A study of VUV emission and the extracted electron-ion ratio in hydrogen and deuterium plasmas of a filament-driven H−/D− ion source
2019
Vacuum ultraviolet (VUV) emission diagnostics for studying differences of electron impact processes in hydrogen and deuterium plasmas are presented. The method is applied to study a filament driven multicusp arc discharge negative ion source by comparing the VUV-emission intensities of different emission bands and extracted currents of H−/D− ions and electrons. It was found that the ratio of coextracted electrons to extracted ions is four times higher for deuterium than for hydrogen. No significant differences of the VUV-spectra or volumetric rates of ionization, excitation, production of high vibrational states, and dissociation were found between the plasmas of the two isotopes. The volum…

Masteroppgave grunnskolelærerutdanning trinn 1-7 NO502 - Universitetet i Agder 2019 The purpose of this thesis wasto investigate primary school teachers (grades 5-7) and their professional digital competence in the Norwegian subject. The research was based on the question: How do teachers arrange for a digital didactic in the Norwegian subject as a result of their professional digital competence?Through a phenomenologicalstudy, it wasan aim to try to understand twelve teachersstatements about what it means forteachersofNorwegian to have professional digital competence. The study also aimedto gain insight into how teachers create design for learning in digital environments using digital tool…
THE INVESTMENT POLITICS AND THE DIVERSIFICATION OF FINANCING RESOURCES IN ROMANIA
2011
A priority for Romania is to maintain an high investment rate, higher than the one of the EU member states, because these countries modernized their energetic, transport and public utility infrastructures, they developed their educational and the public health systems, they reduced the technological and informational differences, decades ago. Through the investment politics, Romania will continue to attract foreign investments, whose annual average was remarkable. For the financing of the investments, a diversification of the internal and external resources is necessary. The internal resources are based on the development of the saving instruments: the development of the market for transact…
The Origin of Non-thermal Fluctuations in Multiphase Flow in Porous Media
2021
Core flooding experiments to determine multiphase flow in properties of rock such as relative permeability can show significant fluctuations in terms of pressure, saturation, and electrical conductivity. That is typically not considered in the Darcy scale interpretation but treated as noise. However, in recent years, flow regimes that exhibit spatio-temporal variations in pore scale occupancy related to fluid phase pressure changes have been identified. They are associated with topological changes in the fluid configurations caused by pore-scale instabilities such as snap-off. The common understanding of Darcy-scale flow regimes is that pore-scale phenomena and their signature should have a…

The Diversification of Sicilian Farms: A Way to Sustainable Rural Development
2021
Rural areas still suffer from a lack of sustainable development, and the diversification of farms may be a step in the right direction. The paper provides a detailed picture of the diversification of Sicilian farms into tourism services. Specifically, we propose a simple indicator of localization intensity of agritourism farms and explore their spatial distribution at municipality level. Our study highlights that Sicilian farms rarely diversify into tourism services, despite being situated in attractive areas. That said, some significant spatial clusters of municipalities where agritourism farms are highly concentrated do emerge from the study.
Zróżnicowanie oferty instytucji kultury jako efekt dywersyfikacji źródeł ich finansowania
2015
Współcześnie można zaobserwować odejście od postrzegania kultury jedynie przez pryzmat wartości autotelicznych i dostrzeganie w niej walorów bardziej użytkowych. Wskutek tego procesu kulturę zaczęto postrzegać jako dźwignię rozwoju społecznego w bardzo zróżnicowanych wymiarach - począwszy od budowy kompetencji, poprzez tworzenie więzi lokalnych i wsparcia dla wykształcania się podmiotowej tożsamości, na kreowaniu spójności społecznej skończywszy. Jednocześnie instytucje kultury często borykają się z problemem ograniczonych zasobów finansowych koniecznych do pełnienia funkcji, do której zostały powołane. Celem artykułu jest przedstawienie możliwości finansowania instytucji kultury w kontekśc…
Latest reforms in Finnish doctoral education in light of recent European developments
2017
Doctoral education as a policy field is an important link between educational, research and innovation policies. It is gaining importance in European and national policy discussions. Doctoral education policies are increasingly formulated at the supranational level, even though the European Commission does not possess formal competence in terms of authority over the educational policies. Consequently, policy steering is mostly performed at the national level. In this article, we examine Finnish doctoral education from the steering perspective in a European context. We describe the development and steering of Finnish doctoral education, as well as the current doctoral education policies and …
Didactical resource purposes as an aspect of students’ decision making regarding resources used to learn mathematics
2019
International audience
Using schematic representation of resource systems to examine how first year engineering students use resources in their studies of mathematics
2018
International audience; Very little research has been done on how students use resources when studying mathematics. My project aim to examine this both quantitatively and qualitatively. The qualitative data collection includes hierarchical focus interviews and schematic representation of resource system, with the intent to impose as little terminology as possible on the students.
