Implementation of a novel hybrid cord blood banking model within a private-public-partnership. [PDF]

Transfusion
Abstract Background Umbilical cord blood (UCB) stem cells can be collected at birth, cryopreserved, and used for transplantation in hematopoietic diseases. Typically, these stem cells are stored in public banks for allogeneic use or in private depositories for potential future utilization by the family.

DC Solid-State Circuit Breakers with Two-Winding Coupled Inductor for DC Microgrid

Energies, 2021
Ensuring a protection scheme in a DC distribution system is more difficult to achieve against pole-to-ground faults than in AC distribution system because of the absence of zero crossing points and low line impedance.

The employment effects of working time reductions: Sector‐level evidence from European reforms

Industrial Relations: A Journal of Economy and Society, Volume 62, Issue 3, Page 217-232, July 2023., 2023
Abstract In this paper, we exploit a panel of industry‐level data in European countries to study the economic impact of national reductions in usual weekly working hours between 1995 and 2007. Our identification strategy relies on the five national reforms that took place over this period and on initial differences across sectors in the share of ...
