Paper Title:

Analysis of Factors Influencing Quality in Construction Projects using Relative Importance Index Method

Abstract:  The Infrastructure sector in India plays a vital role in the economic progress of the country. The need for achieving quality of the finished product in the public infrastructure is very important. Quality is an essential element for sustainable infrastructure development. Quality in its simplest form can be defined as ‘meeting the customer expectations’. This study is intended to provide clients, consultants and contractors with necessary information needed to better manage the quality of a public infrastructure construction projects by identify the factors that affect process quality of projects and to rank them by degree of importance. Certain organisations are identified and a questionnaire survey was carried out there. Then the data’s from the organisation was collected. The ranking of the factors is done by using Relative Importance Index. Using that data’s the major factors that affecting the quality have to be identified. Then from the results suitable suggestions was given to the organisations for improving their product & service quality

Paper Title:

Structural, Optical and Morphological studies of Graphene Oxide produced by Improved Synthesis

Abstract: Nanotechnology is a cutting-edge research in materials, energy, sensors, biotechnology and defence systems. One of the crucial bottlenecks of modern technology is cost and scalability. In this respect, Graphene Oxide (GO) has gained significant attention. GO is often described as an electrical insulator, due to the disruption of its sp2 bonding network. In order to recover the honeycomb hexagonal lattice and the electrical conductivity, the reduction of the GO has to be achieved. This remains an important property when mixing with polymers or ceramics matrixes to improve their electrical and mechanical properties. The GO used in this study was prepared by and modified Hummer’s method. The structural properties were investigated by X-ray diffraction. The optical properties were studied by UV-Vis absorption spectra and FT-IR spectroscopy; furthermore, scanning and transmission microscopy analysis was done to study its morphology.  In the study we successfully synthesized GO by modified Hummer’s method, and the results indicated higher interlayer spacing.
