- Fighting between the national army, alongside Russian mercenaries and Rwandan forces, and elements of the Coalition of Patriots for Change (Coalition des patriotes pour le changement, CPC) decreased, but was at times intense.

- Quartz (Wikipedia)
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth’s continental crust, behind feldspar.
