Track theory has been applied to an earlier suggestion, that the supralinearity of TLDs at high gamma-ray doses is due to pre-existing 1-hit and 2-hit trap structures, to calculate high-LET response. Measured 60Co dose responses for peaks 5 and 6 in LiF (TLD700) were decomposed to yield parameters characterizing each peak as a two-component c-hit mixture. One value of “trap radius” was assigned...

the effect of gibberellic acid (ga3) spraying on some characteristics of cyclamen flowering trend during the second flowering year was investigated. ga3 sprays were applied in concentrations of 0, 20, 30, 40, and 50 mg/l. the trial was carried out as a randomized complete design of three replications. the total flower count, flower count during the flowering peak, days from spraying to flowerin...

In several chaotic systems, the value of a peak (relative maximum) of a variable and its time of occurrence can be predicted, with very good approximation, from the value of the previous peak. This property, which is called peak-to-peak dynamics and which basically relies on the low-dimensionality of the chaotic attractor, allows to approximately model the system in a very compact form by a pea...

Introduction: The different factors that affect the camera uniformity of Single Photon Emission Computed Tomography (SPECT) technique have been analyzed including peak shift (%) and window width of energy. The effect of peak shift and window width on SPECT image uniformity has been investigated using a point source to perform intrinsic flood images. Methods:</stro...
