Structural Formation of Alkali-Activated Materials Based on Thermally Treated Marl and NaSiO.

Modern materials science is aimed towards abandoning Portland cement in the production of building materials. The scientific novelty of this study lies in its being the first time a comprehensive study of the structure formation of alkali-activated materials (AAM) based on thermally treated marl and NaSiO is carried out. The tasks for achieving this goal were to characterize the thermally treated marl as a new binder, and to comprehensively research the microstructure, fresh, physical, and mechanical properties of the AAM based on the binder.

[Ureterosigmoidostomy with the formation of low pressure reservoir: history or operation of choice? 15 years of experience].

Aim: To examine the long-term outcomes of Mainz Pouch II ureterosigmoidostomy with the formation of a submucosal and extramural by Hassan (Hassan Abol-Enein) tunnels.

Materials And Methods: Mainz Pouch II ureterosigmoidostomies with the formation a submucosal tunnel (open-end technique) comprised group 1 (n=17) and with the formation of extramural ureteral implantation by Hassan - group 2 (n=15). The mean age of patients was 58+/-6.
