Puccini et al. used Eq to express the settling distance h p (t) at time t as an equation describing the sigmoidal sedimentation curve []. (1) Here, h ∞ is the maximum settling distance after a sufficiently long time, t 50 is the time when the settling distance is half of h ∞, and β is a … WebSyllectometry is a measuring method that is commonly used to assess red blood cell (RBC) aggregability. In syllectometry, light is incident on a layer of whole blood initially exposed to shear flow. The backscattered light is measured after abruptly stopping the driving mechanism. The resultant time-dependent intensity plot is called the syllectogram. …
