Defining “National Treasures” in the European Union. Is the Sky Really the Limit?

2019

The main objective of this article is to analyse the scope of EU Member States’ right to determine national treasures for the purpose of Directive 2014/60/EU on the return of cultural objects. While investigating the issue at the EU, human rights, and constitutional levels, the authors argue that the right to define what constitutes national treasures is not an absolute right. The definition of this particular category of cultural objects cannot be used to circumvent the rules on the free movement of goods and to hamper this freedom in an unjustifiable and arbitrary manner. On the human rights and constitutional levels, Member States’ right cannot interfere with the right to enjoy one’s pos…

Beyond the Cultural Turn: A Critical Perspective on Culture-Discourse within Public Relations

2017

International audience; In 1992, Sriramesh and White (1992) pointed to the importance of culture for public relations. Two decades later, public relations scholars had answered their call in force (e.g., Bardhan & Weaver, 2011; Carayol & Frame, 2012; Edwards & Hodges, 2011; Sriramesh & Vercic, 2012). Sriramesh and other PR scholars have criticized much previous public relations research for its focus on the work of Hofstede and cultural characteristics that are apparently common across countries (Sriramesh, 2009), rather than approaches which present culture as a social phenomenon on the level of the social group (Frame, 2012), or as a communication resource or tool-kit (Swidler, 1986). Sri…

Investigation of Wood Materials by Combined Application of X-ray and Neutron Imaging Techniques*

2014

Abstract Conservation of cultural heritage is extremely important not only from a cultural point of view, but also from a practical one. It is our duty to pass on to future generations the cultural heritage left to us by our ancestors. Wood is one of the most common materials used to generate works of art which are in a state of constant change and/or deterioration. In order to optimize the knowledge of artworks together with their conservation, it is necessary to use the most advanced scientific and technological tools. In the following paper, we will show the tomographic results which can be achieved by application of complementary techniques based on the combined use of X-ray and neutron…

Nachweis des di-2-cyanoisopropylperoxides bei der zersetzung von azoisobuttersäuredinitril in gegenwart von sauerstoff

1970

Das Di-2-cyanoisopropylperoxid entsteht in etwa 5-proz. Ausbeute bei der Zersetzung von Azoisobuttersaredinitril unter Sauerstoff in Isobutyronitril als Losungsmittel. Thermisch zerfallt das Peroxid est oberhalb von 120°C mit mesbarer Geschwindigkeit in einer Reaktion erster Ordnung. Die Aktivierungsenergie, in Cumol als Losungsmittel, wurde zu 37,9 kcal · mol−1 bestimmt. Werte fur die Zerfallskonstante bei 140°C sind in Cumol 0,057 h−1, in tert-Butylbenzol 0,073 h−1, in Chlorbenzol 0,18 h−1 und in o-Dichlorbenzol 0,23 h−1. Di-2-cyanoisopropylperoxide is formed when azobisisobutyronitrile is decomposed under oxygen in isobutyronitrile as a solvent. The yield amounts to ca. 5%. Thermal decom…

Specific recognition of fluoride anion using a metallamacrocycle incorporating a uranyl-salen unit

2008

The design and synthesis of a novel fluoride receptor that uses a salen-complexed Lewis acidic uranyl center as the sole binding site is reported here. This receptor binds fluoride anions in DMSO with a high affinity constant (K > 106 M-1) and exhibits a negligible affinity (K < 10 M-1) towards otherwise effective competitors, such as acetate, phosphate and cyanide anions.

Cultivation of algae with indigenous species – Potentials for regional biofuel production

2011

The massive need for sustainable energy has led to an increased interest in new energy resources, such as production of algae, for use as biofuel. There are advantages to using algae, for example, ...

Complementarity of reaction force and electron localization function analyses of asynchronicity in bond formation in diels-alder reactions

2014

We have computationally compared three Diels-Alder cycloadditions involving cyclopentadiene and substituted ethylenes; one of the reactions is synchronous, while the others are slightly or highly asynchronous. Synchronicity and weak asynchronicity are characterized by the reaction force constant κ(ξ) having just a single minimum in the transition region along the intrinsic reaction coordinate ξ, while for high asynchronicity κ(ξ) has a negative maximum with minima on both sides. The electron localization function (ELF) shows that the features of κ(ξ) can be directly related to the formation of the new C-C bonds between the diene and the dienophile. There is thus a striking complementarity b…

Effects of exercise training and montelukast in children with mild asthma

2008

Data from the general population suggest that habitual exercise decreases bronchial responsiveness, but the possible role of exercise in asthmatics is undefined. The leukotriene receptor antagonist montelukast decreases bronchial responsiveness and exercise-induced symptoms in asthmatic children. This randomized study in children with mild asthma evaluated the combined effects of aerobic training for 12 wk and montelukast or placebo on bronchial responsiveness (BHR) to methacholine, exercise-induced bronchoconstriction (EIB), inflammatory markers in exhaled breath condensate (EBC), and asthma exacerbations.Fifty children (mean age +/- SD: 10.2 +/- 2.4 yr) with mild stable asthma were random…

Multi-language translation and cross-cultural adaptation of the OARSI/OMERACT measure of intermittent and constant osteoarthritis pain (ICOAP).

2009

Summary Aim To conduct a multi-language translation and cross-cultural adaptation of the Intermittent and Constant OsteoArthritis Pain (ICOAP) questionnaire for hip and knee osteoarthritis (OA). Methods The questionnaires were translated and cross-culturally adapted in parallel, using a common protocol, into the following languages: Czech, Dutch, French (France), German, Italian, Norwegian, Spanish (Castillan), North and Central American Spanish, Swedish. The process was conducted following five steps: (1) – independent translation into the target language by two or three persons; (2) – consensus meeting to obtain a single preliminary translated version; (3) – backward translation by an ind…
