Il carsismo nei gessi della Sicilia

2018

Le aree carsiche gessose della Sicilia hanno attirato l’attenzione di naturalisti e geologi sin dalla seconda metà del 1800. Tuttavia, gli studi sul carsismo nei gessi non hanno visto una costante evoluzione nel tempo; infatti, dopo un lungo periodo di indifferenza, è solo a partire dagli anni ’80 del secolo scorso, che si è assistito ad un rinnovato interesse verso questa tematica, inizialmente grazie alla realizzazione di numerose campagne di esplorazione in diverse aree carsiche gessose della Sicilia da parte di alcuni gruppi speleologici siciliani, e in un secondo momento grazie all’interesse mostrato dall’Istituto di Geologia (oggi Dipartimento di Scienze della Terra e del Mare) dell’U…

FORMULAZIONE DI INCAPSULANTI POLIMERICI PER MODULI FOTOVOLTAICI BIFACCIALI HJT

2022

Il crescente interesse per la salvaguardia dell’ambiente, principalmente motivato dai disastri naturali che sono incorsi numerosi nell’ultimo ventennio, ha dato un’ulteriore spinta alla ricerca sulle fonti di energia “green” rinnovabile non derivanti da combustibili fossili, che permetta all’uomo di continuare a provvedere ai propri fabbisogni in maniera più “rispettosa”. Infatti, le fonti energetiche rinnovabili che il nostro pianeta ci mette a disposizione sono innumerevoli: dall’energia meccanica ed elettrica prodotta dal vento, alle biomasse, la cui combustione in appositi impianti permette generazione termica e cogenerazione di calore ed elettricità; l’energia prodotta dalle maree e da…

Polar Wax as Adhesion Promoter in Polymeric Blend Films for Durable Photovoltaic Encapsulants

2022

Technological developments in the solar photovoltaic field must guarantee the high performance and low deterioration of solar cells in order for solar power plants to be more efficient and competitive. The solar cell needs comprehensive protection offered by a polymeric encapsulant, which improves UV stability, reduces water and moisture absorption, reduces oxygen and vapor permeability and enhances mechanical resistance. Moreover, high transparency and adhesion yields improved the solar panel performance. The current work analyzes polymeric films based on poly(ethylene-co-vinyl acetate) (EVA) and polyolefin (PO) for photovoltaic encapsulant use (the high temperature resistance is improved …

Per una via siciliana dei gessi. Quando le parole portano alle cose

2023

Secondo il metodo Wörter und Sachen, parole e cose, suoni e referenti, devono essere studiati insieme. Questa simbiosi ha particolare necessità di essere applicata quando si tratti di cultura materiale. Il contributo è la storia di un’esperienza di indagine sul campo, svolta in un periodo di tempo di circa 15 anni, che ha riguardato le parole del gesso e le cose di gesso nella Sicilia centrale. L’individuazione di questo ambito di studio è stata parallela, ma marginale, rispetto ad una più significativa esperienza dialettologica relativa al lessico zolfifero. Eppure, grazie a questo approfondimento, sono emerse conoscenze inedite dal punto di vista linguistico ed etnodialettale, tali da avv…

Adhesive capsulitis of the shoulder: laser CO2 vs intra-articular injections

2012

Analysis of our data shows that the functional rehabilitation associated with the CO2 laser causes a greater reduction in pain, better recovery of joint ROM and increase in muscle strength compared to treatment associated with injections of corticosteriods

Adhesive capsulitis in a patient affected by KBG Syndrome

2021

Background and Case presentation: KBG syndrome is a multiple congenital anomaly syndrome with variable presentation. Many physical anomalies also affect the orthopaedic field. We present a case of a young woman with diagnosis of KBG syndrome that is also affected by joint stiffness and adhesive capsulitis to the shoulders. Discussion: Many other cases have been reported to present joint stiffness and formation of keloids. Adhesive capsulitis is known to be related to autoimmune pathologies and endocrinological disorders. KBG syndrome is caused by heterozygous mutation in ANKRD11 gene and few patients with hypermobility of the joints have also been reported. Conclusions: The KBG syndrome mig…

First report of Antigastra catalaunalis on sesame in Greece.

2017

Τον Αύγουστο του 2016, καταγράφηκαν σοβαρές προσβολές σε καλλιέργειες σουσαμιού από το έντομο Antigastra catalaunalis (Duponchel) (Lepidoptera: Crambidae) σε αγροτικές περιοχές της Περιφερειακής Ενότητας Δράμας. Το A. catalaunalis είναι ένας σημαντικός εχθρός της καλλιέργειας του σουσαμιού σε περιοχές όπου αυτό καλλιεργείται. Παρατηρήθηκαν συμπτώματα προσβολής από τις προνύμφες του εντόμου σε φύλλα, βλαστούς και κάψες. Οι προσβολές καταγράφηκαν σε όλους τους αγρούς με καλλιέργεια σουσαμιού που επιθεωρήθηκαν, με επίπεδα προσβολής υψηλά τα οποία προκάλεσαν οικονομική απώλεια. Στο βαθμό που γνωρίζουμε, αυτή είναι η πρώτη αναφορά σοβαρών προσβολών σουσαμιού από το Α. catalaunalis στην Ελλάδα.

The formation of long-term unemployed young adults’ emotional capital during childhood : a Bourdieusian approach to emotional harm

2019

This article focuses on the long-term formation of unemployed young adults’ emotional capital and the development of emotional dispositions during childhood. We use Bourdieu’s work and the concept of emotional capital to draw attention to the emotional dynamics of family and peer relations during childhood. Emotional capital is related to parents’ emotional involvement and investment in the child’s well-being, and it encompasses emotional skills and assets that children can attain from family relations. The concept of emotional capital allows an examination of the child’s family and close environment, which shape the development of actors’ emotional inclinations and tendencies. Our data con…

Towards a checklist of the Italian gypsophilous vascular flora.

2016

The strict relationship between plants and particular types of substrate has long been known to botanists and plant ecologists who have dealt with this issue. The peculiar flora growing on Italian gypsum substrates has been underlined since the nineteenth century (1, 2, 3). The concept of plant gypsophily can be defined as the exclusiveness or marked preference for living on gypsum outcropping rocks. Thus, only those plant species which show preference, or even exclusivity, for gypsum substrates, should be classified as gypsophilous (4). The main aim of this research has been to provide a checklist of the Italian gypsophilous flora. The study was made possible through international collabor…
