Series multi-cell converters introduced more than ten years ago provide many degrees of freedom like the possibility to distribute the voltage constraints among series-connected switches and to improve the output waveforms. Direct control laws make perfect use of them during transient behaviors, but leads to disorderly and imperfect steady-state operations. This paper deals with some solutions for...
The possible use of marrow progenitor cells derived from peripheral blood was hypothesized almost 30 years ago 1 and confirmed two decades later with the first efforts to collect and preserve human stem cells from peripheral blood during remission after chemotherapy for hematological malignancy. 2,3 During the past 10 years the use of autologous progenitor cells mobilized...
The possible use of marrow progenitor cells derived from peripheral blood was hypothesized almost 30 years ago and confirmed two decades later with the first efforts to collect and preserve human stem cells from peripheral blood during remission after chemotherapy for hematological malignancy. During the past 10 years the use of autologous progenitor cells mobilized to the peripheral blood has gradually...
