Structure and phase transitions in ethylenediammonium dichloride and its salts with antimony trichloride

2000

During the mixing of ethylenediammonium dichloride and antimony trichloride except of reported earlier [NH3(CH2)2NH3]5(Sb2Cl11)2 · 4 H2O a new salt [NH3(CH2)2NH3](SbCl4)2 was obtained. The crystals are monoclinic at 295 K, space group C2/m, a = 13.829(3), b = 7.408(1), c = 7.588(2) Å; β = 103.18(3)°; V = 756.9(3) Å3; Z = 2; dc = 2.585, dm = 2.56(2) g · cm–3. The structure consists of anionic sublattice built of Sb2Cl82– units composed of two SbCl52– square pyramids connected by edge. The ethylenediammonium cations are located in anionic cavities. The cations are disordered. Each methylene carbon atom is split between two positions. The X‐ray diffraction, DSC, TGA and dilatometric methods we…

The Role of Perceived Social Support as a Contributor to the Successful Transition from Primary to Lower Secondary School

2019

Following approximately 1,800 Finnish children, this longitudinal study examined the associations between students’ perceived social support (teacher-student relationships, family support, and peer support), behavioral engagement, cynicism towards school, and academic achievement during the transition from primary to lower secondary school. After controlling for parental educational level and cynicism before the school transition, the results showed that the more students experienced pre-transition peer support, the less they reported post-transition cynicism. Furthermore, pre-transition peer support contributed to students’ increased academic achievement and behavioral engagement after the…

Finnish dairy farmers’ perceptions of justice in the transition to carbon-neutral farming

2022

Highlights • Finnish dairy farmers' perceptions of issues with carbon neutrality were examined. • Concerns include farming profitability, farmer blaming, and use of peatlands. • Public policy guidance is needed for carbon-neutral, sustainable agriculture. Environmental and political debate concerning the role of agriculture in sustainability has long been on the agenda. However, owing to climate change, an analysis of the transition to a low-carbon society must also be considered from the perspective of justice. Dairy farming, in particular, faces pressure in this context, when contemplating changing consumer behaviors and reduction in the carbon footprint of dairy products. Accordingly, ma…

THE PHYSICAL ORIGIN OF PROTEIN DYNAMICAL TRANSITION: A LIQUID-LIQUID TRANSITION IN HYDRATION WATER?

2015

In this thesis I study, by means of neutron scattering, calorimetry, and dielectric spectroscopy, the physical origin of protein dynamical transition (PDT) which is usually observed at ~230 K in protein hydrated powders and is deemed necessary for protein function. Measurements reported in this thesis have been performed on hydrated powders of Myoglobin. The combined use of different experimental techniques gives a coherent description of the PDT and reveals a connection with a liquid-liquid crossover occurring in the protein hydration water at about the same temperature. In order to deepen our understanding of this connection and to obtain a direct experimental evidence of the existence of…

Study Regarding the Effects of Demographic Transition on Labor Market and Public Pension System in Central and Eastern Europe

2020

Abstract Population and the quality of labor force are the “strengths” features’ that ensure socio-economic development of a country. The last decades can be characterized as a transitional period, in which countries of European Union and especially the countries of Central and Eastern Europe are facing a demographic decline. Reduced birth rate, ageing and migration are factors’ which create a lot of pressure, both on labor market and public pension systems, items correlated with the population structure. In this paper we have presented the demographic situation and the size of migration in five countries of Central and Eastern Europe. The direct linkage between population structure, labor …

Measuring nuclear reaction cross sections to extract information on neutrinoless double beta decay

2017

Neutrinoless double beta decay (0v\b{eta}\b{eta}) is considered the best potential resource to access the absolute neutrino mass scale. Moreover, if observed, it will signal that neutrinos are their own anti-particles (Majorana particles). Presently, this physics case is one of the most important research "beyond Standard Model" and might guide the way towards a Grand Unified Theory of fundamental interactions. Since the 0v\b{eta}\b{eta} decay process involves nuclei, its analysis necessarily implies nuclear structure issues. In the NURE project, supported by a Starting Grant of the European Research Council (ERC), nuclear reactions of double charge-exchange (DCE) are used as a tool to extr…
