© 2021, Springer Nature Switzerland AG.Digital cultural heritage resources are widely available on the web through the digital libraries of heritage institutions. To address the difficulties of discoverability in cultural heritage, the common practice is metadata aggregation, where centralized efforts like Europeana facilitate discoverability by collecting the resources’ metadata. We present the results of the linked data aggregation task conducted within the Europeana Common Culture project, which attempted an innovative approach to aggregation based on linked data made available by cultural heritage institutions. This task ran for one year with participation of twelve organizations, involving the three member roles of the Europeana network: data providers, intermediary aggregators, and the central aggregation hub, Europeana. We report on the challenges that were faced by data providers, the standards and specifications applied, and the resulting aggregated metadata.

The report presents the work carried out over seven months in 2015, during which our group has: - inventoried relevant semantic enrichment work in the Europeana Network in the past years. We have tried to do this in a way that we hope will facilitate identification and use of services relevant to the application that needs them. This includes general considerations on the diversity of the processes at hand and a focus on interoperability issues. - further developed criteria to select datasets for semantic enrichment and illustrate with a thorough analysis of selected examples - explored methodological issues for the evaluation of semantic enrichment services - performed a quantitative and qualitative evaluation of seven enrichment services on a same subset of the Europeana dataset, containing 17.300 records. This report, together with its two companion documents and a data space on the Europeana Assembla, presents all this. We have also included, as a conclusion, a number of lessons learned we think should be considered for the design and enhancement of enrichment services as well as for their evaluation.

La industria Automotriz es uno de los sectores de mercado más importantes a nivel mundial. En Ecuador, este ha ido desarrollándose considerablemente, y en la actualidad forma parte importante en las contribuciones de ingresos al sector gubernamental, además de generar empleo directo e indirecto. Debido a su crecimiento continuo, las operaciones a nivel financiero se pueden ver afectadas por la falta de instrumentos de control interno efectivos para garantizar la correcta gestión de sus operaciones. Es así como basados en estos aspectos, se genera el presente proyecto enfocado en determinar la razonabilidad de los saldos de las cuentas Ingresos – Cuentas por Cobrar – Cobranzas, mediante el examen de Auditoría de los riesgos inherentes, el fraude, realización de pruebas de control interno y aplicación de pruebas sustantivas, y así determinar los riesgos a los que se pueden enfrentar las industrias automotrices en el Ecuador, y recomendar acciones apropiadas para minimizar el riesgo de fraude y aumentar el control operacional.

Monográfico con el título: 'Pedagogía crítica del S. XXI'. Resumen basado en el de la publicación Se analizan las contribuciones de Paulo Freire a la Pedagogía Crítica sobre dos cuestiones diferentes, por un lado la 'Educación emancipadora: la influencia de Paulo Freire en la ciudadanía global' y por otro lado, 'La influencia de Paulo Freire en una educación para la libertad y la autonomía'. Ambas cuestiones se analizan no sólo como meras palabras, como frases vacías de significado, sino como palabras y frases que pueden transformar el mundo aportando una razón de ser en términos de política, ética y filosofía. A partir de este análisis se demostrará la existencia de una proposición ideológica inserta en estos enunciados que rechaza un todo coherente e importante en el ámbito de la verdadera Pedagogía Crítica, una perspectiva freireana política-ética-transformadora para la libertad y la autonomía.

The use of nuclear power through radiation for the destruction of microrganisms which cause food decay, and toxicosis, is specifically for peaceful purposes. Penicillium citrinum is a fungus which produce mycotoxins responsible for intoxication in humans and animals as a result of eating contaminated food. There is little informations on the resistance of P. citrinum to radiation. The objective of this research is to determine the lethal dose of gama radiation for these microrganisms. Seventy six suspensions containing approximately 100,000 spores/ml received a dose of radiation between 0.2 and 2.2 KGy (KiloGray), being one sample still alive re-irradiated with doses up to 3.0 KGy. The fungus were totally destroyed with a 2.2 KGy. Seventy six suspensions containing approximately 100,000 spores/ml received a dose of radiation between 0.2 and 2.2 KGy, being one sample still alive re-irradiated with doses up to 3.0 KGy. The fungus were totally destroyed with a 2.2 KGy dose. An increase in the resistance to lower dose levels of radiation was observed, in relation to the fungus which had not received irradiation. Conclusion: the Minimum Lethal Dose (MLD) of gamma irradiation, for P. citrinum is 2.2 KGy; the re-irradiation of the surviving fungus demonstrate that occur appearence of radio-resistant mutants O uso das radiações ionizantes na destruição de microrganismos responsáveis pela deterioração de alimentos ou causadores de infecções ou toxinfecções alimentares, constituiu-se aplicação da energia nuclear, para fins verdadeiramente pacíficos. Penicillium citrinum é um fungo produtor de micotoxinas, responsáveis por intoxicações em humanos e animais que se utilizam de alimentos contaminados. Há escassez de informações sobre a resistência do P. citrinum à irradiação gama; assim esta pesquisa objetivou determinar a dose letal por irradiação gama para esse microrganismo. Foram irradiadas 76 suspensões, contendo aproximadamente 100.000 esporos por mililitro, com doses entre 0,2 e 2,2 KGy (KiloGray), sendo os sobreviventes re-irradiados com doses até 3,0 KGy. O fungo foi totalmente destruído com dose de 2,2 KGy. P. citrinum descendentes dos sobreviventes de 2,0 KGy, quando re-irradiados também foram totalmente destruídos com dose de 2,2 KGy. Observou-se um aumento da resistência às doses mais baixas em relação ao fungo não irradiado

Steers and rabbits were used as experimental hosts for Anocenter nitens during scheduled infections, when ticks were recovered from naturally infected horses. Thus, the influence of the host species on the parasite was evaluated mainly considering parameters related to the engorgement period and pre molting of evolutive stages. It was also observed that almost 5% if the metanymphae and a few more than 1% of metalarvae fall off from the host to molt in the evironment, characterizing cycles in one or more hosts. The heteroxenous cycle is reported for the first time occuring in A. nitens.
