Previous studies have shown that overall fibrinolytic activity in blood follows a diurnal rhythm with a peak in the morning and a trough in the evening. The purpose of this study was to determine which fibrinolytic factor(s) was responsible for this diurnal rhythm. Resting and postvenous occlusion tissue-type plasminogen activator (t-PA) activity, resting t-PA antigen, and resting plasminogen a...

For a provably recursive function f : N→ N of PA one can consider the notion of f -consistency for PA, Conf (PA) := ∀xCon(PA f(x)), where PA k denotes the fragment of PA with induction restricted to Σk formulae. It was shown in [8] that for a certain slow growing function f the strength of PA + Conf (PA) lies strictly between PA and PA + Con(PA). Letting τBH be the Bachmann-Howard ordinal, this...

Introduction: Paediatric patients deserve special attention because of the higher radiation risks compared with adults. The main purpose of this study is to determine patient dose and diagnostic reference level for Paediatric through Entrance Surface Dose (ESD) calculations in common X-ray examination and to establish Paediatric national DRLs in digital radiography in Iran. <...

A multiple dose, parallel group study was conducted to assess for a drug-drug interaction between the pyronaridine/artesunate (PA) combination antimalarial and ritonavir. Thirty-four healthy adults were randomized (1:1) to receive PA for 3 days or PA with ritonavir (100 mg twice daily for 17 days, PA administered on Days 8-10). Pharmacokinetic parameters for pyronaridine, artesunate, and its ac...

Current RF power amplifier (PA) linearization techniques are presently being investigated to improve PA linearity and power efficiency. One such linearization technique, Cartesian feedback (CFB), makes use of analog feedback to linearize a nonlinear plant (Figure 1). The commanded baseband symbol, I and Q, are compared to the symbol being transmitted by the PA, the baseband symbol is predistort...
