Binaural room impulse responses (BRIRs) were measured in a classroom for sources at different azimuths and distances (up to 1 m) relative to a manikin located in four positions in a classroom. When the listener is far from all walls, reverberant energy distorts signal magnitude and phase independently at each frequency, altering monaural spectral cues,(More)
Estrogen prevents osteoporotic bone loss by attenuating bone resorption; however, the molecular basis for this is unknown. Here, we report a critical role for the osteoclastic estrogen receptor alpha (ERalpha) in mediating estrogen-dependent bone maintenance in female mice. We selectively ablated ERalpha in differentiated osteoclasts(More)
SUMMARY Estrogen prevents osteoporotic bone loss by attenuating bone resorption; however, the molecular basis for this is unknown. Here, we report a critical role for the osteoclastic estro-gen receptor a (ERa) in mediating estrogen-dependent bone maintenance in female mice. We selectively ablated ERa in differentiated osteoclasts (ERa DOc/DOc) and found(More)
The behavioral effects of cannabinoids are dependent upon numerous variables which include species differences, dose, experimental conditions, etc. The complexity of the cannabinoid behavioral syndrome certainly complicates attempts to establish biochemical correlates. It is for this reason that attempts are being made to develop analogs that exhibit(More)
The nature of mecamylamine's and pempidine's antagonism of nicotine in the central nervous system has not been defined clearly. Although these compounds are thought to be noncompetitive antagonists in the brain due to the fact that they do not compete effectively for agonist binding to brain tissue in vitro, pharmacological evidence is lacking. The(More)
An algorithm has been developed for the non-destructive determination of local thickness of the refractory material walls in smelter furnaces. This method uses measurements of temperature and heat flux at a number of points on the outer (fixed) surface of the furnace and assumes that the inner (guessed) surface of the furnace wall is isothermal. The(More)
The MILAGRO field campaign was a multi-agency international collaborative project to evaluate the regional impacts of the Mexico City air pollution plume as a means of understanding urban impacts on the global climate. Mexico City lies on an elevated plateau with mountains on three sides and has complex mountain and surface-driven 5 wind flows. This paper(More)
