Evidence has not however been received that this was a residence with the cell design or in the analyzed samples. Having said that, the inverse character could on the other hand be very important in the sector of pressure layout according to Janssen's equations, which make use of the values of helpful angles, especially in applications with supplies having even worse flowability.
