Large quantities of waste tires are released to the environment in an undesirable way. The potential use of this waste material in geotechnical applications can contribute to reducing the tire disposal problem and to improve strength and deformation characteristics of soils. This paper presents a laboratory study on the effect of granular rubber waste tire on the physical properties of a clayey soil. Compaction tests using standard effort and consolidated-drained triaxial tests were run on soil and mixtures. The results conveyed an improvement in the cohesion and the angle of internal friction the clayey soil-granular rubber mixture, depending on the level of confining stress. These mixtures can be used like backfill material in soil retaining walls replacing the clayey soil due to its better strength and shear behavior and low unit weight. A numerical simulation was conducted for geosynthetic reinforced soil wall using the clayey soil and mixture like backfill material to analyzing the influence in this structure.

The term "cyberculture" permeates speech in various areas of contemporary society, referring to an issue that is extremely important, both because of its complexity, and because of its impact on cultural changes that affect all sectors of society today, and particularly education and educational processes. "Cyberculture" expresses the key elements involved in developing a digital culture that can be explored in all learning spaces and times. This article aims to analyze some of the complexities of cyberculture, using three works by the French scholar Pierre Lévy, namely: "Les technologies de l'intelligence" (1993), "Qu'est ce que le Virtuel?" (1996), and "Cyberculture" (1999). By detailing these complexities, we aim to make it easier for people and educational institutions to participate in the construction of the positive processes that cyberculture makes possible. Moreover, this fundamental discussion addresses society's understanding and, from this perspective, aims to identify possibilities and opportunities to improve educational processes.
