Optical spectroscopy of X-ray sources in the Taurus molecular cloud: discovery of ten new pre-main sequence stars
2008
We have analyzed optical spectra of 25 X-ray sources identified as potential new members of the Taurus molecular cloud (TMC), in order to confirm their membership in this SFR. Fifty-seven candidates were previously selected among the X-ray sources in the XEST survey, having a 2MASS counterpart compatible with a PMS star based on color-magnitude and color-color diagrams. We obtained high-resolution optical spectra for 7 of these candidates with the SARG spectrograph at the TNG telescope, which were used to search for Li absorption and to measure the Ha line and the radial and rotational velocities; 18 low-resolution optical spectra obtained with DOLORES for other candidate members were used …
There is no clam with coats in the calm coast: delimiting the transposed-letter priming effect.
2009
In this article, we explore the transposed-letter priming effect (e.g., jugde–JUDGE vs. jupte–JUDGE), a phenomenon that taps into some key issues on how the brain encodes letter positions and has favoured the creation of new input coding schemes. However, almost all the empirical evidence from transposed-letter priming experiments comes from nonword primes (e.g., jugde–JUDGE). Indeed, previous evidence when using word–word pairs (e.g., causal–CASUAL) is not conclusive. Here, we conducted five masked priming lexical decision experiments that examined the relationship between pairs of real words that differed only in the transposition of two of their letters (e.g., CASUAL vs. CAUSAL). Result…
Do transposed-letter similarity effects occur at a prelexical phonological level?
2006
Nonwords created by transposing two letters (e.g., RELOVUTION) are very effective at activating the lexical representation of their base words (Perea & Lupker, 2004). In the present study, we examined whether the nature of transposed-letter (TL) similarity effects was purely orthographic or whether it could also have a phonological component. Specifically, we examined transposed-letter similarity effects for nonwords created by transposing two nonadjacent letters (e.g., relovución– REVOLUCIÓN) in a masked form priming experiment using the lexical decision task (Experiment 1). The controls were (a) a pseudohomophone of the transposed-letter prime ( relobución– REVOLUCIÓN; note that B an…
Dynamic of the genetic structure of bacterial and fungal communities at different developmental stages of Medicago truncatula Gaertn. cv. Jemalong li…
2006
International audience; The genetic structure of bacterial and fungal communities was characterized in the rhizosphere of Medicago truncatula Gaertn. cv. Jemalong line J5 at five developmental stages (three vegetative and two reproductive stages), and in three compartments (bulk soil, rhizosphere soil and root tissues). The genetic structure of microbial communities was determined by cultivation-independent methods using directly extracted DNA that was characterized by automated ribosomal intergenic spacer analysis (ARISA). Principal component analyses (PCA) indicate that, for all developmental stages, the genetic structure of microbial communities differed significantly by compartment, wit…
Nymphaeetum candidae Miljan 1933 in Poland
2011
This paper presents the distribution, floristic composition and ecological requirements of the water plant community <em>Nymphaeetum candidae</em> Miljan 1933, belonging to the <em>Potametea</em> class. Until present this community has been reported only from north-eastern Poland. During present studies it was stated also in the south-western part of the country. <em>Nymphaeetum candidae</em> is considered to be a rare and endangered plant community in several countries of Central Europe.
Scirpetum radicantis Hejný in Hejný et Husák 1978 em. Zahlh. 1979, a plant association new to Poland
2011
The paper presents a rush community new to Poland - <em>Scirpetum radicantis </em>Hejny in Hejny et Husak 1978 em. Zahlh. 1979, belonging to the <em>Phragmition </em>alliance. It was discovered in fishponds near Olesno in Silesia (SW Poland). The floristic composition and the ecological requirements of this association are presented in the paper. <em>Scirpetum radicantis </em>is considered to be a very rare and endangered plant community in Europe.
Sleep quality does not mediate the association between chronodisruption and metabolic syndrome
2020
ABSTRACTAimsThe objective of the present work was to determine to what extent sleep quality may mediate the association between CD, metabolic syndrome (MS) and body composition (BC).MethodologyCross-sectional study which included 300 adult health workers, 150 of whom were night shift workers and thereby exposed to CD. Diagnosis of MS was made based on Adult Treatment Panel III criteria. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Body mass index (BMI), fat mass percentage, and visceral fat percentage were measured as indicators of BC. Data were analyzed using logistic, linear regression and structural equation models.ResultsThe odds of health workers exposed to CD t…
Polycomb-like 2 Associates with PRC2 and Regulates Transcriptional Networks during Mouse Embryonic Stem Cell Self-Renewal and Differentiation
2010
SummaryPolycomb group (PcG) proteins are conserved epigenetic transcriptional repressors that control numerous developmental gene expression programs and have recently been implicated in modulating embryonic stem cell (ESC) fate. We identified the PcG protein PCL2 (polycomb-like 2) in a genome-wide screen for regulators of self-renewal and pluripotency and predicted that it would play an important role in mouse ESC-fate determination. Using multiple biochemical strategies, we provide evidence that PCL2 is a Polycomb Repressive Complex 2 (PRC2)-associated protein in mouse ESCs. Knockdown of Pcl2 in ESCs resulted in heightened self-renewal characteristics, defects in differentiation, and alte…
Kulisy niedoszłego procesu sądowego Stowarzyszenia Polskich Kombatantów w Wielkiej Brytanii z "Tygodnikiem Polskim" w latach 1948-1949
2013
In 1948 members of the Polish Ex-Combatants Association charged the editor of Tygodnik Polski published by the Polish People’s Republic Embassy in London with slander. Eventually, there was no trial, and the dispute ended in 1949 with an settlement. Instead the embassy in London had to pay a large sum as compensation.
The Rocky Road towards Professional Autonomy : The Estonian Journalists’ Organization in the Political Turmoil of the 20th Century
2017
This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association,…
