Fundamental and practical aspects concerning the characterization of smart textiles
2017
The research aims towards a novel methodology of ZnO impregnation onto polyamide supports, in order to attain a special inorganic-organic hybrid polymer material, with increased UV-barrier attributes and high hydrophobicity. The experimental approach employed ZnO micro particles powder. Solutions with different concentrations of ZnO powder dispersed in methanol are prepared as anti-UV finishing agent and applied onto polyamide fabric. The responsive behaviour of this complex polymer network to UV irradiation, the photo protective performance and its time stability, also the hydrophobic character are assessed by different characterization techniques. The proposed method has advantages, like:…
Potassium silver thiocyanate
2001
The structure of K[Ag(SCN)2] forms a three-dimensional network consisting of seven-coordinated K atoms and four-coordinated Ag atoms connected together by bridging thiocyanate groups.
Polyoxometalate-Based Molecular Materials.
1998
Molecule-based materials with active physical properties, in particular electrical, magnetic, and optical, are a focus of contemporary materials chemistry research. Certainly, one reason for this interest has been the realization that these materials can exhibit cooperative properties typically associated with the inorganic network solids, as for example metallic conduction or even superconductivity,1 ferromagnetism,2 and nonlinear optical properties.3 With respect to the electrical properties, many important achievements were obtained in the 1970s with the discovery of the first molecule-based metal in 1972,4 namely the π-electron donor-acceptor complex [TTF][TCNQ] (TTF ) tetrathiafulvalen…

La eclosión de la opinión del alumnado sobre la enseñanza de la Geografía. El geoforo iberoamericano en 2015
2015
Los datos que se aportan en esta síntesis anual nos indican que existe un crecimiento muy relevante no sólo en las visitas sino, sobre todo, en la participación del Geoforo Iberoamericano a través de las opiniones de alumnos y docentes. La didáctica de la Geografía se transforma en educación ciudadana por medio de las redes sociales, una aspiración que se ha gestado desde el año 2009. La colaboración de las personas de un lado y otro del Océano Atlántico nos permitirá definir con más rigor y precisión los desafíos de la formación docente en los próximos años.
La comunità educante di fronte alla pandemia: possibili strategie di intervento e nuovi scenari in un’ottica di rete
2022
Quando nel mese di marzo 2020, anche i servizi educativi 0-6 in Italia furono chiusi in base alle misure di sicurezza per pandemia da Covid 19, ci si ritrovò da un giorno all’altro e senza alcuna esperienza pregressa, ad organizzare delle forme di educazione a distanza e di sostegno alle famiglie e ai bambini. Nell’articolo, in particolare, descrivo come si è cercato di far fronte all’emergenza nei nidi e nelle scuole dell’infanzia gestiti dal Comune di Palermo e come l’esperienza del primo lock down abbia permesso di mettere a fuoco alcune strategie di intervento che si sono rivelate una risorsa potenzialmente trasferibile in situazioni di normalità. Sottolineo, inoltre, come la necessità …
Classification in point patterns on linear networks under clutter
2022
The problem of features detection under present of clutter in point process on linear networks establishes a methodological and computational challenge with multiple kind of applications as traffic accidents among other. Previous works related to the same topical but developed in more simpler geometries tackles the issue of the clutter removal through the distance of nearest-neighbour and show good results with high classification rates. We extend this procedure to the linear networks motivated by the classification of the traffic accidents on the road network of a city. Simulations demonstrate the performance of the method.
État actuel des réseaux de mesures éco-climatiques en Afrique centrale : les ambitions du projet de recherche international FORGREENE.
2016
This work presents an overview of spatio-temporal quality andspatial density of rainfall networks of Cameroon, Gabon, Congo, CAP and DRC, particularly in the recentperiod (1973-2014) through the GSOD international database. Faced with enormous gaps observed, theseresults will help to select metrological and analytical orientations in FORGREENE project (Tropical forestsgreeness and cloudiness in Central Africa: present conditions and future evolution). A comparison with rainfallsatellite estimates (RFE type) also indicates their great potential, provided they are based on in situ validations.

A gearbox model for processing large volumes of data by using pipeline systems encapsulated into virtual containers
2020
Software pipelines enable organizations to chain applications for adding value to contents (e.g., confidentially, reliability, and integrity) before either sharing them with partners or sending them to the cloud. However, the pipeline components add overhead when processing large volumes of data, which can become critical in real-world scenarios. This paper presents a gearbox model for processing large volumes of data by using pipeline systems encapsulated into virtual containers. In this model, the gears represent applications, whereas gearboxes represent software pipelines. This model was implemented as a collaborative system that automatically performs Gear up (by using parallel patterns…
