Species of the Genus Paroniella Fuhrmann, 1920 (Cestoda: Davaineidae) from Bulbuls (Passeriformes: Pycnonotidae): Redescription of P. perreti (Mahon, 1954) and Description of P. neolestes n. sp. from Africa.

Purpose: The purpose of the present study is to contribute to the knowledge on the diversity of cestodes of the genus Paroniella Fuhrmann, 1920 parasitising passerine birds of the family Pycnonotidae (bulbuls) in the Afrotropical Region. The only known species of this groups, Paroniella perreti (Mahon, 1954) from Pycnonotus tricolor (Hartlaub) in the Democratic Republic of the Congo, is poorly described. Therefore, it needed a detailed redescription in order to make a reliable comparison and provide differentiation among this species and newly-collected davaineid specimens.

Investigation of the Sensing Properties of Lanthanoid Metal-Organic Frameworks (Ln-MOFs) with Terephthalic Acid.

The solvothermal synthesis of LnClnHO with terephthalic acid (benzene-1,4-dicarboxylic acid, HBDC) produced metal-organic frameworks (LnBDC), [Ln(BDC)(HO)], where Ln = Sm, Eu, Tb, and Dy. The materials obtained were characterized by a number of physico-chemical techniques. The influence of the ionic radius of the lanthanides on the microstructural characteristics of the Ln-MOFs was evaluated by performing Rietveld refinement.

Luminescent Complexes of Europium (III) with 2-(Phenylethynyl)-1,10-phenanthroline: The Role of the Counterions.

New antenna ligand, 2-(phenylethynyl)-1,10-phenanthroline (PEP), and its luminescent Eu (III) complexes, Eu(PEP)Cl and Eu(PEP)(NO), are synthesized and characterized. The synthetic procedure applied is based on reacting of europium salts with ligand in hot acetonitrile solutions in molar ratio 1 to 2. The structure of the complexes is refined by X-ray diffraction based on the single crystals obtained.

Two new cestode species of the family Hymenolepididae Perrier, 1897 (Cyclophyllidea) from passerine birds in Ethiopia, with the erection of Citrilolepis n. g.

Two new cestode species of the family Hymenolepididae Perrier, 1897 are described from birds of the order Passeriformes at Wondo Genet, Ethiopia. Passerilepis zimbebel n. sp.

Pseudangularia gonzalezi n. sp. and Gibsonilepis swifti (Singh, 1952) n. g., n. comb. (Cestoda, Dilepididae) from the House Swift, Apus affinis (J.E. Gray) (Aves, Apodiformes) from Franceville, Republic of Gabon.

Nine specimens of Apus affinis (J.E. Gray) were studied at Franceville, Haut-Ogooué Province, Republic of Gabon, for the presence of helminth parasites.
