“DEPENDENCE OF THE BOND WORK INDEX ON THE FILLING RATIO AND TEST SIEVE APERTURE”. [PDF]
JES. Journal of Engineering Sciences, 2020 Knowledge of the grindability behavior of solid materials can be considered as an important factor for the design of their grindability systems. Bond work index (Wi) can be considered as one of the most important affecting factors in the design of grinding systems which express on the value of energy (kwh) consumed per ton of the ground ore.

Mechanistic analysis of TBM cutterhead-ground interaction under mud build-up effect
Frontiers in Earth ScienceIntroductionIn tunnel construction using TBMs, the complex mineral composition of strata and hydrogeological conditions often induce cutterhead mud build-up, which results in sharp increases in torque and thrust, thereby reducing excavation efficiency ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
