And it was made possible by the relationships and good will that OSF had generated over many, many years.
Overall, the puzzle remains: Why do some pathogens escape frequently and evolve rapidly, whereas others rarely generate escape variants and remain controlled over many years by the same vaccine?
The first major effort to generate musical sounds electrically was carried out over many years by an American, Thaddeus Cahill, who built a formidable assembly of rotary generators and telephone receivers to convert electrical signals into sound.
Cisco, an American network-equipment giant, has invested over many years in the technology needed to generate such data.
Under the deregulation plan, passed in 1996 with the expectation that it would be phased in over many years, utilities had to sell off their generating plants and then purchase power through a state-controlled exchange.
Mitochondrial DNA replicates frequently and independently of the nuclear genome [ 12], and over many years the potential for enhanced DNA damage from locally generated reactive oxygen species (ROS) may further enhance the accumulation of somatic mutations in the mitochondrial genome.
As illustrated by our cluster, secondary cases can generate tertiary cases, and together with late-secondary cases they can protract an TB outbreak over many years [ 3, 11- 14].
Because of the huge capital costs, stretched over many years, companies want some certainty over how much they might be paid for the electricity generated by their plants.
