However, it is not clear why does boric acid additive improve the dichromatic performance of the polarizer based on this film and what chemical structures are formed between the intermolecular PVA chains, although the various reaction schemes and the chemical structural models have been proposed for understanding the role of boric acid in the production of the polarizers [28-30].

The cells were then washed with cold PBS and treated with 10 [micro]l of staining solution containing acridine orange (100[micro]l/ml) and ethidium bromide (80[micro]l/ml) and immediately observed under fluorescence microscope (Leica Fluorescence microscope) at magnification of 40 x, excitation range-blue, excitation filter-BP450-490, dichromatic mirror-510 and suppression filter-LP515.
Many color-deficient individuals have dichromatic vision in that only some of the colors are visible (refer to Rigden (1999) or Hess (2000) for an in-depth explanation).
The main plant recognition methods are : gaussian distribution models; near infrared images; texture ; shape features; spectral properties of reflection; spatial frequency based properties; dichromatic reflection model; other wavebands; RGB (red, green, blue) colour model; HSV(hue, saturation, value) colour space; YCrCb colour space (Klose et al, 2005); Grey Level Co-occurrence Matrix (GLCM); Fast Fourier Transform (FFT); Scale Invariant Feature Transform (SIFT); binarization; EGRBI transform (Excessive Green, RedBlue, Intensity) (Maksimow et al, 2007); Minimum Distance Function (MDF); clustering; seed mapping.
He reviews classical probability problems and presents dichromatic Polya urns as a basic structure that grows in discrete time, then applies the discrete Polya urn structure to Poisson and the depoissonization heuristic, urn schemes with random replacement, and analytic urns.
