Autor: Torrico Bravo Juan Alfredo, Miranda Salvador, Cornellis Wim, Rojas Juan Carlos, Bezuijen Adam, Di Emidio Gemmina

Publikováno v: MATEC Web of Conferences, Vol 337, p 03004 (2021)

-Soil compaction in cropping systems, caused by the external pressure of machinery, creates impermeable layers that restrict water and nutrient cycles reducing agricultural production. To evaluate the matric suction effects on distribution with depth

Loading rate effect on mechanical properties of an unsaturated silty sand

Autor: Barahona Christian, Sandi Luis, Rojas Juan Carlos, Gemmina Di Emidio, Bezuijen Adam, Cornellis Wim

Publikováno v: MATEC Web of Conferences, Vol 337, p 01018 (2021)

This paper presents the results of an experimental study on the effects of testing rate on stress-strain behavior and volumetric changes of soil. A series of suction-controlled triaxial tests has been performed on reconstituted specimens of a silty s

An optimal convergent Collatz algorithm

Autor: Riano-Rojas, Juan Carlos

In this research, an optimal algorithm for the Collatz conjecture is presented. Properties such as the convergence of the algorithm and an equation that relates the algorithm to the classical Collatz conjecture are obtained. It is validated that the

Is it possible that the Goldbach's and Twins primes conjectures are true with an algebraic approach?

Autor: Riano-Rojas, Juan Carlos

In this paper, using an algebraic approach, it is intended to show that the Goldbach's and Twin primes conjectures are true, building, for each $m>2$, an isomorphism between posets. One of the posets is the set of coprimes less than $m$, while the ot
