Internet fundamentals

However, across the virtual divide ofthe Internet, fundamental questions remained. Determining what the customer really wanted, and what services product variations the business eould modify and/or deliver, remained as ehallenges. The demand chain was really about the informed customer, customers dictating what they wanted, where and why (Selen Soliman, 2002). 

Misconceptions about food additives are perpetuated in the media and popular press, and recently have been disseminated via the Internet. There is confusion about the sources and functions of these compounds. Consumers are confused, for example, about the relative safety of natural as opposed to artificial food ingredients. A number of studies have shown consumers suspicion of synthetic chemicals in foods which are seen as posing a higher health risk than natural ingredients (Sloan et al., 1986 McNutt et al., 1986 Crowe et al., 1992). Unrealistic fears about food additives may be attributed in part to the public s fundamental lack of understanding of toxicology, including the failure to appreciate the concept of dose or the body s capacity to metabolize and detoxify the myriad of food constituents people are exposed to daily (Jones, 1992). 

Fundamental distrust of the industry s ethics. The public realisation that research studies have been withheld from public view, or released in partial (and misleading) form, has created enormous pressures for industry to make information on all trials available via the internet. The delays in relabelling products, the precipitous withdrawal of widely marketed drugs and the failure to identify safety risks before approval (even when it was not scientifically possible to do so) gives support to the canard that companies put profits before people. And prosecutions of major companies for... 

It is not necessary to have a complete understanding of the Internet in order to tap into its vast resources. The fundamental concepts provided here will allow you to take advantage of two essential activities (1) biochemical literature searching and (2) using Web directories and biological databases. 

This unit will introduce two fundamental protocols—the Wilhelmy plate method (see Basic Protocol 1 and Alternate Protocol 1) and the du Noiiy ring method (see Alternate Protocol 2)—that can be used to determine static interfacial tension (Dukhin et al., 1995). Since the two methods use the same experimental setup, they will be discussed together. Two advanced protocols that have the capability to determine dynamic interfacial tension—the drop volume technique (see Basic Protocol 2) and the drop shape method (see Alternate Protocol 3)—will also be presented. The basic principles of each of these techniques will be briefly outlined in the Background Information. Critical Parameters as well as Time Considerations for the different tests will be discussed. References and Internet Resources are listed to provide a more in-depth understanding of each of these techniques and allow the reader to contact commercial vendors to obtain information about costs and availability of surface science instrumentation. 

The future will mainly bring developments in the field of technical ceramics. On The Internet I came across a report with the title Fundamental Research Needs in Ceramics which listed the following subjects for working groups in a 1997-workshop and so is trendsetting for the future ... 

Even after the slump ends, however, the market is unlikely ever to come close to its pre-2000 expectations because the premises of the boom were flawed. Fundamentally, the Internet does not consume a large fraction of U.S. electricity today, nor do personal computers, office equipment, and network equipment furthermore, the growth rate of power used by the Internet is much slower than the growth rate of the Internet itself.17... 

Currently, the best internet search engine in terms of giving relevant hits (providing your scientific keyword is not associated with a more mainstream non scientific topic) Internet course teaching powder diffraction from fundamentals through to Rietveld refinement Internet course teaching materials analysis by texture methods... 

To ensure the consitency with other NEA-TDB Reviews, the fundamental physical constants are taken from a publication by CODATA [86COD]. Those relevant to this review are listed in Table II-7. Note that updated values of the fundamental constants can be obtained from CODATA, notably through its Internet site. In most cases, recalculation of the NEA-TDB database entries with the updated values of the fundamental constants will not introduce significant (with respect to their quoted uncertainties) excursions from the current NEA-TDB selections. 

Second, there have been major advances in technical information in the last few years. It was therefore imperative that these advances be reported and discussed as needed. These include fundamentals, new approaches, and improved applications. Much better mathematical and statistical models are now available. Computers have become of ever-increasing importance, leading to much improved research, plant design, plant operations, and so forth. Several groups currently market important computer models, and these are reported here. In some cases, free information can be found on the Internet. For example, the National Institute of Standards and Technology (NIST) has made available a large statistics handbook at no charge. Chapter 3 of the current handbook emphasizes the applications of statistics to chemically oriented problems.
