S-type lectins occur also in invertebrates: high conservation of the carbohydrate recognition domain in the lectin genes from the marine sponge Geodi…
1993
The marine sponge Geodia cydonium contains several lectins. The main component, called lectin-1, is composed of three to four identical subunits. The subunits of the lectins were cloned from a cDNA library; two clones were obtained. From the deduced aa sequence of one clone, LECT-1, a mol. wt of 15,313 Da is calculated; this value is in good agreement with mass spectrometric analysis of 15,453 +/- 25 Da. The sequence of another clone, LECT-2, was analysed and the aa sequence was deduced (15,433 Da). The two subunits have a framework sequence of 38 conserved aa which are characteristic for the carbohydrate-binding site of vertebrate S-type lectins. Clustering of lectin sequences of various s…
MRSA ST22-IVa (EMRSA-15 clone) in Palermo, Italy
2010
Summary: Epidemic spread of methicillin-resistant Staphylococcus aureus (MRSA) strains carrying the Staphylococcal Chromosomal Cassettes (SCC) mec type IV is being increasingly reported in many geographical areas. A survey to determine the prevalence and characteristics of MRSA SCCmec IV isolates identified in four general hospitals in Palermo, Italy, was carried out. During the period February–June 2009, SCCmec type IVa has been found in 12 out of 94 isolates. Nine isolates from all hospitals and all strains from a NICU outbreak occurring in the same period were attributed with the ST22-IVa (EMRSA-15) clone. In our setting, due to the changing MRSA epidemiology, detection of SCCmec IV coul…
Epidemic dissemination of Salmonella enterica spp. enterica serovar Bovismorbificans in southern Italy in the years 1989-1991.
1994
Epidemic strains of Salmonella enterica subsp. enterica serovar Bovismorbificans isolated in southern Italy during the years 1989-1991 were submitted to a molecular epidemiological study in comparison with isolates identified in the years 1980-1988 in the same geographic area. Genomic DNA fragments obtained by digestion with BglI or Eco RI hybridized with Escherichia coli rRNA to produce three distinct, but highly related patterns. Ribotype 1, which had never been identified before 1989, was found to characterize most of the strains identified between 1989 and 1991. Such a finding supports the hypothesis of emergence and spread of a new bacterial clone associated with the increased number o…
GPU accelerated Monte Carlo simulations of lattice spin models
2011
We consider Monte Carlo simulations of classical spin models of statistical mechanics using the massively parallel architecture provided by graphics processing units (GPUs). We discuss simulations of models with discrete and continuous variables, and using an array of algorithms ranging from single-spin flip Metropolis updates over cluster algorithms to multicanonical and Wang-Landau techniques to judge the scope and limitations of GPU accelerated computation in this field. For most simulations discussed, we find significant speed-ups by two to three orders of magnitude as compared to single-threaded CPU implementations.
Upper limits on the isotropic gravitational-wave background from Advanced LIGO and Advanced Virgo's third observing run
2021
We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs. Unlike in previous observing runs in the advanced detector era, we include Virgo in the search for the GWB. The results are consistent with uncorrelated noise, and therefore we place upper limits on the strength of the GWB. We find that the dimensionless energy density $\Omega_{\rm GW}\leq 5.8\times 10^{-9}$ at the 95% credible level for a flat (frequency-independent) GWB, using a prior which is uniform in the log of the strength of the GWB, with 99% of the sensitivity comi…
Metal Dependence on the Bidirectionality and Reversibility of the Singlet Energy Transfer in Artificial Special Pair-Containing Dyads
2017
International audience; The demetalation of a precursor dyad, 3, built upon a zinc(II)-containing artificial special pair and free-base antenna, leads to a new dyad, 4, for singlet energy transfer composed of cofacial free-base porphyrins (acceptor), [Fb](2) bridged by a 1,4-C6H4 group to a free-base antenna (donor), [Fb]. This dyad exhibits the general structure [M](2)-C6H4-[Fb], where [M](2) = [Fh](2), and completes a series reported earlier, where [M](2) = [Mg](2) (2) and [Zn](2) (3). The latter dyads exhibit a bidirectional energy-transfer process at 298 K for 2 and at 77 K for 3. Interestingly, a very scarce case of cycling process is observed for the zinc-containing dyad at 298 K. The…
Embodied graffiti and street art research
2021
Graffiti and street art research (GSAR) has become more acknowledged within the academic discourse; however, it has much to gain from theorising its methodological aspects. As a multidisciplinary field, GSAR has mostly used qualitative research methods, exploring urban space through methods that range from visual recordings to ethnography, emphasising the researchers’ reflexivity. This qualitative approach has, however, paid little attention to the role of embodied practices. In this paper we discuss how embodied methodologies provide multisensory research results where the experienced moments, the participant’s and researcher’s senses, cognition and mobility in urban spaces are connected.…
Changes in the standard of living of chosen countries that joined the European Union after 2004
2018
W artykule poruszona została problematyka zmian poziomu życia w państwach członkowskich Unii Europejskiej, które przystąpiły do struktur unijnych po 2004 r. Podjęta została próba uchwycenia oddziaływania polityki UE na wyrównywanie poziomu życia w państwach członkowskich. Przyjęty w badaniu okres obejmuje lata 2004-2015. Za początek okresu badawczego przyjęty został rok 2004, ze względu na fakt, że w tym właśnie roku nastąpiło największe w historii UE rozszerzenie jej struktur. W badaniu wykorzystano metody taksonomiczne, w szczególności wskaźnik rozwoju Hellwiga jako syntetyczny miernik poziomu życia.
Can Money buy Love? : The Impact of the Cohesion Policy of the European Union on European Identity
2019
Master's thesis Innovative governance and public management ME523 - University of Agder 2019 This Master thesis explores the relationship between Cohesion policies of the EU and European identity. After first describing the history and context of Cohesion policies of the EU, the literature on European identity studies is reviewed. This discussion develops an economic utilitarian argument, that citizens in Europe develop their identification with the EU partly on rational considerations, and that the added quality of life provided by investments of the EU would positively influence their European identity. This effect is expected to be different throughout European regions.The hypothesesare …
Changes in the Standard of Living in the EU Member States between 2005 and 2012, with Particular Emphasis on Poland and the Czech Republic
2016
This chapter is dedicated to the issues relating to changes in the standard of living recorded in 25 EU countries, in particular in Poland and the Czech Republic. Given the availability of comparable and relevant statistical data, the standard of living was studied between 2005 and 2012. The study was conducted with the use of taxonomic method – Hellwig’s synthetic measure. The results indicated that in 2012 Poland and the Czech Republic recorded a growth in the standard of living compared to 2005. Between 2005 and 2008, Poland was in the group of countries with a relatively low standard of living. It was not until the 2012, that it entered the group of countries with a moderate standard of…
