      Newman, Dina; Hoffjan, Sabine; Bourgain, Catherine; Abney, Mark; Nicolae, Raluca; Profits, Elle; Grow, Michael; Walker, Karen; Steiner, Lori; Parry, Rodney; Reynolds, Rebecca; McPeek, Mary; Cheng, Suzanne; Ober, Carole (Nature Publishing Group: European Journal of Human Genetics, 2004-07)
      Founder populations have been the subjects of complex disease studies because of their decreased genetic heterogeneity, increased linkage disequilibrium and more homogeneous environmental exposures. However, it is possible ...
    • Aspects of ecosystem persistence and the optimal conservation of species 

      Batabyal, Amitrajeet (Elsevier. The definitive version can be found at http://www.elsevier.com, 2000)
      Although ecologists have long recognized the salience of persistence in determining the static and the dynamic behavior of ecological systems, it is only very recently that economists have begun to study this concept in ...

      Carefully controlled and calibrated experiments indicate a maximum capacity for adsorption of hydrogen on SWNTs is ~8 wt% under room temperature and pressure conditions. Samples displaying this maximum value were prepared ...
    • Asymptotic effectiveness – NTU formulas for multipass plate heat exchangers 

      Kandlikar, Satish; Shah, Ramesh (Journal of heat transfer - ASME, 1989)
      The effectiveness of a plate heat exchanger with finite number of plates is affected by the end channels, and the channels between two adjacent passes. these effects become less significant as the number of plates becomes ...

      Photoabsorption spectra of gaseous ethyl nitrate, n-propyl nitrate, 2-propyl nitrate, n-butyl nitrate and 3-methyl-1-butyl nitrate were quantitatively measured in the laboratory at room temperature for λ >185 nm. The spectra ...
    • Atmospheric photodissociation lifetimes for nitromethane, methyl nitrite, and methyl nitrate 

      Taylor, W.; Allston, T.; Moscato, M.; Fazekas, G.; Kozlowski, R.; Takacs, Gerald (Wiley: International Journal of Chemical Kinetics, 1980-04)
      Atmospheric photodissociation rate coefficients and photodissociation lifetimes for nitromethane, methyl nitrite, and methyl nitrate were calculated as a function of altitude from their measured visible and near ultraviolet ...
    • Atomic structure of the DNA repair [4Fe-4S] enzyme endonuclease III 

      Kuo, C.; McRee, D.; Fisher, C.; O'Handley, Suzanne; Cunningham, R.; Tainer, J. (American Association for the Advancement of Science: Science, 1992-10-16)
      The crystal structure of the DNA repair enzyme endonuclease III, which recognizes and cleaves DNA at damaged bases, has been solved to 2.0 angstrom resolution with an R factor of 0.185. This iron-sulfur [4Fe-4S] enzyme is ...
    • ATP-Dependent colchicine transport by human erythrocyte glutathione conjugate transporter 

      Awasthi, S.; Singhal, S.; Pandya, U.; Gopal, Shuba; Zimniak, P.; Singh, S.; Awasthi, Y. (Elsevier: Toxicology and Applied Pharmacology, 1999-03)
      We have recently demonstrated mutually inhibitory ATP-dependent transport of dinitrophenyl-S-glutathione (DNP-SG) and doxorubicin by DNP-SG ATPase purified from human erythrocyte membranes (S. Awasthi et al., 1998a,b). Our ...
    • Attractive interactions in micelles and microemulsions 

      Huang, John; Saffran, Samuel; Grest, Gary; Kotlarchyk, Michael; Quirke, Nick (American Physical Society, 1984-08-06)
      We have used small-angle neutron scattering to study surfactant interactions in an inverted micellar and a related microemulsions system. The structure-factor fits imply an attractive interaction between micelles with a ...
