The Averinga’s Edicola and the Cult of Water in Palermo. From Knowledge to Valorisation

2018

Si descrive un approccio multidisciplinare allo studio di un singolare monumento storico, l’Edicola dell’Averinga, che versa attualmente in gravi condizioni di degrado; questa costruzione fu realizzata nel 1587 dal Senato Palermitano a protezione delle acque della sorgente Ayn Rutah (nome arabo di Averinga) che sgorgavano proprio al suo interno e che da qui venivano raccolte e incanalate verso i fertili giardini, le abitazioni che si trovavano in prossimità delle mura cittadine e alcune delle più importanti fontane della città storica. La più antica descrizione a noi pervenuta della zona in cui è sita l'Edicola, la cosiddetta depressione Danisinni, appartiene al geografo iracheno Al-Qaim Mu…

Antioxidant capacity of infant fruit beverages: influence of storage and in vitro gastrointestinal digestion

2008

Reyes.Barbera@uv.es; M.J.Lagarda@uv.es; Rosaura.Farre@uv.es The total antioxidant capacity of three beverages based on fruit juice, milk and cereals, intended for infants and young children up to 3 years of age was evaluated by two methods Trolox Equivalent Antioxidant Capacity and Oxygen Radical Absorption Capacity. Results: According to the total antioxidant values obtained by both methods, the beverages can be ranked as follows: grape-orange-banana > peach-apple > pineapple-banana. Ascorbic acid was the main contributor (60%) to the total antioxidant capacity, while the contribution of skimmed milk was less than 1.2%. After one month of storage at -20 ºC, significant losses (p < 0.05) in…

Inhibition of aflatoxin B1, B2, G1 and G2 production by Aspergillus parasiticus in nuts using yellow and oriental mustard flours

2015

Abstract Aflatoxins (AFs) are naturally occurring mycotoxin compounds produced by several species of Aspergillus, as Aspergillus flavus and Aspergillus parasiticus and are mutagenic, teratogenic, and carcinogenic compounds that have been implicated as causative agents in human hepatic and extra hepatic carcinogenesis. In this study, the reduction of the AFs present in dried fruits (peanut, cashew, walnut, almond, hazelnut and pistachio), produced by A. parasiticus CECT 2681, by isothiocyanates (ITCs) generated by the enzymatic hydrolysis of the glucosinolates (GLCs) present in oriental and yellow mustard flours was evaluated. The AFs reduction activity through ITCs application in dried frui…

Indagini sulla presenza di Prays oleae in oliveti a conduzione biologica della Sicilia occidentale

2011

Investigations on presence of Prays oleae in organic olive orchards of western Sicily. This paper reports a study on the population dynamics of the olive moth, Prays oleae (Bern) (Lep., Plutellidae) in four organic olive orchards in western Sicily (Italy), from 2007 to 2010. The influence of the phytophagous on the fruit drop was detected. Also, the efficacy of treatments with Bacillus thuringiensis var. kurstaki on damage reduction was evaluated. Flight trend was monitored using delta-wing traps (3/ha) containing the sexual pheromone ((Z)-7-tetradecenal), placed in each olive orchard. Traps were hung in the inner zone of the canopy to a height of 1.50 m, and checked weekly from May to 2-3 …

OLIVE FRUIT FLY: A threat to the South African olive industry?

2015

Olive fruit fly (Bactrocera oleae) is the most serious pest of cultivated olives in the Mediterranean basin. to date we have not seen the same level of damage in south africa, but the question remained whether it poses a similar threat as the local olive industry expands. From this study it is clear that the climatic con- ditions during the period preceding harvest are un- favourable for rapid population growth of OFF in the Western Cape, in contrast to conditions in the coastal area of Trapani province in Sicily. Climate, and not parasitism, appears to be the main factor limiting OFF population levels in the Western Cape. While sporadic outbreaks of economically damaging OFF infestations c…

Non-Enzymatic Water-Soluble Antioxidants Bioanalysis in Some Teas and Juices by PCL Method

2011

Non-enzymatic water-soluble antioxidants from different teas (black, green, peppermint), coffee, natural extract of rosemary and fruit juices (apple, grape, grapefruit, kiwifruit) were quantized by measuring their chemiluminescence in order to establish their power to protect the living beings from the free radicals. Among the samples high values of antioxidative capacity presents green tea (655 mmol AU) (AU=ascorbic units) and kiwi fruit juice (31 mmol AU). The maximum measuring times are less than 3 minutes. The sensivity of the photo-induced chemiluminescence (PCL) method was very high: nanomolar concentrations of non-enzymatic watwer-soluble antioxidative substances, as ascorbic acid un…

Organic residues in lake and drinking water from the lagoa de Juturnaíba (região dos lagos - RJ, Brazil)

1997

Various analytical methods for the determination of organic residues in water were applied to samples from the Lagoa de Juturnaíba in the Região dos Lagos, east of Rio de Janeiro. The concentrations of more than 60 pesticides and of different aminopolycarboxylic acids were determined using GC/MS detection, and a GC/MS screening procedure was applied to detect additional compounds. None of the investigated pesticide residues could be detected in the lake water at detection limits of less than 100 ng/L. EDTA was detected at a concentration level of 2 mg/L in the lake and in drinking water prepared from this lake. Traces of biphenyl were identified by GC/MS in the lake water, the source of whi…

The role of native flower visitors in pollinating Opuntia ficus-indica (L.) Mill., naturalized in Sicily

2011

Abstract The role of insects in pollination and consequently in fruit set and quality was assessed in two commercial orchards of the cactus pear, Opuntia ficus-indica (L.) Mill., in Agrigento Province, Sicily. In 1997, insects visiting flowers were sampled during May–June (the first bloom) and July (the second bloom, induced by the “scozzolatura” practise). More than 50 insect species belonging to 10 orders were collected in May–June, while only five species of Hymenoptera Apoidea were collected in July. The quality of fruits arising from the second bloom showed that Hymenoptera alone were able to guarantee effective pollination. To verify the role of insects in pollination in 1996 (during …
