Vinificazione in bianco in presenza di chips di quercia di origine e livello di tostatura diversi

2011

Some musts from Grillo grapes, a cultivar autochthonous of western Sicily, fermented with medium toasted American oak chips or with non toasted French oak chips (Classic Line – HTS enology) have been vinified. the wines were significantly different as regards the contents in volatile and non volatile compounds extracted from American and French oak chips. a slight increase in alcoholic fermentation rate and in some cases a higher content of ethyl esters and medium chain fatty acids, were observed in musts charged with chips, independently of their origin. In wines obtained from musts charged with french medium toasted oak chips, the content in furans was higher (5-methylfurfural, trans-meth…

Wielkie Księstwo Litewskie w relacjach berlińskich Philipa Plantamoura z lat 1700–1703

2019

Ważnym elementem w obecnych badaniach historycznych jest analiza relacji dyplomatycznych dotyczących dawnej Rzeczypospolitej w tym Wielkiego Księstwa Litewskiego. Ukazują one dzieje państwa oraz jego politykę wewnętrzną i zagraniczna z innej perspektywy historycznej. W 1700 r. wybuchła Wielka Wojna Północna, która zmieniła układ sił politycznych w Europie Środkowo Wschodniej na kolejne dziesięciolecia. Dyplomaci obcych dworów byli zainteresowani tą wojną, w tym Philipp Plantamour, sekretarz ambasadora angielskiego w Berlinie. Przesyłał on do Londynu swoje relacje, w których umieszczał nie tylko informacje dotyczące działań militarnych w czasie wojny, ale także te dotyczące najważniejszych r…

Importazione massale di dati in Wikiplantbase: l'esperienza con Wikiplantbase #Sicilia

2019

Il progetto Wikiplantbase è stato avviato nel 2013 al fine di offrire un sistema dove caricare record floristici georeferenziati, liberamente accessibili via internet. Sino ad allora, infatti, esistevano un gran numero di banche dati online sulla nomenclatura, tassonomia, erbari, specie aliene, vegetazione, numeri cromosomici e sequenze di DNA, ma non vi era facile accesso ai dati floristici a grande dettaglio geografico. I record floristici costituiscono i dati primari sulla biodiversità utili per qualsiasi ricerca di biologia vegetale. Al fine di aumentare i dati sulla Sicilia disponibili in Wikiplantbase, si sono elaborati e standardizzati alcuni dei dati liberamente accessibili dal sito…

Agronomical evaluation of Sicilian biotypes of Lavandula stoechas L. spp. stoechas and analysis of the essential oils

2015

The aim of this study was to characterize wild lavender, which was collected in three different areas of Sicily (Italy),according to agronomic and chemical evaluation. The collection sites were located in Pantelleria island, Partinico (a warm sub-area of Lauretum) and Castelbuono (a middle sub-area of Lauretum). All the populations were identified as Lavandula stoechas L. ssp. stoechas. Essential oils were extracted by hydrodistillation and analyzed by gas chromatography– flame ionization detector (GC–FID) and GC–mass spectrometry (GC–MS). GC–FID and GC–MS analyses permitted the identification of 101 components from the essential oils. We analyzed only the flowers and leaves of L. stoechas …

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…

Quando Gilgameš taglia i “cedri”. Gli alberi nell’immaginario mitologico mesopotamico

2021

In the Sumerian and Akkadian mythological literature, the ruler of the city of Uruk, Gilgameš, uproots and/or cuts down trees on several occasions: the ḫalub-tree (mahaleb cherry) linked to the goddess Inanna and the eren (juniper)/erēnu (cedar) trees of the Forest guarded by Ḫuwawa. These trees should be understood as elements of a wider "wilderness", with which they share a powerful and ambiguous ontological otherness, as opposed to the city and the country of Sumer. In order to become useful, this otherness must be conducted in the city and subject to processes of organization. This article illustrates the symbolic implications of the uprooting, cutting down and subsequent transport of t…

A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network

2016

The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…

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 …

Energy Efficient Optimization for Wireless Virtualized Small Cell Networks With Large-Scale Multiple Antenna

2017

Wireless network virtualization is envisioned as a promising framework to provide efficient and customized services for next-generation wireless networks. In wireless virtualized networks (WVNs), limited radio resources are shared among different services providers for providing services to different users with heterogeneous demands. In this paper, we propose a resource allocation scheme for an orthogonal frequency division multiplexing-based WVN, where one small cell base station equipped with a large number of antennas serves the users with different service requirements. In particular, with the objective to obtain the energy efficiency in the uplink, a joint power, subcarrier, and antenn…
