Symbolism Versus Abstraction: Architectural Representation in a Post-Modern Society
This thesis poses an investigation into the work of Karl Friedrich Schinkel and Mies van der Rohe as elements of a formal architectural tradition in Berlin; It proposes the institution of an architecture based up on a chosen set of historical models, with the aim of providing one possible foundation for architectural renewal (of unified Berlin) implying cultural continuity. To this end, the thesis poses an investigation into the representative qualities of architecture while examining the informative potential of artifact
On the Convergence of the Density of Terras' Set
The Collatz Conjecture's connection to dynamical systems opens it to a
variety of techniques aimed at recurrence and density results. First, we turn
to density results and strengthen the result of Terras through finding a strict
rate of convergence. This rate gives a preliminary result on the Triangle
Conjecture, which describes a set nodes that would dominate . Second, we extend prior
arguments to show that the construction of several classes of measures imply
the bounded trajectories piece of the Collatz Conjecture
The Early Carboniferous (Mississippian) ammonoids from the Chebket el Hamra (Jerada Basin, Morocco)
The ammonoids from the Argiles de Timimoun of Timimoun (Early and Middle Viséan; Gourara, Algeria)
A new ammonoid fauna from theGattendorfia-Eocanites Genozone of the Anti-Atlas (Early Carboniferous; Morocco)
From the eastern part of the Tafilalt (Anti-Atlas, Morocco), rich assemblages of ammonoids of the Gattendorfia-Eocanites Genozone are described. The detailed investigation of an outcrop near Mfis in the south-eastern Tafilalt yielded a diverse fauna with 24 species, of which 13 are new. The genus Weyerella n. gen. is newly erected with Weyerella protecta n. sp. as type species. Furthermore, the following new species are described: Paragattendorfia aboussalamae n. sp., Acutimitoceras hollardi n. sp., Acutimitoceras posterum n. sp., Acutimitoceras mfisense n. sp., Acutimitoceras occidentale n. sp., Imitoceras oxydentale n. sp., Kazakhstania nitida n. sp., Zadelsdorfia debouaaensis n. sp., Weyerella minor n. sp., Eocanites simplex n. sp., Eocanites rtbeckeri n. sp., and Eocanites dkorni n. sp. The state of preservation of the ammonoids as limonitic steinkern specimens permits a detailed study of sutures and conch ontogeny.Aus dem östlichen Tafilalt (Anti-Atlas, Marokko) wird eine Ammonoideen-reiche Abfolge aus der Gattendorfia-Eocanites Genus-Zone beschrieben. Ein im Detail untersuchtes Profil bei Mfis hat eine individuenreiche und diverse pelagische Fauna mit 24 Arten geliefert, von denen 13 neu sind. Die Gattung Weyerella n. gen. wird mit Weyerellaprotecta n. sp. als Typusart aufgestellt. Weitere neue Arten sind: Paragattendorfiaaboussalamae n. sp., Acutimitocerashollardi n. sp., Acutimitocerasposterum n. sp., Acutimitocerasmfisense n. sp., Acutimitocerasoccidentale n. sp., Imitocerasoxydentale n. sp., Kazakhstanianitida n. sp., Zadelsdorfiadebouaaensis n. sp., Weyerellaminor n. sp., Eocanitessimplex n. sp., Eocanitesrtbeckeri n. sp. und Eocanitesdkorni n. sp. Die in Limonit erhaltenen Steinkerne erlauben eine Detailuntersuchung der Lobenlinien und der Gehäuse-Ontogenie.doi:10.1002/mmng.20060000
Tournaisian (Early Carboniferous/Mississippian) ammonoids from the Ma'der Basin (Anti-Atlas, Morocco)
The ammonoids from the Grès du Kahla supérieur of Timimoun (Middle-early Late Tournaisian; Gourara, Algeria)
Late Givetian ammonoids from Hassi Nebech (Tafilalt Basin, Anti-Atlas, southern Morocco)
The Hassi Nebech area of the SE Tafilalt (Tafilalt Basin, Anti-Atlas, Morocco) yielded the richest and most diverse late Givetian ammonoid fauna on a global scale. Above the distinctive regional "Lower Marker Bed" (<i>Synpharciceras clavilobum</i> Zone), abundant loosely collected limonitic specimens derive from hypoxic shales of the <i>Taouzites taouzensis</i> to <i>Petteroceras errans</i> zones. The ontogenetic morphometry and intraspecific variability of a total of 30 species representing five families, the Acanthoclymeniidae, Taouzitidae, Pharciceratidae, Petteroceratidae, and Tornoceratidae, are documented. New taxa are: <i>Pseudoprobeloceras praecox</i> n. sp., <i>Scaturites minutus</i> n. gen. n. sp., <i>Darkaoceras velox</i> n. sp., <i>Pharciceras decoratum</i> n. sp., <i>Ph. fornix</i> n. sp., <i>Ph. subconstans</i> n. sp., <i>Ph. involutum</i> n. sp., <i>Lunupharciceras incisum</i> n. sp., <i>Transpharciceras procedens</i> n. gen. n. sp., <i>Stenopharciceras progressum</i> n. sp., <i>Pluripharciceras</i> n. gen. (type species: <i>Synpharciceras plurilobatum</i> Petter, 1959), <i>Plu. orbis</i> n. sp., <i>Synpharciceras frequens</i> n. sp., <i>Lobotornoceras bensaidi</i> n. sp., <i>Nebechoceras eccentricum</i> n. gen. n. sp., and <i>Phoenixites lenticulus</i> n. sp. The documentation of conch and particularly suture ontogeny and intraspecific variability necessitates a revised diagnosis for ten taxa. <i>Manticoceras pontiformis</i> Termier & Termier, 1950, <i>Probeloceras costulatum</i> Petter, 1959, and <i>Pseudoprobeloceras nebechense</i> Bensaïd, 1974 are regarded as subjective junior synonyms of <i>Ps. pernai</i> (Wedekind, 1918). <i>Sandbergeroceras acutum</i> Termier & Termier, 1950 is a subjective synonym of <i>Taouzites taouzensis</i> (Termier & Termier, 1950). <i>Pharciceras applanatum</i> Bensaïd, 1974 is transferred to <i>Extropharciceras</i>. Other forms (<i>Ph</i>. aff. <i>tridens</i>, <i>Ph</i>. cf. <i>subconstans</i> n. sp., <i>Extropharciceras</i> n. sp. 2, <i>Ex</i>. cf. <i>arenicum</i>, <i>Ex</i>. cf. <i>applanatum</i>, <i>Synpharciceras</i> sp., <i>Plu</i>. cf. <i>plurilobatum</i>) are described in open nomenclature.
