Procedure steps section

Ask experienced mechanics or operators to describe a simple task that they perform. You will quickly see that even simple tasks can involve many steps. The Procedure Steps section requires the greatest attention to analysis by the writer and reviewers. The section should describe, when appUcable  

Unique situations may cause you to address known process problems in the procedures. These process problems are often identified in Process Hazards Analyses. 

Before drafting a procedure, you should consider step numbering options, the content, writing style, placement of notes and cautions, branching, and use of lists, tables, illustrations, graphics, and pictures. These should be defined in your procedure management system. 

There are many options a writer can choose when numbering a procedure step. In the past, the trend was to number procedures in what is called legal 

This is a valid numbering system, but it is not friendly to the user. The main advantage is that each item has a unique number for reference. The main disadvantage is that it does not make the procedure easier to understand or to use. The extra numbers at the third or fourth level don t really give users any information that can help their performance.

The time derivative is zero at steady state, but it is included so that the method of false transients can be used. The computational procedure in Section 4.3.2 applies directly when the energy balance is given by Equation (5.28). The same basic procedure can be used for Equation (5.25). The enthalpy rather than the temperature is marched ahead as the dependent variable, and then Tout is calculated from Hout after each time step. 

The polymerization methods to PPV and PPV derivatives described in the previous section involve 1,6-polymerization of an immediately formed 1,4-xylyl-ene derivative. Aside frome this polymerization approach, a broad spectrum of polycondensation procedures (step-growth methods) to PPV and PPV derivatives has been developed. The methods can be classified as follows ... 

The converged MEPs from the combined procedure were employed as a template for our modified NEB calculations [27], The calculated MEPs for both steps of the reaction were determined with seven images for each path. In order to carry out the FEP calculation, following the procedure of Section 3.2.3, two images were added between each pair of converged images on the path. This produced overall paths with... 

It approximates the expectation of the stochastic formulation (usually called the true problem) and can be solved using deterministic algorithms. Problem (9.19) can be solved iteratively in order to provide statistical bounds on the optimality gap of the objective function value. The iterative SAA procedure steps are explained in Section 7.5 of Chapter 7. 

For one catalytic cycle, relaxation in the subspace = 0 is approximated by relaxation of a chain that is produced from the cycle by cutting the limiting step (Section 2). For reaction networks under consideration (with one cyclic attractor in auxiliary discrete dynamical system) the direct generalization works for approximation of relaxation in the subspace = 0 it is sufficient to perform the following procedures ... 

Dominant systems are acyclic. All the stationary rates in the first order are limited by limiting steps of some cycles. Those cycles are glued in the hierarchical cycle gluing procedure, and their limiting steps are deleted in the cycles surgery procedures (see Section 4.3 and Figure 1). 

Experimental Procedure. This section contains a step-by-step detailed procedure for the experiment. It is divided into logical parts for ease of completion and to facilitate the interruption of an experiment, if necessary. To enhance student awareness, an icon (El) is used to alert students and instructors to possible safety concerns. 

Combinatorial synthesis on solid supports is usually carried out by using either the parallel synthesis (see section 6.2.1) or the Furka split and mix procedures (see section 6.2.2). The precise method and approach adopted when using these methods will depend on the nature of the combinatorial library being produced and also the objectives of the investigating team. However, in all cases it is necessary to determine the structures of the components of the library by either keeping a detailed record of the steps involved in the synthesis or giving beads a label that can be decoded to give the structure of the compound attached to that bead (see section 6.3). The method adopted to identify the components of the library will depend on the nature of the synthesis. 

Test Procedure Using the BEP III Before using the BEP III, perform the sample dispensing steps (Section 1 from procedure using the BEP II ). Immediately afterwards place the uncovered test plates into the BEP III. The test is then processed fully automatically. 

When thermal equilibrium reached (i.e. after c. 3-5 hours), the dead space volume is determined as in Steps 3 and 4 of the discontinuous manometric procedure in Section 3.3.1. In the case of low-temperature calorimetry this must be done between Steps 2 and 3, by simply connecting the adsorption bulb to the manometric equipment. 

Numerical Procedure. This section describes an iterative numerical procedure for evaluating the mathematical model presented in this chapter for the nonsteady ignition and combustion of a fuel droplet The key step of this procedure is to match or couple the analytical equations for heat and mass transport at the liquid/gas interface by establishing the droplet surface temperature for a series of successive short time intervals. The numerical procedure for each time consists of the following steps ... 

To the filtered resin after step 6, add a soln of Boc amino acid (2.0 mmol), BOP (884 mg, 2.0 mmol), and HOBt (306 mg, 2.0 mmol) in the minimum amount of solvent needed to mix the resin. Add DIPEA (0.39 mL, 2.0 mmol). Mix until the Kaiser test is negative. The procedure is similar for couplings mediated by HATU (1 mmol = 380.2 mg), but in this case the DIPEA should be increased to 4 mmol. Since BOP does not activate TFA for reaction, the entire procedure in Section 4.3.2.1.2.1 can be shortened even further by eUmination of a separate neutralization step (step 5). In this case the well-washed resin after TFA deprotection is treated directly with the coupling mixture, and DIPEA is increased to neutralize all TFA salts on the resin. If the Kaiser test does not rapidly become negative, an additional equivalent of DIPEA should be added. The fact that TFA can bind nonstoichiometricaUy to peptide backbones means that additional DIPEA may be needed in certain cases when this modification is used. A large excess of base should be avoided, as it can promote racemi-zation. 

Procedural steps for setting up and running a reaction are shown in Table 5.2. Details are discussed in the sections below. 

D. Compounds or ions in which the central element needs a share in more than eight valence shell electrons to hold all the available electrons, A. Extra rules are added to steps 2 and 4 of the procedure in Section 7-5 when this is encountered.
