COMPARISON OF EXPERIMENTAL TECHNIQUES FOR BIOCEMENTATION OF SANDS CONSIDERING HOMOGENEOUS VOLUME DISTRIBUTION OF PRECIPITATED CALCIUM CARBONATE

Comparison of experimental techniques for biocementation of sands considering homogeneous volume distribution of precipitated calcium carbonate

Microbially induced carbonate precipitation (MICP), or biocementation, consists in using microorganisms living in the soil to produce calcium carbonate (biocement).This mineral bonds the grains and therefore improves the soil hydro-mechanical properties.When using this technique, one of the challenges is to ensure homogeneous treatment in the entir

Strengthening copyright-1 Cipher Against Algebraic Attacks

In the last few years, several studies addressed the problem of data security in Mifare Classic.One of its weaknesses is the low random number quality.This causes SAT solver attacks to have lower complexity.In order to strengthen copyright-1 against SAT solver attacks, a modification of the feedback function with better cryptographic properties is
