QUES: The Federal Constitution adopted in 1848 is the legal foundation of the modern federal state. It is among the oldest constitutions in the world. A new Constitution was adopted in 1999, but did not introduce notable changes to the federal structure. It outlines basic and political rights of individuals and citizen participation in public affairs, divides the powers between the Confederation and the cantons and defines federal jurisdiction and authority. There are three main governing bodies on the federal level: the bicameral parliament (legislative), the Federal Council (executive) and the Federal Court (judicial).

QUES: These areas, quartiers sensibles ("sensitive quarters"), are in northern and eastern Paris, namely around its Goutte d'Or and Belleville neighbourhoods. To the north of the city they are grouped mainly in the Seine-Saint-Denis department, and to a lesser extreme to the east in the Val-d'Oise department. Other difficult areas are located in the Seine valley, in Évry et Corbeil-Essonnes (Essonne), in Mureaux, Mantes-la-Jolie (Yvelines), and scattered among social housing districts created by Delouvrier's 1961 "ville nouvelle" political initiative.

QUES: This method involves coating LEDs of one color (mostly blue LEDs made of InGaN) with phosphors of different colors to form white light; the resultant LEDs are called phosphor-based or phosphor-converted white LEDs (pcLEDs). A fraction of the blue light undergoes the Stokes shift being transformed from shorter wavelengths to longer. Depending on the color of the original LED, phosphors of different colors can be employed. If several phosphor layers of distinct colors are applied, the emitted spectrum is broadened, effectively raising the color rendering index (CRI) value of a given LED.

 What shift does non-blue light undergo in the pcLEDs method?
