World Wide Web

The World Wide Web is the main information source which combines many resources.

In the first edition of this book I wrote, A major use of the Internet is for electronic mail, but extremely rapid growth is being observed in other areas, particularly the "World-Wide Web" (WWW).... Such a phrase seems an understatement despite the hype, the Internet has certainly made a dramatic impact, not least on the scientific community, where its... 

A number of structured databases have been developed to classify proteins according to the three-dimensional structures. Many of these are accessible via the World Wide Web, T1 protein databanlc (PDB [Bernstein d al. 1977]) is the primary source of data about the stru tures of biological macromolecules and contains a large number of structures, but many i these are of identical proteins (complexed with different ligands or determined at differet resolutions) or are of close homologues. 

This is necessarily an incomplete list more comprehensive glossaries can be found el where (particularly on the World Wide Web). 

The three basic Internet appHcations of remote login, electronic mad, and file transfer are also budding blocks of more sophisticated appHcations that offer increased functionaUty and ease of network use. Tools such as Gopher, Wide Area Information Servers (WAIS), and World Wide Web (WWW) go beyond the three basic Internet functions to make information on the network easier to locate and use. Detaded descriptions of these tools are avadable (10). This trend toward more powerful, user-friendly networked information resource access systems should continue as Internet grows and matures.

The Internet s growth is amazing. Investor s Business Daily reported on a research study by International Data Corp. that showed commercial sites on the World Wide Web grew by more than 45,000 in 1996.

Figure 2.10 Examples of schematic diagrams of the type pioneered by Jane Richardson. Diagram (a) illustrates the structure of myoglobin in the same orientation as the computer-drawn diagrams of Figures 2.9b-d. Diagram (b), which is adapted from J. Richardson, illustrates the structure of the enzyme triosephosphate isomerase, determined to 2.5 A resolution in the laboratory of David Phillips, Oxford University. Such diagrams can easily be obtained from databases of protein structures, such as PDB, SCOP or CATH, available on the World Wide Web.

The first requirement for threading is to have a database of all the known different protein folds. Eisenberg has used his own library of about 800 folds, which represents a minimally redundant set of the more than 6000 structures deposited at the Protein Data Bank. Other groups use databases available on the World Wide Web, where the folds are hierarchically ordered according to structural and functional similarities, such as SCOP, designed by Alexey Murzin and Cyrus Chothia in Cambridge, UK. 

The World Wide Web has transformed the way in which we obtain and analyze published information on proteins. What only a few years ago would take days or weeks and require the use of expensive computer workstations can now be achieved in a few minutes or hours using personal computers, both PCs and Macintosh, connected to the internet. The Web contains hundreds of sites of Interest to molecular biologists, many of which are listed in Pedro s BioMolecular Research Tools (http // www.fmi.ch/biology/research tools.html). Many sites provide free access to databases that make it very easy to obtain information on structurally related proteins, the amino acid sequences of homologous proteins, relevant literature references, medical information and metabolic pathways. This development has opened up new opportunities for even non-specialists to view and manipulate a structure of interest or to carry out amino-acid sequence comparisons, and one can now rapidly obtain an overview of a particular area of molecular biology. We shall here describe some Web sites that are of interest from a structural point of view. Updated links to these sites can be found in the Introduction to Protein Structure Web site (http // WWW.ProteinStructure.com/). 

There are literally many thousands of chemical compounds that may pose potential air pollution problems. It would be impossible to present all the pertinent data and information needed to evaluate each and every air pollution scenario. There are, however, a wealth of information and data bases that are available on the World Wide Web, along with a number of standard hard copy references to obtain information on the chemical and physical properties, and health risks of potential atmospheric contaminants. Chapter 3 provides information on the following three areas ... 

There are many excellent textbooks on the subject of distillation, however with the explosion of information on the World Wide Web, process engineers can now gain almost instant access to calculation methods and model simulations which will walk the engineer through the important design steps. The following Web sites are recommended to be reviewed and accessed by the reader. 

These faetors are attributed to bateh and semi-bateh proeesses rather than eontinuous proeesses. However, the use of eontinuous proeesses on fine ehemieal manufaeturing sites is limited. It is often preferable to use the semi-bateh mode as opposed to bateh proeesses. The Appendix lists hazards of pertinent ehemieal reaetions for toxie and reaetive hazards ehemieals. Information eoneerning the safety of various ehemieals (e.g., ammonia and others) ean be readily obtained from the World Wide Web. Table 12-1 shows how to aeeess a material safety data sheet at the Vermont Safety Information (VIRI) site on the Internet. 

Minimum computer requirements to run THERdbASE are a 486 CPU, IBM or clone, at leasi 8 MB of RAM, at least 40 MB of disk space, color VGA monitor, a mouse, Microsoft Windows. v I To install THERdbASE, execute the File/Run option from within Windows and specify SETUP.F.XE found in the THERDCD directory.
