    Data from 40 monitoring wells across 9 sections of the lower Tarim River from 2000 to 2006 were analyzed to investigate the relationship between the transmission loss per unit river length and the change in groundwater depth. The relationship between the rise of the groundwater table (y) and the distance from the main river reach (x) was then assessed through regression analysis. We concluded that the maximum affected area was 1933 m away from the main river reach in the Alagan section, and the minimum affected area was 576 m away in the Kaogan section. In addition, after 8 water deliveries, the volume for recharging the groundwater was 78 248.7 x 10(4) m(3). Using the Yingsu section as an example, we found that the volume for recharging the groundwater decreased with additional periods of delivery except after the second and sixth water delivery The results revealed that the beneficial effect of an ecological water conveyance project on the ecosystem in the lower Tarim River is a long-term process. These findings may be useful for guiding studies on instream flow requirements and provide a scientific basis for implementing similar ecological projects in other areas. (C) 2009 Elsevier Ltd.

    TRANSLATING THE VISUAL: CHEN CHIEH-JEN’S WORK

    Get PDF
    Nacido en Taiwán y actualmente residente en Taipei, Chen Chieh-jen (1960) es un videoartista cuya obra presenta una profunda y feroz – aunque a menudo silenciosa – meditación histórica y política. Sus obras se caracterizan por la inserción de imágenes de archivo que se relacionan y dialogan con imágenes contemporáneas. Mirando el pasado de China en relación con su presente, Chen subraya las consecuencias sociales, las expectativas frustradas, las interpretaciones erróneas y las apropiaciones de la mirada occidental. En particular, este estudio aborda un vídeo realizado en 2002, “Lingchi - Echoes of a historical photograph” y otro, “Factory”, realizado en 2003 que revelan el foco principal y la praxis visual y auditiva del artista. En la obra de Chen, de hecho, la visión y, sobre todo, sus límites, tanto en el sentido concreto como en el metafórico, juegan un papel importante en la construcción de un denso discurso artístico y conceptual relacionado con la creación de imágenes y la traducción visual.Born in Taiwan and currently living in Taipei, Chen Chieh-jen (1960) is a video-artist whose oeuvre presents a profound and fierce – although often silent – historical and political meditation. His works are characterized by the insertion of archival footage in close dialogue with actual and contemporary images. Looking at China’s past in relation to its present, Chen underlines social damages, frustrated expectations, misinterpretations and appropriations by the Western gaze. In particular, this study addresses a video made in 2002, “Lingchi - Echoes of a historical photograph”, and “Factory” realized in 2003; having as a mainfocus the artist’s visual and aural praxis. In Chen’s work in fact, vision, and most of all its limits, in both a concrete and metaphorical sense, play a major part in the construction of a dense artistic and conceptual discourse related to image-making and visual translation.

    The proton spin decomposition : path dependence and gauge symmetry

    Full text link
    We discuss the different types of decomposition of the proton spin. We stress that, despite their lack of uniqueness, the Chen et al. and Wakamatsu decompositions are perfectly measurable. We argue that a large part of the recent controversies boils down to the fact that there actually exist two types of gauge transformations in the Chen et al. approach, where physical and gauge degrees of freedom of the gauge potential are explicitly separated. By carefully distinguishing these two types of gauge transformations, one can easily understand how the concepts of gauge invariance, Stueckelberg symmetry, path dependence and measurability are linked to each other.Comment: 9 pages, contribution to the proceedings of the QCD Evolution 2013, May 6-10, JLab, Newport News, US
