Making critical sections abortable is a promising approach to reducing priority inversions. To improve the schedulability of a system using abortable critical sections, the maximum number of abortions should be decreased. In this paper, we propose a real-time synchronization protocol named the ceiling abort protocol (CAP) which introduces a new priority-based abort scheme to the priority ceilin...

In a series of 2922 karyotyped spontaneous abortions, 62 were found to be trisomic for chromosome 13, 46 having a simple trisomy and 16 a translocation trisomy. The epidemiology of this series of trisomy 13 conceptuses is presented and compared to that of trisomy 13 ascertained from other populations. In most compared parameters the trisomy 13 spontaneous abortions are very similar. However, th...

The antiphospholipid syndrome was initially described in 1986. To reassess the validity of antiphospholipid antibodies in systemic lupus erythematosus (SLE), 95 patients with SLE were studied. Their antiphospholipid antibody profile was analysed and correlated with clinical findings such as thrombosis, abortions, or thrombocytopenia. A low prevalence of these antibodies was found (13 patients; ...

Analysis of statistics published since the Abortion Act showed that from 1972 about half the abortions carried out on residents of England and Wales had been performed within the National Health Service. Regional variations in the proportions of abortions performed within the NHS had persisted. In some health regions fewer abortions were being carried out than before. In 1975 about 40% of abort...

In the 2002 case Simat Corp v. Arizona Health Care Containment System, the Arizona Supreme Court ruled that the Arizona Health Care Containment System must pay for abortions when they are necessary to preserve the health of pregnant women in the system. In the case, the Court ruled that the Arizona Revised Statutes 35-196.02 and the Arizona Health Care Containment System (AHCCCS) policies, whic...

The authors estimated the number of clinically recognized pregnancies that occurred annually from 1981 to 1991 in the United States by type of outcome and by race. Estimates of the numbers of livebirths, induced abortions, ectopic pregnancies, and fetal deaths were obtained by using data from the Centers for Disease Control and Prevention in Atlanta, Georgia. The number of spontaneous abortions...

background: uterine rupture at the site of a previous cesarean scar is an uncommon but catastrophic complication of pregnancy, which is associated with significant maternal and fetal morbidity and mortality. case presentation: a 30-year old woman at 24th week of gestation and complaint of pain, contractions and spotting was admitted in royan institute in tehran, iran. she had a past medical his...

Robertsonian translocations (RT’s) are present in 0.1% of the general population and 1% of the infertile population. Two types of RT’s occur more frequently than all others, being 45,XX,rob(13;14)(q10;q10) and 45,XX,rob(14;21)(q10;q10) respectively. In the present report, an uncommon RT in a female with spontaneous repeated abortions is reported. Cytogenetic analysis of a couple with repeated a...

The U.S. Supreme Court struck down as unconstitutional an Akron, Ohio, ordinance regulating abortions because it interfered with a woman's right to obtain an abortion. The ordinance required that all abortions after the first trimester of pregnancy be performed in a hospital, prohibited physicians from performing abortions on unmarried minors under the age of 15 without parental consent or a c...
