Liriomyza valladaresae is similar to Liriomyza equiseti de Meijere in that the aedeagus forms a pair of sinuous tubules on the distiphallus, and it is differentiated mostly by the shape of the surstylus (with an apical spine in L. equiseti and no spines in L. valladaresae).Published as part of Monteiro, Nilton Juvencio Santiago, Barbosa, Rodrigo Rendeiro & Esposito, Maria Cristina, 2019, Agromyzidae (Diptera: Schizophora) in the state of Pará: new species and new records in Brazil, pp. 151-182 in Zootaxa 4624 (2) on page 175, DOI: 10.11646/zootaxa.4624.2.1, http://zenodo.org/record/325920

Esposito [collector]; 2 ♀, same location as holotype, 18-III-94, M.C. Esposito [collector]; 2 ♀, same location as holotype, 25-II-94, M.C. Esposito [collector]. Etymology. The specific epithet is based in the host-plant genus (Rolandra Rottb.). Distribution. Brazil (Pará). Remarks. The male genitalia of Calycomyza rolandrae sp. nov. is similar to male genitalia of Calycomyza michiganensis Steyskal and Calycomyza chilena Spencer, but C. rolandrae sp. nov. is distinguishable by the mesophallus curving downward apically and the projections of the distiphallus. Only Melanagromyza compositoides Spencer is known to mine leaves of Rolandra (Benavent-Corai et al. 2005), being C. rolandrae sp. nov. the first species of Calycomyza mining Rolandra species.Published as part of Monteiro, Nilton Juvencio Santiago & Esposito, Maria Cristina, 2017, New species and new records of Calycomyza Hendel (Diptera: Agromyzidae) in Brazil in Zootaxa 4338 (3), DOI: 10.11646/zootaxa.4338.3.11, http://zenodo.org/record/103694
Creep modelling of 316H stainless steel over a wide range of stress
No full textInvestigation of material creep behaviour in the diffusion controlled creep regime is often unfeasible because of the long duration associated with low stress levels. On the other side, extrapolation from higher creep rates usually provides inaccurate results because of the sharp change in the data trend as a result of the change in the governing deformation mechanism from dislocation to diffusion type controlled creep. Similarly, extrapolation based on creep models, which have been formulated and validated mainly for dislocation type creep (such power law creep with the creep exponent ranging from 6 to 9), underestimates the actual creep rate significantly. Recently, Bonora and Esposito (2010) developed a mechanism-based model (BE model) capable to account for deformation and damage mechanism occurring in creep. In this work the BE model was applied to AISI 316H stainless steel for which considerable creep data in both dislocation and diffusion temperature/stress controlled regime were available. Using the same data set, the predictive capabilities of several models were compared
