Development of high-performance thin layer chromatography method for identification of phenolic compounds and quantification of rosmarinic acid conte…
2020
ABSTRACT Aim: Representatives of Nepetoideae Burnett subfamily are promising species of the Lamiaceae Martinov family because of accumulating such valuable groups of secondary metabolites as terpenoids and polyphenols. A high-performance thin layer chromatography (HPTLC) fingerprint method for the qualitative determination of phenolic compounds and for the quantification of rosmarinic acid (RA) content in methanol extracts of five species of this subfamily was developed for the first time. Materials and Methods: Dried aerial parts of Dracocephalum moldavica L., Ocimum americanum L., Lophanthus anisatus (Nutt.) Benth., Monarda fistulosa L., and Satureja hortensis L. collected in flowering pe…
Ei-amerikkalaisen mustan hybridisyys Adichien romaanissa Americanah
2014
Tutkin hybridisyyttä, identiteettiä ja rasismia Chimamanda Ngozi Adichien kolmannessa romaanissa Americanah (2013). Hybridisyyttä on tutkittu postkoloniaalisen kirjallisuudentutkimukseen kuuluvana, mutta se taipuu toisen kulttuurin omaksumisen tutkimiseen muissakin tilanteissa, esimerkiksi maahanmuutossa ja pakolaisuudessa. Identiteetti kuvaa ihmisen syvintä ja ominta olemusta. Puhutaan myös hybridisestä identiteetistä, kun ihminen omaksuu kahden tai useamman kulttuurin toimintatapoja. Americanah käsittelee rasismia erityisesti Yhdysvalloissa, sillä rotusyrjintä on osa amerikkalaista kulttuuria.
Sleepless in Carver Country: Insomnia and Existential Crisis in Raymond Carver’s Short Fiction
2020
Chez Raymond Carver, la nuit n’est jamais uniquement une toile de fond réaliste. Dans ses nouvelles se déroulant après la tombée de la nuit, Carver joue à déconstruire les clichés généralement associés au confort de l’intimité nocturne et du lit conjugal. L’insomnie qui frappe certains de ses personnages les renvoie au contraire à leur complète solitude et à leur condition de mortels. Cet article cherche donc à voir comment la nuit blanche carvérienne est utilisée métaphoriquement pour exprimer l’angoisse de personnages souvent peu expansifs, qui veulent leur part du Rêve américain mais se retrouvent pris au piège d’un cauchemar existentiel. In Raymond Carver’s short fiction, the night is n…
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…
“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…
