Part of these notes have been extracted from [10] and hence have benefited from in-depth discussions with Pavel Shvaiko. Other parts of them are results from Antoine Zimmermann’s PhD dissertation [19]. And now much of them is original.

The article deals with the analysis of features Antoine Watteau's work, carried out on his painting "Harlequin and Columbine" film "The Secrets Life Watteau".

Temperature dependence of the Kováts retention index (I) was measured for some aliphatic ketones and aldehydes on a poly(dimethyl siloxane) (HP-1) stationary phase. An interesting minimum (non-linearity) was observed for the I versus isothermal column temperature (T) relationships. A novel empirical model is proposed: I=A+B/T+C ln T, where A, B and Care equation constants and B/C = T(min). A de...
