Il concetto di potestas nell'editto 'de noxalibus actionibus'. Per una ricostruzione della fase in iure del processo nossale classico
2017
Della fase in iure del processo nossale classico i testi raccolti nei titoli 2.9 e 9.4 dei Digesta Iustiniani, rubricati rispettivamente ‘Si ex noxali causa agatur, quemadmodum caveatur’ e ‘De noxalibus actionibus’, non ci tramandano una descrizione compiuta e lineare. L’abbozzo di una sintesi si può invero rinvenire in alcuni squarci della giurisprudenza severiana,1 ma non pochi passaggi restano nell’ombra, del tutto taciuti o non adeguatamente esplicitati. Spetta quindi all’interprete, come con i frammenti di un mosaico – un mosaico nella specie intricatissimo –, cercare di ordinare i vari ‘pezzi’, raccordarli logicamente fra loro e restituire, se possibile, un insieme coerente. Il compit…
Investigating Avatar Influence on Perceived Cognitive Load and Bimanual Interactions with Touchless Interfaces
2017
In recent years, touchless-enabling technologies have been more and more adopted for providing public displays with gestural interactivity. This has led to the need for novel visual interfaces aimed at solving issues such as communicating interactivity to users, as well as supporting immediate usability and "natural" interactions. In this paper, we focus our investigation on a visual interface based only on the use of in-air direct manipulations. Our study aims at evaluating whether and how the presence of an Avatar that replays user’s movements may decrease the perceived cognitive workload during interactions. Moreover, we conducted a brief evaluation of the relationship between the presen…
Differential toxicity of simazine and diuron to Torilis arvensis and Lolium rigidum
1990
Summary: In a soil application, Torilis arvensis was nearly as susceptible as Lolium rigidum to simazine but was 18-fold more tolerant to diuron. Treat ment with diuron inhibited photosynthesis in L. rigidum but had only a limited effect in T. arvensis although chloroplasts isolated from both species displayed similar susceptibility. 14C-diuron degradation in plants was limited, with the formation of conjugates of mono-methyl-diuron in T. arvensis and N-dealkylated derivatives of diuron in L. rigidum. 14C-diuron entered the roots and was translocated throughout the leaves of L. rigidum but was restricted to stems, leaf petioles and leaf veins of T. arvensis. This difference in transport pat…
Macrophage migration inhibitory factor is critically involved in basal and fluoxetine-stimulated adult hippocampal cell proliferation and in anxiety,…
2011
Intensive research is devoted to unravel the neurobiological mechanisms mediating adult hippocampal neurogenesis, its regulation by antidepressants, and its behavioral consequences. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that is expressed in the CNS, where its function is unknown. Here, we show, for the first time, the relevance of MIF expression for adult hippocampal neurogenesis. We identify MIF expression in neurogenic cells (in stem cells, cells undergoing proliferation, and in newly proliferated cells undergoing maturation) in the subgranular zone of the rodent dentate gyrus. A causal function for MIF in cell proliferation was shown using genetic (M…
Pseudo-haptic Controls for Mid-air Finger-based Menu Interaction
2019
Virtual Reality (VR) is more accessible than ever these days. While topics like performance, motion sickness and presence are well investigated, basic topics as VR User Interfaces (UIs) for menu control are lagging far behind. A major issue is the absence of haptic feedback and naturalness, especially when considering mid-air finger-based interaction in VR, when "grabbable" controllers are not available. In this work, we present and compare the following two visual approaches to mid-air finger-based menu control in VR environments: a planar UI similar to common 2D desktop UIs, and a pseudo-haptic UI based on physical metaphors. The results show that the pseudo-haptic UI performs better in t…
Field testing parameter sensitivity of the two-term infiltration equation using differentiated linearization
2003
Knowledge of soil hydraulic conductivity in the vadose zone is important in many agronomic, engineering and environmental areas. Transient tension infiltrometer experiments can be used to estimate the hydraulic conductivity, K0, corresponding to a given pressure head by the single-test (TST) method that uses the coefficients C1 and C2 of the two-term infiltration equation. The “Differentiated Linearization” (DL) method has been proposed to estimate these coefficients when a layer of contact material is used for the experiment. A field test of the DL and TST methods was conducted on a sandy loam and a clay soil. Eliminating the early-time influence of the contact layer was easy when the sorp…
Wi-Dia: Data-Driven Wireless Diagnostic Using Context Recognition
2018
The recent densification of Wi-Fi networks is exacerbating the effects of well-known pathologies including hidden nodes and flow starvation. This paper provides an automatic diagnostic tool for detecting the source roots of performance impairments by recognizing the wireless operating context. Our tool for Wi-Fi diagnostic, named Wi-Dia, exploits machine learning methods and uses features related to network topology and channel utilization, without impact on regular network operations and working in real-time. Real-time per-link Wi-Fi diagnosis enables recovering actions for context-specific treatments. Wi-Dia classifier recognizes different classes of interference; it is jointly trained us…
Prediction of soil texture distributions using VNIR-SWIR reflectance spectroscopy
2013
Abstract Reflectance spectroscopy provides an alternate method to non-destructively characterize key soil properties. Different approaches, including chemometrics techniques or specific absorption features, have been proposed to estimate soil properties from visible and near-infrared (VNIR, 400-1200 nm) and shortwave infrared (SWIR, 1200-2500 nm) reflectance domains. The main goal of this study was to test the performance of two distinct methods for soil texture estimation by VNIR-SWIR reflectance measurements: i) the Continuum Removal (CR) technique that was used to correlate specific spectral absorption features with clay, silt and sand content, and ii) the Partial Least-Squares Regressio…

Regarding Apionidae, 8 of 9 species recorded from the Kampinos National Park in literature, were confirmed to occur there. Perapion oblongum (GYLL.) has been recorded from the Mazovian Lowland for the first time
Introduzione al volume Poteri criminali e crisi della democrazia
2011
Il saggio introduce al volume che raccoglie gli atti di un Convegno internazionale dal titolo "Poteri criminali e crisi della democrazia". Il libro prova ad esplorare le relazioni tra organizzazioni criminali mafiose, mondo della politica, sistema produttivo e mondo dell’informazione, cercando di individuare e comprendere le caratteristiche di un sistema di poteri in cui è sempre più tenue il confine tra lecito e illecito. Perché da un lato, le mafie trovano sempre maggiori e più complesse forme di compenetrazione con la politica e con l’economia; d’altro lato, le istituzioni non sempre riescono ad attivarsi per garantire presidio e trasparenza dei processi decisionali pubblici.
