Translated Literature in the Bulgarian Middle Ages as a Social and Cultural Phenomenon

The study reviews the Medieval Bulgarian translations from Greek as a multi-centennial process, preconditioned by the constant contacts between Byzantium and its Slavonic neighbor and dependant on the historical and cultural circumstances in Medieval Bulgaria. The facts are discussed from the prospective of two basic determining factors: social and cultural environment (spiritual needs of the age, political and cultural ideology, translationsʼ initiator, centers of translation activities, degree of education/literacy). The chronological and typological analysis of the thematic and genre range of the translated literature enables the outlining of five main stages: (1) Cyrillo-Methodian period (the middle of the 9th centuty – 885) – reception of the corpus needed for missionary purposes; (2) The First Bulgarian Tsardom period (885–1018) – intensive translation activities, founding the Christian literature in Bulgaria; (3) The period of The Byzantine rule (1018–1185) – a standstill in the translation activities and single translations of low-level literature texts; (4) The Second Bulgarian Tsardom – the period of Asenevtsi dynasty (the late 12th and the 13th centuries) – a partial revision of the liturgical and paraliturgical books; (5) The Second Bulgarian Tsardom – the Athonite-Tarnovo period (the 14th – early 15th century) – extensive relations with Byzantium and alignment to the then-current Byzantine models, intensifications of the translations flow and a broad range of the translation stream.

Electron density building block approach for metal organic frameworks

A general introduction to the state of the art in modeling metal organic materials using transferable atomic multipoles is provided. The method is based on the building block partitioning of the electron density, which is illustrated with some examples of potential applications and with detailed discussions of the advantages and pitfalls. The interactions taking place between building blocks are summarized and are used to discuss the properties that can be calculated.

Mechanisms for the release of dopamine from turtle retina

The retinal circuitry underlying the release of dopamine was examined in the turtle, Pseudemys scripta elegans, using neurochemical release studies, anatomical techniques, and biochemistry. There was a dose- and calcium-dependent release of dopamine from turtle retinas incubated in $\sp3$H-dopamine after perfusion of the GABA antagonist bicuculline. This indicated that dopamine release was tonically inhibited by GABA. Other putative retinal transmitters were examined. Glutamate antagonists selective for hyperpolarizing bipolar cells, such as 2,3-piperidine dicarboxylic acid (PDA), caused dose- and calcium-dependent release of dopamine from the retina. In contrast, release was not observed after perfusion with 4-aminophosphonobutyric acid, a specific antagonist of depolarizing bipolar cells. This indicated that depolarizing bipolar cells were not involved in retinal circuitry underlying the release of dopamine in the turtle retina. The release produced by PDA was blocked by bicuculline, indicating a polysynaptic mechanism of release. None of the other agents tested, which included carbachol, strychnine, dopamine uptake inhibitors, serotonin, tryptamine, muscimol, melatonin, or dopamine itself produced release.^ The cells capable of the release of dopamine were identified using both uptake autoradiography and immunocytochemical localization with dopamine antisera. The simplest circuitry based on these findings is signal transmission from photoreceptors to hyperpolarizing bipolar cells then to GABAergic cells, and finally to dopaminergic amacrine cells. ^
