In this paper we consider the relation between the volume deceleration parameter obtained within the Buchert averaging scheme and the deceleration parameter derived from supernova observation. This work was motivated by recent findings that showed that there are models which despite having Λ = 0 have volume deceleration parameter qvol < 0. This opens the possibility that back-reaction and avera...

placenta increta, a rare complication of pregnancy, is associated with significant postpartum hemorrhage often requiring emergency hysterectomy. we report a case of conservative management, with a combination of parenteral methotrexate, serial ultrasound and β-hcg assessment. serum β-hcg levels were undetectable after 8 weeks of therapy. a scan at 6 months showed complete involution of the uter...
