Effect of muscle type and animal category on fatty acid composition of bresaola made from meat of Cinisara cattle: preliminary investigation
2020
The bresaola could represent an alternative commercial opportunity for autochthonous dairy cattle farms. Therefore, a study was carried out to investigate the fatty acid (FA) composition of bresaola made using Semimembranosus (SMm), Semitendinosus (STm), and Biceps brachii (BBm) muscles from grazing young bulls (GB), housed young bulls (HB) or grazing adult cows (AC) of Cinisara breed. Animal category, fat content, feeding system, and type of muscle influenced the FA composition of bresaola. Fatter products, made from AC and HB meat, or with STm and BBm muscles showed lower polyunsaturated/saturated FA ratio. The bresaola from young bulls fed pasture-based diet showed an increased polyunsat…
Essential Oil Composition of Stems and Fruits of Caralluma europaea N.E.Br. (Apocynaceae)
2010
The essential oil of the stems and fruits of Caralluma europaea (Guss.) N.E.Br. (Apocynaceae) from Lampedusa Island has been obtained by hydrodistillation and its composition analyzed. The analyses allowed the identification and quantification of 74 volatile compounds, of which 16 were aromatic and 58 non-aromatic. Stems and fruits contained 1.4% and 2.7% of aromatic compounds respectively, while non-aromatic were 88.3% and 88.8%. Non-aromatic hydrocarbons were the most abundant compounds in both organs, followed by fatty acids. Data showed differences in the profiles between stems and fruits which shared only eighteen compounds; stems accounted for 38 compounds while fruits for 53. Fruits …
Opuntia cladodes as functional ingredient in durum wheat bread: rheological, sensory, and chemical characterization
2021
Cladodes are considered by-products of Opuntia ficus-indica cultivation. Their addition as source of antioxidants to durum wheat breads could have effects on preventing cardiovascular diseases, cancers, and inflammation. The inclusion of 0-5-10-15% cladodes, harvested in three different locations, on quality and antioxidant properties of fortified durum wheat breads has been evaluated. The enrichment with 10% of cladodes resulted in an increase in the content of total phenolics (14.8 vs 2.7 mg GAE/100 g of control bread), a decrease of IC50 (3.28 vs 49.7 mg/ml of control bread), good rheological characteristics of loaves and largely positive evaluation by panel test. Fortification with 15% …
Analysis of the Parameters Affecting the Stiffness of Short Sisal Fiber Biocomposites Manufactured by Compression-Molding
2021
The use of natural fiber-based composites is on the rise in many industries. Thanks to their eco-sustainability, these innovative materials make it possible to adapt the production of components, systems and machines to the increasingly stringent regulations on environmental protection, while at the same time reducing production costs, weight and operating costs. Optimizing the mechanical properties of biocomposites is an important goal of applied research. In this work, using a new numerical approach, the effects of the volume fraction, average length, distribution of orientation and curvature of fibers on the Young’s modulus of a biocomposite reinforced with short natural fibers were stud…
Valutazione sperimentale delle componenti del campo di radiazioni in un irradiatore neutronico con sorgenti 241Am-Be e confronto con simulazioni Mont…
2014
Il presente lavoro riguarda la valutazione sperimentale delle componenti gamma e neutronica del campo di radiazioni presente in diversi punti all’interno del canale di irraggiamento di un irradiatore neutronico con sorgenti 241Am-Be. Per la componente gamma sono stati considerati due contributi: il primo associato a gamma di energia di 60 keV, dovuto al decadimento dell'241Am; il secondo a gamma di energia 2,2 MeV, dovuto alla cattura radiativa dei neutroni da parte dello schermo biologico (acqua) che circonda le sorgenti. Per le misure sperimentali sono stati utilizzati dosimetri tipo TLD700 in due diverse configurazioni: TLD "nudi" per misura della dose relativa al campo gamma totale e TL…
Application of Monte Carlo simulation to design a modular 241Am-Be neutron irradiator
2010
Most of neutron irradiators are realized with neutron sources located at fixed positions and accordingly the characteristics of neutron spectrum previously assessed do not change. However, an interesting chance is to have a modular facility, capable of varying conditions of irradiation and setting the prevalence of fast or thermal neutron spectrum components. In this work we report the Monte Carlo studies devoted to design a modular 241Am-Be neutron irradiator making use of different moderators (water, graphite, polyethylene and so on) in order to obtain a neutron energy distribution useful to test neutron detectors or personal dosemeters. The optimization of thicknesses and shape of the mo…
La modifica dell'art. 41 della Costituzione: testo e contesto
2022
Il contributo analizza in chiave critica l'intervento di riforma costituzionale dell'art. 41 nel quadro degli altri interventi di riforma costituzionale realizzati o promossi nel corso della XVIII legislatura. Il testo esamina le novità introdotte dalla legge costituzionale n. 1 del 2022 al secondo e al terzo comma dell’art. 41 Cost. anche alla luce delle più recenti evoluzioni del quadro normativo derivante dagli interventi di sostegno alla ripresa economica successivi alla pandemia.
