Centromeric heterochromatin and satellite DNA in the Chironomus plumosus species group

1994

Species of the Chironomus plumosus group display significant differences in their amount of centromeric heterochromatin. A tandem-repetitive satellite-like DNA has been isolated from C. plumosus. This DNA accounts for a major part of the centromeric heterochromatin. The DNA element has a Sau3AI restriction site ("Sau elements") and a monomer length of 165 or 166 bp. It is A-T rich (73%) and reveals a moderate DNA curvature, as shown by gel migration and computer analysis. The chromosomal localization and genomic organization of Sau elements were studied in 24 Chironomus species by in situ hybridization and (or) Southern analysis. The DNA is predominantly located in the centromeric regions …

Quality indicators for modified atmosphere packaging (MAP) storage of high-quality European plum (Prunus domestica L.) cultivars.

2016

The use of quality indicators is crucial in selling plums in more distant markets and the evaluation of freshness through multiple index is fundamental to evaluate the goodness of the storage technique. In this study we evaluated the quality of two european plums cultivars ('Ramasin' and 'Ariddo di Core' with purple and yellow flesh colour respectively) after modified atmosphere packaging (MAP) storage, through the selection of the most appropriate indicators. The headspace gas composition, the flesh fruit firmness (FFF), the soluble solid content (SSC), the titratable acidity (TA), the colour and the chlorophyll content of plums wrapped with 5 different films (F1, F2, F3, F4 and F5) were e…

The effect of modified atmosphere packaging on the physical and chemical quality of fresh yellow plum cultivars

2013

The aim of this work was to store fresh yellow plums (cvs. Sanacore and Ariddo di Core) for a maximum of 20 days at 1°C±1 and 90–95% relative humidity (RH) using modified atmosphere (MA) technology (flowpack system). Fruits of both cultivars were sealed in baskets with six films and compared with fruit stored under a normal atmosphere (NA). The effect of several packaging materials and several gas concentrations in modified atmosphere packaging (MAP) were evaluated on the postharvest quality of plums considering the weight loss, flesh texture, total soluble solids (TSS) and titratable acidity (TA). Samples were monitored at 0, 5, 10, 15 and 20 days. All continuous plastic films used have ox…

Rootstock Evaluation for European and Japanese Plums in Italy

2012

The continuous update coming from fruit trees genetic improving projects determines constant innovations in terms of cultivars and rootstocks availability. In Italy, since 1995, the National Government has developed a research activity spread over the entire National territory. The project, which involves several Research Units, is related to all major fruit tree species and also plum regarding new Japanese and European cultivars as well as new rootstocks. The evaluation is performed by using the same experimental protocol, focusing on the vegetative and reproductive traits as well as on all aspects related to fruit quality. This paper shows data collected since the planting in 1995 from fe…

Primi studi sulla biologia e sul controllo di Cydia funebrana (Treitschke) in susineti biologici siciliani

2011

First studies on biology and control of Cydia funebrana (treitschke) in Sicilian organic plum orchards. Cydia funebrana (Treitschke), considered the key pest in the Sicilian plum orchards. Few studies were carried out in Sicily concerning C. funebrana life cycle, forecasting models and the effectiveness of some products permitted in organic plum orchards. In 2010 researches were carried out in three Sicilian plum orchards, two in Palermo Province (Monreale and San Giuseppe Jato) and one in Agrigento Province (Castrofilippo), in order to monitor the population, to evaluate damage levels caused by the plum moth and to estimate how many generations it could complete by Charmillot’s forecasting…

NEOTECTONIC ACTIVITY AND EMISSION OF FLUIDS IN THE NORTHWEST SICILY CHANNEL

The southern Sicilian coast represents an important contribution to Italian tourism, the Sicily Channel is an important communication path because at the top of its seafloor there are many pipelines, and submarine communication cables which are laid to carry signals, and which are very important to the minor islands. In this work, we are presenting results of the detailed geomorphological and seismostratigraphic analysis based on new very high-resolution dataset (multibeam and CHIRP) acquired during the ACUSCAL 2015 Cruise. We also used low resolution bathymetric and seismic data provided from online database (ViDEPI, GEBCO, EMODnet). This study allows us to reconstruct the tectonic volcani…

Lucio Piccolo. Mondo lirico

2006

Lo sconosciuto poeta Lucio Piccolo irrompe sulla scena letteraria italiana nel 1954, all’età di 51 anni, quando Eugenio Montale scopre quasi per caso i suoi Canti barocchi e decide di presentarli al convegno di San Pellegrino Terme. Il fascino musicale di quelle liriche piene di suggestioni letterarie e di immagini vivissime e la compagnia di un altro misterioso personaggio della colta nobiltà siciliana - il cugino Giuseppe Tomasi Principe di Lampedusa - conquistano immediatamente i più grandi scrittori e critici del momento. 
L’anziano ed eccentrico Cavaliere di Calanovella diventa all’improvviso un “caso” nazionale. Lucio Piccolo non si muove dalla campagna di Capo d’Orlando, nel messines…

Rapid chemical evolution of tropospheric volcanic emissions from Redoubt Volcano, Alaska, based on observations of ozone and halogen-containing gases

2013

Abstract We report results from an observational and modeling study of reactive chemistry in the tropospheric plume emitted by Redoubt Volcano, Alaska. Our measurements include the first observations of Br and I degassing from an Alaskan volcano, the first study of O 3 evolution in a volcanic plume, as well as the first detection of BrO in the plume of a passively degassing Alaskan volcano. This study also represents the first detailed spatially-resolved comparison of measured and modeled O 3 depletion in a volcanic plume. The composition of the plume was measured on June 20, 2010 using base-treated filter packs (for F, Cl, Br, I, and S) at the crater rim and by an instrumented fixed-wing a…

Origin and Evolution of High-Grade Gneiss Terrains

1990

In the previous chapters we have given an impression of the way in which the analysis of high-grade rocks can be approached in the field. Here we conclude with some current larger-scale ideas on the origin and evolution of such rock assemblages.
