[Lorenzo Bellini (16431704) and his discovery of the renal tubules].

In the article the biography of famous Italian doctor and anatomist Lorenzo Bellini who in his student years described a tubule system in the kidneys is reviewed. An authors translation of fragments of his work "Exercitatio anatomica de structura et usu renum" with the description of the discovery as well as the works of Marcello Malpighi "Opera posthuma", which stated the priority of this discovery to Bellini and not to Bartolomeo Eustachi, is provided. The evaluation of the medical and scientific activities of Bellini by his contemporaries is given.

A tricotage-like failure of nanographene.

The response of a nanographene sheet to external stresses was considered in terms of a mechanochemical reaction. The quantum chemical realization of the approach was based on the coordinate-of-reaction concept for the purpose of introducing a mechanochemical internal coordinate (MIC) that specifies a deformational mode. The related force of response is calculated as the energy gradient along the MIC, while the atomic configuration is optimized over all of the other coordinates under the MIC constant-pitch elongation.
