Decolonising European minds through Heritage
2019
By analysing three museums exhibition, this article investigates how the history of European colonialism is approached in an attempt to identify potential for decolonising European minds. The case studies consist of a temporary exhibition (2016–2017) concerning German colonialism at the Deutsches Historisches Museum in Berlin; the permanent exhibition of the House of European History in Brussels and the permanent exhibition of the Sagres Promontory (Portugal), a heritage site related to the conquest of the Americas. The analysis will focus on three aspects: 1) acknowledgement of connections between colonial histories and their contemporary influences in and for Europe; 2) the role of histor…
Génesis y resolución de conflictos relacionados con la instalación de mezquitas y oratorios: el caso del oratorio de Singuerlín (Santa Coloma de Gram…
2017
Durante los últimos años, se han sucedido, en diferentes territorios del Estado español, los conflictos relacionados con la instalación de mezquitas y oratorios destinados a la práctica del culto musulmán. Este artículo analiza uno de los conflictos más intensos, el desatado en 2004 ante el intento de apertura del oratorio del barrio de Singuerlín en Santa Coloma de Gramenet. Se estudia su raíz, su evolución y el papel que jugó la mediación intercultural en su gestión. A partir de las entrevistas en profundidad efectuadas con los actores implicados, varios años después, se analizan los elementos estructurales del conflicto y se plantea una reflexión acerca de la forma en la que se ha ido co…
The efficient bovine insulin presentation capacity of bone marrow-derived macrophages activated by granulocyte-macrophage colony-stimulating factor c…
1993
Bone marrow-derived macrophages (BMM phi) were shown before to function as antigen-presenting cells. We show here, that the antigen presentation capacity of BMM phi depends on the nature of the antigen and is differently regulated by the lymphokines interferon-gamma (IFN-gamma) and granulocyte/macrophage-colony-stimulating factor (GM-CSF). When bovine insulin (BI) was employed as antigen, only BMM phi treated with GM-CSF (GM-CSF-M phi) were efficient presenters, but when presentation of the antigens ovalbumin and conalbumin was tested, IFN-gamma-pulsed BMM phi (IFN-gamma-M phi) proved superior to GM-CSF-M phi. The lack of efficient BI presentation function of IFN-gamma-M phi was only obviou…
Comparative Antitumor Effect of Preventive versus Therapeutic Vaccines Employing B16 Melanoma Cells Genetically Modified to Express GM-CSF and B7.2 i…
2012
Cancer vaccines have always been a subject of gene therapy research. One of the most successful approaches has been working with genetically modified tumor cells. In this study, we describe our approach to achieving an immune response against a murine melanoma model, employing B16 tumor cells expressing GM-CSF and B7.2. Wild B16 cells were injected in C57BL6 mice to cause the tumor. Irradiated B16 cells transfected with GM-CSF, B7.2, or both, were processed as a preventive and therapeutic vaccination. Tumor volumes were measured and survival curves were obtained. Blood samples were taken from mice, and IgGs of each treatment group were also measured. The regulatory T cells (Treg) o…
Damage identification by a modified Ant Colony Optimization for not well spaced frequency systems
2011
Recently, it has been shown , that a damage detection strategy based on a proper functional calculated on the analytical signal of the structural dynamical response, consents to identify very low damage level. In this regard, they stressed the efficiency of Hilbert Transform to obtain the analytical response representation that shows more sensitivity for predicting damage with respect to the simple signal response. Then, a damage identification procedure based on the minimization of the difference between theoretical and measured data was proposed with satisfactory results. Unfortunately, this procedure, since the need of use of band pass filter around the natural frequency of the system, f…
Colonies
2015
The entry discusses David Ricardo's three main analytical arguments related to the colonial issue: i) colonies as a source of new fertile land and therefore as a viable solution to the problem of decreasing returns on domestic land; ii) colonies as possible outlet markets able to absorb domestic excess supply; and, finally, iii) the effects of trade restrictions between a colony and its mother country.
A Probabilistic Approach to the Count-To-Infinity Problem in Distance-Vector Routing Algorithms
2013
Count-to-infinity problem is characteristic for routing algorithms based on the distributed implementation of the classical Bellman-Ford algorithm. In this paper a probabilistic solution to this problem is proposed. It is argued that by the use of a Bloom Filter added to the routing message the routing loops will with high probability not form. An experimental analysis of this solution for use in Wireless Sensor Networks in practice is also included.
Ant Colony Search algorithm for optimal strategical planning of electrical distribution systems expansion
2005
Strategical planning is one of many research fields in the design of electrical distribution systems. The problem of strategical planning is a multiobjective combinatorial problem and the search space may often be quite large concerning to the options. The aim is to identify a strategy of expansion of a given distribution system in a given timeframe. For this problem, the search space is created beforehand by running a multiobjective optimisation algorithm for the optimal design of distribution networks for different load levels related to different years. The sets of Pareto-optimal solutions obtained for each load level at each year are equivalent in terms of the considered objectives, the…
Droit romain et Code Noir. Quelques réflexions a posteriori
2015
In Roman times, slavery is domestic, before conquests transformed its nature. Colonial slavery is an economic exploitation based on slave trade. How do the administrators apprehend the slave’s legal status ? Does the Code noir follow local rules or Roman precedents to supervise practice, according to some expected effects on the settlers’s property ? If Roman law serves as a matrix, is it as a simple recovery or as an indirect influence ? The spirit of antique solutions is present, but it is not essential for the legal definition of "Negros". The Roman law provides a conceptual tool to understand a posteriori the inner wheels of a specific status, at the turning point between property right…
Emergence of Aspergillus fumigatus azole resistance in azole-naïve patients with chronic obstructive pulmonary disease and their homes.
2017
Azole-resistant Aspergillus fumigatus (ARAF) has been reported in patients with chronic obstructive pulmonary disease (COPD) but has not been specifically assessed so far. Here, we evaluated ARAF prevalence in azole-naïve COPD patients and their homes, and assessed whether CYP51A mutations were similar in clinical and environmental reservoirs. Sixty respiratory samples from 41 COPD patients with acute exacerbation and environmental samples from 36 of these patient's homes were prospectively collected. A. fumigatus was detected in respiratory samples from 11 of 41 patients (27%) and in 15 of 36 domiciles (42%). Cyp51A sequencing and selection on itraconazole medium of clinical (n = 68) and e…
