Such methods track progressive degenerative changes from the late teens, until the observations reach their peak breakdown and plateau, most commonly between 50 and 60 years (İşcan et al., 1984a, b, 1985; Lovejoy et al., 1985; Brooks and Suchey, 1990; Buckberry and Chamberlain, 2002).
Pasting parameters such as peak viscosity, breakdown, final viscosity, peak viscosity/final viscosity, and peak viscosity-final viscosity exhibited significant correlations with LPD (p < 0.05) regardless of starch source.
Compared to O. rufipogon, Hwaseong showed higher peak viscosity, breakdown viscosity, cool paste viscosity, and consistency of starch, whereas Hwaseong was found to be lower in pasting temperature and setback viscosity.
The clinical course of mucositis is well characterized in this hamster cheek-pouch model of radiation-induced mucositis [ 12], with peak mucosal breakdown occurring between days 14 and 18.
Generally, the addition of hydrocolloid increased peak viscosity, lowered breakdown and reduced setback of the flour-hydrocolloid mixed paste.
Raman spectra of nanocrystals are characterized by the size-dependent phonon confinement effects which, for the case of Si and Ge, are manifested by asymmetric line broadening and a red shift of the peak due to breakdown of the k = 0 selection rule for Stokes scattering.
PV, peak viscosity; BD, breakdown; FV, final viscosity; SB, setback; PT, peak time.
The starch suspension was, constantly, stirred at 160 rpm and heated from 50 to 95°C, held at 95°C for 4 min and then cooled to 50°C for 4 min. The following variables were recorded in duplicate: peak viscosity (PV), breakdown (BK), trough (TG), final paste viscosity (FV), peak time (Pt), pasting temperature (PT), and setback (SB).
Region II extends from the potential of the third anodic voltammetric peak up to the breakdown potential.
The properties were expressed as the starting gel point temperature, peak viscosity (maximum viscosity), breakdown viscosity, (the difference between peak and minimum viscosity), and setback viscosity (the difference between minimum and final viscosity).
For a typical LOT test, once the peak pressure, or the breakdown pressure (P b), is reached, the pump is shut down to record the 10-s pressure reading and then, shut-in pressure is continuously recorded for more than 10 min, as shown in Fig. 2b.
