Release Notes for RacerPro 1.9.2 beta

• Performance improvements for the reasoning engine. For instance, RacerPro 1.9.2 can classify a version of Snomed (> 379000 concept names) in 13 minutes (Intel x86, 32bit, 2.4 GHz, 4GB, Mac OS X). It can also handle Aboxes with hundreds of thousands of individuals (see below for results on LUBM and UOBM) benchmarks. • Performance improvements for reading OWL files • Support for specific locale...

2,4-Dinitro-1-naphthol

In the title compound, C(10)H(6)N(2)O(5), the two fused rings are almost co-planar, with an r.m.s. deviation of 0.0163 Å. The nitro groups are oriented at dihedral angles of 2.62 (11) and 44.69 (11)° with respect to the plane of the parent fused rings. Intra-molecular O-H⋯O and C-H⋯O hydrogen bonds complete S(6) ring motifs. In the crystal, mol-ecules are linked into chains along [101] by inter...

Solvatochromism of â-Naphthol

Excitation and emission fluorescence spectra of 2-naphthol and 2-methoxynaphthalene were measured in a series of pure solvents. The spectral shifts are correlated by the Kamlet-Taft parameters (π*, â, and R). As judged from the π* dependence, both molecules have a negligibly small dipole moment in their ground electronic state, which increases in the excited (S1) state. However, the majority of...

Synchronous-derivative phosphorimetric determination of 1- and 2-naphthol in irrigation water by employing beta-cyclodextrin.

A room-temperature phosphorimetric (RTP) study of the inclusion process between 1- and 2-naphthol, beta-cyclodextrin (beta-CD) and 3-bromo-1-propanol as heavy atom pertuber has been performed. Experimental conditions were optimized for the formation of trimolecular complexes with lifetimes of 10.82 and 9.41 ms for 1- and 2-naphthol, respectively. A synchronous-derivative room-temperature phosph...
