Analyses of the OSU-MASLWR Experimental Test Facility
2012
Today, considering the sustainability of the nuclear technology in the energy mix policy of developing and developed countries, the international community starts the development of new advanced reactor designs. In this framework, Oregon State University (OSU) has constructed, a system level test facility to examine natural circulation phenomena of importance to multi-application small light water reactor (MASLWR) design, a small modular pressurized water reactor (PWR), relying on natural circulation during both steady-state and transient operation. The target of this paper is to give a review of the main characteristics of the experimental facility, to analyse the main phenomena characteri…
Interaction between N-terminal domain of H4 and DNA is regulated by the acetylation degree.
1998
Abstract To study whether the acetylation of one or more of the four acetylatable lysines of histone H4 affects its binding to DNA, we have designed a protection experiment with a model system consisting in phage lambda DNA as substrate, Stu I as restriction endonuclease and histone H4 with different degrees of acetylation as the protective agent. It can be deduced from the experimental data that the protection afforded by the histone is not dependent on the number of positive charges lost by acetylation. Thus, non-acetylated H4 and mono-acetylated H4 cause similar protection, while di-acetylation of the histone seems to be the crucial step in significantly weakening the interaction between…
Gcn5p is involved in the acetylation of histone H3 in nucleosomes.
1997
Abstract Enzymatic extracts from a gcn5 mutant and wild-type strains of Saccharomyces cerevisiae were chromatographically fractionated and the histone acetyltransferase activities compared. When free histones were used as substrate, extracts from wild-type cells showed two peaks of activity on histone H3 but extracts from gcn5 mutant cells showed only one. With nucleosomes as substrate, the histone acetyltransferase activities present in extracts from the gcn5 mutant strain were not able to modify H3 whereas wild-type cell extracts acetylated intensely this histone. The activity that acetylated nucleosome-bound H3 behaved as a 170-kDa complex. We suggest that Gcn5p represents a catalytic su…
Sample details on OSL data for aeolian sediments in north-eastern part of European Sand Belt
2019
A compilation of previously published and unpublished absolute age (OSL and TL) determinations of aeolian sediments from the north-eastern part of European Sand Belt. Contains age, error, sampling depth, location etc. and a reference to data source. Coordinates of sampling locations for contemporary publications are taken from field observations (GPS), but older ones - published schematic maps. Data set is created according to schema of DATED-1 database (https://doi.org/10.1594/PANGAEA.848117).
Ethical Demands and Responsibilities in Online Publishing: The Finnish Experience
2014
Rapid advancement of online communication and publishing poses new challenges to media policy-makers and regulators for both statutory regulation and self-regulation. For journalists, ‘the Internet shapes and redefines a number of moral and ethical issues … when operating online or making use of online resources’ (Deuze and Yeshua, 2001: 276).
Aristotle and Pedagogical Ethics
2020
The teacher’s pedagogical ethics refers to the Kantian maxims that a teacher is obliged to follow. One could provide a list of the most crucial maxims that a teacher must absolutely not violate. We surely need these Kantian maxims in the teachers’ pedagogical ethics, although they tell us very little about the properties that good and moral teachers should possess. In teacher education we must of course elaborate on the ethical code of the teacher (maxims), but we must also consider the properties of a morally good teacher. A good source in endeavouring to find these properties is the book Aristotle wrote over 2,000 years ago, Nicomachean Ethics. According to Aristotle, a virtuous citizen m…
Instytucjonalny wymiar ochrony granic zewnętrznych Unii Europejskiej w kontekście bezpieczeństwa państw członkowskich
2018
Celem artykułu jest analiza problemu funkcjonowania instytucji zapewniających ochronę zewnętrznych granic Unii Europejskiej pod kątem zagwarantowania bezpieczeństwa jej państwom w kontekście współczesnych wyzwań. Do chwili, kiedy zaistniał kryzys migracyjny istniało bowiem przekonanie, że Unia Europejska stworzyła instytucjonalne warunki dla skutecznego zapewnienia bezpieczeństwa swoich granic. UE to przestrzeń, w obrębie której realizowana jest swoboda przemieszczania się obywateli, wyrażona poprzez swobodę podróżowania, podejmowania pracy, studiowania czy zamieszkiwania w wybranym kraju Unii. Realizacja tej swobody nastąpiła w wyniku zniesienia kontroli na wewnętrznych granicach UE. Jedna…
Bezpieczeństwo granic Unii Europejskiej w kontekście kryzysu migracyjnego 2015/2016
2016
The European Union is a space within which the freedom of movement of citizens, expressed through freedom to travel. work, study or live in a chosen EU country, is realized. The implementation of this freedom was a result of the abolition of Controls at internal borders of the Union. However. for a Member of the EU, the price of this freedom is the necessity to ensure national security, which makes the protection of external borders a special task. The European Union, through the Schengen Agreement, created institutions for the protection of external borders in terms of ensuring the national security of Member States, The current migration crisis is a serious verification of the effectivene…
Instytucja granic zewnętrznych Unii Europejskiej a zapewnienie bezpieczeństwa państw członkowskich w warunkach współczesnego kryzysu migracyjnego
2017
Unia Europejska to przestrzeń w obrębie której realizowana jest swoboda przemieszczania się obywateli. Realizacja tej swobody nastąpiła w wyniku zniesienia kontroli na wewnętrznych granicach Unii. Jednak dla państwa unijnego ceną tej wolności jest zapewnienie bezpieczeństwa narodowego co czyni szczególnym ochronę granic zewnętrznych. Unia Europejska, głównie poprzez Układ z Schengen stworzyła instytucje dla ochrony granic zewnętrznych pod kątem zapewnienia bezpieczeństwa narodowego państw członkowskich i ich obywateli. Obecny kryzys migracyjny stanowi poważną weryfikację dla oceny skuteczności działania tych instytucji. Celem niniejszego artykułu jest analiza problemu funkcjonowania zewnętr…
Pattern Recognition Scheme for Large-Scale Cloud Detection over Landmarks
2020
Landmark recognition and matching is a critical step in many Image Navigation and Registration (INR) models for geostationary satellite services, as well as to maintain the geometric quality assessment (GQA) in the instrument data processing chain of Earth observation satellites. Matching the landmark accurately is of paramount relevance, and the process can be strongly impacted by the cloud contamination of a given landmark. This paper introduces a complete pattern recognition methodology able to detect the presence of clouds over landmarks using Meteosat Second Generation (MSG) data. The methodology is based on the ensemble combination of dedicated support vector machines (SVMs) dependent…
