Study on Slagging Characteristics of Co-Combustion of Meager Coal and Spent Cathode Carbon Block

Energies, 2023
The harmless disposal of spent cathode carbon blocks (SCCBs) has become an urgent issue in the primary aluminum industry, and the disposal of SCCBs by co-combustion in pulverized coal boilers is expected to be the most effective treatment method.

5. On the Efficient Powers of Parturition [PDF]

Proceedings of the Royal Society of Edinburgh, 1872
There can be no doubt that, among the numerous matters at present occupying the attention of obstetricians, none is more important than the subject of this paper. So evident is the correctness of this statement that one cannot but wonder why attempts to arrive at the truth have been, so far as we know, delayed till the present day.
