VUV emission spectroscopy combined with H- density measurements in the ion source Prometheus I
2016
“Prometheus I” is a volume H− negative ion source, driven by a network of dipolar electron cyclotron resonance (ECR; 2.45 GHz) modules. The vacuum-ultraviolet (VUV) emission spectrum of low-temperature hydrogen plasmas may be related to molecular and atomic processes involved directly or indirectly in the production of negative ions. In this work, VUV spectroscopy has been performed in the above source, Prometheus I, both in the ECR zones and the bulk (far from ECR zones and surfaces) plasma. The acquired VUV spectra are correlated with the negative ion densities, as measured by means of laser photodetachment, and the possible mechanisms of negative ion production are considered. The well-e…
Noncovalent axial I∙∙∙Pt∙∙∙I interactions in platinum(II) complexes strengthen in the excited state
2021
Abstract Coordination compounds of platinum(II) participate in various noncovalent axial interactions involving metal center. Weakly bound axial ligands can be electrophilic or nucleophilic; however, interactions with nucleophiles are compromised by electron density clashing. Consequently, simultaneous axial interaction of platinum(II) with two nucleophilic ligands is almost unprecedented. Herein, we report structural and computational study of a platinum(II) complex possessing such intramolecular noncovalent I⋅⋅⋅Pt⋅⋅⋅I interactions. Structural analysis indicates that the two iodine atoms approach the platinum(II) center in a “side‐on” fashion and act as nucleophilic ligands. According to c…
Nordic Higher Education in Flux: System Evolution and Reform Trajectories
2019
AbstractThis chapter provides a brief description of how the four national systems included in this study—Denmark, Finland, Norway, and Sweden—are currently organised and structured. In doing so, it illuminates several specific features such as the types and sizes of the institutions, enrolment patterns, performance measures, and funding. In addition, the chapter gives a snapshot of how higher education systems have evolved historically by shedding light on policy dynamics from the late 1990s to 2013, the baseline period for the FINNUT comparative study, the research project that provides the basis for this edited volume. This is followed by a section describing the aim, methods, theoretica…
Węzłowe elementy relacji polsko-amerykańskich w świetle analizy ramowania
2021
Celem tego artykułu jest przedstawienie tematów poruszanych w odniesieniu do relacji polsko-amerykańskich podczas debaty parlamentarnej odbywającej się po exposé ministrów spraw zagranicznych oraz porównanie jej do treści zawartych w programach wyborczych polskich partii politycznych. Podstawową metodą badawczą użytą na potrzeby tego artykułu jest analiza zawartości oraz ramowanie (framing analysis). Objęto nimi exposé ministrów spraw zagranicznych oraz programy polskich partii politycznych w odniesieniu do relacji polsko-amerykańskich. Ma ona na celu porównanie i skonfrontowanie treści i tematów poruszanych w programach partii z treścią i tematami poruszanymi przez ministra spraw zagranicz…
Częstotliwość i ranga wizyt dyplomatycznych jako wyznacznik relacji polsko-amerykańskich na tle relacji brytyjsko-amerykańskich
2020
Celem niniejszej publikacji jest określenie stanu relacji polsko-amerykańskich na podstawie częstotliwości i rangi wizyt dyplomatycznych odbywanych między tymi państwami. Relacje te są przedstawiane w sferze zarówno politycznej, jak i naukowej jako fundamentalny element polskiej polityki zagranicznej. Jednocześnie brak niekwestionowanych wymiernych wskaźników pozwalających na ich obiektywną ewaluację. Relacje polsko-amerykańskie zostały w artykule porównane do strategicznego partnerstwa amerykańsko-brytyjskiego. Jako punkt odniesienia wykorzystano dane dotyczące wizyt dyplomatycznych brytyjsko-amerykańskich, co pozwala określić na tle porównawczym intensywność i rangę relacji polsko-ameryka…
On porn censorship and liberal ethics in the UK. Brief notes on the Audiovisual Media Services Regulations 2014
2015
This article deals with the highly criticised Audiovisual Media Services Regulations 2014, which provides that now the British Board of Film Classification (BBFC) regulations apply also to the videos-on-demand (and not only to DVDs).
.Single-Ion Magnetic Behaviour in an Iron(III) Porphyrin Complex: A Dichotomy Between High Spin and 5/2-3/2 Spin Admixture
2020
International audience; A mononuclear iron(III) porphyrin compound exhibiting unexpectedly slow magnetic relaxation, which is a characteristic of single-ion magnet behaviour, is reported. This behaviour originates from the close proximity (approximate to 550 cm(-1)) of the intermediate-spinS=3/2 excited states to the high-spinS=5/2 ground state. More quantitatively, although the ground state is mostlyS=5/2, a spin-admixture model evidences a sizable contribution (approximate to 15 %) ofS=3/2 to the ground state, which as a consequence experiences large and positive axial anisotropy (D=+19.2 cm(-1)). Frequency-domain EPR spectroscopy allowed them(S)= |+/- 1/2⟩->|+/- 3/2&Rig…
Federaliści i rozłam między klasycznością a modernością
2014
The article shows how the classical political thinking, based on civic virtues, and modernist thinking, based on individualism and self-interest, formed the basis of the U.S. Constitution. The Founding Fathers did not realize the full extent of the rift between classicism and modernity. When, as a result of intellectual discussions and practice of social life, this divide began to become more and more obvious, there has been a transition from the classical to the modernist paradigm in American politics. However, the dispute between classicism and modernity still continues and takes on new forms. On the one hand, contemporary political thinking is seen as a triumph of modernism, in which the…
A political not judicial process : impeachment in the U.S.
2019
Impeachment is inherently a political process in the United States. The political nature of impeachment makes political expediency a greater factor than any legal or even moral framework applicable. Therefore, the 2020 elections plays a significant role. nonPeerReviewed
Worldwide trends in blood pressure from 1975 to 2015: a pooled analysis of 1479 population-based measurement studies with 19.1 million participants
2017
Background Raised blood pressure is an important risk factor for cardiovascular diseases and chronic kidney disease. We estimated worldwide trends in mean systolic and mean diastolic blood pressure, and the prevalence of, and number of people with, raised blood pressure, defined as systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher. Methods For this analysis, we pooled national, subnational, or community population-based studies that had measured blood pressure in adults aged 18 years and older. We used a Bayesian hierarchical model to estimate trends from 1975 to 2015 in mean systolic and mean diastolic blood pressure, and the prevalence of rai…
