Phytochemical and Pharmacological Evaluation of the Residue By-Product Developed from the Ocimum americanum (Lamiaceae) Postdistillation Waste
2021
The yield of essential oils in plants is not high and postdistillation wastes rich in phenolic compounds could be used to enhance the profitability of essential oil-bearing plants. The aim of the study was to evaluate polyphenols in a dry extract obtained from the postdistillation waste of the American basil (Ocimum americanum L.) herb, and to conduct the screening of its pharmacological activities. Rosmarinic acid, caffeic acid and rutin were identified in the extract using high-performance thin-layer chromatography. The high-performance liquid chromatography analysis found the presence of a plethora of polyphenols in the extract. Rosmarinic acid, luteolin-7-O-glucoside and rutin were as t…
Improving the Downwind Sail Design Process by Means of a Novel FSI Approach
2021
The process of designing a sail can be a challenging task because of the difficulties in predicting the real aerodynamic performance. This is especially true in the case of downwind sails, where the evaluation of the real shapes and aerodynamic forces can be very complex because of turbulent and detached flows and the high-deformable behavior of structures. Of course, numerical methods are very useful and reliable tools to investigate sail performances, and their use, also as a result of the exponential growth of computational resources at a very low cost, is spreading more and more, even in not highly competitive fields. This paper presents a new methodology to support sail designers in ev…
Metal salen complexes as ethylene polymerization catalysts - effect of catalytic system composition on its activity and properties of polymerization …
2008
Zsyntetyzowano i zastosowano [po aktywacji metyloaluminoksanem (MAO) lub Et2AlCl] w charakterze katalizatorów niskociśnieniowej polimeryzacji etylenu serię salenowych kompleksów metali przejściowych różniących się rodzajem atomu centralnego (M=Ti, Zr lub V) i budową chemiczną ligandu (schemat A). Stwierdzono, że salenowe kompleksy cyrkonu są aktywne w polimeryzacji jedynie wówczas, gdy aktywator stanowi MAO, natomiast kompleksy tytanu i wanadu są aktywniejsze w przypadku gdy kokatalizatorem jest typowy związek glinoorganiczny - dietylochloroglin. Aktywność kompleksów w układzie z Et2AlCl zmienia się w szeregu V>Ti>>Zr?0, podczas gdy w odniesieniu do kompleksów aktywowanych MAO maleje ona w …

“At the Western Palace”: The Dehumanization of Whiteness, Americanness, and Chinese-Americanness in Maxine Hong Kingston’s The Woman Warrior
2021
The dehumanization of whiteness in Maxine Hong Kingston’s The Woman Warrior (1976) inheres in the overarching ghosthood metaphor. While first generation Chinese American immigrants in The Woman Warrior attribute the power of transforming people into ghosts to the United States of America as a country, the questioning of a person’s humanity by calling them a “ghost” is not reserved for white people alone. Chinese American immigrants also run the risk of losing their humanity and becoming ghosts if they renounce their relatives and their heritage. The husband of the first-person narrator’s Chinese aunt, Moon Orchid, is an example of a Chinese American man, who turns into a ghost on account of…

La consolidación de un proyecto iberoamericano de educación. La experiencia del Geoforo. Balance anual de 2011
2011
Los problemas sociales y ambientales que existen en este siglo XXI son de una gran magnitud. Pero la escuela sigue anclada en concepciones del siglo XIX, al mismo tiempo que se priorizan aspectos técnicos de la comunicación y se abandonan los valores y criterios de un análisis social. En este trabajo damos cuenta de las iniciativas llevadas a cabo por un grupo de profesores a través del Geoforo, que aprovecha las facilidades del ciberespacio, a partir del portal Geocrítica de la Universidad de Barcelona, para difundir sus inquietudes y generar la participación de educadores y estudiantes Su objetivo es estudiar los problemas comunes que existen entre los docentes para acercar la educación e…
Diversidades geográficas e construção de um conhecimento crítico para participar em rede. A experiência do Geoforo Iberoamericano. Balanço inicial
2011
The diversity of people, cultures and social situations in Latin America countries does not obstruct the critical and honest dialogue concerning the research carried out on the learning of world problems. Geography, as a science, can contribute to this challenge, but it needs, then, to leave the intellectual, corporate and academic obstacles that prevent its study by the pupils. In this work we communicate the initiatives developed by a group of teachers by means of the Geoforo, which takes advantage of the facilities of the cyberspace, from the Geocrítica portal of the University of Barcelona.
Scientific productivity and collaboration in viticulture and enology in Latin American countries
2013
[EN] The aim of this study was to analyze the scientific activity of Latin American researchers in viticulture and oenology through bibliometric analyses of articles included in the Science Citation Index Expanded database for the period of 2006 to 2010. A total of 917 research articles were published in 364 domestic and international journals. We highlight the important growth in the number of research papers published during the period, especially in Brazil, Argentina and Chile, as well as an increasing number of international collaborations, mainly with non-American grape- and-wine producing countries. A social network analysis of collaborations between institutions and countries was als…
Evoluzione di sistemi deposizionali di piattaforma continentale durante il Pleistocene superiore - Olocene: analisi sedimentologica di due carote pre…
2016
E’ stato condotto uno studio sedimentologico di due carote prelevate nell’offshore della Sicilia settentrionale allo scopo di analizzare i cambiamenti di regime deposizionale verificatisi nel Pleistocene superiore - Olocene. Sulle due carote, provenienti dal Golfo di Termini Imerese (2,74 m di lunghezza, profondità -126 m) e dalla Baia di Carini (1,35 m di lunghezza, profondità -194 m), sono state anche eseguite analisi geochimiche e micropaleontologiche. Da un punto di vista granulometrico in entrambe le carote si può notare che la parte inferiore è principalmente costituita da una granulometria grossolana (ghiaia, ghiaia sabbiosa) che passa ad una granulometria di tipo argillo-siltosa nel…
