Separate reactions of [Th{N(CH2CH2NSiMe2But)2(CH2CH2NSi(Me)(But)(?-CH2)]2 (1) with [Re(?5-C5H5)2(H)] (2) or [Ru(?5-C5H5)(H)(CO)2] (3) produced, by alkane elimination, [Th(TrenDMBS)Re(?5-C5H5)2] (ThRe, TrenDMBS = {N(CH2CH2NSiMe2But)3}3-), and [Th(TrenDMBS)Ru(?5-C5H5)(CO)2] (ThRu), which were isolated in crystalline yields 71% 62%, respectively. Complex ThRe is the first example a molecular Th-Re...

This paper proposes an approach to constructing a 3-D paper-m ad e ob ject from a crease pattern, a set of line segm ents (creases) on a sheet of paper w hich is usually prod uced w hen a paper-m ad e ob ject such as origam i is unfold ed . F irst, a coord inate transform ation m ethod from 2 -D crease patterns to 3-D space is proposed . S ince faces (form ed b y the creases) m ore than tw o ar...

Critical views are presented on some nucleo-cosmochronological questions. Progress has been made recently in the development of the 187 Re-187 Os cosmochronometry. From this, there is good hope for this clock to become of the highest quality for the nuclear dating of the Universe. The simultaneous observation of Th and U in ultra-metal-poor stars would also be a most interesting prospect. In co...

A b st r a c t — What has not yet come clearly into focus in the current exploration of the mind/body problem is how the unique features of dre a m ing cons c i o u s n ess might contribute to the ong o ing dialogue. Following a brief hist o r ical pe rs pe c t i ve, a th e o ry of dre a m ing as no c t u rnal social vigilance is p res e n t ed that takes into account both the genetic and socia...

Th, Th, U and U compositions of several deep-sea solitary corals, mainly the species Desmophyllum cristagalli, were determined by thermal ionization mass spectrometry (TIMS). It is possible to obtain high precision ages on modern pristine corals that have low [Th] (5 to a few hundred ppt). However, because older deep-sea corals tend to have higher [Th] compared to surface corals, and the initia...
