Bronchoalveolar lavage (BAL) fluid analysis was performed to determine whether the sympathetic nervous system and T cells were key sources of catecholamines in current models of lung injury. Peak levels of adrenaline occurred in BAL fluids 2 h after the initiation of immune-complex-mediated injury (Fig. 4e).
An example to show covariance estimation with the Mahalanobis distances on Gaussian distributed data. For Gaussian distributed data, the distance of an observation to the mode of the distribution can be computed using its Mahalanobis distance: where and are the location and the covariance of the underlying Gaussian distribution. In practice, and are replaced by some estimates.
To calculate the distance between scale models of. Earth and the Moon. Background. As long as people have looked at the Moon, they have wondered how far away it is. from Earth. The average distance to the Moon is 382,500 km. The distance varies. because the Moon travels around Earth in an elliptical orbit. At perigee, the point at. which the Moon is closest to Earth, the distance is approximately 360,000 km.
