the test. This normal range represents an average value of healthy people who live in that area and will vary somewhat from lab to lab. Someone who is not taking warfarin would compare their PT test result to the normal range provided with the test result by the laboratory performing the ...
In the expanded guideline, the method of certified plasma preparation and method of INR value assignments are also described in detail. This guideline includes a recommended INR range that certified plasmas should cover and recommended number of certified plasmas required for local ISI calibration. A...
Methods: The value of a new simpler procedure to derive international normalized ratio (INR), the PT/INR Line, based on only five European Concerted Action on Anticoagulation (ECAA) calibrant plasmas certified by experienced centres has been assessed in two independent exercises using a range of ...
a patient with PTLab/INRLabwithin the normal range (blue solid line) and a patient on Coumadin therapy with elevated PTLab/INRLabvalues (red dotted line). For the normal patient, a constant low value of G was observed during the early phase of coagulation (t < 12 s) followed by...
Consider the following criteria when using decoupling capacitors: • Value and type of capacitor: A 0.1 F (100 nF), 10-20V capacitor is recommended. The capacitor should be a low-ESR device with a resonance frequency in the range of 200 MHz and higher. Ceramic capacitors are ...

Consider the following criteria when using decoupling capacitors: • Value and type of capacitor: A value of 0.1 µF (100 nF), 10V-20V is recommended. This capacitor should be a Low Equivalent Series Resistance (low-ESR), and have resonance frequency in the range of 20 MHz and higher....
(a), and perpendicular (b) to the crystal plane. The onset of the diamagnetic transition, defined as the superconducting transition temperatureTc, is shown by an arrow in both panels. (c,d) Isothermal magnetic field dependence of the magnetization,M(H), measured in a temperature range 2–...
The device compensates for the changes in input voltage, VIN and output voltage sensed by CSP pin, VCSP to achieve stable inner current loop operation over wide range of operating conditions. The value of RSLP is determined by the inductor, L and the switch current sense resistor, RIS and ...
