Yellowcake (also called urania) is a kind of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium ores. Yellowcake concentrates are prepared by various extraction and refining methods, depending on the types of ores. Typically, yellowcakes are obtained through the milling and chemical processing of uranium ore forming a coarse powder which has a pungent odor, is insoluble in water and contains about 80% uranium oxide, which melts at approximately 2878 °C.
The ore is first crushed to a fine powder by passing raw uranium ore through crushers and grinders to produce "pulped" ore. This is further processed with concentrated acid, alkaline, or peroxide solutions to leach out the uranium. Yellowcake is what remains after drying and filtering. The yellowcake produced by most modern mills is actually brown or black, not yellow; the name comes from the color and texture of the concentrates produced by early mining operations.
Initially, the compounds formed in yellowcakes were not identified; in 1970, the U.S. Bureau of Mines still referred to yellowcakes as the final precipitate formed in the milling process and considered it to be ammonium diuranate or sodium diuranate. The compositions were variable and depended upon the leachant and subsequent precipitating conditions. Among the compounds identified in yellowcakes include: uranyl hydroxide, uranyl sulfate, sodium para-uranate, and uranyl peroxide, along with various uranium oxides. Modern yellowcake typically contains 70 to 90 percent triuranium octoxide (U3O8) by weight. Other oxides such as uranium dioxide (UO2) and uranium trioxide (UO3) exist.
Martha Stewart (née Kostyra; August 3, 1941) is an American business magnate, author, magazine publisher, and television personality. As founder of Martha Stewart Living Omnimedia, she has gained success through a variety of business ventures, encompassing publishing, broadcasting, merchandising, and electronic commerce. She has written numerous bestselling books, is the publisher of the Martha Stewart Living magazine, and her syndicated talk show, Martha, is broadcast throughout the world.
In 2004, Stewart was entangled in the ImClone insider trading affair and there was speculation that the incident would effectively be the end of her media empire. She began a comeback campaign in 2005 and her company returned to profitability in 2006. Stewart rejoined the board of directors of Martha Stewart Living Omnimedia in 2011 and became chairman of her namesake company again in 2012.
Martha Stewart was born in Jersey City, New Jersey to middle-class Polish American parents, Edward "Eddie" Kostyra (c. 1912 – 1979) and Jadwiga Martha Ruszkowski Kostyra (b. September 16, 1914, Buffalo, New York – d. November 16, 2007, Norwalk, Connecticut). She lived in Jersey City until the age of 3, when her family moved to Nutley. She was raised in Nutley along with her five siblings. She took the name "Grace" for her confirmation name before graduating from Nutley High School.

Une tonne de poudre sur le marcher
On va la moudre, la mélanger
A des enzymes ammoniaquées
De la farine et des saletés
Quand son volume aura triplé
On va pouvoir la reffourguer
A tous les toxicos ridés
Qui ne demandent qu'à s'évader
Des tonnes de poudre sur Paris
Seront vendues sévices compris,
Dans les veines ou dans les naseaux
Pour s'ammoniaquer les tuyaux.
T'achètes 1 gramme de coco
Ça te coûte la peau et les os
C' qu'y a dedans, tu sais pas trop,
Tu te fais mener en bateau...
Une tonne de schitt sur Toulouse,
Certes, il faudra bien moins de flouze
Sache que les feuilles et le carton
Sont pas fourni par la maison
A l'huile de vidange, au henné
Tous les parfums sont proposés
En de savant "cocktails Danger"
Que les dealers gardent secrets
Tous ces mineurs de fond pourris
S'attaquent à ton anatomie
Ton sang deviendra eau usée
Ton cerveau pâte à colmater
3 tonnes de schitt à consumer
Il te faudra bien des briquets
Avant de pouvoir distinguer
A quelle sauce tu te fais bouffer
Tous ces dealers qui s'enrichissent
Te feraient boire même de la pisse
En te disant que c'est le jus
D'une herbe rare d'Honolulu !
Mais laisse donc la merde là où elle est
Mieux vaut voyager pour de vrai !
Y'a une ville pas très loin
Où l'herbe pousse en magasins
On la visite sur des vélos,
Y'a un quartier rouge, des canaux
Tu peux rouler en liberté
