Impacts of the covid-19 lockdown measures on the 2020 columnar and surface air pollution parameters over south-eastern Italy
No full textThe combined use of Lecce-University AERONET-photometer measurements and PM2.5, PM10, NO2, CO, and SO2 concentrations from different sites of Apulia-Region Air-Quality Agency represents the peculiarity of this study, which evaluates the impact of COVID-19 lockdown (LD) measures on aerosol and gaseous pollutants. Monthly-averaged columnar and surface parameters of the 2020-year were compared with corresponding monthly parameters of the ref-year obtained by averaging 2017, 2018, and 2019 measurements in order to evaluate LD measure impacts by Average Percent Departure (APD%). Photometer measurements showed that LD measures were likely responsible for the decrease in Aerosol Optical Depth (AOD). The APD% estimated between the 2020-and ref-year AOD (at 440 nm) was characterized by negative values from June to August, reaching the smallest mean value (−46%) in June. Moreover, the columnar aerosol load appeared less affected by continental urban/industrial particles than previous years in the summer of 2020. The PM-concentration-APD% calculated at ten sites was characterized by monthly trends similar to those of AOD-APD%. PM-APD% values varied from site to site and smaller values (up to −57% in June) were on average detected at urban/suburban sites than at background sites (up to −37%). The impact of LD measures on gaseous pollutants was observed from the onset of LD

No full textIl volume presenta l’intervento di restauro e rifunzionalizzazione con ampliamento dell’ex convento dei Frati Minori Osservanti, destinato a sede della Procura della Repubblica di Catanzaro. Commissionata dall’Agenzia del Demanio in sinergia con partner istituzionali quali il Comune, la Soprintendenza e la Procura, quest’ultima anche come ente usuario, l’opera è stata realizzata da un team di professionisti, coordinati dallo studio CORVINO + MULTARI, responsabili di tutte le fasi di progettazione, esecuzione, direzione lavori, direzioni artistica, strutturale, impiantistica e delle opere di restauro. Il progetto ha contemperato la tutela e la valorizzazione di un bene storico sottoposto a vincolo – l’ex convento risalente al XV secolo – con i requisiti richiesti dalla nuova destinazione d’uso, inscrivendo l’intervento in una più generale strategia di trasformazione dell’area su cui insiste il complesso. Il volume analizza questa opera pubblica in quanto esemplare delle opportunità di riqualificazione urbana che "costruire nella città" offre

No full textAnticancer potential of allicin: A review
No full textPhytochemicals have attracted attention in the oncological field because they are biologically friendly and have relevant pharmacological activities. Thanks to the intense and unique spicy aroma, garlic is one of the most used plants for cooking. Its consumption is correlated to health beneficial effects towards several chronic diseases, such as cancer, mainly attributable to allicin, a bioactive sulfur compound stored in different plant parts in a precursor form. The objective of this review is to present and critically discuss the chemistry and biosynthesis of allicin, its pharmacokinetic profile, its anticancer mechanisms and molecular targets, and its selectivity towards tumor cells. The research carried out so far revealed that allicin suppresses the growth of different types of tumors. In particular, it targets many signaling pathways associated with cancer development. Future research directions are also outlined to further characterize this promising natural product
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
