance and positioning accuracy standard dosimetric beta-radiation sources at the new AT200 calibration facility (by ATOMTEX SPE) are presented. The non-uniform profile fields created by with strontium-90 + yttrium-90, krypton-85 promethium-147 radionuclides under conditions as specified in ISO/DIS 6980-2:2021(E) international was investiga...

An algorithm based on the physics of radiative transfer in vegetation canopies for the retrieval of vegetation green leaf area index (LAI) and fraction of absorbed photosynthetically active radiation (FPAR) from surface reflectances was developed and implemented for operational processing prior to the launch of the moderate resolution imaging spectroradiometer (MODIS) aboard the TERRA platform ...

This paper reviews the several methods available for estimating the fAPAR, both at local and large scale. The fAPAR definition is first discussed with regards to the directionality of the incident radiation. Then, the several techniques to estimate fAPAR from local ground measurements are reviewed with emphasis on the sampling strategy. We then describe methodologies to upscale fAPAR measuremen...

The purpose of this study is to predict human jejunal permeability (P(eff)) and fraction absorbed in human (%F(a)) for a group of antibacterial fluoroquinolones (FQs), by using a biophysical model based on measured Caco-2 permeability. The predicted P(eff) (in 10(-4) cm · s(-1) units) ranged from 0.7 (norfloxacin) to 4.5 (pefloxacin). The calculated %F(a) for norfloxacin = 51% (lit. 35%) and fo...

[1] The fraction of absorbed photosynthetically active radiation, fAPAR, is an important biophysical characteristic in models of gas exchange between the terrestrial boundary layer and the atmosphere, as well as in the analysis of vegetation productivity. Synoptic estimation of fAPAR has been performed by using NDVI as a linear proxy of fAPAR, despite the saturation of NDVI at fAPAR beyond 0.7....

alzheimer’s disease (ad) is a neurodegenerative disease that was characterized with deposit of beta amyloid (aβ) aggregate in senile plaque. oxidative damage to neurons and loss of cholinergic neurons in forebrain region are observed in this disease. melissa officinalis is a medicinal plant from lamiaceae family, used traditionally in the treatment of cognitive disorders. it has cholinomimetic ...

The use of a serologically active fraction of serum in parallel with whole serum, in testing for the sheep cell agglutinating factor in rheumatoid arthritis, was suggested by Svartz and Schlossmann (1953) and by Ziff, Brown, Badin, and McEwen (1954). Claims of higher sensitivity and specificity have been re-emphasized in more recent publications (Ziff, Brown, Lospalluto, Badin, and McEwen, 1956...
