Abstract: In present paper experimental investigations are carried out to study the effect of Aluminium oxide (Al2O3) nanoparticles to remove Heavy metals Cu and Ni in simulated wastewaters with different experimental conditions. The experiments are performed by varying pH, time of contact and speed of mixing and also the initial concentration of heavy metals in synthetic solution. Experiments conducted using Aluminium oxide (Al2O3) nanoparticles by varying pH, time, Al2O3   dosage, concentration and speed of rotation. The result represents the reduction of Cu at 9 pH. The percentage removal after the addition of Al2O3 is observed to be as 95%.

Abstract: Construction is the world’s largest cash flowing industry. The successful completion of any construction project within budget and time is depends on skill of planning manager and control and monitor system of the construction site. The productivity tracking is one of the effective recent methods to control the project workflow with available resource. This paper shows how the project should be monitor by productivity of site with the help of Earned value analysis method. The data which going to analyzed in this paper is real site data and given by respective planning manager for education purpose. The major activity deals the entire site productivity and overall performance is taken into consideration. The result of this analysis shows the deviation of planned and actual work done of activity in site and warning sign to project manager from cost overrun and suggestions to improve productivity in site. It is possible to predict the exact scenario of construction site by this analysis before any major occurrence of loss.

Abstract: The prime objective of the project is to determine the stiffness of the outer race of the aircraft bearing used in auxiliary gearbox. The main need of the project reflects in the conclusion derived from the data after calculation and analysis that it gives the minimum necessary value and maximum limits of the dimensions, and stiffness for the given material required for the outer race of the bearing which was designed and analyzed based on the data.  Other data such as Bulk modulus, Rigidity modulus etc., could be calculated from the Stiffness found out for the bearing. Here the changes are made to the dimensions of the outer race in the design stage and the results are simulated in software solution, based on which we can reach a conclusion.  Respective data for designing the outer race such as dimension, material of the outer race, standard procedures for design and analysis were followed by reference from standard books, papers and under guidance and discretion of respondents at CVRDE.
