    Large-scale Coronal Heating, Clustering of Coronal Bright Points, and Concentration of Magnetic Flux (1999)
    Springer
    Space science reviews 87 (1999), S. 181-184 
    Details
    ISSN: 1572-9672
    Keywords: coronal heating ; magnetic network ; coronal bright points
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract By combining quiet-region Fe XII coronal images from SOHO/EIT with magnetograms from NSO/Kitt Peak and from SOHO/MDI, we show that the population of network coronal bright points and the magnetic flux content of the network are both markedly greater under the bright half of the large-scale quiet corona than under the dim half. These results (1) support the view that the heating of the entire corona in quiet regions and coronal holes is driven by fine-scale magnetic activity (microflares, explosive events, spicules) seated low in the magnetic network, and (2) suggest that this large-scale modulation of the magnetic flux and coronal heating is a signature of giant convection cells.

    The Removal of Dye Colours from Aqueous Solutions by Adsorption on Low-cost Materials (1999)
    Springer
    Water, air & soil pollution 114 (1999), S. 423-438 
    Details
    ISSN: 1573-2932
    Keywords: dye sorption ; equilibrium isotherms ; fixed bed ; low-cost sorbents
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The ability of five low cost adsorbents – rice husk, cotton, bark, hair and coal – to adsorb two basic dyes, namely, Safranine and Methylene Blue, has been studied. Equilibrium isotherms have been determined and analysed using the Langmuir equations. The monolayer saturation capacities for Safranine are 1119, 838, 875, 190 and 120 mg g-1adsorbent and for Methylene Blue are 914, 312, 277, 158 and 250 mg g-1adsorbent for bark, rice husk, cotton waste, hair and coal respectively. A limited number of fixed bed column studies have been performed and the bed depth service time for each dye-adsorbent system has been determined.
