Statistical methodology to extract the mechanical properties, and the relative volumetric fraction, of the constituent phases of a composite from nanoindentation data without having to image the indentation marks.

L'organizzazione della porosità micro-ultramacro, pur avendo un generale carattere anisotropo (lunghi canali interconnesi da micro e macro pori) avviene secondo gerarchie diverse in funzione della tipologia della sospensione di partenza: concentrazione della fase solida e sue caratteristiche compositive, chimico-fisico-morfologiche e di solubilità, in quanto influiscono sulla stabilità della sospensione e sul processo di congelamento. Apatiti o altri calcio fosfati, diversamente ...

There is no other inorganic material that brings together such much intriguing features like porous silicon (PSi) for people working in the optical sensing field. Porous silicon was unexpectedly discovered in the late fifties when chemists attempted to electropolish silicon wafers with an electrolyte containing hydrofluoric acid to get better electrical contacts in the first integrated electronic circuit fabrications.1 The acid dissolution left a sponge-like nanocrystalline silicon structure on ...

The sheep (Ovis aries, 2n=54) is one of the most economically important livestock species, especially in the Mediterranean Countries. Although linkage and radiation hybrid maps are available, cytogenetic maps found in Web sites are still very poor and built, among other things, on old standard karyotypes. The recent construction of standard karyotypes in domestic bovids, including that of the sheep, based on both high resolution banded models, use of molecular markers and homologous chromosome ...

The growing diffusion of the Information and Communication Technology among any everyday assets and services is nowadays referred to as the "Pervasive ICT". The term "pervasive" well represents the trend that very soon hundreds of billions of microprocessors will be embedded within objects that do not even appear as ICT products and will govern in practice every aspect of our lives. This true revolution is progressively changing every business and the very way companies exist and compete. In any ...

Animals, especially those fed with natural pasture, represent real environmental sentinels. Indeed, being them fed with local plants and soil (taken together with grass) in place of breeding, give an idea of the degree of contamination of food and of the food chain. Indeed, many mutagenic substances present in the environment pass through animal products, to humans, laying the foundations for the onset of abnormal clinical picture (reproductive, hormonal and immune disorders). Check these ...

The negative effects of climate change are mostly observed in developing Countries, with particular emphasis on Asia. As in other parts of the world, this area is under a double threat: the first one, at a larger scale, is related to global warming as a result of increasing greenhouse gas emissions to which the Asian continent contributes significantly, while the second one is connected to climate change at the regional scale, influenced by the high aerosol - black carbon in the first place - ...

Mentre nel mondo ci sono ancora vaste aree di diffuso analfabetismo, nei paesi economicamente più sviluppati si parla di un nuovo tipo di alfabetizzazione (in Inglese literacy), più rispondente alla cosiddetta società della conoscenza: l'alfabetizzazione digitale (digital literacy). Chiarire il senso di questa locuzione non è un esercizio linguistico, ma è importante per comprendere e descrivere una nuova missione dei nostri sistemi educativi e formativi e conseguentemente le azioni ...

Per decifrare i problemi del presente e le possibilità di sviluppo economico e sociale del Mediterraneo è necessario fare i conti con la sua storia. E' forse questo uno dei nodi che oggi fornisce maggiore impulso agli studi su quest'area comune. Un interesse la cui evidenza emerge con forza alla luce della nuova stagione di par-tenariato inaugurata con la Dichiarazione di Barcellona (1995). Nel quadro delle attività scientifiche della rete euro-mediterranea Ramses 2, ispirata e coordinata ...
