The efficiency of the incentives for the public buildings’ energy retrofit. The case of the Italian Regions of the “Objective Convergence”

2017

Gli obiettivi di riduzione del consumo energetico e delle emissioni di gas serra, enunciati in molte Direttive europee, hanno posto in risalto la necessità di promuovere interventi di miglioramento dell’efficienza energetica del patrimonio edilizio esistente. Le amministrazioni locali, in particolare, dovrebbero assumersi la responsabilità di diffondere la cultura ambientale anche effettuando interventi di retrofit negli edifici pubblici di loro proprietà, sulla base di diagnosi energetiche degli edifici, di proposte progettuali e di verifiche del raggiungimento della convenienza finanziaria, che può essere agevolata dall’erogazione di incentivi. L’Unione Province d’Italia (UPI) nel 2013, n…

Detection of natural killer T cells in mice infected with Rickettsia conorii.

2013

Little information is available regarding the role of natural killer T (NKT) cells during the early stage of Rickettsia conorii infection. Herein, C3H/HeN mice were infected with the Malish 7 strain of R. conorii. Splenocytes from these mice were analysed in the early stage of the infection by flow cytometry and compared with uninfected controls. Our results showed an increase in NKT cells in infected mice. Additionally, NKT interleukin (IL)-17(+) cells increased three days after infection, together with a concurrent decrease in the relative amount of NKT interferon (IFN)-γ(+) cells. We also confirmed a higher amount of NK IFN-γ(+) cells in infected mice. Taken together, our data showed tha…

Investigation of a Gravel-Bed River’s Pattern Changes: Insights from Satellite Images

2021

Changes in river pattern have been documented in the literature. The recognition of islands and vegetated patches, which is indicative of the evolution processes, requires simultaneous information at different points and at different times and field studies are still difficult and scarce. The present work, focusing the attention on a gravel-bed river, explores the possibility to conduct a first-step pattern changes analysis by identifying the evolution of the morphological features and taking information of islands and vegetated patches from satellite images easily available from Google Earth. The study is conducted by combining the information taken from both the satellite images and the f…

Entropic model application to identify cross-sectional flow effect on velocity distribution in a large amplitude meandering channel

2020

Abstract Literature shows the application of the entropy concept in open channels flow. No existing research has been addressed to the application of the entropy concept for evaluating the effect of secondary flow which especially develops in curved channels. The purpose of this paper is to explore the possibility to evaluate the effect of the secondary flow on the stream-wise velocity distribution starting only from the knowledge of the surface velocity and the entropic concept application. The analysis is conducted with the aid of data collected in a large-amplitude meandering laboratory flume for two different values of the width-to-depth ratio. Results show that the location of the maxi…

Photoluminescent Detection of Human T-Lymphoblastic Cells by ZnO Nanorods.

2020

The precise detection of cancer cells currently remains a global challenge. One-dimensional (1D) semiconductor nanostructures (e.g., ZnO nanorods) have attracted attention due to their potential use in cancer biosensors. In the current study, it was demonstrated that the possibility of a photoluminescent detection of human leukemic T-cells by using a zinc oxide nanorods (ZnO NRs) platform. Monoclonal antibodies (MABs) anti-CD5 against a cluster of differentiation (CD) proteins on the pathologic cell surface have been used as a bioselective layer on the ZnO surface. The optimal concentration of the protein anti-CD5 to form an effective bioselective layer on the ZnO NRs surface was selected. …

Root hydraulic conductivity in three self-rooted and grafted table grape cultivars

2012

<p style="text-align: justify;"><strong>Aim</strong>: Root hydraulic conductivity is one of the main factors that control water flow in the soil-plant system and ultimately affect crop irrigation requirements. This work sets out to estimate root water conductivity for three self-rooted or grafted table grape cultivars.</p><p style="text-align: justify;"><strong>Methods and results</strong>: We evaluated root water conductivity of the cultivars ‘Black Magic’, ‘Matilde’ and ‘Victoria’ grafted onto 1103 Paulsen rootstock or self-rooted. Measurements were performed on two-year-old table grapes grown in pots filled with pumice. Root water conductivity wa…

Production and energetic performance of Carthamus tinctorius L. in the Mediterranean environment

2012

One of the most important aspects when managing an agro-energy crop is the energy gain factor, that is, the surplus in energy which remains following an appraisal of the relevant inputs and outputs. This aspect is of fundamental importance when choosing a species in a particular growth environment as it gives crucial information on the economic and energetic feasibility of a species and allows us to evaluate potential costs in order to obtain a given production and energy performance. In the agro-energy sector, this indicator is not always included in the evaluation process, making the agronomic and energy results obtained often incomplete. In the Mediterranean area, one potential crop for …

Can the odours modulate salivation? Impact of the nature of the odorant

2015

Introduction :Saliva plays numerous roles in the oral cavity, especially in digestion and taste perception. It is well admitted that tastants are effective stimuli of salivation and that the salivary response (flow and composition) depends on the nature of the tastant. However, the impact of odours on salivation is poorly known and not consensual. Odours are the first chemical signal informing about food palatability before ingestion. In this context, it is necessary to understand if the salivary secretions are modulated in function of this sensory signal. The aim of this study is to compare the salivary flow response after stimulation by different odours having different hedonic values.Mat…
