The greatest challenge for construction industry in the present times is realization of projects aimed at infrastructure development in harmony with the sustainable development concept. Sustainable development means, judicious use of natural resources for various construction activities. The construction industry, due to its huge size to meet the growing needs of construction activities, is the largest consumer of natural resources such as aggregates, cement (made from lime available naturally) and water etc. To achieve sustainable development in construction sector, it is necessary to replace some of these materials with the alternative materials, which are basically by-products/or waste materials from industries, such as fly ash, granulated slag, silica fume, and their disposal is an environmental threat. These alternative materials not only benefit the environment but also add value to, in the form of enhancement of performance characteristics by judicious selection and proportioning and use. In this study fly ash (FA) and bagasse ash (BA), obtained from fired at controlled conditions, are admixed with Portland cement at different replacement levels. The properties of concrete investigated include compressive strength, splitting tensile strength, modulus of elasticity, modulus of rupture and resistance to chloride ion penetration. Optimum percentage of FA and BA for strength development along with other results are discussed in detail.Full Text

Virtual Path (VP) bandwidth control improves transmission efficiency in an ATM network. An accurate estimate of the bandwidth-demand within a VP leads to efficient VP bandwidth control. So far the statistical methods were employed to predict the bandwidth-demand. We present a scheme based on the Evolutionary Genetic Approach to predict the bandwidth-demand patterns in VPs. The efficiency of this approach, quantified in terms of the Degree of Learning (DoL), is evaluated through simulation and the results are presented. Simulation studies on the effectiveness of the EGA on an ATM network and their results were presented.Keywords
ATM Networks, VP Bandwidth Management, Genetic Algorithms, Bandwidth-demand Patterns, Degree of LearningFull Text

A study was carried out to evaluate Boswellia serrata on adjuvant induced oxidative stress in rats. Intradermal administration of Freund’s adjuvant to induce rheumatoid arthritis consequently produced oxidative damage as indicated by an increase in thiobarbituric acid reducing substances, myeloperoxidase, protein carbonyls and a reduction in superoxide dismutase, catalase, glutathione peroxidase and reduced glutathione in tissue homogenates. Oral administration of methanolic extracts ofBoswellia serrata at 500 mg/kg body weight re-established the antioxidant profile. Co-treatment with an anti-inflammatory agent, meloxicam showed an enhanced healing effect. Hence, a significant restorative effect was witnessed with the herbal adaptogen Boswellia serrata.Keywords
