This program calculates the spin lattice relation time (T1) and linewidth of a carbon atom relaxing by interacting with up 5 different nuclei by dipolar relaxation and or by Chemical Shift anisotropy (CSA) provided you know the rotational correlation time

In the program, an example from the field of nonlinear chemical dynamics is presented. Governing equation and reaction scheme can be found in G. Nicolis, Dynamique Chimique, Thermodynamique, cindoTetique et mdoTecanique statistique, Dunod, Paris 2005. We use the arc length continuation method to...

Molarity is a simple application that enables you to adjust a drinks' concentration. What determines the concentration of a solution? What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution...

Two tanks in are disposed in series. The level of tank 2 must be controlled despite a sine wave disturbance in the flow F3. This is achieved by changing the flow rate F0 of liquid to tank 1. The tanks areas are A1 and A2. Flow equations depends on constants K1 and K2. A proportional control with...
