The electrospinng of PAN and PAN/CNT composite webs is carried out with the commercially available Nanospider machine. The webs are spun under similar processes and coated on Polypropylene spun bonded nonwoven fabric. This research work reports on the influence of multi-walled carbon nano tube (MWCNT) on the morphology, tensile properties, conductivity, thermal, chemical and crystalline structure of PAN and PAN/CNT composite nanofibrous webs. The morphological developments are explained on the basis of nanofibre diameter and web density as depicted by FESEM images. An addition of CNT greatly affects the morphology of webs, increases fibre diameter, decreases web density and leads to a roughened web surface. The mechanical properties of PAN /CNT composite webs are also found to be influenced by CNT concentration. The addition of MWCNT to PAN enhances the conductive properties of webs. The specific conductivity of PAN/CNT composite webs is found to be in order of 10^-6 S/cm, which falls in the semiconducting regime and follows Ohm's law of conductivity. The TGA plots confirmed that the PAN/CNT composite web is more thermally stable than the PAN web. The presence of CNT in the polymer matrix is evidenced by D and G band, indicating a successful electrospun coating process.

The purpose of this paper is to investigate the Web Impact Factor of Arab universities.

The study included 99 universities representing 20 Arab countries. The advanced search facility of AltaVista was used for data collection. Two rounds of data collection were conducted to retrieve the links as well as the web presence of the included universities.

Jordanian universities represent 40 per cent of the top ten universities with the revised web impact factor. However, this was not the case in terms of the universities' web presence. Results indicated a strong correlation between external links and web presence.

The variability of search engine results and the unavailability of some university web sites are limitations to the study.

By investigating, for the first time, the Web Impact Factors of Arab universities as well as the relation to other variables such as language, the paper will provide universities with some measure of how they are viewed by the outside world.

The purpose of this paper is to highlight the potential of web components for libraries.

The paper introduces a working example web component that reimplements an OCLC WorldCat search widget.

By exploring the case study, the paper explains the functioning of web components and the potential advantages of web components for library web development.

Increasingly, web components are being used within library web development, but there is scope for much greater use of this technology to the advantage of those libraries involved.

This paper aims to explain the historic development of Web from the first generation to the second generation and now to the upcoming, third generation of the Web. It describes the importance of Web 3.0 and its other sub-functions to the librarians and their importance in the libraries. The basic purpose of this study is to give librarians an insight about the upcoming technologies.

This paper is designed as an explanatory study using historic and literature search techniques, and is presented in an essay format containing the brief history of web, its current and coming technologies and its advantages and disadvantages.

The finding and results indicate how the Web was designed into its current form. Findings show that at the next level, the interactions will become three ways. The robotics, artificial intelligence and semantic systems will help human in solving their queries.

The Web is spreading while new applications and technologies are inventing every day. This research may not be containing all the Web 3.0 applications, advantages and drawbacks.

This paper includes the details of the Web applications that are used in Web 3.0. This article not only gives an insight to the Web applications related to the libraries but also indicates the advantages and drawbacks.

This paper points out some very important applications to be used in the libraries in Web 3.0 environment, while a consideration of advantages and drawbacks makes this research more valuable for the librarians.

The rapid adoption of the Web as a commercial medium has caused firms to experiment with innovative ways of doing business. Those firms that effectively market themselves on the Web have a distinct advantage. This paper presents two e‐commerce Web site design strategies and 12 e‐commerce models for gaining that advantage.

There are two main objectives of the paper. First, in a systematic and statistically rigorous manner, we attempt to descriptively document the types and nature of marketing information on commercial home‐pages, with a view to identifying the major objectives of contemporary commercial Web sites that pre‐dominate the Web. Using Resnik and Stern’s “information content” paradigm, we evaluate the informativeness of commercial home pages. Second, we attempt to empirically examine various important factors of commercial home‐pages that lead to increased visits, or hit‐rates. The identification of hit‐rate determinants is likely to be of great value, both to Web page designers and to the many small and large firms seeking to establish their presence on the Web.

This paper presents the major findings from the project “Development of new methods for evaluation of library Web sites on the World Wide Web”. The report includes a brief examination and discussion of quality applied to Web sites in general and concerning library Web sites in particular. Findings from a few empirical surveys are presented. A new list of quality criteria for evaluation of academic libraries is compiled. The list is tested on three Danish academic libraries. Finally, a revised list of criteria is applied to twelve major Danish academic libraries. The findings include the panellists’ scores and their verbal comments. The main conclusion is that the Web sites of the Danish academic libraries in question are above average compared with Web sites in general. They do not, however, come up to expectations as virtual expressions of the quality levels of the libraries. This situation can only be improved if the libraries allocate the necessary resources regarding updating and development of the Web sites. This should be done on the basis of regular user studies and comparative evaluations.

Digital information retrieval has been as a problem, and at the same time a research interest for information scientists in recent years. They have planned some solutions to solve problems manifested during the 1990s. Designing meta‐tags and applying them to HTML documents was a remedy in this direction. Meta‐tags can help authors, publishers and indexers of Web pages to analyze intended content more precisely and efficiently. The aim of the present survey is to measure meta‐tags of the Iranian Web sites in accordance with an international criterion. To carry out the research, 346 Iranian Web sites were selected among 3,342, which represented a sample of all Web sites existed in Iranhoo, an Iranian Web directory. The source codes of the sample home pages were reviewed in terms of the presence of keywords and description meta‐tags. The findings of the survey showed that 31.5 percent and 24.6 percent of the Iranian Web sites have keywords and description meta‐tags respectively. The paper concludes that the Iranian Web sites are lower than non‐Iranian Web sites in terms of the use of meta‐tags.
