ON THE “SOLAR SYSTEM SMALL BODIES” ASTROPLATE PROJECT OF THE UKRAINIAN VIRTUAL OBSERVATORY
2019
The UkrVO Joint Digital Archive of astro- plates and the newest digitized data processing services al- lowed us to form a new approach for the creation of catalogs of astrometric and photometric characteristics of the Solar System bodies. Given this, the main goal of this approach was not only to complete the processing with the best possi- ble accuracy of high-quality and unprocessed earlier photo- graphic observations of the Solar System bodies but also to find new original data from these observations. As a result, more than 6,500 new astrometric positions and stellar magnitudes of asteroids, and 3,036 positions of outer planets (Pluto, Uranus, Neptune, Saturn, Jupiter) and their satelli…
Urban transport policy transfer in central and Eastern Europe
2008
Abstract European Territorial Cooperation is one important context in which partners from across the whole of Europe meet and learn from each other. Naturally, the involvement of partners from Central and Eastern European (CEE) countries in this process is increasing as a consequence of the expansion of Europe, particularly the accession of ten new EU member states in 2004, and two more in 2007. Various examples can be found where CEE countries are seeking to catch up politically and economically by drawing lessons from policies in more developed countries. The uncertainties of policy-making in some of these countries have made policy transfer a particularly attractive option, as politician…
Joseph Conrad-Korzeniowski, an English Writer with a Polish Soul: Joseph Conrad’s Polish Heritage
2018
The article presents a portrait of Joseph Conrad-Korzeniowski, an English writer with a Polish soul. Conrad—the last Polish Romantic—did not only manage to introduce Polish dreams and longings into English (and Western) literature, but also transformed the Polish experience into a universal one. Writing about exotic, faraway places, he disseminated myths concerning Polish national identity, chivalric tradition and the Polish Eastern Borderland atmosphere and ethos. Conrad, a very demanding writer, never presents ready-made answers, nor does he offer simple solutions to the problems of his protagonists. Moreover, everybody can understand Conrad in their own personal way, for he is perceived …
Le calamità ambientali nel tardo medioevo europeo: realtà, percezioni, reazioni
2010
For some time historiography has set itself the objective of studying the ways in which European society in the late Middle Ages and the early Modern Age has related to environmental disasters, addressing the perceptions and the reactions, the strategies implemented by the governments, and the repercussions on the religious mentality. In this way it has identified a sphere of investigation that is an authentic multi-disciplinary and inter-disciplinary workshop, engaging historians of institutions, culture and mentality. At the conference held in San Miniato, Italian and European historians compared notes on this subject, addressing it from different points of view and taking into considerat…
Social Pedagogy as an offer of master’s studies in Poland after the Second World War (1945-1950)
2021
The article presents graduate programs (Masters level) in the field of social pedagogy offered by Helena Radlińska and her colleagues at the University of Łódz after WWII. Socio-Pedagogical studies established at the Department of Social Pedagogy at the University of Łódz were supposed to prepare educational, social, and cultural workers in time of revival of Poland after 1945. The example of the educational model created at that time can serve as an inspiration in the development of contemporary programs of education rooted in the Polish socio-pedagogical tradition.
Journalists’ Associations as Political Instruments in Central and Eastern Europe
2017
This editorial provides the overall context for the five cases—three national and two international—covered in this thematic issue. While the cases are from Central and Eastern Europe (CEE), they highlight fundamental questions of journalism everywhere, including contradictions between freedom and control, professionalism and politics, individual and collective. The associations of journalists serve as very useful platforms to study these questions, especially at historical turning points when the whole political system changed, as happened twice in CEE after World War II.
Essential oils of Chiliadenus lopadusanus (Asteraceae).
2013
The essential oils from the leaves and flowers of Chiliadenus lopadusanus growing on Lampedusa Island were obtained by hydrodistillation and analyzed by GC-MS. The major component was camphor (39.4% in the leaves and 24.0% in the flowers), followed in the leaves by torreyol (6.7%), t-cadinol (5.2%) and 1,8-cineole (3.8%), while in the flowers by t-cadinol (15.2%), t-muurolol (5.1%) and torreyol (4.5%). Among the compounds identified, several seem to play a role in antibacterial, antifungal, allelopathic and spasmolytic activity. In addition, several compounds identified in this study seem to influence the attraction of Megachile (Eutricharaea) apicalis (Megachilidae) and Halictus (Seladonia…
Native and planted forest species determine different carbon and nitrogen pools in Arenosol developed on Holocene deposits from a costal Mediterranea…
2016
In a coastal Mediterranean area, the effects of two native [Quercus ilex (Holm), Alnus glutinosa and Fraxinus oxycarpa (Hygro)] and one planted [Pinus pinaster (Pine)] forest species on both content and quality of organic C and total N pools in Arenosols was assessed. Three soil profiles per each forest cover were opened and sampled. Total N in the organic layers was not affected by forest covers, whereas total organic C ranged from 36.1 to 63.2 Mg ha−1, being organic layers under Hygro those with the highest contents. Total organic C in the first 50 cm of mineral soil was 64 Mg ha−1 under Holm and 36.7 and 37.6 Mg ha−1 under Pine and Hygro, respectively. Soil covered by Holm and Hygro stor…
The nucleosome-remodeling ATPase ISWI is regulated by poly-ADP-ribosylation.
2008
ATP-dependent nucleosome-remodeling enzymes and covalent modifiers of chromatin set the functional state of chromatin. However, how these enzymatic activities are coordinated in the nucleus is largely unknown. We found that the evolutionary conserved nucleosome-remodeling ATPase ISWI and the poly-ADP-ribose polymerase PARP genetically interact. We present evidence showing that ISWI is target of poly-ADP-ribosylation. Poly-ADP-ribosylation counteracts ISWI function in vitro and in vivo. Our work suggests that ISWI is a physiological target of PARP and that poly-ADP-ribosylation can be a new, important post-translational modification regulating the activity of ATP-dependent nucleosome remodel…
Properties of PP/MWCNT-COOH /PP composites made by melt mixing versus solution cast /melt mixing methods
2015
An approach on improvement of the properties of polypropylene / carbon nanotube (PP/CNT) composites is reported. PP blend compositions with carboxylic acid functionalized multi-walled carbon nanotubes (MWCNT-COOH) at filler content 1.0 wt.% were researched. One part of the composites was manufactured by direct thermoplastic mixing PP with the filler, but the other one was made from solution casted masterbatch with the following thermoplastic mixing. An increase of mechanical properties (Young's modulus, storage modulus and tensile strength), compared to an increase of glass transition temperature indicated a reinforcement effect of CNTs on PP matrix, determined from the tensile tests and di…
