Validation of a mechanistic model for predicting fruit scab infection on different loquat cultivars

2017

[EN] Scab, caused by Fusicladium eriobotryae, is the main disease affecting loquat (Eriobotrya japonica) in the Mediterranean basin. A mechanistic epidemiological model developed in Spain to predict infection of loquat fruit by conidia was assessed in the main loquat cultivated area of Italy (Sicily). A 3-year study (2014-2016) was carried out in an experimental orchard on three loquat cultivars: Algerie, Peluche and San Filipparo. For each cultivar, output of the model was compared with observed scab development on fruits. The scab epidemics observed were different in different years and cultivars, representing a suitable data set for model validation. The model correctly predicted loquat …

La volontà e il corpo - Seconda edizione riveduta e aggiornata

2022

Il volume affronta il tema del ruolo della volontà individuale nelle decisioni che riguardano, in senso ampio, il corpo umano. In particolare il principio di autodeterminazione, quale epifania del più ampio concetto di dignità personale, è posto a raffronto con le disposizioni in tema di trattamento sanitario - anche in riferimento alle prescrizioni anticipate di cura di cui alla l. n. 219/2017 - e con le scelte, assai complesse e dense di implicazioni sociali, sul termine della vita. La trattazione prosegue con l’esame della natura e della latitudine del consenso al prelievo di organi e tessuti da cadavere, per concludersi con l’analisi del ruolo della volontà nella procreazione, in quelle…

Phytochemical profile and insecticidal activity of Drimia pancration (Asparagaceae) against adults of Stegobium paniceum (Anobiidae)

2020

Chemical and spectroscopic investigation of the bulbs of Drimia pancration resulted in the isolation of one known flavonol (1), never isolated from this plant species, and of three previously described steroidal saponins (2–4), but whose configuration at their stereogenic centres was not clearly determined. By mean of 1H NMR, 13C NMR, nuclear overhauser effects (NOE) and two-dimensional NMR spectra the full stereochemical structures of compounds 2–4 were proved and all the 1H and 13C signals were assigned. Furthermore, the methanol and butanol extracts of D. pancration were tested against adults of Stegobium paniceum beetles. Despite the non-significant results regarding the repellent activ…

Furostanol saponins and ecdysones with cytotoxic activity from Helleborus bocconei ssp. intermedius

2009

Two furostanol saponins helleboroside A (1) and helleboroside B (2) were isolated from the methanol extract of Helleborus bocconei Ten. subsp. intermedius (Guss.) Greuter and Burdet, along with the furospirostanol saponin 4 and two ecdysones: ecdysterone (5) and polypodyne B (6). Compound 2 was enzymatically hydrolysed to give product 3. The biological activity of all compounds was tested against rat C6 glioma cells showing a significant cytotoxicity for compounds 3, 4 and 6. Copyright © 2009 John Wiley & Sons, Ltd.

PROFITABILITY OF SMALL LOQUAT FARMS IN SICILY

2015

The northern Sicilian coastline, known for its favorable soil and climatic conditions, represents the main production area in Italy for loquat (Eriobotrya japonica Lindl.). Over the years, the absence of process innovation and appropriate marketing strategies caused a gradual decline of loquat cultivation. This study estimates the profitability of some representative Sicilian farms that grow loquat in the area of Trabia (Palermo Province), where this crop is important for the local economy. The results highlighted a productive scenario characterized by high production costs, where only a family farm that supplies much of its own labor can survive.

Microspore Culture in eleven Cultivars of Loquat

2015

In plant breeding, microspore embryogenesis via isolated microspore culture is increasing as a method to obtain in a single-step doubled haploids and homozygosity. In this study, isolated microspore culture of eleven cultivars of loquat (Eriobotrya japonica (Thunb.) Lindl.) has been carried out. An analysis of anthers from different flower bud sizes, has been carried out, to identify and to select the flower bud size with anthers containing the highest quantity of vacuolated microspores. After a pre-treatment of the panicles at 4°C in dark for 4 days, flower buds were sterilized and microspores were isolated and cultured in two different media (P and MB). Moreover, only the isolated microsp…

Anaerobic membrane bioreactors for resource recovery from municipal wastewater: a comprehensive review of recent advances

2021

[EN] In a paradigm shift towards a sustainable society based on the Circular Economy, wastewater treatments are rapidly evolving towards simultaneous recovery and reuse of clean water, renewable energy, and nutrients. This review examines recent advances (from 2016 to 2020) in the potential of anaerobic membrane bioreactors (AnMBRs) to serve as the core technology for municipal wastewater (MWW) resource recovery, focusing on the latest technological advances and economic and environmental innovation perspectives. The potentials and limitations of AnMBR for further full-scale application and new platforms to address these challenges are discussed, covering systems based on co-digestion, pre-…

Levels, fingerprint and daily intake of polycyclic aromatic hydrocarbons (PAHs) in bread baked using wood as fuel

2009

Concentrations, fingerprint and daily intake of 16 PAHs in 15 bread samples baked using wood as fuel are examined in this work. Analysis was performed by GC/MS after saponification of the samples and clean up of the extract. The total concentration of the 16 analytes varies from 6 to 230 microg/kg on dry weight (d.w.). The better extraction procedure was estimated by analyzing test-samples and using different extraction methods. Additionally, for every analyzed sample, the extraction yield has been determined by the use of surrogate standards. Extraction yields were never less than 77% and in most cases almost 100%. The profiles of PAHs (percentage) are similar for all the analyzed samples …

Maximising resource recovery from wastewater grown microalgae and primary sludge in an anaerobic membrane co-digestion pilot plant coupled to a compo…

2021

[EN] A pilot-scale microalgae (Chlorella spp.) and primary sludge anaerobic co-digestion (ACoD) plant was run for one year in an anaerobic membrane bioreactor (AnMBR) at 35 °C, 70 d solids retention time and 30 d hydraulic retention time, showing high stability in terms of pH and VFA concentration. The plant achieved a high degree of microalgae and primary sludge substrate degradation, resulting in a methane yield of 370 mLCH4·gVSinf¿1. Nutrient-rich effluent streams (685 mgN·L¿1 and 145 mgP·L¿1 in digestate and 395 mgNH4-N·L¿1 and 37 mgPO4-P·L¿1 in permeate) were obtained, allowing posterior nutrient recovery. Ammonium was recovered from the permeate as ammonia sulphate through a hydrophob…
