Fisher relationship

The second is using the Tully-Fisher relationship, which provides a direct relationship between the absolute luminosity of a spiral galaxy and its maximum rotation speed. Since the maximum rotation speed can be directly estimated by observation, one can estimate the absolute luminosity since we measure directly the apparent luminosity, the inverse-square law allows us to estimate the distance to the object concerned. For the present discussion, it is important to understand that, at optical wavelengths, estimates of maximum rotation speeds are generally extrapolations from rotation curve measurements. [Pg.300]

For this sample, the galactic distance scale has been set by Mathewson, Ford, and Buchhorn (MFB) using the Tully-Fisher relationship, which sets distance scales by using an observed correlation between the maximum rotation velocity of a spiral and its absolute luminosity, and so is quite distinct from Hubble-based distance determinations. Even so, the Tully-Fisher method gives an absolute scale only after calibration, and the MFB calibration gave a scale that was statistically similar to a Hubble scale using H = 85kms-1 Mpc 1. [Pg.305]

Figure 10-13 illustrates the flow versus valve stem travel characteristic for various typical valve trim functions (Fisher Controls, 1987). The quick opening characteristic provides the maximum change in flow rate at low opening or stem travel, with a fairly linear relationship. As the valve approaches the wide open position, the change in flow with travel approaches zero. This is best suited for on-off control but is... [Pg.313]

Indirect mechanisms Nicotine has indirect effects on monoamine systems. A considerable amount of research has examined the relationships between nicotine and dopamine activity in the brain, in light of dopamine s role in reinforcement and nicotine s addictive properties. Nicotine increases dopamine turnover in the striatum and cerebral cortex (Clarke and Reuben 1996 Tani et al. 1997 Nanri et al. 1998). It also increases burst activity in dopamine neurons of the ventral tegmental area (VTA), a primary source of dopamine to the forebrain (Nisell et al. 1995 Fisher et al. 1998). Such a firing pattern in the VTA is associated with processes of reinforcement, learning, and cognitive activity. Nicotine actions on dopaminergic neurons occur at both somatodendritic sites and synaptic terminals. Further, both systemic nicotine and direct administration into the VTA increase dopamine release in the nucleus ac-... [Pg.109]

Earlier it was mentioned, and demonstrated using the Fisher Iris example (Section 12.2.5), that the PCA scores (T) can be used to assess relationships between samples in a data set. Similarly, the PCA loadings (P) can be used to assess relationships between variables in a data set. For PCA, the first score vector and the first loading vector make up the first principal component (PC), which represents the most dominant source of variability in the original x data. Subsequent pairs of scores and loadings ([score vector 2, loading vector 2], [score vector 3, loading vector 3]...) correspond to the next most dominant sources of variability. [Pg.398]

Assessment of environmental and health hazards from chemicals reqnires a multidisciplinary approach. One needs to consider chemical economics, production, usage, and so on environmental release monitoring data environmental behavior health and environmental effects. Often events concerning environmental and health hazards can be predicted based on strnctnre and activity relationships and physical-chemical characteristics. The first volnme of their publication has made available current information in several important areas of chemical hazard assessment (Saxena and Fisher, 1981 Saxena, 1983 Saxena, 1984). [Pg.291]
