Although transformation of the myeloproliferative neoplasms (MPNs) to acute POSTERS myeloid leukemia (AML) is well documented, development of an MPN in patients previously treated for, and in remission from, AML is exceedingly rare.A case is described in which a patient was successfully treated for AML and in whom a JAK2 V617F-positive MPN was diag
The interaction in the solar wind between two TOYS OTHER coronal mass ejections (CMEs) is investigated using numerical simulations.We show that the nature of the interaction depends on whether the CME magnetic structures interact, but in all cases the result is an equilisation of the speed of the two CMEs.In the absence of magnetic interaction, the
Renewable energy sources such as solar, wind and geothermal are proposed as an alternative to fossil fuels whose excessive use causes global warming.The most popular one Boots of the renewable energy sources is considered as solar energy due to the fact that required energy is provided by the sun entire year around the world.Solar energy systems co
