My name is Odi, I am a student of Gadjah Mada University, Yogyakarta, Indonesia, Faculty of Agricultural Technology.

I am doing a research study on the angle of internal friction of cereals with direct shear test. The research will be used to write a thesis. I have difficulty finding supporting literature (book/article) with regard to the title.

I would like to ask you articles with respect to the title.
Items that I want to ask you are:

1. flow properties of cereals, how its if be measured with direct shear test.

2. efect of angle of internal friction toward handling equipment
( such as: bins and hopper).

3. data of angle of internal friction of several cereals
( such as : rice, corn, soy bean).

I look foward to hearing from you soon. Please send it
via e-mail : odi96@yahoo.com
Thanks for your help.
Sincerely yours,
