Environmental hazard and water quality: the River Platani basin

2007

The River Platani, situated in the western side of Sicily, is one of the greatest rivers of the island. It runs for about 103 Km and the basin extends to about 1,784.9 Km. It rises near Santo Stefano Quisquina (Ag); the river flows to Capo Bianco (Ag) ends in the Mediterranean Sea. The morphology of the basin is predominantly characterized by rises of modest entities with slopes sweet or calanques. In the containing gypsum and carbonatic stony heaps are diffused the karst phenomena. In the Platani basin some mines are located of rock salt and potassium salts; today the mines are closed after a long activity and they interact with the geomorphology of the territory and on the water quality o…

Country Life Quality in the Opinion of Young People in Respect of Their First Job Location Decision – Subjective Approach

2017

Mimo poprawy infrastruktury w wielu obszarach wiejskich można zauważyć niekorzystne tendencje związane zarówno z przyrostem naturalnym, starzeniem się społeczeństwa, jak i ujemnym saldem migracyjnym. W kraju takie tendencje są najbardziej widoczne na obszarach wschodnich (Podkarpacie, Podlasie) oraz zachodnich (Opolszczyzna). W artykule podjęto próbę oceny jakości życia na obszarze wiejskim przez ludzi młodych i poznania ich preferencji co do miejsca studiowania i podjęcia pracy czy też prowadzenia działalności gospodarczej w okresie rozpoczynania aktywności zawodowej. Jako próbę badawczą wybrano uczniów szkoły średniej mieszkających i uczących się na obszarze wiejskim w szkole oferującej k…

A sustainable city environment through child safety and mobility:A challenge based on ITS?

2012

Our cities should be designed to accommodate everybody, including children. We will not move toward a more sustainable society unless we accept that children are people with transportation needs, and ‘bussing’ them around, or providing parental limousine services at all times, will not lead to sustainability. Rather, we will need to make our cities walkable for children, at least those above a certain age. Safety has two main aspects, traffic safety and personal safety (risk of assault). Besides being safe, children will also need an urban environment with reasonable mobility, where they themselves can reach destinations with reasonable effort; else they will still need to be driven. This p…

Spatial data fusion and analysis for soil characterization: a case study in a coastal basin of south-western Sicily (southern Italy)

2012

Salinization is one of the most serious problems confronting sustainable agriculture in semi-arid and arid regions. Accurate mapping of soil salinization and the associated risk represent a fundamental step in planning agricultural and remediation activities. Geostatistical analysis is very useful for soil quality assessment because it makes it possible to determine the spatial relationships between selected variables and to produce synthetic maps of spatial variation. The main objective of this paper was to map the soil salinization risk in the Delia-Nivolelli alluvial basin (south-western Sicily, southern Italy), using multivariate geostatistical techniques and a set of topographical, phy…

Dispersal ecology of deadwood organisms and connectivity conservation

2018

Limited knowledge of dispersal for most organisms hampers effective connectivity conservation in fragmented landscapes. In forest ecosystems, deadwood‐dependent organisms (i.e., saproxylics) are negatively affected by forest management and degradation globally. We reviewed empirically established dispersal ecology of saproxylic insects and fungi. We focused on direct studies (e.g., mark‐recapture, radiotelemetry), field experiments, and population genetic analyses. We found 2 somewhat opposite results. Based on direct methods and experiments, dispersal is limited to within a few kilometers, whereas genetic studies showed little genetic structure over tens of kilometers, which indicates long…

Science education and the “state of the world”: a programme of activities to enhance teacher’s perception of global problems and possible remedies

2003

A literatura sobre formação de professores de ciências não tem tratado suficientemente a situação do mundo quanto a uma percepção global de seus graves problemas atuais. O presente artigo consiste essencialmente de um programa de atividades a ser desenvolvido com professores em formação e em exercício, que visa favorecer uma reflexão coletiva e conscientização sobre essa problemática. Nesta perspectiva é apontado um conjunto de referências e questões para um debate fundamentado sobre vários dos fatores associados à degradação da vida e sobre possíveis medidas para o enfrentamento da emergência planetária. Investigações preliminares sobre a utilização do programa proposto têm revelado result…

Effect of different packaging methods on the free amino acid profiles of the deep-water rose shrimp (Parapenaeus longirostris) during frozen storage

2022

The composition of free amino acids (FAAs) in seafood products contributes to characterizing their flavor, as well as freshness and quality during storage. Deep-water rose shrimps (Parapenaues longirostris, Lucas, 1846) (DWRS) are being increasingly harvested in the Mediterranean Sea, and the captured specimens are quickly frozen onboard fishing trawlers to preserve freshness and post-harvest quality. Here, we quantified the FAA profiles of DWRS packaged using five methods: (1) 100% N2; (2) vacuum; (3) 50% N2 + 50% CO2; (4) commercial anhydrous sodium sulfite; and (5) air (control). All samples were quickly frozen at −35°C and stored for 12 months at −18°C. Arginine (661 mg/100 g), proline …

The early careers of the second generations: a double ethnic penalty?

2016

International audience; Young people from North African origin have greater difficulty in finding employment than their counterparts of French origin. And once they do manage to find employment, their jobs tend to be of lower quality. Thus they appear to suffer from a double penalty linked to their origins which, aggravated by the crisis, does not seem to abate over time.
