In the first part of this series [Keith et al. (2004). Cryst. Growth Des. 4, 1009-1012; Mettes et al. (2004). Acta Cryst. A60, 621-636], a method was developed for constructing global phase diagrams (GPDs) for molecular crystals in which crystal structure is presented as a function of intermolecular potential parameters. In that work, a face-centered-cubic center-of-mass lattice was arbitrarily...

A60 class bulkhead penetration piece is a fire-resistance apparatus installed on compartments to protect lives and prevent flame diffusion in case of fire accident ships offshore plants. In this study, approximate optimization with discrete variables was carried out for the design an (A60 BPP) using various meta-models multi-island genetic algorithms. Transient heat transfer analysis evaluate p...

In vitro characterization and comparison of responses to different classes of biologically active compounds can increase the utility of bioassays. In this study, the relative potencies (REPs) of mixtures of polychlorinated naphthalenes (PCNs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs), to induce in vitro ethoxyresorufin-O-deethylase (EROD) in PLHC-1 fish hepa...

The theory of magnetic symmetry in quasicrystals, described in a companion paper [Lifshitz & Even-Dar Mandel (2004). Acta Cryst. A60, 167-178], is used to enumerate all three-dimensional octagonal spin point groups and spin-space-group types and calculate the resulting selection rules for neutron diffraction experiments.

-U4O9 is a superlattice structure based on the ̄uorite arrangement of UO2. The U atoms occupy positions close to those in UO2 and the additional O atoms are accommodated in cuboctahedral clusters of 43m symmetry, which are centred on the special 12-fold sites of the cubic space group I 43d. The structure has been re®ned from single-crystal neutron data in accordance with the procedure described ...
