Twin-shaft screw-type expanders offer a high potential for energy conversion in the lower and medium power range, for instance as expansion engines in Rankine cycles for exhaust heat recovery. With regard to minimizing internal leakages and lubricating moving machine parts, an auxiliary liquid or liquid working fluid, for example in organic Rankine cycles(More)
Uterine rupture is one of the most serious complications of pregnancy, causing maternal and perinatal death. An increased risk of uterine rupture is associated with uterine scars caused by previous cesarean section, myomectomy, hysteroscopic procedures and ART treatment.

Umbilical cord blood (CB) as a source of haematopoietic stem cells for allogeneic transplantation has many advantages over bone marrow and peripheral blood, however, a main limitation to its use in clinical setting is cell numbers. This study aimed to assess the impact of mother/neonatal factors on the quality of CB units, collected for allogeneic(More)
