Steam treatment of tissue sections in citrate buffer at pH 6.0 did not increase the polariscopic refractivity of the organism. |
|
In order to do this, it was necessary to agree the relevant propagation zone type and refractivity gradients for the applicable time percentages. |
|
Zircon also has very pronounced birefringence or double refractivity, where the difference between the two refractive indices is unusually high. |
|
Some of the simpler techniques are based on the optical properties of proteins refractivity, absorption of light of different wavelengths, rotation of the plane polarized light at different wavelengths, and luminescence. |
|
The method is based on the fact that both refractive index and density are composition dependent factors that display a linear relationship to each other where the constant is called the refractivity intercept ri. |
