On the Internet

The NDT Newsgroup and other forums are playing an important role in expediting meeting and communieation among your NDT colleagues on the Internet - Email is the most important tool for that. Not only technical discussions but also business to business or even direct inquiries are today handled via the Internet. Statistics are presented with more information on specific usage. 

The first full text NDT Journal on www.ndt.net, the Online Journal of Nondestructive Testing Ultrasonics, is on the Internet and each month provides new information as well as a comprehensive overall reference - access is free since it is sponsored by the NDT online exhibition. 

Once you have a website, there is another question how easy it will be to find your page on the Internet You will need Internet advertising to be visible on the Internet ... 

Some may say "We have invested in our own Internet presence (Home Page), so why we should advertise on the Internet Simply informing your established customers of your new Internet address is not sufficient. We ve already discussed some of the challenges users may face in searching for information. Your potential customer may lack the patience to follow hundreds of links of search engine output.

Many biochemical databases with sophisticated topics have been developed for solving various problems. Since 1996 the first issue of each journal volume of Nucleic Acid Research has been reserved for the presentation of molecular biology databases [28]. A comprehensive catalog on the Internet is DBCAT, currently listing 511 databases [29, 30). 

Scientific, and especially chemical, information is becoming increasingly available on the Internet. This has the advantage that the information is accessible to other users. Additionally, the data formats (HTML, PDF, GIF, etc.) that are used are restricted to the most important ones to provide standards that are readable worldwide. Unfortunately, however, much of the information on the Internet is not reviewed or verified by other organizations as is the case in the primary literature. Thus, the quality of the information is extremely variable. 

The huge number of websites on the Internet (about 2,5 billion web pages December, 2002) containing chemical information is a great challenge when one is attempting to find specific information on a topic. Therefore numerous search engines have been developed and offered that provide fast access to the data. 

Given the enormous number of resources for chemical information available, many researchers do not have the time to learn the details of the variotis systems, and they end up searching in only a few resources with which they are familiar. This is a dangerous approach Knowing that both fee and non-fee resources are available on the Internet and both hold the desired information, it is prudent to search non-fee systems first and then use proprietary databases to fill data gaps [49].

Environmental information is available extensively on the free Internet. Two main reasons aeeount for this. First, the freedom of environmental information law and, secondly, the fact that many environmental databases which used to be available only commercially are now accessible on the free Internet. This section focuses on environmental information which is available free of charge on the Internet. Three main paths are distinguished for searching environmental information effectively. In general, all three routes should be taken into consideration for achieving a sound search result for environmental information on chemical stibstances... 

The word portal is often used for web sites that function as an entiy to a repo-sitoiy of information on almost any topic on the Internet. The following portal categories for chemical issues arc distinguished general chemistry sites substance information sites analytical chemistiy sites enviromnental chemistry sites toxicology and occupational health sites as well as patent seiwices [47],...

Scientific and chemical information is becoming available increasingly on the Internet. 

A good source of information regarding the scientifre background of ab-initio and semi-empirical calculations are the manuals that accompany commercial software. Some of the documentation is available for evaluation on the Internet,...

The effort to clarify and articulate the principles of spectrometry as simply as possible appears to have struck a welcome response among those who use mass spectrometers. The original series was not advertised, but, once it had been discovered outside the Micromass organization, there were inquiries as to how it could be purchased. From the start. Micromass offered the series free in a ring-binder format and later also provided it free on CD ROM and then on the Internet. Updating of the first CD led to over 600 requests for it on the day after its release had been announced on the Internet. Partly because of this response — but mainly because users or potential users frequently like to have a traditional reference book — it was decided to publish the series in this present book form. 

SOCMA includes a magazine version of the commercial guide free to Informex attendees. Copies of this guide are also available direct from SOCMA for a fee. The SOCMA homepage on the Internet also provides a wealth of information. 

The easiest thing to do is to get the pump curve from the manufacturer because it has the NPSHr listed at different flows. Nowadays, you can get the pump curve on the Internet with an e-mail to the manufacturer, you can send a fax, or request the curve in the mail or with a local call to the pump representative or distributor. If you wanted to verify the NPSHr on your pump, you ll need a complete set of instrumentation a barometer gauge, compound pressure gauges corrected to the centerline of the pump, a flow meter, a velocity meter, and a thermometer. Definitely, it s easier to get the curve from your supplier. 

Nowadays,. some pump companies publish their lamily curves on the Internet. You can request a copy with an e-mail, phone call, fax, or letter. The curves and gauges are the difference between life and death of your pumps. The pump family curve goes hand in hand with the system curve, which we ll cover in the next chapter. 

It is well known that the resources available on the Internet are in constant flux, with new sites appearing on a daily basis and established sites disappearing almost as frequently. This also holds true for the dedicated tools used in biochemical and biophysical studies. New tools are constantly becoming available, and established tools, obsolete. Such rapid change makes it difficult to stay current with the state-of-the-art technologies in the areas of bioinformatics and computational biochemistry and biophysics. 

To help the reader keep abreast of these advances we present a list of useful WWW sites in this appendix. Realistically, this list should be updated on a daily basis as many of the tools offered on the Internet are made available not only by large organizations and research groups but also by individual researchers. The goal, therefore, has not been to provide a nearly complete guide to the WWW but rather to provide material representative of the tools useful to researchers in the fields of biochemistry and biophysics.

Yet another variant of self-assembly relies on the repulsion between blocks of suitably constituted block copolymers, leading to fine-scale patterns of organisation. One very recent description of this approach is by de Rosa et al. (2000). Details of this kind of approach as cultivated at Oak Ridge National Laboratory can also be found on the internet (ORNL 2000). 

In addition to printed compilations, more and more of the information is available on CD-ROM and latterly also on-line on the internet. This last is a feature of the service provided by MSI, Materials Science International Services in Stuttgart. This organisation, under the working name of MSIT Workplace (http //www.msiwp.com), provides information on the entire corpus of phase diagram compilations.
