Recent Developments In Eu Space Policy and Law

( Tanja Masson Zwaan ) 한국항공우주법학회 2010 한국항공우주정책·법학회지 Vol.25 No.2

This paper starts with a brief overview of the history of the European Space Agency and recalls some of its main features. Next, the gradual process of cooperation between ESA and the EU is outlined, leading to the creation of the Framework Agreement in 2004 and the adoption of the European Space Policy in 2007. The entry into force of the Lisbon Treaty in 2009 codified the space competence of the EU, and its implications are addressed. Lastly, some attention is paid to the issue of space security in Europe, through ESA`s new SSA programme adopted in 2008, and to the relevance of the EU Council initiative for a Code of Conduct for Outer Space Activities in 2008. The paper ends with some conclusions.

SIMMER extension for multigroup energy structure search using genetic algorithm with different fitness functions

Mattia Massone,Fabrizio Gabrielli,Andrei Rineiski 한국원자력학회 2017 Nuclear Engineering and Technology Vol.49 No.6

The multigroup transport theory is the basis for many neutronics modules. A significant point of the cross-section (XS) generation procedure is the choice of the energy groups' boundaries in the XS libraries, which must be carefully selected as an unsuitable energy meshing can easily lead to inaccurate results. This decision can require considerable effort and is particularly difficult for the common user, especially if not well-versed in reactor physics. This work investigates a genetic algorithm-based tool which selects an appropriate XS energy structure (ES) specific for the considered problem, to be used for the condensation of a fine multigroup library. The procedure is accelerated by results storage and fitness calculation speedup and can be easily parallelized. The extension is applied to the coupled code SIMMER and tested on the European Sustainable Nuclear Industrial Initiative (ESNII+) Advanced Sodium Technological Reactor for Industrial Demonstration (ASTRID)-like reactor system with different fitness functions. The results show that, when the libraries are condensed based on the ESs suggested by the algorithm, the code actually returns the correct multiplication factor, in both reference and voided conditions. The computational effort reduction obtained by using the condensed library rather than the fine one is assessed and is much higher than the time required for the ES search.

Current Issues & Prospects of International Space Law

( Tanja Masson Zwaan ) 한국항공우주정책·법학회 2010 한국항공우주정책·법학회지 Vol.25 No.1

This paper first gives a brief overview of the history of space law making in the international geopolitical context and recalls some of the main principles as elaborated in the framework of the United Nations. Next, several topics are discussed that will require the attention of space lawyers in the near future. They are the International Space Station, space debris, exploitation of space resources, space tourism, private property rights in space, and militarization and weaponization of space. The paper raises some questions in each of these areas that need to be addressed and concludes that the general legal framework for space activities under public international law as contained in the UN treaties is in place, and is sufficiently general and flexible to enable and encourage states to carry out space activities in an orderly manner. However, as demonstrated by the examples discussed in the paper, the time has come for the international community to agree on the further development of these general principles, starting perhaps with space debris, imminent `new` uses of space such as space tourism, or some of the `age-old` issues such as the weaponisation of outer space that will continue to require our attention and vigilance. Whether such rules can be in the form of non-binding guidelines, codes of conduct and the like, or should be embodied in solid legal instruments creating rights and obligations remains to be seen.

Elevated Lipoprotein(a) Levels and Atrial Fibrillation: A Systematic Review

Walter Masson,Leandro Barbagelata,Juan P Nogueira,Pablo Corral,Augusto Lavalle-Cobo,Francisco J. Romeo 한국지질동맥경화학회 2023 지질·동맥경화학회지 Vol.12 No.3

Objective: The role of lipoprotein(a) (Lp[a]) as a possibly causal risk factor for atherosclerotic cardiovascular disease has been well established. However, the clinical evidence regarding the association between Lp(a) levels and atrial fibrillation (AF) remains limited and inconsistent. This study aimed to analyze the association between elevated Lp(a) levels or single-nucleotide polymorphisms (SNPs) related to high levels of Lp(a) and AF. Methods: This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A literature search was performed to identify studies that evaluated the association between Lp(a) levels or SNPs related to high levels of Lp(a) and AF. Observational studies with a cross-sectional, case-control, or cohort design were included in this systematic review, without limitations according to language, country, or publication type. Results: Eleven observational studies including 1,246,817 patients were eligible for this systematic review. Two cross-sectional studies, 5 prospective/retrospective cohort studies, and 4 Mendelian randomization studies were analyzed. Two cross-sectional studies that compared Lp(a) levels between patients with and without AF showed conflicting results. Cohort studies that evaluated the incidence of AF according to Lp(a) levels showed different results: no association (3 studies), a positive association (1 study), and an inverse relationship (1 study). Finally, Mendelian randomization studies also showed heterogeneous results (positive association: 2 studies; inverse association: 1 study; no association: 1 study). Conclusion: Although there could be an association between Lp(a) levels and AF, the results of the studies published to date are contradictory and not yet definitive. Therefore, further research should clarify this issue.

Polyvinyl-alcohol fiber-reinforced concrete with coarse aggregate in beam elements

Leonardo M. Massone,Jaime Reveco,Alejandro Arenas,Fabian Rojas Techno-Press 2023 Advances in computational design Vol.8 No.2

The use of fibers has been commonly considered in engineered cementitious composites, but their behavior with coarse aggregate in concrete has not been studied significantly, which is needed to meet structural performance objectives for design, such as ductility. This research analyzes the behavior of fiber-reinforced concrete with coarse aggregate with 0.62%, 1.23%, and 2% PVA (Polyvinyl-alcohol) content, varying the maximum aggregate size. Tensile (direct and indirect) and compressive concrete tests were performed. The PVA fiber addition in coarse aggregate concrete increased the ductility in compression, especially for the fiber with a larger aspect ratio, with a minor impact on strength. In addition, the tensile tests showed that the PVA fiber increased the tensile strength of concrete with coarse aggregate and, more significantly, improved the ductility. A selected mixture was used to build short and slender reinforced concrete beams to assess the behavior of structural members. PVA fiber addition in short beams changed the failure mode from shear to flexure, increasing the deflection capacity. On the other hand, the slender beam tests revealed negligible impact with the use of PVA.

Cumulative damage in RC frame buildings - The 2017 Mexico earthquake case

Leonardo M. Massone,Diego Aceituno,Julian Carrillo Techno-Press 2023 Advances in computational design Vol.8 No.1

The Puebla-Morelos Earthquake (Mw 7.1) occurred in Mexico in 2017 causing 44 buildings to collapse in Mexico City. This work evaluates the non-linear response of a 6-story reinforced concrete (RC) frame prototype model with masonry infill walls on upper floors. The prototype model was designed using provisions prescribed before 1985 and was subjected to seismic excitations recorded during the earthquakes of 1985 and 2017 in different places in Mexico City. The building response was assessed through a damage index (DI) that considers low-cycle fatigue of the steel reinforcement in columns of the first floor, where the steel was modeled including buckling as was observed in cases after the 2017 earthquake. Isocurves were generated with 72 seismic records in Mexico City representing the level of iso-demand on the structure. These isocurves were compared with the location of 16 collapsed (first-floor column failure) building cases consistent with the prototype model. The isocurves for a value greater than 1 demarcate the location where fatigue failure was expected, which is consistent with the location of 2 of the 16 cases studied. However, a slight increase in axial load (5%) or decrease in column cross-section (5%) had a significant detrimental effect on the cumulated damage, increasing the intensity of the isocurves and achieving congruence with 9 of the 16 cases, and having the other 7 cases less than 2 km away. Including column special detailing (tight stirrup spacing and confined concrete) was the variable with the greatest impact to control the cumulated damage, which was consistent with the absence of severe damage in buildings built in the 70s and 80s.
