In the title compound, 0.75C12H14ClNO2·0.25C12H14ClNO, which is an adduct comprising 0.75 4-hy-droxy-piperidin-1-yl or 0.25 4-piperidin-1-yl substituents on a common (4-chloro-phen-yl)methanone component; the dihedral angles between the benzene ring and the two piperidine rings are 51.6 (3) and 89.5 (7)°, respectively. The hy-droxy-piperidine ring is in a bis-ectional oriention (bi) with the ph...

BACKGROUND The purpose of this study was to assess the repeatability and limits of agreement of corneal thickness values measured by a high-frequency ultrasound (Artemis-2), hand-held ultrasound pachymeter (DGH-500) and a specular microscope (SP-3000P). METHODS Central corneal thickness (CCT) was analyzed in this prospective randomized study that included 32 patients (18 men and 14 women) age...

In 1993, Mark Chase and 41 coauthors published phylogenetic analyses of two very large data sets of nucleotide sequences of the chloroplast gene rbcL, which encodes the large subunit of ribulose 1,5-bisphosphate carboxylase. Their paper was important for several reasons. These analyses were (and still are) among the largest ever attempted using parsimony. The assembly of such a large number of ...

Spin-polarized gaseous Bose-Einstein condensates were confined by a combination of gravitational and magnetic forces. The partially condensed atomic vapors were adiabatically decompressed by weakening the gravito-magnetic trap to a mean frequency of 1hertz, then evaporatively reduced in size to 2500 atoms. This lowered the peak condensate density to 5 x 10(10) atoms per cubic centimeter and coo...
