Apostrophes

Hakchen, n. little hook, booklet, clasp, catch apostrophe. 

From here on, we will omit the apostrophe ( ) where it would not cause confusion, as it goes without saying that we work with deviation variables. We now further rewrite the same equation as... 

Are there more manipulated forms of the same old heat balance You bet. In fact, we very often rearrange Eq. (2-48), writing without the apostrophes, as... 

Let us try one simple example. Say if we keep the inlet temperature constant at our desired steady state, the statement in deviation variable (without the apostrophe) is... 

Here, we model the flow through the valves with resistances R and R2, both of which are constants. We rearrange the balance equations a bit, and because both equations are linear, we can quickly rewrite them in deviation variables (without the apostrophes) ... 

Since q and c0 are input functions, the linearized equations in deviation initial conditions are (with all apostrophes omitted in the notations) ... 

Now we linearize the two equations about the steady state. We expect to arrive at (with the apostrophes dropped from all the deviation variables and partial derivatives evaluated at the steady state) ... 

Jacobus van t Hoff was a Dutch scientist (1852-1911). Notice the peculiar arrangement of the apostrophe, and small and capital letters in his surname. 

Apostrophes are used to indicate ownership. Eight rules cover all of the situations in which they may appear. 

Possessive plural nouns already ending in 5 need only the apostrophe added ... 

Possessive pronouns never have apostrophes, even though some may end in s ... 

Apostrophes form contractions by taking the place of the missing letter or number. Do not use contractions in highly formal written presentations ... 

Unlike most possessives, its does not contain an apostrophe. The word it s is instead a contraction of the words it is. The second i is removed, and replaced by an apostrophe. 

When revising your writing, say the words it is when you come across it s or its. If they make sense, you should be using the contraction. If they don t, you need the possessive form, its, without an apostrophe. 

Hint Unlike most possessives, it doesn t have an apostrophe. ... 

Mechanics Rules for spelling and standard punctuation (including the use of apostrophes, hyphens, and capitalization). 

Rule 10 Form the plural of multiple-letter, all-capital abbreviations and abbreviations ending in a capital letter by adding a lowercase s only. Do not put an apostrophe before the s do not add an s to units of measure ... 

Imagine that the apostrophe in they re is actually a very small letter a. Use they re in a sentence only when you can substitute they are. 

Apostrophes are used to form contractions, indicate ownership, and form certain plurals. Review these six rules for their use. 

CEO s needs an apostrophe to show possession, accounts does not need an apostrophe (it is merely plural), and companies is not plural but singular, and also needs an apostrophe to show possession. The only choice that corrects all three errors is e. 

For a given geometry of the set-up, the relevance list for this problem contains the power consumption, P, as the target quantity, the stirrer diameter, d, as the characteristic length and a number of physical properties of the liquid and the gas (the latter are marked with an apostrophe) Densities, p and p, kinematic viscosities, v and v, surface tension, a, and an unknown number of still unknown physical properties, S, which describe the coalescence behaviour of finely dispersed gas bubbles and by this, indirectly, their hold-up in the liquid. The process parameters are the stirrer speed, n, and the gas throughput, q, which can be adjusted independently, as... 

Choice b has an apostrophe error in being s. Choices c and e are fragments. 

We have the following unknown boundary values the two species nearsurface concentrations Cyo and Cb,o, the two species fluxes, respectively G and G n, the additional capacitive flux Gc, and the potential p, differing (for p > 0) from the nominal, desired potential pnom that was set, for example, in an LSV sweep or a potential step experiment. Five of the six required equations are common to all types of experiments, but the sixth (here, the first one given below) depends on the reaction. That might be a reversible reaction, in which case a form of the Nernst equation must he invoked, or a quasi-reversible reaction, in which case the Butler-Volmer equation is used (see Chap. 6 for these). Let us now assume an LSV sweep, the case of most interest in this context. The unknowns are all written as future values with apostrophes, because they must, in what follows below, be distinguished from their present counterparts, all known. 

The variables have been written without apostrophes. At the beginning of the Newton process, they have the old values, while the function F(X) supplies new constant values, driving the calculation. We demand that the corrected vector X f SX satisfies (11.17), that is, that the left-hand side of (11.19) is zero. This leaves... 

Form the possessive of a joint owner by adding an apostrophe and an s after the last name only. 

Form the possessive of plural nouns that do not end in s by adding an apostrophe and an s . Form the possessive of plural nouns that end in s by adding an apostrophe only.
