What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10? Since, the growth curve from day 2 to 10 won't be like the "Logistic curve" it might not follow logistic...

What techniques can I use to determine the miscibility of polymer blends?

The term miscibility refers to the single-phase state in thermodynamics. I do not mean the compatibility of different components. To determine the miscibility I know several techniques such as...

How to define tie constraint between rigid body and another part in dynamic explicit model of Abaqus?

Hi dear researchers I connected a rigid body into the part of my structure by tie constraint and then I added displacement to rigid body, in static general step every thing is fine and these two...

Does the circuit modeling for planar monopole antennas using Foster canonical forms give good approximation?

Hi researchers, I am searching for some accurate way to do the circuit modeling of planar CPW-fed monopole antennas. I have gone through the literature where mostly circuit modeling is done using...
