Using factor analysis to distinguish between effective and ineffective aggregate stability indices [PDF]

open access: yes, 2012
Several existing aggregate stability indices are commonly used to represent aggregate stability of soil. Consequently, there is a need to determine how well these common indices characterize or represent aggregate stability.

Effect of water losses by evaporation and chemical reaction in an industrial slaker reactor

open access: yesBrazilian Archives of Biology and Technology, 2007
A dynamic model of the slaker reactor was developed and validated for Klabin Paraná Papéis causticizing system, responsable for white liquor generation used by the plant. The model considered water losses by evaporation and chemical reaction.

ツチ ノ コンシステンシー ゲンカイ ノ レオロジーテキ イギ [PDF]

open access: yes, 1980
【摘要】コンシステンシーという語は,一般にやわらかい物体が,外力をうけたときの変形または流動に対して抵抗する性質を評価するもので,材料のレオロジー的性質を示すものである.土のコンシステンシー測定については,力学的な試験法のかなりの部分をこれに含めて考えることもできるが,普通はコンシステンシー状態を区分するアツターベルグ限界が中心となろう.ここでは特にその中で,塑性領域の上下限を決める液性限界と塑性限界に焦点をしぼり,一見,全然似ていないこの二つの試験法が,何故に上下限を決めうるか,試験法の意義や ...

Divergent responses of aggregate breakdown by slaking to nitrogen forms in solution for contrasting soil types

open access: yesGeoderma
Aggregate stability strongly affects many soil processes and is critical to maintain sustainable agriculture. Aggregate breakdown is controlled by the interaction between soil intrinsic properties and solution characteristics.
