Seven Shades of Grey: A Follow-Up Study on the Molecular Basis of Coat Colour in Indicine Grey Cattle Using Genome-Wide SNP Data
2022
Shades of grey and brown are a dominant component in mammal coat colours, representing a fundamental trait involved in a great number of processes including cryptism, sexual selection and signalling. The genetic mechanisms of the grey colouration in mammals are very complex and controlled by hundreds of genes whose effects and interactions are still largely unclear. In this study, we adopted a robust multi-cohort Fst outlier approach based on pairwise contrasts between seven grey indicine cattle breeds and both taurine and indicine non-grey cattle breeds in order to find genomic regions potentially related to the grey colouration. On the basis of three main drawn settings, built in order to…
Comparison of different assembly and annotation tools on analysis of simulated viral metagenomic communities in the gut
2013
Abstract Background The main limitations in the analysis of viral metagenomes are perhaps the high genetic variability and the lack of information in extant databases. To address these issues, several bioinformatic tools have been specifically designed or adapted for metagenomics by improving read assembly and creating more sensitive methods for homology detection. This study compares the performance of different available assemblers and taxonomic annotation software using simulated viral-metagenomic data. Results We simulated two 454 viral metagenomes using genomes from NCBI's RefSeq database based on the list of actual viruses found in previously published metagenomes. Three different ass…
Review of wind tunnel modelling of flow and pollutant dispersion within and from naturally ventilated livestock buildings
2021
[EN] Ammonia emissions from naturally ventilated livestock buildings (NVLBs) pose a serious environmental problem. However, the mechanisms that control these emissions are still not fully understood. One promising method for understanding these mechanisms is physical modelling in wind tunnels. This paper reviews studies that have used this method to investigate flow or pollutant dispersion within or from NVLBs. The review indicates the importance of wind tunnels for understanding the flow and pollutant dispersion processes within and from NVLBs. However, most studies have investigated the flow, while only few studies have focused on pollutant dispersion. Furthermore, only few studies have s…
Critical Assessment of Feed-In Tariffs and Solar Photovoltaic Development in Vietnam
2022
Vietnam became the world’s third largest market for solar photovoltaic energy in 2020. Especially after the Vietnamese government issued feed-in tariffs for grid-connected solar photovoltaic systems, the installed capacity of solar photovoltaic applications exploded in 2019. From studies carried out in the relevant literature, it can be said that support policies are highly important for the initial development of the renewable energy industry in most countries. This is especially true in emerging countries such as Vietnam. This paper reviews the feed-in tariffs issued and deployed in different regions of Vietnam for grid-connected solar photovoltaic applications. Moreover, the paper takes …
Interaction and use of technologies in teaching and learning processes
2020
El nuevo escenario de la sociedad del conocimiento y los desafíos de aprendizaje que debe enfrentar la educación en este milenio han sido determinados por la transformación del mundo en las esferas económicas, políticas y culturales. En este artículo analizamos los procesos de interacción que se producen en los contextos educativos cuando las tecnologías son una oportunidad para lograr cambios profundos que contribuyan a mejorar los procesos de enseñanza aprendizaje desde nuevos planteamientos pedagógicos y curriculares. Todo ello conlleva una reorganización de los centros educativos, la formación y actualización del profesorado y la colaboración de las familias. Los docentes tienen ante sí…
Verde pensile estensivo ad alto valore ecologico in ambiente mediterraneo. Aspetti progettuali e funzionali
2013
Green areas are open spaces holding an unexpected kind of local biodiversity within the city, linked to species and habitats frequently found in human settlements. Green roofs can be an important means for environmental mitigation and, if designed according to the principles of restoration ecology, can improve the thermodynamic performance / hydraulic system and at the same time encouraging the development of urban biodiversity. With this work, we propose a methodology approach for green roofs in Mediterranean areas, that integrate aesthetic values with the functional traits of native species, in order to make green roofs “local tanks of biodiversity”.
La enseñanza monumentalista y utilitarista de las causas de la biodiversidad y de las estrategias para su conservación: un estudio sobre la transposi…
2015
Este trabajo estudia la presencia y complejidad en el tratamiento de las causas de la biodiversidad y de las razones para su conservación que realizan manuales escolares de la Educación Secundaria de España. Para ello, se determinó el ámbito conceptual y axiológico que define la comunidad de expertos, se examinó el tratamiento propuesto en el currículo español y se analizaron 50 manuales escolares (27 de la Educación Secundaria Obligatoria –ESO – y 30 del Bachillerato). Los resultados mostraron que el proceso de transposición didáctica vuelve monumentalista la enseñanza de la biodiversidad, ya que olvida las razones de su existencia, y se enriquece de connotaciones biologicistas y utilitari…
La scoperta, sistemazione e conservazione della grande Iscrizione di Gortina, nell'isola di Creta (1884-1921): la protezione delle testimonianze e le…
2013
La scoperta e la conservazione della Grande Iscrizione di Gortina a Creta, da parte degli studiosi italiani, fra la fine del XIX sec. e i primi decenni del XX sec., rappresentò un grande riconoscimento scientifico-culturale per la giovane nazione italiana. Nel passato, l’isola di Creta era stata legata alla Repubblica di Venezia e anche questo rapporto favorì l’invio a Creta del giovane epigrafista F. Halbherr, il quale fra notevoli peripezie rinvenne, assieme all’epigrafista tedesco E. Fabricius, la famosa l’iscrizione nell’antica città di Gortina. L’iscrizione, fra le più antiche e complete finora conosciute in tutta Europa, conteneva le norme sulla famiglia, l’eredità e in generale i dir…
How much geometry it takes to reconstruct a 2-manifold in R 3
2009
Known algorithms for reconstructing a 2-manifold from a point sample in R 3 are naturally based on decisions/predicates that take the geometry of the point sample into account. Facing the always present problem of round-off errors that easily compromise the exactness of those predicate decisions, an exact and robust implementation of these algorithms is far from being trivial and typically requires employment of advanced datatypes for exact arithmetic, as provided by libraries like CORE, LEDA, or GMP. In this article, we present a new reconstruction algorithm, one whose main novelties is to throw away geometry information early on in the reconstruction process and to mainly operate combina…
Asymmetric Comparison and Querying of Biological Networks
2011
Comparing and querying the protein-protein interaction (PPI) networks of different organisms is important to infer knowledge about conservation across species. Known methods that perform these tasks operate symmetrically, i.e., they do not assign a distinct role to the input PPI networks. However, in most cases, the input networks are indeed distinguishable on the basis of how the corresponding organism is biologically well characterized. In this paper a new idea is developed, that is, to exploit differences in the characterization of organisms at hand in order to devise methods for comparing their PPI networks. We use the PPI network (called Master) of the best characterized organism as a …
