Los detectores de radiación gamma que usan centelladores, siguen teniendo una gran relevancia en varios campos como es el estudio las radiaciones la física nuclear, medidas medioambiental, protección radiológica y industria. El grupo investigación INFISA adscrito a FCF UNMSM, está ubicado Instituto Investigación Física, cuenta con tres centelladores sólidos inorgánicos yoduro sodio dopado talio...

Using Japanese firm data, this paper examines the relationship between firm value and financing decision factors within a free cash flow (FCF) framework. The findings are broadly consistent with the positive tax benefits hypothesis. We find that in firms leverage is positively related to firm value and dividends are negatively related to firm value during the sample period, 1985 to 1996. The re...

Growing evidence suggests that on-pathway amyloid-β (Aβ) oligomers are primary neurotoxic species and have a direct correlation with the onset of Alzheimer's disease (AD). One promising therapeutic strategy to block AD progression is to reduce the levels of these neurotoxic Aβ species using small molecules. While several compounds have been shown to modulate Aβ aggregation, compounds with such ...

In this paper the theoretical aspects of estimating vegetation parameters from SAR interferometry are presented. In conventional applications of interferometric SAR (INSAR), the phase of the interferogram is used to retrieve the location of the scattering phase center of the target. Although the location of scattering phase center for point targets can be determined very accurately, for a distr...

The country earns substantial foreign exchange from the food and beverage sector, primary sector for people's needs. This study aims to analyze effect of debt equity ratio (DER), return on assets (ROA), free cash flow (FCF), growth (GRW). uses five companies in 2015 2019 with quarterly financial reports. results using fixed-effect model prove that all variables studied significantly affect pric...

Xerogels consisting of SiO2 and TiO2 were explored for controlled release of brilliant blue FCF (BBF). Both SiO2 and SiO2–TiO2 xerogels were prepared by way of sol–gel processing, and the BBF release behavior was compared. SiO2–TiO2 xerogels with varying TiO2 content were also studied and the BBF release behavior was determined for each SiO2–TiO2 xerogel. It was found that the release of BBF fr...

The multigrid-reduction-in-time (MGRIT) technique has proven to be successful in achieving higher run-time speedup by exploiting parallelism time. goal of this article is develop and analyze a MGRIT algorithm using FCF-relaxation with time-dependent time-grid propagators seek the finite element approximations unsteady fractional Laplacian problems. multigrid line smoother proposed Chen et al.
