Trichogypsiidae Borojevic & Boury-Esnault & Vacelet 2000, n. fam.
No full textFamily TRICHOGYPSIIDAE n. fam. TYPE GENUS. — Trichogypsia Carter, 1871 by original designation. DIAGNOSIS. — Baeriida with a skeleton entirely formed by diactine spicules. DESCRIPTION We propose to put sponges that have affinities with the Baeriidae, but that have only diactine spicules in the family Trichogypsiidae. As discussed above, one of the characteristics of the Baeriida is the presence of small “mortar-shaped” diactines that make up either all of, or a large part of a specific portion of the skeleton. The Trichogypsiidae have large diactines, which are probably not homologous with “mortar-shaped” diactines. It is difficult to establish whether the absence of triactine spicules is a primitive condition or is a consequence of a secondary reduction of the skeleton. In the Leucosoleniida, diactines are the first spicules to be secreted, but it is not known if this is also true for the Baeriida. All the Trichogypsiidae are very poorly known, having been described in early studies from a small number of specimens; there are no recent studies that provide a detailed description of their cytology or biology. Up to now, the Trichogypsiidae have been only described from boreal or arctic regions.Published as part of Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2) on page 254, DOI: 10.5281/zenodo.539217
Baeriidae Borojevic & Boury-Esnault & Vacelet 2000, n. fam.
No full textFamily BAERIIDAE n. fam. TYPE GENUS. — Baeria Miklucho-Maclay, 1870 by original designation. DIAGNOSIS. — Baeriida with a choanoskeleton consisting of giant triactines, and/or of tetractines in no particular order, and/or of very numerous microdiactines. No traces of radial organization can be seen in the choanoskeleton. The cortical skeleton consists of triactines, giant diactines, and/or numerous microdiactines, and occasionally the basal actines of cortical giant tetractines. The choanoskeleton consists of scattered spicules similar to those observed in the cortex, to which numerous microdiactines can be added, or which can be entirely replaced by microdiactines. The exhalant aquiferous system is formed by ramified canals that have no tangential skeleton, being loosely or densely covered by harpoon-shaped pugioles and/or microdiactines.Published as part of Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2) on page 251, DOI: 10.5281/zenodo.539217
Polejaevia Borojevic & Boury-Esnault & Vacelet 2000, n. gen.
No full textGenus Polejaevia n. gen. TYPE SPECIES. — Polejna telum Lendenfeld, 1891 by monotypy. DIAGNOSIS. — Jenkinidae with a sylleibid organization. The cortex is supported by a layer of large tangential triactines. The choanoskeleton is composed of the unpaired actines of the subatrial triactines, and of rare small scattered triactines. DESCRIPTION In the system proposed by Lendenfeld (1891), the genus Polejna Lendenfeld, 1885 was used for sylleibid sponges with triactines and tetractines. The type species of Polejna, described originally as Leucilla uter Poléjaeff, 1884 is in fact a good species of Leucilla (Borojevic & Boury-Esnault 1987). Polejna is thus a junior synonym of Leucilla. Subsequently, Lendenfeld (1891) described in Adriatic a new species in the genus, Polejna telum Lendenfeld, 1891, that we consider to be different from Amphoriscidae and place now in the family Jenkinidae. A new name is thus required for the Jenkinidae with a sylleibid organization and triactines and tetractines such as Polejna telum, for which we propose Polejaevia. The position of Polejaevia in the family Jenkinidae is somewhat dubious, since small choanosomal triactines have been described in it and are represented in the illustration of the type species, distinguishing it from typical Jenkinidae. The size and distribution of the triactines is quite unusual, and as they are not reminiscent of the articulate choanoskeleton of the tubes of the Grantiidae, classification of P. telum in the genus Leucandra is impossible. Lendenfeld (1891) suggested that the triactines might be young cortical triactines. Secondary spicules may be found in the choanosome in the absence of any other skeleton, as seen in the genus Leucettusa Haeckel, 1872 (Borojevic et al. 1990). On the other hand, the organization of Polejaevia can be understood to be quite similar to Anamixilla: while in the former the additional triactines in the choanosome are new spicules, in Anamixilla the cortical spicules apparently invade the choanoskeleton. We propose that the genus should be maintained in the Jenkinidae until new specimens are examined. The description of Leucandra mawsoni Dendy, 1918 suggests that it might belong to Polejaevia. We have examined the specimens deposited in the British Museum (BMNH 20.12.9.95) and found that this species is a calcinean sponge, belonging to the genus Leucascus. Hence Polejaevia telum is the only known species belonging to this genus.Published as part of Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2) on page 232, DOI: 10.5281/zenodo.539217
Robert Esnault-Pelterie, 1881-1957
No full textEsnault-Pelterie followed a visionary path designing monoplanes with many features which would later become standard on modern planes. Esnault-Pelterie built engines as well. In 1904, he began glider research at Calais testing gliders based on the Wright\u27s designs. He also invented the first aileron. He was badly injured flying this R.E.P. No. 1 monoplane in 1908. Thereafter, he had others test his designs for him.https://corescholar.libraries.wright.edu/special_ms204_postcards/1010/thumbnail.jp
Leuclathrina Borojevic & Boury-Esnault 1987
No full textGenus Leuclathrina Borojević & Boury-Esnault, 1987 Diagnosis. ‘ Leucaltidae with leuconoid organization, the skeleton of which is limited exclusively to the cortex. The choanosome is completely devoid of a skeleton.’ (Borojević & Boury-Esnault 1987).Published as part of Voigt, Oliver, Ruthensteiner, Bernhard, Leiva, Laura, Fradusco, Benedetta & Wörheide, Gert, 2018, A new species of the calcareous sponge genus Leuclathrina (Calcarea: Calcinea: Clathrinida) from the Maldives, pp. 147-158 in Zootaxa 4382 (1) on page 151, DOI: 10.11646/zootaxa.4382.1.5, http://zenodo.org/record/118164
Philippe Esnault, historien du cinéma
No full textLa rencontre avec le cinéma d’André Antoine a peut-être décidé de la vocation d’historien du cinéma de Philippe Esnault. À la fin des années cinquante, les grandes synthèses de Sadoul, Lapierre, Leprohon, Jeanne et Ford étaient fraîchement parues, roboratives. La recherche sur l’histoire du cinéma pouvait paraître une activité réservée à des hommes nés avant 1910. Esnault avait suivi les cours de certains d’entre eux à l’IDHEC.

Breitfussia Borojevic & Boury-Esnault & Vacelet 2000, n. gen.
No full textGenus Breitfussia n. gen. TYPE SPECIES. — Ebnerella schulzei Breitfuss, 1896. DIAGNOSIS. — Jenkinidae with a simple tubular body and syconoid organization. The choanoskeleton is reduced to the unpaired actines of the subatrial triactines, and occasionally contains the proximal part of radial diactines. DESCRIPTION In the system proposed by Lendenfeld (1891), and followed by Breitfuss (1896), the genus Ebnerella of the subfamily Amphoriscinae was characterized by an inarticulate skeleton, containing diactines, triactines and/or tetractines. The species included by Lendenfeld (1891) in this genus belongs now to the genus Amphoriscus and Ebnerella is thus a junior synonym of Amphoriscus. Among the species described by Breitfuss (1896) in Ebnerella, E. kuekenthali belongs to the family Heteropiidae (Sycettusa), but a new name is needed for E. schulzei. In addition, species with an inarticulate choanoskeleton, described under the genus Grantia or Dermatreton, should be included in the new genus Breitfussia as now defined, such as Breitfussia (Grantia) vitiosa (BrØndsted, 1931) and Breitfussia (Dermatreton) chartacea (Jenkin, 1908). Breitfussia is known only from cold Arctic or Antarctic waters.Published as part of Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2) on page 230, DOI: 10.5281/zenodo.539217
FILET - a space for experimental art production
No full textFILET is a RESEARCH ORGAN situated in a physical space led by Rut Blees Luxemburg and Uta Kogelsberger (Newcastle University). FILET explores the production of new platforms for the creation, dissemination and networking of emergent strategies in contemporary art. Going beyond the conventions of an exhibition, FILET facilitates international exchanges (such as a co-operation with Kim Kim Gallery, (Seoul), as well as technologically innovative dissemination of research: for example, Professor Amanda Beech, Dean of Cultural Theory at Cal Arts, Los Angeles, collaborated with FILET for the life-streaming of a public symposia "How does Art think' in partnership with Newcastle University, New Center for Research and Arts Practice, New York. FILET is directed towards the global art and research community. Having its base in London, at the heart of the Digital Round-About, it is in close proximity to tech-city and the burgeoning dynamics of the local scene, while simultaneously collaborating with international artists, academics and researchers
