Sommario/riassunto |
|
This study aims to derive a qualitative model for energy requirements of the wood chipping process. A relationship is shown between energy requirements and properties of biomass, which is a quite variable material.The relationship between comminution machinery and energy which is necessary for the process is highlighted. The derivation of the |

model is focused on chipping, but it is generally possible to make it available for both different types of biomass (f. ex. agricultural residues)and different types of comminution machinery (f. ex. hammermills) by using different material properties adju |

Sommario/riassunto |
|
"A new translation of the primary Indian Buddhist text on Buddha nature, with Tibetan commentaries explaining how this text can be used to contemplate and realize one's own Buddha nature. "Buddha nature" (tathāgatagarbha) is the innate potential in all living beings to become a fully awakened Buddha. The book gives an overview of the sūtra sources of the tathāgatagarbha teachings and the different ways of explaining the meaning of this term. In particular, it includes new translations of the Mahāyānottaratantra (Ratnagotravibhāga), the primary Indian text on the subject, its Indian commentaries, and two (hitherto untranslated) commentaries from the Tibetan Kagyu tradition. Most important, the book investigates in detail the meditative tradition of using the Mahāyānottaratantra as a basis for Mahāmudrā instructions and the Shentong approach"-- |
