A survey on knowledge and self-reported formula handling practices of parents and child care workers in Palermo, Italy
2009
AbstractBackgroundPowdered infant formula (PIF) is not a sterile product, but this information appears to be poorly diffused among child caregivers. Parents and child care workers may behave in an unsafe manner when handling PIF.MethodsThis study involved parents and child care workers in the 24 municipal child care centres of Palermo. Knowledge and self-reported practices about PIF handling were investigated by a structured questionnaire. A Likert scale was used to measure the strength of the respondent's feelings. Association of knowledge and self-reported practices with demographic variables was also evaluated.Results42.4% of parents and 71.0% of child care workers filled in the question…
The invasive seaweed Asparagopsis taxiformis erodes the habitat structure and biodiversity of native algal forests in the Mediterranean Sea
2021
Abstract Invasive seaweeds are listed among the most relevant threats to marine ecosystems worldwide. Biodiversity hotspots, such as the Mediterranean Sea, are facing multiple invasions and are expected to be severely affected by the introduction of new non-native seaweeds in the near future. In this study, we evaluated the consequences of the shift from the native Ericaria brachycarpa to the invasive Asparagopsis taxiformis habitat on the shallow rocky shores of Favignana Island (Egadi Islands, MPA, Sicily, Italy). We compared algal biomass and species composition and structure of the associated epifaunal assemblages in homogenous and mixed stands of E. brachycarpa and A. taxiformis. The r…
Study of the implementation of SPIF as a Reshaping strategy in terms of formability and accuracy performance
2022
The adaption of circular economy strategies has become increasingly necessary in current times. Researches need to be addressed on finding alternative processes or the modification of the existing processes in order to reprocess End-of-Life (EoL) components and consequently recover both materials and their functions. This research paper focuses on the use of single point incremental forming (SPIF) process for the Reshaping of sheet metal EoL components. Uniaxial and biaxial pre-straining was performed on AA5754 sheets to imitate an end-of-life component, and SPIF operations were carried out so as to obtain reshaped components. In previous works, the authors have proven the technical feasibi…
Typification of the Linnaean name Centaurea seridis (Asteraceae)
2014
The genus Centaurea Linnaeus (1753: 909) (Asteraceae) comprises a large number of taxa mainly occurring in the Mediterranean region and southwest Asia (Susanna & Garcia-Jacas 2007). Centaurea seridis Linnaeus (1753: 915) is distributed from south Europe (Spain incl. Balearic Islands, Italy incl. Sicily, France, Albania and Greece) to northwest Africa (Algeria, Morocco and Tunisia). From a nomenclatural standpoint, Centaurea seridis has not been typified (Jarvis 2007: 402). This paper proposes the designation of a lectotype for this Linnaean name, based on the analysis of the protologue and original material.

Diatom species composition and indices for determining the ecological status of coastal Mediterranean Spanish lakes
2013
Diatom indices have been used and tested mainly for assessing the ecological status of rivers and deep lakes, but there are scarce studies that determine their effectiveness in shallow lakes and in coastal Mediterranean lakes. This study evaluates the validity of several common diatom indices (SPI, BDI, CEC and TDIL) for the determination of the ecological quality of three coastal lakes (Valencia, Spain) and presents descriptions and ecological data of the main diatom species recorded. Diatom samples were collected from phytobenthos, both from epiphyton of the dominant submerged macrophytes and the sediment. The ecological status of the systems was determined according to different physico-…
Contribution to the identification of Dianthus rupicola (Caryophyllaceae) subspecies using morphological and molecular approaches
2017
The systematic relationships between the five different subspecies actually recognized within Dianthus rupicola (subsp. aeolicus , subsp. bocchorianus , subsp. hermaensis, subsp. lopadusanus and subsp. rupicola ), were assessed by means of morphometric and molecular analysis. Our results highlighted the molecular differences between the five subspecies of D. rupicola and a morphological differentiation of four groups being D. rupicola subsp. aeolicus and D. rupicola subsp. rupicola partly overlapping. At the present state of knowledge, a subspecific status seems the most appropriate for all the recognized subspecies of D. rupicola . The names D. aeolicus , D. bisignanii var. virescens , D. …
Microbial Food Web Components as Potential Indicators of Urban Hydroecosystems / Mikrobiālās ķēdēs Komponentu Potenciāls Pielietojums Urbānās Vides Ū…
2015
Abstract Assessment of the effect of urbanisation on biodiversity and ecological impact studies are focused on plants, birds, terrestrial arthropods, and relatively few studies have been on aquatic organisms. The aim of this study was to investigate the microbial food web components as potential indicators of the trophic state of two small natural lakes (Gaiļezers, Bābelītis), two artificial lakes or reservoirs (created after excavation activities before 20 years) and the Gulf of Riga seaside Vecāķi beach (littoral), all of which are located in the city of Riga or close to it. Analysis of samples was conducted from April til October 2014 by epifluorescense microscopy for pico and nanoplankt…
Typification of the name Lavatera agrigentina (Malvaceae)
2019
As part of an ongoing study on the names of vascular plants described from Sicily (Southern Italy), a nomenclature investigation on the name Lavatera agrigentina Tineo, basionym of Malva agrigentina (Tineo) Soldano, Banfi & Galasso in Banfi et al., which appears to be yet untypified, is here presented.
