We review theoretical models to show that contrast reduction at a specific wavelength in the horizontal direction depends directly on the beam attenuation coefficient at that wavelength. If a black target is used, the inherent contrast is always negative unity, so that the visibility of a black target in the...
The pharmacokinetics and dose proportionality of ibuprofen were examined in African and Asian elephants after single dose administration of 4, 5 and 6 mg/kg and on multiple dose administration. Each elephant received all the three doses and plasma ibuprofen concentrations were measured by HPLC. Approximate linearity of ibuprofen pharmacokinetics in...
