How does the amount of each pigment explain why leaves are certain colours? What is the importance of rinsing the pH electrode after each sample? Explain the difference between a cationic dye and an anionic dye in terms of cell staining. ...
The time-scale of colour/pH changes in the caeca of 196 longfinned squid Loligo vulgaris reynauclii during digestion/absorption was tested at sea. Red, brown, dark yellow, pale yellow and white were the recorded colours. The range of mean pH for these colours was 6,0195,638. The time-...
change. Battery-powered portable pH meters are widely used for field tests of the pH of soils. Tests of pH may also be performed, less accurately, withlitmuspaper or by mixing indicator dyes in liquid suspensions and matching the resulting colours against a colour chart calibrated in pH. In ...
ThemCP indicator dye was obtained as a sodium salt (Acros Organics). The indicator was purified using the preparative HPLC procedure described in Liuet al.31using a Shimadzu HPLC system. In preparative mode, the system consisted of a system controller (SCL-10Avp), a preparative scale pump (LC...
Colours in scatterplots for hierarchical predictions indicate weights used to combine Ỹa(s) and Ỹc(s) predictions according to Eq. (6). Bottom row displays density plots of observed validation data (solid black line), predictions computed for the validation locations (dotted yellow line)...
(14)) that relates the colour hue to the pH value and illustrates how the colour hue values vary across different pH levels. The hue values of the captured colours range from about 20 for pH values below 4 to about 260 for pH values above 10. The function demonstrates a useful range ...
What colours do the following indicators turn when added to an acid (such as hydrochloric acid)? (a). Litmus (b). Methyl orange View Solution A beaker of concentrated hydrochloric acid has a pH of 1. What colour will full range universal indicator turn if it is added to this beaker? Is...
(Degree priority law) Given a node v ∈ V, we defined the length of degrees of v to be the number of colours associated with all the neighbours of v, written by l(v). For j ≤ l(v), we defined the j-th degree of v to be the j-th largest number of edges of the...

I was challenged on the London/Decca pressing myth. A member claimed that Londons weighed less to save on shipping—proof that they were not identical. So I weighed a few London and Decca titles on a digital scale. All weighed within a few grams of each other. Some of the Londons weig...
