Przemiany społeczno-kulturowe w okresie formowania się państwa piastowskiego w Wielkopolsce północno-zachodniej na podstawie materiałów archeologicznych z Santoka i Międzyrzecza

The strongholds of Santok and Międzyrzecz belong to major centers of the northwestern Great Poland in the period of formation the first Polish state. They were occupied in the same time but developed in entirely different conditions. The Santok stronghold is located on the borderland between Great Poland and Pomerania, at the place where two rivers – Warta and Noteć converge. A placement of the site within a communication net, in the border zone, and in a close proximity to the Baltic, facilitated contacts with distant regions leading to the development of strongholds in the Early Middle Ages. The stronghold was erected as a trade outpost in the 8th century. Archaeological excavations of different stratigraphic levels produced a very rich collection of artifacts originating from remote areas of the Baltic zone as well as eastern and southern Europe. This made possible to recognize subsequent phases of the settlement development and reflect on the role Santok played in the past. Międzyrzecz is situated on the Obra river in a long occupied area in western part of Great Poland. The stronghold was built in the first half of the 10th century. The analysis of the ceramic materials indicates that trajectory of pottery production departs from the developments reported for central Great Poland, but shows similarities to the Lower Lusatian region. This is indicative of connections among Slavic tribes inhabiting this region in the 9th century. In the following 10th century, Międzyrzecz was incorporated into the first Piast State and it became one of its most important centers of administration. The ramparts were rebuilt and widened. In the 11th century, the abbey was built near Międzyrzecz to facilitate missionary work among the pagan Slavs. The development of Santok and Międzyrzecz in the Early Middle Ages was determined by their placing in the very center of the communication net. The Piast dynasty attributed a defensive character to this part of the country, aimed at protecting its core from a military invasion coming from the west. These circumstances led eventually to the emergence and subsequent dynamic development of these cities

PISTAS PARA ENCONTROS NÃO PREMEDITADOS

Este artigo é a resposta a uma experiência de criação coletiva proposta pelos autores, denominada Prática de Arrumação, na programação do Rumos da Pesquisa em Artes Cênicas em Tempos de Crise II: Organizar a Vida - Viver na Arte, organizado pelo Grupo de Pesquisa Processos Criativos em Artes Cênicas, do Campus Curitiba II da Universidade Estadual do Paraná em Curitiba, entre os dias 22 e 27 de fevereiro de 2021. Os elementos constituintes de estratégias de criação e convivência são apresentados no texto através das descrições do espetáculo teatral And on the Thousandth Night..., do coletivo britânico Forced Entertainment; da leitura teatral de Carmelo Bene sobre a obra dramatúrgica de William Shakespeare, da performance Self Unfinished de Xavier Leroy e da relação traçada por Erin Manning entre tango e processo de individuação e coletividade. Entre essas descrições está a correlação entre trechos de pagode dos anos noventa e a descrição de Ariane Mnouchkine do processo de composição em teatro. Por fim, se descreve a prática de Arrumação, no evento de pesquisa, analisando seus momentos de preparação, execução e elaboração de seus efeitos em um texto escrito

Modified bibenzimidazole ligands as spectator ligands in photoactive molecular functional Ru-polypyridine units? Implications from spectroscopy

The photophysical properties of Ruthenium-bipyridine complexes bearing a bibenzimidazole ligand were investigated. The nitrogens on the bibenzimidazole-ligand were protected, by adding either a phenylene group or a 1,2-ethandiyl group, to remove the photophysical dependence of the complex on the protonation state of the bibenzimidazole ligand. This protection results in the bibenzimidazole ligand contributing to the MLCT transition, which is experimentally evidenced by (resonance) Raman scattering in concert with DFT calculations for a detailed mode assignment in the (resonance) Raman spectra

A fluorogenic cyclic peptide for imaging and quantification of drug-induced apoptosis

Programmed cell death or apoptosis is a central biological process that is dysregulated in many diseases, including inflammatory conditions and cancer. The detection and quantification of apoptotic cells in vivo is hampered by the need for fixatives or washing steps for non-fluorogenic reagents, and by the low levels of free calcium in diseased tissues that restrict the use of annexins. In this manuscript, we report the rational design of a highly stable fluorogenic peptide (termed Apo-15) that selectively stains apoptotic cells in vitro and in vivo in a calcium-independent manner and under wash-free conditions. Furthermore, using a combination of chemical and biophysical methods, we identify phosphatidylserine as a molecular target of Apo-15. We demonstrate that Apo-15 can be used for the quantification and imaging of drug-induced apoptosis in preclinical mouse models, thus creating opportunities for assessing the in vivo efficacy of anti-inflammatory and anti-cancer therapeutics

Pottery vessels from medieval and early modern period found during rescue excavation at Ujście in 2008

The article focuses on pottery vessels discovered during rescue excavation at Ujście, from layers of the former stronghold and city, dated to the period from the second half of the 10th century to the 16th century. The assemblage includes vessel fragments from early medieval period, partly formed as well as completely thrown on a potter’s wheel, and from the late medieval and early modern periods. This highly varied assemblage shows insight into pottery used by inhabitants of Ujście over several hundred years. The article, being only a preliminary analysis, also provides the impetus for the more detailed research on the pottery in the area located in the central River Noteć

The socio-cultural transformations in the period of the Piast state formation in north-western part of the Wielkopolska region (Greater Poland) on the basis of archaeological materials from Santok and Międzyrzecz

Early medieval combs from Santok

Abstract: The collection of combs from the stronghold in Santok is a set which varies in stylistic and formal terms, including products dated from the first half of the 9th century to the 13th century. A detailed analysis of the set of combs enabled changes in comb production over several hundred years to be identified and, on the other hand, helped to examine cultural links and methods of contacts which the residents of Santok maintained during this period
