Context: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.

For every element x of a poset it is trivially true (it is a vacuous truth) that ∀ a ∈ ∅ : x ≤ a (\displaystyle \forall a\in \varnothing :x\leq a) and ∀ a ∈ ∅ : a ≤ x (\displaystyle \forall a\in \varnothing :a\leq x) , and therefore every element of a poset is both an upper bound and a lower bound of the empty set. This implies that the join of an empty set is the least element ⋁ ∅ = 0 (\displaystyle \bigvee \varnothing =0) , and the meet of the empty set is the greatest element ⋀ ∅ = 1 (\displaystyle \bigwedge \varnothing =1) . This is consistent with the associativity and commutativity of meet and join: the join of a union of finite sets is equal to the join of the joins of the sets, and dually, the meet of a union of finite sets is equal to the meet of the meets of the sets, i.e., for finite subsets A and B of a poset L,

It does not include decisions that have been abrogated by subsequent constitutional amendment or by subsequent amending statutes.

In chickens it is formed from the layers of secretions of the anterior section of the hen's oviduct during the passage of the egg. It forms around fertilized or unfertilized egg yolks. The primary natural purpose of egg white is to protect the yolk and provide additional nutrition for the growth of the embryo (when fertilized). Egg white consists primarily of about 90% water into which is dissolved about 10% proteins (including albumins, mucoproteins, and globulins). Unlike the yolk, which is high in lipids (fats), egg white contains almost no fat, and carbohydrate content is less than 1%. Egg whites contain about 56% of the protein in the egg. Egg white has many uses in food (e.g. meringue, mousse) and also many other uses (e.g. in the preparation of vaccines such as those for influenza).
