    The Apadana reliefs at Persepolis: An iconographic analysis with special emphasis on the identification and function of the gift-bearing delegations

    ENGLISH ABSTRACT: For many years, specific delegations on the façades of the Apadana at Persepolis posed an ongoing identification problem among scholars. Incongruities occurred in the identification of some of the groups – labelled Problem Groups in the current study. An attempt was made to try and solve the identification problem of specific delegations. It was necessary to look at the context in which these groups occurred, e.g., their physical world as well as their natural environment. The reliefs on the eastern façade of the Apadana was used in this study because they are still in a reasonably acceptable state. The combined iconographic analysis method (Panofsky/ Keel), as well as comparisons, were used to try and find a solution for the identification problem in the Problem Groups. After a detailed analysis and comparative research, the identification problem of the Problem Groups still evades answers except for one group. A totally different approach to the solving of the identification problem was suggested, and this deserves some attention from future scholars.

    First report and molecular characterization of the dagger nematode, Xiphinema oxycaudatum (Nematoda, Dorylaimidae) from South Africa
    (Pensoft, 2019-12-03) Daramola, Fisayo Y.; Knoetze, Rinus; Swart, Antoinette; Malan, Antoinette P.
    Plant-parasitic nematodes of the genus Xiphinema Cobb, 1913 comprise a complex group of nematode species, some of which are important vectors of plant viruses. During a field survey to determine the soil health of an abandoned honeybush (Cyclopia genistoides) monoculture, a high density of the dagger nematode, Xiphinema oxycaudatum Lamberti & Bleve-Zacheo, 1979 (Nematoda, Dorylaimidae), was observed in soil around the roots of honeybush plants in an abandoned farmland at Bereaville, an old mission station in the Western Cape province of South Africa. Soil samples were taken from the rhizosphere of plants and nematodes were extracted from the soil using a modified extraction tray method. Specimen of the dagger nematodes were processed for scanning electron microscopy, morphological and molecular analysis. Molecular profiling of the nematode species was done in order to give an accurate diagnosis and to effectively discriminate the nematode from other species within the Xiphinema americanum group. Phylogenetic analysis based on the D2D3 expansion segment of the 28S gene supported a close relationship of species within the americanum group, however, the protein-coding cytochrome oxidase (coxI) of the mitochondrial gene provided a useful tool for distinguishing the nematode from other species within the group. This study represents the first report of X. oxycaudatum from South Africa.
