Formulae braces

Enclosing Marks. Where it is necessary in an inorganic formula, enclosing marks (parentheses, braces, and brackets) are nested within square brackets as follows ... 

Unstayed flat heads and covers can be designed by very specific rules and formulas given in this subsection. The stresses caused by pressure on these members are bending stresses, and the formulas include an allowance for additional edge moments induced when the head, cover, or blind flange is attached By bolts. Rules are provided for quick-opening closures because of the risk of incomplete attachment or opening while the vessel is pressurized. Rules for braced and stayed surfaces are also provided. 

A preliminary design for each members will be accomplished through the use of required resistance formulas then check for response to time dependent toads. Final design would require evaluation of connections, bracing and other items which would prevent the members from reaching their plastic capacity. 

Figure 18 shows an example of a singular system when the water-gas-shift reaction takes place adiabatically. The braces mean the mixture and the quotation marks over the reaction formula shows that this reaction is the target of this process system. 

In the same way that a worksheet formula can contain a simple constant, e.g., the value 3 in the formula =3 A1+A2, an array formula can contain an array constant. An array constant is included in a formula by enclosing the array of values in braces. In this case you must type the braces. When you enter the completed array formula by pressing CONTROL+SHIFT+ENTER, Excel automatically provides braces around the whole formula. 

To edit an array formula, simply select any cell in the array. Then edit the formula in the formula bar. When you begin to edit, the braces surrounding the formula will disappear. To re-enter the edited formula, press CONTROL+SHIFT+ENTER. The formula will be entered into all of the cells originally selected for the array. 

To use a worksheet formula that returns an array result, you must first select a suitable range of cells, with dimensions (R x C) large enough to accommodate the returned array, then type the formula in the formula bar, and finally enter the formula by pressing CONTROL+SHIFT+ENTER. Excel will indicate that the formula is an array formula by enclosing it in braces and will enter the array formula in all the selected cells. 

In formulae, these enclosing marks are used in the following nesting order [],[()],[ () ], [( () )], [ ( () ) ], etc. Square brackets are normally used only to enclose entire formulae parentheses and braces are then used alternately (see also Sections IR-4.2.3 and IR-9.2.3.2). There are, however, some specific uses of square brackets in formulae, cf. Section IR-2.2.2.1. 

Braces are used in names and formulae within the hierarchical sequence outlined and exemplified in Section IR-2.2.1. 

The formula for the entire coordination entity, whether charged or not, is enclosed in square brackets. When ligands are polyatomic, their formulae are enclosed in parentheses. Ligand abbreviations are also usually enclosed in parentheses. The nesting order of enclosing marks is as given in Sections IR-2.2 and IR-4.2.3. Square brackets are used only to enclose coordination entities, and parentheses and braces are nested alternately. 

One should note that Wurtz was still using conventional equivalents, so that it is necessary to halve the number of oxygen and carbon atoms in order to translate this formula into a Williamsonian atomic weight formula. But similar to Williamson, one sees no brackets, braces, buckles, parentheses, or punctuation. As with Williamson s formulas, Wurtz expressed his ideas about the constitution of a molecule solely by the spatial relationships of the letters that symbolize the atoms it contains. 

At the CTst stage of the given process, reaction described by general Equation (1), takes place (in the braces formulas of gelatin-immobilized chemical compounds have been indicated) ... 

From the polynomial regression equation, y = 0.0006x - 0.0722x + 2.88Sx -19.292, it is possible to calculate the percentage reduction in circumference required when producing a brace. These values are illustrated on Table 6[d] and can be conqxired with actual values calculated from the formulae. 

The coordinations are written as Roman superscript prefixes to the atom symbols in the compound formula. Also, to distinguish between formulas for compounds and formulas for coordination figures, in the latter case the symbol for the coordinated atom is enclosed in braces... 

Parentheses changing the order of operations 2 + 2 2 = 6 but (2-1-2) 2 = 8. It is recommended that a user types the left parenthesis ( followed by a right one ) and then moves a cursor left to one position and enters the required expression. Thus, we can control the number of initial and close parentheses in the expression (formula). one cannot enter brackets and braces. 

Nitinol is a nickel-titanium alloy known as memory metal. The name nitinol is derived from the s)mnbols for nickel (Ni), titanium (Ti), and the acronym for the Naval Ordinance Laboratory (NOL), where it was discovered. If an object made out of nitinol is heated to about 500 °C for about an hour and then allowed to cool, the original shape of the object is "remembered," even if the object is deformed into a different shape. The original shape can be restored by heating the metal. Because of this property, nitinol has found many uses, especially in medicine and orthodontics (for braces). Nitinol exists in a number of different solid phases. In the so-called aus-terite phase, the metal is relatively soft and elastic. The crystal structure for the austerite phase can be described as a simple cubic lattice of Ti atoms with Ni atoms occupying cubic holes in the lattice of Ti atoms. What is the empirical formula of nitinol and what is the percent by mass of titanium in the alloy ...
