La buona fede in senso oggettivo
2015
La monografia rappresenta il tentativo di realizzare una trattazione unitaria delle principali forme in Europa di concretizzazione della clausola generale di buona fede, cercando di compiere una riconduzione ad unità finalizzata ad una razionalizzazione di ordine concettuale. Lo studio investiga tutte le più significative funzioni della buona fede oggettiva, muovendo da quelle tradizionali fino ad approdare a quelle più recenti, portate alla ribalta dal diritto privato europeo di origine sia legislativa, sia giurisprudenziale sia dottrinale. Alla luce del significato normativo, concettuale e valoriale unitario che si è ritenuto di individuare, lo studio evidenzia le forme di impiego della b…
Further evidence for CCN aerosol concentrations determining the height of warm rain and ice initiation in convective clouds over the Amazon basin
2017
We have investigated how aerosols affect the height above cloud base of rain and ice hydrometeor initiation and the subsequent vertical evolution of cloud droplet size and number concentrations in growing convective cumulus. For this purpose we used in situ data of hydrometeor size distributions measured with instruments mounted on HALO aircraft during the ACRIDICON–CHUVA campaign over the Amazon during September 2014. The results show that the height of rain initiation by collision and coalescence processes (Dr, in units of meters above cloud base) is linearly correlated with the number concentration of droplets (Nd in cm−3) nucleated at cloud base (Dr ≈ 5 ⋅ Nd). Additional cloud processes…
Sensitivities of Amazonian clouds to aerosols and updraft speed
2017
Abstract. The effects of aerosol particles and updraft speed on warm-phase cloud microphysical properties are studied in the Amazon region as part of the ACRIDICON-CHUVA experiment. Here we expand the sensitivity analysis usually found in the literature by concomitantly considering cloud evolution, putting the sensitivity quantifications into perspective in relation to in-cloud processing, and by considering the effects on droplet size distribution (DSD) shape. Our in situ aircraft measurements over the Amazon Basin cover a wide range of particle concentration and thermodynamic conditions, from the pristine regions over coastal and forested areas to the southern Amazon, which is highly poll…
The ACRIDICON-CHUVA campaign: Studying tropical deep convective clouds and precipitation over Amazonia using the new German research aircraft HALO
2016
Abstract Between 1 September and 4 October 2014, a combined airborne and ground-based measurement campaign was conducted to study tropical deep convective clouds over the Brazilian Amazon rain forest. The new German research aircraft, High Altitude and Long Range Research Aircraft (HALO), a modified Gulfstream G550, and extensive ground-based instrumentation were deployed in and near Manaus (State of Amazonas). The campaign was part of the German–Brazilian Aerosol, Cloud, Precipitation, and Radiation Interactions and Dynamics of Convective Cloud Systems–Cloud Processes of the Main Precipitation Systems in Brazil: A Contribution to Cloud Resolving Modeling and to the GPM (Global Precipitatio…
Observed and Simulated Variability of Droplet Spectral Dispersion in Convective Clouds Over the Amazon
2021
In this study, the variability of the spectral dispersion of droplet size distributions (DSDs) in convective clouds is investigated. Analyses are based on aircraft measurements of growing cumuli near the Amazon basin, and on numerical simulations of an idealized ice‐free cumulus. In cleaner clouds, the relative dispersion ϵ, defined as the ratio of the standard deviation to the mean value of the droplet diameter, is negatively correlated with the ratio of the cloud water content (qc) to the adiabatic liquid water content (qa), while no strong correlation between ϵ and qc/qa is seen in polluted clouds. Bin microphysics numerical simulations suggest that these contrasting behaviors are associ…
Durum wheat yield uncertainty under different tillage management practices and climatic conditions
2019
Abstract In the field of conservative agriculture, no-till (NT) management has been receiving increasing interest, with 45 million ha of land under no-till management in 1999 to 155 million ha in 2014. Up until now, no-till has only been observed to perform better under rainfed conditions, especially in dry climates mainly because the reduced tillage system retains more soil moisture. However, the adoption of alternative agricultural practices (NT) can be improved only if uncertain and consequent assumption of risk is well known and accepted. For these reasons, the aim of this research is (i) to define durum wheat suitability under NT soil management in terms of yield success probability an…
Introduzione alla lettura di Paolo Di Paolo
2014
In Scrivere è un gioco di prestigio (2010) Paolo Di Paolo ribadisce quanto sia fondamentale il dialogo reale o ideale con altri scrittori muovendo dall’assunto che la “conversazione sia una forma particolare di ermeneutica della sollecitazione, nella quale fai delle domande agli altri perchè le stai facendo a te stesso” e, ancora, rileva come si senta particolarmente attratto da quegli “scrittori che hanno fatto del rapporto con il vissuto la loro chiave di indagine dell’esperienza umana”. Ripercorrendo le fasi salienti del suo percorso narrativo, da Come un’isola. Viaggio con Lalla Romano (2006) a Raccontami la notte in cui sono nato (2008) a Dove eravate tutti (2011) sino a Mandami tanta …
Blogging as a research and educational tool: a three years experience
2008
Abstract Blogging can be also used to share knowledge in research and education. We have been using many blogs with the following purposes. One goal has been to raise awareness about research methods in the information technology field by supporting information exchange, collaboration, and cooperation between researchers. We have been using a common blog for 3 years to share inter- and intra disciplinary knowledge among us. We have also collected stories and interviewed colleagues and friends. An other goal is the use of blogs during our teaching experience as an instrument to support the exchange of knowledge with students. A comparison of the use of blogging is presented with positive and…
Sublimazione e repressione: la crisi delle scienze europee e la musica barocca
2009
Dopo la Controriforma continua l'espansione e la sublimazione dell'eros, tipica del Rinascimento: fino al 1683 circa; quindi predomina la repressione dell'eros e lo sfruttamento delle energie vitali per la produzione industriale. Alla fluidità sonora della musica rinascimentale e barocca subentra improvvisamente la rigidezza sonora della musica dell'illuminismo e del rococò.
