A Serra Pelada é uma localidade brasileira, vila e distrito do município de Curionópolis, no sudeste do Pará. Por fusão de significados, a vila e o distrito tomaram o mesmo nome de uma formação geológica rica em metais preciosos, a colina de Serra Pelada, uma extensão da Serra dos Carajás. Wikipédia

"Oh father, he meant no ill will."

Rukia looks cool...but she will never be hot, to me... My older sister looked JUST like rukia, BEFORE BLEACH EVEN CAME TO AMERICA!!! I was watching Anima before my sister, too!! So...whenever I see rukia, all I ever see is my sister. It creeps me out whenever there are any scenes where rukia is either half naked or even implied perversion [shutters and shivers] I feel like I wanna just rip off my dong, lol! Ane-san...WWWHHYYYYY!?!?!?!? DX It's a good thing Rukia and ichigo never get together. My sister always said I remind her of ichigo. Her boyfriend is renji. Our mother is Rangiku, in more ways than one. [Holds back vomit]. Our step father is a mix up of the head captain and byakuya. And finally, our cat was yoruichi, lol!luiz o engano

∗54.43.⊢((α,β∈1)⊃((α∩β=Λ)≡(α∪β∈2)))
.
The ⊢ symbol has not changed; it means that the formula to which it applies is asserted to be true. ⊃ is logical implication, and ≡ is logical equivalence. Λ is the empty set, which we write nowadays as ∅. ∩ ∪ and ∈ have their modern meanings: ∩ and ∪ are the set intersection and the union operators, and x∈y means that x is an element of set y.

The remaining points are semantic. α and β are sets. 1 denotes the set of all sets that have exactly one element. That is, it's the set { c : there exists a such that c = { a } }. Theorems about 1 include, for example:

that Λ∉1 (∗52.21),
that if α∈1 then there is some x such that α = {x} (∗52.1), and
that {x}∈1 (∗52.22).
2 is similarly the set of all sets that have exactly two elements. An important theorem about 2 is ∗54.3, which says
∗54.3.⊢2=α^{(∃x).x∈α.α−ι‘x∈1}.
