    No full text
    Electroencephalography (EEG) is a technique for the acquisition of electrical brain signals. In recent years the increase of information acquired from signal analysis has generated a large amount of data; therefore, the development of tools for analysis has become necessary. In this paper, the mEEG prototype for EEG data managing is presented. It offers a user-friendly communication solution to exchange data between physicians and biomedical engineers. Features can be used for: (i) perform a fast diagnoses; (ii) show reports about clinical information; (iii) store and retrieve neurological data

    The rhizomes of the Zingiberaceae family are a vegetable widely used in many Asian countries, and their medicinal functions have been broadly discussed and accepted in many traditional recipes. In this study, 18 species of five genus of Zingiberaceae plants from Taiwan area were collected and analyzed for their functional properties. Methanolic extracts of the plants were analyzed for their total phenol compounds, alpha,alpha-diphenyl-beta-picrylhydrazyl (DPPH) scavenging activity, and reducing power. Antimicrobial activity of these samples was also determined. The results showed that the total phenol compounds of the Alpinia genus averaged 17, 30 mg/g for Curcumas, and the highest, 36.5 mg/g for Vanoverberghia sasakiana. Antioxidant performances were best observed in Vanoverberghia and Hedychium, both 89%, and DPPH scavenging activity followed similar trends. Particularly, Zingiber oligophyllum, considered as a traditional medicinal plant used in Taiwan exhibited low DPPH scavenging activity and reducing power. Most Zingiberaceae plant extracts exhibited antimicrobial activity against all tested food microorganisms. Hedychium and Vanoverberghia, did not show antimicrobial activities on Escherichia coli and Vibrio parahaemolyticus. This study is a positive demonstration of the utility of screening Taiwan's endemic Zingiberaceous plants for their food and medicinal uses

    El presente artículo plantea una reflexión sobre la evolución del palmeral de Elx partiendo del interés por mantener en vigor este espacio. El autor lo sitúa primeramente en su contexto histórico y geográfico para luego remontarse a sus orígenes, ligados al aprovechamiento de la palmera en la economía local y de la región. Sin embargo, los intereses culturales y turísticos predominantes en la actualidad pueden contribuir a la desaparición paulatina de los antiguos usos rurales de este entorno. En el artículo se examina la relación entre el palmeral y el desarrollo urbano de Elx, la conversión en suelo público y los riesgos de degradación inherentes a los cambios producidos.The present article discusses the evolution of the palm grove of Elx, starting with the interest to maintain this alive. The author first situates the palm grove in its historical and geographical context and then goes back to its origins, linked to the use of the palm in the local economy and the region. However, the predominant cultural and tourism interests at present can contribute to the gradual disappearance of the old rural uses of this environment. The article examines the relationship between the palm grove and the urban development of Elx, the conversion to public land and the risks of degradation inherent to the changes produced
