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…

Contrasto tra città e campagna nella Polonia rinascimentale sullo sfondo delle aspirazioni culturali degli ex‑studenti e dei viaggiatori polacchi a P…

2020

Głębokie rozumienie istoty opozycji pomiędzy światem kultury, reprezentowanym przez miasto, oraz natury, związanej z życiem na wsi, uchwycone zostało na fresku Tycjana z 1511 roku, przedstawiającym cud Świętego Antoniego, a rozgrywającym się na styku tych dwóch przestrzeni. Tak wyrafinowane postrzeganie tego kontrastu, charakterystyczne dla renesansu włoskiego, nie miało swojego odzwierciedlenia w Polsce, gdzie miasta oraz związane z nimi funkcjonowanie kultury dworskiej nie miały równie bogatej reprezentacji. Masowy kontakt studentów polskich, przybywających w okresie renesansu zwłaszcza do Padwy, z kulturą willi weneckich miał jednak ogromny wpływ zwłaszcza na ideowe próby odzwierciedleni…

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 …

Representations of the Life-giving Spring feast in Romanian iconography

2021

This article explores the development of the theme of the Life-giving Spring in Byzantine iconography. The path towards its establishment was initiated at the moment when a representation rule, an original convention was set. Thereafter, because of its diffusion in time and space, the theme became enriched by particular mentalities and sensibilities of the epochs and the communities that adopted it as a form of devotion for the Virgin Theotokos. As a result, the representations we have known so far are extremely varied. Contribution: The final purpose of this approach, as well as its contribution, is to highlight the diverse unity of the iconographic tradition and illustrate both the evolut…

Le sculture lignee

2023

Il contributo indaga le sculture lignee ubicate nella chiesa di Santa Maria la Porta di Geraci Siculo. Si tratta di opere eseguite dal XVI al XVII secolo da scultori attestati non solo nel borgo madonita ma anche in altre realtà isolane. Ogni manufatto è collocato nella pertinente temperie culturale The contribution investigates the wooden sculptures located in the church of Santa Maria la Porta in Geraci Siculo. These are works performed from the 16th to the 17th century by sculptors attested not only in the Madonie village but also in other island realities. Each artifact is placed in the pertinent cultural climate

Differential Effects of Mindfulness-Based Intervention Programs at Work on Psychological Wellbeing and Work Engagement.

2021

Two different mindfulness-based interventions were deployed in a sample of white-collar workers to explore the differential effects on different facets of mindfulness, dimensions of psychological wellbeing, work engagement, performance, and stress of a participant. A total of 28 participants completed one of the different programs, and their results were compared between groups and against 27 participants randomly allocated to a waiting list control group. Results suggest both mindfulness intervention programs were successful at increasing the levels of psychological wellbeing, work engagement, and performance of the participants, as well as decreasing their levels of stress. Significant di…

Effects of a Job Crafting Intervention Program on Work Engagement Among Japanese Employees: A Randomized Controlled Trial

2020

Objective The current randomized controlled trial investigated the effectiveness of a job crafting intervention program on work engagement as the primary outcome and job crafting as the secondary outcome among Japanese employees. Methods Participants who met the inclusion criteria were randomly assigned to an intervention group (n = 138) or a control group (n = 143). The job crafting intervention program provided only to the intervention group consisted of two 120-minute group sessions with e-mail or letter follow-up. Outcomes were assessed at baseline and at 3-month and 6-month follow-up in both groups. Results In the total sample, the job crafting intervention program showed a non-signifi…
