Natura e alterita: ancora sull'Aria del Tasso di Giuseppe Tartini:
2014
La passione di Giuseppe Tartini per la musica popolare è attestata da quattro versioni per violino dell’Aria del Tasso. L’Aria rientra nell’ambito di una nuova poetica che ricerca la verità nei canti di natura. Come i musicografi della generazione successiva, il violinista attribuisce alla semplicità un ruolo paradigmatico per separare il concetto di natura dal concetto di artificio. Per cui, il semplice canto di popolo, assieme alla musica greca del periodo classico e alla musica delle «nazioni» non evolute, è più vicino allo stato primigenio, ossia allo stato di natura e quindi alla verità. A questo problema si collegano tre fasi del pensiero del trattatista, in cui il termine natura subi…
Microbial and chemical origins of the bactericidal activity of thermally treated yellow mustard powder toward Escherichia coli O157:H7 during dry sau…
2010
Abstract Work examines the origin of bactericidal activity in mustard flour and explores the relative contribution from starter cultures, E. coli O157:H7 itself and other sources. Bacteria can degrade naturally occurring glucosinolates in mustard and form isothiocyanates with antimicrobial activity. In the present work, 24 starter cultures (mostly from commercial mixtures) were screened for their capacity to decompose the glucosinolate, sinalbin. The most active pair, Pediococcus pentosaceus UM 121P and Staphylococcus carnosus UM 123M, were used together for the production of dry fermented sausage contaminated with E. coli O157:H7 (~ 6.5 log CFU/g). They were compared to industrial starters…
Development of "Quadrello di Ovino", a Novel Fresh Ewe's Cheese.
2021
This work was performed to produce a new soft ewe’s milk cheese, namely “Quadrello di ovino” (QdO) cheese, to enlarge ewe’s dairy product portfolio of South Italy, barely limited to Pecorino cheese typology. Cheese making was performed applying the technology for “Crescenza” cheese typology with some modifications. In particular, pasteurized ewes’ milk was inoculated with two commercial starter formulations (SF1 and SF2) of Streptococcus thermophilus to obtain two different productions (QdO-P1 and QdO-P2, respectively). Plate counts demonstrated the ability of both starter formulations to drive the fermentation process, since S. thermophilus counts reached 109 CFU/g in both productions. Gen…
THE EFFECT OF GADOLINIUM ON THE ESR RESPONSE OF ALANINE AND AMMONIUM TARTRATE EXPOSED TO THERMAL NEUTRONS
2008
Many efforts have been made to develop neutron capture therapy (NCT) for cancer treatment. Among the challenges in using NCT is the characterization of the features of the mixed radiation field and of its components. In this study, we examined the enhancement of the ESR response of pellets of alanine and ammonium tartrate with gadolinium oxide exposed to a thermal neutron beam. In particular, the ESR response of these dosimeters as a function of the gadolinium content inside the dosimeter was analyzed. We found that the addition of gadolinium improves the sensitivity of both alanine and ammonium tartrate. However, the use of gadolinium involves a reduces in or abolishes tissue equivalence b…
Study and characterization of polyphenol oxidase from eggplant (Solanum melongena L.)
2011
ABSTRACT: In this study the catecholase and cresolase activities of eggplant polyphenol oxidase (PPO) were investigated. Enzyme activity was determined by measuring the increase in absorbance using catechol as substrate and 3-methyl-2- benzothiazolinone hydrazone (MBTH) as coupled reagent. The effects of substrate specificity, heat inactivation, temperature, pH, and inhibitors were investigated to understand the enzymatic alteration of ready-to-eat preparations. Browning of vegetables was determined through a colorimeter. Decrease of lightness (L*) and increase of color difference values (ΔE*) were correlated with tissue browning. Antibrowning agents were tested on PPO under the same condit…
Organisaation vihreä työkalu : Green Office -ympäristöjärjestelmän vaikutukset organisaatiossa
2010
Ilmastonmuutos herättää keskustelua kansalaisissa ja nykyään myös entistä enemmän organisaatioissa. Kustannuksia syntyy, kun ympäristövaikutuksia ja sitä kautta ilmastonmuutosta pyritään hidastamaan, mutta huomattavasti vähemmän kuin ilmastonmuutoksen seurauksista voi pahimmillaan syntyä, ellei asiaan puututa ajoissa. Ympäristöjärjestelmä on yksi keino ottaa ympäristövastuu kokonaisvaltaisesti organisaatiossa huomioon. Lisäksi sidosryhmien painostus, kiristyvät lait ja asetukset sekä kilpailuedun tavoittelu ohjaavat organisaatioita ympäristöjärjestelmien käyttöönottoon. Niin kutsuttu kevennetty ympäristöjärjestelmä voi olla ISO 14001 -standardia tai EMAS-järjestelmää sopivampi ratkaisu toim…
Industrial application of selected lactic acid bacteria isolated from local semolinas for typical sourdough bread production
2016
Abstract Four obligate heterofermentative lactic acid bacteria (LAB) strains (Weissella cibaria PON10030 and PON10032 and Leuconostoc citreum PON 10079 and PON10080) were tested as single strain starters, mono-species dual strain starters, and multiple strain starter for the preparation and propagation of sourdoughs for the production of a typical bread at industrial level. The kinetics of pH and TTA during the daily sourdough refreshments indicated a correct acidification process for all trials. The concentration of lactic and acetic acid increased consistently during fermentation. The resulting molar ratios between these two organic acids in the experimental trials were lower than those o…
Innovazione e Imprenditorialità. Il ruolo degli spin-off universitari.
2013
Oggi il ruolo delle Università non si limita più soltanto alle tradizionali attività di formazione e di ricerca. La cosiddetta Seconda Rivoluzione Accademica ha attribuito alle Università una "terza missione", che consiste nella valorizzazione e commercializzazione della conoscenza accedemica sul mercato. L'Università diviene così "entrepreneurial university" creando valore non solo in termini di conoscenza ma anche di innovazione e sviluppo economico. Il libro intende approfondire il ruolo che le Università rivestono nel processo di trasferimento di conoscenza innovativa al mercato tramite la costituzione di imprese spin-off. Viene evidenziato come, attraverso il supporto di apposite strut…
Predicting Social Distancing Intention and Behavior During the COVID-19 Pandemic: An Integrated Social Cognition Model.
2020
Abstract Background Social distancing is a key behavior to minimize COVID-19 infections. Identification of potentially modifiable determinants of social distancing behavior may provide essential evidence to inform social distancing behavioral interventions. Purpose The current study applied an integrated social cognition model to identify the determinants of social distancing behavior, and the processes involved, in the context of the COVID-19 pandemic. Methods In a prospective correlational survey study, samples of Australian (N = 365) and U.S. (N = 440) residents completed online self-report measures of social cognition constructs (attitude, subjective norm, moral norm, anticipated regret…
Determinants of Individual Investment Decisions in Investment-Based Crowdfunding
2017
We investigate determinants of investment decisions in investment-based (equity and real estate) crowdfunding, using a novel investment-, investor- and campaign-level database. We find that this market is a man's world, with nearly 93% of investments made by men. Consistent with behavioral and finance theories, we find that women invest less in the riskiest investments but more in safer ones. Further analyses show that these findings are better explained by differences in risk aversion than differences in overconfidence between men and women. Investors located in an area considered more "sociable" (socially friendly) also invest more, but only if the investor is a woman. Overall, the findin…
