Hybrid Discontinuous Galerkin methods with relaxed
No full textThe present work is the second part of a pair of papers, considering Hybrid Discontinuous Galerkin methods with relaxed H(div)-conformity. The first part mainly dealt with presenting a robust analysis with respect to the mesh size h and the introduction of a reconstruction operator to restore divergence-conformity and pressure robustness (pressure independent velocity error estimates) using a modified force discretization. The aim of this part is the presentation of a high order polynomial robust analysis for the relaxed H(div)-conforming Hybrid Discontinuous Galerkin discretization of the two dimensional Stokes problem. It is based on the recently proven polynomial robust LBB-condition for BDM elements, Lederer and Schöberl (IMA J. Numer. Anal. (2017)) and is derived by a direct approach instead of using a best approximation Céa like result. We further treat the impact of the reconstruction operator on the hp analysis and present a numerical investigation considering polynomial robustness. We conclude the paper presenting an efficient operator splitting time integration scheme for the Navier–Stokes equations which is based on the methods recently presented in Lehrenfeld and Schöberl (Comp. Methods Appl. Mech. Eng. 307 (2016) 339–361) and includes the ideas of the reconstruction operator

Leucocytozoon podargii Adlard & Peirce & Lederer 2002, n. sp.
No full textLeucocytozoon podargii n. sp. (gures 1–4) Type host. Podargus strigoides (Latham) (tawny frogmouth). Type locality. Currumbin, Queensland, Australia. Basis of description Macrogametocyte. Only round morphs occur, exhibiting the usual characteristics of the genus. Maximum diameter is about 15 m m (table 1). Cytoplasm is granular with occasional hyaline vacuoles present; nucleus generally oval in shape occupying a central to subcentral position but lacking a distinct karyosome. Maximum length of the host–parasite complex is 17 m m. The host cell nucleus forms a cap around the periphery covering about one-third (gure 1), but in most infections about half the parasites were observed without any remnant of the host cell nucleus (gure 2). Microgametocyte. Similar in size to the macrogametocyt e with the usual diOEerentiating characteristics. The nucleus is dispersed but has a distinctive karyosome which stains a deep red (gure 3). The prevalence of microgametocytes is very low with the ratio to macrogametocyte s being 1:50. Schizonts. In histopathology sections stained with H and E, the presence of schizonts was observed in skeletal muscle, lung and spleen. The schizonts in muscle were small compared to those in lung and spleen (gure 4). Megaloschizonts in lung and spleen tissue measured up to 163 m m in diameter and were characterized by cytomere formation with each section packed with merozoites. Hapantotype. IRCAH: G46311 2 (gametocytes) from Podargus strigoides, coll. Reid, 14 October 1999, Currumbin, Gold Coast, Queensland, Australia; IRCAH: G46311 3 (schizonts) from P. strigoides, coll. Lederer, 14 November 1998, Currumbin, Gold Coast, Queensland, Australia. Parahapantotype. IRCAH: G463114, G463115 and G463116 (gametoctyes) from P. strigoides, coll. Reid, 16 August 1999, 19 September 1999 and 10 October 1999; IRCAH: G46311 7 (schizonts) from P. strigoides, coll. Lederer, 14 November 1998, Currumbin, Gold Coast, Queensland, Australia. Other hosts. Probably occurs throughout the range of the Podargidae. Vectors. Unknown, but assumed to be simuliids. Etymology. Named after the genus of the type host. Comments. Leucocytozoon podargii is a parasite with only round morphs occurring in a small family of birds with a distribution restricted to the Australasian region. The inclusion of schizont stages is a bonus particularly as the presence of megaloschizonts occurs in the absence of second generation elongate morphs. In this respect L. podargii appears to have a life cycle similar to that of Leucocytozoon marchouxi Mathis and Leger (see Peirce et al., 1997). Nothing is currently known regarding the potential pathogenicity of L. podargii; the reason for euthanasia in this particular bird was related to causes other than the Leucocytozoon infection. The low prevalence of microgametocyte s in all the positive birds examined seems to be a characteristic of L. podargii infections. The earliest published record of leucocytozoids from the Podargidae was by Cleland (1915) who recognized Leucocytozoon sp. from P. strigoides from Eidsvold in southern Queensland. Later, Mackerras and Mackerras (1960) assigned leucocytozoids from the same host and locality to Leucocytozoon caprimulgi Kerandel originally described from the nightjar Caprimulgus fossii Hartlaub, a species with Afro-Tropical distribution. Their contention was that host relationships dictated conspecicity of the leucocytozoid. However, C. fossii is placed within the family Caprimulgidae (see Sibley and Monroe, 1990, 1993) while it has long been recognized that P. strigoides is a member of the Australasian-endemic bird family, Podargidae. Taking into account the established host-specicity at family level of Leucocytozoon spp. (see discussion in Bennett et al., 1991) and in the absence of any data to the contrary, we describe this species as L. podargii.Published as part of Adlard, R.

La communication du sens dans le contexte d'une tradution du français vers l'anglais d'un roman contemporain marocain,Une Via à Trois, par Bahaa Travelsi
No full textIncludes abstract.Includes bibliographical references.This thesis examines the communication of meaning in the context of the translation from French into English of a contemporary Moroccan novel, Une Vie à Trois, by Bahaa Trabelsi. To explore the notion of a faithful translation, the approach of the Ecole Superieure d'lnterpretes et de Traducteurs (ESIT) is examined. This approach, developed by Danica Seleskovitch and Marianne Lederer, emphasises the communication of meaning and the crucial role that interpretation plays in the act of translation. The project is composed of two parts - the practical application of the ESIT approach in the production of a translation of Une Vie à Trois and a theoretical study of the approach
