Cyanine fluorophores exhibit greatly improved photostability when covalently linked to stabilizers, such as cyclooctatetraene (COT), nitrobenzyl alcohol (NBA) or Trolox. However, the mechanism by which photostabilization is mediated has yet to be determined. Here we present spectroscopic evidence that COT, when covalently linked to Cy5, substantially reduces the lifetime of the Cy5 triplet stat...

Stochastic distribution methods were used to construct patient flow simulation sub-models such as inflow, length of stay (LoS), cost treatment (CoT) and clinical pathways (CPs). However, the inflow rate demonstrates seasonality, trend, variation due natural human-made factors. LoS, CoT CPs are determined by social-demographics factors, laboratory test results, resource availability healthcare s...

O objetivo do estudo foi estimar, por meio de sensoriamento remoto (OLI/LANDSATA 8 – LS8), as concentrações clorofila-a (Cl-a) e carbono orgânico total (COT). Entre 2017 2018 foram realizadas seis coletas amostras água nos reservatórios Umari Mendubim, no semiárido nordestino, para determinação dos valores Cl-a COT. Foram calculados os coeficientes correlação entre bandas espectrais das imagens...
