Design and Development of Web-Based Databases of Current Periodicals at Indian Institute of Technology, Kharagpur

The library of the Indian Institute of Technology, Kharagpur (IITKGP) was the first library in India which attempted to set up an electronic library for its clientele under the auspices of AICTE. While placing the library of IITKGP on Internet, the facilities offered by the WWW are exploited to provide information services of more than 1000 current periodical titles (with hard copy to on-line). This paper begins with a brief description of the electronic resources available in the Central Library, IITKGP. As the web sites are being set up by the libraries of all IITs, it is emphasized that the use of Internet will enable to share their resources in general and periodical publications in particular. Highlights the various types of web-based information services on scholarly journals including electronic journals (full text) which are linked to publishers’ addresses. Discusses the methods, with illustrative examples, associated with the creation of several web-based tools like alphabetical list of periodicals including availability of CD-ROM databases, both in full text as well as abstracting and indexing journals, on-line journals (full text), departmentwise list of periodicals, current arrival list of periodicals, union list of periodicals (3500) subscribed by all IITs for resource sharing purpose and other free on-line services provided by the various publishers. Key word search program, hardware and software requirements, HTML tags to create several hyper linked files, editors and Internet solution for automatic web-page designing are also presented

Thermodynamics and kinetics of reactions in protective coating systems

A study of the aluminization of Ni from packs containing various percentages of unalloyed Al confirmed that the surface aluminum content of specimens aluminized tends to decrease with time and consequently a simple parabolic law for the weight-gain vs. time relationship is not obeyed. The diffusivity-composition relationship in NiAl was examined, and a set of curves is presented. A numerical method for the calculation of coating dissolution rates was developed and applied to NiAl-Ni3Al type of coatings

On the kinetics of pack aluminization

A theory of pack aluminization has been formulated by combining gaseous and solid-state diffusion rates. This theory relates the surface composition of the coating and therefore, in principle, the phase morphology and the growth rate of the coating, to pack operating parameters such as pack aluminum density, type of activator, temperature and others. Experimental data on the aluminization of unalloyed nickel in pure aluminum packs obtained to date are in good agreement with the predictions of the theory

Effect of compatibilizer on the dynamic mechanical and electrical properties of kaolin clay reinforced EPDM rubber

Industrial pollution issue and dark colour of carbon black, clay based non black filler are getting more importance for reinforcing elastomer. EPDM-Kaolin composites with various maleated EPDM concentration have been prepared by mixing on a two roll mill. The rheometry data showed the optimum cure time increases with increasing compatibilizer concentration without decreasing torque value indicating that acidic functional groups comes from compatibilizer could retard cure rate and increase the optimum cure time rather than change in the ultimate cure state. As the filler concentration increases, the edge to edge and face to edge interaction between filler and EPDM increases and the free volume between EPDM molecules is reduced, the storage modulus increases. Moreover, the dynamic mechanical analysis also showed the increase in glass transition temperature with increase in filler concentration due to the inter-tubular diffusion of EPDM inside the clay. It was also observed that with increasing filler concentration, the resistivity and dielectric strength decreases and moreover with increasing compatibilizer concentration the resistivity decreases due to better dispersion of filler helps to build conduction path. The morphological study also revealed that homogeneity of filler dispersion increases with increase in compatibilizer concentration

Food Crisis and Sustainable Food Security in India

The world population is rising rapidly over the growth of food grains and as a consequence food crisis arises. There are now more than a billion malnourished people in the world meaning that almost one sixth of humanity is suffering from hunger. Fertility of land has been reduced due to over exploitation, excessive use of chemical fertilisers, insecticides and pesticides. Due to indiscriminate deforestation the amount of rainfall reduces and land erosion takes place. Natural calamities like droughts, floods, cyclones, global warming, melting glaciers, raising sea level etc. are increasing and environment is degraded. As a result the production of food grains decreases and made food crisis at a global level. Not only that sometimes food crisis arises not due to food shortage, there is enough food in the stock though some people are in starvation due to some failure of public distribution system. The crisis not food crisis, it is the policy crisis of the government. This is a tragedy from food surplus to food scarcity. This paper concentrates on sustainable food security in the long-run in a sustainable eco-friendly manner to cover the benefit every person not only for the present but also for the future generation. Kew words: Sustainable, public distribution system, body mass index, bio-fuels, green revolution, below poverty lin

Service Quality Perspectives in Telecommunication Sector: Trust and Loyalty Investigation

The goal of this paper is to investigate the effect on trust and loyalty in internet services of functional and technological service quality. We have received 300 internet service users from different cities in Iraqi Kurdistan Region. The date has been evaluated through structural equations modeling. The results reveal that technical quality has more impact on trust and loyalty than functional quality does. Secondly, it was observed that technical quality impacts both trust and loyalty directly while function al quality has only indirect relationship with loyalty over trust. We have given managerial implications to the managers in the sector
