No full textTentative criteria for the design and installation of electrical power systems subject at seismic hazard
No full textThis paper discusses the need to study the criteria for the design and installation of electrical power systems in buildings subject to seismic hazards. Nowadays, all the recommended seismic requirements (according to the Uniform Building Code [UBC], Structural Engineers Association of California [SEAOC] and National Earthquake Hazards Reduction Program [NEHRP]) do not specifically take into account the electrical or technological power systems. This paper analyzes the problems an earthquake can cause with regard to the functional reliability and continuity of supply of electrical power systems. Therefore, it proposes design and installation requirements, to be graduated according to building occupancy categories. Basically, the criteria relative to the installation of the electrical equipment are an appropriate extension of those general static ones for nonstructural components. Their consideration is essential for the settlement of the design criteria, which, as far as the configuration and the size of the electrical power system are concerned, aim at limiting the same installation problems. Other general design criteria, designed as a guarantee for supply continuity and power system reliability, have a particular use in these appliance
Structures of two encapsulated cobalt(III) complexes containing cyclo-triphosphate
No full textThe conformational and packing properties of two encapsulated cobalt(III) complexes containing cyclo-triphosphate have been investigated. Compound (I), (1,3,6,8,10,13,16,19-octaazabicyclo[6.6.6]icosane)cobalt(III) cyclo-triphosphate-water (2/7) has the trivial name cobalt(III) sepulchrate cyclo-triphosphate-water (2/7) and chemical formula [Co(sep)](P3O9).3.5H(2)O. The cation shows an lel(3) geometry very similar to those found in other sepulchrate complexes. The packing motif is given by one-dimensional chains of alternating cations and anions running along the z direction and cross-linked by hydrogen-bonded water molecules. Compound (II) is [tris(aminoethylaminomethyl)amine]tris(ethylenediamine)dicobalt(III) di(cyclo-triphosphate) octahydrate, and has the chemical formula [Co(sep')(P3O9)][Co(sep')(0.72)(en(3))(0.28)(P3O9)].8H(2)O (where sep' = C9H27N7). Pseudotranslational symmetry is found, perturbed by the substitutional disorder sep'/en(3). B-centering is therefore simulated involving the anions and water molecules. The crystal packing is similar to that found for compound (I), but the regularity of the chains is broken by the disorder

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
