Ship's A.I. was created untold millennia ago by the Celestials as the operating system for a data collection device. The Celestials had genetically manipulated humanity, and they left the Ship in the area that would come to be known as Mongolia to monitor humanity's progress.
Circa 1100 A.D., a Mongolian immortal known as Garbha-Hsien (later known as Saul), discovered the Ship and lived next to it while he researched its mysteries. Saul never attempted to enter the Ship.
In time, the Egyptian immortal En Sabah Nur learned of Saul and sought him out as another immortal. In a confrontation, En Sabah Nur slew all of Saul's guards. Saul then sought to humble his fellow "forever-walker" by revealing the secret titanic vessel. Having had previous experience with futuristic technology due to his encounters with Rama-Tut, Nur attacked Saul and left the other immortal for dead and entered the Ship. He emerged later as a vastly changed being who now called himself Apocalypse.
Phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase (EC188.8.131.52, SHIP1, SHIP2, SHIP, p150Ship) is an enzyme with system name 1-phosphatidyl-1D-myo-inositol-3,4,5-trisphosphate 5-phosphohydrolase. This enzyme catalyses the following chemical reaction
This enzyme hydroylses 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3) to produce PtdIns(3,4)P2.
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering. They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S — selectivity).
There are conflicting definitions in the literature for selectivity and yield, so each author's intended definition should be verified.
Conversion can be defined for (semi-)batch and continuous reactors and as instantaneous and overall conversion.
The following assumptions are made:
The following chemical reaction takes place:
where and are the stoichiometric coefficients. For multiple parallel reactions, the definitions can also be applied, either per reaction or using the limiting reaction.
Batch reaction assumes all reactants are added at the beginning.
In logic, the converse of a categorical or implicational statement is the result of reversing its two parts. For the implicationP→Q, the converse is Q→P. For the categorical propositionAll S is P, the converse is All P is S. In neither case does the converse necessarily follow from the original statement. The categorical converse of a statement is contrasted with the contrapositive and the obverse.
Let S be a statement of the form P implies Q (P→Q). Then the converse of S is the statement Q implies P (Q→P). In general, the verity of S says nothing about the verity of its converse, unless the antecedentP and the consequentQ are logically equivalent.
For example, consider the true statement "If I am a human, then I am mortal." The converse of that statement is "If I am mortal, then I am a human," which is not necessarily true.
On the other hand, the converse of a statement with mutually inclusive terms remains true, given the truth of the original proposition. Thus, the statement "If I am a bachelor, then I am an unmarried man" is logically equivalent to "If I am an unmarried man, then I am a bachelor."
