Photo Ionization

A new grid of ionizing fluxes for O-type and Wolf-Rayet stars is presented for use with evolutionary synthesis codes and analyses of single star H ii regions. A total of 230 expanding, non-LTE, line-blanketed model atmospheres have been calculated for five metallicities (0.05, 0.2, 0.4, 1 and 2 Z⊙). We have used the wm-basic code of Pauldrach et al. (2001) for O-type stars and the cmfgen code of Hillier & Miller (1998) for WR stars. The stellar wind parameters are scaled with metallicity for both O-type and WR stars. The ionizing fluxes of the new models, incorporated into the evolutionary synthesis code STARBURST99 (Leitherer et al. 1999), are compared with the predictions of the original starburst99 and Schaerer & Vacca (1998) for an instantaneous burst. We find large changes in the output ionizing fluxes as a function of age, especially below the He+ edge. In contrast to previous studies, nebular He ii λ4686 will be at, or just below, the detection limit in low metallicity starbursts during the WR phase. The new models have lower fluxes in the He i continuum for Z ≥ 0.4 Z⊙ and ages ≤ 7 Myr because of the increased line-blanketing. The accuracy of the new model atmosphere grid is tested by constructing photo-ionization models for an H ii region where the ionizing flux is provided by an instantaneous burst. The new models occupy the same region in nebular diagnostic diagrams as the observational data of Bresolin et al. (1999), particularly during the WR phase. The new model grid and updated starburst99 code can be downloaded from http://www.star.ucl.ac.uk/starburst.

Multiple Levels

Goldberg’s (2006) bass-ackwards approach to elucidating the hierarchical structure of individual differences data has been used widely to improve our understanding of the relationships among constructs of varying levels of granularity. The traditional approach has been to extract a single component on the first level of the hierarchy, two components on the second level, and so on, treating the correlations between the components on adjoining levels akin to path coefficients in a hierarchical structure. This article proposes three modifications to the current approach with a particular focus on examining associations among all levels of the hierarchy: 1) identify and remove redundant components that perpetuate through multiple levels of the hierarchy; 2) (optionally) identify and remove artefactual components; and 3) plot the strongest component correlations among the remaining components to identify their hierarchical associations. Together these steps can offer a simpler and more complete picture of the underlying hierarchical structure among a set of observed variables. The rationale for each step is described, illustrated in a hypothetical example, and then applied in real data with specific methodological recommendations. The results are compared to the traditional bass-ackwards approach, and basic code is provided to apply the proposed modifications in other data.

A method for the shear design of wide beam ribbed slabs is proposed. The method modifies the current UK code design method for solid slabs by applying a shear area factor which reduces the area of the code critical shear perimeter to take account of the loss of shear area from that of a solid slab. The proposed method gives good agreement with test data for internal column situations, and underestimates the strength at edge columns. The conservativeness in relation to edge columns arises because of an empirical assumption made in the basic code method for solid slabs and is not due to the modification that it is proposed for wide beam ribbed slabs.

The Given

Abstract A description is given of a method for computing the influence coefficients in bending of a nonuniform cantilever beam using a basic code devised for the National Bureau of Standards electronic automatic computer SEAC. The given data for a particular problem are n, the number of stations at which influence coefficients are desired; EI0, EI1, … EIn, the bending stiffnesses at the root and at successive stations; and l1, l2, … ln, the distances between these stations. The basic code can be used in any case where the number of stations n is fewer than 23. In an example for a beam having 9 stations, the computing time was 3 min.
