The ammonites Lewesiceras peramplum Mantell and ?Lewesiceras sp. are reported from the Upper Cretaceous in the Nysa Kłodzka Graben; they date from the Middle Turonian and ?Coniacian, respectively. The Middle Turonian limestones of the Stara Bystrzyca quarry contain an abundant assemblage of inoceramids (Inoceramus cuvieri Sowerby and I. lamarcki Parkinson) and other bivalves, including oysters, as well as brachiopods and trace fossils. Micropalaeontological data show the presence of foraminifers and siliceous sponge spiculae, bryozoans, ostracods and fragments of bivalves and gastropods. The Middle Turonian calcareous deposits belongs to the upper part of the Inoceramus lamarcki Zone (late Middle Turonian) and were deposited on a shallow, subtidal offshore shelf. They overlie the Middle Turonian Bystrzyca and Długopole Sandstones, which represent foreshore-shoreface delta deposits. The fossil assemblage suggests a moderate- to low-energy, normal-salinity environment with occasionally an oxygen deficit.

My text is an attempt to apply Charles Taylor’s theory, dealing with the origins of the modern self, to Czech autobiographical literature originating in Romanticism. Taking a cue from Jean Starobinski and Philippe Lejeune’s concepts of modern autobiography, I analyse Karel Hynek Mácha’s personal diary from 1835 and try to find and emphasize its narrative and compositional aspects, which anticipate the poetics of modern poetic diaries.

Abstract. The paper presents a list of 437 verbs which have not been recorded in lexicography. As the source of reference, the author consulted a spelling dictionary of the Polish language, Wielki słownik ortograficzny PWN, 2nd edition, 2006. The concept of this paper originated from the wish to satisfy the curiosity after reading Indeks neologizmów [Index of Neologisms] prepared by Krystyna Waszakowa in her work Przejawy internacjonalizacji w słowotwórstwie współczesnej polszczyzny [Word-formative internationalisation processes in modern Polish]. The index contains a list of nouns. Given that K. Waszakowa did not take verbs into account (there are far (?) fewer neo-verbs than neo-nouns), the author decided to find out whether it is true that the number of verb neologisms is so small that their philological analysis is pointless from the point of view of research, vocabulary registration, etc. If nouns, such as podczłowiek, miniokupacja, redefinicja, are of interest, why not record the prefixal constructions of the do-, z-, od-, na-, w-, wy-, za-, od-, nad- etc. -robić type? The analysis included randomly selected texts from the „Rzeczpospolita” daily (without any thorough preparation with respect to the content; the texts available were sequentially analysed until the satisfactory result was obtained). The texts under review included an incomplete (it is virtually impossible to determine completeness in this case) electronic archive from the years 1993–2006.

This article is a continuation of a four-piece work describing the condition of soil in what has been broadly defined as central Poznań. This article presents the content of active forms of six chemical elements which tend to be absorbed by plants in biggest quantities. Relations between these chemical elements are discussed and indications are made of how to counteract the negative effects of deficits as well as overdoses of specific chemical elements in the substrate.

Informe de la realización de la gira educativa en los municipios de El Retiro y Medellín (Antioquia) para ampliar conocimientos técnicos en los procesos productivos del oficio de tejeduría en mimbre y de manejo de la madera desde la perspectiva de los criterios del proyecto del Sello de Calidad Hecho a Mano. Se indican las entidades colaboradoras con el desarrollo del evento. Se enumeran e indican los aspectos destacados de las visitas de evaluación realizadas a los talleres de producción artesanal de productos estructurados en madera y tejidos en mimbre y a los puntos de venta de cada una de las localidades, especificando cada uno de los temas en los que versaron los temas de las charlas y referentes de la evaluación de los aspectos y elementos funcionales. Igualmente se describe el proceso y resultado de la visita efectuada al Centro Nacional de la Madera del SENA. La síntesis descriptiva de cada actividad está complementada con fotografías (en blanco/negro).

Research on the construction of logical overlay networks has gained significance in recent times. This is partly due to work on peer-to-peer (P2P) systems for locating and retrieving distributed data objects, and also scalable content distribution using end-system multicast techniques. However, there are emerging applications that require the real-time transport of data from various sources to potentially many thousands of subscribers, each having their own quality-of-service (QoS) constraints. This paper primarily focuses on the properties of two popular topologies found in interconnection networks, namely k-ary n-cubes and de Bruijn graphs. The regular structure of these graph topologies makes them easier to analyze and determine possible routes for real-time data than complete or irregular graphs. We show how these overlay topologies compare in their ability to deliver data according to the QoS constraints of many subscribers, each receiving data from specific publishing hosts. Comparisons are drawn on the ability of each topology to route data in the presence of dynamic system effects, due to end-hosts joining and departing the system. Finally, experimental results show the service guarantees and physical link stress resulting from efficient multicast trees constructed over both kinds of overlay networks.
