Template driven self-assembly of the pentacene structure on the Si(553)-Pb surface

The self-assembly of the pentacene molecules on the Pb-ordered Si(553) surface is studied with scanning tunneling microscopy and density functional theory methods. Within the surface coverage up to a single monolayer, pentacene was found to form two different chain-like structures. They vary in molecular density, but both exhibit long-range, one-dimensional ordering with longer molecular axes aligned along step edges. The low-density phase consists of single discontinuous molecular rows and adapts the template surface periodicity, while the high-density phase features triple molecular chains with the unit cell determined by the length of the pentacene molecules. Such an arrangement of the molecules is controlled by a subtle balance between molecule–molecule and molecule–substrate interactions

The tentative reconstruction of evolution of the biogenic accumulation reservoir in Bydlin (Silesian-Cracovian Upland)

Osady torfowiska we wsi Bydlin na Wyżynie Śląsko-Krakowskiej poddano analizie geochemicznej, paleobotanicznej oraz malakologicznej. Torfowisko znajduje się, w obrębie rozległej depresji morfologicznej na obszarze krasu węglanowego. Sekwencja osadów została udokumentowana na podstawie wierceń o maksymalnej głębokości 4,20 m. W złożu torfowiska osady są bardzo zróżnicowane, występują zarówno torfy mszyste, turzycowo-mszyste i turzycowiskowe, jak i osady powstające w jeziorach, głównie w postaci gytii wapiennej, gytii ilasto-wapiennej oraz kredy jeziornej. Typ osadu świadczy o limnicznej przeszłości zagłębień w zachodniej i południowej części torfowiska. Na podstawie zawartości głównych składników litogeochemicznych budujących osady jeziorne i torfowe, składu i struktury malakofauny, przebiegu krzywych pyłkowych oraz składu botanicznego osadów torfowych dokonano charakterystyki cech paleośrodowiska, zrekonstruowano etapy rozwoju torfowiska oraz określono pozycję stratygraficzną osadów

Anthropological Perspectives on Gender Politics in/of Europe

Over the last few decades, the politics of gender and sexuality have turned extremely hostile across Europe. Long fought for rights and antidiscriminatory politics have come under heavy attack, while Gender Studies programs have been banned. In tandem, feminist arguments are being instrumentalized by right-wing movements so as to cement nationalist projects and racist positions. This turmoil regarding the politics of gender in Europe has become even more complex as gender, sexuality, and race find themselves used as markers of both progress and backwardness within the postcolonial, postsocialist European landscape reproducing old and creating new hierarchies within the societies and between them. Based on the 2021 conference “Troubling Gender: New Turbulences in the Politics of Gender in Europe,” organized by the Commission on Gender Research and Queer Anthropology of the German Association for European Ethnology and Empirical Cultural Analyses, this issue of Berliner Blätter hence assembles an array of analytical papers as well as polyvocal written discussions seeking to make sense of these developments as well as of their local and regional articulations and effects. The issue brings together queer/feminist voices and analyses from the Eastern and Western European contexts; furthermore, it examines the possibilities for solidarity across different positionalities and engages with diverse histories of struggle. The issue presents analyses informed by gender and queer theory, as mostly based on ethnographic research, and thus ultimately allows us to better understand the current conjuncture of the politics of gender and sexuality in and of Europe. With this, it partakes in the ongoing feminist and queer struggles to build a better future for all those concerned.Im letzten Jahrzehnt haben sich Politiken rund um Geschlechter und Sexualitätspolitik in ganz Europa äußerst feindselig entwickelt. Erkämpfte Rechte und eine antidiskriminatorische Politik sind massiv unter Beschuss geraten, Studiengänge der Geschlechterforschung wurden verboten. Gleichzeitig werden feministische Argumente von rechtsgerichteten Bewegungen instrumentalisiert, um nationalistische Projekte und rassistische Positionen zu zementieren. Noch weiter kompliziert wird die Situation dadurch, dass Geschlecht, Sexualität und Rasse in der postkolonialen, postsozialistischen europäischen Landschaft als Marker für Fortschritt und Rückständigkeit dienen, wodurch alte Hierarchien innerhalb der Gesellschaften und zwischen ihnen reproduziert und neue geschaffen werden. Ausgehend von der Konferenz „Troubling Gender: Neue Turbulenzen in der Geschlechterpolitik in Europa“, organisiert 2021 von der Kommission für Geschlechterforschung und Queere Anthropologie in der Deutschen Gesellschaft für Europäische Ethnologie und Empirische Kulturwissenschaft (DGEKW), bringt die Ausgabe der Berliner Blätter queere und feministische Stimmen und Analysen aus dem ost- und westeuropäischen Kontext zusammen. Gemeinsam versuchen sie, diese Entwicklungen, ihre lokalen und regionalen Artikulationen und Auswirkungen zu verstehen. Neben den geschlechter- und queertheoretisch fundierten Analysen, die sich größtenteils auf ethnografische Forschungen stützen, ergründen polyvokale, dialogisch geschriebene Beiträge die Möglichkeiten der Solidarität über verschiedene Positionen hinweg und zeigen die verschiedenen Geschichten von gender- und queerpolitischen Kämpfen und Epistemologien in Europa. Die Ausgabe ermöglicht so ein differenziertes Verständnis der aktuellen Situation der Geschlechter- und Sexualitätspolitik in und für Europa und hat damit teil an den laufenden feministischen und queeren Kämpfen um eine bessere Zukunft für alle Beteiligten.Peer Reviewe

SOLARIS National Synchrotron Radiation Centre in Krakow, Poland

The SOLARIS synchrotron located in Krakow, Poland, is a third-generation light source operating at medium electron energy. The first synchrotron light was observed in 2015, and the consequent development of infrastructure lead to the first users’ experiments at soft X-ray energies in 2018. Presently, SOLARIS expands its operation towards hard X-rays with continuous developments of the beamlines and concurrent infrastructure. In the following, we will summarize the SOLARIS synchrotron design, and describe the beamlines and research infrastructure together with the main performance parameters, upgrade, and development plans

HorTILLUS - a rich and renewable source of induced mutations for forward/reverse genetics and pre-breeding programs in barley (Hordeum vulgare L.)

TILLING (Targeting Induced Local Lesions IN Genomes) is a strategy used for functional analysis of genes that combines the classical mutagenesis and a rapid, high-throughput identification of mutations within a gene of interest. TILLING has been initially developed as a discovery platform for functional genomics, but soon it has become a valuable tool in development of desired alleles for crop breeding, alternative to transgenic approach. Here we present the HorTILLUS (Hordeum—TILLING—University of Silesia) population created for spring barley cultivar “Sebastian” after double-treatment of seeds with two chemical mutagens: sodium azide (NaN3) and N-methyl-N-nitrosourea (MNU). The population comprises more than 9,600 M2 plants from which DNA was isolated, seeds harvested, vacuum-packed, and deposited in seed bank. M3 progeny of 3,481 M2 individuals was grown in the field and phenotyped. The screening for mutations was performed for 32 genes related to different aspects of plant growth and development. For each gene fragment, 3,072–6,912 M2 plants were used for mutation identification using LI-COR sequencer. In total, 382 mutations were found in 182.2Mb screened. The average mutation density in the HorTILLUS, estimated as 1 mutation per 477 kb, is among the highest mutation densities reported for barley. The majority of mutations were G/C to A/T transitions, however about 8% transversions were also detected. Sixty-one percent of mutations found in coding regions were missense, 37.5% silent and 1.1% nonsense. In each gene, the missense mutations with a potential effect on protein function were identified. The HorTILLUS platformis the largest of the TILLING populations reported for barley and best characterized. The population proved to be a useful tool, both in functional genomic studies and in forward selection of barley mutants with required phenotypic changes. We are constantly renewing the HorTILLUS population, which makes it a permanent source of new mutations.We offer the usage of this valuable resource to the interested barley researchers on cooperative basis

Physico-geographical mesoregions of Poland : verification and adjustment of boundaries on the basis of contemporary spatial data

The programme of identification, cataloguing and evaluation of Polish landscapes, part of the implementation of the European Landscape Convention, has caused an increase in interest in physico-geographical regionalisation over recent years. The commonly accepted regionalisation of Poland developed by J. Kondracki (Kondracki & Richling 1994) is sufficient for work at an overview scale (e.g. 1:500,000), whereas its spatial accuracy is too low to make use of it for the purpose of Polish landscape cataloguing. The aim of this article is to present a more up-to-date and detailed division of Poland into mesoregions, adjusted to the 1:50,000 scale. In comparison with older work, the number of mesoregions has increased from 316 to 344. In many cases, some far-reaching changes in meso- and macroregions were made. Nevertheless, in most cases the previous system of units was maintained, with more detailed adjustment of boundaries based on the latest geological and geomorphological data and the use of GIS tools for the DEM analysis. The division presented here is a creatively developing new work aligning the proposals of the majority of Polish researchers. At the same time, it is a regionalisation maintaining the idea of the work developed by J. Kondracki as well as his theoretical assumptions and the criteria used to distinguish units, which makes it a logical continuation of his regional division
