Desenvolupament de línies experimentals per a la seva aplicació en els Treballs de finalització de Grau en Química
2012
Des del punt de vista acadèmic, els Treballs Fi de Grau en Ciències Químiques es presenten com a projectes experimentals relacionats amb problemes reals, orientats a progressar en coneixements i enfortir competències adquirides, convertint-se en claus del currículum per al món professional. S’aborden una sèrie de projectes integrals de laboratori com una aproximació més realista a l’aprenentatge integral. La metodologia docent proposta afavoreix la busca d’informació, pensament crític, superació contínua i èxit dels estudiants, semblant a la què es realitza en el món real, estimulant el seu interès i motivació durant el procés d’aprenentatge.
CARATTERIZZAZIONE METAGENOMICA di MICRORGANISMI E ORGANISMI DEL TERRENO PER UN LORO UTILIZZO COME AGENTI di LOTTA BIOLOGICA CONTRO NEMATODI FITOPARAS…
2014
La microflora della rizosfera riveste un ruolo fondamentale sia nella difesa che nello sviluppo e crescita delle piante. Molti studi hanno dimostrato inoltre che i nematodi sono in grado d’influenzarne la composizione. I batteri a loro volta producono una varietà di composti (antibiotici, nutrienti, esoenzimi e altre molecole segnale), in grado d’indurre ulteriori cambiamenti. L’obiettivo di questo lavoro è stato quello di studiare i cambiamenti nella biodiversità della microflora batterica di un terreno proveniente da un’azienda biologica, conseguenti all'introduzione sperimentale di larve di Meloidogyne incognita e al trattamento con un nematocida (fenamifos). Seguendo un approccio metage…
Amino polyphosphonates - chemical features and practical uses, environmental durability and biodegradation
2012
Growing concerns about the quality of the environment led to the introduction of complex system of safety assessment of synthetically manufactured and commonly applied chemicals. Sometimes, however, our knowledge of consequences that result from the usage of these substances, appears far later, than at the beginning of their application. Such situation is observed in the case of aminopolyphosphonates being an important subgroup of organophosphorus compounds. The increasing industrial and household applications, led to introduce thousand tons of polyphosphonates every year into the environment. These substances are difficult to determine in environmental samples because of lack of appropriat…
Bacterial Community Structure of an IFAS-MBRs Wastewater Treatment Plant
2017
TIn this work, the bacterial community putatively involved in BNR events of a UCT-MBMBR pilot plant was elucidated by both culture-dependent and metagenomics DNA analyses. The presence of bacterial isolates belonging to Bacillus (in the anoxic compartment) and to Acinetobacter, Stenotrophomonas, Rhodococcus, Escherichia and Aeromonas (in the aerobic compartment) is in agreement with the nitrification/denitrification processes observed in the plant. Moreover, the study of bacterial community structure by NGS revealed a microbial diversity suggesting a biochemical complexity which can be further explored and exploited to improve UCT-MBMBR plant performance.
Proposals for improvement of Annex I of Directive 92/43/ EEC: Central Italy
2021
The main purpose of the 92/43/EEC Habitats Directive is to contribute to the conservation of biodiversity, understood as habitat types and species of the flora and fauna of the European Union. To achieve this goal, natural and semi-natural biodiversity as a whole must be recognized and included in its annexes. As for the conservation of biotopes, named habitat types, Italy is unfortunately lacking as it the Annex I does not include important ecosystems that are typical of its territory, rare for biogeographical reasons or threatened. Therefore, the opportunity to identify a first list of significant habitats for central Italy is discussed here. For each of the new proposed types (new habita…
Typification of the name Statice calcarae (Plumbaginaceae), basionym of the threatened endemic Limonium calcarae
2018
Limonium calcarae (basionym Statice calcarae), a rare diploid species endemic to Sicily, is one of the few members of the genus that occurs in the inland areas of the island. According to IUCN criteria, it has been assessed as critically endangered but recent data on its distribution, demography and threats affecting its populations are lacking. A lectotype is designated, preserved at PAL, and isolectotypes have been traced and verified in other European herbaria.

Electron delocalization in mixed-valence Keggin polyoxometalates. Ab initio calculation of the local effective transfer integrals and its consequence…
2002
We present a quantitative evaluation of the influence of the electron transfer on the magnetic properties of mixed-valence polyoxometalates reduced by two electrons. For that purpose, we extract from valence-spectroscopy ab initio calculations on embedded fragments the value of the transfer integrals between W nearest-neighbor atoms in a mixed-valence alphaPW(12)O(40) polyoxowolframate Keggin anion. In contradiction with what is usually assumed, we show that the electron transfer between edge-sharing and corner-sharing WO(6) octahedra have very close values. Considering fragments of various ranges, we analyze the accuracy of calculations on fragments based on only two WO(5) pyramids which s…
Contribution to the knowledge of Inonotus baumii in Thailand
2015
Inonotus baumii in Thailand is reported on three new host-plants: Acacia tomentosa, Shorea robusta, and S. siamensis. A key for the identification of Inonotus species in Thailand accompanies notes on the taxonomy of I. baumii.
The role of sport-specific play and practice during childhood in the development of adolescent Finnish team sport athletes
2016
This study sought to understand the role of sport-specific play and practice in the development of adolescent team sport athletes in the Finnish sports development system. Participants were male, 15-year-old soccer (n = 141), ice hockey (n = 204), and basketball (n = 96) players, divided into three groups based on the amount of sport-specific play and practice experienced during childhood. Data were collected with sport-specific inventories of practice history, tactical skills, psychological skills, and sport-specific skill test. Results showed that athletes with more sport-specific play and practice during childhood had more sport-specific play and practice during adolescence, better techn…
