La vida cotidiana de los vecinos de Manila a través de sus testamentos e inventarios de bienes
2019
With the general objective indicated in its title, this work tries to highlight relevant aspects in the continuity of the Spanish domain in the Philippines, dependent on the maintenance of the Spanish capital. The inevitable selection of topics has lead the preferences of this work towards the residents collaboration to defend the city, the conversion of many of them into traders of exotic products and singular slaves owners, and their collaboration to an incredible miscegenation due to the ethnic variety. On the other hand, to follow the footsteps of the first generation of residents in Manila, at the end of the 16th century and during the 17th century, this work gives us some information …
Estudio sobre la presencia y el uso de las urnas Cruz del Negro en las necrópolis fenicias de Andalucía
2006
En este trabajo presentamos un análisis de las urnas Cruz del legro descubiertas en las necrópolis fenicias de Andalucía. Allí son escasas, lo que contrasta con el uso que se hace de esta forma en las necrópolis tartesias. Creemos que el continuo flujo comercial entre las dos poblaciones motivó un tráfico de mercancías que favoreció la adopción de elementos funerarios en las mismas.
Synthesis of a New C3-Symmetric Tripodal P4-Tetradentate Ligand and Its Application to the Formation of Chiral Metal Complexes
2010
A novel C3-symmetric tetradentate tripodal ligand with phosphorus as coordinating atoms has been synthesized in good yields. Its coordination ability through the four phosphorus atoms, three at the...
Correspondence between modified gravity and general relativity with scalar fields
2018
We describe a novel procedure to map the field equations of nonlinear Ricci-based metric-affine theories of gravity, coupled to scalar matter described by a given Lagrangian, into the field equations of General Relativity coupled to a different scalar field Lagrangian. Our analysis considers examples with a single and $N$ real scalar fields, described either by canonical Lagrangians or by generalized functions of the kinetic and potential terms. In particular, we consider several explicit examples involving $f(R)$ theories and the Eddington-inspired Born-Infeld gravity model, coupled to different scalar field Lagrangians. We show how the nonlinearities of the gravitational sector of these t…
Canonical equivalence of a generic 2-D dilaton gravity model and a free field
1997
We show that a canonical transformation converts, up to a boundary term, a generic 2-D dilaton gravity model into a free field theory with a Minkowskian target space.
Specialization and herding behavior of trading firms in a financial market
2008
Agent-based models of financial markets usually make assumptions about agent’s preferred stylized strategies. Empirical validations of these assumptions have not been performed so far on a full-market scale. Here we present a comprehensive study of the resulting strategies followed by the firms which are members of the Spanish Stock Exchange. We are able to show that they can be characterized by a resulting strategy and classified in three well- defined groups of firms. Firms of the first group have a change of inventory of the traded stock which is positively correlated with the synchronous stock return whereas firms of the second group show a negative correlation. Firms of the third group…
Formation of melanin-based wing patterns is influenced by condition and immune challenge in Pieris brassicae
2005
According to life-history theory, trade-offs emerge because organisms possess a limited amount of resources that they have to allocate between different bodily functions. Here, we tested whether there is a trade-off between melanin-based immune response and dark melanized wing patterning in the large white butterfly, Pieris brassicae L. (Lepidoptera: Pieridae), by activating the immune system of pupae and measuring the wing pigmentation of freshly emerged adults. In contrast to expectations, we did not find any negative associations between immune challenge and wing patterning. Furthermore, implanted and punctured male pupae tended to have larger and darker forewing tips as adults compared …
Safety and efficacy of novel dermal and epidermal microneedle delivery systems for rabies vaccination in healthy adults.
2010
International audience; In the present pilot study, intradermal ID delivery systems with a BD microneedle from 1 to 3mm in length, and epidermal delivery (BD skin abrader) through abraded skin surface relative to standard intramuscular injection were evaluated. Circulating neutralizing antibodies were measured against the rabies virus after the Vero cells rabies vaccine was administered at D0, D7, D21 and D49. This clinical evaluation in 66 healthy volunteers shows that ID delivery using BD microneedle technology of 1/4 the IM antigen dose is safe, efficient and reliable, resulting in a protective seroconversion rate. In contrast, the epidermal delivery route did not produce an immune respo…
Education in Ethiopia: Strengthening the Foundation for Sustainable Progress
2005
International audience; With the end of civil war in 1991, Ethiopia's government launched a New Education and Training Policy in 1994 which, by the early 2000s, had already produced remarkable results. The gross enrollment ratio rose from 20 to 62 percent in primary education between 1993-94 and 2001-02; and in secondary and higher education it climbed, respectively, from 8 to 12 percent and from 0.5 to 1.7 percent. Yet the government can hardly afford to rest on its laurels. Primary education is still not universal, and already there are concerns about plummeting educational quality and the growing pressures to expand post-primary education. Addressing these challenges will require more re…
Foreign and Security Policy
2015
In early 2014 the foreign and security policy discourse in the Baltic region was transformed as a resurgent and assertive Russia annexed Crimea and launched covert operations in eastern Ukraine.1 Observers were quick to point out that events in Ukraine eerily paralleled the 1940 occupation of the Baltic states. The traditional security concerns about Russian intentions in the region that the Baltic states had increasingly suppressed over the previous 20 years once again rushed to the surface. The post-existential era of Baltic foreign and security policy that had marked the decade that followed accession to the EU and NATO seemed to have come to an end.
