Eiropas Savienības un Ziemeļkorejas attiecības: Kima Čonina loma attiecību noteikšanā starp Eiropas Savienību un Ziemeļkoreju.
2015
Kopš 2001. gada Eiropas Savienība ir mēģinājusi uzturēt formālas attiecības ar Ziemeļkoreju, lai palīdzētu tās ekonomiskajai attīstībai un uzlabotu iekšzemes apstākļus. Tomēr attiecības nav izvērtušās pozitīvas, galvenokārt Ziemeļkorejas veiktās kodolprogrammas dēļ. Pavisam nesen Ziemeļkoreja piedzīvoja vadības maiņu līdz ar ģimenes diktatūru un neatbildēts ir jautājums, vai tas ir ietekmējis attiecības starp Eiropas Savienību un Ziemeļkoreju. Galvenais darba mērķis ir definēt attiecības starp Eiropas Savienību un Ziemeļkoreju divu dažādu periodu laikā (vadītāji Kims Čerins un Kims Čonins) un saprast vai tās ir mainījušās. Hipotēze apgalvo, ka vadības maiņas dēļ, attiecības starp ES un Ziem…
CO<SUB align="right">2 prices and portfolio management
2011
Since the launch of the European Union Emission Trading Scheme (EU ETS), the interest in the trade of EUAs is constantly increasing among academics and market participants. The objective of this paper is twofold: (a) a detailed description of this new market is provided for portfolio managers and (b) a comprehensive study of the implications of including Phase II EUAs in diversified portfolios is undertaken using as expected returns both historical and risk-adjusted returns. The results show that the opportunity set for investors increases when short positions in Phase II EUAs are taken.
On the thermal dynamic behaviour of the helium-cooled DEMO fusion reactor
2019
Abstract The EU-DEMO conceptual design is being conducted among research institutions and universities from 26 countries of European Union, Switzerland and Ukraine. Its mission is to realise electricity from nuclear fusion reaction by 2050. As DEMO has been conceived to deliver net electricity to the grid, the choice of the Breeding Blanket (BB) coolant plays a pivotal role in the reactor design having a strong influence on plant operation, safety and maintenance. In particular, due to the pulsed nature of the heat source, the Primary Heat Transfer System (PHTS) becomes a very important actor of the Balance of Plant (BoP) together with the Power Conversion System (PCS). Moreover, aiming to …
Advancements in the Helium-Cooled Pebble Bed Breeding Blanket for the EU DEMO: Holistic Design Approach and Lessons Learned
2019
The helium-cooled pebble bed (HCPB) blanket is one of the two concepts proposed as a driver blanket for the European Union Demonstration Fusion Power Reactor (EU DEMO). In contrast to past conceptual design studies, in the frame of the current Power Plant Physics and Technology of the EUROfusion Consortium, the ongoing EU DEMO preconceptual design activities have adopted a holistic and integrated (i.e., systems engineering) design approach. As a consequence of this new approach, many interfaces and requirements have been identified, some of them driving the design of the blankets. This paper shows the advancements in the HCPB breeding blanket and describes the lessons learned after implemen…
Formation and accumulation of radiation-induced defects and radiolysis products in modified lithium orthosilicate pebbles with additions of titanium …
2016
Abstract Lithium orthosilicate (Li4SiO4) pebbles with 2.5 wt.% excess of silicon dioxide (SiO2) are the European Union's designated reference tritium breeding ceramics for the Helium Cooled Pebble Bed (HCPB) Test Blanket Module (TBM). However, the latest irradiation experiments showed that the reference Li4SiO4 pebbles may crack and form fragments under operation conditions as expected in the HCPB TBM. Therefore, it has been suggested to change the chemical composition of the reference Li4SiO4 pebbles and to add titanium dioxide (TiO2), to obtain lithium metatitanate (Li2TiO3) as a second phase. The aim of this research was to investigate the formation and accumulation of radiation-induced …
Measurement of an excess ofB¯→D(*)τ−ν¯τdecays and implications for charged Higgs bosons
2013
The concept for this analysis is to a large degree based on earlier BABAR work and we acknowledge the guidance provided by M. Mazur. The authors consulted with theorists A. Datta, S. Westhoff, S. Fajfer, J. Kamenik, and I. Nisandzic on the calculations of the charged Higgs contributions to the decay rates. We are grateful for the extraordinary contributions of our PEP-II colleagues in achieving the excellent luminosity and machine conditions that have made this work possible. The success of this project also relied critically on the expertise and dedication of the computing organizations that support BABAR. The collaborating institutions wish to thank SLAC for its support and the kind hospi…
Low-diffusion Xe-He gas mixtures for rare-event detection: electroluminescence yield
2020
[EN] High pressure xenon Time Projection Chambers (TPC) based on secondary scintillation (electroluminescence) signal amplification are being proposed for rare event detection such as directional dark matter, double electron capture and double beta decay detection. The discrimination of the rare event through the topological signature of primary ionisation trails is a major asset for this type of TPC when compared to single liquid or double-phase TPCs, limited mainly by the high electron diffusion in pure xenon. Helium admixtures with xenon can be an attractive solution to reduce the electron diffu- sion significantly, improving the discrimination efficiency of these optical TPCs. We have m…
Enantioselective Synthesis of 4-Substituted Dihydrocoumarins through a Zinc Bis(hydroxyamide)-Catalyzed Conjugate Addition of Terminal Alkynes
2013
A new enantioselective catalyst for the conjugate addition of terminal alkynes has been developed. Terminal alkynes react with 3-alkoxycarbonylcoumarins in the presence of diethylzinc and bis(hydroxyamide) ligands to give chiral non-racemic dihydrocoumarins substituted with an alkynyl group on the C-4 position with good yields and enantiomeric excesses up to 95%.
Customising clinical studies for the new nursing generation
2021
Nursing education in the Nordic countries follows the European Union directive requirements, and clinical studies for nursing students in the Nordic countries have many similarities. Now a new generation of students with different needs and characteristics is entering the nursing profession. The faculty, teachers and nurses will face challenges in meeting this new generation’s needs. The primary aim of this discussion paper is to explore and compare the current clinical studies in the five Nordic countries. The secondary aim is to find means to address the future challenges with a focus on the new generation. The idea of Objective Structured Clinical Reflection creates the possibility to d…
Miksi työmarkkinoiden ja kielikoulutuksen tarpeet eivät kohtaa?
