Research on Mechanical Properties and Macroscopic Fracture Evolution of Rock with Different Joint Plane Features by Yongjiang Yu, Jingjing Liu, Pengbo Wang, Yuntao Yang, Shangqing Zhao

“…In this paper, triaxial compression tests are carried out on rock specimens with the different prefabricated joint planes, including different dip angles, roughness, confining pressure and surrounding rock strength, and the strength characteristics, failure modes, stress evolution laws, and crack propagation laws are revealed. The test results show that when the specimen is damaged, the strain, peak stress, and residual strength all increase with the increase of roughness, confining pressure, and strength of surrounding rock but decrease significantly with the increase of joint plane angle. …”

Effect of Strength Activity Index of Fly Ash on Concrete Performance by YIN Shaoqing, WANG Chunhui, WU Qianwen, FANG Peng

“…To ascertain the influence laws of the strength activity index of fly ash on concrete performance,we compound fly ash with different strength activity indexes for concrete performance tests and compare the influence of fly ash on mechanical properties,deformation properties,and durability of concrete.The experimental results reveal that within the range of the selected strength activity indexes of fly ash,the same design index of concrete all meets the design requirements,and the relevant indexes of hardened concrete and the strength activity index of fly ash maintain the same growth trend.…”

«Non muovere né l’anima senza il corpo, né il corpo senza anima». Le pratiche del ritmo nel “Timeo” e nelle “Leggi” di Platone by Simona Donato

“…In the Timaeus, precisely because of its kinetic and rhythmic dimension, the practice of imitating the rhythms of the stars is conceived by Plato as the main cure for the “imbalances” that the soul encounters when incarnated in a mortal body. In the Laws, on the other hand, Plato bases the theory of education through choral dance on the aforementioned capacity for rhythm and movement, activities that are associated to pleasure and joy.…”
