    • Dusty discs in AGN 

      Efstathiou, Andreas (1996-01-01)
      A modified version of the code of Efstathiou and Rowan-Robinson (1990), that solves accurately the axially symmetric radiative transfer problem in dust clouds, is used to model the infrared emission from dust in Active ...
    • Polarimetry and the torus 

      James H. Hough, James; Young, Stuart; Efstathiou, Andreas (1996-01-01)
      While the torus plays an obvious role in blocking direct light, and thus increasing the observed polarization from scattering, its role in directly producing polarized flux is less clear. Contributions to the infrared ...

      Katbamna, Bharti; Thodi, Chryssoula D.; Senturia, Jerome B. (1996-01-01)
      This study examined auditory-evoked brainstem responses (ABR) in the deermouse (Peromyscus maniculatus) during torpor and arousal. The ABR of the euthermic deermouse consisted of five waves occurring in a time frame of 10 ...
