Research shows that while several species of Pacific salmon can be carriers of the virus, even highly pathogenic strains, Pacific salmon currently show high relative resistance and no ISAV-related symptoms.

Grace and Nevin ( 1997 ) assessed both relative resistance to change in a multiple schedule and preference in a concurrent-chains procedure with pigeons pecking lighted disks for food reinforcement.
13.
Thus, Equation 2 states that relative resistance to change is a power function of the relative rate of reinforcement across stimulus contexts, with the " a " parameter indicating sensitivity to relative reinforcement rate.
14.
When the relative rate of reinforcement was manipulated identically and simultaneously across stimulus contexts in the multiple schedule and concurrent-chains procedure, both relative resistance to change and preference was greater with richer contexts of reinforcement.
15.
Wrought wire definitive palatal lift prosthesis clasps have an advantage over cast metallic definitive palatal lift prosthesis clasps by virtue of their relative resistance to work hardening that can contribute to the fracturing of cast clasps.
16.
Immature maize shoots accumulate a powerful antibiotic substance, DIMBOA that serves as a natural defense against a wide range of pests and is also responsible for the relative resistance of immature maize to the European corn borer.

When informed by an interviewer, in 1974, that the pillar was not in fact rust-free, and that its origin, method of construction, and relative resistance to corrosion were all well understood, D�niken responded that he no longer believed extraterrestrials had been involved in its creation.

Almost every detailed description of the Romney cites relative resistance to foot rot, an attribute rarely mentioned in descriptions of other breeds . It is said that foot rot and liver fluke seldom affect Romney Marsh sheep . reads a 1918 American text.
19.
Also, it is unclear what factors affect relative resistance to change of responding maintained by conditioned reinforcement ( Shahan & Podlesnik, 2005 ) or two concurrently available responses when different rates of reinforcement are arranged within the same context for those responses ( e . g ., Bell & Williams, 2002 ).

A quality U-lock will advertise the material's hardness ( relative resistance to grinding ), its resistance to prying ( expressed in tonnes, or pounds, for example, one might resist to 5 tonnes, which exceeds the 2-tonne capacity of a common car jack ), as well as resistance to drilling into the keyhole itself.
