The chemical and petrochemical industries are highly capital intensive and this has two important implications for the plant designer. Before the expenditure for any plant is approved, a discounted cash flow (DCF) return on capital invested is projected (Section 9.1). The capital cost of the plant is a key factor in deciding whether the DCF return is above or below the cut-off value used by a company to judge the viability of projects. Thus, there is always strong pressure on the materials engineer not to overspecify the materials of construction. 

Fischer projection (Section 25.2) A means of depicting the absolute configuration of a chiral molecule on a flat page. A Fischer projection uses a cross to represent the chirality center. The horizontal arms of the cross represent bonds coming out of the plane of the page, and the vertical arms of the cross represent bonds going back into the plane of the page. 

Newman projection (Section 3.6) A means of indicating stereochemical relationships between substituent groups on neighboring carbons. The carbon-carbon bond is viewed end-on, and the carbons are indicated by a circle. Bonds radiating from the center of Ihe circle are attached to the front carbon, and bonds radiating from the edge of the circle are attached to the rear carbon. 

The WT lipase leads to an ee value of only 38% in favor of the (If ,45) enantiomer. The application of low-error epPCR increased the enantioselectivity slightly, but high-error rate epPCR turned out to be more successful, with several mutants showing ee values of 54-58% (45,137). The results are in line with the experience gained in the Pseudomonas aeruginosa lipase project (Section IV.A. 1). Of course, a library produced by high mutation rate can also contain hits that have only one amino acid exchange, and this was indeed observed in several cases. 

We will continue with the schematic from the previous section. The schematic was saved as Section 7 A. Open project Section 7A.opj and open the schematic. 

The new model is listed in the left window pane, indicating that it has been added to the library for the project, Section 7A.lib. Select File and then Exit to close the Model Editor window and return to the schematic ... 

We assess the economic incentives and their impacts resulting from allocation to new projects of power generators. All Member States have made provisions that guarantee a certain volume of free allowances to new entrants for a defined period. Section 3.1 uses a simple analytic model to illustrate the impact of a uniform allocation of C02 allowances to all new projects, Section 3.2... 

Fischer projection (Section 7.8) A two-dimensional drawing of a chiral molecule in which the chirality center is represented as a cross with the atom at its coiter. Although the four bonds to the chirality center are shown in the plane of the page, the horizontal bonds project above the plane of the page and the vertical bonds project behind the page. 

Newman projection (Section 6.3) An end-on view of a bond so that one atom of die bond is directly behind the other. By convention, the from atom is represented by the intersection of its bonds and the back atom is represented by a circle.

Figure 2 Establishment of a Project Plan Sequencing of Project Sections and Tasks...

Sequencing of project sections or tasks can be performed in different ways. The example in Figure 2 is displayed as a Gantt (proprietary name) chart which shows the duration of tasks as horizontal bars. Because of their clarity Gantt charts are a preferred means to present project plans. 

The approach shown in Figure 2 consists of two steps. At first the tasks within each of the four project sections are timed and sequenced. Dividing the project into sections makes this step easier because less complex task links need to be considered. 

Once the logic of the project sections is established, the draft plan is checked for remaining dependencies between the sections. In a second step, entire project sections are rearranged and overlapped where possible and necessary, according to the relatedness of tasks in different sections. 

Two major conflicts in terms of task dependencies between project sections remain in the example of Figure 2 (upper half) after a first arrangement of the different tasks within each of the four sections. In order to get an antigen which is immunogenic in mice and rabbits (see 11/1) at least some immunization experiments with Antigen X (task... 

Of course other aspects such as time requirements, time constraints, risk factors and resources should also be considered from this stage onwards to arrange project sections and tasks in an appropriate order. 

JI (from an experiment by Viktor Obendrauf) 22-24, CD. The answers to selected problems from the various experiments are given in the book s website at www.springer.com. Many open-ended projects are suggested in the additional related projects section of each experiment. 

Haworth projection (Section 27.6A) A representation of the cyclic form of a monosaccharide in which the ring is drawn flat. 

Newman projection (Section 4.9) An end-on representation of the conformation of a molecule. The Newman projection shows the three groups bonded to each carbon atom in a particular C—C bond, as well as the dihedral angle that separates the groups on each carbon. 

This chapter gives an overview of the simulation of design processes and its current and possible future applications in industry. Therefore, the fields of activity of the industrial partners are described in Sect. 7.4.2. Section 7.4.3 subsumes the goals and strategies which are pursued in this project. Section... 

Fischer projection (Section 7.7) Method for representing stereochemical relationships. The four bonds to a stereogenic carbon are represented by a cross. The horizontal bonds are understood to project toward the viewer and the vertical bonds away from the viewer. 

Is the number of modules constant among the mammalian species and are they correlated with the different forms of chemoarchitectonic zonation in the cortex and the white matter These questions only can be answered after a more thorough review of the corticonuclear projection (Sections 6.1.1., 6.1.2., 6.1.4. and 6.1.5.), the chemoarchitectonic evidence on zonation (Section 6.1.3.) and the olivocerebellar and nucleo-cerebellar projections (Section 6.3.) in different mammalian species. The existence of such a basic plan has been questioned (Boegman et al., 1988), not so much because the different maps for parasagittal zonation are mutually exclusive, but mainly because most... 

It is important to note that these molecular structures, as for all data in the calc-result section, are read only and cannot be modified. Instead, you have to copy the resulting structure to a new molecule in the project section. 

In the large majority of cases, however, the object and constraint functions are so complicated that an analytical elimination of a variable is essentially intractable, and this is especially true when there is more than one constraint. The main exception is when the constraint equation is linear, in which case it can be considered as a vector in the coordinate space. Instead of eliminating a variable explicitly, the constraint condition can be fulfilled by removing the corresponding component of the object function by projection (Section 16.4), and performing the optimization on f. ... 

If there are real frequencies of the same magnitude as the rotational frequencies , mixing may occur and result in inaccurate values for the true vibrations. For this reason, the translational and rotational degrees of freedom are normally removed by projection (Section 16.4) from the force constant matrix before diagonalization.
