Recombination vs. Mutation. Although genetic recombination was discovered following the formation of Darwin's theories of evolution, it is still claimed that mutations are the source of any natural variability.

Solid Lubricants / Dry Lubrication Graphite and molybdenum disulfide (MoS2) are the predominant materials used as solid lubricant. In the form of dry powder these materials are effective lubricant additives due to their lamellar structure. The lamellas orient parallel to the surface in the direction of motion.elf lubricating composites: Solid lubricants as PTFE, graphite, MoS 2 and some other anti friction and anti wear additives are often compounded in polymers and all kind of sintered materials. MoS 2 for example is compounded in materials for sleeve bearings, elastomere O-rings, carbon brushes etc.
