Morning dressMorning dress, also known as formal day dress, is the formal Western dress code for day attire, consisting chiefly of, for men, a morning coat, waistcoat, and formal trousers, and an appropriate gown for women. Men may also wear a popular variant where all parts (morning coat, waistcoat and trousers) are the same colour and material, often grey and usually called "morning suit" or "morning grey" to distinguish it; considered properly appropriate only to festive functions such as summer weddings and horse races, which consequently makes it slightly less formal.
ActiniumL’actinium est un élément chimique de la famille des actinides, de symbole Ac et de numéro atomique 89. Son nom vient du grec ancien , « rayon de soleil », évoquant le caractère lumineux de cet élément. L’actinium a été découvert par André-Louis Debierne en 1899 dans des mélanges d’oxydes de terres rares. Le corps simple actinium est un métal blanc argenté et mou. On l’extrait en petites quantités des minerais d’uranium (c’est un produit de la chaîne de désintégration de U) ou par réaction nucléaire.
