Tecnologie alimentari: problemi svolti di operazioni unitarie

2020

Le Operazioni Unitarie (OU) costituiscono gli elementi base del flow-sheet di un processo produttivo. Le OU fondamentali comuni a più processi si basano sugli stessi principi, relativi a fenomeni chimico-fisici e biologici, e quindi su tecnologie simili, anche se naturalmente le apparecchiature, i materiali di costruzione e le condizioni operative devono essere adattate. Questa scomposizione logica, permette di realizzare un qualsiasi processo mediante una sequenza ottimale di OU (Biardi G., ed. Città Studi, 2009), in cui occorre che lo studente acquisisca le medesime conoscenze e competenze. Per tale motivo le OU, vengono impartite in un insegnamento a parte, con un metodo “unitario”, che …

Variantes organizativas generadas por las tecnologías de la información. Un estudio en los centros de primaria de la Comunidad Valenciana

2009

En esta tesis hemos analizado las variantes organizativas que se producen en dos centros educativos de primaria de la Comunidad Valenciana al introducir las tecnologías informáticas. Para estudiar este fenómeno educativo hemos optado por la corriente de investigación educativa basada en la metodología de corte cualitativo y por el estudio de casos como instrumento metodológico. Entre los resultados alcanzados cabe señalar que encontramos en la actualidad tecnologías informáticas en todo tipo de dependencias de las escuelas, es necesario el establecimiento de criterios para la organización de su utilización. También anotamos que la cantidad de tecnologías informáticas del centro ha de ser pr…

Presentazione

2008

Nel presente volume di Cesare Sposito, l’esigenza di indagare nel campo dell’accoglienza e di ritrovare quei caratteri della ricerca scientifica che ne definiscono la storia, la tecnica, i materiali e non di meno le emozioni, diviene l’obiettivo che l’Autore vuole raggiungere. Il volume si struttura in quattro parti. La prima parte, un tour tipologico attraverso i secoli, per usare un linguaggio più adatto, analizza l’importanza del viaggio come strumento di apprendimento e di svago, documenta come sia cambiata la tipologia degli utenti e come, di conseguenza, si sia trasformata la tipologia architettonica, in uno alle funzioni che essa accoglie al suo interno. L’excursus temporale preso in…

Monitoring Commercial Starter Culture Development in Presence of Red Grape Pomace Powder to Produce Polyphenol-Enriched Fresh Ovine Cheeses at Indust…

2021

Red grape Nero d’Avola cultivar grape pomace powder (GPP) was applied during fresh ovine cheese production in order to increase polyphenol content. Before cheeses were produced, the bacteria of a freeze-dried commercial starter culture were isolated and tested in vitro against GPP. Two dominant strains, both resistant to GPP, were identified. Thestarter culture was inoculated in pasteurized ewe’s milk and the curd was divided into two bulks, one added with 1% (w/w) GPP and another one GPP-free. GPP did not influence the starter culture development, since lactic acid bacteria (LAB) counts were 109 CFU/g in both cheeses at 30 d. To exclude the interference of indigenous LAB, the pasteurized m…

Electrochemical incineration of oxalic acid in the presence of NaCl

2008

Recent researches have demonstrated that electrochemical methods offer an attractive alternative to traditional routes for treating wastewaters containing toxic or/and refractory organic pollutants. The effectiveness of the electrochemical treatment depends on many factors including the presence in solution of specie able to act as mediators. In particular, the effect of chloride ions on the performances of the process has been the object of numerous researches. However, up to now, many practical and theoretical aspects about this argument are not completely clear. In the present work, the anodic incineration of oxalic acid (OA) in the presence of NaCl has been investigated with the aim of …
