Nutritional Value of Italian Pistachios from Bronte ( Pistacia vera, L.), Their Nutrients, Bioactive Compounds and Antioxidant Activity  [PDF]
Laura D’Evoli, Massimo Lucarini, Paolo Gabrielli, Altero Aguzzi, Ginevra Lombardi-Boccia
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.614132
Abstract: This study gives an overview on the nutritional value, bioactive compounds and antioxidant activity (ABTS and FRAP) of Bronte’s pistachio (Pistacia vera, L., cv. Bianca) from Sicily (Italy). Bronte’s pistachios are rich in fat, protein, dietary fiber, trace elements (Fe, Zn, Cu, Mn) and minerals (Ca, P, K, Mg, Na). Lipids mainly consist of MUFA (33.8 g/100g), primarily oleic acid (32.4 g/ 100g); PUFA is mostly represented by linoleic acid (7.49 g/100g). Bronte’s pistachios are also a valuable source of bioactive compounds such as total polyphenols (501.5 mg/100g), lutein (1.26 mg/100g), β-carotene (0.18 mg/100g), γ-tocopherol (19.2 mg/100g) and phytosterols (134.4 mg/100g). Among phytosterols, the main is β-sitosterol (86% of total content), followed by Δ5-avenasterol (6.3%). Phytic acid content is 1763 mg/100g; Ins(1,2,4,5,6)P5 and Ins(1,2,3,4,5,)P5 have been detected too (31 mg/100g and 10 mg/100g, respectively). The antioxidant activity was determined both in hydrophilic and lipophilic fraction of pistachios, showing >80% of the total antioxidant activity in the hydrophilic, predominately due to phenolic compounds.

Foods , 2013, DOI: 10.3390/foods2030352
Abstract: Tomatoes and tomato products are rich sources of carotenoids—principally lycopene, followed by β-carotene and lutein. The aim of this work was to study the effect of heat treatment on carotenoid content in cherry tomatoes. Raw and canned products were sampled and analysed; furthermore whole, skin and pulp fractions of cherry tomatoes were analysed when raw and home-processed, in order to better understand heat treatment effects. Lycopene content in canned tomatoes was two-fold higher than in raw tomatoes (11.60 mg/100 g versus 5.12 mg/100 g). Lutein and β-carotene were respectively 0.15 mg/100 g and 0.75 mg/100 g in canned tomatoes versus 0.11 mg/100 g and 1.00 mg/100 g in raw tomatoes. For home-processed tomatoes, β-carotene and lutein showed a content decrease in all thermally treated products. This decrease was more evident for β-carotene in the skin fraction (?17%), while for lutein it was greater in the pulp fraction (?25%). Lycopene presented a different pattern: after heat treatment its concentration increased both in the whole and in pulp fractions, while in the skin fraction it decreased dramatically (?36%). The analysis of the isomers formed during the thermal treatment suggests that lycopene is rather stable inside the tomato matrix.
Phenolic Acids Content and Nutritional Quality of Conventional, Organic and Biodynamic Cultivations of the Tomato CXD271BIO Breeding Line (Solanum lycopersicum L.)  [PDF]

Food and Nutrition Sciences (FNS) , 2016, DOI: 10.4236/fns.2016.712106
Abstract: This study was undertaken to evaluate the influence of growing systems (conventional, organic and biodynamic performed with two types of manuring) on some nutritional traits of the tomato breeding line CXD271BIO (Solanum lycopersicum L.). Experimental fields were in the same geographical area and the cultivations were performed over five years. The content of macronutrients, minerals (Ca, K, Mg, P, Na), trace elements (Fe, Zn, Cu, Mn) and phenolic acids (chlorogenic, caffeic, p-coumaric and ferulic acids) was determined. The biodynamic A growing system showed the highest protein and carbohydrates content compared to the other growing systems. Data on minerals and trace elements content showed significant differences (mainly in Ca, Na, Fe and Zn content) between conventional and biodynamic tomatoes, whereas no major impact of the fertilization among organic and the two biodynamic growing systems was observed. Appreciable differences in phenolic acids biosynthesis were observed, with the year of harvest showing a marked effect especially on chlorogenic, p-cumaric and ferulic acids content. Conversely, the cultivation system did not show major influence. Principal Components Analysis (PCA), performed on mineral and phenolic acids content, substantiated the large effect of the year of harvest, also suggesting an effect of the conventional cultivation system.

Food and Nutrition Sciences (FNS) , 2017, DOI: 10.4236/fns.2017.85031
Abstract: The study provides original data on the compositional profile (macronutrients, dietary fiber, mineral and trace elements, bioactive molecules) of an Italian typical plant foods, Treviso Red Cichory, studying the two cultivars (Early, Late) grown following two different traditional cultivation systems. For two consecutive years plants from three growing areas, were studied. Major, significant differences, between Early and Late cultivars, were observed in minerals (Ca, Mg, P), trace elements (Fe, Zn) and bioactive molecules content. The Late cv. was found the richest in minerals and trace elements content than the Early cv., but for Ca. Treviso Red Cichory was found a valuable source of bioactive molecules such as ascorbic acid, anthocyanins and total polyphenols. The Early cv. showed a significantly higher (p < 0.05) ascorbic acid and total anthocyanins content (8.63 and 92.15 mg/100g, respectively) than the Late cv. (6.15 and 24.38 mg/100g, respectively), by contrast total polyphenols content was significantly higher (p < 0.05) in the Late cv. A marked variability in bioactive molecules content among the growing areas was found only for the Late cv. The observed differences between the

Abstract: O sítio arqueológico de Via Neruda, localizado em Sesto Fiorentino (Floren a, Itália) e datado da Idade do Bronze, apresentava uma quantidade de macro restos vegetais, entre os quais muitos carv es e alguns lenhos, que s o o objeto do presente trabalho. Entre os carv es, alguns foram considerados como estando relacionados com estruturas ligadas à ocupa o humana. O objetivo do presente trabalho é perceber quais os conhecimentos e o uso dado ao lenho por esta comunidade humana da Idade do Bronze. As análises antracológicas dos carv es e lenhos indicam a existência de uma floresta sub-húmida de planície. Os resultados obtidos e a sua compara o com outros estudos sugerem a selec o de Ulmus, Quercus e Fraxinus pelas suas características, sendo que Sorbus, Acer, Prunus e Populus possivelmente foram utilizados sobretudo pela sua disponibilidade no entorno do sítio arqueológico. Palavras-chave: Carv es, Lenhos, Recursos arbóreos, Ambiente, Idade do Bronze. Abstract The archaeological site of Via Neruda, located in Sesto Fiorentino (Florence, Italy) and dated to the Bronze Age, had a number of macro plant remains, including many wood and charcoal, which are the object of this work. Among the charcoals, some were considered to be related to structures associated with human occupation. The aim of this study is to understand the knowledge and uses of wood by this Bronze Age human community. Anthracological analyses of charcoals and wood indicate the existence of a sub-humid lowland forest. The results and their comparison with other studies suggest the selection of Ulmus, Quercus and Fraxinus due to their characteristics, and Sorbus, Acer, Prunus and Populus were possibly used primarily by their availability in the vicinity of the archaeological site. Key words: Charcoal, Wood, Arboreal resources, Environment, Bronze Age.

Abstract: In todays economics, the fact that information is a major factor of production and of increasing importance as a source of competitive advantage is a generally accepted truism. The trend towards global markets has strongly impacted the competitive situation of many enterprises. Never has the economic environment been subject to so many drastic and rapid changes. This put new weight factors on the requirements for design of business process. This paper explores the case of an Italian legal office that has studied more and more innovative solutions both to satisfy the demands of the clienteles and to oppose the action of the new competitors. Comparing classic models and the theories of Porter with the characteristics and needs of new economy, it shows as the ability to possess, to easily have access, to creatively use of information constitutes one of the more strategic sources of the competitive advantage.
Riflessioni sull'accesso globale al diritto: analisi dei sistemi di ricerca multilingue Considerations on global access to rights: anlysis of multilingual search tools

Abstract: In the contemporary society there is the need of a common understanding of the legal issues of the different court systems, in the academy as well as in the legal profession, in the business world, and in the public administration services. At the same time there is a strong pressure in order to preserve their sense and value, but it is very difficult to satisfy both the needs due to the complexity of the legal language and of the ways to express law in the different systems. Unlike other disciplines where a correspondence of ideas and concepts in different languages exists, there are some difficulties in rights due to the nature of the legal language and its correlation to the native legal system. The article offers some ideas on the requirements of multilingual systems for legal information research through the exam of conceptual and linguistic aspects to be taken into account in order to develop those systems underlining the problems related to legal translation, comparative law, and techniques to elaborate natural language to access and retrieve information in a distribute context. Recommendations deal on a side with methods to define equivalences between legal concepts, on the other with forms of collaboration among institutions (responsible for indexing and distribution of legal information), to guarantee the access to information to each citizen in the preferred language In una società globalizzata come quella odierna vi è una forte necessità, nell’accademia, nella professione legale, nel mondo degli affari ed in quello dei servizi della pubblica amministrazione, di una comune comprensione dei concetti giuridici dei diversi ordinamenti. Allo stesso tempo si assiste ad una forte pressione verso la conservazione del loro senso e valore. è difficile soddisfare entrambi i requisiti a causa della complessità del linguaggio giuridico e delle diverse modalità utilizzate per esprimere il diritto nei vari sistemi giuridici. A differenza di altre discipline, in cui esiste una corrispondenza tra i concetti espressi nelle varie lingue, nel diritto insorgono serie difficoltà di interpretazione dovute alla natura della terminologia giuridica, intimamente legata al sistema giuridico di riferimento. L'articolo offre alcuni spunti di riflessione sui requisiti dei sistemi di ricerca multilingue dell'informazione giuridica, esaminando gli aspetti linguistici e concettuali che devono essere presi in considerazione nello sviluppo di tali sistemi e soffermandosi sulle problematiche della traduzione giuridica, del diritto comparato e delle tecniche di elaborazione del

Abstract: A hot phase of the interstellar medium has now been detected and studied in several objects through its X-ray emission. A proper assessment of its characteristics is relevant for our understanding of several aspects of galaxy properties, from the large scale distribution of matter to the stellar and galaxian evolution, to the dynamics of systems and to the feeding of a central black hole. I will briefly summarize our current understanding of some of the main issues related to the hot gaseous component in galaxies that are fast evolving given the ever more striking and interesting details provided by the X-ray satellites currently operating. I hope to convince you that the X-ray characteristics of the hot gas are quite complex, both in morphology and spectra, in a wide range of objects, which should promote greater efforts in understanding the role played by this component in all galaxies.
