A search for diffuse absorption bands in carbon-rich stars -- I. Barium and related stars
2003
The results of a search for interstellar and circumstellar absorption lines in high-resolution optical spectra of seven late-type stars are presented. All these stars are single-lined spectroscopic binaries with unseen companions, presumably white dwarfs. Some residual material indicative of recent mass transfer from an asymptotic giant branch (AGB) star might still be associated with the systems. Peculiar energy distribution and the sodium D 1 and D 2 lines give direct evidence about the material in the line of sight in some cases. Absorption features of simple carbon-bearing molecules (C 2 , CN) have been detected in most of the examined stars, confirming a carbon-rich nature of the corre…
Direct evidence of secondary recoiled nuclei from high energy protons
2008
The production of secondary recoiled particles from interactions between high energy protons and microelectronics devices was investigated. By using NAND Flash memories, we were able to directly obtain analog information on recoil characteristics. While our results qualitatively confirm the role of nuclear reactions, in particular of those with tungsten, a quantitative model based on Monte Carlo and device-level simulations cannot describe the observed results in terms of recoils from proton-W reactions. © 2006 IEEE.
Disentangling genuine from matter-induced CP violation in neutrino oscillations
2018
We prove that, in any flavor transition, neutrino oscillation CP violating asymmetries in matter have two disentangled components: (a) a CPT-odd T-invariant term, non-vanishing iff there are interactions with matter; (b) a T-odd CPT-invariant term, non-vanishing iff there is genuine CP violation. As function of the baseline, these two terms are distinct L-even and L-odd observables, respectively. In the experimental region of terrestrial accelerator neutrinos, we calculate their approximate expressions from which we prove that, at medium baselines, the CPT-odd component is small and nearly $\delta$-independent, so it can be subtracted from the experimental CP asymmetry as a theoretical back…
Very peculiar wind from BD+53°2790, the optical counterpart to 4U 2206+54
2008
BD+53 2790, an O9.5Vp star, is the optical counterpart to the HMXRB 4U 2206+54. This system was classified initially as a BeX, but observational evidence soon stressed the need to revise this classification. The permanent asymmetry in the H-alpha line profiles (in contrast with the cyclic variations shown by Be stars), the variations in the profile of this line in time scales of hours (while time scales from weeks to months are expected in Be stars), and the lack of correlation between IR observables and H-alpha line parameters, strongly suggest that, while BD+53 2790 contains a circunstellar disc, it is not like the one present in Be stars. Furthermore, there is evidence of overabundance o…
Lipid-lowering nutraceuticals in clinical practice: position paper from an International Lipid Expert Panel
2017
In recent years, there has been growing interest in the possible use of nutraceuticals to improve and optimize dyslipidemia control and therapy. Based on the data from available studies, nutraceuticals might help patients obtain theraputic lipid goals and reduce cardiovascular residual risk. Some nutraceuticals have essential lipid-lowering properties confirmed in studies; some might also have possible positive effects on nonlipid cardiovascular risk factors and have been shown to improve early markers of vascular health such as endothelial function and pulse wave velocity. However, the clinical evidence supporting the use of a single lipid-lowering nutraceutical or a combination of them is…
Visual Imagery, Mental Models, and Reasoning
2006
Abstract: The focus of this paper is the relation between Steven Kosslyn’s visual mental images and Johnson-Laird’s mental models. Knauff et al. presented empirical evidence and a challenging argument for the hypothesis that in fact “visual imagery impedes reasoning.” I argue that these results may look embarrassing for pictorialists, but closer inspection suggests that they are actually harmless. I argue that the presented evidence fails to show that imagery impedes reasoning. I present some objections to the explanation proposed by Knauff and Johnson-Laird by pointing out some terminological and conceptual problems. Afterwards, I sketch an alternative explanation, which is more pictoriali…
Доказательства и доказывание в гражданском процессе
2013
Civilprocesa teorijā pierādījumu un pierādīšanas jautājums ir viens no pamatinstitūtiem, kurš atrodas patstāvīgā attīstībā. Civiltiesisko strīdu daudzējādība un sabiedrības prasība ātri un kvalitatīvi izskatīt ierosināto civillietu tiesā, rada nepieciešamību attīstīt un pilnveidot civilprocesa pierādīšanas procesu un tā normatīvo regulējumu, kas radītu atbilstošu teorētisko bāzi un pilnveidotu esošo normatīvo regulējumu. Attīstoties dažādām tehnoloģijām un ienākot cilvēku ikdienā, kā arī komerciālajā apritē elektroniskajiem saziņas līdzekļiem, civilprocess nevar palikt konstants attiecībā uz pierādīšanas līdzekļu izmantošanas regulējumu un pierādījumu pieļaujamību un attiecināmību. Promocij…
Tadeusz Różewicz po niemiecku. Świadectwa lektury
2019
The title of the study covers both instances of Tadeusz Różewicz’s literary output, which are present within the circle of the German language (the art of translation) and the forms of the presences of the German literature and culture in the author’s own texts, metatexts, self-commentaries. Still, the poet’s dialogical word, as contextual and inter-textual networking (“knots in the net”) which creates an open space for the literary-cultural discourses (the following are present here, among others: Goethe, Holderlin, Celan, Nietzsche, Wittgenstein, Heidegger), becomes a superior value that permeates the character of the “textual world” active here. At the same time, a look at translation as…
The Rhetoric and Relevance of IS Research Paradigms: Conceptual Foundations and Empirical Evidence
2006
This paper discusses the relevance of IS research with respect to the rhetoric associated with the three major IS research paradigms in use - positivism, constructivism/interpretivism and critical research. The conceptual discussion is framed in terms of the following dimensions: ontological, epistemological and methodological assumptions, relationship between theory and practice, and the role of the researcher in the research process. Based on this discussion, we propose a conceptual model to study the relationship between the espoused philosophical assumptions of researchers and the degree of relevance of researchers’ knowledge claims. This conceptual model was evaluated with data obtaine…
The Union Societies’ Role in the Formation of a Parliamentary Culture of Debate
2016
Here the Oxford and Cambridge Unions are placed in the British tradition of debating societies. Haapala shows that the Unions were forerunners in the adoption of parliamentary debate and that they became models for other similar associations, thus taking a prominent role in the formation of a parliamentary culture of debate in Britain. The foundation of the Union Societies is discussed with comparisons to other contemporary and previously established debating societies, paying particular attention to membership requirements and rhetorical training. Finally, some first-hand accounts of the benefits of Union training for political careers will be provided.
