La reproducción asistida y la filiación. Especial referencia al caso de las parejas de mujeres homosexuales
2018
This paper analyses, in general, the evolution that has had the art. 7.3 LTRHA since its introduction by the Act 3/2007, 15 march. In that way, it shows which has been the legislator´s solution about the use of assisted reproduction tecniques by homosexual women couples. Likewise, it studies which resolutions on the matter have been more relevant in the last years. All this, to set out the legislator´s failure and the need to reformulate the filiation regime in face of the challenge that assisted reproduction implies.
Potentials for critical raw materials recovery from Mediterranean saltworks bitterns
2022
Minerals extraction from seawater brines is currently regarded as the most practical approach to reduce European dependency from the import of many Critical Raw Materials. The technical feasibility of such approach has been widely demonstrated in several different research and development projects but the economic sustainability has always been found to depend on the local demand for sodium chloride, which is always the most abundant product of the extraction. Starting from this crucial node, the SEArcularMINE project has investigated the possibility to use the residual brines originated by sea-salt extraction in traditional saltworks, regarded as an already well-established marketplace. Th…
Volcanic CO2 mapping and flux measurements at Campi Flegrei by Tunable Diode Laser absorption Spectroscopy
2014
Near-infrared room-temperature Tunable Diode Lasers (TDL) have recently found increased usage in atmospheric chemistry and air monitoring research, but applications in Volcanology are still limited to a few examples. Here, we explored the potentiality of a commercial infrared laser unit (GasFinder 2.0 from Boreal Laser Ltd) to measurement of volcanic CO2 flux emissions. Our field tests were conducted at Campi Flegrei (near Pozzuoli, Southern Italy), where the GasFinder was used (during three campaigns in October 2012, January 2013 and May 2013) to repeatedly measure the path-integrated concentrations of CO2 along cross-sections of the atmospheric plumes of the two main fumarolic fields in t…
TAKING INSPIRATION FROM NATURE: RULES AND PROCEDURES FOR A GOOD BUILDING PRACTICE
2016
Sin dai tempi antichi si sono sfruttati gli alberi ed altri elementi vegetali per scopi costruttivi: la natura, in generale, è stata di ispirazione e ha insegnato una serie di regole, a lungo imitate ed applicate. Alcune delle numerose specie arboree hanno rappresentato, infatti, degli esempi per le costruzioni primitive e, successivamente, per gli stili architettonici classici: possiamo annoverare i primi rifugi estemporanei ed ispirati a criteri di urgenza e praticità, o anche ben più ragionati edifici, fatti di elementi vegetali assemblati fra di loro. Questi manufatti architettonici richiamavano la natura nel suo fiorente sviluppo e nel sapiente e preciso equilibrio. L’architettura clas…
Prevenzione e riabilitazione sismica degli elementi non-strutturali. Vulnerabilità e misure di prevenzione per il patrimonio architettonico del XX se…
2010
Il contenimento dei danni agli elementi non-strutturali, perseguito con un’opportuna cultura della prevenzione già in fase progettuale, pur impegnando risorse in fase di realizzazione o di riabilitazione e di retrofitting, si traduce in un risparmio post-sisma. Inoltre, la funzionalità e l’operatività degli edifici si esplica attraverso il corretto funzionamento degli impianti e la stabilità di arredi, equipaggiamenti, finiture ed opere accessorie. Le tecniche di prevenzione e riabilitazione non possono prescindere dalla qualità realizzativa degli elementi costruttivi quale imprescindibile condizione di sicurezza ed affidabilità, e tradotta come idoneo impiego e consapevole scelta dei mater…
Influence of biochar on the physical, chemical and retention properties of an amended sandy soil
2017
Soil porosity plays an important role in soil-water retention and water availability to crops, potentially affecting both agricultural practices and environmental sustainability. The pore structure controls fluid flow and transport through the soil, as well as the relationship between the properties of individual minerals and plants. Moreover, the anthropogenic pressure on soil properties has produced numerous sites with extensive desertification process close to residential areas. Biochar (biologically derived charcoal) is produced by pyrolysis of biomasses under low oxygen conditions, and it can be applied for recycling organic waste in soils and increase soil fertility, improving soil st…
COSTRUIRE L’AZZARDO. IL CORNICIONE NELL’ARCHITETTURA STORICA, FRA REGOLA E SPERIMENTAZIONE
2018
The book explores the historical and constructive aspects of the cornices that, from elements of protection, they can also become elements of degradation and instability due to their form. The structure of the text of this volume consists of three main parts, presenting some technical aspects and issues of uncommon attention. The first part analyzes a discussion about the formal and material values of the cornice; in fact, it presents complex characters and summarizes the problems deriving from formal and constructive requirements of the building envelope, due to the double value of ornamentation (crowning of the building) and functional component (removal system of meteoric water from the …
Fingerprint Traits and RSA Algorithm Fusion Technique
2012
The present work deals with modern computing systems security issues, focusing on biometric based asymmetric keys generation process. Conventional PKI systems are based on private/public keys generated through RSA or similar algorithms. The present solution embeds biometric information on the private/public keys generation process. In addition the corresponding private key depends on physical or behavioural biometric features and it can be generated when it is needed. Starting from fingerprint acquisition, the biometric identifier is extracted, cyphered, and stored in tamper-resistant smart card to overcome the security problems of centralized databases. Biometric information is then used f…
Scienza e tecnica. Heidegger, Heisenberg e il Weltbild della scienza contemporanea
2021
Heidegger's will to go beyond the anthropological-instrumental conception of technique does not result in a mythopoetics of technique as a fatal destiny to resign oneself to, nor in the suggestion of becoming accomplices in an uncontrolled advance of the technique itself. In the dialogue with Heisenberg on the occasion of the cycle of lectures on The arts in the age of technique, the trait of technique emerges understood from the point of view of "historical occurrence" in its essential distinction from "historiographic observation", a trait that appears decisive for the reformulation of the Seinsgeschichte, and that while leaving unresolved the controversial question of the role of the hum…
Measuring lung function in asthmatic children: A spirometry and forced oscillation technique (FOT) comparison
2016
Background: Spirometry is the most common pulmonary function test used in asthma diagnosing. However, it requires good patient co-operation. FOT has gained increasing attention for the measurement of pulmonary function in children because it is performed at steady state breathing. Aim: To compare spirometry and FOT in order to discriminate severity of asthma according to GINA. Methods: Spirometry and FOT were performed in 176 out-patient asthmatic children (5-16 year), 100 (57%) with naive Persistent Asthma (PA) and 76 (43%) with Intermittent Asthma (IA), consecutively enrolled at the IBIM pediatric clinic. Two principal component analyses (PCA) were performed, the first (PCA1) based on FEV…
