Preliminary study on microbeads production by co-extrusion technology

AbstractThe present paper describes preliminary results on the development of a batch lab-scale co-extrusion device for the production of alginate beads as carrier for hydrophilic compounds. A dual jet of liquid core (aqueous solution of glucose or vitamin B12 or olive oil) and liquid shell material (aqueous solution of alginates differing for guluronic to mannuronic ratio) was pumped through concentric extrusion nozzles and droplets were formed by means of a rotating fluid jet cutter. The shell of the bead was then hardened in the hardening bath containing a calcium chloride solution. Optimization of the co-extrusion plant accounts for the management of the operative conditions within the hardening unit (incubation time, molarity of the gelling agent), and for the control of the surface-tension-driven breakup of laminar jets which was managed by varying the jet cutter - hardening unit distance. Beads enriched in vitamin B12, that were formed according to the best plant set-up, were tested for the bioactive release when stressed under thermal conditions simulating typical dairy products processes. Cyanocobalamin was retained at all

Developing and Using a Rubric to Provide Feedback and Improve CSD Clinical Writing

The benefits of rubrics have long been established and their use encouraged in various fields of study. The authors sought to create a rubric specific to the needs in CSD to more clearly share expectations for student clinical writing and more comprehensively assess the quality of their writing. The faculty collaborated with the Office of Academic Assessment to develop a rubric to address these issues. The rubric was developed using VALUE rubrics as guidance, as well as the unique requirements for Communication Sciences and Disorders documentation. This specific rubric may be used to grade and provide feedback to improve the comprehension of the many facets of superior clinical writing, provide transparency in grading, and to improve the quality of future documentation. In addition, it provides the professor a framework from which to teach expectations of the document and descriptions of student performance to increase proficiency and effectiveness in grading. It may be used for undergraduate and graduate students in both academic and clinical courses

Contro "Sire Le Mot": Achille Ricciardi "régisseur" e riformatore

This essay focuses on Achille Ricciardi’s experiment, called Teatro del Colore, which is commonly seen, on the one hand, as a not well-done enterprise, on the other, as an old aesthetic proposal made by a "decadent obsessed with symbolism". The essay will try to weaken this last interpretation with the support of unpublished material, present in the correspondence with d'Annunzio (1911-1921). There, Ricciardi affirms the principle of autonomy of the performance and of the régisseur, with respect to whom the spoken word plays an ancillary role. There, a concern about the irremediable delay with which his experiments appeared on the scene is expressed, too. About this, Ricciardi was fully aware, despite what is commonly understood. The correspondence also allows to establish some chronological and compositional issues of the essay on color more precisely and to confirm its inorganic nature, rich in innovative impulses, but in some parts obscure and contradictory.Lo studio si sofferma sul Teatro del Colore di Achille Ricciardi, interpretato da un lato come un’impresa mancata solo sul piano pratico, dall’altro come una proposta estetica nata già vecchia e concepita da un «decadente ossessionato di simbolismo». Si cercherà di moderare quest’ultima linea con l’ausilio di materiale inedito, estratto dal carteggio con d’Annunzio (1911-1921). In esso Ricciardi afferma il principio dell’autonomia dello spettacolo e del régisseur, “mago” della scena, rispetto ai quali la parola svolge un ruolo ancillare. Vi è manifestata, poi, la preoccupazione per il ritardo ormai irrimediabile con cui i suoi esperimenti si affacciavano sulla scena. Una condizione di cui lo sperimentatore, a dispetto dell’opinione comune, fu affatto consapevole. Il carteggio permette, inoltre, di stabilire con più precisione alcune questioni cronologiche e compositive del saggio sul colore, confermando la sua natura ricca di slanci innovatori, ma in alcune parti oscura e contraddittoria

Il paradigma dell’arte sinestetica: la rinascita della messa in scena tragica al teatro greco di Siracusa

The essay describes the main stages of the conception and organization of classical representations in the Greek theater in Syracuse, starting from 1914. Mario Tommaso Gargallo’s and Ettore Romagnoli’s work is set in the age of the open air theater, widespread in Europe since the late nineteenth century, and immediately dialogues with the major expressions of the first avant-garde. The goal of their work was to look at the Greek paradigm to create a new model for the contemporary scene, starting from a staging that can unify together word, music and dance. The National Institute of Ancient Drama (INDA) was able to activate and preserve those exceptional circumstances that, according to Édouard Schuré, had failed in Bayreuth and Orange; and it imposed an ethical and aesthetic model of formal unity, which leaved a mark on the Italian indoor scene of the early twentieth century

Ars una. L'insegnamento del metodo mimico dopo Orazio Costa

The article investigates the teaching of the mimic method after Orazio Costa. Nourished by poetic, philosophical and neuroscientific instances, the mimic method was imparted by Costa to generations of students, firstly at the Accademia Nazionale d’Arte Drammatica and at the Centro Sperimentale di Cinematografia and, later, at the Centro di avviamento all’espressione in Florence and at the Scuola di espressione e interpretazione scenica in Bari. Aware that a failure to formalize the method would compromise its diffusion, Costa leaves the future of the method to his pupils, giving them the task of continuing the inseparable paths of research and teaching. The article is based on some interviews made with several currently active teachers, during which the main questions that remained opened in the dialogue with Costa were addressed: their condition as students; his passing the baton to them of; the content that their teaching and research on the method has pursued; finally, the issues regarding the education of a new generation of teachers

Field Inoculation of Bread Wheat with Rhizophagus Irregularis under Organic Farming: Variability in Growth Response and Nutritional Uptake of Eleven Old Genotypes and A Modern Variety

Arbuscular mycorrhizal fungi (AMF) promote crop growth and yield by increasing N and P uptake and disease resistance, but the role of field AMF inoculation on the uptake of micronutrients, such as Fe and Zn, and accumulation in plant edible portions is still not clarified. Therefore, we studied the effect of field inoculation with Rhizophagus irregularis in an organic system on 11 old genotypes and a modern variety of bread wheat. Inoculation increased root colonization, root biomass and shoot Zn concentration at early stage and grain Fe concentration at harvest, while it did not modify yield. Genotypes widely varied for shoot Zn concentration at early stage, and for plant height, grain yield, Zn and protein concentration at harvest. Inoculation differentially modified root AMF community of the genotypes Autonomia B, Frassineto and Bologna. A higher abundance of Rhizophagus sp., putatively corresponding to the inoculated isolate, was only proved in Frassineto. The increase of plant growth and grain Zn content in Frassineto is likely linked to the higher R. irregularis abundance. The AMF role in increasing micronutrient uptake in grain was proved. This supports the introduction of inoculation in cereal farming, if the variable response of wheat genotypes to inoculation is considered
