Microplastics ingestion by the exotic fish Gambusia holbrooki in two Mediterranean coastal lagoons
2020
Gambusia holbrooki es un pequeño pez Poecílido, de origen norteamericano que fue introducido a principios del siglo XX en humedales de la Península Ibérica para el control biológico de los mosquitos. Actualmente presenta poblaciones en muchos humedales y está considerada como una de las principales especies invasoras en la península. Estos peces se alimentan principalmente de invertebrados, pero son también susceptibles de ingerir y acumular residuos de microplásticos que presentan tamaños similares al tamaño de algunas de sus presas habituales. En el presente estudio analizamos los contenidos del tracto gastrointestinal de ejemplares adultos de esta especie, procedentes de dos lagunas cost…
Young managers’ drive to thrive: A personal work goal approach to burnout and work engagement
2009
This study approaches young managers’ occupational well-being through their work-related goal pursuit. The main aim was to identify content categories of personal work goals and investigate their associations with background factors, goal appraisals, burnout, and work engagement. The questionnaire data consisted of 747 young Finnish managers (23–35 years; M = 31 years) who were mostly men (85.5%). Seven work-related content categories were found on the basis of qualitative data analysis: (1) competence goals (30.5%), (2) progression goals (23.7%), (3) well-being goals (15.2%), (4) job change goals (13.7%), (5) job security goals (7.4%), (6) organizational goals (5.6%), and (7) financial goa…
Model Analysis of Hydrometeor Scattering Effects on Free Space Near-Infrared Links
2012
A promising technology for peer-to-peer connections and urban area networks is represented by wireless communications through free space using optical carrier (Free Space Optics, FSO). This technology ensures high data rates, with relatively low error rates, low power consumption and inherent security. Nevertheless FSO links are quite sensitive to atmospheric condition. Fog droplets, but also raindrops and snowflakes, may introduce severe path attenuation which drastically reduces the channel availability. A parametric model to simulate droplets scattering effects over the FSO link in terms of extinction coefficient, albedo factor and asymmetry coefficient as function of the particle water …

Gas chromatography-mass spectrometry study of polycyclic aromatic hydrocarbons in grass and milk from urban and rural farms
2000
Polycyclic aromatic hydrocarbon (PAH) levels were studied in grass and milk sampled at two farms, one located in a non-contaminated, rural area, and another located in a urban area close to PAH sources such as highways, busy roads, fuel-powered trains and a steel plant. PAH concentration were measured by gas chromatography coupled to mass spectrometry (GC-MS) using internal deuterated standards. In grasses, unexpectedly, although the sum of PAH concentrations was only slightly higher at the urban farm (83.1 ± 16.1 ng g−1) than the rural farm (51.8 ± 10.6 ng g−1), this difference was not observed for all PAH members. This absence of a striking difference of PAH levels between urban and rura…
The Use of Opuntia ficus-indica Mucilage and Aloe arborescens as Edible Coatings to Improve the Physical, Chemical, and Microbiological Properties of…
2022
Edible coatings (EC) with mucilage of Opuntia ficus-indica or Aloe arborescens are promising to extend the shelf life of fresh-cut fruit products by reducing weight loss and microbial spoilage. In this work, fresh-cut kiwifruits (cv. Hayward) were coated in solutions with mucilage extracted from Opuntia ficus-indica (MC) and A. arborescens (AL). We used three alternative treatments with AL or MC, MC+AL, and with distilled water as control, and stored in passive atmosphere at 5 °C for 3, 5, 7, and 9 d, respectively. For all treatments at each storage period, firmness, weight loss, color, visual quality score, respiration rate, pectin content, and microbiological characteristics were observed…
Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento
2019
Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…
The contents of collective bargaining in private sector in Italy
2020
The article analyzes the problem of the contents of collective bargaining in the private sector in Italy. In particular, after having dealt with the issue of the freedom to identify the content of the collective agreement, it distinguishes between the normative and the obligatory part of it, and examines the relationship between law and collective agreement.
