Let’s Plan the School Garden: A Participatory Project on Sustainability in a Nursery School in Padua
No full textThe increasing complexity of urban regions and the lack of green areas in the neighborhoods have turned the cities less and less child-friendly. In order to locally face these situations, the project “Small steps of Agenda 21”, which promoted a participatory planning experience for children focused on the green area of their school, was realized in the nursery school “J. Mirò” in Padua.
During the project the children had the opportunity to be real protagonists of the improvement on the school garden while growing the awareness of the importance of discussion and participation in the local community. Results show that children improved their sense of inclusiveness and responsibility and prove that Agenda 21 processes are possible also in the nursery school

No full textInfluence of Cultivar and Cultural Practices on Chemical Composition of Tall Fescue Turf
No full textA field trial was carried out at the experimental farm of Padova University in order to evaluate the effect of cultivar and cultural practices (fertilization and mowing management) on some chemical characteristics of live tissues of tall fescue turf. At each season samples of verdure were taken after the cut and divided into live and dead parts to determine the dry weight of both components. Moreover, from live tissues was determined the content of: crude protein (CP), crude fiber (CF), NDF, ADF, ADL, ether extract (EE) and ash. Results showed that DM of vegetative tissues (g m-2) decreased during winter, while the DM of dead tissues reached the lowest values in spring. At the end of winter period (March), while the structural carbohydrates decreased the components of cell content (CP and EE) tended to increase. Treatment comparison showed a decrease of turf dead tissues in consequence of mowing height reduction as well as a depletion of wall cell components. Cultivar differences were ..

No full textSensorial, biochemical and molecular changes on Raboso Piave grape berries harvested by applying double reasoned maturation and late harvest techniques
No full textAt ripening Raboso Piave grapes are characterized by peculiar organoleptic traits, such as high acidity and astringency. Because of these characteristics, the consumption of the wine obtained from this cultivar is not widely diffused. To overcome this limitation, researches have been carried out for altering the polyphenols profile by mainly applying different harvest techniques. Aim of this work was to investigate sensorial, biochemical, and molecular changes occurred in Raboso Piave grape berries subjected to Late Harvest (LH) and Double Reasoned Maturation (DRM) techniques. Particular attention was paid to changes on the biosynthetic pathways of polyphenols, considering their influence on wine organoleptic and quality traits. As highlighted by the sensory analysis results, significant changes on polyphenols profile occurred in grape berries harvested by applying these techniques, but particularly when DRM was applied. In fact in DRM-grape berries, the flavonols and cathechin accumulation were induced and depressed, respectively. In parallel with these changes, the transcription of the Flavonol synthase and the accumulation of Leucoanthocyanidin-reductase mRNAs were induced and depressed, respectively. These modifications allow to maintain a brighter color as well as to reduce the level of astringency in the wine
A comparative transcriptomic approach to elucidate common and divergent mechanisms involved in apricot and peach fruit development and ripening
No full textTranscript profiling methods are increasingly used to understand the biological basis of growth and development, and fruit quality in the case of fruits. Such methods provide information for thousands of genes, including those of still unknown function. Furthermore, high-throughput methodologies can be used for comprehensive transcriptome analyses, which may lead to further elucidation of fruit growth and development. Microarray is an attractive genomic tool, since it can be used in a heterologous fashion for gene discovery and characterization in species where few resources are available. In the current study, the progress of apricot (Prunus armeniaca cv. Goldrich) fruit ripening during the last developmental stages was monitored and microarray data that were produced were used for comparative in silico studies with data reported during the transition of peach and nectarine fruits from pre-climacteric to climacteric stage. Transcriptomic studies for both fruit species were carried out using the first available peach microarray (μPEACH 1.0) that contains 4,806 oligonucleotides, each corresponding to a single unigene. Intriguingly, a sharp increase of transcript levels in genes regulating an array of heat shock proteins was detected in apricot fruit, which was not the case during nectarine fruit ripening. In addition, we focused on transcript levels of auxin regulated proteins and their role during the last phases of fruit ripening. Overall, data of the present study offers an initial descriptive picture of transcript profiling of novel key genes and their putative role during the last stages of fruit development is challenged. A future perspective, which will also encompass data validation for genes of interest, is the unravelling of the mechanisms underlying the ripening process in stone-fruits, through the identi¬fication of genes differentially expressed during peach and apricot ripening and their correlation with traits of agronomic interest
Il Dipartimento di Geografia come aula didattica
No full textNel sempre vivo tentativo di unire ricerca geografica e didattica, il Dipartimento di Geografia “G. Morandini” dell’Università di Padova ha lanciato, tramite il progetto del Comune “Vivipadova, un’aula grande come la tua città”, una modalità nuova di collegamento con il mondo della scuola.
“Vivipadova” è un programma di itinerari educativi per la scuola dell'obbligo, attivo dall'anno scolastico 1984/85, che collega, attraverso numerose proposte, il mondo scolastico ed extrascolastico. La città si trasforma in una grande aula di studio e di lavoro, dove gli alunni, guidati dai loro insegnanti, imparano a conoscerla, a esplorarla, ad apprenderne la struttura e l'organizzazione. All’interno di questa proposta il Dipartimento di Geografia ha offerto tre percorsi formativi nati allo scopo di collegare alcune riflessioni teoriche - la spazialità nel bambino, il rapporto tra geografia fisica e umana e la rappresentazione cartografica - con la didattica. Tutta la struttura si è messa in gioco con la consapevolezza che la divulgazione del sapere scientifico passa dai bambini in una sorta di orientamento precoce ai temi geografici.
Inizialmente il Comune aveva finanziato 14 percorsi. All’avvio delle iscrizioni via web, in poche ore, sono arrivate più di 90 richieste da parte delle scuole del solo Comune di Padova. Questo dato è stato letto come una richiesta di aiuto: la geografia nella scuola non è morta e gli insegnanti hanno bisogno di strumenti nuovi, di idee fresche, di consigli pratici che si pongono come vie per riscoprire nuovi modi di fare geografia.
Con un notevole sforzo siamo riusciti ad attivare 33 laboratori. A nessun Ente afferente al Progetto è stata data questa opportunità, evidente segno di fiducia nei confronti delle proposte suggerite.
