Fresh-Cut Mangoes: How to Increase Shelf Life by Using Neem Oil Edible Coating
2022
The mango is the most widely cultivated tropical fruit. Fresh-cut mango is very useful, but it is very perishable. The purpose of this study was to highlight the effects of neem oil on fresh-cut mango fruits kept for 9 days at 4 ± 1 °C and 80 ± 5% relative humidity. The neem plant (Azadirachta indica) has numerous antioxidant and antibacterial properties. Despite this, very few studies have been carried out on neem oil added to edible coatings (EC) to retard ripening processes. Two formulations were tested: EC1 (hydroxypropyl methylcellulose + CaCl2) and EC2 (hydroxypropyl methylcellulose + CaCl2 + neem oil), both compared with an untreated sample (control). Physicochemica…
Conversational Gatekeeping : Social Interactional Practices of Post-Publication Gatekeeping on Newspapers’ Facebook Pages
2022
Digital platforms, such as social media networks, have become intertwined in the news ecosystem, leading news media to lose their role as the sole gatekeeper in the public space. This development has given an active voice to audiences and turned journalism more into conversations between journalists and their audiences. The starting observation for this article was that alongside journalists, platforms and audiences play a part in the gatekeeping process that takes place post-publication, and therefore we need to gain a better understanding of this triadic relationship. Furthermore, as conversations are one of the main functions of social media platforms, more understanding of the role of s…
Measurement and communication interfaces for distributed generation in smart grids
2013
The aim of this work is to perform a feasibility study on the measurement and communication strategies for the development of a new generation of interface devices for distributed generators and their integration on smart grids. The communication system can use one or more technologies, at the various levels, creating a low cost network infrastructure, in the framework of a SCADA (Supervisory Control and Data Acquisition) architecture. As regards the measurements, the attention is focused on the anti-islanding protection, based on a hybrid solution, which makes use of local measurements and communications with the grid, at both MV and LV level by employing the PLC technology. Some simulatio…
An interface protection system with power line communication for distributed generators remote control
2014
The aim of this work is to present a narrow band power line communication (NB-PLC) interface protection system (IPS) for distributed generators (DGs); it has been developed according to the current standard CEI 0-21 and the requirements for smart grid applications. For such applications, the new IPSs have to implement new intelligent functions such as remote monitoring and control of DGs and Energy Storage Systems (ESSs) inverters, not only in terms of disconnection but also of voltage regulation and power modulation by the utility control. The main feature of the developed IPS is the ability to interact with both the grid and the DG's and ESS's inverters. In fact, it can communicate with t…
Prefaces in medical dictionaries: from moves to rhetorical analysis
2017
Medical dictionaries represent, among the other things, an important pedagogic genre (Swales 1995, Bhatia, 1997, Hyland 2000) within academic education, since they are the means through which professional writers talk about their disciplines and address to scholars. The preface sections are of the utmost importance since, among several functions, they (should) attract and orient the readers (Azar, 2012). This paper describes the macro structure of preface sections in fourteen English dictionaries related to the field of medicine and investigates on the rhetorical and discursive devices employed in these texts to establish the importance of the author's work. In addition, the paper questions…
Effect of Hot Dip Galvanized Steel Surface Chemistry and Morphology on Titanium Hexafluoride Pretreatment
2017
Titanium hexafluoride pretreatments are known to improve paint adhesion and function as a barrier between the coating and the hot dip galvanized (HDG) steel surface. Interactions at the zinc/pretreatment interface are of utmost importance for the formation of pretreatment layers and the corrosion resistance of color coated hot dip galvanized steels. Removal rate of inert aluminum oxide from HDG steel samples by chemical dissolution was studied. XPS measurements showed that the surface Al2O3 layer thickness decreased rapidly already at mild alkaline cleaning, while complete removal of Al required severe etching. Low reactivity of an Al2O3-rich surface was confirmed by impaired formation of a…

Quasiconformal Jordan Domains
2020
We extend the classical Carath\'eodory extension theorem to quasiconformal Jordan domains $( Y, d_{Y} )$. We say that a metric space $( Y, d_{Y} )$ is a quasiconformal Jordan domain if the completion $\overline{Y}$ of $( Y, d_{Y} )$ has finite Hausdorff $2$-measure, the boundary $\partial Y = \overline{Y} \setminus Y$ is homeomorphic to $\mathbb{S}^{1}$, and there exists a homeomorphism $\phi \colon \mathbb{D} \rightarrow ( Y, d_{Y} )$ that is quasiconformal in the geometric sense. We show that $\phi$ has a continuous, monotone, and surjective extension $\Phi \colon \overline{ \mathbb{D} } \rightarrow \overline{ Y }$. This result is best possible in this generality. In addition, we find a n…
Cambiamenti nell'uso dei soggetti clitici veneti: il ruolo del contatto con l'italiano
2018
This chapter discusses the results of a series of data on the syntax of subject clitic pronouns in Venetan dialects. The data were gathered through a crowdsourcing tool (google modules), and more than 700 participants took part in the inquiry. The data collection asked for grammaticality judgements on a series of contexts. The main research question was whether the syntax of subject clitics is changing in the language of the younger generation: this question is particularly important because the distribution of the Venetan varieties througout the Veneto region is changing, due to the increasing influence and presence of Italian, which is the L1 of most of the younger speakers. The results s…
Social Science Research in Southeast Asia : the Challenges of Studying Parliamentary Institutions
2019
This paper introduces the challenges of studying parliamentary institutions in Southeast Asia. My focus of research is in three countries’ institutions: national parliaments of Indonesia, Malaysia and Singapore. While in Southeast Asia, it is widely known that studying issues of politics and institutions face challenges – compared to studying culture, for example, this view is arguably no longer valid, however with certainqualification.The comparison of parliamentary tradition between three countries – based on observation of the plenary session - reveals that the effectiveness of parliamentary works is related to parliamentary procedure, and even to the culture of work in the countries.
