Hydrogen Sorption

Both LaF3 and the in situ formed LaH2 enable the reversible hydrogen sorption in NaBH4. Comparative studies show that La-B phases play the major role for the regeneration of NaBH4 in both the NaBH4+LaF3 and the NaBH4+LaH2 composites while the substitution of F- for H- results in more favorable thermodynamics in the NaBH4+LaF3 composite.

Similarities And Differences

The story of Lot is one of many shared by the Qur'an and the Torah, and Lot's offer of his two daughters to his people is presented in a similar way in the two books. This article compares the status of Lot in the Qur'an and Torah, and explores the moral dimensions of his character, and what scholars of the two religions make of this story. The significance of the episodes in which Lot offers his daughters to his people lies in the similarities and differences of the accounts given in the two books and the fact that, in both the past and the present, this story has presented moral problems and criticism has been leveled at Lot. Context is crucial in understanding this story, and exploration of the ways in which Lot and his people are presented is also useful in terms of comparative studies of the two scriptures. This article is divided into three sections: the first explores the depiction of Lot in the two texts, the second explores his moral limitations, and the third discusses the interpretations of various exegetes and scholars of the two books. Although there are similarities between the Qur'anic and Talmudic accounts of this episode, it is read differently by scholars from the two religions because of the different contexts of the respective accounts.

ABSTRACT In 15 cases of therapeutic abortion by laparotomy the placenta was disconnected from the foetus and perfused in situ with tracer amounts of radioactive dehydroepiandrosterone (DHA), dehydroepiandrosterone sulphate (DHAS), androst-4-ene-3,17-dione (A), testosterone (T) and 17β-oestradiol (OE2). Analysis of the placentas, perfusates and urine samples revealed an extensive aromatisation of DHA, A and T; more than 70% of the radioactive material recovered was phenolic, and at least 80 % of this phenolic material was identified as oestrone (OE1), 17β-oestradiol (OE2) and oestriol (OE3), the latter being detected only in the urine. Comparative studies indicated that A and T were aromatised somewhat better than DHA and that all three unconjugated steroids were aromatised to a much greater extent than DHAS. Radioactive OE1 and OE2 were isolated and identified in the placentas and perfusates, but no OE3, epimeric oestriols, or ring D ketols could be detected in these sources, not even when human chorionic gonadotrophin (HCG) was added to the blood prior to perfusion. Lack of placental 16-hydroxylation was also apparent when OE2 was perfused. Regardless of the precursor perfused, there was three times more OE2 than OE1 in the placenta and three times more OE1 than OE2 in the perfusate. This was also the case following perfusion with OE2. The results are interpreted as suggesting the existence in the pregnant human of a placental »barrier« limiting the passage of circulating androgen. The barrier consists of a) limited ability to transfer directly DHAS and b) an enzymic mechanism resulting in the rapid and extensive aromatisation of the important androgens DHA, A and T.
