Experimental testing may be used to demonstrate the fire resistance of building construction elements. In order to allow comparing the results of tests made in different laboratories on various types of elements, the tests have to be performed under well-defined standardised conditions. Such standards define the heating and loading conditions, but also the performance criteria that have to be applied to measure the fire resistance duration. In Europe, the procedure that leads to the classification of building construction elements with regards to fire resistance involves a two level process. In the first stage, one or several tests are performed by a laboratory that must have accreditation according to ISO 17025, and one test report is issued for each test. Thereafter, a competent body will compile the necessary test reports and issue a classification report, the results of which can be used by the different stakeholders of the construction process, e.g. by authorities having jurisdiction. For the loadbearing performance, it appears that different logical combinations of the criteria are considered in the test standard and in the classification standard, leading to a inextricable situation. This situation has to be fixed in order to lead to a complete credible and applicable system. In order to provide scientific evidence about the consequences of adopting one or the other of both loadbearing definitions, the results of 46 tests performed in the fire resistance lab of the University of Liege in the recent years are analysed in this paper.

This report presents the results of numerical simulations on five tests conducted on reinforced concrete columns in fire. The data for the studied RC columns have been provided by the CERIB in the document “CEN-TC250-SC2-WG1-TG5_N0043_Annex_C_examples_Jesper_Jensen”. This study is part of the research project CEN-TC250-SC2-WG1-TG5 on the revision of EN1992-1-2, which focuses on the columns. The numerical software that is used for the simulations is the non-linear finite element software SAFIR, version 2013a0. [less ▲]

This article addresses the importance of cultural industries for the strengthening of the soft power of the rising powers and it seeks to understand how the cultural industries allow rising powers to shape the structures of their international environment. More specifically, studying the cases of People’s Republic of China and of the movie industry, my article focuses on the current evolution of the relationship between the Chinese authorities and the film industry, as well as on the development of the domestic film market. I further aim to draw up an inventory of China’s role within the global governance of cultural industries. Finally, I aim to highlight the global cultural competition that China faces, emphasizing the practices of the US administration and Hollywood. I argue that even if China is the current centre of gravity within the world economy, it still has a long way to go in order to shape the distribution of resources within the global governance of cultural industries and to play a crucial role in the international battle of cultural symbols.

RNAi therapeutics are promising therapeutic tools that have sparked the interest of many researchers. In an effort to provide a safe alternative to PEI, we have designed a series of new guanidinium and/or morpholino functionalized biocompatible and biodegradable polycarbonate vectors. The impact of different functions (morpholino-, guanidinium-, hydrophobic groups), of the architecture (linear homopolymer to dumbbell-shape) and of the molecular weight of these copolymers on their capacity to form polyplexes and to decrease the expression of two epigenetic regulators of gene expression, HDAC7 and HDAC5 was evaluated. The use of one of these polymers combining morpholine and guanidine functions at the ratio >1 and hydrophobic trimethylene carbonate groups showed a significant decrease of mRNA and protein level in HeLa cells, similar to PEI. These results highlight the potential of polycarbonate vectors for future in vivo application as an anti-cancer therapy. [less ▲]

The incidence of breast cancer, currently one woman on eight, also concerns patients who underwent augmentation surgery. Breast implants have already been the subject of numerous publications concerning the risk of inducing breast cancer or delaying the diagnosis, however, no significant causal relationship has been established. The purpose of this article is to assess the diagnostic and therapeutic consequences when breast cancer is identified in a patient with breast implants. [less ▲]

Delinquent and criminal behaviors are often the result of adverse conditions in the family and the neighborhood, or of affiliations with delinquent peers. However, case studies as well as large surveys have shown that even in adverse conditions, many children and adolescents do not engage in delinquency; they are “resilient.” In the explanation of criminal and antisocial behaviors, resilient individuals are those who have succeeded in overcoming at-risk circumstances. Resilience is also regarded as the process through which a person adjusts to at-risk situations in a successful manner. Promotive and protective factors stem from the community, family, school, peers, and individuals, and the configurations of these factors are important. In addition, protective factors are not universal. Risk factors and consequently, protective and resilience processes, may be different for children, adolescents, and adults, as well as for males and females. Finally, it is useful to distinguish primary resilience (i.e., as a preventive force in the onset of delinquency) from secondary resilience, which refers to a return to a crime-free life after a period of serious offending activity.

The quality of the oil of four safflower varieties, originating from Spain (Rancho), India (Sharda) and Morocco (Cartamar and Cartafri), which were cultivated at the experimental station in Oujda (a semi-arid region of eastern Morocco) was evaluated through analysis of their phenolic and carotenoid contents. The composition of the phenolic compounds of safflower oil has not yet been documented. Therefore, in this preliminary study, Thirty different phenolic compounds were identified, and significant differences between the oil varieties were observed (P < 0.05). In the seed oil from the Rancho and Sharda safflower varieties, the main phenolic compound was trans-chalcone, representing 13.45% and 11.8%, respectively, of the total phenolics, whereas in Cartamar and Cartafri oils, naringin accounted for 26.82% and 16.5%, respectively, of the total phenolics. The total carotenoid contents ranged from 1.13 mg/kg (Rancho) to 1.34 mg/kg (Cartamar and Cartafri).We observed that b-cryptoxanthin (0.31–0.37 mg/kg) and b-carotene (0.3–0.35 mg/kg) were the predominant carotenoids in all of the safflower oils that were studied.
