Changing people’s attitudes and beliefs toward driving through floodwaters : Evaluation of a video infographic
2018
Despite awareness of campaigns such as ‘Turn Around, Don’t Drown’ and the Australian state of Queensland’s ‘If It’s Flooded, Forget It’, people continue to drive through floodwaters, causing loss of life, risk to rescuers, and damage to vehicles. The aim of this study was to develop a video infographic that highlights the dangers of driving through floodwaters and provide safety tips to reduce the risk, and to evaluate its effectiveness in changing the beliefs and intentions of Australian adults toward this risky driving behaviour. This study adopted an online three-wave non-controlled pretest–posttest design. Australian licensed drivers (N = 201, male = 41, female = 160; Mage = 34.10) self…
Levels and Potential Health Hazards of Chlorinated Pesticidesin Surface Water Samples of Charsadda Area of Pakistan Using SPME-GC-ECD Technique
2021
In the present study, we determined the levels of chlorinated pesticide residues in surface water samples collected from the Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis of 20 organochlorine pesticides in the collected water samples. For maximum efficiency of the SPME procedure, several parameters were studied, including the extraction and desorption time of the fiber, solution pH, agitation of samples, and stirring speed, etc. This method showed good liner response, with R2 values in the range of 0.9887 to 0.9999 for all pesticides. This method also provided good percent recoveries at 1 µg L−1 (87.5 to 106.0%) and at 2 …
Transformations Accompanying a Shift from Surface to Drip Irrigation in the Cànyoles Watershed, Valencia, Spain
2017
Drip irrigation is widely promoted in Spain to increase agricultural production and to save water. In the Cànyoles watershed, Valencia, we analysed the consequences of change from surface irrigation to drip irrigation over the past 25 years. There were a number of transformations resulting from, or accelerated by, this change including the 1) intensification of well construction causing a redistribution in access to groundwater, water shortages and a lowering of the groundwater table; 2) expansion of irrigation into former rain-dependent uphill areas resulting in increased water use; 3) shift to higher- value monoculture fruit crops, but with associated higher crop water requirements; 4) in…
Diallyldimethylammonium Chloride (DADMAC) in Water Treated with Poly-Diallyldimethylammonium Chloride (PDADMAC) by Reversed-Phase Ion-Pair Chromatogr…
2023
Poly-diallyldimethylammonium (PDADMAC) chloride is a flocculant agent extensively used in water clarification treatments. Commercial polyelectrolyte formulations often contain residual monomer (DADMAC), reaction by-products and other reactants as contaminants that could potentially affect human health. In the present study, we optimized an analytical method based on reversed-phase ion-pair chromatography coupled with mass spectrometry for quantifying ultra-trace levels of DADMAC, without preliminary treatments, in drinking water distributed by the Palermo aqueduct. The method was validated in terms of accuracy (recovery between 80 to 120%), precision (RSD < 10%), linearity range (from 0.…
Il progetto per il waterfront centrale di Palermo ed il nuovo Piano Regolatore Portuale
2011
Potenti “commutatori territoriali”, i waterfront urbani sono dispositivi in grado di intercettare e trasferire al contesto urbano in cui si inseriscono le energie materiali e immateriali che le grandi reti infrastrutturali di cui sono terminali veicolano, traducendole in risorse ed economie territoriali. In base a questa idea-guida la rigenerazione del waterfront di Palermo, parte di un più ampio programma innovativo “Porti&Stazioni”, finanziato dal Ministero delle Infrastrutture, trova nel nuovo Piano regolatore portuale uno strumento capace di integrare e facilitare entro un quadro di coerenza generale le riflessioni e le visioni progettuali sul rapporto tra la città ed il suo mare.
La progettazione di interventi per il benessere individuale e di comunità
2022
I progetti di intervento in ambito sociale e psicologico prevedono azioni volte a creare una rete non solo tra istituzioni e supporto informale, ma anche un'opportunità di cambiamento per i beneficiari. In tal senso, nel 2020, 6 giovani dei Servizi della Giustizia Minorile di Palermo hanno par-tecipato ad un progetto ottenendo un'opportunità di cambiamento attraverso la promozione del benessere, sia come individui sia come membri di una comunità. In generale, tali interventi consistono nel sostenere le categorie sociali e gli individui più vulnerabili. L'adozione dello sport acquatico è una metodologia valida, poiché si basa sulla condivisione di norme oltre che sulla responsabilità individ…
