Sviluppo di una equazione di stima dello spessore del grasso di copertura della coscia suina
No full textThis research aimed to develop a simple mathematical model able to predict the subcutaneous fat thickness of pig thighs starting from the carcass traits as weight, backfat and l.dorsi thickness, and weight of the trimmed thighs. A stepping model-building technique using the General Regression Model method, involving two steps, was implemented. Firstly, the best fit equation was developed which was able to describe relationships among the investigated variables. Thereafter, a validation step, to evaluate the predictive ability of the model, was performed against a set of independent data from that used in building step. Results proved that both the quadratic and interactive terms of carcass traits could be successfully used to predict the subcutaneous fat thickness of pig thighs. About 82% of the predicted data were in agreement with the experimental measurements
Effetto dell’integrazione dietetica con acido pantotenico sulle caratteristiche della carcassa e della carne del suino pesante
No full textTo determine the effect of dietary panthotenic acid on carcass and meat quality traits, two groups of heavy pigs were fed, from 107 kg live weight till to slaughtering (168 kg), a diet containing either 10 or 110 ppm of added pantothenic acid as calcium pantothenate. After grading, 20 carcases of each group were dissected and lean and adipose cuts were weighed. Further, pH and colour measurements were carried out on biceps femoris of each left thigh at 1 and 24 h post mortem. Vitamin supplementation increased lean meat (50.91 vs. 47.86%) and total carcass lean cuts content (63.40 vs. 60.97%) and reduced backfat thickness (28.30 vs. 33.50 mm) and adipose cut percentage (24.10 vs. 25.78) without affecting markedly pH and colour of biceps femoris
Aspetti tecnologici e microbiologici del salame di suino Mora Romagnola
No full textCon la presente ricerca sono state studiatealcune caratteristiche qualitative di salamitradizionali, ottenuti da carni di suini derivatidalla razza Mora Romagnola allevati all’apertonel circuito biologico, con aggiunta o menodi nitriti (150 ppm) e di una coltura starter dibatteri lattici. La composizione chimica deisalami prodotti non differisce molto da quellariportata per simili tipologie di produzioneottenute anche a livello industriale. L’impiegodei nitriti ha ridotto lievemente i cali di pesonelle fasi intermedie di stagionatura, speciese aggiunti insieme allo starter di batterilattici, ma non ha influenzato il calo finaleed ha prodotto salami con un minor gradodi ossidazione dei lipidi e con un colore piùrosso. Il pH è risultato abbastanza elevatodurante tutta la fase di preparazione ematurazione del salame in tutti i gruppi,con i valori più bassi in quelli aggiunti distarter di batteri lattici. Quest’ultimo sembraessere la variabile con il maggior peso trai lotti soprattutto sulla flora microbica. Imicrorganismi sono stati valutati con metodidi coltura indipendente e convenzionali
Caratterizzazione morfologica di prosciutti freschi colpiti dal difetto di venatura in tre impianti di macellazione
No full textThe morphological characteristics (length, depth, circumference, globosity) andthe weight were recorded on 593 left thighs collected from three slaughterhouses and providedby batches where the risk of veining defect was high. The incidence of the defect variedaccordingly to the slaughter plant, ranging from 31% to 59%. Irrespectively of theslaughterhouse, the raw hams showing an evident venous lattice were characterized by a highdepth which increased with the severity of the defect. Moreover, there was the tendency toobserve the defect in the more globose and in the heavier raw hams
Caratterizzazione del difetto della “cotenna rossa”del prosciutto di Parma
No full textThe aim of this study was to evaluate, in an objective way, the colour of the skin of raw Parma hams, classified subjectively in 3 different classes for the "red skin" defect, and to verify the relationship with muscular colour and pH. Two hundred left-thighs from pigs reared in two different farms, were evaluated subjectively on the basis of the intensity of red skin colour, using a 3 point scale system supported by a photographic standard where 1=defect absent, 2=slight defect and 3=serious defect. Colour of skin and BF muscle and pH of the latter were measured at 24 hour p.m. Results indicate that, red skin defect was present, on average, in the 69.5% of the examined thighs. L* and Hue values decreased and a* and chroma values increased, in both skin and BF tissues, when defect score increased
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
