Investigación en la escuela
2008
Se analiza el desinterés de los estudiantes de Secundaria hacia las ciencias, en especial para las asignaturas de Física y Química y Tecnología. Una de las causas que motivan esta situación se debe a que el alumnado considera las asignaturas como aburrida. Por ello se plantea la conveniencia de una metodología basada en el empleo de una ciencia creativa, que utilice juegos y juguetes como material de aprendizaje. El estudio se apoya en una investigación que analiza los libros de texto y los resultados obtenidos de cuestionarios realizados a profesores y alumnos. Andalucía Madrid (Comunidad Autónoma).

High-Gradient RF laboratory at IFIC for medical applications
2018
General interest has been shown over the last years for compact and more affordable facilities for hadron-therapy. The High-Gradient (HG) know-how and technology for normal-conducting accelerating RF (Radio-Frequency) electron linac (linear accelerator) structures recently developed for projects such as CLIC (CERN), has raised the achievable accelerating gradient from 20-30 MV/m up to 100-120 MV/m. This gain has come through a better understanding of the high-power RF vacuum arcs or breakdowns (BD) phenomena, the development of quantitative HG RF design methods and refinements in fabrication techniques. This can allow for more compact linacs also for protons, which is potentially important …
IAEA Contribution to Nanosized Targeted Radiopharmaceuticals for Drug Delivery.
2022
The rapidly growing interest in the application of nanoscience in the future design of radiopharmaceuticals and the development of nanosized radiopharmaceuticals in the late 2000′s, resulted in the creation of a Coordinated Research Project (CRP) by the International Atomic Energy Agency (IAEA) in 2014. This CRP entitled ‘Nanosized delivery systems for radiopharmaceuticals’ involved a team of expert scientist from various member states. This team of scientists worked on a number of cutting-edge areas of nanoscience with a focus on developing well-defined, highly effective and site-specific delivery systems of radiopharmaceuticals. Specifically, focus areas of various teams of scientists com…
La persistenza della tradizione: considerazioni sulla tecnica costruttiva, sul dimensionamento e sul disegno progettuale dell’anfiteatro di Sabratha
2015
L’anfiteatro di Sabratha venne indagato nel 1924-26 da Renato Bartoccini, interessato in seguito da pochi interventi di scavo e restauro, è rimasto inedito. Le recenti indagini hanno permesso di redigere un nuovo rilievo e di avanzare un’ipotesi ricostruttiva. Terzo per grandezza tra gli anfiteatri noti nell’Africa Proconsolare, con una capacità stimata di circa 16.000 spettatori, è realizzato interamente in opera quadrata con conci di calcarenite locale e sembra essere stato progettato sulla base del cubito punico. Venne eretto probabilmente in età flavia all’interno di un più vasto progetto di ristrutturazione urbana e la sua enorme mole è giustificabile con il ruolo di Sabratha quale imp…
Earth Bricks with Halloysite Nanoclay: Research and Experimentation for the Sustainability of Materials
2021
The paper illustrates the experimentation activities on rammed earth and nanotechnologies conducted by the authors. The experimental research was carried out with the aim of improving the performance of rammed earth bricks with clay nanotubes, creating a ‘new material’ with reduced embodied energy and low CO2 emissions into the atmosphere. Specifically, the analysed performances are related to the compressive strength that expand their area of use as a building material.
Istituzioni del diritto privato - tomo secondo
2017
Questo testo è destinato a chi per la prima volta studia il diritto privato e a chi intende rivisitare nozioni e regole già note. La trattazione delle istituzioni, cioè dei fondamenti del diritto privato, viene sviluppata attraverso un percorso approfondito ed esteso, basato non soltanto sulle nozioni, ma anche sulla ricostruzione sistematica delle regole, attenta all’evoluzione dell’ordinamento in ragione della continua emersione di interessi e bisogni nuovi. In questa prospettiva, particolare attenzione è prestata al contributo dottrinale e giurisprudenziale che accompagna e rinnova la fisionomia e l’applicazione dei singoli istituti. Sulla base dell’esperienza didattica vissuta nelle aul…
Conversions and Resilient Materials
2018
Nowadays different and various forms of resilience draw our attention but, there is no doubt that, among all the inflated meanings of this term, we are greatly attracted by the one concerning the ability of the material itself to regenerate in a different present when it is widely employed both in sophisticated technologies and also in very simple methodologies to support Man in his research, his knowledge and his production in a world still to be planned far from the logic of the brutal beton. Today the anthropic world of what has already been built must be reconsidered in terms of redesign, systemic rewording, methods and results employed in the making (even in the case of new artifacts).…
Muscle‐tendon morphology and function following long‐term exposure to repeated and strenuous mechanical loading
2020
We mapped structural and functional characteristics of muscle‐tendon units in a population exposed to very long‐term routine overloading. Twenty‐eight military academy cadets (age: 21.00 ± 1.1 yrs; height: 176.1 ± 4.8 cm; mass: 73.8 ± 7.0 kg) exposed for over 24 months to repetitive overloading were profiled via ultrasonography with a senior subgroup of them (n = 11; age = 21.4 ± 1.0 yrs; height = 176.5 ± 4.8 cm; mass = 71.4 ± 6.6 kg) also tested while walking and marching on a treadmill. A group of eleven ethnicity‐ and aged‐matched civilians (age = 21.6 ± 0.7 yrs; height = 176.8 ± 4.3 cm; mass = 74.6 ± 5.6 kg) was also profiled and tested. Cadets and civilians exhibited similar morphology…
