Study of quantitative and qualitative variations in essential oils of Sicilian oregano biotypes
2015
Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0–54.4%), γ-terpinene (9.8–30.5%), ρ-cymene (5.2–18.7%), α-terpine…
IEEE Access Special Section Editorial: Exploiting the Benefits of Interference in Wireless Networks: Energy Harvesting and Security
2018
Interference used to be viewed as a harmful factor in wireless networks, which can reduce the quality of information transmission. To combat against interference, many interference management techniques have emerged. Due to the latest research advances, interference (or noise) can also be exploited to offer some benefits to wireless networks. The first aspect is that interference in multi-user networks can be collected as a green power supply for the transceivers, known as wireless energy harvesting. Another application is that one can generate artificial noise to disrupt the adversarial eavesdropping, and guarantee the security of wireless networks. Therefore, conventional interference man…
Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
2016
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
Granica województwa a powiązania regionalnym transportem kolejowym na przykładzie Wielkopolski
2022
W 2000 r. w Polsce rozpoczął się proces regionalizacji kolei. Odpowiedzialność za przewozy wojewódzkie przeniesiono na samorządy wojewódzkie. Przedmiotem badania były powiązania międzywojewódzkie pociągami osobowymi Wielkopolski i 7 województw ościennych (razem 33 trasy). Na 15 z nich prowadzone są przewozy pasażerskie. Liczba połączeń jest zróżnicowana. W planach transportowych 19 linii opisywanych jest w obydwu dokumentach (Wielkopolska i sąsiadujący region). 8 jest pominiętych, a 6 znajduje odniesienie w jednym z planów. Układ komunikacyjny powinien być koordynowany wzajemnie przez sąsiadujące samorządy. Planowane połączenia są różnie traktowane przez województwa. Tworzenie systemu trans…
Contre la fausse objectivité, le perspectivisme assumé ? le reportage « gonzo » de Goldin, Clark, D’Agata, Tillmans contre la photographie « document…
2019
International audience; Après 1945, un certain nombre de praticiens de la « photographie plasticienne »privilégièrent le reportage « communautaire » : une plongée, sur le long terme, au sein d’ungroupe d’individus, souvent connus, voire intimes, du photographe, qui loin de se placercomme un témoin neutre, activait le mécanisme de l’observation participante chère àl’ethnographie. Larry Clark en fournit un exemple avec la série Tulsa (1971), la premièred’une longue lignée. Nan Goldin amplifia d’autant l’inclusion de l’autrice par la pratique del’autoportrait en situation dans The Ballad of Sexual Dependency (1981-1996). Plus tard desartistes comme Antoine d’Agata ou Wolfgang Tillmans poursuiv…

Importance of millipedes (Diplopoda) in the autumn-winter diet of Scolopax rusticola
2019
Authors examined the autumn-winter diet of the woodcock Scolopax rusticola from 407 gizzard samples originating from Crimea and Italy, resulting in a high number of millipedes (Diplopoda) in all the samples; this prey item was particularly important in terms of weight percentage. The authors consider that calcium, highly present in millipedes, should be an important source for the woodcocks’ metabolism during the autumn-winter seasons.
Low mimosine content and nutrient-rich foliage of two Leucaena leucocephala varieties: a potential fodder resource in Mediterranean agroforestry syst…
2022
Leucaena leucocephala is worldwide used for wood production, reforestation and for feeding livestock. To assess the potential use of leucaena for animal nutrition, we analysed the composition of methanolic extracts of leaf samples of two varieties occurring in Sicily (Mediterranean area), also determining the presence of mimosine.
Work commitment and engagement in south Italian volunteers
2009
Objectives. Recent research on volunteering has increased its interest in integrating different theoretical models such as motivational and socio-psychological ones. The current research replicates and extends a Swiss survey (Guntert, 2008) among a sample of Italian volunteers. The aim was to examine the antecedents (mainly in terms of motivational factors and identification) of outcomes such as commitment and engagement towards volunteering. Methods. To examine these antecedents and the outcomes, a questionnaire was administered to a sample of 165 young Italian adults who were engaged in various voluntary associations in south Italy (Campania and Sicilia). Results. Our analyses, underlinin…
