*** For d.cad.s,substantial d.sagreement has persisted.as to whether d.namic knee valgus is the cause of the majority of anterior cruciate ligament(ACL)injuries or rather the result of the ACL rupture.1 Consequently,great effort and.expense has gone into capturing 3-d.mensional kinetics and.kinematics from live athletes to d.ive in vitro and.in silico mod.ls of ACL injury in ord.r to elucid.te the actual mechanism of injury,as these factors have been d.monstrated.to be surrogates of intraarticular structural load.ng on the ACL.2,3 The elucid.tion of injury mechanisms for non-contact ACL injuries is of great med.cal value as such knowled.e consequently permits quantified.examination and.valid.tion of interventions and.their respective effectiveness in both prevention and.rehabilitation of these traumatic knee injuries.

This stud. focuses on the use of heavy fuel oil in construction material in Burkina Faso. Its mixture with silty or clayey soil is used.as a coating to reinforce the walls of raw earth constructions which are very sensitive to water. The interest of this stud. is to d.termine erod.bility, water content, while highlighting the influence of the porosity accessible by water on thermal d.ffusion in construction material containing heavy fuel oil. The heavy fuel oil was mixed.with a silty-clayey soil, in d.fferent proportions, and.water to make bricks samples on which tests were carried.out. At the end.of the experimental tests, it appears that the water content increases grad.ally, but not significantly with the ad.ition of heavy fuel oil, which causes a slight increase in the speed.of heat propagation through the material with red.ced.porosity, particularly those containing higher quantities of heavy fuel oil. Conversely, we note a good.performance of heavy fuel oil in terms of water resistance properties such as porosity accessible by water and.erod.bility. This allows us to conclud. that the mixture of heavy fuel oil and.silty-clayey soil used.as a coating material could.greatly red.ce water infiltration into the walls of housing constructions with raw earthen materials.
