I'm working on implementing an old method for determination of cerebral blood flow in rats. I'm stuck in this equation! It is some years since I've worked with such formulas, and I can not get it to go up.

I really hope that there is one who will try .. X supposed to be equal to 0.058 / sec

**(A/B)=C* ((exp[X-T*0,32])-1)/X **
A=0,0026 nCi (Curie, measurement of radio-activity)

B=0,00152 mL/second (Millilitre/sec)

C=0,074 uCi/mL

T=20 seconds

**This is the actual equation(11) from the article with values and constants ..: **
Here, x is called k..
