In situ riboflavin fortification of different kefir-like cereal-based beverages using selected Andean LAB strains.
2018
Cereal-based functional beverages represent social, economic, and environmental sustainable opportunities to cope with emerging trends in food consumption and global nutrition. Here we report, for the first time, the polyphasic characterization of three cereal-based kefir-like riboflavin-enriched beverages, obtained from oat, maize and barley flours, and their comparison with classical milk-based kefir. The four matrices were successfully fermented with commercial starters: i) milk-kefir and ii) water-kefir, proving the potential of cereal ingredients in the formulation of dairy-like fermented beverages with milk-kefir starter behavior better in these matrices. In the light of their potenti…
A Survey on LoRa for Smart Agriculture: Current Trends and Future Perspectives
2023
This paper provides a survey on the adoption of LoRa in the agricultural field, and reviews state-of-the-art solutions for Smart Agriculture, analyzing the potential of this technology in different infield applications. In particular, we consider four reference scenarios, namely irrigation systems, plantation and crop monitoring, tree monitoring, and livestock monitoring, which exhibit heterogeneous requirements in terms of network bandwidth, density, sensors’ complexity, and energy demand, as well as latency in the decision process. We discuss how LoRa-based solutions can work in these scenarios, analyzing their scalability, interoperability, network architecture, and energy-efficiency. Fi…

Il Polar prima del Polar: il poliziesco italo-americano tra fine Ottocento e gli anni Trenta del Novecento
2018
Tra la fine dell’Ottocento e gli anni Trenta del Novecento, alcuni Italiani immigrati negli Stati Uniti – quali, fra gli altri, Bernardino Ciambelli, Italo Stanco, Garibaldi Marto Lapolla, Louis Forgione, nonché il sodalizio letterario costituito da Michael Fiaschetti e Prosper Buranelli – si sono cimentati nel genere del poliziesco con alcuni testi che, partendo da alcune delle caratteristiche tipiche del Mystery, quali la serializzazione e l’incardinamento della fabula in uno specifico contesto urbano, insieme ad alcuni degli elementi caratteriali dei personaggi dell’Hard boiled non perdono mai di vista la peculiare ‘missione’ di denuncia politica, economica e sociale. Facendo del problem…
Federica Marzi: In terra straniera. Rappresentazioni e scritture dell’altro nell’emigrazione italiana in Germania
2016
In Terra straniera, 2014 bei Campanotto, Udine veröffentlicht, erscheint in der von Elvio Guagnini herausgegebenen Reihe ‚Italianistik’. Der Band erweist sich als ein Bericht über eine lange Reise, die die Italiener 1955 begannen und die bisher noch nicht zu Ende ist. Eine Reise in das fremde Land Deutschland, das schon damals zum begehrten Ziel vieler Menschen geworden und es bis heute geblieben ist. Die vorliegende Monographie ist die Bearbeitung der Dissertation Federica Marzis. Diese wurde im Rahmen des internationalen Doktorats in Scienze Umanistiche (Studiengang Italianistik) dank einer Kooperation zwischen der Universität Triest und der Heinrich-Heine-Universität Düsseldorf verfasst.…
MR3785684 Reviewed Liu, Ai Fang(PRC-NAA); Li, Peng Tong(PRC-NAA) K-fusion frames and the corresponding generators for unitary systems. (English summa…
2018
Given an operator K∈B(H), in this paper the authors introduce K-fusion frames as a generalization of fusion frames, defined as a sequence {Wi} of closed subspaces of the Hilbert space H. For K=1, this becomes a fusion frame. They prove some properties of K-fusion frames, based on considering the operator K and the frame operators. In the last section, for a unitary system U, the authors define a K-fusion frame generator in a way similar to the frame vectors for unitary systems. Some properties and characterization theorems are derived for operators in the generalized local commutant of U.
MICRORNA-21 EXPRESSION IN VESTIBULAR SCHWANNOMA: POTENTIAL EFFECT ON GROWTH AND POSSIBLE PROGNOSTIC FACTOR
2011
Background: Vestibular schwannomas are benign slow growing tumors arising from VIII cranial nerve. They are potential life threatening benign tumor because of intracranial located. The management could be surgical or conservative, but, left untreated, the tumor preserve the possibility to further growth and complication may arise. The natural history is however not predictable and prognostic factor to select patients manageable conservatively should be studied. The molecular pathways that lead to tumorigenesis and growth are not completely defined and a role could be played by microRNA. Elevated levels of microRNA-21 may contribute to tumor growth by deregulating the tumor suppressor phosph…
EMORRAGIA IN TUMOR DA NEURINOMA DELL’VIII N.C. & SIMDROMI PARALITICHE ANTERIORE E POSTERIORE IMPROVVISA: SEMEIOTICA RADIOLOGICA
2011
Gli autori riportano un raro caso clinico di una paziente di 77 anni che giunge alla nostra osservazione in regime di urgenza per vertigine improvvisa associata a nausea e vomito, stato confusionale, atassia, paralisi completa del VI nervo cranico di destra con strabismo convergente, segni di sofferenza del IX, X ed XI nervo cranico omolaterali all’abducente e iniziale comparsa di segni statici e dinamici di paralisi periferica del VII nervo cranico di destra. L’insorgenza improvvisa di Sindromi paralitiche associate, anteriori e posteriori, ha indirizzato verso il sospetto di lesione occupante spazio a sede in fossa cranica posteriore/tronco encefalo richiedendo pertanto l’ausilio della di…
IMAGING OF VESTIBULAR SCHWANNOMA [Chapter 4]
2020
Lesions of the cerebellopontine angle and internal auditory canal are a frequent finding in neuroradiological examinations and their detection may represent a diagnostic challenge. Among these lesions, vestibular schwannomas and meningiomas are certainly the most frequent and account for up to 90% of all cerebellopontine angle tumours. The remaining ones are a group of lesions arising from the different structures found in these anatomical regions such as haemangiomas, lipomas, lymphomas, facial nerve tumours, and aneurysms. This chapter will introduce this topic focusing on a practical coverage of the typical and atypical neuroradiological signs that will drive towards the most correct dif…
Electron transfer mechanism in Shewanella loihica PV-4 biofilms formed at graphite electrode
2012
Abstract Electron transfer mechanisms in Shewanella loihica PV-4 viable biofilms formed at graphite electrodes were investigated in potentiostat-controlled electrochemical cells poised at oxidative potentials (0.2 V vs. Ag/AgCl). Chronoamperometry (CA) showed a repeatable biofilm growth of S. loihica PV-4 on graphite electrode. CA, cyclic voltammetry (CV) and its first derivative shows that both direct electron transfer (DET) mediated electron transfer (MET) mechanism contributes to the overall anodic (oxidation) current. The maximum anodic current density recorded on graphite was 90 μA cm − 2 . Fluorescence emission spectra shows increased concentration of quinone derivatives and riboflavi…
