The higher the value of the DCFRR for a project, the more attractive it is. The minimum acceptable value of the DCFRR is the market interest rate. If the DCFRR is lower than market interest rate, it would be better to put money in the bank. For a DCFRR value greater than this, the project will show a profit for a lesser value, it will show a loss. 

The DIPPR is a research organization sponsored by the AlChE (American Institute of Chemical Engineers). Its objective is to develop a thermophysical data bank for the components most frequently encountered in the chemical industry. 

When data for a particular component can not be obtained from data banks, the engineer has two choices ... 

Using computer programs compiicates the problem because the calculation accuracy is never given for commercial reasons. Furthermore, the ways in which the methods are executed are not explicit and the data banks are often considered secret and inaccessible. 

The environmental performance of companies within the industry is normally subject to the legislative requirements of the host government, but is increasingly becoming scrutinised by the public, as available information and general levels of awareness increase. Major companies see responsible management of the environmental aspects of their operations as crucial to the future of their business. The approval of loans from major banks for project finance is usually conditional on acceptable environmental management. 

Suppose you have to meet an obligation to pay a bill of 10,000 in 5 years time. If you could be guaranteed a compound interest rate in your bank of 7% per annum (after tax) over each of the next 5 years, then the sum which you would have to invest today to be able to meet the obligation in 5 years time would be ... 

If you were offered 7,130 today, or 10,000 in exactly 5 years time, you should be indifferent to the options, unless you could find an alternative investment opportunity which yielded a guaranteed interest rate better than the bank (in which case you should accept the money today and take the alternative investment opportunity). 

The closest analogy to a project investment is to consider how much you are required to pay today for the promise of 10,000 in 5 years time. Assuming the only options are the bank or the offer, then the maximum you should be prepared to pay today is 7,130. If you are requested to pay more, then you would do better by putting the 7,130 in the bank. 

In the above example, the discount rate used was the annual compound interest rate offered by the bank. In business investment opportunities the appropriate discount rate is the cost of capital to the company. This may be calculated in different ways, but should always reflect how much it costs the oil company to borrow the money which it uses to invest in its projects. This may be a weighted average of the cost of the share capital and loan capital of a company.

At present, all over the world the X-ray television systems, instruments based on magnetic heat and eddy-current methods are used to check the air-passengers luggage and to check staff when entering the hazardous objects. In banks, security services and etc. the optic-television and endoscopic technical vision systems are widely used.

These tests generate several Gigabytes of data that are fed into a historical database. Although most of the analysis is performed automatically, human interaction is still needed to compare current and past data. Data are stored on optical CD S s from which the historical data bank are retrieved during field inspections from a mobile unit. Each of these is equipped with a CD-jukebox linked to an analysis station. The jukebox can handle 100 CD s, enough to store all previously recorded data. A dedicated software pre-fetches the historical data and compares it on-line with the newly acquired NDT-data. It is based on fuzzy algorithms applied to signal features. 

After inspecting a bank of near drum generator tubes using full coverage scans, the following information can be obtained ... 

Most recovery boilers use 63,5 mm OD carbon steel tubes in the generating bank. With a few exceptions these tubes are swaged at the ends to 50,8 mm. When the 63,5 mm raw tube is manufactured it is subject to a lot of specifications i.e. ASME. There are no specifications for the swaged end of the tube. This is unfortunate as the swaged part of the tube is subjected to further mechanical deformation dtuing the rolling procedure and is located in a wastage zone of tire recovery boiler. 

In several generating banks inspected, a number of tubes have been found with eccentricity exceeding 1,0 mm and in one extreme case 2,0 mm, or 40 % of the nominal wall thickness was noted. A conceptual diagram of tire cross section of a concentric tube and a simulated plot of the wall thickness scan is presented in figure 3. The scan presented in figure 2 is a relatively concentric tube less than 0,2 mm of wall variation. 

Near drum wastage is the most prevalent type of wastage documented. It cart be found anywhere in the generating bank but is most common on the wall tubes, in tlic row immediately next to soot blower lanes and in the hot and cold row s. Three types of near drum w astagc have been documented.

We tested our new potential by applying a local optimization procedure to the potential of some proteins, starting with the native structure as given in the Brookhaven Protein Data Bank, and observing how far the coordinates moved through local optimization. For a good potential, one expects the optimizer to be close to the native structure. As in Ulrich et al. [34], we measure the distance between optimizer B and native structure A by the distance matrix error...

PDB file. pdb Protein Data Bank file format for 3D stmcture information on proteins and polynucleotides nmm.rcsb.org 53... 

In 1971 the Protein Data Bank - PDB [146] (see Section 5.8 for a complete story and description) - was established at Brookhaven National Laboratories - BNL -as an archive for biological macromolccular cr7stal structures. This database moved in 1998 to the Research Collaboratory for Structural Bioinformatics -RCSB. A key component in the creation of such a public archive of information was the development of a method for effreient and uniform capture and curation of the data [147], The result of the effort was the PDB file format [53], which evolved over time through several different and non-uniform versions. Nevertheless, the PDB file format has become the standard representation for exchanging inacromolecular information derived from X-ray diffraction and NMR studies, primarily for proteins and nucleic acids. In 1998 the database was moved to the Research Collaboratory for Structural Bioinformatics - RCSB. 

Having looked at the general structure of PDB files, let us now examine a sample PDB file. The file represents the structure of r conotoxin PNll polypeptide (PDB ID Ipcn) and was retrieved from the Protein Data Bank [53]. Figure 2-109 shows the 3D structure of the molecule. 

The fir.-fit line of the file (see Figure 2-110) - the HEADER record - hold.s the moleculc. s classification string (columns 11-50), the deposition date (the date when the data were received by the PDB) in columns 51-59, and the PDB (Dcode for the molecule, which is unique within the Protein Data Bank, in columns 63-66. The second line - the TITLE record - contains the title of the experiment or the analysis that is represented in the entry. The subsequent records contain a more detailed description of the macromolecular content of the entiy (COMPND), the biological and/or chemical source ofeach biological molecule in the entiy (SOURCE), a set ofkeywords relevant to the entiy (KEYWDS). information about the experiment (EXPDTA), a list of people responsible for the contents of this entiy (.AUTHOR), a history of modifications made to this entiy since its release (REVDAT), and finally the primaiy literature citation that describes the experiment which resulted in the deposited dataset ()RNL). 

As this short example shows. PDB files use different syntax for different records and both writing and reading such files require much effort. Another problem is the extensibility of this format to handle new kinds of information, which further complicates the file structure. The Protein Data Bank has been faced with the consequences - the existing legacy data comply with several different PDB formats, so they are not uniform and they arc more difEcuh to handle (145, 155, 157]. As mentioned in Section 2,9.7.1, there is a much more flexible and general way of representing molecular structure codes and associated information - the STAR file format and the file formats based on it. 

D structures of macromolecules, especially proteins and nudeic adds, are found in the Protein Data Bank (PDB) [27].
